Answer:

∠ZVW= 45

∠ZWV = 31

x=1

Step-by-step explanation:

Properties of a Parallelogram ( including diagonals )

Diagonals of a parallelogram bisect each other.

The diagonals are cut into two equal parts

Opposite angles are congruent

Given this information we need to find x, ∠ZVW and ∠ ZWV

First lets find x

Like stated previously diagonals cut each other into two equal parts

That being said segment WZ ≅ segment ZY

Knowing this we create an equation

2z-1=1

step 1 add 1 to each side

-1 + 1 cancels out

1 + 1 = 2

now we have 2x = 2

step 2 divide each side by 2

2x/2=x

2/2=1

we're left with x = 1

Now lets find ∠ZVW

∠ZVW and ∠ZXY happen to be opposite angles ( opposite angles are congruent )

This means that because ∠ZXY = 45 ∠ZVW also = 45

Now lets find ∠ZWV

∠ZWV and ∠XYZ happen to be opposite angles ( like stated previously, opposite angles are congruent)

So because ∠XYZ = 31 ∠ZWV also = 31

S=100x^8y²z^6 is your answer

Step-by-step explanation:

we have

S=4πr²

when

r=5x⁴yz³

new S

will be

S=4π(5x⁴yz³)²=4×5²×x^(4×2)×y²×z^(3×2)

=100x^8y²z^6

Question Completion:

California (population about 40 million) has about twice as many people as New York State (population about 20 million). Without calculation, pick the correct option and explain your choice.

If the underlying population SDs are equal, a simple random sample of 1000 people in California is

(i) about half as accurate

(ii) about 1/V2 times as accurate

(iii) about as accurate

(iv) about V2 times as accurate

(v) about twice as accurate

as a simple random sample of 1000 people in New York State.

Answer:

If the underlying population SDs are equal, a simple random sample of 1000 people in California is

(i) about half as accurate

as a simple random sample of 1000 people in New York State.

Step-by-step explanation:

Since the population of California is about 40 million, which is twice as many people as in New York State (approximately 20 million), in taking a sample size, that of California supposed to be as twice as New York's.

Therefore, if the random sample of 1,000 people is taken from California, just as a random sample of 1,000 people is also taken from New York State, we can conclude that the accuracy of population standard deviation of California will be about half as accurate as the standard deviation of New York's population.

This is because accuracy is enhanced by a larger sample size.  This means that if the sample size of California is 2,000, the SD would have been equally as accurate as New York's.

Step-by-step explanation:

Given

d1 = 6 miles

d2 = 19 miles

d3 = ?

d1+d2+d3 = 50

6+19+d3 = 50

25+d3 = 50

d3 = 50 - 25

= 25miles

Answer:

The company bought 9 computers and 11 printers.

Step-by-step explanation:

Given that a company has to buy computers and printers, and each computer, x, costs $ 550 and each printer, y, costs $ 350, if the company spends $ 8,800 and buys a total of 20 machines, to determine how many of each did it buy the following calculation must be performed:

20 x 550 + 0 x 350 = 11,000

15 x 550 + 5 x 350 = 10,000

10 x 550 + 10 x 350 = 9,000

9 x 559 + 11 x 350 = 8,800

Thus, the company bought 9 computers and 11 printers.

I am currently working on the explanation.

Answer:

3 points

Step-by-step explanation:

A function is a relation that maps elements of a set for the inputs (the domain, usually denoted with the variable x) into elements of another set, the set of the outputs (the range, usually denoted with the variable y).

So the relation can be represented with points (x, y), which means that point x is being mapped into point y.

Such that the needed condition is that each element of the domain is mapped into only one element in the domain.

So for example, if for a relationship we have the points (a, b) and (a, c)

The point a is being mapped into two different outputs.

Now let's go to our problem, we have the points:

(-3, 2), (-3, 3), (1, 4), (1, -4), (2, -4), (2, -2)

If we have repeated inputs, we need to remove points until we have one of each.

We can see that the inputs -3, 1, and 2 are repeated one time.

Then we need to remove one of each, for example if we remove the second, fourth and sixth points, the set becomes:

(-3, 2), (1, 4), and (2, -4)

This is a function.

Then we need to remove 3 points.

C) 3 POINTS

Answer:

  12

Step-by-step explanation:

Let x be the smallest number, and y be the middle number. Then the largest number is 2x and the sum is ...

  x + y + 2x = 27   ⇒   y = 27 -3x

The requirement that the middle number is y gives rise to the inequality ...

  x < y < 2x

Substituting for y, we have ...

  x < 27 -3x < 2x

Adding 3x gives us ...

  4x < 27 < 5x

These two inequalities give us the requirement that ...

  27/5 < x < 27/4

  5.4 < x < 6.75

The only whole number in that range is x = 6. So, the greatest number is 2×6 = 12.

The greatest number is 12.

Step-by-step explanation:

AAS makes the most sense because you are only given information about 2 angles and a side, in that order

also the other answers don't work because vertical, alternate interior, and alternate exterior angles are only used as reasons when the angles are on parallel lines cut by a transversal, which is not the case here.

Answer: R47.66

Step-by-step explanation:

Assuming this amount of R42.42 is Indian Rupees, then the relevant VAT rate to use is 12.36% which is the VAT rate in India.

The VAT inclusive amount is therefore:

= 42.42 * ( 1 + tax rate)

= 42.42 * ( 1 + 12.36%)

= R47.66

Answer:

They are both 60 thats all I know im sorry.

Step-by-step explanation:

The answer is Option C - They both use same amount of paper!

Answer:

D or the last option

Step-by-step explanation:

For A: If we multiply 10 by 10 it gives us 100 and 8 by 10 is 80 and this off by 20 and we need to find number that are the closest.

For B: 16 by 10 is 160 and 16 by 8 is 128 and this has a big difference of 32. This also a big number and I don't know why a team would need 128 hotdogs.

For C: 40 by 10 is 400 and 8 by 40 is 320 and this wayyy of by 80. And i doubt a team needs 320 hotdogs.

For D: 4 by 10 is 40 and 8 by 4 is 32 this is only off by 8 and compared to the other options is the most closest and 32 hotdogs for a team should be reasonable.

Answer:53

Step-by-step explanation:

4240/80 = 53

53*80 = 4240

Answer:

53 yd

Step-by-step explanation:

Because you find the area of a field by multiplying the length by the width, this can be written as 4240=80x, where x equals the width of the field. Now all you have to do is divide 4240 by 80 to get what x, or the width, is.

HAVE A WONDERFUL DAY!!! please take care of yourself you deserve it :D

Step-by-step explanation:

HOPEFULLY THIS HELPS HERE: please read this so you can understand the problem too!!

so basically, first you are gonna find the triangle's perimeter. (reminder perimeter is add all sides) so 6+8= 14. then you are going to find the circumfrence of that circle using the formula 2πr and then divide by two since its HALF a circle. the radius is 5 (radius is half the diameter which would be 10) then put in your calculator 2π(5) and you should get 31.42. dont forget to divide by two since its half a circle. 31.42/2 =15.71. then add up your other lengths to that 14+15.71= 29.71(YOUR ANSWER :D)
