Answer:
The minimum score required for admission is 558.75.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score 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. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Suppose SAT Critical Reading scores are normally distributed with a mean of 501 and a standard deviation of 110.
This means that [tex]\mu = 501, \sigma = 110[/tex]
A university plans to admit students whose scores are in the top 30%. What is the minimum score required for admission
This is the 100 - 30 = 70th percentile, which is X when Z has a pvalue of 0.7. So X when Z = 0.525. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.525 = \frac{X - 501}{110}[/tex]
[tex]X - 501 = 0.525*110[/tex]
[tex]X = 558.75[/tex]
The minimum score required for admission is 558.75.

Answer:
option 2
Step-by-step explanation:
Answer:
-2 2/3, -2.5, 1.3, 1 1/2, 3
Step-by-step explanation:
So least to greatest
First we should look at the negatives
The smallest number is -2 2/3
The second smallest number is -2.5
The third smallest number is 1.3
The fourth smallest number is 1 1/2
The last number should be the biggest number which would be 3 in this problem
To make this easier you can convert all the fraction to decimal points too
-2 2/3 would be around -2.66
1 1/2 would be 1.5

Step-by-step explanation:
. If a student is randomly choosing the answer to each of ten true-false questions in a test, what is the probability that he will have at most one incorrect answer (express the answer with four decimal places)
Answer:
0.0107
Step-by-step explanation:
Given that:
Probability of success in choosing a true - false answer :
(Number of correct answers / number of options)
= 1/2 ; p = 0.5
Number of questions = number of trials, n = 10
Probability of having atmost one incorrect answer :
p(incorrect answer) = 0.5
P(x ≤ 1) = p(0) + p(1)
Using binomial distribution formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
When x = 0
P(x = 0) = 10C0 * 0.5^0 * 0.5^10
P(x = 0) = 1 * 1 * 0.0009765625
P(x = 0) = 0.0009765625
When x = 1
P(x = 1) = 10C1 * 0.5^1 * 0.5^9
P(x = 1) = 10 * 0.5 * 0.001953125
P(x = 0) = 0.009765625
P(x ≤ 1) = 0.0009765625 + 0.009765625
P(x ≤ 1) = 0.0107421875

The circumference of a circle is 6π ft. What is the area, in square feet? Express your answer in terms of
π
Please help
Answer:
Circumference of the circle 2π(radius)=6π ft
Therefore, radius=3 ft
Area=π(radius)²=π×3²=9π ft²
9π ft² is the right answer.
The area of circle is 9π square feet.
What is area?Area is the amount of area occupied by an object's flat (2-D) surface or shape.
The circumference of circle = 2πr
6 = 2πr
r = 3π
And the area of circle is πr².
The area of the circle = 9π
Therefore, the area of the circle is 9π square feet.

Let N be the number of data entries in a population and n be the number of data entries in a sample data set. Describe the difference between the calculation of population standard deviation and sample standard deviation.
Answer:
Step-by-step explanation:
During the calculation of any population standard deviation, the sum of the squared deviation is usually divided by N, which is the number of data entry in the population. Thereafter, the square root of the result would be taken.
On the other hand, during the calculation of the sample standard deviation, the sum of the squared deviations is usually divided by n - 1, with n being number of entries in the sample data set. Thereafter, the square root of the result would be taken.

i accidentally answered this one instead of another one sorry
Steven has five times more tickets than Jared.
What is Multiplication?'Multiplication is an operation that represents the basic idea of repeated addition of the same number.'
According to the given problem,
If we add the number of tickets till it equals Steven's number of tickets,
= 4 + 4 + 4 + 4 + 4
= 20
