Answers

Answer:

35 Meters

Step-by-step explanation:

Ratio is 12

What I mean by that is 2 turns into 24 because you multiply 12 to it. Same thing for 420, except for the fact that you divide it (working backwards). So 420 divided by 12 equals 35:)  Enjoy your day

Wayne has 16 3/4 gallons in his car. If he used 2/5 of the gas in his car, how many gallons does he have left

Answers

Answer:

Wayne has 10.05 gallons left.

Step-by-step explanation:

16 3/4 times 2/5 is 6.7

16 3/4 minus 6.7 is 10.05

Wayne has 327/20 gallons of fuel left in his car.

What is a fraction?

Fractions represent the parts of a whole or collection of objects. A fraction has two parts. The number on the top of the line is called the numerator.The number on the bottom of the line is called the denominator.

Now it is given that,

Amount of fuel in the car = 16 3/4 gallons = 67/4 gallons

Amount of fuel used = 2/5 gallons

Therefore,

Amount of fuel left in the car = Amount of fuel in the car - Amount of fuel used

⇒ Amount of fuel left in the car = 67/4 - 2/5

⇒ Amount of fuel left in the car = 327/20 gallons

Thus, Wayne has 327/20 gallons of fuel left in his car.

Bottles of mango juice are assumed to contain 275 milliliters of juice. There is some variation from bottle to bottle because the filling machine is not perfectly precise. Usually, the distribution of the contents is approximately Normal. An inspector measures the contents of seven randomly selected bottles from one day of production. The results are 275.4, 276.8, 273.9, 275.0, 275.8, 275.9, and 276.1 milliliters. Do these data provide convincing evidence at α = 0.05 that the mean amount of juice in all the bottles filled that day differs from the target value of 275 milliliters? (4 points)


Group of answer choices


Because the p-value of 0.0804 is greater than the significance level of 0.05, we fail to reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day does not differ from the target value of 275 milliliters.


Because the p-value of 0.0804 is greater than the significance level of 0.05, we reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day differs from the target value of 275 milliliters.


Because the p-value of 0.1609 is greater than the significance level of 0.05, we fail to reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day does not differ from the target value of 275 milliliters.


Because the p-value of 0.1609 is greater than the significance level of 0.05, we reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day differs from the target value of 275 milliliters.


Because the p-value of 1.5988 is greater than the significance level of 0.05, we fail to reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day does not differ from the target value of 275 milliliters.

Answers

Answer:

The correct option is;

c. Because the p-value of 0.1609 is greater than the significance level of 0.05, we fail to reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day does not differ from the target value of 275 milliliters.

Step-by-step explanation:

Here we have the values

μ = 275 mL

275.4

276.8

273.9

275

275.8

275.9

276.1

Sum = 1928.9

Mean (Average), = 275.5571429

Standard deviation, s = 0.921696159

We put the null hypothesis as H₀: μ₁ = μ₂

Therefore, the alternative becomes Hₐ: μ₁ ≠ μ₂

The t-test formula is as follows;

[tex]t=\frac{\bar{x}-\mu }{\frac{s}{\sqrt{n}}}[/tex]

Plugging in the values, we have,

Test statistic = 1.599292

[tex]t_{\alpha /2}[/tex] at 7 - 1 degrees of freedom and α = 0.05 = ±2.446912

Our p-value from the the test statistic = 0.1608723≈ 0.1609

Therefore since the p-value = 0.1609 > α = 0.05, we fail to reject our null hypothesis, hence the evidence suggests that the mean does not differ from 275 mL.

Answer:

Because the p-value of 0.1609 is greater than the significance level of 0.05, we fail to reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day does not differ from the target value of 275 milliliters.

Joanna has been saving for retirement for 40 years. She made monthly deposits of $275 and earned 5.6% annual interest, compounded monthly. According to her account documents, after these 40 years, she has a balance of $491,730.35 in her account. How much of this did Joanna contribute and how much of this is interest?

