Last month, Justina dog ate 50 cans of dog food in 30 days. How many cans should Justin buy for the next 6 days
natali 33 [55]

Answer:

The answer is 7 2/3 cans for the next 6 days.

Step-by-step explanation:

Given: The dog ate 50 cans in 30 days.

To get how many cans per day, divide:

50/30 = 1 2/3 cans per day.

To get how many cans for 6 days, multiply:

6 * 1 2/3 = 18/3 + 5/3 = 23/3 = 7 2/3 cans or 7.667 in decimal form.

Hope this helps!! Have an Awesome day!!! :-)

2. The route used by a certain motorist in commuting to work contains two intersections with traffic signals. The probability th
coldgirl [10]

Answer:

0.30

Step-by-step explanation:

Probability of stopping at first signal = 0.36 ;

P(stop 1) = P(x) = 0.36

Probability of stopping at second signal = 0.54;

P(stop 2) = P(y) = 0.54

Probability of stopping at atleast one of the two signals:

P(x U y) = 0.6

Stopping at both signals :

P(xny) = p(x) + p(y) - p(xUy)

P(xny) = 0.36 + 0.54 - 0.6

P(xny) = 0.3

Stopping at x but not y

P(x n y') = P(x) - P(xny) = 0.36 - 0.3 = 0.06

Stopping at y but not x

P(y n x') = P(y) - P(xny) = 0.54 - 0.3 = 0.24

Probability of stopping at exactly 1 signal :

P(x n y') or P(y n x') = 0.06 + 0.24 = 0.30
