grigory [225]

Answer:

Doug sold 100 sandwiches in his neighborhood.

Step-by-step explanation:

To solve for percentage you have to first find the percentage's decimal. To find this you have to the move the decimal point up to places. This makes 80 into 0.8. After you do this you will mutiply that but the total amount. So 125 times 0.8. Once you do this you should get 100. This means that Doug sold 100 sandwiches in his neighborhood.

Which question represents the line through (0,0) and (2,5)?
madam [21]

Answer:

y=5/2x

Step-by-step explanation:

The line needs to go through the points (0,0) and (2,5).

With y=5/2x, there is no y-intercept, so it starts on the origin, (0,0). With the slope 5/2, you would rise 5 (y) from the origin, and run 2 (x), which gives you the point (2,5).

lapo4ka [179]

Answer:

A and B are independent events if P(A ∩ B) = 0.06

Step-by-step explanation:

Two events A and B are independent if the probability of occurrence of A does not influence the occurrence of B.

Mathematically it is written that A and B are independent events if and only if:

P(A ∩ B) = P(A)P(B)

We know that:

P(A) = 0.20

P(B) = 0.30

Then A and B are independent if:

P(A ∩ B) = (0.20)(0.30)

P(A ∩ B) = 0.06

Finally A and B are independent events if P(A ∩ B) = 0.06
