Answer:

20

Step-by-step explanation:

to find x, divide 80 by 4, and you can check your answer two ways after.

Way #1 - insert your answer into x, and see if it works. (80/20=4)

Way #2 - multiply your answer by 4 and see if it equals 80 (20*4=80)

Solve the inequality 4y + 3 > 24 + 14.
Degger [83]
Hi there!

Solving th' Inequality :-

4y + 3 > 24 + 14

=> 4y + 3 > 38

=> 4y > 38 - 3

=> 4y > 35

=> y > \dfrac {35}{4}

=> y > 8.75

Therefore, all real number y which are greater than 8.75 are the solutions of th' given Inequality.

Hence,
Solution of the following Inequality is : ( 8.75, ∞ )

Find m26 if m/1 = 112°
kati45 [8]

Answer: m<6 = 68 degrees

Step-by-step explanation:

Angle 1 is supplementary to angle 4 because they are the product of two intersecting lines. This means angle 1 + angle 4 = 180 degrees. Subtract 112 from 180. 180-112 = 68. Angle 4 is 68 degrees.

The alternate interior angle theorem states that angles on the inside of the two parallel lines will be the same as the ones diagonal from them (4 = 6, 3 = 5 for this example). Since angle 4 is congruent to angle 6, angle 6 also measures 68 degrees.

In Leakwater township, there are two plumbers. On a particular day three Leakwater residents call village plumbers independently
Marianna [84]

Answer:

25% probability that all three residents will choose the same plumbe

Step-by-step explanation:

For each resident, there are only two possible outcomes. Either they choose the first plumbe, or they choose the second. The plumbers are chosen independent of each other. 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.

Each resident randomly chooses one of the two plumbers.

This means that p = \frac{1}{2} = 0.5

Three residents:

This means that n = 3

What is the probability that all three residents will choose the same plumb

This is P(X = 0)(all choose the second pumble) or P(X = 3)(all choose the first pumble). So

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

P(X = 0) = C_{3,0}.(0.5)^{0}.(0.5)^{3} = 0.125

P(X = 3) = C_{3,3}.(0.5)^{3}.(0.5)^{0} = 0.125

p = P(X = 0) + P(X = 3) = 2*0.125 = 0.25

25% probability that all three residents will choose the same plumbe
