If Dante spins the spinner below 75 times, how many times should he expect it to land on "U"?

Fed [463]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete; So, I will solve making assumptions

$Spinner = 10\ segments$

$U = 1$

$n=75$

Required

Number of times to land on U

First, calculate the theoretical probability of U

$Pr(U) = \frac{U}{Spinner}$

$Pr(U) = \frac{1}{10}$

The expected number (E) of time to land on U is then calculated as:

$E = Pr(U) * n$

$E = \frac{1}{10} * 75$

$E = 0.10 * 75$

$E = 7.5$

Approximate

$E = 8$

8 times

Follow the above steps, and you will arrive at your answer

each blade on a windmill is in the shape of a triangle with a base of 7 feet and a height of 4 ft if there are four blades on th

Sunny_sXe [5.5K]

The total area of the blades is the area of a triangle multiplied by 4.

We have then:

$A = (4) * (1/2) * (b) * (h)$

Where,

b: base of the blades

h: height of the blades

Substituting values we have:

$A = (4) * (1/2) * (7) * (4)$

Doing the calculation we have that the area of the blades is given by:

$A = 56 feet ^ 2$

Answer:

The total area of the blades is:

$A = 56 feet ^ 2$
