Multiply

Which one ??? Please help

Answer:

x=2

y=4

You don't need an explanation, do you?

Answer:

584

Step-by-step explanation:

146 adult tickets were sold.

write out your equation first: x+3x=584

4x=584

x=146

Try it out 146+3(146)=584

It worked. That's the solution.

so lets divide the amount of tickets by 4 because there are 4 parts needed in this situation which equals 146 then we know our answer is 146 because the other three parts go to the kids tickets

I don't exactly know this but

Step-by-step explanation:

remeber that descend is subtraction. under

Answer:

a. S = {A,B,AB,O}

b. P(A) = 0.41, P(B) = 0.1, P(AB) = 0.04, P(O) = 0.45

c. 0.45 = 45% probability that the person chosen at random has either type A or type AB blood

Step-by-step explanation:

a List the sample space for this experiment.

All possible blood types(A, B, AB or O). So

S = {A,B,AB,O}

b Make use of the information given above to assign probabilities to each of the simple events.

The proportions of blood phenotypes, A, B, AB, and O, in the population of all Caucasians in the United States are approximately .41, .10, .04, and .45, respectively.

So

P(A) = 0.41, P(B) = 0.1, P(AB) = 0.04, P(O) = 0.45

c What is the probability that the person chosen at random has either type A or type AB blood

P(A) + P(AB) = 0.41 + 0.04 = 0.45

0.45 = 45% probability that the person chosen at random has either type A or type AB blood

Answer:

4 pounds, 14 ounces

Step-by-step explanation:

he said triple = *3

converting all the pounds to ounces, 1 pound is 16 ounces

16+10=26

26*3=78

78/16

4 pounds, 14 ounces

Answer:

the answer is 42

Step-by-step explanation:

Step-by-step explanation:

Use formula

[tex] (\frac{b}{2} ) {}^{2} [/tex]

To add a third new term and factor to find the answer. Example

[tex]x {}^{2} + 6x = 18[/tex]

[tex]( \frac{6}{2} ) {}^{2} [/tex]

Which equal 9. so our equation look like

[tex] {x}^{2} + 6x + 9 = 18 + 9[/tex]

The only number that multiply to 9 and add up to 6 is 3. So we write our equation like this.

[tex](x + 3) {}^{2} = 27[/tex]

Take the sqr root of both sides

[tex]x + 3 = \sqrt{27} [/tex]

Subtract 3 from both sides

[tex]x = \sqrt{27} - 3[/tex]

Since a sqr root of a number can be positive or negative, the answer is

[tex] \sqrt{27} - 3[/tex]

or

[tex] - ( \sqrt{27} ) - 3[/tex]

Answer:

Step-by-step explanation:

a) Volume of small cube box = 8 in³

      side³ = 8 = 2³

Side of small box = 2 in

b)  Side of larger box = 2 + 6 = 8 in

Volume of larger box = 8*8*8 = 512 in³

c) Number of balls to be shipped in the larger box = Volume of larger box ÷ Volume of smaller box

= 512 ÷ 8

= 64 golf balls

Answer:

A   20°

Step-by-step explanation:

Explanation:-

Given graph

The corresponding angles are congruent (equal to each other)

(x+60)° = 4 x°

x + 60 = 4x

4x-x = 60

3x =60

x = 20°

The value of x=20°

Answer:

3/4×100%=75%is the percent equivalent to 3/4

A percent is a value out of 100

Change the fraction

= 3/4 * 25

= 75/100

This fraction represents a percent.

= 75/100

= 75%

Answer:

-1

Step-by-step explanation:

When solving a problem like this, you should do addition and subtraction from left to right. 2 +2 = 4, and 4-5=-1. Hope this helps!

Answer:

The height of the building is of 244.95 feet.

Step-by-step explanation:

We use the Pythagorean Theorem to solve this question.

We have that:

The shadow of 50 feet is one side of the right triangle, while the height h is other side.

The hypotenuse is the distance from the end of the shadow to the top of the building, which is 250 feet.

So

[tex]50^2 + h^2 = 250^2[/tex]

[tex]h^2 = \sqrt{250^2 - 50^2}[/tex]

[tex]h = 244.95[/tex]

The height of the building is of 244.95 feet.

The questions is basically saying make x isolated.

First add 3 to both sides.

y+3=2x-3+3

y+3=2x

Now divide both sides by 2

(y+3)/2=x

x=(y+3)/2

Done!

Answer:

There is significant evidence that Jane has met the requirement.

Step-by-step explanation:

Given that:

μ = 100

μ > 100

Sample size, n = 16

Sample mean, x = 108

Sample standard deviation, s = 12

Level of significance, α = 0.1

Degree of freedom, df = n - 1 = 16 - 1 = 15

Test statistic

T = (x - μ) / s÷sqrt(n)

Tstatistic = (108 - 100) / 12 ÷ sqrt(16)

Tstatistic = 8 / 3

Tstatistic = 2.6667

Using the pvalue calculator :

Tstatistic at 0.1, df = 15 ;

P-value = 0.008799

Since pvalue < α

We reject the Null

The is no significant evidence to conclude that Jane has exceeded an average of more than $100

Answer:

Step-by-step explanation:

Answer:

x = 2 and y = 2

Step-by-step explanation:

The given system of equations are :

12x+8y = 40 ...(1)

4x+5y = 18  ....(2)

Multiply equation (2) by 3.

12x+15y = 54 ...(3)

Subtract equation (1) by (3).

12x+15y-(12x+8y) = 54-40

12x+15y-12x-8y = 14

7y = 14

y = 2

Put the value of y in equation (2).

4x+5(2) = 18

4x+10 = 18

4x = 8

x = 2

The solutions of the given equations are x = 2 and y = 2
