To find the answer to this question you divide 26 by 2. You do this because the x and the 2 are next to each other meaning they are being multiplied. Also if two numbers are like this- 2(x) this also means they are being multiplied. But if the 2 is a tiny number on the top right side of x that means you do (x multiplied by x). Just make sure it's x(2) and not x^2. You will get two different answers.
If it's x(2)= 26 the answer is 13. (26 ÷ 2= 13)
But if the question is x^2= 26 you will get something different.
Hope I helped!

Explain why an organism grows in size when its cells can only achieve a certain size.Write your answer in the essay box

ArbitrLikvidat [17]

Answer:

An organism keeps growing because it's cells multiply. Cells are only meant to be a certain size yes but they're also meant to duplicate. For example cancer cells, they only grow so big but then they duplicate causing the tumor to grow bigger. Does that make sense?

To serve 1 person at a local restaurant it takes 10 minutes to serve 5 people it takes 18 minutes what is the point slope form

zhannawk [14.2K]

Answer:

$y-1=\frac{1}{2}(x-10)$

Step-by-step explanation:

Let

x------>the time in minutes

y----> the number of people

we know that

The equation of the line into point slope form is equal to

$y-y1=m(x-x1)$

we have

$A(10,1),B(18,5)$

Find the slope

$m=\frac{5-1}{18-10}$

$m=\frac{1}{2}\frac{people}{minutes}$

with the slope m and the point A find the equation of the line

$y-1=\frac{1}{2}(x-10)$ -----> point slope form

Suppose the probability of a false positive result on a mammogram is 4%. Suppose that the probability of a false negative result

Mariulka [41]

Answer:

0.0049 = 0.49% probability that she actually has breast cancer

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

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

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Positive test result

Event B: Breast cancer

Probability of a positive test result:

4% of (1 - 0.0002)

98% of 0.0002

So

$P(A) = 0.04*(1 - 0.0002) + 0.98*0.0002 = 0.040188$

Having breast cancer and testing positive.

98% of 0.0002

So

$P(A \cap B) = 0.98*0.0002 = 0.000196$

What is the probability that she actually has breast cancer?

$P(B|A) = \frac{0.000196}{0.040188} = 0.0049$

0.0049 = 0.49% probability that she actually has breast cancer
