Answer:
Step-by-step explanation:
<h3>Part A</h3>
- a = 100 will convert the number on the numerator to whole number
- b = 10 will convert the number on the denominator to whole number
But we need a = b in order not to change the value of the fraction, therefore we choose
<h3>Part B</h3>
Multiplying both numerator and denominator by 100 will make the fraction:
- 35.86*100/2.2*100 =
- 3586/220 =
- 16 66/220 =
- 16 3/10
- 16.3
Answer:
Assumption A is violated
Step-by-step explanation:
x = number of blemishes = 8
n = sample size = 150
proportion = x/n = 8/150 = 0.0533
1. large counts: np> 10
= 150 * 0.0533 >10
= 7.995 > 10
this assumpton is obviously violated. <em><u>7.995 is not greater than 10</u></em>
<em><u></u></em>
2. Large Counts: n(1 - p) > 10
150(1-0.0533)>10
150-7.995 > 10
142.005> 10
there is no violation. The assumption is satisfied
3. This assumption is satisfied. this is because the tomatoes were selected using simple random sampling.
4. 10% of the population = 0.1 * 2000 = 200
the sample size = 150
150 < 200
this assumption is satisfied

Answer:
-x + y = 0 or x - y = 0
Step-by-step explanation:
The line passes through points (0, 0) and (4,4), then its slope is:
m = (4 - 0)/(4 - 0) = 1
Given that the line passes through (0, 0), its y-intercept is
b = 0
Using slope and y-intercept form:
y = mx + b
y = x
The standard form of a line is:
Ax + By = C
So, we have to put all variables on the left side, as follows:
-x + y = 0
Multiplying by (-1) at both sides:
x - y = 0
Answer:
Step-by-step explanation:
You have to set each runner's plan equal to each other because they are equal in the end. You start with 7 miles for Angelo and 4 miles for Marc.
x is a variable that is multiplied by the number of weeks it takes for both runners' distances to be equal. So multiply x by the miles increased every week.
Marc = Angelo
2x + 4 = x + 7
x = 3
In 3 weeks each runner will run 10 miles for the week.
