74% of freshmen entering public high schools in 2006 graduated with their class in 2010. A random sample of 81 freshmen is selec

Assoli18 [71]

Answer: Probability that the proportion of students who graduated is greater than 0.743 is P = 0.4755

Step-by-step explanation:

Given that,

Probability of freshmen entering public high schools in 2006 graduated with their class in 2010, p = 0.74

Random sample of freshman, n = 81

Utilizing central limit theorem,

$P(\hat{p}$

So,

$(P(\hat{p}>0.743) = P(Z>0.743 - \frac{0.74}{\sqrt{\frac{0.74(1-0.74)}{81} } } )$

= P( Z > 0.0616)

= 0.4755 ⇒ probability that the proportion of students who graduated is greater than 0.743.

Pierce draws a circle with a radius of 3 centimeters. Ginna draws a circle with a radius that is twice as long as the radius of

erastova [34]

Answer:

Circumference of the circle drawn by Ginna is twice the Circumference of the circle drawn by Pierce.

Step-by-step explanation:

Given:

Radius of the circle drawn by Pierce = 3 cm

We need to find circumference of gianna's circle compare with the circumference of Pierce's circle.

Solution:

Radius of the circle drawn by Pierce = 3 cm

so we will find the Circumference of circle drawn by Pierce.

Now we know that;

Circumference of the circle is given by 2 times π times radius of the circle.

framing in equation form we get;

Circumference of the circle drawn by Pierce = $2\pi\times 3=6\pi\ cm$

Now Given:

Ginna draws a circle with a radius that is twice as long as the radius of pierce's circle.

So we can say that;

radius of the circle drawn by Ginna is equal to 2 times radius of circle drawn.

so we can say that;

radius of the circle drawn by Ginna = $2\times3 = 6\ cm$

Circumference of the circle drawn by Ginna = $2\pi\times 6=12\pi\ cm$

Now we can see that;

Circumference of the circle drawn by Ginna is $12\pi \ cm$ while Circumference of the circle drawn by Pierce is $6\pi \ cm$

So we can say that;

Circumference of the circle drawn by Ginna is twice the Circumference of the circle drawn by Pierce.

Of five letters (A, B, C, D, and E), two letters are to be selected at random. How many possible selections are there?

taurus [48]

Answer: d. 10

Step-by-step explanation:

We know that the number of combinations of r objects selected from a group of n objects at a time is given by :-

$^nC_r=\dfrac{n!}{(n-r)!r!}$

Given : The total number of letters = 5

The number of letters need to select = 2

Then , the number of combinations of 2 letters selected from a group of 5 letters at a time is given by :-

$^5C_2=\dfrac{5!}{(5-2)!2!}=\dfrac{5\times4\times3!}{3!\times2}=10$

Hence, there are 10 possible selections.
