Answer:

21%

Step-by-step explanation:

8+7+8+6+6= 35 total marbles

35-2 used = 33 marbles left

100/33 = 3% per marble

7 yellow left x 3 % = 21%

Answer:

7/25

Step-by-step explanation:

Let's remove all the marbles that were drawn by the bag first. That makes...

Red: 6

Blue: 6

Purple: 6

Yellow: 7

If we have 7 yellow marbles currently in a bag of 25 marbles, then the chance that the third student draws a yellow is...

Answer:

B. 130

Step-by-step explanation:

_______________

Answer:

B - 130

both values are equal to 20.8

Step-by-step explanation:

the first step is figuring out what they want you to compare the multiple choice answers to- 13% of 160, which is equal to 20.8 (160*.13)!

so next, we need to take 16% of each of our answers. we can guess at what our answer isn't going to be, specifically that it cannot be 13 since 20.8 is more than 13. We can also guess its not going to be 13,000, since even ten percent of that is about 130. The same logic can be applied to 1300, ten percent of 1300 (ie dividing 1300 by ten) is 130, again too large.

Therefore, by process of elimination we can guess that its likely B.

As for checking: we have our 20.8 to compare to, and 16% of 130 (.16*130) is in fact 20.8.

16% of 130, or .16*130 is equal to 20.8

Answer:He will pay $9.50 for each shirt plus a one-time fee of $22.50 for the design.

Which equation can be used to find y, the total cost to buy x shirts?

A) y = 9.5x + 22.5

B) y =22.5x + 9.5

C) y = 9.5x - 22.5

D) y =22.5x - 9.5

He would use equation A.

Step-by-step explanation:If each shirt cost 9.50 you would multiply that by how many shirts you have plus the one time fee of 22.50 you would get the equation y= 9.5x + 22.5

Answer:

C. the graph of f(x) +K

Step-by-step explanation:

C is the only graph with a y = 3

Answer:

y=2x-5

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(3-1)/(4-3)

m=2/1

m=2

y-y1=m(x-x1)

y-1=2(x-3)

y=2x-6+1

y=2x-5

Answer:

y = mx+b

Answer:

Based on the confidence interval, Sheldon's claim is plausible

Step-by-step explanation:

The number of customers in the sample, n = 620 customers

The number of customers that replied that they had moved at least once in the last five years = 201 (32.4%)

The 90% confidence interval for the sample = (0.293, 0.355)

Let 'p' represent the proportion of all customers who have moved in the past five years

The proportion of customers Sheldon claimed have moved in the past five years, p > 1 in 4 (0.25)

The proportion Zachary urges Sheldon to claim is, p > 1 in 3 (0.[tex]\overline 3[/tex])

Given that the lower estimate of the confidence interval is 0.293 (>0.25) and upper bound of the confidence interval is 0.355 (> 0.[tex]\overline 3[/tex]), and that 0.26 in also more than 1 in 4 but less than 0.293, but however that 0.293 which is within the 90% confidence interval is less than 0.[tex]\overline 3[/tex] or 1 in 3, as opposed to what Zachary urges Sheldon to claim, Sheldon's claim is more plausible.

Answer:D

Step-by-step explanation:

Answer:

Principal, P = $23675.90

Step-by-step explanation:

Given the following data;

Interest rate = 2.2 %

Future value = $27000

Time = 6 years

Number of times = 365 days

To find the principal amount, we would use the compound interest formula;

[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

n is the number of times the interest is compounded in a year.

t is the number of years for the compound interest.

Substituting into the equation, we have;

[tex] 27000 = P*(1 + \frac{0.022}{365})^{365*6}[/tex]

[tex] 27000 = P*(1 + 0.000060)^{2190}[/tex]

[tex] 27000 = P*(1.000060)^{2190}[/tex]

[tex] 27000 = P*(1.1404)[/tex]

[tex] P = \frac {27000}{1.1404} [/tex]

Principal, P = $23675.90

Answer:

option A all real numbers

Step-by-step explanation:

domain is the all possible "X" values

and X has all real values

All the real numbers of X are domain and range of piecewise function .

What is piecewise function?

A Piecewise Function is a merge of several functions in a single graph. Each function takes a part of the x axis of the graph.

Graph

Domain: The domain of a piecewise-defined function is the union of its subdomains.

Range :The range of a piecewise-defined function is the union of the ranges of each subfunction over its subdomain.

Now,

Thus  the domain and range of piecewise function is all real numbers .

Answer:

Perimeter of triangle= sum of two sides and hypotenuse

Answer:

30 units

Step-by-step explanation:

The perimeter of the triangle is the sum of the two legs, or the shorter sides a and b, and the hypotenuse, the last and longest side, c.

We can already see that side a and b have the lengths of 5 and 12 units.

To find the length of c, use the formula a² + b² = c².

Substitute our a and b values into the formula and solve for c.

a² + b² = c²

5² + 12² = c²

25 + 144 = c²

169 = c²

√169 = √c²

13 = c

The third side is 13 units long.

Now we can add our values for a, b, and c together to find the perimeter.

5 + 12 + 13 = P

30 = P

The perimeter is 30 units.

Answer:

12.5%

Step-by-step explanation:

Previous grams of protein = 48g

Present grams of protein = 54g

By what percentage did Amanda increase the amount of protein she eats?

Percentage increase in the amount of protein = (present grams - previous grams) / previous grams × 100

= (54g - 48g) / 48g × 100

= 6g/48g × 100

= 1/8 × 100

= 0.125 × 100

= 12.5%

Percentage increase in the amount of protein = 12.5%

Answer:

No, you can not create a triangle with these three side lengths.

Step-by-step explanation:

According to the Triangle Inequality Theorem, in order for three given lengths to form a triangle, two of the side lengths must add up to be greater than the length of the largest length. 16+37 makes 53, which is equal to the length of the largest side, not greater.

Step-by-step explanation:

Cost per slice

3.75 / 3 = 1.25

Cost of 4 slices

1.25 * 4 = 5

Answer:

$5

Step-by-step explanation:

First, find how much one slice of pizza costs.

Divide Mario's total by the number of slices he got:

3.75/3

= 1.25

So, one slice of pizza costs $1.25

Add this to his total to find how much his bill will be with one more slice:

3.75 + 1.25

= 5

So, his bill will be $5
