Suppose that you are taking a T/F exam and you have no idea at all about the answers to the last three questions. You choose ans
podryga [215]

Answer:

0.375, 0.125, 0.5

Step-by-step explanation:

given that you are taking a T/F exam and you have no idea at all about the answers to the last three questions.

Probability for correct guess = 0.5 remains constant for each of the three questions

X - no of questions is binomial with n =3 and p = 0.5

1) the probability that you guessed right on exactly one of the three questions

= P(X=1)

= 3C1(0.5)^3 = 0.375

2) the probability that you guessed right on zero of the three questions

= P(X=0)\\= 0.5^3=0.125

3) the probability that you guessed right on at least two of the questions

=P(x=3)+P(2)\\= 1-0.5\\=0.5

Find the area of the figure.
Nady [450]

Answer:

Explanation:

So you want to start by finding the area of the big square.

We know the width to the big square is 60cm. The length to the big square is

=

56

Big square

A

r

a

=

L

⋅

W

=

56

⋅

60

=

3360

Now let’s find the little square inside the bigger square. We see from the picture that the width is 34 and the length is 24cm. Using the same formula, we can find the area of the little square.

Little square

A

r

=

816

The area enclosed is the area of the big square minus the area of the little square.

So the area enclosed is

A circular piece of fabric has a radius of 1.2ft. The fabric sells for $5.40 per ft2. What is the total cost of the circular pie
mixas84 [53]
Find the area of the fabric
The fabric is circular, so we find the area using the area of circle formula
a = π × r²

input the numbers
a = π × r²
a = 3.14 × (1.2)²
a = 3.14 × 1.44
a = 4.5216 ft²

Calculate the total cost
Multiply the cost by the area
cost = 5.4 × 4.5216
cost = 24.417
The total cost is approximately $24.42
