Step-by-step explanation:
<u>QUESTION 1</u>
The given data set for the expenditure is
The formula for calculating the mean is given by,
We need to add all the expenditure and divide by the total number of days.
This gives us,
to the nearest hundredth.
<u>QUESTION 2</u>
The standard deviation of the data set is given by the formula;
This implies that,
This will give us,
to the nearest hundredth,
.
<u>QUESTION 3</u>
The variance is the square of the standard deviation.
To the nearest hundred gives,
10 sin A + 16 = 3 sin A 9
You are given a line is standard form, so to transform it to the slope-intercept form, you simply have to solve it for y, and you will have y=mx+b.
2y-3x=10 add 3x to both sides
2y=3x+10 divide both sides by 2
y=1.5x+5, since y=mx+b, m=slope and b=y-intercept
slope=1.5 and the y-intercept is, technically the point, (0, 5)
First I don’t know if it is a typo or what so im assuming
that you are just repeating the numbers. So 12 in represents 45 mile in the map
so 1 mile can be calculated by using ratio.
<span>Map distance = 1 mile ( 12 in / 45 mile) = 0.27 inch in the
map</span>
<span>my answer is not in your choices, i think, i didnt get your given. so just follow the steps and you will get the correct answer</span>
