15 - 25% = 14.47 ounces of shampoo
The original shampoo bottle held 12 ounces before the 25% increase to 15 ounces. For the tile cleanser, the percent by mass of HCl is calculated to be 14.84%. Discussions of consumer product concentrations, like laundry detergent costs per ounce, often involve linear relationships and predictive models.
The question requires understanding percent increase and how to calculate the original amount given the increased quantity. To find the original volume of the shampoo bottle before the 25% increase, we set up the equation where the original volume (V) times 1.25 (to represent the 25% increase) equals the new volume of 15 ounces:
V x 1.25 = 15 ounces
To solve for V, we divide both sides of the equation by 1.25:
V = 15 ounces / 1.25
V = 12 ounces
Therefore, the old bottle held 12 ounces of shampoo.
To address another concept related to consumer products, the question on mass percentage, namely the percent by mass of HCl in a tile cleanser, also represents a common mathematical calculation in consumer product information. The calculation is as follows:
Percent by mass = (mass of solute / total mass of solution) x 100%
Percent by mass of HCl = (135 g / (135 g + 775 g)) x 100%
Percent by mass of HCl = (135 g / 910 g) x 100%
Percent by mass of HCl = 14.84%
Thus, the bottle of tile cleanser has 14.84% by mass of HCl.
When discussing the cost per ounce of laundry detergent in different sizes, such as a 40 oz. size or a 90 oz. size, the concept of linear relationships may be explored, as well as the possibility of identifying outliers or considering the validity of predictive models like the least-squares line.
A survey found that women's heights are normally distributed with mean 63.9 in. and standard deviation 3.6 in. The survey also found that men's heights are normally distributed with mean 69.7 in. and standard deviation 3.6 in. Consider an executive jet that seats six with a doorway height of 55.9 in. Complete parts (a) through (c) below. a. What percentage of adult men can fit through the door without bending? The percentage of men who can fit without bending is 0.02%. (Round to two decimal places as needed.) b. Does the door design with a height of 55.9 in. appear to be adequate? Why didn't the engineers design a larger door?
Using the normal distribution, it is found that:
a) The percentage of men who can fit without bending is 0.02%.
b) A very small percentage of people can fit through the door, thus the dimensions are not adequate. Possible, the engineers did not design a large door because of engineering constraints.
In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.Item a:
Men have mean of 69.7 in, thus [tex]\mu = 69.7[/tex]Standard deviation of 3.6 in, thus [tex]\sigma = 3.6[/tex]The proportion is the p-value of Z when X = 55.9, thus:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{55.9 - 69.7}{3.6}[/tex]
[tex]Z = -3.83[/tex]
[tex]Z = -3.8[/tex] has a p-value of 0.0002.
0.0002 x 100% = 0.02%
The percentage of men who can fit without bending is 0.02%.
Item b:
A very small percentage of people can fit through the door, thus the dimensions are not adequate. Possible, the engineers did not design a large door because of engineering constraints.

a 34 gram sample of a substance that's used to treat thyroid disorders has a k-value of 0.137. find the substance's half-life, in days. round to the nearest tenths.
Answer:
5.1 days
Step-by-step explanation:
Given in the question,
initial amount of substance = 34 grams
k-value = 0.137
To find the half life of this substance we will use following formula
[tex]N(0)/2 = N(0)e^{-kt}[/tex]
here N(0) is initial amount of substance
t is time in days
Plug values in the formula
[tex]34 /2 = 34e^{-0.137t}[/tex]
1/2 = e^{-0.137t}
Take logarithm on both sides
ln(1/2) = ln( e^{-0.137t})
ln(1/2) = -0.137t
t = ln(1/2) / -0.137
t = 5.059
t ≈ 5.1 days (nearest to tenths)

A number from 8 to 15 is drawn at random. What is the probability that the number is an even number?
Answer:
The probability that the answer is an even number is 50%.
Step-by-step explanation:
There are 8 terms: 8, 9, 10, 11, 12, 13, 14, 15. Even numbers: 8, 10, 12, 14. So, 4 out of the 8 terms are even, which is equivalent to 50%.
The probability that the number is an even number is 1/2.
What is the probability?The probability is defined as the ratio of number of favourable outcomes and the the total number of possible outcome.
A number from 8 to 15 is drawn at random.
The number between 8 to 15 are 8, 9, 10, 11, 12, 13, 14, 15 = 8
Total even number = 8, 10, 12, 14 = 4
The probability that the number is an even number is;
[tex]\rm Probability =\dfrac{Total \ even \ number}{Total \ number}\\\\Probability =\dfrac{4}{8}\\\\Probability =\dfrac{1}{2}[/tex]
Hence, the probability that the number is an even number is 1/2.

