What is the mean of the data set?

2 answers:

4 0

You find the mean by adding each value then dividing the sum by the number of values there were so in this case you'd say 301 + 222 + 287 + 310 + 346 which is 1466 then divide by 5 because there are 5 values and your answer is 293.2!

I hope this helps

You Add All The Numbers Together

301+222+287+310+346= 1,466

Then You Divided It By How Many Sets Of Number You Have Which Would Be 5

Finally Your Answer Is 293.2

Formula: V=1/2x length x width x height= Area x height

Step 1: You find the 12 x 5 x 4.33= 259.8cm

Step 2: 259.8cm/2=129.9cm

Step 3: 129.9 x 12=1558.8cm^3

Write the slope-intercept form of the equation of the line through the given point with the given slope.

Marta_Voda [28]

-------------------------------------------------------------------------------------------------------------

Answer: $\textsf{y = x + 2}$

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{Slope = 1, Goes through (-1, 1)}$

Find: $\textsf{Determine the slope-intercept form of the equation}$

Solution: In order to determine the equation we need to first use the point-slope form which uses a slope and a point which can then be simplified and solve for y to get the slope-intercept form.

Plug in the values

$\textsf{y - y}_2\textsf{ = m(x - x}_1\textsf{)}$

$\textsf{y - 1 = 1(x - (-1))}$

Simplify and solve for y

$\textsf{y - 1 = 1(x + 1)}$

$\textsf{y - 1 + 1 = x + 1 + 1}$

$\textsf{y = x + 2}$

Therefore, the simplified equation in slope-intercept form would be y = x + 2

A tree casts a 25 foot shadow. At the same time of day, a 6 foot man standing near the tree casts a 9 foot shadow. What is the a

AysviL [449]

So, the man is 6 feet, but casts a 9 foot shadow. So, you divide 25 by 9, and then you would find it goes into it 2.8 times, so round and get 3 if you want,or keep it. And then 12, or round to 13.

Rewrite the following without an exponent (-7)⁻²

chubhunter [2.5K]

Answer:

The correct answer is 1/49

Step-by-step explanation:

In order to find this, we first can eliminate the negative in the exponent by putting the whole this in the denominator.

(-7)^-2 = 1/(-7)^2

Now we can evaluate the denominator

1/(-7)^2 = 1/49
