Answer and Step-by-step explanation:

We are not given the function in question, but in order to explain, will form a function. Suppose f(x) = 3x + 2.

If f(x) = 17, then

3x + 2 = 17, to find the value of x, we have solve for x in the equation.

3x = 17 – 2

3x = 15

x = 5

This is the method that can be used to solve problems of this nature.

The probability that a person in the United States has type B+ blood is 12%. Three unrelated people in the United States are s

V125BC [204]

Answer:

The probability that all three have type B+ blood is 0.001728

Step-by-step explanation:

For each person, there are only two possible outcomes. Either they have type B+ blood, or they do not. The probability of a person having type B+ blood is independent of any other person. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

The probability that a person in the United States has type B+ blood is 12%.

This means that $p = 0.12$

Three unrelated people in the United States are selected at random.

This means that $n = 3$

Find the probability that all three have type B+ blood.

This is P(X = 3).

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 3) = C_{3,3}.(0.12)^{3}.(0.88)^{0} = 0.001728$

The probability that all three have type B+ blood is 0.001728

Solve 2m-3-5= -m+10 PLEASE PLEASE PLEASE ANSWER

Vlad [161]

Solve for m:
2 m - 5 - 3 = 10 - m

Subtract like terms. -3 - 5 = -8:
2 m - 8 = 10 - m

Add m to both sides:
2 m + m - 8 = (m - m) + 10

m - m = 0:
2 m + m - 8 = 10

2 m + m = 3 m:
3 m - 8 = 10

Add 8 to both sides:
3 m + (8 - 8) = 8 + 10

8 - 8 = 0:
3 m = 10 + 8

10 + 8 = 18:
3 m = 18

Divide both sides of 3 m = 18 by 3:
(3 m)/3 = 18/3

3/3 = 1:
m = 18/3

The gcd of 18 and 3 is 3, so 18/3 = (3×6)/(3×1) = 3/3×6 = 6:
Answer: m = 6