Answers

Joanna deposited $132000 and her interest amount is $359730.35

Step-by-step explanation:

Monthly deposit = $275

Interest = 5.6%

Time = 40 years

After 40 years her account balance = $491730.35

If she deposit $275 monthly then after 40 years she will have deposited ,

= 275 x 12 x 40

= $132000

The remaining is her interest amount.

Interest amount = 491730.35 - 132000

= $359730.35

Joanna deposited $132000 and her interest amount is $359730.35

Step-by-step explanation:

Given

= 3ab + ac - 6b² - 2bc (factor the first/second and third/fourth terms )

= a(3b + c) - 2b(3b + c) ← factor out (3b + c) from each term

Let's rearrange

3ab+ac-6b^2-2bc

Let's factorise

a(3b+c)-2b(3b+c)

(a-2b)(3b+c)

Since the answer cannot be solved further

By what percent will the fraction change if its numerator is

Answers

Answer:

The fraction increase by ( [tex]0.047=4.7\:\%[/tex] ) if its numerator is

increased by 25% and its denominator is increased by 20%.

Step-by-step explanation:

Let 'n' be the numeratorLet 'd' be the denominator

As

[tex]100\%\mathrm{\:in\:fractions}=\:1[/tex]

[tex]25\%\mathrm{\:in\:fractions}=\:\frac{1}{4}[/tex]

[tex]20\%\mathrm{\:in\:fractions}=\frac{1}{5}[/tex]

so

Increase in 25% means

[tex]100\%\:+25\%\:=\frac{5}{4}[/tex]    

Increase in 20% means

[tex]100\%\:+20\%\:=\frac{6}{5}[/tex]

Thus the fraction becomes

[tex]\:\frac{\frac{5}{4}\times \:n}{\frac{6}{5}\times \:d}[/tex]                  

[tex]=\frac{\frac{5}{4}n}{\frac{6d}{5}}[/tex]

[tex]\mathrm{Divide\:fractions}:\quad \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\times \:d}{b\times \:c}[/tex]

[tex]=\frac{5n\times \:5}{4\times \:6d}[/tex]

[tex]=\frac{25n}{24d}[/tex]

[tex]=1.0417\left(\frac{n}{d}\right)[/tex]

[tex]=1\left(\frac{n}{d}\right)+0.047\left(\frac{n}{d}\right)[/tex]

As

[tex]0.047=4.7\:\%[/tex]

Therefore, the fraction increase by ( [tex]0.047=4.7\:\%[/tex] ) if its numerator is

increased by 25% and its denominator is increased by 20%.

Elsa saving money to buy a game so far she had saved $36 which is 3/4 of the total cost of the game how much does the game cost

Answers

Answer:

$48

Step-by-step explanation:

To figure out how much the game costs in total, we first need to divide $36 by 3 (3 is the numerator).

36 / 3 = 12

The number 12 is how much each quarter is worth as shown below.

1/4 = 12

2/4 = 24

3/4 = 36

4/4 = ?

To find the answer, all we do is add 12 to 36.

12 + 36 = $48

Answer:

$48

Step-by-step explanation:

Let x represent the cost of the game

$36 = 3/4 x

Divide both sides by 3/4

$36/3/4 = x

$36 *4 / 3 = x

$48 = x

Therefore, the game costs $48

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Here are the steps to find whether each cube root or square root lies between 2 and 3, 4 and 5, or 9 and 10:

Start with the first cube root or square root, ∛800.

Estimate the value of the root.

For ∛800, we can estimate that it's between 8 and 9, since 8 cubed is 512 and 9 cubed is 729.

So, ∛800 must be somewhere in between.

Determine which range the estimated value falls into.

Since 8 is between 2 and 3, ∛800 must also be between 2 and 3.

Repeat the process for the remaining cube roots and square roots, using the same ranges.

Here are the results:

∛800: Between 2 and 3

∛101: Between 4 and 5

∛90: Between 4 and 5

∛20: Between 2 and 3

√7: Between 2 and 3

√20: Between 4 and 5

√90: Between 9 and 10

Thus,

Four of the roots lie between 2 and 3, two lies between 4 and 5, and one lies between 9 and 10.
