Answer:

The true statements are the third and fifth. [not sure about the second one!]

Step-by-step explanation:

1.) (7u + 4) is written as a sum of three terms.

This is false since 7u is one term, and 4  is one term, making a total of two terms, not three.

2.) 2 is a factor

I'm not sure on this but I don't think its true.

3.) In 7u, 7  is a coefficent

This is true. The coefficent is the number in front of a variable, or in this case, 7.

4.) In (7u + 4), 7u is a constant.

This is false, as a constant is a number without  any variable attached to it. The constant in this case would be 4.

5.) 8 and 1 are like terms.

This is true, since you can add 8 and 1, resulting in the sum of 9.

6.) None of these are true.

This is false, as at least 2 of these statements are true.

I hope this helps! :)

Final answer:

The probability that Nick oversleeps and has a pop quiz on the same school day, given the probability of oversleeping at 48% and pop quiz at 25%, is 12%.

Explanation:

To find the probability that Nick oversleeps and has a pop quiz on the same day, we need to multiply the probabilities of the two independent events occurring.

The probability of Nick oversleeping is 48% or 0.48, and the probability of him having a pop quiz is 25% or 0.25. Since the events are independent, the combined probability is:

Probability(Nick oversleeps and has a pop quiz) = Probability(Nick oversleeps) × Probability(has a pop quiz) = 0.48 × 0.25

When you calculate this, you get:

0.48 × 0.25 = 0.12

Therefore, the probability that Nick oversleeps and has a pop quiz on the same school day is 12%.

The probability that Nick oversleeps and has a pop quiz on the same day is 12%.

To find the probability that Nick both oversleeps and has a pop quiz on the same day, we use the concept of independent events in probability. When two events are independent, the probability of both events occurring is the product of their individual probabilities.

Let's denote:
P(O) = Probability that Nick oversleeps = 0.48
P(Q) = Probability that there is a pop quiz = 0.25

The formula for finding the probability of both independent events occurring is:
P(O and Q) = P(O) * P(Q)

Therefore:
P(O and Q) = 0.48 * 0.25 = 0.12

So, the probability that Nick oversleeps and has a pop quiz on the same day is 12%.

Answer:

y = -1/3x +3

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/(x2-x1)

   = (2-3)/(3-0)

   -1/3

Then we know the y intercept( where it crosses the y axis)

It crosses at y=3

The slope intercept form is

y= mx+b  where m is the slope and b is the y intercept

y = -1/3x +3

Answer:

[tex]y=\frac{-1}{3} x+3[/tex]

Step-by-step explanation:

Let frame the equation of the line using the points given on the graph

(0,3) and (3,2)

Equation of the line is y=mx+b

where m is the slope and b is the y intercept

To find slope we use formula

[tex]slope =\frac{y_2-y_1}{x_2-x_1} =\frac{2-3}{3-0} =\frac{-1}{3}[/tex]

Y intercept b is the point where the graph crosses y axis

y intercept b = 3

The equation y=mx+b becomes

[tex]y=\frac{-1}{3} x+3[/tex]

Answer:

(f-g)(x) = 2√x - 2x³

Step-by-step explanation:

Write out the terms of f(x) as they are and then the negatives of all the terms of g.  We get:

(f-g)(x) = √x - x - 2x³ + √x + x

Combining like terms, we get:

(f-g)(x) = 2√x - 2x³

Answer:

x = 1, y = 60

Step-by-step explanation:

Value of new-releases (x) = $20 each

Value of classic (y) = $8 each

Total budget = $500

Equation : 20x + 8y = 500

The librarian wants to purchase maximum DVDs. She can get more DVDs of classic movies for $8 as they are less costly.

Lets assume the librarian buys at least one new-release DVD.

x=1

20x + 8y = 500

8y + 20(1) = 500

y = 60

Therefore, in a budget of $500, the librarian can purchase 60 classic movies and 1 new-release.

The vertex of this function is (3,8)

This function opens downwards so its range is

The function

[tex]g(x) = - \sqrt{x + 3} + 8[/tex]

Answer:

A

Step-by-step explanation:

Nice problem.

The only way you can get an odd number by multiplying two digits together is if they are both odd.

For example 5*7 = 35 which is odd. You cannot find 2 odd numbers that when multiplied will give an even.

That means that A and B are both odd.

Now if you multiply an odd and an even together, you always get an even.

For example 4 * 9 = 36 which is even.

Since A is known to be odd, C must be even. So the four digit number you want ends in C.

The Answer is A

Answer:

Step-by-step explanation:

The option that describes the Complement A^c is; D: A^c = {x| x ∈ U and x is an even positive integer}

If the Universal set, U = {all positive integers); and

A = {x|x ∈ U and x is an odd positive integer}.

Thus:

The complement of A is the set of the elements of the universal set which are not in A.

If a set is not odd, then it is even.

Thus:

A^c = {x| x ∈ U and x is an even positive integer}

Answer:

Ball Bearing Volume = (4 / 3) * PI * radius ^3

Volume = (4 / 3) * 3.14159265 * (.35)^3

Volume = (4 / 3) * 3.14159265 * 0.042875

Volume = 0.17959438 cc

1 cc of steel = 7.8 g

Volume of 1 kg of steel = 1,000 cc / 7.8 g per cc

1 kg = 128.205 cc

Number of ball bearings we can make = 128.205 / 0.17959438

Hi my name is Kylie "How You Doing" phrase from Friends, Joey

Answer:

  $293.75

Step-by-step explanation:

Any number of financial calculators, spreadsheets, and on-line calculators can compute the monthly payment for you. Or you can put the numbers into the formula and compute it yourself.

A formula I like is ...

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

where A is the monthly payment, P is the loan amount, r is the annual interest rate, and t is the number of years. Filling in the given information and doing the arithmetic, we get ...

  A = $10000(0.18/12)/(1 -(1 +0.18/12)^(-12·4)) = $150/(1 -1.015^-48) = $293.75

Your monthly payment is $293.75.

Here, the interval is [3, 11].  f(3) = -4 and f(11) = 20.

(f(11) − f(3)) / (11 − 3)

(20 − -4) / 8

24 / 8

The average rate of change in t over the interval [3,11] is C. 3.

The average rate of change function exists expressed as the average rate at which one quantity is changing regarding something else changing. In simple terms, an average rate of change function exists as a process that estimates the amount of change in one item divided by the corresponding amount of change in another.

The average rate of change of a function f(x) on the interval [a, b] is:

(f(b) − f(a)) / (b − a)

Here, the interval is [3, 11].  f(3) = -4 and f(11) = 20.

(f(11) − f(3)) / (11 − 3)

(20 − -4) / 8

Answer:

b ≠ - 1

Step-by-step explanation:

The denominator of the rational expression cannot be zero as this would make it undefined.

Equating the denominator to zero and solving gives the value that b cannot be.

solve

5b + 5 = 0 ( subtract 5 from both sides )

5b = - 5 ( divide both sides by 5 )

b = - 1 ← excluded value
