In any given week, salesman A earns $65 per sale, so his paycheck amounts to $p_A(s)=65s$ (where $0\le s\le20$ ).

Salesman B earns $40 per sale, with a weekly salary of $300, so in any given week this salesman earns $p_B(s)=45s+300$ .

Salesman C earns a flat rate of $900 per week regardless of the number of sales, so his weekly pay is $p_C(s)=900$ .

Answer: {MMM ,MCC ,CMC, CCM ,CMM ,MCM ,MMC ,CCC }

Step-by-step explanation:

The sample space of an random experiment is the set of all possible results of that particular experiment.

Let C denotes the event when dog catches the throw and M denotes the event when dog misses the throw.

Given: Caleb throws a ball three times for his dog leo.

Then the sample space for the situation is given by :-

{MMM ,MCC ,CMC, CCM ,CMM ,MCM ,MMC ,CCC }

Solve each linear system by Elimination. 2x + 3y =2, 4x-2y=4

KonstantinChe [14]

Answer:

Step-by-step explanation:

First, we will eliminate the x, so we multiply the first one by 2.

4x+6y=4

4x-2y=4

So, we have y=0, and we put that in the equations, so x is 1

Please include work!

aleksandrvk [35]

Answer:

A) y = x^2 -1

B) -y = 2x^2 +1 We multiply B) by -1

B) y = -2x^2 -1

We can then say x^2 -1 = -2x^2 -1

3 x^2 = 0

x = 0

************* Double-Check: ******************

Equation A) y = -1 and

Equation B) y = -1

The base of a triangular prism is an isosceles right triangle with a hypotenuse of 72−−√ centimeters. The height of the prism is

Amiraneli [1.4K]

Answer:

Step-by-step explanation:

Surface area = lateral area + 2(area of base)

Lateral area = perimeter of base * height.

Because it is a isosceles right triangle, both sides are equal.

$x^{2} +x^{2}$ = 72

2 $x^{2}$ = 72. Divide both sides by 2

$x^{2}$ = 36. Square both sides.

x = 6.

So the perimeter of the base = 6 + 6 + $\sqrt{72}$ = 20.485281374239

Lateral area = 20.485281374239 * 7 = 143.397 $cm^{2}$

Area of base is (1/2)base * height.

(1/2)(6)(6) = 18

Using the surface area formula

surface area = 143.397 + 2(18) = 179.4 $cm^{3}$
