The number of 2 person subcommittees that can be chosen from a 10 person committee.

The number of 2 person teams that can be picked form 10 people.

Answer:

When there is the no of ways where the president and the vice president should be selected from the grouping of 10 people does not represent the combination.

The following information should be considered:

- In the case when the people are picked out for particular role so here the order should be matter. It should be the situation of permutation, not the combination situation.
- Based on this, the last 2 options are considered to be the combination

Therefore we can conclude that when there is the no of ways where the president and the vice president should be selected from the grouping of 10 people does not represent the combination.

Answer: The answer is the number of ways a President and Vice President can be chosen from a group of 10 people.

When you're picking people for specific roles, the order in which people are picked matters. That is a permutations situation, not combinations.

For the others, they're situations that can be modeled with combinations since order does not matter. All that matters when you make a subcommittee or a duo-team is who's in it.

Andre said, I found two figures that are congruent, so they can’t be similar.” Diego said, No, they are similar! The scale factor is 1.”who is correct use the definition of similarity to explain your answer

Congruent Figures are defined as figures that are identical in size and shape. Or simply when one figure is the mirror image of the other, the figures are said to be congruent. The angles, lengths of sides, overall dimensions of congruent figures are identical.

Similar Figures are figures having same shape. Although such figures may differ in their sizes.

All congruent figures are similar, but not all similar figures are congruent.

Therefore, Diego's point regarding congruent and similar figures is correct. Congruent figures are necessarily of same shape and size but similar figures may have different sizes.

Jacqueline reads 25 pages every night. Which graph correctly displays y, the total number of pages that Jacqueline has read after x days?

The correct answer is) D. Because on the graph you can see that it increases by 25 each day which follows the equation Y=25x

The reason for this is because she reads 25 pages a night Meaning that the total number of pages Jacqueline has read (Variable Y) = 25 pages a night (x)

y = 25x

In case of 3 days y = 25x3=75 pages

4 days y =25x4=100 pages

Without multiplying or estimating explain how you can tell which product is greater 4.5 times 7.32 or 0.45 times 732.

0.45 times 732 because 732 is the largest whole number and 0.45 is above zero so it wouldn’t still be bigger than 4.5 times 7.32

How would 1 1/3 be the answer of 12/9? Show work please.

Answer:

Kinda a whack question but I'll try.

Step-by-step explanation:

1 1/3 is a mixed number, to turn a mixed number into an improper fraction you need to first multiply the denominator to the whole number (3x1) and that's 3

next you add that number (3) to the numerator (1) so 3+1 and the denominator stays the same as it was (3)

and you are left with 4/3, multiply that by 3/3 (3) and you are left with 12/9

1 1/3 =12/9

The wording on your question is a little rough, but I think I got you an answer.

Answer:

Did you try simplifying as a decimal then turning it back to a fraction?

What is the monthly payment for $280000 mortgage with an interest of 6% compounded monthly for 20 years?

The formula of the present value of an annuity ordinary is

Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]

Pv present value 280000

PMT monthly payment?

R interest rate 0.06

K compounded monthly 12

N time 20 years

Solve the formula for PMT

PMT=pv÷[(1-(1+r/k)^(-kn))÷(r/k)]

PMT=280,000÷((1−(1+0.06÷12)^(

−12×20))÷(0.06÷12))

=2,006.01

Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]

Pv present value 280000

PMT monthly payment?

R interest rate 0.06

K compounded monthly 12

N time 20 years

Solve the formula for PMT

PMT=pv÷[(1-(1+r/k)^(-kn))÷(r/k)]

PMT=280,000÷((1−(1+0.06÷12)^(

−12×20))÷(0.06÷12))

=2,006.01

Determine the domain of the function. f(x) = sqrt(x 3)/(x 8)(x - 2)

All real numbers except –8, –3, and 2

x ≥ 0

All real numbers

x ≥ –3, x ≠ 2 <-- this one

i.e. x ≥ –3, x ≠ 2

Is y=4x-1 and 12x=3y+7 parallel, perpendicular, or neither

Answer:

Neither is the answer.

Step-by-step explanation:

If a line y = m₁x + c₁ and y = m₂x + c₂ are perpendicular to each other then m₁ × m₂ = -1

If both the lines are parallel to each other then m₁ = m₂

Now two lines have been given as

y = 4x - 1 ----------(1)

12x = 3y + 7

3y = -12x + 7

y = -4x + ------(2)

Now from equation (1) and equation (2),

m₁ = 4 and m₂ = -4

Since m₁ ≠ m₂

Therefore, these lines are not parallel

m₁ × m₂ = 4 × (-4) = -16

Therefore, both the lines are neither parallel nor perpendicular.

First, you simplify 12x=3y+7. Subrtact 7 from both side, get 12x-7=3y. Divide 3 from both sides, get y=4x-(7/3). Your 2 equations are y=4x-1 and y=4x-7/3. The 2 lines are parallel, since they have the same slope but different b's.
