First, multiply 7 to the numbers inside the parenthesis

So, 7*2 is 14 and 7*1 is 7

Then, your answer is (14+7)

Answer:

Step-by-step explanation:

Factory A proportion:

3 : 2,000

Factory B proportion:

5 : 4,500 (this can be simplified):

1 : 900

Now plug in 18,000 to each proportion:

Factory A:

x : 18,000

3 : 2,000

x = 27

Factory B:

x : 18,000

1 : 900

x = 20

Factory A had the greater amount of defects, 27

Given that a randomly chosen quadrilateral has four right angles, what is the probability that the quadrilateral also has four e

Alexxx [7]

Answer:

0.25

Step-by-step explanation:

This is the question on conditional probability

Let A - the quadrilateral has four right angles

B - the quadrilateral has four equal side lengths

Required probability = P(B/A)

By definition of continuous probability

$P(B/A) = \frac{P(AB)}{P(A)}$

$P(AB) = \frac{2}{20} =0.10$

P(A) = $\frac{8}{20} =0.4$

Hence given probability = $\frac{0.1}{0.4} =0.25$

liberstina [14]

Answer:

Step-by-step explanation:

"12 more than the quiotent of a number n of and two decreased by 4"

$\left(\dfrac{n}{2}-4\right)+12$

Simplify:

$\left(\dfrac{n}{2}-4\right)+12=\dfrac{n}{2}-4+12=\dfrac{n}{2}+8$

Put n = 4 to the expresssion:

$\dfrac{4}{2}+8=2+8=10$
