Josh wants to put a fence around his rectangular garden. The garden is 6 feet bt 15 feet. How much fencing must he purshase ?

1 answer:

6 0

Since the garden is a rectangle, there are 2 sides that are 6-ft long
and two sides that are 15-ft long.

So he needs (2 x 6) + (2 x 15) = (12) + (30) = 42-ft of fence. Minimum.

A right cone has a radius of 13 cm and a slant height of 20 cm. Find its surface area.

devlian [24]

Answer:

$A=1347.7\ cm^2$

Step-by-step explanation:

Given that,

Radius of a cone, r = 13 cm

Slant height of the cone, l = 20 cm

We need to find the surface area of the cone. The formula for the surface area of the cone is given by :

$A=\pi rl +\pi r^2$

Put all the values,

$A=\pi r(l + r)\\\\A=\pi \times 13(20 + 13)\\\\A=1347.7\ cm^2$

So, the surface area of the cone is $1347.7\ cm^2$ .

How do you solve-

gtnhenbr [62]

If 75% of the students had taken 8 courses, 25% had not. Of these remaining 25%, 60% of them (or 60% of 25% = 15%) had taken 6 or 7 courses. Thus 90% (75% + 15%) of the students had taken 6, 7 or 8 courses.

Thus only 10% had taken less than 6 courses. I hope this helps.

Jury Duty Three people are randomly selected from voter registration and driving records to report for jury duty. The gender of

Georgia [21]

Answer:

(a) The experiment defined here is a random variable that includes the selecting of 3 people from the set of voter registration and driving records.

(b) The simple events in sample space, S = (M, M, M), (M, F, M), (M, M, F), (F, M, M), (F, M, F), (F, F, M), (M, F, F), and (F, F, F).

(c) If each person is just as likely to be a man as a woman, then the probability for each of the simple event can be assigned as $0.5 \times 0.5 \times 0.5 = 0.125$ .

(d) The probability that only one of the three is a man is 0.375.

(e) The probability that all three are women is 0.125.

Step-by-step explanation:

We are given that three people are randomly selected from voter registration and driving records to report for jury duty. The gender of each person is noted by the county clerk.

(a) The experiment defined here is a random variable that includes the selecting of 3 people from the set of voter registration and driving records.

(b) As we know that the gender of each person is noted by the county clerk, which means one is male and another female.

So, the simple events in sample space, S = (M, M, M), (M, F, M), (M, M, F), (F, M, M), (F, M, F), (F, F, M), (M, F, F), and (F, F, F).

Here, M is denoted for male and F for female.

(c) If each person is just as likely to be a man as a woman, then the probability for each of the simple event can be assigned as $0.5 \times 0.5 \times 0.5 = 0.125$ .

Because there is 50-50 chance of selecting males or females.

(d) The probability that only one of the three is a man is given by;

The total cases in the sample space = 8

Number of cases of only one man out of three = 3

So, the required probability = $\frac{3}{8}$ = 0.375.

(e) The probability that all three are women is given by;

The total cases in the sample space = 8

Number of cases of all three are women = 1

So, the required probability = $\frac{1}{8}$ = 0.125.
