Answer:

66.75m

Step-by-step explanation:

Area of Triangle: 4.5m

\frac{bh}{2}

height is 4.5m

base is 2m

overall height is 10m so 10-3.5-5= height of triangle

overall base is 10.75m so 10.75-3.25-2.5-3= base of triangle

Area of the smallest rectangle: 13.5m

base is 3m (provided)

height is 4.5m (same as triangle)

Area of the medium sized rectangle: 16.25m

base is 2.5m (provided)

height is 6.5

overall height is 10m so 10-3.5= the height of this rectangle

Area of largest rectangle: 32.5

base is 3.25m (provided)

heigh is 10m (provided)

Step-by-step explanation:

If the pepperoni is 26 1/2 inches long and he is cutting then 1/2 in slices. You are going to get 2 slices per inch. So multiply 26 x 2 which is 56 then add 1 for the half inch which gives you 57 slices

There is a 70% chance that your car will get stuck in the snow during the next big snow fall. Given that you are already stuck i
nikdorinn [45]

Answer:

63%

Step-by-step explanation:

This is a problem of conditional probability.

The two events that are given are:

  • Car stuck in the snow - Let it be event S. P(S) = 70% = 0.70
  • Require a tow truck - Let it be event T.

We have to find the probability of being stuck in the snow AND requiring a tow truck which can be given as P(S and T)

We are also given the conditional probability, which is P(T | S) = 90% = 0.90

Using the given formula for our case we can modify the formula as:

P(T|S)=\frac{P(S \cap T)}{P(S)}

0.90=\frac{P(S \cap T)}{0.70}\\\\ P(S \cap T)=0.90 \times 0.70\\\\ P(S \cap T)=0.63

Therefore, there is 63% (0.63) chance that you will get stuck in the snow with your car AND require a tow truck to pull you out
