Suppose SAT Writing score are normally distributed a mean of 497 and a standard deviation of 114. A university plans to admit students whose scores are in the top 30% . What is the minimum score required for admission? Round your answer to the nearest whole number.

Answers

Answer 1

Answer:

The minimum score required for admission to the nearest whole number = 557

Step-by-step explanation:

We solve this using z score formula.

z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

Top 30% of the candidates is a ranking that is equivalent to = 100 - 30% = 70th percentile.

The z score of 70th percentile = 0.524

Mean = 497

Standard deviation of 114.

Minimum score = raw score = ???

Hence:

0.524 = x - 497/114

Cross Multiply

0.524 × 114 = x - 497

59.736 = x - 497

x = 59.736 + 497

x = 556.736

The minimum score required for admission to the nearest whole number = 557

And what would the points be on a graph

Answers

the slope is -3 and the points would start at 6 which is the y intercept. you would plot a point at (0,6) then from there you would go up 3 and left one and continue this pattern. the line goes left because the slope is negative

On a keyboard, you can type 8^4*3^2 to indicate the same thing.

There are four copies of 8 being multiplied. Writing [tex]8^4[/tex] is a shorthand way of saying [tex]8 \times 8 \times 8 \times 8[/tex]. The exponent tells us how many copies of the base to multiply out.

Similarly, we have two copies of 3 which means [tex]3 \times 3 = 3^2[/tex]

Bill cut out 6 squares and 8 circles . He divided the cutouts into groups so that the same number of squares and circles were in each group. What is the greatest number of groups he could have made?

Answers

Step-by-step explanation

To find out how many groups can be made for 6 circles and 8 squares, start by finding what you can divide by both numbers.

                 6 can be divided by:                               8 can be divided by:

                                 1                                                                  1

                                 2                                                                 2

                                  3                                                                 4

                                  6                                                                 8

The greatest number that they both have in common is 2. There would be 3 circles and 4 squares if Bill divided into 2 groups.

what is the value of x in 5x−3(x−11)=7(2x−5)+2

Answers

The value of x is 5.5. I got this answer by first distributing -3 amongst (x-11), and distributing 7 amongst (2x-5). Next I combined like terms and subtracted 3x from 5x, and added -35 and 2. Next I subtracted 33 from both sides. Next I subtracted 14x from both sides. And finally I divided both sides by -12 to get the final answer of 5.5.

The distribution curve is skewed to the right.

Answers

Answer:

The correct option is;

The distribution curve is skewed to the right

Step-by-step explanation:

The given parameters are;

The mean = 58

The outlier = 92

Given that the outlier, P, can be found from the following formula, we have;

P > Q₃ + 1.5·IQR = (Q₃ + 1.5 (Q₃ - Q₁)

92 > (Q₃ + 1.5 (Q₃ - Q₁)

Given that mean = 58

Therefore, the IQR, and Q₃ are relatively small compared to the outlier, and the data is skewed, with the more smaller numbers than there are large numbers which makes the distribution curve to be skewed to the right.

Cindy runs 2 kilometers every morning. She takes 2 minutes for the first 250 meters, 4 minutes for the next 1,000 meters, 1 minute for the next 350 meters, and 3 minutes for the rest.
Cindy’s average speed for the entire run is ________
meters per minute. One kilometer is the same as 1,000 meters.

Answers

Answer:

286.1

Step-by-step explanation:

2 km = 2000 m

2 min = 250 m -> 125 m in 1 min

4 min = 1000 m -> 250 m in 1 min

1 min = 350 m -> 350 m in 1 min

3 min = 400 m (the rest) -> 133.33 m in 1 min

To get the average you add up all 3 and divide by 3

So: 125 + 250 + 350 + 133.33 = 858.33

858.33/3 = 286.11

So rounded its 286.1
