Step-by-step explanation:

Answer:

Answer is 887.4

Step-by-step explanation:

Answer:

27.50(80) is 2,200

2,200-396-175-264= 1,365

I think this is how u do it correct me if I'm wrong

Answer:

65mph

Step-by-step explanation:

Add 100 and 30 together then divide by 2. You get 65 miles per hour.

Mean of a given set of data = Sum of all observations ÷ Total number of observations

Mean of this data set = 88 + 82 + 97 + 76 + 79 + 92 + 65 + 84 + 79 + 90 + 75 + 82 + 78 + 77 + 93 + 88 + 95 + 73 + 69 89 + 93 + 78 + 60 + 95 + 88 + 72 + 80 + 94 + 88 + 74

Mean = 2729 ÷ 30

Median = the middle observation in a given set of data

Median of these test scores = 60 , 65 , 69 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 78 , 79 , 79 , 80 , 82 , 82 , 84 , 88 , 88 , 88 , 88 , 89 , 90 , 92 , 93 , 93 , 94 , 95 , 95 , 97 .

Median = 82 + 82 / 2

= 164 ÷ 2

= 82

Mode = most frequently occurring number in a given set of data .

Mode of these test scores =

= 60 = 1 time

= 65 = 1 time

= 69 = 1 time

= 72 = 1 time

= 73 = 1 time

= 74 = 1 time

= 75 = 1 time

= 76 = 1 time

= 77 = 1 time

= 78 = 2 times

= 79 = 2 times

= 80 = 1 time

= 82 = 2 times

= 84 = 1 time

= 88 = 4 times

= 89 = 1 time

= 90 = 1 time

= 92 = 1 time

= 93 = 2 times

= 94 = 1 time

= 95 = 2 times

= 97 = 1 time

Midrange = average of the largest and smallest number in a given set of data

Midrange of these test scores = 97 + 60 / 2

= 97 + 60 / 2

= 157 ÷ 2

= 78.5

Therefore , the correct option is :-

Answer:

4x - 6 = 24

4x=30

x=7.5

Answer:

<B = <ABC = 107°

Step-by-step explanation:

<CAB = 32° (property of isosceles triangle)

<ACB = 41° (property of isosceles triangle)

<ABC = ?

<ABC + <ACB + < CAB = 180° (sum of angles of triangle)

<ABC + 41° + 32° = 180°

<ABC + 73° = 180°

<ABC = 180° - 73°

<ABC = 107°

Answer:

x = 4

Step-by-step explanation:

First, you subtract 1 from both sides, giving you 3x = x + 8

Then you subtract 1x from both sides, so 2x = 8

Divide the 2 from both sides which leaves you with the answer, x = 4

Answer:

83.3333%

Step-by-step explanation:

The accrued amount of an investment is the original principal P plus the accumulated simple interest, I = Prt, therefore we have:

A = P + I = P + (Prt), and finally A = P(1 + rt)

35% of 80 is 28.

Answer is 80.

Answer:

The quotient is 10x + 16

The remainder is [tex]28x^2 + 10x +22[/tex]

Step-by-step explanation:

Use binomial probability:

P = nCr pʳ qⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1−p).

Given n = 5, p = 0.58, and q = 0.42.

P(0) = ₅C₀ (0.58)⁰ (0.42)⁵⁻⁰ = 0.013

P(1) = ₅C₁ (0.58)¹ (0.42)⁵⁻¹ = 0.090

P(2) = ₅C₂ (0.58)² (0.42)⁵⁻² = 0.249

P(3) = ₅C₃ (0.58)³ (0.42)⁵⁻³ = 0.344

P(4) = ₅C₄ (0.58)⁴ (0.42)⁵⁻⁴ = 0.238

P(5) = ₅C₅ (0.58)⁵ (0.42)⁵⁻⁵ = 0.066

The most likely result is 3 families.

The probability of at least 3 families is:

0.344 + 0.238 + 0.066 = 0.648

Answer:

[tex]m=\frac{9}{7}[/tex]

Step-by-step explanation:

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Simply plug in the 2 coordinates into the slope formula to find slope m:

[tex]m=\frac{-4-5}{-1-6}[/tex]

[tex]m=\frac{-9}{-7}[/tex]

[tex]m=\frac{9}{7}[/tex]

Answer:

2698

Step-by-step explanation:First you take 1000 from 5000 and then distribute it to 395

Answer:

you would subtract 2697 from 5395. you have it in the correct format. the answer would be 2,698.

Step-by-step explanation:

Answer:

x=9.06

Step-by-step explanation:

We have the hypotenuse and we want the opposite of angle a.

so we do

sin65 = x/10.  

Solve for x by simplifying both sides of the equation, then isolating the variable.

Answer:

well when you hear "union" you think 'joined' or 'together' since thats what it means, In a mathmatical set of numbers, union means that both of the sets are necessary for the equation to be true. I'm not sure what the sets are in this problem but in order to get "union" from anything, that means that when you checked for your domains, the values that you got had to be part of both the given sets

Answer:

8

Step-by-step explanation:

Answer:

at least 8 gallons

Step-by-step explanation:

Answer:

This is because it is easier this way.

You avoid the problem of putting an element in one set and then realizing that the element also belongs to another set, then you must erase something in order to put the element in both sets. Starting with the intersection allows you to know where will be each set in the diagram, and in this way, the diagram should end up being more readable or "clean".

This may seem small, but being "clean" when doing math, will allow you to have an easier time dealing with a lot of problems. And also will be easier for other people when reading your equations and such.
