For domain to work, we would need to find intersection of two domain sets. Because if one input causes one function to be undefined, then combined function would be undefined too.

So then domain of (u-v)(x) would be** the set of all real values except 0 and 2**.

Hope this helps.

So then domain of (u-v)(x) would be

Question

Suppose that a large number of samples are taken from a population. Which of the following sample sizes will be most likely to result in the sample proportion distribution having the largest standard deviation?

Solution 1

If you use a large enough statistical sample size, you can apply the Central Limit Theorem (CLT) to a sample proportion for categorical data to find its sampling distribution. The population proportion, p, is the proportion of individuals in the population who have a certain characteristic of interest (for example, the proportion of all Americans who are registered voters, or the proportion of all teenagers who own cellphones). The sample proportion, denoted

Question

Miriam makes 214 gallons of punch for a school event. How many 4‐ounce servings of punch can she serve ?

Solution 1

Convert gallons to ounces

There 128 ounces in 1 gallon

So you would multiply

(214gal)*(128oz/1gal)=27392 ounces

27392oz / 4 oz = 6848 cups

There 128 ounces in 1 gallon

So you would multiply

(214gal)*(128oz/1gal)=27392 ounces

27392oz / 4 oz = 6848 cups

Question

PLZ HURRRY!! Of the 12,000 votes cast in an election, 42% of the votes were for Mr.Jones. How many votes were cast for all the other candidates?

Solution 1

42/100 × 12000

= 5040

Therefore, Number of Voters left = 12000-5040

= 6960

= 5040

Therefore, Number of Voters left = 12000-5040

= 6960

Solution 2

6960 is the correct answer :)

Question

Iris is building a model of the Washington Monument. Her model measures 15 in. tall and is 1.5 in. wide at the base. The actual width measurement at the base of the Washington Monument is about 55 ft. About how tall is the Washington Monument?

Solution 1

**Answer: 550 **

** **

** **

**Step-by-step explanation:Solve the proportion: 15 in./1.5 in. = h/55 ft. The value of h is 550 ft. The Washington Monument is about 550 ft tall.**

Solution 2

Using how tall it is over how wide

=>tall/wide

The model 15in/1.5in

The actual x/55ft

Convert everything into the same units so 55ft to inches

There are 12in in 1ft

55ft * 12in/1ft

The ft cross out leaving in

55*12in= 660 in

So

15in/1.5in = x/660in

Now solve for x my multiplying both side by 660in

660in *15in/1.5in=x

x= 6600in tall

=>tall/wide

The model 15in/1.5in

The actual x/55ft

Convert everything into the same units so 55ft to inches

There are 12in in 1ft

55ft * 12in/1ft

The ft cross out leaving in

55*12in= 660 in

So

15in/1.5in = x/660in

Now solve for x my multiplying both side by 660in

660in *15in/1.5in=x

x= 6600in tall

Question

PLZ HELP NNOOOOOOOWW!! 15 points!! What is the midpoints of the line segment with endpoints (-3,7) and (9,-2)?

Solution 1

The midpoint of the line having the endpoints and is

basically average them

so given that the line has the endpoints of (-3,7) and (9,-2)

x₁=-3

y₁=7

x₂=9

y₂=-2

so the midpoint can be found by doing

the midpoint is

basically average them

so given that the line has the endpoints of (-3,7) and (9,-2)

x₁=-3

y₁=7

x₂=9

y₂=-2

so the midpoint can be found by doing

Question

What is the area of the given circle in terms of pi? Diameter 6.6. Please Help

Solution 1

Area=π*r^2

r=radius

2r=d -> d/2=r

we are given d, the diameter

we need r

so

d/2=6.6/2=3.3=r

therefore

area=π*r^2

area=π*(3.3)^2

area=π*10.89

area=10.89π square units

r=radius

2r=d -> d/2=r

we are given d, the diameter

we need r

so

d/2=6.6/2=3.3=r

therefore

area=π*r^2

area=π*(3.3)^2

area=π*10.89

area=10.89π square units

Solution 2

I believe the answer is 10.362

Question

A book club offers a choice of 8 books from a list of 40. In how many can a member make a collection?

Solution 1

You have to divide 40 by 8

40/8=5

40/8=5

Question

In the equation f(x) = (3x + 5) (x2 - 6x + 9)2 = 0, 3 has a multiplicity of ______.

Solution 1

Multiplicity is how many times the root (or zero) is repeated

example, in the root b has a multiplicity of n and the root d has a multiplicity of m

first we need to get the roots into

for (3x+5), we need to force factor out the 3 to get

factor the other one

but it is which is equivilent to which simplifies to

so we get

so the roots are -5/3 multiplicity 1 and 3 multiplicity 4

3 has a multilicity of 4

example, in the root b has a multiplicity of n and the root d has a multiplicity of m

first we need to get the roots into

for (3x+5), we need to force factor out the 3 to get

factor the other one

but it is which is equivilent to which simplifies to

so we get

so the roots are -5/3 multiplicity 1 and 3 multiplicity 4

3 has a multilicity of 4

Question

The Science Club went on a two-day field trip. The first day the members paid $30 for transportation plus $18 per ticket to the planetarium. The second day they paid $85 for transportation plus $15 per ticket to the geology museum. Write an expression to represent the total cost in dollars for two days for the n members of the club.

Solution 1

1st day $30+$18=$48

2nd day $85+$15=$100

You can do both days separate

$48n+$100n

Or add the days together and multiply the cost by the number of members

$148n

2nd day $85+$15=$100

You can do both days separate

$48n+$100n

Or add the days together and multiply the cost by the number of members

$148n
