The fractions that are equivalent to 40% are 4/10 and 8/20

Fractions are written as a ratio of two integers

Given the percentage 40%

Write as a fraction

40% = 40/100

Divide through by 4

40% = 40/100 = 4/10

Multiply both numerator and denominator by 2

4/10 * 2/2 = 8/20

Hence the fractions that are equivalent to 40% are 4/10 and 8/20

The correct answer is the last on that’s states: it is not a valid sample because it is not a random sample of the population.

Step-by-step explanation:

When a researcher wants to know about the same thing, he/she has to take a sample from the population.

Example, consider a researcher wants to know how many hours the students study at home in a week, so the researcher has to take the sample from the student population.

Here, he/she gives the advertisement and offers $10 for 10 people. Therefore for anyone can come they might not required for a particular study.

Answer:

E

Step-by-step explanation:

To find the sum, you most find the answers for both powers of tens. 10^2 is 100, so 4.9*100=490. 10^3 is 1000, so 6.8^1000= 6800. Add them together and you get 7290, which if divided by 1000, you get 7.29. Since 10^3 is 1000, the correct answer isE.

Step-by-step explanation:

The transformation is proved through comparing the size of the bigger triangle to the smaller triangle in the individual sides. So the size of A F/ AB should be equal to AG / AC due to transformations making A F and AG the same times longer as AC and AB. By performing those calculations, you get 3.

Answer: 562.5

Step-by-step explanation:

Ok...Im PRETTY sure this is right, because you multiply 5 (5 years till 2025) times 7.5 (the rate of decrease in price) and subtract that from 500, so that would be 600-37.5, which gives you 562.5

Okay, so the formula for these types of problems is [tex]yab^x[/tex] I believe, or something like that.

So the price is 600 for y, 1-0.0075 is the b because it is decreasing in value each year, and it is 5 years from now, so 5 for the x.

Plug those in, and you will get about 577.83.

I hope this helps.

The product of (3 – 2i) and (3 + 2i) simplifies to 13 after expanding and simplifying the expression, canceling out the imaginary terms.

To find the product of (3 – 2i) and (3 + 2i), we'll use the distributive property:

(3 - 2i)(3 + 2i) = 3(3) + 3(2i) - 2i(3) - 2i(2i)

                = 9 + 6i - 6i - 4i²

Since i² = -1, substitute -1 for i²:

= 9 + 6i - 6i - 4(-1)

= 9 + 6i - 6i + 4

The terms with imaginary parts cancel out:

= 9 + 4

= 13

Thus, the product of (3 – 2i) and (3 + 2i) equals 13.

Final answer:

To find the probability of a ship coming ashore in a given state, divide the length of its shoreline by the total length of the Gulf of Mexico's shoreline.

Explanation:

To find the probability of a ship coming ashore at a random point in the Gulf of Mexico landing in a given state, we need to divide the length of the shoreline of that state by the total length of the Gulf of Mexico's shoreline. Let's assume there are 4 states that border the Gulf of Mexico: State A with 100 miles of shoreline, State B with 150 miles, State C with 200 miles, and State D with 250 miles. The total shoreline length of the Gulf of Mexico would be 700 miles (100 + 150 + 200 + 250).

Now, we can find the probability for each state by dividing its shoreline length by the total shoreline length. For example, for State A, the probability would be 100/700 which is approximately 0.1429 or 14.29%.

Following the same calculation, the probability for State B is 150/700 which is approximately 0.2143 or 21.43%, the probability for State C is 200/700 which is approximately  0.2857 or 28.57%, and the probability for State D is 250/700 which is approximately 0.3571 or 35.71%.

Answer:

(a)Mean=14

(b)Median=14.5

Step-by-step explanation:

Given the data set:

5,5, 9, 10, 13, 16, 18, 20, 22, 22​

(a)Mean

[tex]\bar{x}=\dfrac{5+5+9+10+13+16+18+20+22+22}{10} \\=\dfrac{140}{10} \\Mean=14[/tex]

(b)5,5, 9, 10, 13, 16, 18, 20, 22, 22​

Since we have two terms in the middle, we take the average to obtain the median.

