Answer:

74.15

Step-by-step explanation:

this is bc there are ten spaces between 74.1 and 74.2. halfway between that is another 00.05 points.

Answer:

74.15

Step-by-step explanation:

you can find the average, by adding 74.1 and 74.2 and dividing by 2, which would get you 74.15

you can look on a number line and find the midpoint that way

Answer:

The answer is:

u = 7

Step-by-step explanation:

7 x 1 = 7

7 x u = 7u

So..

u = 7

Answer:

The correct options are;

1) The mean (average) score for each class is the SAME

2) The variance of Class B is 159.14

3) Class B has a greater spread

4) Based on the data A score of 8 is more likely in class B than in class A

Step-by-step explanation:

The given data are;

For the 1st period (Class A), we have

The mean, μ = (10 + 15 + 20 + 25 + 30 + 35 + 40)/7 = 175/7 = 25

The standard deviation σ, is given as follows;

[tex]\sigma =\sqrt{\dfrac{\sum \left (x_i-\mu \right )^{2} }{N}}[/tex]

Where;

N = The number population size = 7

[tex]x_i[/tex] = The individual data values

Solving using Microsoft Excel formula STDEV.P gives, σ = 10

[tex]\sigma _A[/tex] ≈ 10

The variance = σ² = 10² = 100

For the 2nd period (Class B), we have

The mean, μ = (7 + 12 + 17 + 25 + 33 + 38 + 43)/7 = 175/7 = 25

The standard deviation σ, is given as follows;

[tex]\sigma =\sqrt{\dfrac{\sum \left (x_i-\mu \right )^{2} }{N}}[/tex]

Where;

N = The number population size = 7

[tex]x_i[/tex] = The individual data values

Solving using Microsoft Excel formula STDEV.P gives, [tex]\sigma _B[/tex] ≈ 12.615

[tex]\sigma _B[/tex] ≈ 12.615 > [tex]\sigma _A[/tex] ≈ 10, class B has greater spread

The variance = σ² = 12.615² ≈ 159.14

A score of 8 is more likely in class B than in class A due to the availability of data before and after the a score of 8

Answer:

They need to earn 6 yards on the fourth down to have a 10 yard gain from their starting position

Step-by-step explanation:

A football team gained 6 yards on the first​ down, lost 19 yards on the second​ down,

Total gained yards:

6 - 19 = -13 yards

So at the end of 2nd down the team lost 13 yards.

They gained 17 yards on the third down.

-13 + 17 = 4

So at the end of 3rd down the team gained 4 yards.

They want 10 yard gain at the end of 4th down.

If they gain 6 yards in the 4th down then the sum will be 10 yards

4 + 6 = 10

Hence, they need to earn 6 yards on the fourth down to have a 10 yard gain from their starting position.

Step-by-step explanation:

let x be the missing side length.We know that hypotenuse is 2x because x is opposite the 30 angle.

Using pythagorean theorem we have that x^2+9^2=(2x)^2

81=4x^2-x^2

81=3x^2

x^2=81/3=27

x=√27

so the missing side is √27

Answer:

1. The independent variable is a and the dependent variable is m

2. The domain is discrete

Step-by-step explanation:

let us explain the difference between discrete or continuous domains

Discrete domain: It is a set of input values that consists of only certain numbers in an interval.

Continuous domain: It is a set of input values that consists of all numbers in an interval.

In the question

m = 3a, where

m is the amount of money m in dollars

Each customer can buy a maximum of three apps

1.

∵ m is depended on the value of 3a

∴ m is the dependent variable ⇒ (output)

∴ a is the independent variable ⇒ (input)

∴ The independent variable is a and the dependent variable is m

2.

∵ The domain the input values

∴ Each customer can buy a maximum of three apps

→ That means it is a certain numbers

∴ The domain is discrete

Answer:

I think its b because is says loosing 1/4 lbs each week. That would be subtraction. The others are adding.

The equation that represents two Gorillas weighing the same is,

B. 135 + (1/2)x = 143 - (1/4)x.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, A mountain gorilla weighs 135 pounds and is gaining 1/2 pound each week and an eastern gorilla weighs 145 pounds and is losing 1/4 pound each week.

