c. 32

Step-by-step explanation:

Answer:

Step-by-step explanation:

the survey represents quantative data

The statement which is true about the frequency is About one-fourth of the cable-television customers are not satisfied.

The correct option is (D).

Frequency refers to the number of times an event or a value occurs. A frequency table is a table that lists items and shows the number of times the items occur.

The first statement doesn't satisfy.

The second statement is wrong because the greatest customers of cable television are not satisfied.

The third statement is also wrong because the customers surveyed for the cable television is less than half the total customers surveyed

The fourth statement is correct because,

=[tex]\frac{1}{4}[/tex] * 1109

= 277.25 which is very close to 285.

Hence, About one-fourth of the cable-television customers are not satisfied.

Answer:

Step-by-step explanation:

0 times anything is zero

ANSWER

x=-1.2 or x=1.6

EXPLANATION

The given equation is:

[tex] 5{x}^{2} - 2x - 10 = 0[/tex] Group and combine the constant terms:

[tex]5{x}^{2} - 2x = 10 [/tex]

Divide through by 5

[tex]{x}^{2} - \frac{2}{5} x = 2[/tex]

Add the square of the coefficient of x to both sides:

[tex]{x}^{2} - \frac{2}{5} x + \frac{1}{25} = 2 + \frac{1}{25} [/tex]

The left hand side is now a perfect square

[tex]( {x - \frac{1}{5} })^{2} = \frac{51}{25} [/tex]

Take square root:

[tex]{x - \frac{1}{5} }=\pm \sqrt{\frac{51}{25}} [/tex]

[tex]{x = \frac{1}{5} }\pm \frac{ \sqrt{51} }{5}[/tex]

Answer:

1)he maximum height your feet will be above the ground is 12

2)Will you be able to dunk the ball= yes

Step-by-step explanation:

Given:

In order to dunk the basket ball, height needed to jump= 2.5 feet

The height that your feet need to be of the ground is given by the function h(t)= -16t^2+12

1) the maximum height your feet will be above the ground=?

Given function of height,h(x)=-16t^2+12

finding maximum of the above function

The maximum of any function written in form of ax^2+bx+c is given by

max= c - (b2 / 4a)

Putting values c=12, b=0 and a=16, we get

max= 12-(0^2/4(-16))

      = 12 -0

      =12 feet

he maximum height your feet will be above the ground is 12 feet.

2)  Will you be able to dunk the ball=?

As the maximum height the feet will be above the ground is 12 feet which is greater than the height needed to jump in the air to dunk the ball 2.5 feet  i.e.

12>2.25

hence yes you will not be able to dunk the ball !

The square root of 39 is ~6.25 so 6 is closest

Answer:

2

Step-by-step explanation:

Think:  2.39 is sandwiched between the perfect squares 1 and 4.

The difference between 1 and 4 is 3.  From 1 to 2.39 is a step of 1.39; from 2.39 to 4 is a step of 1.61.  Therefore, 2.39 is closer to 1 than to 4, and we estimate 2.39 to be 2 (to the nearest integer).

Answer:

Paul purchased 23 pieces of pepperoni pizza

Step-by-step explanation:

Let pepperoni pizza pieces = x

and plain pizza pieces  = y

So, the equations will be:

AS pepperoni pizza piece is sold for $1.15 and plain pizza is sold for $0.90 and Paul paid $39.05

1.15 x + 0.90 y = 39.05    eq(1)

Paul bought total 37 pieces of pizza so,

x + y = 37      eq(2)

Solving eq(1) and (2)  we can find the pieces of pepperoni pizza bought by Paul.

Multiplying equation (2) with 1.15 and subtracting eq(1) and eq(2)

1.15 x + 0.90 y = 39.05

1.15 x + 1.15 y = 42.55

-         -              -

__________________

0 x - 0.25 y = -3.5

y = -3.5/-0.25

y = 14

Putting value of y in equation(2)

x+y = 37

x + 14 = 37

x = 37 - 14

x = 23

So, Paul purchased 23 pieces of pepperoni pizza as x represents pepperoni pizza pieces.

By setting up and solving a system of linear equations, we determined that Paul purchased 23 pieces of pepperoni pizza for Pam's party.

To determine how many pieces of pepperoni pizza Paul purchased for Pam's party from Perry's pizza parlor, we can set up a system of equations based on the cost of each piece and the total amount spent. Let x represent the number of pepperoni pizzas at $1.15 each and y represent the number of plain pizzas at $0.90 each. We have the following equations based on the given information:

x + y = 37 (total pieces of pizza purchased)

1.15x + 0.90y = $39.05 (total amount spent)

By solving these equations simultaneously, we can find the exact number of pepperoni and plain pizzas that Paul purchased. Multiplying the second equation by 100 to clear the decimals, we get:

115x + 90y = 3905

Now, multiply the first equation by 90:

90x + 90y = 3330

Subtract the modified first equation from the modified second equation:

(115x + 90y) - (90x + 90y) = 3905 - 3330

25x = 575

x = 23

Paul purchased 23 pieces of pepperoni pizza.

