It would be 20 hrs because if you put them both in an equation aka y=25x+100 and y=30x just plug in numbers into the x until they both have the answer which in this case is 20
The correct answer is: [A]: " <span>x - 3 " .

The midpoint would be (7, 5)
The midpoint of any two points is simply the average of the x points and the average of the y points. So we'll start by averaging the 2 x points together. To take an average, we add the two numbers together and divide by 2.
X VALUE
4 + 10 = 14
14/2 = 7
Now do the same for y
Y VALUE
22 + -12 = 10
10/2 = 5
Using those answers we can create the ordered pair (7, 5)
<span>0.053
The standard deviation of a binomial variable is
sqrt(n*P*(1-P))
where n is the sample size and P is the probability of one of the outcomes.
The sample size is 55 and we'll assume that both male and female are equally likely outcomes.
standard deviation = sqrt(55*.5*.5) = 3.7081%
44% is 1.6181 standard deviations away from the mean of 50%.
Looking this up on a standard deviation chart gives .0526 probability which we'll round to 0.053</span>
Answer:
When a product fails to perform as warranted, this is called <u>breach of warranty. </u>
