Answer:

margo's pay was $96 dollars

Step-by-step explanation:

Let 'x' represent the amount of Margo's paycheck.  Since she spent 0.25 on a dress, 1/8 (0.125) on shoes and another $24 on a present for a total of $60, we can set up the following equation:

0.25x + 0.125x + 24 = 60

Combine like terms:  0.375x + 24 = 60

Subtract 24 from both sides: 0.375x + 24 - 24 = 60-24 or 0.375x = 36

Divide by 0.375: 0.375x/0.375 = 36/0.375

Solve for x: x = $96

Answer:

$96

Step-by-step explanation:

Use the answer choices and test each one

If you test $96 for the paycheck, it works

96/4 = 24

96/8 = 12

24 + 12 = 36

36 + 24 = 60

This option is right because she spent $60 total

A set of data is normally distributed with a mean of 327 and a standard deviation of 27.
d1i1m1o1n [39]

Answer:

  86.7%

Step-by-step explanation:

For questions regarding values related to a normal distribution, a suitable calculator is required. Numerous calculators, apps, web sites, and spreadsheets are capable of answering this question.

__

One standard deviation above the mean is 327 +27 = 354, so the value is expected to be slightly more than 50% +34% = 84%. It is no surprise, then, that a calculator tells you 86.7% of the data is below 857.

_____

<em>Additional comment</em>

The "empirical rule" tells you 68% of the area is within 1 standard deviation of the mean. The distribution is symmetrical, so half that, 34%, is between the mean and 1 standard deviation above the mean. Of course, 50% of the data is below the mean.

A red die is tossed and then a green die is tossed. What is the probability that the red die shows a number larger than three or
lianna [129]

Answer:

Red: 67%

Green: 33%

Step-by-step explanation:

Since each die has 6 sides, there is a 1/6 chance for every number.

Probability for a number higher than 3 would be 4/6, which is about 67%.

Probability for below 3 would be 2/6, which is about 33%.


I am not 100% sure, but I hope this helps you.

According to the Behavioral Risk Factor Surveillance System, 58% of all Americans adhere to a sedentary lifestyle (sedentary mea
sammy [17]

Answer:

Step-by-step explanation:

Hello!

The variable is X: number of sedentary people in a sample of 12.

This is a discrete variable with a binomial distribution and the probability of success is p=0.58. To determine if a variable has or not a binomial distribution you have to see if it follows the binomial criteria:

Binomial criteria:

1. The number of observation of the trial is fixed n=12

2. Each observation in the trial is independent, this means that none of the trials will affect the probability of the next trial. The activity habits on each person are independent of the others.

3. The probability of success in the same from one trial to another p=0.58

So X≈ Bi (n;ρ)

a. If you were to take a sample of n=12.

The expected value (mean) is E(X)= n*p= 0.58*12= 6.96

And the Standard deviation:

V(X)= n*p*q= 12*0.58*(1-0.58)= 2.92

√V(X)= 1.71

b. I'll calculate the probability of exactly 10 persons having sedentary habits using the table of cumulative probabilities, to do so, you have to look for the accumulated probability until 10 and subtract the accumulative probability until 9:

P(X=10) = P(X≤10) - P(X≤9)= 0.9859 - 0.9358= 0.050

I hope you have a SUPER day!
