Answer:

It is given that Tawanna is asked to find the GCF of each term in the expression 2ab+8b.

Firstly she should find the factors of each term in the expression as :

2ab=1,2,a and b

8b=1,2,4,8 and b

Now, GCF is the greatest common factor, since the GCF of the above terms is 1,2 and b, thus she should use each common factor once.

She wrote the common factors twice which is the error in her solution, thus she should use each common factor once.

Brainliest + Points Can you please explain why choice A. is correct?

tankabanditka [31]

Answer: because that is what the slope would look like

Step-by-step explanation:

when you graph this, you have a point at 2, 4 and 0, 8. when you go to 0, 8 and count down four so you now have to move to the right to get to 2, 4. You then move to the right 2 spaces. so, you moved (-4, 2) since this can be simplified, you then have (-2, 1) which is equal to -2. If this still doesnt make sense, go to Desmos.com and put (2,4) click the plus button then add expression then type (0,8). Count down -4 and over 2. Hope this helps

An alarming number of U.S. adults are either overweight or obese. The distinction between overweight and obese is made on the ba

sladkih [1.3K]

Answer:

(a) The probability that a randomly selected adult is either overweight or obese is 0.569.

(b) The probability that a randomly selected adult is neither overweight nor obese is 0.431.

Step-by-step explanation:

Let A = a person is over weight and B = a person is obese.

The information provided is:

An adult is considered overweight if the BMI ≥ 25 but BMI < 30.

An obese adult will have a BMI ≥ 30.

According to the range of BMI the events A and B are independent.

P (A) = 0.331 and P (B) = 0.357.

(a)

Compute the probability that a randomly selected adult is either overweight or obese as follows:

P (A ∪ B) = P (A) + P (B) - P (A ∩ B)

= P (A) + P (B) - P (A)×P (B)

$=0.331+0.357-(0.331\times0.357)\\=0.569833\\=0.569$

Thus, the probability that a randomly selected adult is either overweight or obese is 0.569.

(b)

Compute the probability that a randomly selected adult is neither overweight nor obese as follows:

$P(A^{c}\cup B^{c})=1-P(A\cup B)=1-0.569=0.431$

Thus, the probability that a randomly selected adult is neither overweight nor obese is 0.431.
