A manufacturer produces widgets that are packaged in boxes of 100. The probability of a widget being defective is 0.021. Find th

gavmur [86]

Answer:

$\=x=2.1$

$\sigma=2.03$

Step-by-step explanation:

From the question we are told that:

Sample size $n=100$

Probability of a defective widget $P=0.021$

Generally the equation for binomial trial is mathematically given by

$q=1-p$

$q=1-0.021$

$q=0.979$

Since X is binomial random variable with functions of n and p,The equation of mean \=x

$\=x=E(x)$

Where

$E(x=n*p)$

$\=x=100*0.021$

$\=x=2.1$

Generally the equation for variance \sigma is mathematically given by

$\sigma=\sqrt{nqp}$

$\sigma=\sqrt{200*0.021*0.979}$

$\sigma=2.03$

Find the range of y = 3/2 cos 4x - 1

motikmotik

Answer:

B. $-2\frac{1}{2} \leq y \leq \frac{1}{2}$

Step-by-step explanation:

The given trigonometric function is

$f(x)=\frac{3}{2}cos4x-1$ .

The amplitude of this function is $\frac{3}{2}$ , so under normal circumstances the range is supposed to be

$-\frac{3}{2} \leq y \leq \frac{3}{2}$

But the $-1$ is a downward vertical shift.

Therefore the normal boundaries of the range will shift down one unit to give the range of the transformed function.

We subtract 1 from the lower boundary to get $-\frac{3}{2}-1=-2\frac{1}{2}$

We also subtract 1 from the upper boundary to get $-frac{3}{2}-1=\frac{1}{2}$

Hence the range is

$-2\frac{1}{2} \leq y \leq \frac{1}{2}$
