Answer: 1600batteries

Step-by-step explanation:

Let the number of inspected battery be y

2.5% of y = 40

5/2% of y = 40

Change 5/2% to fraction

5/200 × y = 40

5y/200=40

Cross multiply

5y= 40×200

5y=8000

y=8000÷5

y=1600

The total number of battery inspected is 1600.

calculate the distance between the two points shown on the graph below give your answer correct to 2 decimal places if necessary
GenaCL600 [577]

Answer:

Find the distance between (-1, 1) and (3, 4).

This problem is solved simply by plugging our x- and y-values into the distance formula:

D=(3−(−1))2+(4−1)2−−−−−−−−−−−−−−−−−−√=

=16+9−−−−−√=25−−√=5

Sometimes you need to find the point that is exactly between two other points. This middle point is called the "midpoint". By definition, a midpoint of a line segment is the point on that line segment that divides the segment in two congruent segments.

If the end points of a line segment is (x1, y1) and (x2, y2) then the midpoint of the line segment has the coordinates:

(x1+x22,y1+y22)

The average height of a 13 year old male in the U.S. is 60 inches, with a standard deviation of 2 inches. The average weight of
Romashka [77]

Since the average height is 60 inches and its deviation is 2 inches, one deviation to the right (or higher) is 62 inches (60 + 2). Two deviations is 64 inches, three deviations is 66 inches, and four deviations is 68 inches.


Since the average weight is 100 pounds and its deviation is 5 inches, we repeat the process from finding heights to get to 115 pounds. That takes three deviations.


The MORE deviations away, the more unusual it is. So the height (4 deviations) is more unusual than the weight (3 deviations).
