How much time does it take for the quarter to hit the water ???

Answers

Answer:

7 seconds

Step-by-step explanation:

y=-16t²+96t+112, where t is time and y is distance above water.

We are looking for t when y=0

-16t²+96t+112=0

t²-6t-7=0

(t-7)(t+1)=0

Either t=7 or t=-1.

Since we cant have negative time, the answer is t=7

The volume, of a rectangular solid with length L, width W, and height H is given by the formula V = LWH.
Use this formula to write a polynomial in standard form that models, or represents, the volume of the open box.
The volume of the open box is ____

Answers

Answer:

[tex]V(x) = 4x^3-34x^2+66x[/tex]

Step-by-step explanation:

Polynomials

We'll apply the polynomials to geometry.

The volume of a rectangular box can be calculated as

V = LWH

Where L is the length, W is the width, and H is the height of the box.

The figure shows the three dimensions as a function of the variable x:

W = 6 - 2x

L = 11 - 2x

H = x

Substituting in the formula of the volume:

[tex]V(x) = (11-2x)(6-2x)(x)[/tex]

Multiplying the first two factors:

[tex]V(x) = (66-22x-12x+4x^2)(x)[/tex]

Simplifying:

[tex]V(x) = (66-34x+4x^2)(x)[/tex]

Multiplying by x:

[tex]V(x) = 66x-34x^2+4x^3[/tex]

Reordering:

[tex]\boxed{V(x) = 4x^3-34x^2+66x}[/tex]

Robin ran 1/2 of a mile. He finished with 2/3 of the race. how long is the whole race?

Answers

Answer: 3/4 mile

Step-by-step explanation:

To find the answer, you divide 1/2 by 2/3. You do KCC so it turns into 1/2 x 3/2. The final answer is 3/4.

So we know that Robin ran 1/2 of a mile and he finish 2/3 of the race.

To find the answer, you divide 1/2 by 2/3.

You do keep change change, so it turns into 1/2 x 3/2 which is 3/4.

Final result: 3/4

A friend has offered to play a gambling game with you that involves flipping a coin that she has provided. You want to test the coin in advance for fairness before agreeing to gamble. Your friend is willing to let you flip it 50 times to determine if the probability of getting heads is actually 0.50, as it should be if the coin is fair. Is it necessary to check the 10% condition in this case

Answers

Answer:

The 10% condition would not apply here

Explanation:

The 10% condition is the recommended size of sample from the population to get a non biased result. The 10% condition requires that the sample be not more than 10% of the population.

Tossing a coin is an example of a Bernoulli trial. A Bernoulli trial is one that has two possible outcomes, this face of the coin or the other face of the coin. The 10% condition does not apply to Bernoulli trials that are independent events.

Therefore the 10% condition would not apply here because tossing a coin is an an independent event. An independent event is one with replacement.

A candy bar that originally sold for $0.65 undergoes a 7% price increase each year. Find the new cost of the candy bar after 15 years. Round your answer to the nearest cent.
The new cost of the candy bar after 15 years is $

Answers

Answer:

10.4325

Step-by-step explanation:

For 1 year:   (0.65) + (0.65)(0.07) = 0.6955

For 15 years: 0.6955 X 15 = 10.4325

All together: (0.65+(0.65*0.07))*15 = 10.4325

The new cost of the candy bar after 15 years is $1.8.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, a candy bar that originally sold for $0.65 undergoes a 7% price increase each year.

Use Amount = Principal(1+R/100)ⁿ, where n is number of years.

Total amount = 0.65(1+7/100)¹⁵

= 0.65(1.07)¹⁵

= 0.65×2.759

= $1.8

Therefore, the new cost of the candy bar after 15 years is $1.8.

I hope this helps you!

Systematic random sampling involves a selection technique in which samples are selected at fixed intervals. Hence, the true statement is "Systematic random sampling can be used, even if knowledge of the entire population is not known."

Systematic random sampling would fail to catch all patterns because the samples are selected at periodically at fixed intervals, hence, the possibility of missing pattern is very possible.

Starting point could be at any point and hence, might not be the first sample in the population.

However, without knowing the entire population size, systematic random samples could be selected from the population.

TS/US=MN/NQ: Let plug in the numbers

3x+1/26=5x-2/39:  Then cross multiply

39(3x+1)=26(5x-2): Then simplify

117x+39=130x-52: Subtract 117x from both sides

39=13x-52: Add 52 to both sides

  91=13x: Divide 13 by both sides

Using the Factor Theorem, it is found that the complete factorization of the polynomial x³ + 8x² + 19x + 12 is given by:

A. (x+4)(x+3)(x+1)

What is the Factor Theorem?

The Factor Theorem states that a polynomial function with roots [tex]x_1, x_2, \codts, x_n[/tex] is given by:

[tex]f(x) = a(x - x_1)(x - x_2) \cdots (x - x_n)[/tex]

In which a is the leading coefficient.

In this problem, using a calculator, the roots of the polynomial x³ + 8x² + 19x + 12 are x = -4, x = -3 and x = -1, hence:

f(x) = (x + 4)(x + 3)(x + 1)

Which means that option A is correct.
