Answer:

0.54035

Step-by-step explanation:

Given that :

Mean, m = 66 inches

Standard deviation, s = 2.5 inches

P(65 < X < 69)

P(X < 69) - P(X < 65)

((69 - 66) / 2.5) - ((65 - 66) / 2.5)

P(Z <(3/ 2.5)) - P(Z <(-1 / 2.5))

P(Z < 1.2) - P(Z < - 0.4)

0.88493 - 0.34458

= 0.54035

I need help on number 9. I don’t even know how to start
Elan Coil [88]

begin by pulling 2 out of the numerator using the distributive property.

numerator: 2(16x^4 - 25)              and now factor

numerator: 2(4x^2 - 5)(4x^2 + 5)

Now go to the denominator. It looks messy but it will break down.

Pull out 4x^2 for the first two terms and 5 for the last 2 terms. Use the distributive property.

denominator: 4x^2(x - 3) - 5(x - 3)  now x - 3 is the common term.

denominator: (x - 3)(4x^2 - 5)

Put the two results together.

\dfrac{2(4x^2- 5)*(4x^2+5)}{(4x^2-5)(x-3)}

After canceling out 4x^2 - 5 on both the numerator and the denominator, you are left with.

\dfrac{2(4x^2+5)}{(x-3)}

5. The internal dimension of a tank are 14m, 8m and 5m. How much water can be
EleoNora [17]

Answer:

560,000L

Step-by-step explanation:

Given data

L=14m

W=8m

H=5m

Volume= L*W*H

Volume= 14*8*5

Volume= 560 m^3

1m^3 = 1000L

560m^3 = x

cross multiply

x= 560*1000

x= 560,000L

Hence the volume is  560,000L