[tex]f(x)=3x^2-4x+1[/tex] is a polynomial and thus continuous everywhere and differentiable on any open interval. (second option)
The MVT then guarantees the existence of [tex]c\in(0,2)[/tex] such that
[tex]f'(c)=\dfrac{f(2)-f(0)}{2-0}=\dfrac{5-1}2=2[/tex]
We have
[tex]f'(x)=6x-4[/tex]
so
[tex]6c-4=2\implies6c=6\implies c=1[/tex]
The true statement is: (b) Yes, f is continuous on [0, 2] and differentiable on (0, 2) since polynomials are continuous and differentiable
Mean value theorem states that:
If [tex]\mathbf{f(x)\ is\ continuous}[/tex] [a,b] and

Then there is a point c in (a,b), such that: [tex]\mathbf{f'(c) = \frac{f(b) - f(a)}{b - a}}[/tex]
The function is given as:
[tex]\mathbf{f(x) = 3x^2 - 4x + 1}[/tex]
And the interval is: [tex]\mathbf{[0,2]}[/tex]
We have
[tex]\mathbf{f'(c) = \frac{f(b) - f(a)}{b - a}}[/tex]
This becomes
[tex]\mathbf{f'(c) = \frac{f(2) - f(0)}{2 - 0}}[/tex]

Calculate f(2) and f(0)
[tex]\mathbf{f(2) = 3\times 2^2 - 4\times 2 + 1 = 5}[/tex]
[tex]\mathbf{f(0) = 3\times 0^2 - 4\times 0 + 1 = 1}[/tex]
So, we have:

[tex]\mathbf{f'(c) = \frac{4}{2}}[/tex]
[tex]\mathbf{f'(c) = 2}[/tex]
Recall that:

Differentiate
[tex]\mathbf{f'(x)= 6x - 4}[/tex]
Substitute c for x
[tex]\mathbf{f'(c)= 6c - 4}[/tex]
Substitute 2 for f'(c)
[tex]\mathbf{ 6c - 4 = 2}[/tex]
Collect like terms
[tex]\mathbf{ 6c = 4 + 2}[/tex]
[tex]\mathbf{ 6c = 6}[/tex]
Divide both sides by 6

In the figure below, △ABC ~ △PQR. If the Area of △ABC is 40 cm2, what is the area of △PQR? show your work.
Answer:
90 square cm.
Step-by-step explanation:
For similar figures, the length of corresponding sides are proportional.
So we can write 4k = 6 where k is the proportionality constant.
Note: In terms of area, the scale factor would be k^2 and in terms of volume, it would be k^3y
Solving 4k = 6, we see that k = 6/4 or 3/2
We need area, so we multiply area of ABC by k^2 to get area of PQR.
[tex]40(\frac{3}{2})^2\\=40(\frac{9}{4})\\=90[/tex]
Area of PQR = 90 cm^2
Answer:
The area of △PQR is [tex]90\ cm^{2}[/tex]
Step-by-step explanation:
step 1
Find the scale factor
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
so
Let
z-----> the scale factor
x---> the corresponding side triangle PQR
y---> the corresponding side triangle ABC
[tex]z=\frac{x}{y}[/tex]
substitute the values
[tex]z=\frac{6}{4}=1.5[/tex]
step 2
Find the area of triangle PQR
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
so
Let
z-----> the scale factor
x---> the area of triangle PQR
y---> the area of triangle ABC
[tex]z^{2} =\frac{x}{y}[/tex]
we have
[tex]z=1.5[/tex]
[tex]y=40\ cm^{2}[/tex]
substitute the values
[tex]1.5^{2} =\frac{x}{40}[/tex]
[tex]x=40(1.5^{2})=90\ cm^{2}[/tex]

