Hello, the solution is in this photo.
If the graph of the line rises from left to right, then the slope is positive.
Slope = (y2 - y1)/(x2 - x1)
---> The correct answer is 2
Answer:
75 and 85
Step-by-step explanation:
----------------------------------------------
Define Length and Width:
----------------------------------------------
Let the width be w.
Length = w + 7
----------------------------------------------
Find expression for Perimeter:
----------------------------------------------
Perimeter = 2 (Length + Width)
Perimeter = 2( w + 7 + w)
Perimeter = 2(2w + 7)
Perimeter = 4w + 14
----------------------------------------------
Answer: Perimeter = 4w + 14
----------------------------------------------
Answer: The answer is A.
Given that the formula of area of triangle is, A = (1/2)×b×h. Then substitute the following values into the formula :
b = 10 units
h = 4 units
A = (1/2)×10×40
= (1/2)×40
= 20 units²
Step-by-step explanation:
Answer:
The margin of error is multiplied by 1.41, which is 1 divided by the square root of 5.
Step-by-step explanation:
The margin of error is:
In which z is related to the confidence level, is the standard deviation of the population and n is the size of the sample.
The margin of error is inverse proportional to the square root of the sample size.
Then
Sample size n:
Modified(half the sample size):
Ratio
The margin of error is multiplied by 1.41, which is 1 divided by the square root of 5.
