Answer:

The answer is D

Step-by-step explanation: I solved by subsitution and found y=2x-15 So therefore 2x+4(2x-15)=10 and then x=7 and that was the only answer with7 as x but to check I did y=2(7)-15 and y=-1

F(x) = x^2+1 and g(x) = x-4 <br> (f/g)(5)=
Nezavi [6.7K]

The value of the composite function is (f/g)(5)= 26

<h3>How to evaluate the composite function?</h3>

The functions are given as:

f(x) = x^2+1 and g(x) = x-4

To calculate the composite function, we use the following formula

(f/g)(x)= f(x)/g(x)

So, we have:

(f/g)(5)= f(5)/g(5)

Calculate f(5) and g(5)

f(5) = 5^2+1 and g(5) = 5-4

This gives

f(5) = 26 and g(5) = 1

Substitute f(5) = 26 and g(5) = 1 in (f/g)(5)= f(5)/g(5)

(f/g)(5)= 26/1

Evaluate

(f/g)(5)= 26

Hence, the value of the composite function is (f/g)(5)= 26

If the random variable X is normally distributed with a mean of 75 and a standard deviation of 8, then P(X ≥ 75) is:a. 0.500b. 0
drek231 [11]

Answer:

a. 0.5

Step-by-step explanation:

We know that X follows normal distribution with

mean=75

standard deviation=8

P(X\geq 75)=P(\frac{x-mean}{standard deviation}\geq \frac{75-75}{8})

P(X\geq 75)=P(Z\geq 0)

P(Z\geq 0)=P(0<Z<∞)

The area under the normal curve is 1 and the  (0<Z<∞) =0.5 and (-∞<Z<0) =0.5

So, P(0<Z<∞)=0.5

Hence the P(X ≥ 75)=0.5
