Which function represents a reflection of f(x) = 3/8 (4)x across the y-axis?
almond37 [142]

Answer:

D is correct option.g(x)=\frac{3}{8}\cdot (4)^{-x}

Step-by-step explanation:

We are given a function f(x)=\frac{3}{8}\cdot (4)^x

We need to find new function reflection of f(x) across the y-axis.

When function reflection across y-axis x\rightarrow -x

\text{Reflection across y-axis}f(x)\rightarrow f(-x)

Therefore, f(-x)=\frac{3}{8}\cdot (4)^{-x}

New function, g(x)=f(-x)

g(x)=\frac{3}{8}\cdot (4)^{-x}

Thus, D is correct option.

A test to measure psychotic tendencies was given to a group of 1,000 air force cadets who wished to work in nuclear silos. Any c
Anastaziya [24]

Answer:

Option d) 840

Step-by-step explanation:

Given that a test to measure psychotic tendencies was given to a group of 1,000 air force cadets who wished to work in nuclear silos.

If Score ≥64 would be eliminated.

X is N(52, 12)

Probability for any random person to get eliminated

=P(X\geq 64)\\= 1-R(64)\\=1-0.8413\\= 0.1587

Now coming to sample size of 1000 people, we find each person is independent of the other and there are two outcomes either >64 or < 64

So Y no of persons who get more than 64 is binomial with n =1000 and p = 0.1587

Mean of Y = E(Y)

= no of people who were not accepted =1000(0.1587) = 158.7

No of people accepted = 1000-158.7 = 841.3\\=841

Approximately we get 840 so option d
