Answer:

A and E.

Step-by-step explanation:

Using the math from 7th grade, 6 rooted is 36/9=4+10 is 14. Everything else you must multiply everything in parenthesis, by the outside number, then you add them. E is right because -15+35=20-6=14. Yw.

What is the equation of this graphed line?

Eva8 [605]

Answer:

y = -9/8x + 7

Step-by-step explanation:

Slope-intercept form is:

y = mx + b

Points given:

(0, 7) and (8, -2)

y-intercept is

b = 7 as per the first point

And the slope is:

m = (-2 - 7)/(8 - 0) = -9/8

So the line is:

y = -9/8x + 7

Can someone solve and explain how to do these absolute equations for 40 points? I'll give brainliest to the best correct answer.

irga5000 [103]

Answer:

Explanation Below

Step-by-step explanation:

1. -4 + | x - 1 | = 3

= -4 + | x - 1 | + 4 = 3 + 4

= | x - 1 | = 7

= x - 1 = -7 or x - 1 = 7

= x = -6 or x = 8

2. 6 + 4 | 2x + 6| = 14

= 6 + 4 | 2x + 6 | - 6 = 14 - 6

= 4 | 2x + 6 | = 8

= 4 | 2x + 6 | / 4 = 8/4

= 2x + 6 = -2 or 2x + 6 = 2

= x = -4 or x = -2

3. -10 + | -6 - x | = 1

= -10 + | -6 + x | + 10 = 1 + 10

= | -6 - x | = 11

= -6 - x = -11 or -6 - x = 11

= x = -17 or x = 5

4. | 7 - 2x | + 4 = 5

= | 7 - 2x | + 4 - 4 = 5 - 4

= | 7 - 2x | = 1

= 7 - 2x = -1 or 7 - 2x = 1

= x = 3 or x = 4

Here are the Steps:

SOLVING EQUATIONS CONTAINING ABSOLUTE VALUE(S)

Step 1: Isolate the absolute value expression.

Step2: Set the quantity inside the absolute value notation equal to + and - the quantity on the other side of the equation.

Step 3: Solve for the unknown in both equations.

Step 4: Check your answer analytically or graphically.

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
