1 answer:

7 0

Will lets say box one is red (r), box two is green(g), Box three is blue(b) and box four is yellow(y). If you have 10 tennis balls then 2 tennis balls in the Red Box, 2 tennis balls in the green box, 2 tennis balls in the blue box and 2 tennis balls in the yellow box now you should have two left over so but one in the Red box and the other in the Blue box! I don't know if this is right but I am a little confused on what your saying so Hope this helps:)

What is the equation of the line that passes through the point (-5, -3) and has a slope of -1

lesya [120]

Answer:

y= -x-8

Step-by-step explanation:

The ones in the equation are in subscript, couldn't get the equation creator to work properly....DO NOT multiply by one, they are merely subscript meant to help you identify which pair to use.

y-y1=m(x-x1)

-5=x1

-3=y1

-1=m

y- -3=-1(x- -5) then you arrive at y+3=-1(x+5)

y+3=-x-5 now you isolate the y on the left y=-x-8

klasskru [66]

Answer:

168 hours

8,736 hours

Step-by-step explanation:

Determine how many hours are equal to 1 week.

1 week = 7 days

1 day = 24 hours

1 week * (7 days)/(1 week) * (24 hours)/(1 day) = 168 hours

How many hours are in a year (52 weeks)?

1 week = 168 hours

1 year * (52 weeks)/(1 year) * (168 hours)/(1 week) = 8,736 hours

One year Thomas had the lowest ERA (earned-run average, mean number of runs yielded per nine inning pitched) of any male pitcher

valkas [14]

Answer:

Thomas had an ERA with a z-score of -2.82.

Karla had an ERA with a z-score of -2.81.

Thomas had the better year compared with his peers, since his ERA had the lower Zscore.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by

$Z = \frac{X - \mu}{\sigma}$

The ERA is the Earned Runs Average per 9 innings. This mean that the lower the ERA is, the better it is. So, between Thomas and Karla, whoever has the lower Zscore had the better season.

Thomas

For the males, the mean ERA was 4.837 and the standard deviation was 0.541. This means that $\mu = 4.837, \sigma = 0.541$ .
