I believe that the answer would be B because if you put the numbers into the variable spots, this is what you get. For example, when you put -3 into A, because it is the one with the x, and 6 in for B, you would get the first part of the equation. Then, put 12 in for C, you would get the whole equation. Sorry if this is wrong or if I did a bad job explaining this. Good luck!

Out of the 21 students in mrs Clark’s class by 3/7 of the class are boys

saul85 [17]

Answer:

There are 9 boys and 12 girls in mrs Clark's class

Step-by-step explanation:

We are given that mrs Clark has 21 students, of which 3/7 are boys

In order to find the number of boys, we multiply 21 by 3/7 which results in 9

This means there are 9 boys and then we just simply subtract 9 from 21 in order to find the number of girls 21-9=12

therefore there are 9 boys and 12 girls in mrs Clark's class

Look at this triangle work out length bc

Natali [406]

Answer:

perpendicular = 10.24 cm

Step-by-step explanation:

by pythagorus theorem,

$h {}^{2} = b {}^{2} + h {}^{2}$

( where, h = hypotenuse, b = base,

p = perpendicular )

so,

=》

$13 {}^{2} = 8 {}^{2} + p {}^{2}$

=》

$169 = 64 + p {}^{2}$

=》

$169 - 64 = p {}^{2}$

=》

$p = \sqrt{105}$

perpendicular = 10.24 ( root 105 )

30 points if correct. Select all the are true.

ivann1987 [24]

Answer:

Options B,C and E are correct choices.

Step-by-step explanation:

We are asked to find correct answers for the given box and whisker plots.

Let us our options one by one.

A. This option is false as lowest value for children's cereals is 30 and highest value for adults is 35.

B. This option is correct. We can see our upper value for combined range will be 60 and lower value will be 5 and range is upper value- lower value.

$60-5=55$

C. Since we know that we can find spread of data by its range.

$\text{Range for children's cereals}=60-30=30$

$\text{Range for adult's cereals}=60-30=30$

So option C is correct indeed.

D. This options is false because for adults mean and median are different while for children mean and median are same.

E. We can see that median for children's cereals is 45 and it is about 12 for adults.

We can see that $12*3$ . So median amount of sugar in children's cereals is 3 times as much as the median amount of sugar in adult's cereals.

Therefore, options B,C and E are correct choices.

Use point-slope form to write the equation of a line that passes through the point

solniwko [45]

Answer:

y = -5x - 25

Step-by-step explanation:

Substitute into form of y - y1 = m(x - x1): (Take the point (-7,10) for x1 & y1, m would be the slope)

y - 10 = -5(x -(-7))

y - 10 = -5(x + 7)

y - 10 = -5x - 35

y = -5x - 25

If a line has a slope of 9/5. If one of the points on the line is (-10, -16), which could be another point?

zlopas [31]

Answer:

(–5, –7)

Step-by-step explanation:

From the question given above, the following data were obtained:

Slope = 9/5

Coordinate 1 = (–10, –16)

x₁ = –10

y₁ = –16

Coordinate 2 = (x₂, y₂)

Next, we shall determine the change in x and y coordinate. This can be obtained as follow:

Slope = change in y–coordinate / change in x–coordinate

Slope = Δy / Δx

Slope = 9/5

9/5 = Δy / Δx

Thus,

Δy = 9

Δx = 5

Next, we shall determine the second coordinates as follow:

Δy = y₂ – y₁

Δx = x₂ – x₁

For x–coordinate:

x₁ = –10

Δx = 5

Δx = x₂ – x₁

5 = x₂ – (–10)

5 = x₂ + 10

Collect like terms

x₂ = 5 – 10

x₂ = – 5

For y–coordinate:

y₁ = –16

Δy = 9

Δy = y₂ – y₁

9 = y₂ – (–16)

9 = y₂ + 16

Collect like terms

y₂ = 9 – 16

y₂ = – 7

Coordinate 2 = (x₂, y₂)

Coordinate 2 = (–5, –7)
