Answer: 443.2

Step-by-step explanation:

The mean of a data set is given by :_

$\text{Mean}=\frac{\text{Sum of all data values}}{\text{Number of data values}}$

The given data :

412, 428, 475, 462, 481, 407, 420, 467, 472, 408

The mean of the given data set is will be :_

$\text{Mean}=\frac{412+428+475+462+481+407+420+467+472+408}{10}\\\\\Rightarrow\text{Mean}=\frac{4432}{10}\\\\\Rightarrow\text{Mean}=443.2$

Add up all the numbers than divide by how many number they are so when you add them all you get 4432, divide it by 10.

For others, your answer is 443.2.

Answer:

y varies of directly as x. This means that the equation is of the form y=kx where k is any number.

Substituting y=12 when x=4, we get

12=k×4⇒k=3

Hence, the required equation is y=3x.

The value of y when x=5 is y=3x5=15.

WILL GIVE BRAINLIEST find the value of r (-4,8), (r,12), m=4/3 (show your work pls)

OLEGan [10]

Answer:

r = 13

Step-by-step explanation:

The first step is to find b from y=mx=b using m=4/3 and (-4,8)

$8=\frac{4}{3}(-4)+b$

After solving the equation, b will equal -16/3 making the final equation be

$y=\frac{4}{3} x-\frac{16}{3}$

Using the equation, you can solve for r.

$12=\frac{4}{3} x-\frac{16}{3}$

This will bring the answer being r = 13

if your car gets 26 miles per gallon how much does it cost to drive 420 miles when gas is $2.80 per gallon

Kitty [74]

Answer:

$45.22

Step-by-step explanation:

The number of miles per gallon can be represented by the ratio:

$\frac{miles}{gallon}=\frac{26}{1}$

Since we know the unit rate of 26 miles per gallon of gas, we can set up a proportion, or equivalent ratios, to find the number of gallons needed for 420 miles:

$\frac{26}{1}=\frac{420}{x}$ , where 'x' is the number of gallons of gas

cross-multiply and divide: 26x = 420 or x ≈ 16.15 gallons

If gas is $2.80 per gallon, take the total number of gallons needed and multiply by $2.80:

16.15 x $2.80 = $45.22