Median

[tex]=\frac{13+16}{2}\\=\frac{29}{2}\\Median=14.5[/tex]

Answer:

The amount financed under this mortgage is $185,600

Step-by-step explanation:

Alice took out an 80/20 mortgage on a $232,000 home.

80/20 mortgage means pay 20% down payment and 80% finance amount of home value.

Home value = $232,000

Now, we need to find finance amount from this hone value of $232,000

Let's calculate the 80% of $232,000 as finance amount;

Finance amount = 80% of 232000

 Finance amount  = 0.80 x 232000

Finance amount = 185,600

Hence, The amount financed under this mortgage is $185,600

Answer:

Which of the following is true if the data point 11.1 is corrected to 11.7?

A.The mean increases.

B.The median increases.

C.The data set has two modes.

D.The range increases.

A.The mean increases.

C.The data set has two modes.

These are the correct answers.

A and C will be correct answers.

The average of a group of variables is referred to as the mean in mathematics and statistics. There are several methods for calculating the mean, including basic arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means.

Given that the Data point is corrected from 11.1 to 11.7. As we already know if we increase the value of the data point the mean will rise when a data point is added that is above the mean or subtracted that is below the mean. The mean will drop if one or more data points are removed that are above the mean or added that are below the mean.

Therefore, If data point 1.1 is corrected to 11.7 then the mean will increase and the data set has two modes.

Answer:

0.6968 L

Step-by-step explanation:

We can calculate the resulting volume thanks to Boyle's Law, which tells us The volume is inversely proportional to the pressure:

• If the pressure increases, the volume decreases.

• If the pressure decreases, the volume increases.

Thus:

P1V1 = P2V2

We know that P1 = 12 atm, V1 = 0.0871 L and P2 = 1.5 atm, that is, the value that we do not know about V2, therefore we solve for V2:

V2 = P1V1 / P2

Replacing:

V2 = 12 * 0.0871 /1.5

V2 = 0.6968 L

Which makes sense, since decreasing the pressure increases the volume.

Answer:3

Step-by-step explanation:

This is the basic definition of an inverse. f(3)=-15 means you plugged in 3 in the function, and you ended up with -15. The inverse means you plugged in some number x, and ended up with -15. Because f(3)=-15, the answer is 3.

Answer:

The critical z value used to test a null hypothesis is ±1.75.

Step-by-step explanation:

We are given that the data has a normal distribution and the number of observations is greater than fifty.

Also, the hypothesis given to us is;

Null Hypothesis, [tex]H_0[/tex] : [tex]\mu[/tex] = 3.24

Alternate Hypothesis, [tex]H_1[/tex] : [tex]\mu\neq[/tex] 3.24

This means that our test is two-tailed because in the alternate hypothesis we are concerned with mean value is less than or greater than 3.24.

Also, level of significance (α) = 0.08

Now, for two-tailed test level of significance becomes =  [tex]\frac{\alpha}{2} =\frac{0.08}{2}[/tex] = 0.04

So, in the z-table the critical value of x at 4% significance level is given as 1.75.

Since, this is two-tailed test so the critical z value used to test a null hypothesis would be ±1.75.

At the 4% significance level, the z-value is 1.75. Therefore, for the two tailed test the z value becomes [tex]\pm[/tex] 1.75. and this can be determined by using the given data.

Given :

According to the hypothesis test:

Null Hypothesis  --  [tex]\rm H_0:\mu=3.24[/tex]

Alternate Hypothesis  --  [tex]\rm H_1 : \mu\neq 3.24[/tex]

According to the given data, the significance level is given by ​α = 0.08. So, the significance level for the two tailed test is given by:

[tex]\rm \dfrac{\alpha }{2}=\dfrac{0.08}{2}=0.04[/tex]

So, for the 4% significance level, the z-value is 1.75. Therefore, for the two tailed test the z value becomes [tex]\pm[/tex] 1.75.

So, the correct option is a).
