Answer:
A) 50
B) 20
C) 20
Step-by-step explanation:
To solve the first question, we can multiply both sides by 10.
Thus, we get:
6x = 300.
Then, divide by 6, to get x:
x = 50.
You can do the same thing to all of these questions.
I've already checked the answers, but if you don't trust them, just pluck the values in.
For example, let's check the answer for question A.
0.6*50 is supposed to equal 30.
Does it equal? Yes, so we know that the answer is correct.
<span>The computation for the confidence level = (18/20) x 100% =
90 %, the E or the margin error = 0.023 and the p = to 0.71. Confidence
interval can be achieved by using the formula (p-E, p+E) = (0.71-0.025,
0.71+0.025). Therefore, the confidence interval is (0.685,0.735).</span>
Answer:
There are 15 combinations.
Step-by-step explanation:
A restaurant is offering a dinner special that includes one starter and one entree.
Starter: bread-sticks, soup, salad
Entree: beef, fish, chicken, shrimp, pork
So, we have 3 starters and 5 entrees.
To know the possible dinner special combinations we will simply multiply the two.

Therefore, there are 15 combinations.

16/24 and divide the greatest common factor (8)
