Answer:

Well, you find the mean by adding up all the totals then dividing by how many sets of the totals you have. the mean gives you the average of the whole data set, which can be helpful to know when you are maybe trying to raise awareness for something and you want to know the average, I don't know, animals killed in the forest fire, sadly.

Answer:

y = 4x + 3

Step-by-step explanation:

as the line is parallel to the given equation, the gradient (4x) must stay the same, and as it must pass through the point (-2, -5), we can solve for the y intercept:

to calculate for the y intercept, it is best to express the equation in slope intercept form:

y = mx + b

in this equation, mx stands for the gradient, which ive already highlighted remains 4x, and b stands for the y intercept (which we don't know yet).

y = 4x + b

what we have been given instead is the coordinates for the point this line crosses through (-2,-5) meaning when x = -2, y = -5.

Using this information, we can replace x and y in the equation:

-5 = 4(-2) + b

with consideration to the order of operations, it is important to solve the brackets first

-5 = -8 + b

now to get b by itself add 8 to both sides of the equation:

-5 + 8 = -8 + 8 + b

3 = b

now we remember from the slope intercept equation, b = the y intercept, so we can now solve the equation.

y = 4x + b

replace b with the number we solved for (3).

y = 4x + 3

this is the equation of the line that is parallel to y = 4x + 1, and passes through the point (-2, -5)

hope this helps :)

Dan is 8 years older than Fiona. Gavyn is 9 years younger than Fiona. If the total of their ages is 56, how old is the eldest of

r-ruslan [8.4K]

Answer:

Step-by-step explanation:

If Fiona's age is x, Dan and Gavyn's ages respectively are x + 8 and x - 9. We can write:

x + x + 8 + x - 9 = 56

3x - 1 = 56

3x = 57

x = 19

The eldest is Dan (because x + 8 > x and x + 8 > x - 9). His age is x + 8 = 19 + 8 = 27.

Solve y = x - 5 if the domain is -3

DedPeter [7]

Answer:

y = -8

Step-by-step explanation:

The domain is the x values so x=-3

y = x-5

Substituting x=-3

y = -3-5

y=-8

Abel was wrapping a gift for an upcoming party. He began with 20 1/2 feet of paper. He used 5 5/12 feet on his first gift and 3

FrozenT [24]

Hey there!

$20 \dfrac{1}{2} - 5 \dfrac{5}{12} - 3 \dfrac{1}{3} + 2 \times 10 \dfrac{1}{2} \\ = \dfrac{41}{2} - \dfrac{65}{12} - \dfrac{10}{3} + 21 \\ = \dfrac{246}{12} - \dfrac{65}{12} - \dfrac{40}{12} + 21 \\ = \dfrac{141}{12} + 21 \\ = 32 \dfrac{3}{4}$

Answer : 32 3/4 feet or in decimal form, 32.75 feet.

Hope this helps. - M
