There are two major tests of readiness for college: the act and the sat. act scores are reported on a scale from 1 to 36. the di
Olin [163]

Solution: We are given:

ACT scores follow normal distribution with \mu=20.9,\sigma =4.8

SAT scores follow normal distribution with \mu=1026,\sigma=209

Now, let's find the z score corresponding to Joe's SAT score 1351.

z=\frac{x-\mu}{\sigma}

        =\frac{1351-1026}{209}

        =\frac{325}{209}

        =1.56

Therefore, Joe's SAT score is 1.56 standard deviations above the mean.

Now, we have find the Joe's ACT score, which will be 1.56 standard deviations above the mean.

Therefore, we have:

z=\frac{x-\mu}{\sigma}

1.56=\frac{x-20.9}{4.8}

1.56 \times 4.8 = x - 20.9

7.488=x-20.9

x=20.9+7.488

x=28.388 \approx 28.4

Therefore, Joe's equivalent ACT score to SAT score 1351 is 28.4

What is the volume of the right prism with height h=14 cm, if the base of the prism is a triangle ∆ABC with side AB = 9 cm and a
Lina20 [59]
<u><em>Answer:</em></u>
volume of prism = 378 cm³

<u><em>Explanation:</em></u>
<u>The volume of the right prism can be calculated as follows:</u>
volume of prism = area of base * height of prism

<u>1- getting the area of base:</u>
Our base is a triangle, this means that:
area = 0.5 * base * height
We have:
base = 9 cm
height = 6 cm
Therefore:
area of base = 0.5 * 9 * 6
area of base = 27 cm²

<u>2- getting the volume:</u>
volume of prism = area of base * height of prism
volume of prism = 27 * 14
volume of prism = 378 cm³

Hope this helps :)

P(A) = 7/20 P(B) = 7/20 P(A or B) = 49/80, P(A and B)= ?​
OverLord2011 [107]

Answer:

P(A and B) = 7/80

Step-by-step explanation:

The given values of the probabilities of the different events are;

P(A) = 7/20

P(B) = 7/20

P(A or B) = 49/80

P(A and B) = Required

We have by probability theory for any event;

P(A or B) = P(A) + P(B) - P(A and B)

Therefore;

P(A and B) = P(A) + P(B) - P(A or B)

Plugging in the values gives;

P(A and B) = 7/20 + 7/20 - 49/80 = 7/80

∴ P(A and B) = 7/80
