The term that you want is 5C2*p^2*q^3 representing 2 successes and 3 failures. This term's value is

(5C2)(0.5^5) = 10*0.03125 = 0.3125 = P(2 successes in 5 trials) =31.3%

Evaluate each function following the specification.

telo118 [61]

Answer:

#3 a. g(-1) = 2, g(0) = 3, and g(1) = 2

b. No restrictions for all real numbers

$\#4 \ a. \ h(-1) = \dfrac{1}{3}, \ h(0) =0, \ h(2) = \infty$

b. Yes, x ≠ 2

Step-by-step explanation:

#3 The function is given as g(x) = -x² + 3

a. From the given function, by plugging in the value of 'x' in the bracket, we have;

g(-1) = -(-1)² + 3 = -1 + 3 = 2

g(-1) = 2

g(0) = -0² + 3 = 3

g(0) = 3

g(1) = -1² + 3 = -1 + 3 = 2

g(1) = 2

g(-1) = 2, g(0) = 3, and g(1) = 2

b. The given function g(x) = -x² + 3 for finding the value of g can take any value of x which is a real number

Therefore, therefore, there are no restrictions

#4 a. The given function is given as follows;

$h(x) = \dfrac{x}{x - 2}$

By substitution, we get;

$h(-1) = \dfrac{-1}{(-1) - 2} = \dfrac{-1}{-3} = \dfrac{1}{3}$

$\therefore h(-1) = \dfrac{1}{3}$

$h(0) = \dfrac{0}{0 - 2} = \dfrac{0}{-2} =0$

$\therefore h(0) =0$

$h(2) = \dfrac{2}{2 - 2} = \dfrac{2}{0} = \infty$

$\therefore h(2) = \infty$

$h(-1) = \dfrac{1}{3}, \ h(0) =0, \ h(2) = \infty$

b. From the values of the function, we have that h(x) is not defined at x = 2

Therefore, there is a restriction for x in the function, which is x ≠ 2

in a parade, each tricycle and bicycle have one rider.There are 64 wheels and 28 riders.How many tricycles are there? can you sh

Ann [662]

Answer:

8 tricycles

Step-by-step explanation:

Make a system of equations

Let t represent tricycles, and b represent bicycles

We know that tricycles have 3 wheels, bicycles have 2, and there are a total of 64 wheels

We also know each has one rider, and there are a total of 28 riders

3t+2b=64

t+b=28

Subtract t from both sides in the second equation. This will allow us to use substitution

b= -t+28

Substitute -t+28 in for b in the first equation

3t+2b=64

3t+2(-t+28)=64

Distribute the 2

3t + 2*-t+ 2* 28 =64

3t-2t+56=64

Combine like terms

t+56=64

Subtract 56 from both sides

t=8

There were 8 tricycles

A farmer is painting a new barn. He will need to calculate the surface area of the barn to purchase the correct amount of paint.

stira [4]

Answer:

ft^2

Step-by-step explanation:

Here in this question, we have a farmer who wants to purchase the correct amount of paint, but needs to know the surface area of the barn. We now need to select the correct unit in which the farmer would have his surface area.

In other words, what the question is simply asking us is to select which of the given units would serve as the appropriate unit for the surface area of the barn.

Mathematically, when we talk about area, we are simply talking about multiplying the length of a side with the length of another side.

We know the barn is not a single shape but shaped in terms of different segments which have different area and can be added together to give the total surface area of the barn.

Now, like we said above, we are multiplying a length by the length of another side, no matter the type of shape we are considering.

What this means is that our power( index) won’t be more than 2 since we can only multiply two sides of a particular length at a time.

So the option that would give the correct answer would be the option which has its power raised to the power of two.

The only option that fits the criterion is the last option which is the ft^2 and this in fact is the correct answer
