Step-by-step explanation:

To receive an award, student must obtain a score at or above the upper quartile, from.tye boxplot, the upper quartile is depicted by the endpoint of the box. Hence, the upper quartile of the distribution is 74. Hence only stude Ts who score 74 and above will receive an award Hence, the minimum score required is 74.

The equation of a parabola is y=x^2–4x+13. Write the equation in vertex form.

Simplify any fractions.

Answers

Answer:

y = (x - 2)² + 9

Step-by-step explanation:

To obtain the equation in vertex form use the method of completing the square.

Add/ subtract ( half the coefficient of the x- term)² to x² - 4x

y = x² + 2(- 2)x + 4 - 4 + 13

  = (x - 2)² + 9 ← in vertex form

Answer:

vertex form : y=(x-2)^2+9

Step-by-step explanation:

To convert a parabola from standard form y=x^2-4x+13 to vertex form, we complete the square.

first, complete the square using the x-terms, use the constant term to adjust and make a perfect square.

y=  x^2-4x+4   +  9

Factor the first three terms on the right-hand side.

y=(x-2)^2 + 9

the resulting express is then the vertex form, which means that

the vertex is at (x-2) = 0, x=2, and at y=9.  

What value of x makes the 2 triangles congruent by HL? Find the length of CB

Answers

Step-by-step explanation:

here's your solution

==> Both traingle are congruent

==> BC = BD. [ c.p.c.t ]

==> x + 8 = 3x - 14

==> x - 3x = - 14 - 8

==> - 2x = - 22

==> x = 22/2

==> x = 11

now CB = x + 8 = 11 + 8

CB = 19

A school purchases boxes of candy bars. Each box contains 50 candy bars. Each box costs $30. How much does the school have to charge for each candy bar to make a profit of $10 per box?
A $0.40
B $0.50
С $0.80
D $1.25​

Answers

Answer:

C

Step-by-step explanation:

30/50 = each bar costs 0.60 dollars

10/50 = 0.20 dollars

0.60 + 0.20 = 0.80

C. Because If each individual box is $30 and there is 50 in each, divide 30/50. Then you know how much they are profiting off that amount. Then calculate for $10 per box

The circumference of a circle is 9π m. What is the area, in square meters? Express your answer in terms of π

Answers

Answer:

[tex]20.25\pi\:\mathrm{m^2}[/tex]

Step-by-step explanation:

Formulas to know:

Area of a circle: [tex]A=r^2\pi[/tex]Circumference of a circle: [tex]C=2r\pi[/tex]

Since we know the circumference, we can use formula for the circumference of a circle to find the circle's radius:

[tex]9\pi=2r\pi,\\9=2r,\\r=4.5[/tex]

Now we can plug in [tex]r=4.5[/tex] into the formula for an area of a circle:

[tex]A=4.5^2\pi=\boxed{20.25\pi\:\mathrm{m^2}}[/tex]

Answer:

20.25 pi

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi *r

9 pi = 2 * pi *r

Divide each side by 2pi

9pi / 2 pi = 2 pi r / 2 pi

4.5 = r

Now we can find area

A = pi r^2

   = pi ( 4.5)^2

     20.25 pi

Find the sum of the 1st 100 terms: 100+98+96+....

Answers

Answer:

First we Check if its an AP or GP

Its an AP because the Second term Minus the First term is = to 3rd term Minus Second term

Since it said "Sum"

The formula we should think Of is

Sn = n/2[2a + (n-1)d]

n=100

a(First term) =100

Common difference 'd' = Second term - First term or Third term - Second term

So

d= 98-100 or 96-98

d=-2.

Applying the Formula...

Sn = 100/2 [2(100) + (100-1)(2)]

Sn = 50[200 + (99)(2)]

Sn= 50[200 + 198]

Sn = 50[398]

Sn = 19,900.

Is it linear , quadratic, exponential

Answers

Answer:

Exponential

Step-by-step explanation:

So lets look at the table.

When x = 1, y = 3

When x = 2, y = 9.

Hmmm, this doenst seem like x+number=y. It doesnt seem like a quadratic, where the values go up, then down, then up again. Or vise versa.

So this rules out linear and quadratic, for the x doesnt change by a constant, or change the direction of y.

This leaves exponential or none of the above.

When x = 3, y = 27

When x = 4, y = 81

This seems like a exponent, since:

3 to the first power is 3

3 to the second power is 9

3 to the third power is 27

and 3 to the fourth power is 81

Answer:

exponential function

What is the diameter of a hemisphere with a volume of 863 in', to the nearest tenth

Answers

Answe 33.2

Step-by-step explanation:

863÷3.14=274.8407643312 find the square root then multiply by 2

The diameter of the hemisphere is twice the radius,

d = 2r ≈ 16.6 inches

What is volume?

Volume is the measure of the amount of space occupied by a three-dimensional object. It is usually expressed in cubic units, such as cubic meters, cubic feet, or cubic centimetres.

The volume of a hemisphere is given by V = (2/3)πr³, where r is the radius of the hemisphere.

We can solve for the radius as follows:

V = (2/3)πr³

863 = (2/3)πr³

r³ = (863 x  3) / (2π)

r³ ≈ 650.35

r ≈ 8.3 inches

The diameter of the hemisphere is twice the radius, so:

d = 2r ≈ 16.6 inches

Find the value of r.

Answers

Answer:

r = 10.5

Step-by-step explanation:

using the Pythagorean theorem:

(7 + r)² = 14² + r²

49 + 14r + r² = 196 + r²

subtract r² from both sides of the equation:

14r + 49 = 196

subtract 49 from both sides:

14r  = 147

divide both sides by 14:

r = 10.5
