pls show work?!!!!!!!

Answer:

As shown in picture,

perimeter of inside pentagon: p1 = n + n + n + n + n = 5n

ratio between inside pentagon and outside pentagon: r = 6/(6 + 6) = 1/2

=> perimeter of outside pentagon: p2 = 2 x p1 = 2 x 5n = 10n

=> Option B is correct

Hope this helps!

Answer:

  neither exponential nor linear

Step-by-step explanation:

A linear relationship will show a common difference between adjacent value. Here, the first differences between the first three values are 5 and 33. They are not the same, so the relation is not linear.

__

An exponential relationship will show first differences that are continuously increasing or decreasing by increasing or decreasing amounts (respectively).

As we showed, the difference between May 28 and May 27 is 33. This is more than the previous difference. However, the difference between May 30 and May 31 is only 28, which is less than a previous difference.

The relation is not exponential.

__

A graph points up the non-linearity of the relation.

0.36|6=0.366

The solution is : The given statement is False.

A histogram is an approximate representation of the distribution of numerical data. A histogram is a graph that shows the frequency of numerical data using rectangles. The height of a rectangle (the vertical axis) represents the distribution frequency of a variable (the amount, or how often that variable appears).

here, we have,

We are given a  the 30 data points which represent the best lifetime baseball batting averages of all time, arranged in order from lowest to highest.

As we know that we could obtain a frequency table from the following set of data points and histogram is a good way to represent the frequency data. ( i.e. a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins ).

Hence, the given statement,

A frequency table for these data can best be graphically displayed as a bar graph. That is, it should not be displayed as a histogram is a FALSE STATEMENT.

Answer:

1. The rocket was launched from a height of 180 feet.

=> Valid because at time = 0 sec, height = 180 feet (as shown in table)

2.The maximum height of the rocket occurred 3 seconds after launch.

=> Valid because at time = 3 sec, height = 324 feet (greatest value in second row of table).

3.The rocket was in the air approximately 6 sec before hitting ground.

=> Not valid because the time in table in about 7 sec (from 0 to 7), but all of the heights are greater than 0 (the rocket has not hit the ground yet).

4. The rocket was above 300 feet for approximately 2 seconds.

=> Valid because from sec 2 to sec 4: the height is greater than 300 (308, 324, and 308)

=> Option 3 is not valid.

Answer:

The margin of error is multiplied by 1.41, which is 1 divided by the square root of 5.

Step-by-step explanation:

The margin of error is:

[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]

In which z is related to the confidence level, [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

The margin of error is inverse proportional to the square root of the sample size.

Then

Sample size n:

[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]

Modified(half the sample size):

[tex]M_{M} = z*\frac{\sigma}{\sqrt{0.5n}}[/tex]

Ratio

[tex]\frac{M_{M}}{M} = \frac{z*\frac{\sigma}{\sqrt{0.5n}}}{z*\frac{\sigma}{\sqrt{n}}} = \frac{\sqrt{n}}{\sqrt{0.5n}} = \frac{\sqrt{n}}{\sqrt{0.5}*\sqrt{n}} = \frac{1}{\sqrt{0.5}} = 1.41[/tex]

The margin of error is multiplied by 1.41, which is 1 divided by the square root of 5.

Answer:

A = $ 7,299.92

A = P + I where

P (principal) = $ 6,000.00

I (interest) = $ 1,299.92

Step-by-step explanation:

A = P(1 + r/n)^nt

Where:

A = Accrued Amount (principal + interest)

P = Principal Amount

I = Interest Amount

R = Annual Nominal Interest Rate in percent

r = Annual Nominal Interest Rate as a decimal

r = R/100

t = Time Involved in years, 0.5 years is calculated as 6 months, etc.

n = number of compounding periods per unit t; at the END of each period

Answer:

5,004,300

Step-by-step explanation:

Answer:

Mean, E(x) = 0.17

Variance, V(x) = 0.12

Step-by-step explanation:

90% contains no defective bulbs, P(X=0) = 0.9

5% contain one defective bulbs, P(X=1) = 0.05

3% contain two defective bulbs, P(X=2) = 0.03

2% contain three defective bulbs, P(X=3) = 0.02

The mean for the number of defective bulbs:

[tex]E(X) = \sum XP(X)\\E(X) = (0*0.9) + (1*0.05) + (2*0.03) + (3* 0.02)\\E(X) = 0 + 0.05 + 0.06 + 0.06\\E(X) = 0.17[/tex]

Variance for the defective bulbs:

[tex]V(x) = (\sum x^{2}P(x) ) - \mu^2[/tex]

[tex]\sum x^{2}P(x) = (0^2*0.9) + (1^2*0.05) + (2^2*0.03) + (3^2* 0.02)\\\sum x^{2}P(x) = 0.05 + 0.12 + 0.12\\\sum x^{2}P(x) = 0.29[/tex]

V(x) = 0.29 - 0.17

V(x) = 0.12

Answer:

A) 180 packets

B) €450

Step-by-step explanation:

A) There are 300 packets of 1 kg of sugar in a container.

3/5 of the total amount is:

3 / 5 * 300 = 180 packets

B) Each packet goes for €2.50.

3/5 of the total amount is 180 packets, therefore, 180 packets will go for:

2.5 * 180 = €450

Answer:

0.011 or 1/90

Step-by-step explanation:

Since the order of the performances is determined at random the probability of each squad is constant that 1/10

The probability of your squad is 1/10

Given that the first selected was yours (1/10) nine squads are left . Therefore the probability of your friends squad is 1/9.

Hence  the probability that your squad performs first and your friend's squad performs second is (1/10 * 1/9) 1/90 or 0.011

Pytagora's Theorem

Step-by-step explanation

a = 4 m

b = 15 m

c = ?

a^2 + b^2 = c^2

√ a^2 + b^2 = c

a^2 = 16 m

b^2 = 225 m

√  16 + 225 = c

√  241 = 15.52 m

c = 15.52 m

Answer:

0.85% probability that the first two are good and the last three are spoiled

Step-by-step explanation:

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

The order in which the first two jugs is not important, as is not the order in which the last three are selected. So we use the combinations formula to solve this question.

Combinations formula:

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

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

Desired outcomes:

2 spoiled, from a set of 43-11 = 32.

3 spoiled, from a set of 11.

So

[tex]D = C_{32,2}*C_{11,3} = \frac{32!}{2!(32-2)!}*\frac{11!}{3!(11-3)!} = 982080[/tex]

Total outcomes:

5 jugs from a set of 43.

[tex]T = C_{43,5} = \frac{43!}{5!(43-5)!} = 115511760[/tex]

Probability:

[tex]p = \frac{D}{T} = \frac{982080}{115511760} = 0.0085[/tex]

0.85% probability that the first two are good and the last three are spoiled

Answer:

12 square units.

Step-by-step explanation:

We must find the area of each shape and add together. The area of a triangle is 1/2 base times height. The smaller triangles area is 2 and the larger triangle's area is 6. The area of the square is 4... so when all added together, we have 12.
