From a sample tray, 4 out of the last 10 cake samples chosen were strawberry. based on past data, of the next 20 samples taken, how many you should expect to be pieces of strawberry cake?

The volume of a cylinder is the amount of space in it

The radius of the cylinder is 3 feet

The volume of a cylinder is:

[tex]V = \pi r^2 h[/tex]

Where r represents the radius, and h represents the height

So, we have:

[tex]108\pi = \pi r^2 * 12[/tex]

Divide both sides by 12pi

[tex]9 = r^2[/tex]

Take the square roots of both sides

3 = r

Rewrite as:

r = 3

Hence, the radius of the cylinder is 3 feet

D. Subtraction Property of Equality

Step-by-step explanation:

D. Subtraction Property of Equality

From 6-7, you subtract 132 from both sides. You can only do this because of the subtraction property of equality which essentially means that if you subtract something from one side of the equation, you also have to subtract it from the other side. In this case, you subtract 132 from both sides, therefore it is D.

Answer:

If P(x) has the roots -11 and 6, then its multipliers can be written as

Step-by-step explanation:

P(x)=(x+11)(x-6)

P(x)=x2-6x+11x-66

Answer:

20 + 6x

$44

Step-by-step explanation:

So 5 CD's for 20 dollars is $4 ea. then each one added will be +6 with the variable (x).

so you can't have the first 5 becuase x is used for every one OVER 5.

So

$ or price = 20 + 6x

plug 4 in because 9-5 = 4

20 + 6(4)

20 + 24

Answer:

9) y=(-6-3x)/2                 10) y=(2x+15)/3            11) y=8+4x

12) y=1/2x+6                   13) y= (8-3x)/-4            14) y= (10-6x)/-2

Step-by-step explanation:

The methods I used are known as float and ping, and escalator:

9) We can float the 3x to the other side to make

2y=-6-3x

We now escalate the 2 down to make:

y= [tex]\frac{-6-3x}{2}[/tex]

10) We simply escalate the 3 down to give:

y= [tex]\frac{2x+15}{3}[/tex]

11) We simply float the -4x to the other side:

y=8+4x

12) For this question, it will be better to expand the bracket first:

y-8=-1/2x-2

Now we float the -8 to the other side to give:

y=-1/2x-2+8

Which can be simplified to give:

y=1/2x+6

13) We simply float the 3x to the other side to give:

-4y=8-3x

Now we escalate the -4 down to give:

y= [tex]\frac{(8-3x)}{-4}[/tex]  
14) We float the 6x to the other side to give:

-2y=10-6x

Now we escalate the -2 down to give:

y= [tex]\frac{10-6x}{-2}[/tex]

Answer:

[tex]x = 14 - 3[/tex]

Step-by-step explanation:

*The key word 'less than' means to subtract.

x + 3 = 14 is incorrect. Kiran isn't adding weight to his backpack.

In other words, the backpack didn't increase in pounds.

3(x) = 14 is incorrect. Multiplying is irrelevant to this problem, it's not saying Kiran's backpack is 3 times a number equal to Clare's backpack weight.

x = 143 is incorrect. This equation is unrealistic.

x = 14 - 3 is correct. This equation is explaining that Kiran's backpack is 3 pounds less than Clare's backpack (14)

Answer:

5 if the value of y become 5 it makes this true

Hi! Let's solve this inequality!

Move 12 to the right side, using the opposite operation.

y>17-12

y>5

Thus, any value of y greater than 5 will make this inequality true.

Let's try 6, since 6 is greater than 5.

12+6>17

18>17

Yeah, it worked :)

Thus, any value of y greater than 5 will make this inequality true.

Hope it helps!

Probabilities are used to determine the chances of events

The probability that the salesman left his sunglasses in the first store is 0.16

The given parameter is:

p = 1/5 ---- the probability that he left his sunglass

The probability that he did not leave his sunglass would be:

q= 1- 1/5

Evaluate the difference:

p = 4/5

So, the probability that the salesman left his sunglasses in the first store is:

Pr = 1/5 * 4/5

Evaluate the product

Pr = 4/25

Express as decimal

Pr = 0.16

Hence, the probability that the salesman left his sunglasses in the first store is 0.16

Answer:

What math level is this?

Answer:

21

Step-by-step explanation:

On the left side, 2 multiply by 3 is 6. So you can do the same thing to the right side. 7 multiply by 3 is 21.

Step-by-step explanation:

First problem looks right. Although he started with 145, not 25. Savings and checking combined is the total amount of cash he had before he started working, which is why it's added to the total amount of money he has.

He saves 55 every week. because the multiplier on w, which is weeks is 55. So for every week 55 is added to the multiplication. Ex 2 weeks is 110, 3 is 165, 4 is 220 etc..

He wanted a total of 650 usd. Doesn't matter where it is the total is what matters. Doesn't matetr if hes spending,  storing or even burning the money..
So first make 55w+145=650 then solve

Minus 145 from both sides

55w = 505

About 9 weeks one day and 6 hours. This is a rough estimate since the answer is 9.18181818 weeks.

Answer:

y = 2x + 1 --> linear

y = -4x + 7 --> non-linear

Not a solution for a linear system.

Step-by-step explanation:

for (a), y = 2x+1, substitute the x and y values. keep in mind, that in a linear pair, (x, y). So, for the first equation you get:

7 = 2x3 + 1. This is correct, because 6 + 1 is 7. Therefore, (a) is linear.

for (b), we have to substitute our values again. You get:

7 = -4x3 + 7, which is

7 = -12+7, which is not true. So, (b) is not linear.

This means that for the linear pair (3, 7), it does not satisfy both equations, which means that it is not a solution for the linear system.
