The length and the width of a rectangle are in the ratio of 5 to 2, and the area is 1,000 sq. ft. Find the dimensions.
sleet_krkn [62]

Step-by-step explanation:

l = length

w = width

l/w = 5/2

l = 5w/2

l×w = 1000ft²

(5w/2)×w = 1000

5w²/2 = 1000

5w² = 2000

w² = 400

w = 20ft

l = 5w/2 = 5×20/2 = 5×10 = 50ft

the length is 50ft.

the width is 20ft.

A total of 8 representatives need to be chosen from a group of 40 students, of which 24 are female and 16 are male. In how many
Diano4ka-milaya [45]

Answer:

Probability = 0.0147

Step-by-step explanation:

To find this, we need to know the number of ways the representatives can be picked overall, and then the number of ways 3 females and 3 males can be the representatives. The fraction of the two will be the probability.

The total number of ways the representatives can be picked is the combination of a pool of 40 students and choosing 8 is; C(40,8) = 40!/((8!)(40 - 12)!)

= 76904685

We have gotten the number of ways the representatives can be picked.

Now let's find how many ways can the jury consist of 3 females and 3 males

For the males, there are 16 in the pool and we're picking 3:

Thus, C(16,3) = 16!/((3!)(16 - 3)!) = 560

For the females, there are 24 in the pool and we're picking 3:

Thus, C(24,3) = 24!/((3!)(24 - 3)!) = 2024

Thus, number of men and women choices = 2024 x 560 = 1133440

So; probability = 1133440/76904685 = 0.0147

One of the tallest living men has a height of 236 cm. One of the tallest living women is 224 cm tall. Heights of men have a mean
Roman55 [17]

Answer:

A. The woman is relatively taller because the z score for her height is greater than the z score for the man​'s height.

Step-by-step explanation:

Whoever has the highest z-score, is taller relative to the population of the same gender.

The z-score of a value X in a set with mean \mu and standard deviation /sigma is given by:

Z = \frac{X - \mu}{\sigma}

Solution:

Heights of men have a mean of 170 cm and a standard deviation of 6 cm. One of the tallest living men has a height of 236 cm. So the z-score of his height is:

Z = \frac{X - \mu}{\sigma} = \frac{236-170}{6} = 11

Heights of women have a mean of 161 cm and a standard deviation of 5 cm.

One of the tallest living women is 224 cm tall. The z-score of the women's height is

Z = \frac{X - \mu}{\sigma} = \frac{224-161}{5} = 12.6

The women has a higher z-score, so she is relatively taller.

The correct answer is A
