Answer:

Number the boxes on the left 1–8 from top to bottom. Then their correct order on the right is 3, 7, 8, 4, 6, 5, 2, 1

Step-by-step explanation:

Trade the cube root for a 1/3 power:

(875x^5y^9)^(1/3)

Distribute the 1/3 power:

(125·7)^(1/3)·x^(5/3)·y^(9/3)

Further distribute the powers, rewrite the improper fractions:

125^(1/3)·7^(1/3)·x^(3/3+2/3)·y^3

Write 125 as a cube and simplify 3/3:

(5^3)^(1/3)·7^(1/3)·x^(1+2/3)·y^3

Simplify the cube root of a cube and the x term:

5·7^(1/3)·x·x^(2/3)·y^3

Group the terms with fractional exponents:

5·x·y^3·(7^(1/3)·x^(2/3))

Factor out the 1/3 exponent:

5xy^3·(7x^2)^(1/3)

Trade the 1/3 exponent for a cube root symbol:

5xy^3·∛(7x^2)

Steven has a counter that is yellow on one side and blue on the other. The counter is shown below:

mihalych1998 [28]

In this situation, it is similar to a coin flip, so think about flipping a 2 sided chip, one side colored yellow the other blue, flipping the chip will result in a 50/50 chance for it to land on either side, so no matter how many times you flip it it will always be a 1/2 chance of it being on one of the sides

The National Cancer Institute estimates that 3.65% of women in their 60s get breast cancer. A mammogram can typically identify c

masha68 [24]

Answer:

39.17% probability that a woman in her 60s who has a positive test actually has breast cancer

Step-by-step explanation:

Bayes Theorem:

Two events, A and B.

$P(B|A) = \frac{P(B)*P(A|B)}{P(A)}$

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.

In this question:

Event A: Positive test.

Event B: Having breast cancer.

3.65% of women in their 60s get breast cancer

This means that $P(B) = 0.0365$

A mammogram can typically identify correctly 85% of cancer cases

This means that $P(A|B) = 0.85$

Probability of a positive test.

85% of 3.65% and 100-95 = 5% of 100-3.65 = 96.35%. So

$P(A) = 0.85*0.0365 + 0.05*0.9635 = 0.0792$

What is the probability that a woman in her 60s who has a positive test actually has breast cancer?

$P(B|A) = \frac{0.0365*0.85}{0.0792} = 0.3917$

39.17% probability that a woman in her 60s who has a positive test actually has breast cancer

andrezito [222]

Answer:

Step-by-step explanation:

I think below is your full question:

<em>Erin and Dan went shopping at their local store. Erin bought shirts that cost $12 each and spent $18 on accessories. Dan bought the same number of shirts as Erin for $16 each and spent $10 on accessories. </em>

<em>If Erin and Dan were billed the same amount by the store, how many shirts did each of them buy?</em>

Here is my answer

Let x is number of shirts

Person COST

ERIN 12x+18

DAN 16x+10

Equally Billed 12x+18=16x+10 <=> x = 2

so each of them buy 2 shirts
