The area between z= -2.31 and z= 0.47

SAT
1 answer:
siniylev [52]3 years ago
5 0

Answer:

0.67038

Explanation:

One z-value is negative and the other is positive.

This means we are looking for area between the two given z-values on opposite sides of the mean.

From z-table attached, the area at z = -2.31 is 0.98956

Also, from the second z-table attached, the area at z = 0.47 is 0.68082

But since we are looking for the area between both z-scores, we will now have;

P(-2.31 < x < 0.47) = (0.98956 + 0.68082) - 1

P(-2.31 < x < 0.47) = 0.67038

If 5b=6a+16 and 9a=7b-20, then what is the value of 3a-2b?<br> A) -8<br> B) -4<br> C) 4<br> D) 8
vovangra [49]
B) -4
5b=6a+16
9a=7b-20
b=(6/5)a+(16/5)
9a=7((6/5)a+(16/5))-20
9a=(42/5)a+12/5
(3/5)a=12/5
a=4
5b=6(4)+16
5b=24+16
5b=40
b=8
3(4)-2(8)
12-16=-4

At a football game, the ratio of filled seats to empty seats was 7 to 3. The capacity of the stadium is 70,580. How many seats w
UkoKoshka [18]

The number of seats in the stadium that were filled for the game is equal to 49,406 seats.

  • Let the filled seats be F.
  • Let the empty seats be E.

<u>Given the following data:</u>

  • Stadium capacity = 70,580.
  • Ratio of F to E = 7:3
  • Total ratio= 7 + 3 = 10

To determine the number of seats in the stadium that were filled for the game:

Mathematically, the number of filled seats in the stadium is given by this expression:

F = \frac{7}{10} \times 70580\\\\F=0.7 \times 70580

F = 49,406 seats.
