A random sample of bolts is taken from inventory, and their lengths are measured. The average length in the sample is 5.3 inches

LekaFEV [45]

Answer:

$L_x=5.3 inches$

Step-by-step explanation:

Average length $\=x =5.3 inches$

Standard deviation $\sigma=0.2 inches$

Sample size $n=50$

Generally The point estimate for the mean length of all bolts in inventory is

$L_x= \=x$

$L_x=5.3 inches$

Jerry’s loan had a principal of $22,000. He made quarterly payments of $640 for nine years until the loan was paid in full. How

Leto [7]

Answer: $1040

A = P + I

A = Total

P = Principal

I = Interest

First find the total amount

A = 640(4)(9)

A = 23040

Plug In the Numbers

23040 = 22000 + I

Substract 22000 on both sides

I = $1040

Which inequality is represented by the graph?y > -2/3x + 1y < -2/3x + 1y < -3/2x + 1y > -3/2x + 1

Tanya [424]

Answer:

$y < -\frac{3}{2}x+1$

Step-by-step explanation:

Given:

From the graph shown,

The broken line means that the inequality sign will be either < or >.

The shaded region is to the left of the broken line. This means that $y < f(x)$ .

Now, in order to find equation of line, we need slope and y-intercept.

From the graph, the y intercept is at $(0,1)$ . So, y intercept is 1.

Also, if we consider two points $(0,1)\textrm{ and }(2,-2)$ on the line, then slope is given as:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{-2-1}{2-0}=\frac{-3}{2}=-\frac{3}{2}$

Therefore, the equation of the line is given as:

$y=mx+b\\y=-\frac{3}{2}x+1$

But as the shaded region is to the left of the line,

∴ $y$ is the correct answer.
