Answer:

y =x+3

Step-by-step explanation:

We need to find the slope

Find 2 points

(-3,0) and (0,3)

Slope = (y2-y1)/(x2-x1)

= (3-0)/ (0--3)

= (3-0)/ (0+3)

=3/3

We know the y intercept ( where it crosses the y axis) is at 3

We can write the equation in the form y= mx+b

y = 1x+3

y =x+3

area=(b1+b2)*h all divided by 2

a=(12+12+8.7)*4.9 all divided by 2

a=32.7*4.9/2

a=160.23/2

a=80.12 sq. ft.

The Jonas school district gives awards to its schools based on overall student attendance. The data for attendance are shown in

Evgesh-ka [11]

The most consistent attendance is the one that has less variability (it's more regular). Not necessarily the one with more students. So, the case with less variability is the one with less IQ, sigma or range (all three measure the dispersion of a distribution. IQ is more robust than sigma, and sigma more than the range, although in practice everyone uses sigma).

So, the answer to A) is the third High School: HS P

B) Here one looks at the central measurement: mean, median. This example is not super easy. HS N has the highest mean value, but HS P has the highest median. The median is more robust than the mean, since it is less affected by outliers. So HS P is a good candidate.

Finally, looking at the Low/High values, one can see that the high is the same: some day(s) when all students went and all HS have a maximum number of 180 students. However, the highest low is HS P.

So, I think HS P should also be awarded for the highest rate, since its median
is the highest and the lower number of students is the highest.

Median means 50% of the cases have values less than the median. Mean is an average.

NEED HELP NOW! A can of paint holds 500 mL of paint and is 6 in. tall. What is the diameter of the can? (Hint: 500

Setler [38]

Answer: 2.5 in

Step-by-step explanation:

A paint can is assumed to be a cylindrical shape. The formula for volume of a cylinder is V = Pi * r^2 * h

The volume is 500 mL, which we are told is 30.512 cubic inches

The problem says we can approximate Pi to be 3.14

The height is 6 in

So we need to solve for diameter of the base. In order to do that, solve for the radius first, and since d = 2r, just double the value of the radius

After plugging in what we know to the formula, we get
30.512 in^3 = 3.14 * r^2 * 6 in

30.512 in^3 / (3.14 * 6 in) = r^2

1.619533 in^2(rounded) = r^2

(1.619533 in^2)^(1/2) = l r l

1.272609 in (rounded) = r

Note: on the above step, we can immediately reject the negative solution, because a radius cannot be negative

Now that we have the radius, we simply double it to find the diameter

d = 2r

d = 2 * 1.272609

d = 2.545218

Since the question asked for the diameter rounded to the nearest tenth, the final answer is diameter = 2.5 in

Which expression is a possible leading term for the polynomial function graphed below?

Anon25 [30]

Answer:

D, 22x^9

Step-by-step explanation:

Here's a key for end behavior: Look at the leading term

x^even = x -> neg inf, f(x) -> pos inf; x -> pos inf, f(x) -> pos inf

-x^even = x -> neg inf, f(x) -> neg inf; x -> pos inf, f(x) -> neg inf

x^odd = x -> neg inf, f(x) -> neg inf; x -> pos inf, f(x) -> pos inf

-x^odd = x -> neg inf, f(x) -> pos inf; x -> pos inf, f(x) -> neg inf

Please answer ASAP. The question is down below. thanks.

Answer:

(-2,-4)

Step-by-step explanation:

The vertex of a parabola is it's lowest (or highest, but lowest in this context) point. Your lowest point is (-2,-4), so that is your answer.
