If x= -8 and y=-4, evaluate the expression.<br> <img src="https://tex.z-dn.net/?f=%5Cfrac%7B3x-4%7D%7By-3%7D" id="TexFormula1"

bagirrra123 [75]

Your answer would be 4.

If we substitute in x = -8 and y = -4 into the expression, we get:

$\frac{3(-8) - 4}{-4 - 3}$

This then becomes:

$\frac{-24 - 4}{-7}$ = $\frac{-28}{-7}$ = 4.

I hope this helps!

Suppose you draw a single sample of size 64 from a large population and measure its sample proportion. What is the margin of err

MissTica

Answer:

(b) 6.25%

Step-by-step explanation:

Margin of error is the chances of percentage deviation that may differ from original population data. The margin of error for 95% confidence interval can be 6.25%. To find this we divide population standard deviation with square root of sample size. The margin of error is the estimate of the deviation from actual and real value of population.

Delvig [45]

Answer:

The value of tan P = 1.875

Step-by-step explanation:

Given:

PR=17

RQ=15

PQ =8

To find:

tan P = ?

Solution:

In trigonometric ratio

tan = $\frac{opposite}{adjacent}$

Now on substituting the given values(refer the figure)
