Answer:

AC=12.2\ units

Step-by-step explanation:

we know that

In the right triangle ABC

sin(70\°)=\frac{AC}{AB}

Solve for AC

AC=ABsin(70\°)

substitute the values

AC=13(0.9397)=12.2\ units

Answer:

y = 50x

Step-by-step explanation:

the equation for this is y = 50x because for every 50 units we go up by on the graph we go 1 unit to the right so:

slope-intercept form: y = mx + b   where m is the slope and b is the y-intercept. Our y-intercept is 0 because that is where our line intersects the y-axis and because it is 0 we do not need to put it in the equation.

y = 50x

Stels [109]

Answer:

The appropriate response is "0.9476".

Step-by-step explanation:

The given values are:

Standard deviation,

\sigma=1150

Randomly selected railroad-car shipments,

n = 500

As we know,

⇒ \sigma \bar{x}=\frac{\sigma}{\sqrt{n} }

On substituting the values, we get

⇒      =\frac{1150}{\sqrt{500} }

then,

⇒      =P(-1.94

⇒      =P(Z

On using the table of P, we get

⇒      =0.9738 - 0.0262

⇒      =0.9476
