PEMDAS

We have to do multiplication before addition.

$7 \cdot 10 = 70\\70 \cdot 2 = 140\\\\140 + 5 = \boxed{145}$

145 is your answer. :)

A construction crew is lengthening a road. The road started with a length of 59 miles, and the crew is adding 2 miles to the roa

Illusion [34]

The answer is L = 59 + 2(d). If we plug in our numbers, we will get L = 59 + 2(32). 2*32 is 64, and if you add 59 you get 123 miles.

This isn’t apart of the question, but 59 would be the y-intercept. 2 miles per day (2/1) is the slope.

for events A and B, P(A)= 3/14 and P(B)= 1/5. Also, P(A and B)= 3/65. Are A and B independent events?

Lady_Fox [76]

No, A and B are not independent events

Step-by-step explanation:

Let us study the meaning independent probability

Two events are independent if the result of the second event is not affected by the result of the first event
If A and B are independent events, the probability of both events is the product of the probabilities of the both events P (A and B) = P(A) · P(B)

∵ P(A) = $\frac{3}{14}$
