Answer: 15%-8%=C

Step-by-step explanation:

Answer:

Well, you didnt include answers, but... here's the explanation.

Step-by-step explanation:

Ok so, the sale is 15% off.  As an example, lets use $10 as the original price.  15% off of $10 = 1.5, so we subtract 10 - 1.5 = 8.5.  Now, if the sale tax is 8%, we need to add 8% of 10, which is 0.8 - Now we get our final equation to calculate p, which is 8.5 + 0.8 = P.  8.5 + 0.8 = 9.3, and so the final price after discount AND sales tax are included is $9.3 - Hope this helped.  Mark me as brainliest please :)

Answer:

1) a. CI = 0.426 < p < 0.574

2) c. CI = 2.74% < p < 6.524%

3) a. CI = 20 < μ < 22

4) c. CI = 81.11 < μ < 85.09

5) b. CI = 76.21 < μ < 89.79

6) d. $453.59 < μ < $874.69

7) d. CI = $559 < σ < $1953.3

8) c. CI = $3.96 < σ < $6.72

9) c. 6.22 ft < σ < 12.59 ft

10) d. 0.19 oz < σ < 0.72 oz

Step-by-step explanation:

The Confidence Interval, CI are given as follows

For the population proportion

[tex]CI=\hat{p}\pm z\times \sqrt{\frac{\hat{p}(1-\hat{p})}{n}}[/tex]

1)  [tex]\hat p[/tex] = 55/110 = 0.5

z at 88% = ±1.56

a. CI = 0.426 < p < 0.574

2)  [tex]\hat p[/tex] = 31/669 = 0.5

z at 98% = ±2.326

c. CI = 2.74% < p < 6.524%

3) Here we have unknown population standard deviation, so we find the t interval

[tex]\bar x[/tex] = 21

n = 130

s = 3.0

Confidence level = 98%

[tex]CI=\bar{x}\pm t_{\alpha/2} \frac{s}{\sqrt{n}}[/tex]

[tex]t_{\alpha /2}[/tex] = ±2.356

CI = 20.380 < μ < 21.62

Rounding up gives;

a. CI = 20 < μ < 22

4) Similarly here we have;

[tex]t_{\alpha /2}[/tex] = ±1.699 and

c. CI = 81.11 < μ < 85.09

5) Here

[tex]\bar x[/tex] = 83

s = 13.5

n = 30

Confidence level = 99%

[tex]t_{\alpha /2}[/tex] = ±2.76 and

b. CI = 76.21 < μ < 89.79

6) In the question, we have

[tex]\bar x[/tex] = $664.14

s = $297.29

n = 14

Confidence level = 98%

[tex]t_{\alpha /2}[/tex] = ±2.65 and

CI = $453.56 < μ < $874.72

d. $453.59 < μ < $874.69

7) The confidence interval for a population standard deviation is given by the following relation;

[tex]\sqrt{\frac{\left (n-1 \right )s^{2}}{\chi _{1-\alpha /2}^{}}}< \sigma < \sqrt{\frac{\left (n-1 \right )s^{2}}{\chi _{\alpha /2}^{}}}[/tex]

Here

n = 9

x = $3959

s = $886

Therefore we have

d. CI = $559 < σ < $1953.3

8) Here we have;

n = 41

x = $108

s = $5

Therefore;

c. CI = $3.96 < σ < $6.72

9) Here we have;

n = 29

x = 65 ft

s = 8.5 ft

Therefore we have

CI = 6.3 ft < σ < 12.73 ft

c. 6.22 ft < σ < 12.59 ft

10) Here we have

n = 8

s = 0.301188123

d. 0.19 oz < σ < 0.72 oz.

Answer:

.25 or 25%

Step-by-step explanation:

.5 × .5 = .25 or 25%

Final answer:

The probability of at least two coins landing on heads can be found by calculating the probabilities for each possible number of heads (2 to 10), and adding them together, or by subtracting the probabilities of 0 or 1 head from 1. Each toss has a 50% chance, and binomial probabilities can be used for detailed calculations.