The weights of the two Gorillas will be the same when we'll equate their individual equations which is,

135 + (1/2)x = 143 - (1/4)x.

Solving for 'x' would give us the number of weeks required for two Gorillas

to weigh the same.

Step-by-step explanation:

Answer:

x = -1

Step-by-step explanation:

2(x – 2) + 6 = 0

~Distribute left side

2x - 4 + 6 = 0

~Combine like terms

2x + 2 = 0

~Subtract 2 to both sides

2x = -2

~Divide 2 to both sides

x = -1

Answer:

(3x + 5)(2x - 3) = 6x² + x - 15

Step-by-step explanation:

To find the product of two binomials, we could use the FOIL method.

First

Outer (Outside)

Inner (Inside)

Last

(3x + 5)(2x - 3) = (3x)(2x) + (3x)(-3) + (5)(2x) + (5)(-3) = 6x² - 9x + 10x - 15 = 6x² + x - 15

So the product of the two binomials would be 6x² + x - 15.

I hope you find my answer and explanation to be helpful. Happy studying.

Answer:

Step-by-step explanation:

The age of three sisters are consecutive integers meaning they are only one year apart.

E.g. sister 1 = x yrs old

Sister 2 = (x + 1) yrs old

Sister 3 = (x + 2) yrs old

They have a sum of 180 meaning if you add all 3 of their ages, you get a total of 180.

Sister 1 + sister 2 + sister 3 = 180

x + (x + 1) + (x + 2) = 180

So gather the like terms and you get:

3x + 3 = 180

Subtract 3 from both sides

3x = 180-3 = 177

Solve for x by dividing both sides by 3.

x = 177/3 = 59

So now we know what x is so you just plug it back into the equations at the beginning for the ages of each of the sisters.

Sister 1 = x = 59

Sister 2 = x + 1 = 59 + 1 = 60

Sister 3 = x + 2 = 59 + 2 = 61

Answer:

x= -4

Step-by-step explanation:

1. Expand the brackets (multiply everything inside by the number outside):

5x + 15= 2x + 3

2. Move all of the x terms to one side and all of the number terms to the other:

Subtract 2x from both sides

5x-2x + 15= 2x-2x + 3

3x + 15= 3

Subtract 15 from both sides

3x + 15- 15= 3 - 15

3x= -12

3. Solve for x:

x= -12/3

x= -4

The gcd of 35 and 5 is 5, so 35/5 = (5×7)/(5×1) = 5/5×7 = 7:

7 + 3 (30 - 3^3 + 1)

Answer:

0.946 liters

Step-by-step explanation:

since the fourth decimal place is below 5, you would not round up the thousandths. also, the thousandths is the third decimal place (tenths, hundredths, thousandths).

Answer:

10y° = 130°

(4x - 22)° = 50°

(7x + 4)° = 130°

(3y + 11)° = 50°

Step-by-step explanation:

From the picture attached,

Two lines are intersecting each other at a pint making two pairs of vertical angles.

By definition, pair of vertical angles are equal in measure.

10y° = (7x + 4)° [Vertical angles]

-7x + 10y = 4 -----(1)

(3y + 11)° = (4x - 22)° [Vertical angles]

-4x + 3y = -33 ------(2)

[Equation (1) × 3] - [Equation (2) × 10]

(-21x + 30y) - (-40x + 30y) = 12 + 330

-21x + 40x = 342

19x = 342

x = [tex]\frac{342}{19}=18[/tex]

From equation (1),

-7(18) + 10y = 4

-126 + 10y = 4

10y = 130

y = 13

Therefore, 10y° = 130°

(4x - 22)° = 50°

(7x + 4)° = 130°

(3y + 11)° = 50°

Answer:

Answer:

Honda made 32 cars

Step-by-step explanation:

Total no. of cars = 60

car made by ford = 3/10 of total no of cars

car made by ford = 3/10 of 60 = 3/10* 60 = 18

car made by General Motors = 1/6of total no of cars

car made by General Motors = 1/6 of 60 = 1/6* 60 = 10

No of cars made by Honda = Total no. of cars - car made by ford - car made by General Motors

No of cars made by Honda = 60 - 18 - 10 = 32

In this lot, Honda made 32 cars.
