Juliette [100K]

50,000
because if it was 55,000 it would be rounded up to 60,000, if it has 5 or more it's rounded up and if it has 4 or less it gets rounded down

Carl earned grades of 62, 78, 59, and 89 on four math tests.

QveST [7]

Answer:

Mean, m = 72

Step-by-step explanation:

It is given that, Carl earned grades of 62, 78, 59, and 89 on four math tests.

It is required to find the mean of his grades.

Mean of a data is given by :

$m=\dfrac{\text{sum of observations}}{\text{total no of observations}}$

Sum of observations is 62 + 78 + 59 + 89 = 288

Total no of observations are 4

So, mean of his grades is :

$m=\dfrac{288}{4}\\\\m=72$

So, the mean of his grades is 72.

Write the equation of the line that passes through the points (5,0) and (-6, -1).

jonny [76]

Answer:

The equation in point-slope form is: $\mathbf{y=\frac{1}{11}x-\frac{5}{11} }$

Step-by-step explanation:

We need to find equation of line in point slope form that passes through points (5,0) and (-6, -1).

The general equation of point slope form is: $\mathbf{y-y_1=m(x-x_1)}$

where m is the slope of line.

We need to know Slope m

Finding Slope m

Finding Slope m using formula: $Slope=\frac{y_2-y_1}{x_2-x_1}$

We have $x_1=5, y_1=0, x_2=-6 \ and \ y_2=-1$

Putting values and finding slope

$Slope=\frac{-1-0}{-6-(5)}\\Slope=\frac{-1}{-6-5}\\Slope=\frac{-1}{-11}\\Slope=\frac{1}{11}$

So , slope m is: $\mathbf{m=\frac{1}{11}}$

Using point (5,0) and slope m =1/22 the equation of point-slope form is:

$y-y_1=m(x-x_1)\\y-0=\frac{1}{11} (x-5)\\y=\frac{1}{11}x-\frac{5}{11}$

So, the equation in point-slope form is: $\mathbf{y=\frac{1}{11}x-\frac{5}{11} }$

How many miles does it travel in 1 hour?

podryga [215]

It would be 2.1 hours or about 2 hours.

It says the train travels about 2118 miles per 8 miles. So, divide 2118 by 8, which gives you 264.75 (when you see the word PER it usually indicates to divide). That gives you part A.

Then, you divide 560, (which is t<span>he distance between Columbus, Ohio, and New York) by 264.75 to see how many hours it took, which gives you 2.1152030217...., which simplifies to 2.1. Which gives you the answer for B.

So,
A is 560 and
B is 2.1 or 2
