Answer:

X=4

Step-by-step explanation:

5x-4=16

    +4  +4        Add 4 on both sides

5x=20            Divide both sides by 5

x=  4

Answer:

(8,0)

Step-by-step explanation:

the three points are col linear means they are on same line

R ___________________________P_________________Q

(-12,0)                                                   (0,0)                                  (x,y)

y is zero since P is at the origin with coordinate(0,0)

PR=12 ( the distance is the absolute value and always positive)

PQ/PR=2/3

PQ/12=2/3

PQ=24/3=8

(8,0)

Answer:

x= -11

Step-by-step explanation:

distribute the 3 and the 2:   3 - 9x = -8x + 14

add 9x from both sides and subtract 14 from both sides:  -11 = x

x = -11

Answer:

x = -11

Answer: more likely

Step-by-step explanation:

Given that :

Population Mean = 7.4

Population standard deviation = 1.1

Sample mean with a sample size of 30 = 8.1

A sample mean of 8.1 will be more likely with a sample size (N) of 10 because, the sampling distribution gets wider with decreasing sample size and narrower with larger sample sizes, hence, sample mean seems to conform with the population mean when the sample size are very large according to the central limit theorem. Hence, since a sample size of 30 results in a sample mean of 8.1, reducing the sample size will either give a similar sample mean or a sample mean further away from the population mean.

hope that helps and plss let me know if you have any related questions :))

Answer:

coordinates are (8,10)

Step-by-step explanation:

Answer:

a.) 2(2x)+2(4x-3)

b.)2(2x)+2(4x-3)=42

Step-by-step explanation:

b.)2(2x)+2(4x-3)=42

distribute

4x+8x-3=42

add the like terms

12x-3=42

move the -3 by adding to both sides

12x=45

divide both sides by 12

12x/12=45/12

x=3.75

and to make sure it's right, plug x into the equation.

2(2(3.75))+2(4(3.75)-3)=42

now multiply/add/subtract everything.

2x2x3.75=15 (This was the 1st set of parenthesis)

2x4x3.75-3=27 (This was the 2nd set of parenthesis)

15+27=42

42=42

Answer:

5 units

Step-by-step explanation:

Here, we want to find the distance CP

the distance from the center of the circle to the circumference is referred to as radius.

Hence CP is the radius of the circle

Also CN is another radius and also CK is another radius

Thus, mathematically; CN = CK

This means that;

x^2 -20 = 3x -10

x^2 -20 -3x + 10 = 0

x^2 -3x -10 = 0

x^2 -5x + 2x -10 = 0

x(x-5) + 2(x-5) = 0

(x-5)(x+2) = 0

x = 5 or -2

To get CP , we can substitute for x in any of the given expressions

Let’s use 3x-10

Using x = 5

3(5) -10 = 15-10 = 5

Using x = -2

3(-2) -10 = -6-10 = -16

But since length cannot be negative , 5 units is our answer

Answer: it is probably an irrational number

Step-by-step explanation: most exact numbers are rational but most decimal numbers are irrational

Answer:

The number of apples in the 12th bag is 9

Step-by-step explanation:

The Mean Value of a Data Set

The mean or average of a data set is found by adding all numbers and then dividing by the number of values in the set. Written as a formula:

[tex]\displaystyle \bar x=\frac{\sum{x_i}}{n}[/tex]

Where xi is the value of each data and n is the total number of values.

We are given the value of n=12 and the mean number of apples in each bag (8), thus:

[tex]\displaystyle 8=\frac{\sum{x_i}}{12}[/tex]

Multiply by 12

[tex]\sum{x_i}=96[/tex]

This means the sum of all the values is 96. If we add the existing values from the table, considering their frequency, we have:

[tex]6*1+7*4+8*2+9*3+10*1=87[/tex]

Note the sum should be 96, so the 12th bag must have 96-87=9 apples

The number of apples in the 12th bag is 9

Step-by-step explanation:

divide 125 by 4

hope this helps you!!! also good luck!!!!

Answer:

Hey!

Your answer is $31.25

Step-by-step explanation:

To get your value of 1 GAME:

Divide the TOTAL VALUE OF 4 GAMES by 4!

So in this case...

125 ÷ 4 = 31.25

ANSWER: $31.25

(Proof: 31.25 × 4 = 125)

I HOPE THIS HELPS YOU!!

Answer:

W=4 l=16

Step-by-step explanation:

Let w = width

Let l = length

Since the length is 4 times the width, l=4w

Perimeter of rectangle = 2l + 2w

= 2(4w)+2w

=10w

The perimeter of the rectangle =40, so

40=10w and w=4

Plug w into the length equation : l=4w=4(4)=16

Answer:

a. 1/4

Step-by-step explanation:

3r=12p

Divide the left side by 12 to get 1 cup of pineapple juice.

3r=12p

     ----  = p

      12

So now you have

3r=p

BUT you have to divide BOTH sides by 12 so

3r=p

---

12

NOW you have

3/12 r = p

Simplify.

1/4r = p

So 1 cup of pineapple juice is equivalent to a quarter cup of orange juice!

Answer:

The rocket will hit the ground at 64.2 seconds.

Step-by-step explanation:

The time at which the rocket will hit the ground can be calculated using the following equation:

[tex] Y_{f} = Y_{0} + V_{0}y*t - \frac{1}{2}gt^{2} [/tex]

Where:

[tex]Y_{f}[/tex]: is the final height = 0

[tex]Y_{0}[/tex]: is the initial height = 3 ft

[tex]V_{0}[/tex]: is the initial speed = 315 ft/s

t: is the time =?

g: is the gravity = 9.81 m/s²

[tex] 3 + 315*t - \frac{1}{2}9.81*t^{2} = 0 [/tex]        

Solving the above quadratic equation for t, we have the following values:

t₁ = -0.0095 s

t₂ = 64.2 s

Taking the positive value, we have that the rocket will hit the ground at 64.2 seconds.

I hope it helps you!

Answer: Jamar is correct

Step-by-step explanation:

Integer is a number that is a whole number and can either be positive or negative but it can't be a fraction or decimal. e.g 4, -2, 6, -23 etc.

A whole numbers are zero and other natural numbers such as 1, 4, 23. Negative numbers are not part of whole numbers.

From the statement made in the question, Sophia is wrong while Jamar is correct. The numbers aren't all whole numbers because some are negative.
