2 answers:

4 0

70% of 200 is 140. 1/4 of 160 is 40. so 70% of 200 is bigger.

Hope this answer helps! feel free to ask any additional questions :)

Also if you are good at Geometry, would you mind seeing if you can answer some of the questions on my profile?

Answer:

-8,-40,-200,-1000,-5000,-25000

Step-by-step explanation:

a1 = -8

Let n = 2

a2 = 5 a1 = 5*(-8) = -40

Let n =3

a3 = 5 * a2 = 5 * -40 = -200

Let n =4

a4 = 5 * a3 = 5 * -200 = -1000

Let n =5

a5 = 5 * a4 = 5 * -1000 = -5000

Let n =6

a6 = 5 * a5 = 5 * -5000 = -25000

If we inspect photocopy paper by randomly drawing 5 sheets without replacement from every pack of 500, what is the probability o

earnstyle [38]

Answer:

98.01% probability of getting 5 clean sheets

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem, the order that the sheets are chosen is not important, so we use the combinations formula to solve this problem.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

0.4% of the sheets contain spots

Of 500, that is 0.004*500 = 2.

What is the probability of getting 5 clean sheets although 0.4% of the sheets contain spots?

Desired outcomes

2 are defective, so 5 sheets from a set of 500 - 2 = 498.

$D = C_{498,5} = \frac{498!}{5!493!} = 250160254344$

Total outcomes

5 sheets from a set of 500.

$T = C_{500,5} = \frac{500!}{5!495!} = 255244687600$

Probability:

$P = \frac{D}{T} = \frac{250160254344}{255244687600} = 0.9801$

98.01% probability of getting 5 clean sheets

The heights of 1000 students at a local school were recorded and found to be approximated by the normal curve below. Which answe

Vlada [557]

Answer:

The mean of the distribution of heights of students at a local school is 63 inches and the standard deviation is 4 inches.

Step-by-step explanation:

The normal curve approximating the distribution of the heights of 1000 students at a local school is shown below.

For a normal curve, the mean, median and mode are the same and represents the center of the distribution.

The center of the normal curve below is at the height 63 inches.

Thus, the mean of the distribution of heights of students at a local school is 63 inches.

The standard deviation represents the spread or dispersion of the data.

From the normal curve it can be seen that values are equally distributed, i.e. the difference between two values is of 4 inches.

So, the standard deviation is 4 inches.

a cylinder has a height of 12 feet and a radius of 14 feet. what is its volume? use ≈ 3.14 and round to the nearest hundredth

Komok [63]

Answer:

V = 7385.28

Step-by-step explanation:

Formula of the volume of a cylinder: V = pi*r^2*h

Since you are told to replace pi with 3.14, now plug in the numbers that you are given into the formula...

V = (3.14)(14)^2*(12)

= 7385.28

Notes: Remember you always have to divide your radius in half if it gives you a diameter, BUT since in this question it's given, you don't have to do any extra work :)