Explanation:

The question is about calculating the probability of at least two coins landing on heads when tossed multiple times. To solve this type of probability problem, one must consider all possible outcomes and then identify the number of favorable outcomes. Assuming each coin tossed is fair, the chance of landing on heads for any single toss is 50%.

Let's consider tossing a coin ten times. Theoretically, one could get an outcome with any number of heads ranging from 0 to 10. To specifically address the probability of getting at least two heads, you would add up the probabilities of getting 2 heads, 3 heads, ..., up to 10 heads. For example, the probability of getting exactly 2 heads in 4 tosses can be calculated using the binomial probability formula, which in this case would be P(X = 2) = (4 choose 2) * (0.5)^2 * (0.5)^(4-2), and you would perform similar calculations for each number of heads from 2 to 10.

The probabilities for getting 0 or 1 heads can be subtracted from 1 to find the probability of getting at least 2 heads. This approach is often easier than adding up all the individual probabilities for 2 to 10 heads. For instance, the probability of getting at least one (one or two) tail in two flips is P(F) = 3/4, where F is the event of getting at least one tail which includes the outcomes HT, TH, and TT.

Answer:

m = -1/2 and b = 2.5

Step-by-step explanation:

The slope intercept form of the equation of a line is

y = mx+b  where m is the slope and b is the y intercept

2.5 - 1/2x = y

Rewriting

y = -1/2x +2.5

The slope is -1/2 and the y intercept is 2.5

m = -1/2 and b = 2.5

Answer:

$2.54

Step-by-step explanation:

Tips are percentages of the meal prices.  Divide the tip by the meal price to find the percentage that the tip is of the meal.

9.20/78.00 = 0.118 = 11.8%

Multiply the second meal by the percentage calculated.

21.5 × 0.118 = 2.54

The tip for the second meal is $2.54

The equation x2 + 2x = 2x + x2 demonstrates the Commutative Property, showing that the order of addition does not change the result.

The equation x2 + 2x = 2x + x2 demonstrates the Commutative Property of addition. The Commutative Property states that for any numbers a and b, a + b = b + a. This property applies to both addition and multiplication, indicating that the order in which two numbers are added or multiplied does not change the result. In the given equation, the terms on both sides can be rearranged without changing the equality, showing that x2 + 2x is equal to 2x + x2 due to the commutative property.

Answer:

1350

Step-by-step explanation:

1000 to 1100 is an increase of 100 bacteria per 6 hours

100/6 = 16.67 bacteria per hour

16.67 * 15 hours = 250

Total bacteria should be 1100+250= 1350

hope this helps :D

Answer:

1,500 bacteria.

Step-by-step explanation:

I don't know what P=Aekt means but I understand the rest:

Hour 0: 1,000 bacteria

Hour 6: 1,300 bacteria

We can conclude from this evidence that it takes 6 hours to grow 300 new bacteria.

Let's use a ratio

new bacteria : hours

      300          :     6

        50          :      1

       500         :     10

So we get 500 new bacteria after 10 hours. Using our original population of 1,000 and our new added members, we get 1,500 bacteria at Hour 10.

Answer:

[tex] a =5[/tex]

Now we can use the info from the second point and we have:

[tex] 1280 = 5 b^8 [/tex]

We can divide 5 in both sides and we got:

[tex] 256 = b^8[/tex]

And using an exponent 1/8 in both sides we got:

[tex] (256)^{1/8} = b[/tex]

[tex] b = 2[/tex]

And then our model would be given:

[tex] y= 5 (2)^x [/tex]

Step-by-step explanation:

For this case we have two points given (0,5) and (8,1280). And we want to find a function given by this general expression:

[tex] y= ab^x [/tex]

And using the first point given we have:

[tex] 5 = a b^0 [/tex]

[tex] a =5[/tex]

