Select the correct answer. During the summer, Jody earns $10 per hour babysitting and $15 per hour doing yardwork. This week she

worked 34 hours and earned $410. If x represents the number hours she babysat and y represents the number of hours she did yardwork, which system of equations models this situation? A. x + y = 34 10x + 15y = 410 B. x + y = 410 10x + 15y = 34 C. x + y = 34 15x + 10y = 410 D. x + y = 410 15x + 10y = 34

Answer:

  A.  x + y = 34; 10x + 15y = 410

Step-by-step explanation:

Jody's total hours will be the sum of the hours spent on each job:

  x + y = 34 . . . . . total hours

Jody's total earnings will be the sum of the earnings from each job:

  10x +15y = 410 . . . total earnings

So, the system of equations is ...

  • x + y = 34
  • 10x + 15y = 410

Heinz has a list of possible functions. Pick one of the g(x) functions below, show how to find the zeros, and then describe to H
MrRissso [65]

<span>g(x) = x3 – x2 – 4x + 4 </span>

<span>You can find the zeroes by factoring the equation. x<span>2  </span>(x - 1) - 4(x - 1) = 0 </span>

<span>(x2 - 4) (x - 1) = 0 </span>

(x + 2) (x - 2) (x - 1) = 0

x = 2, -2, and 1

The following are the key features of g(x):

g'(x) yields the slope

g''(x) yields the concavity

g'(x) = 0 provides the critical points

<span>g''(x) = 0 provides the point of inflection</span>

The manager at the local auto shop has found that the probability that a car brought into the shop requires an oil change is 0.8
Ber [7]

Answer:

0.85

Step-by-step explanation:

Given two events A and B, the probability that either A or B occurs is given by:

p(A\cup B) = p(A)+p(B)-p(A\cap B)

where

p(A) the probability that A occurs

p(B) is the probability that B occurs

p(A\cap B) is the probability that both A and B occur at the  same time

In this problem, we know the following facts:

p(o) = 0.83 is the probability that the car requires an oil change

p(b)=0.17 is the probability that the car requires a brake repair

p(o\cap b) = 0.15 is the probability that the car requires both an oil change and brake repair

Therefore, the probability that either o (car requiring oil change) or b (car requiring brake repait) occur is:

p(o\cup b)=p(o)+p(b)-p(o\cap b)=0.83+0.17-0.15 = 0.85
