Answer:
[tex]\boxed{x=-25}[/tex]
Step-by-step explanation:
[tex]\frac{2}{7} (x+4)=-6[/tex]
→ Multiply everything by 7 to get rid of the fraction
[tex]2(x+4)=-42[/tex]
→ Expand the bracket
[tex]2x+8=-42[/tex]
→ Minus 8 from both sides to isolate 2x
[tex]2x=-50[/tex]
→ Divide both sides by 2 to isolate x
[tex]x=-25[/tex]
In the general population, one woman in eight will develop breast
cancer. Research has shown that 1 woman in 600 carries a mutation of
the BRCA gene. Eight out of 10 women with this mutation develop
breast cancer.
a) Find the probability that a randomly selected woman will develop
breast cancer given that she has a mutation of the BRCA gene. b) Find the probability that a randomly selected woman will carry the mutation of the BRCA gene and will develop and will develop breast cancer? c) are the events of carrying this mutation and developing Brest cancer independent or dependent?
Answer:
a) 8/10
b) [tex]0.001 \overline{33}[/tex]
c) Independent events
Step-by-step explanation:
The given information are;
The proportion of women than carries a mutation of the BRCA gene, P(A) = 1/600
The proportion of women in which the mutation develops breast cancer, P(B) = 8/10
a) The probability that a randomly selected woman will develop breast cancer given that she has a mutation of the BRCA gene is given as follows;
1 × P(B) = 1 × 8/10 = 8/10
b) The probability, P that a randomly selected woman woman will carry the mutation of the BRCA gene and will develop breast cancer is given as follows;
P(A) × P(B) = 1/600×8/10 = 1/750 = [tex]0.001 \overline{33}[/tex]
c) The events are dependent
Given that P(A) × P(B) = P(A∩B), the events of carrying the mutation and developing Breast cancer are independent events.

A line with a slope of -2 passes through the point (-2,-3). What is the equation of this line?
Answer:
y = - 2x - 7
Step-by-step explanation:
Step 1:
y = mx + b Slope Intercept Form
Step 2:
y = - 2x + b Input Slope
Step 3:
- 3 = - 2 ( - 2 ) + b Input x and y
Step 4:
- 3 = 4 + b Multiply
Step 5:
- 7 = b Subtract 4 on both sides
Answer:
y = - 2x - 7
Hope This Helps :)
m = -2
y = mx +c
-3= -2(-2) +c
-3 =4 + c , c = -7
Thus, equation is y = -2x-7

What integers are closest to the square root of 54 on the number line?
Answer:
sqrt(54) is between 7 and 8
Step-by-step explanation:
Lets look at integers that are squared
1^2 = 1
2^2 = 2
3^2 = 9
4^2 = 16
5^2= 25
6^2 = 36
7^2 = 49
6^2 =64
54- 49 = 5 and 64 - 54 = 10
So 54 is closer to 49
so sqrt(54) is closer to the sqrt(49) = 7
sqrt(54) is between 7 and 8
In order to compete successfully, a producer must produce goods that are
more expensive than those of competitors.
of a lesser quality than those of competitors.
of a higher quality than those of competitors.
created without worrying about the costs of production.
Answer:
of a higher quality than those of competitors.
Step-by-step explanation:
To compete successfully, a producer should ensure that they must produce goods that are of a higher quality than those of their competitors.
The quality of a product is usually a deterministic characteristic of how the public will receive such material.
A quality good produced gives consumers better value for money spent in procuring them. This will ensure a high reliability on the part of the consumers towards the producers. Even at higher prices, most consumers will crave for a good and quality product since they are rest assured of getting maximum value from it.Therefore, a higher quality of goods produced will make a producer compete more successfully.
Answer:
C) Of a higher quality than those of competitors.

Savannah paid $100 to join a music club. She then pays $1.00 per music download. Dominic joined a club for $25 but pays $2.50 per download. Determine the
number of downloads when the cost will be the same
Answer:
It would take 10 downloads
Step-by-step explanation:
Answer:
32 for Dominic and 5 for Savannah
Step-by-step explanation:
You can figure this out by first determining how many downloads Dominic has to make in order to have the total price equal to what Savannah paid just to join the club.
So Savannah paid $100 to join. Dominic only paid $25. So Dominic can spend $75 for downloads before he even gets up to what Savannah paid. Now you can figure out that it will take 30 downloads at $2.50 each to get to that $75.
You could say that Dominic is now equal to Savannah with both spending $100. Dominic would have made 30 downloads and Savannah would have 0. But I believe they want you to go a step further.
So now you just need to look at how many more downloads Dominic would have to make to get to an even full dollar amount. One more download would take him up to $102.50. A second additional download would take him to $105. Savannah would then only have 5 downloads for a total cost of $105 and Dominic would now have a total of 32 downloads for a total of $105.
I think x is 122
y is 58
z is 122
Did I mess it up? Can I get checked?
Answer:
You are correct!
Step-by-step explanation:
Hi!
You are right! If y is in the same spot as 58 degrees, then y is 58 degrees as well! Same goes for x. If z is 122 degrees, then x must be 122 degrees! Great job figuring this one out!
