Compare centers mean you need to compare the median of the two box plots.

Box 1: Median (Q2) = 40

Box 2: Median (Q2 is between 40 and 50 (40 < Q2 < 50)

So the center of box 2 is greater than center of box 1

Hope it helps.

Which quadratic function has Vertex (-1,4) and passes through (4,19) <br> HELP

hichkok12 [17]

Answer:

$f(x)=\frac{3}{5}(x+1)^2+4$

Step-by-step explanation:

The equation of a quadratic function in vertex form is given by:

$f(x)=a(x-h)^2+k$

Where (h,k) is the vertex.

It was given in the question that the vertex of the parabola is (-1,4).

When we substitute the vertex into the formula we get:

$f(x)=a(x+1)^2+4$

The parabola also passes through (4,19) hence it must satisfy its equation.

$19=a(4+1)^2+4$

$19-4=a(5)^2$

$15=25a$

We divide both sides by 25 to get:

$a=\frac{15}{25}= \frac{3}{5}$

Hence the quadratic function is:

$f(x)=\frac{3}{5}(x+1)^2+4$

The table shows the total cost for different numbers of jackets. Number of jackets 2 5 7 Total cost ($) 46. 50 116. 25 162. 75 W

Bond [772]

The cost price of 1 jacket is $23.25 and the cost price of 3 jackets is $69.75.

<h3>What is the cost price?</h3>

Cost price is the total amount of money to produce a given product or provide a given service.

Given cost prices for jackets are,

Jackets Cost Price

2 46.5

5 116. 25

7 162. 75

We need to calculate the cost price of 3 jackets. First, we need to find out the cost price of one jacket.

$2 \; \rm Jackets =\$ 46.50$

$1 \;\rm Jacket = \dfrac {\$46.50}{2}$

$1 \;\rm Jacket = \$ 23.25$

Now the cost price of 3 jackets is given as,

$3\;\rm Jackets = \$23.25 \times 3$

$3\;\rm Jackets = \$69.75$

Hence we can conclude that the cost price of 3 jackets is $69.75.

Find the area of a triangle with a base of 7.5 m and a height of 4*

oksian1 [2.3K]

Answer:

15 units²

Step-by-step explanation:

Hi there!

$A=\displaystyle\frac{1}{2} bh$ where <em>b</em> is the base and <em>h</em> is the height

Plug in the base (7.5) and height (4):

$A=\displaystyle\frac{1}{2} (7.5)(4)\\\\A=\displaystyle\frac{1}{2} (30)\\\\A=15$

Therefore, the area of the triangle is 15 units².

I hope this helps!
