hill. The altitude, h, in feet, of the balloon x hours after starting its ascent from the
hill, can be modeled by the function: h(x) = -16x2 + 64x + 80.

Answers

Answer:

Step-by-step explanation:

p + n + d + q = 25

Put everything into quarters.

p and q are equally likely to be drawn

q + n + d + q = 25

There are 3 times as many nickels as quarters

n = 3q

q + 3q + d + q = 25

There is 25% more dimes than quarters.

d = 1.25 q

q + 3q + 1.25q + q = 25

6.25 q = 25

q = 25/6,25

=====================

q = 4

p = 4

d = 1.25 * 4 = 5

n = 12

Find two numbers the quotient between. Then estimate the quotient. 41÷3

Answers

Answer:

The quotient is between 10 and 15, and the exact answer is 13 with the remainder of 2: 13R2.

Step-by-step explanation:

41 ÷ 3 is a very long answer so do 39 ÷ 3 which equals 13 and since you can't divide 2 by three without negatives, just do it as a remainder of 2, or R2, which means the answer is 13 with the remainder of 2, or just 13R2.

Answer:  The outdoor temperature is 4 degrees below 0 or -4 degrees.

The indoor temperature is 72 degrees above 0 or 72 degrees.

Step-by-step explanation:

We use negative integer to represent loss, below , or withdrawal etc.

On the other hand we use positive integers to show gain , above , deposit etc.

Given statement :   The outdoor temperature is 4 degrees below 0.

So we will represent it by -4 degrees.

The indoor temperature is 72 degrees above 0.

So we will represent it by +72 or 72 degrees.

Answers

Answer:

-12 + 20x ≥ -6x + 9

Fourth choice

Step-by-step explanation:

Inequalities

We are given the inequality:

-4(3 - 5x) ≥ -6x + 9

Solving the inequality implies having x isolated on one of the sides.

We must start by removing the parentheses. It will be done by multiplying -4 by (3 - 5x). Since this operation doesn't imply multiplying all the inequality by a negative number, the sign won't be flipped:

-4*3 - (-4)5x ≥ -6x + 9

Multiplying:

-12 + 20x ≥ -6x + 9

You typically buy all of your groceries at Grocery Mart. This week, your favorite cereal is on sale there, 4 boxes for $10. At Food Market, where you don’t typically shop, the same cereal is on sale for $2.25 a box.

Answers

Answer:

B. Food market

Step-by-step explanation:

You typically buy all of your groceries at Grocery Mart. This week, your favorite cereal is on sale there, 4 boxes for $10. At Food Market, where you don’t typically shop, the same cereal is on sale for $2.25 a box. Based on price, which is the better value option?

A.Grocery Mart

B. Food Market

Grocery market:

4 boxes for $10

Unit price = cost / quantity

= $10 / 4 boxes

= $2.50 per box

Food market:

Price per box = $2.25

The better value option based on price is food market because it cost less to buy a box of cereal than grocery mart

Of all airline flight requests received by a certain discount ticket broker, 60% are for domestic travel (D) and 40% are for international flights (I). Let x be the number of requests among the next three requests received that are for domestic flights. Assuming independence of successive requests, determine the probability distribution of x. (Hint: One possible outcome is DID, with the probability (.6)(.4)(.6) = .144)
Value of x Probability

Answers

Answer:

We have a binomial probability distribution, in which:

P(X = 0) = 0.064

P(X = 1) = 0.288

P(X = 2) = 0.432

P(X = 3) = 0.216

Step-by-step explanation:

For each flight, there are only two possible outcomes. Either it is for domestic travel, or it is for international travel. Flights are independent of each other. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

Let x be the number of requests among the next three requests received that are for domestic flights.

3 flights, and 60% are for domestic travel. This means that [tex]n = 3, p = 0.6[/tex]. The probabilities are given by:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{3,0}.(0.6)^{0}.(0.4)^{3} = 0.064[/tex]

[tex]P(X = 1) = C_{3,1}.(0.6)^{1}.(0.4)^{2} = 0.288[/tex]

[tex]P(X = 2) = C_{3,2}.(0.6)^{2}.(0.4)^{1} = 0.432[/tex]

[tex]P(X = 3) = C_{3,3}.(0.6)^{3}.(0.4)^{0} = 0.216[/tex]

The city is issuing bonds to raise money for a building project. You obtain a $1000 bond that pays 9% interest annually that matures in 7 years. How much interest will you earn?

Answers

Answer:

$630

Step-by-step explanation:

1000 x .09 = 90

90 x 7 = 630

The interest earned after 7 years = $630

What is Face value?

Face value is a term in finance which is used to explain the nominal value of a security.

For stocks, it is defined as the cost of the stocks and it is defined as the amount paid to the holder after maturity for bonds.

In the question, is is given that $1000 bond is obtained.

Face value of the bond = $1000

The bond pays 9% interest annually.

Interest rate = 9% = 0.09

So the interest you earn annually = face value × interest rate

                                                        = 1000 × 0.09 = $90

The bond matures in 7 years.

Interest earned on maturity = 90 × 7 = $630

Hence, the amount of interest earned after 7 years will be $630.