[tex]y=\frac{1}{36}x^2[/tex]

Step-by-step explanation:

The focus of the parabola is (0,9)

and the directrix is y=-9.

The equation of this parabola is given by:

[tex]x^2=4py[/tex]

The vertex of this parabola is at the origin.

The value of p is the distance from the vertex to the focus.

p=9-0=9

The equation of the parabola is

Answer:

[tex]x=4+-2\sqrt{7}[/tex]

Step-by-step explanation:

To solve, we need to take square root of both sides first:

[tex](x-4)^2=28\\\sqrt{(x-4)^2} =+-\sqrt{28} \\x-4=+-\sqrt{28}[/tex]

Now we use the property of radical shown below to simplify square root of 28:

Property:  [tex]\sqrt{x*y}=\sqrt{x} \sqrt{y}[/tex]

Now, we have:

[tex]x-4=+-\sqrt{28}\\x-4=+-\sqrt{4*7}\\x-4=+-\sqrt{4}\sqrt{7}\\x-4=+-2\sqrt{7}[/tex]

Now we take 4 to the other side and isolate x:

[tex]x-4=+-2\sqrt{7} \\x=4+-2\sqrt{7}[/tex]

first answer choice is right.

The answer is:

The correct answer is the first option.

[tex](x-4)^{2}=4+-2\sqrt{7}[/tex]

To solve the problem, we must remember the following square root property:

[tex]\sqrt{ab}=\sqrt{a}\sqrt{b}[/tex]

So,

We are given the expression:

[tex](x-4)^{2}=28[/tex]

Now, isolating we have:

First, applying square root to both sides of the equation in order to simplify the quadratic term, we have:

[tex]\sqrt{(x-4)^{2} }=\sqrt{28}\\(x-4)=\sqrt{4*7}\\\\x=4+-(\sqrt{4}*\sqrt{7})\\\\x=4+-2\sqrt{7}[/tex]

Hence, the correct answer is the first option.

[tex](x-4)^{2}=4+-2\sqrt{7}[/tex]

Answer:

84 and 36

Step-by-step explanation:

The ratio of two numbers is 7:3.

We don't know what the numbers are, but since their ratio is 7:3, we can let the numbers be 7x and 3x. Notice that the ratio between 7x and 3x is 7x/3x = 7/3, so we still have the same ratio, 7:3.

The difference between the numbers is 48.

7x - 3x = 48

4x = 48

x = 12

7x = 7(12) = 84

3x = 3(12) = 36

The numbers are 84 and 36.

Check:

7/3 = 2.333...

84/36 = 2.333...

84 and 36 are int he same 7:3 ratio as 7:3.

84 - 36 = 48

The difference between 84 and 36 is 48 like the problem states.

This shows our answer, 84 and 36, is correct.

Hi, hope you’re having a good day today!!!

Answer:

84:36

(The explanation is really really long, so you may want to skip it, unless this is a test or you want a better understanding then, yeah)

So first, you have 7:3

Then, you have to multiply both by the same number to get an equal ratio to 7:3,

Let’s try 7*10=70 and 3*10=30 70-30=40, so you know that the answer is close,

Then, let’s try 7*11=77 and 3*11=33, subtract and you get 44. Nope, not the answer

So, finally let’s try 7*12=84 and 3*12=36, and 84-36=48!!!!

So, the answer is explained! Wait, but you still have to put them like ratios (if this chapter is ratios and proportions)

84:36 or 84 to 36, either way.

Answer:

|x| + |y| = 29

Step-by-step explanation:

We have been given the expression;

|x| + |y|

We are required to evaluate the above expression if;

x = 16 and y = 13

The parallel vertical lines imply that we are dealing with the absolute value of x and y;

|x| + |y| = |16| + |13|

           = 16 + 13

           = 29

Answer:

The correct answer is 29

Step-by-step explanation:

Points to remember

|x| = x

|-x| = x

It is given an expression, |x| + |y|

To find the value of given expression

|x| + |y|  if x = 16 and y = 13

Substitute the value of x and y in the above expression,

|x| + |y| = |16| + |13|

 = 16 + 13 = 29

Therefore the correct answer is 29

Answer:

(x - 3)(x + 1)(x + 5)

Step-by-step explanation:

I'd use synthetic division instead.  If we were to find the roots of the given polynomial, we could from them write the factors as well.

The divisor x + 5 corresponds to root x = -5.  Setting up synthetic div.,

-5   )   1    3    -13    -15

               -5     10    +15

      -----------------------------

           1   -2     -3      0

Since the remainder is 0, we know that -5 is a root and (x + 5) is a factor.  Moreover, we know that the coefficients of the quotient are 1, -2 and -3.

1x² - 2x - 3 can be factored:  the factors are (x - 3) and (x + 1).

So the end result for this problem is (x - 3)(x + 1)(x + 5).
