Answer:

Step-by-step explanation:

The line has points:

It has y-intercept b = -3 and a slope:

The equation:

It inverse is (let's call it g(x)):

The slope of the inverse function is 1/3 and the y-intercept is 1

The graph reflecting this is A

Answer:

[tex](xy)z = xyz[/tex]

Step-by-step explanation:

Given

[tex](xy)z[/tex]

Required

Equivalent expression

No option is given. So, I will solve generally.

To solve this question, we simply open the bracket.

So:

[tex](xy)z = xyz[/tex]

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.

Answer:

[tex]V=904.77\ cm^3[/tex]

Step-by-step explanation:

Given that,

The radius of sphere, r = 6 cm

We need to find the volume of the sphere.

The formula for the volume of a sphere is given by :

[tex]V=\dfrac{4}{3}\pi r^3\\\\=\dfrac{4}{3}\times \pi \times (6)^3\\\\=904.77\ cm^3[/tex]

So, the volume of the sphere is equal to [tex]904.77\ cm^3[/tex].

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.

Answer:

[tex]\angle ABC =60[/tex]

Step-by-step explanation:

Given

[tex]\angle CAB = 75[/tex]

The attached triangle

Required

Find [tex]\angle ABC[/tex]

First, calculate [tex]\angle BCA[/tex]

[tex]\angle BCA + 135 = 180[/tex] --- angle on a straight line

[tex]\angle BCA = 180 - 135[/tex]

[tex]\angle BCA = 45[/tex]

[tex]\angle ABC[/tex] is then calculated using:

[tex]\angle ABC + \angle BCA + \angle CAB =180[/tex] -- angle in a triangle

[tex]\angle ABC + 45+ 75=180[/tex]

[tex]\angle ABC =- 45- 75+180[/tex]

[tex]\angle ABC =60[/tex]

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:

∠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

Answer:

a. Given, Give, Given, AAS

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:

1. 16cm

2. 26dm

3. 20mm

4. 30dm

5. 78cm

Step-by-step explanation:

1. Perimeter of the square = 4cm + 4cm + 4cm + 4cm = 16cm

2. Perimeter = 8dm + 8dm + 5dm + 5dm

= 26dm

3. Perimeter of rectangle = 3mm + 3mm + 7mm + 7mm = 20mm

4. Perimeter of triangle = 8dm + 12dm + 10dm = 30dm

5. Perimeter = 23cm + 23cm + 16cm + 16cm = 78cm

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