What is the probability (Image for It appears that people who are mildly obese are less active than leaner people. One study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes?
Answer:
0.0322; 0.9929
Step-by-step explanation:
Since the data is normally distributed, we use z scores for these probabilities.
The formula for a z score of a sample mean is
[tex]z=\frac{\bar{X}-\mu}{\sigma \div \sqrt{n}}[/tex]
For the sample of mildly obese people, the mean, μ, is 371; the standard deviation, σ, is 65; and the sample size, n, is 6.
Using 420 for X,
z = (420-371)/(65÷√6) = 49/(65÷2.4495) = 49/26.5360 ≈ 1.85
Using a z table, we see that the area under the curve to the left of this is 0.9678. However, we want the area to the right, so we subtract from 1:
1-0.9678 = 0.0322
For the sample of lean people, the mean, μ, is 528; the standard deviation, σ, is 108; the sample size, n, is 6.
Using 420 for X, we have
z = (420-528)/(108÷√6) = -108/(108÷2.4495) = -108/44.0906 ≈ -2.45
Using a z table, we see that the area under the curve to the left of this is 0.0071. We want the area under the curve to the right, so we subtract from 1:
1-0.0071 = 0.9929
The probability that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes is about 3.2%. For the 6 lean people, this probability is approximately 0.7%.
Explanation:For this type of problems, we use the concept of z-scores in statistics. The z-score is a measure of how many standard deviations a data point is from the mean. In this case, we will first calculate the standard error by dividing the standard deviation by the square root of sample size and then find the z-score by dividing the value of interest (420 minutes) minus mean by the standard error.
For mildly obese people, mean = 371 min, standard deviation = 65 min, sample size = 6. So, standard error = 65/sqrt(6) ≈26.51. The z-score for 420 min = (420-371)/ 26.51 ≈1.85. This indicates 420 minutes is 1.85 standard deviations above the mean. The probability that z-score exceeds 1.85 (assuming a one-tailed test since we are looking for the mean to be more than 420 minutes) is 0.032 (approximately). Hence, the probability that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes is about 0.032 or 3.2%.
For lean people, mean = 528 min, standard deviation = 108 min, sample size = 6. Using the same approach, standard error = 44.11. The z-score for 420 min = (420-528)/44.11 ≈-2.45. This indicates 420 minutes is 2.45 standard deviations below the mean. The probability that z-score is less than -2.45 (assuming a one-tailed test for under 420 minutes) will be more than 99%. The probability that z-score exceeds -2.45 (420 min or more time) is about 1 - 0.993 = 0.007. Hence, the probability that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes is about 0.007 or 0.7%.

P = (3.14)*(79 in) = 248.06 in
3) 1809 in
radius = 1809 in
P = 2*(3.14)*(1809 in) = 11360.52 in
diameter = 1809 in
P = (3.14)*(1809 in) = 5680.26 in
4) 152 in
radius = 152 in
P = 2*(3.14)*(152 in) = 954.56 in
diameter = 152 in
P = (3.14)*(152 in) = 477.28 in
Answer:

Step-by-step explanation:
As an estimation we are told ?3 is €4. Convert €83.60 to pounds. Give your answer rounded to 2 DP.
Answer:
€83.60 = £62.70
Step-by-step explanation:
£3/€4 = £x/€ 83.60
¾ = x/83.60
Multiply each side by the lowest common denominator (4 × 83.60)
3 × 83.60 = 4x
Divide each side by 4
x = (3 × 83.60)/4 = £62.70
∴ €83.60 = £62.70
(The conversion factor is out of date. The current conversion factor is closer to £6 = €7.)
Using the given exchange rate, we set up a conversion equation and solve for the unknown variable. We find that €83.60 is roughly equivalent to 62.86 pounds.
Explanation:Based on the given exchange rate, 1 pound (£) is equivalent to 1.33 Euros (€). Therefore, to convert €83.60 to pounds, we should do the following:
Set up the conversion ratio: 1.33 €/£ = 83.60 €/x £To solve for x (the value in pounds), cross-multiply: 1.33x = 83.60Divide both sides by 1.33: x = 83.60/1.33Rounding off to two decimal places, x = 62.86 £Therefore, €83.60 is approximately equivalent to 62.86 pounds.

Answer:
Just B and C
Step-by-step explanation:
Reduce this to the lowest amount possible.
log(3abc/6a^2b) = 2
=================
log(c/2a) = 2
c/2a = 10^2
c = 2a * 100
c = 200a
This one is also correct.
=================
The rest are just incorrect.
There is only 1 answer that works and that is B.
C is close, but it is not correct.
D is backwards. B is the right way and D is the upside down of B.
E and F are just not the way to handle logs. Subtracting logs means division, not multiplication and not 1 log.
=================
Please help, thanks a lot! :)
Match the stem and leaf plot to the correct set of data.
A.) 17, 17, 13, 28, 28, 26, 37, 35
B.) 7, 7, 3, 8, 8, 6, 7, 5
C.) 1.3, 1.7, 1.7, 2.6, 2.8, 2.8, 3.5, 3.7
D.) 1.3, 1.7, 1.7, 2.6, 2.8, 2.8, 3.5, 3.7, 3.7
Answer:
I believe the answer is A. 17, 17, 13, 28, 28, 26, 37, 35
The answer is C.
The stem, shows the number before the decimal point. The higher the number, the longer the stem goes down.
The leaf, shows the number after the decimal point. Each leaf is added to a row to match the stem of the original number.
1.3, 1.7, 1.7 all have a "1" before the decimal so they all go in the same row like this:
1 | 3 7 7
If we keep doing this, we see that C is the correct answer.

According to the Substitution Property of Equality: If y = -5 and 7x + y = 11, then _______ . Question 9 options: 7(-5) + y = 11 7x - 5 = 11 7x + 5 = 11 -5 + y = 11
Answer:
7x - 5 = 11
Step-by-step explanation:
To solve for x, substitute y = -5 into the equation 7x + y = 11.
This becomes 7x + (-5) = 11 or 7x - 5 = 11.