Now we can use the info from the second point and we have:

[tex] 1280 = 5 b^8 [/tex]

We can divide 5 in both sides and we got:

[tex] 256 = b^8[/tex]

And using an exponent 1/8 in both sides we got:

[tex] (256)^{1/8} = b[/tex]

[tex] b = 2[/tex]

And then our model would be given:

[tex] y= 5 (2)^x [/tex]

Final answer:

To write an exponential function that passes through (0, 5) and (8, 1280), we first use the point (0, 5) to find that a = 5. Then, using the point (8, 1280), we solve for b, finding b = 2. Thus, the required exponential function is[tex]y = 5.2^x.[/tex]

Explanation:

To write an exponential function in the form y=ab^x that goes through the points (0, 5) and (8, 1280), we need to solve for a and b.

Step 1: Use the First Point (0, 5)

Substitute x = 0 and y = 5 into the equation:
5 = a · [tex]b^0[/tex]
Since any number raised to the power of 0 is 1, we find:
a = 5

Step 2: Use the Second Point (8, 1280)

Substitute x = 8, y = 1280, and a = 5 into the equation:
1280 = 5 ·[tex]b^8[/tex]
To solve for b, divide both sides by 5:
256 = [tex]b^8[/tex]

Finding the 8th root of both sides gives:
b = 2

Step 3: Write the Exponential Function

Now that we have a = 5 and b = 2, the exponential function is:
y = 5·[tex]2^x[/tex]

Answer:

The number of cubes needed = 12

Step-by-step explanation:

To know the number of cubes that will be needed to fill the prism, we need to divide the the volume of the right rectangular prism by the volume of the cube.

Mathematically, the volume of the right rectangular prism can be calculated using the formula;

V = whl

where w is the width, h is the height and l is the length.

Plugging the values we have in the question for the right rectangular prism, we have;

V = 3/4 * 1 * 1/4 = 3/16 inch^3

The volume of the cube can be calculated using the formula L^3 where L is the side length

V = 1/4 * 1/4 * 1/4 = 1/64 inch^3

The number of cubes needed to fill the prism is thus;

(3/16) ÷ (1/64) = 3/16 * 64/1 = 3 * 4 = 12

12 small cubes with side lengths of 1/4 inch each are needed to fill the given right rectangular prism.

To find out how many small cubes with side lengths of 1/4 inch are needed to fill a right rectangular prism with edges measuring 3/4 inch, 1 inch, and 1/4 inch, we need to calculate the volume of the prism and divide it by the volume of one small cube.

The volume of the prism is found by multiplying the lengths of its sides:
Volume of prism = (3/4 inch) * (1 inch) * (1/4 inch) = 3/16 cubic inches.

The volume of a small cube with a side length of 1/4 inch is:
Volume of small cube = [tex](1/4 inch)^3[/tex] = 1/64 cubic inches.

To find the number of small cubes needed to fill the prism, we divide the prism's volume by the small cube's volume:
Number of small cubes = Volume of prism / Volume of small cube
Number of small cubes = (3/16) / (1/64)

By simplifying this division, we get:
Number of small cubes = 3/16 * 64 = 12

Therefore, 12 small cubes with side lengths of 1/4 inch each are needed to fill the right rectangular prism.

Answer:.88

Step-by-step explanation:

Answer:

6

Step-by-step explanation:

Answer: c = 6

To solve for c in the equation you see here,

our goal is to get c by itself.

Our first step will be to isolate the term

containing c which in this problem is 3c.

To isolate 3c, we have to get rid of the +5 by

subtracting 5 from both sides of the equation.

On the left, the +5 and -5 cancel out

and we are simply left with 3c.

On the right, 23 - 5 simplifies to 18.

Now we have 3c = 18.

To get c by itself, since it's being multiplied by 3,

we just divide both sides of the equation by 3.

On the left, the 3's cancel and we are left with c.

On the right, 18/3 simplifies to 6.

So our answer is c = 6.
