Answer:

<h3>The answer is - 3</h3>

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

$m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\$

From the question we have

$m = \frac{8 - 5}{ - 8 - - 7} = \frac{3}{ - 8 +7 } = - \frac{3}{1} = - 3 \\$

We have the final answer as

Answer:

The length of BC is 17 units

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal angles

In this problem we have an isosceles triangle

Because

m∠ACB=m∠ABC ----> given problem

AC=AB

substitute the given values

$x+9=2x-8$

solve for x

$2x-x=9+8$

$x=17$

therefore

The length of BC is 17 units

9. Stan’s Deli is situated inside a large industrial park. The weekday gross sales at Stan’s average $1,240, with a standard dev

mr Goodwill [35]

Answer:

0.9792

Step-by-step explanation:

Data provided in the question:

Average gross sales = $1,240

Standard deviation = $180

sample size = 40

Now,

standard deviation of sample average

= $\frac{\textup{Standard deviation}}{\sqrt{n}}$

= $\frac{180}{\sqrt{40}}$

= 28.46

Now,

z value for 1200 = $\frac{(1200-1240)}{28.46}$ = -1.4,

and,

p value for (z = -1.4) = 0.0808

therefore,

P(average < $1200) = 0.0808

Thus,

probability that the average over the next 40 weekdays will exceed $1,200

= 1 - 0.808

= 0.9792

According to the rational root theorem, which is a factor of the polynomial

vekshin1

Supposing 2x-7 were a factor, then 7/2 would be a root. Use synth. div. to determine whether 7/2 actually is a root:

__________________________
7/2 / 6 -21 -4 24 -35
21 0 -14 35
----------------------------------------
6 0 -4 10 0

Since the remainder is zero, 7/2 is a root and 2x - 7 is a factor.

You could check out the other possible factors in the same manner.
