Answer:

C.) 2(x-3)(x-4)

Step-by-step explanation:

I think so

In interval notation, square brackets indicate that a function can take on that value (or uses a less/greater than or equal to sign). Parenthesis indicate that a function cannot take on that value (or uses a less/greater than sign).

In the case of the given set, both inequality signs are less/greater than or equal to. This indicates to us that we will use brackets in both instances because the set can be equal to -2 and 2.

Step-by-step explanation:

Givens

Formula

V = pi * r^2 * h                                         Substitute givens into formula

Solution

198 cm^3 = 3.14 * 8.8 * r^2                     Combine the right

198 = 27.632 * r^2                                  Divide both sides by 27.632

198 / 27.632 = 27.632 * r^2 / 27.632

7.1656 = r^2                                            Switch the equation

r^2 =  7.1656                                           Take the square root of both sides

√r^2 =  √7.1656  

r = 2.6768

Answer:

B:11 and 1/4

Step-by-step explanation:

to divide 15 by 1 1/3 i used the Keep, Change, Flip method aka-KCF

i kept 15 over 1 changed the division sign into a multiplication sign and flipped 1 1/3 which is 4/3 to its reciprocal 3/4.

which got me the answer 45/4 i simplified it into 11 and 1/4

[tex]\frac{3}{y^{2} }[/tex]

Step-by-step explanation:

This question is asking you to simplify using the law of indices:

Just to write out the question in fraction form:

[tex]\frac{12y^{7} }{4y^{9} }[/tex]

Cancel out the 4:

[tex]\frac{3y^{7} }{y^{9} }[/tex]

Cancel out y^7:

[tex]\frac{3}{y^{2} }[/tex]

Hope this helped and brainliest please

Answer:

3/y^2

Step-by-step explanation:

1. Rewrite the division as a fraction.

= 12y^7/4y^9

2. Cancel the common factor of 12 and 4

= 4(3y^7)/4y^9

= 3y^7/y^9

3. Cancel the common factor of y^7 and y^9

= y^7 ⋅ 3/y^9

= 3/y^2

Step-by-step explanation:

The area of the poster will be 0.68 m². The number of unit squares that cover the surface of a closed-form is the figure's area.

The space filled by a flat form or the surface of an item is known as the area. Square centimeters and other similar units are used to measure area.

Given data;

Height of mom in the photo = 3 inches

Real size of photo=66 inches

Area of the photo = 15 square inches

Where x is the area of the poster, the following proportions might be used to predict how much paper Jermaine will pay for:

Area = width × length

[tex]\frac{Real \ size }{Photo \ size} =\frac{Real \ area}{Photo \ area } \\\\ \frac{66}{3} =\frac{15}{x} \\\ x=0.68 \ m^2[/tex]

Hence,the area of the poster will be 0.68 m².

The expression that represents the volume of the empty space is 9³ - 4/3π(4.5)³

The cube box has a side length of 9.

So, the volume of the box is:

V = 9³

The sphere has a radius of 4.5.

So, the volume of the sphere is:

v = 4/3π(4.5)³

Calculate the difference between both volumes:

d = 9³ - 4/3π(4.5)³

Hence, the expression that represents the volume of the empty space is 9³ - 4/3π(4.5)³

Answer:

below

Step-by-step explanation:

• We know that the initial height of Candle A is 201 millimeters and of Candle B is 290 millimeters which means the first statement is not true.

• To find the rate at which the Candle A is decreasing, we simply have to divide 201 - 177 with 4.

24 / 4 = 6

       As we can see Candle A is decreasing at a faster rate of 6 than the rate of decreasing of Candle B which is 5. This means that second statement is true.

• To find out after how many hours will the Candle B burn out we simply have to divide the initial value with the rate of change which is 5.

290 / 5 = 58

       Candle B will burn out after 58 hours. This statement is true.

• We simply have to multiply the rate of change with 10 and after that subtract the value that we get from the initial value of Candle A.

10 x 6 = 60

201 - 60 = 141

After 10 hours the height of Candle a will be 141 millimeters. This statement is true.

• We know that Candle A is burning out at a faster rate and that the Candle B was higher at start which means that

       Candle A will burn out before Candle B. This statement is true.

A null hypothesis is a statement, in which there is no relationship between two variables. An alternative hypothesis is statement in which there is some statistical significance between two measured phenomenon.

Group 1 n₁ = 50 , x₁ = 12

Group 2 n₂ = 50 , x₂ = 18

p₁ = x₁/n₁ = 12/50 = 0.24

p₂= x₂/n₂ = 18/50 = 0.36

Testing the null and alternative hypothesis

H₀ = p₁ -  p₂= 0

Hₓ =  p₁ -  p₂ < 0

Level of Significance α =0.05

Test Statistic

[tex]\rm z = \dfrac{p_1-p_2}{\sqrt{\dfrac{p_1(1-p_1)}{n_2} +\dfrac{p_2(1-p_2)}{n_2}}}[/tex]

On substituting the values

z = -0.12/0.9086

z = -1.32

p value = p(z > -1.32)

p value = 0.0934

Therefore p value > 0.05
