Answer:

We know nothing about Dylan so we can not write an expression about dylans weight.

Step-by-step explanation:

B- Bruce's Weight

A- Alan's Weight

B-A= H

Where H is how many more pounds that Bruce weighs than Alan.

Answer:

Bruce's weight in terms of Dylan's weight is 3d-12.

Alan's weight in terms of Dylan's weight is 2d+3

So, the expression (3d-12) -(2d+3) represents how much more  Bruce weighs than Alan.

Hey there!

When dealing with percent word problems, the word "is" means equals. Let's see what we can do with your problem.

If the small school had 60% boys, it will have 40% girls. The number of boys is 48, which should equal 60% of the total, which we can model below, with t representing the total number of kids. In decimal form, 60% is 0.6.

0.6t=48

We divide both sides by 0.6.

t=80

Therefore, there are 80 total kids at the school.

We can also check our answer below.

BOYS: 0.6(80)= 48

GIRLS: 0.4(80)=32

48+32=80

I hope that this helps!

Hi there!

Answer:

-14.98%(or -15%).

Step-by-step explanation:

1)To find the percent decrease,all you have to do is minus the original number from the decreased amount so:

1435-1220= 215

2)Then you divide this answer by the original number again so:

215÷1435= 0.1498

3)Then you times the decimal by 100 so:

0.1489x100= -14.98%(or -15%).

Answer:

C.

Step-by-step explanation:

Lines with equal slopes are parallel since their slopes are equal so they are parallel.

Answer:

32%

Step-by-step explanation:

Given

Cost of Crockpot = $125

Coupon = $40

Coupon applies on items greater than $100

Required

Percent saved if coupon is applied.

If she applies coupon on the Crockpot, then she'll be saving $40.

Percent Savings = Amount Saved / Total Amount

Percent Savings = $40/$125

Percent Savings = 0.32

Convert to Percentage

Percent Savings = 0.32 * 100%

Percent Savings = 32%.

Hence, she'd save 32% if she applies the coupon of $40 on the Crockpot

Answer:

percentage savings = 32%

Step-by-step explanation:

She is buying a Crock-pot that retails for $125 . She has a coupon for $40 off any time she bought over $100 item.

Her percentage saving can be calculated below.

The price of the crock-pot is $125 but the amount she bought it base on coupon she has will be $125 - $40 = $85.

The normal price of the crock-pot is $125 and she bought it base on her coupon for $85, then the percentage change is

percentage saving = amount saved/normal price × 100

percentage savings = 40/125 × 100

percentage savings = 4000/125

percentage savings = 32%

The amount you bought the crock-pot was less than the original price hence Felicia saved 32% of the original price.

Answer:

45 sides

Step-by-step explanation:

If each of the interior angles is 172 degrees, then each of the exterior angles is 8 degrees. Since the sum of the exterior angles of any polygon is 360 degrees, there are 360 / 8 = 45 exterior angles and 45 sides.

Answer:

It costs $154.88 to build the fences.

Step-by-step explanation:

Perimeter of square = [tex]4 \times Side[/tex]

We are given that A garden is in the shape of a square with a perimeter of  56 feet.

So,[tex]4 \times side = 56[/tex]

Side =[tex]\frac{56}{4}=14 feet[/tex]

So, Side of square park = 14 feet

One fence is around the perimeter of the garden, whereas the second fence is 2 feet from the first fence on the outside.

Outer length = 14+2+2=18 feet

So, Perimeter of outer fence = [tex]4 \times side = 4 \times 18 = 72 feet[/tex]

Cost of fencing 1 foot = $1.21

Cost of fencing 56 feet =[tex]56 \times 1.21=67.76[/tex]

Cost of fencing 72 feet = [tex]72 \times 1.21=87.12[/tex]

Total cost = 67.76+87.12=154.88

Hence It costs $154.88 to build the fences.

Answer: C. Her probability of winning is dependent event because it depends on the results of her friends rolls.

Step-by-step explanation: In probability, dependent event is an event that is affected by the outcome of another event.

In a dice there are 6 possibilities: numbers 1, 2, 3, 4, 5 and 6. To win the game, Taylor has to roll a number higher than 1 or 3, i.e. she has to roll the numbers 4, 5 or 6.

The probability of that happening is: P(a) = 3/6 = 1/2 = 50%.

Therefore, the events are dependents, because it depended on the outcome of the friends playing the game.

Answer:

D

Step-by-step explanation:

Yes, it does because it passes the vertical line test. We don't have to worry about the horizontal line test because it isn't a valid test. For example, let's imagine a parabola. That doesn't pass the horizontal line test, but it's still a function. This means that we can eliminate option B. We can do the same to C because a function doesn't necessarily have to be a straight line (like the parabola). That leaves us with options A and D. These both have to do with the vertical line test, so let's do it! If we place a vertical line anywhere on this graph, we will see that there are no vertical lines that intersect at 2 places with the graph. Therefore, it passes the vertical line test, and is a function. Hope this helps!

Step-by-step explanation:

Hello!

To see if driving heavy equipment on wet soil compresses it causing harm to future crops, the penetrability of two types of soil were measured:

Sample 1: Compressed soil

X₁: penetrability of a plot with compressed soil.

n₁= 20 plots

X[bar]₁= 2.90

S₁= 0.14

Sample 2: Intermediate soil

X₂: penetrability of a plot with intermediate soil.

n₂= 20 (with outlier) n₂= 19 plots (without outlier)

X[bar]₂= 3.34 (with outlier) X[bar]₂= 2.29 (without outlier)

S₂= 0.32 (with outlier) S₂= 0.24 (without outlier)

Outlier: 4.26

Assuming all conditions are met and ignoring the outlier in the second sample, you have to construct a 99% CI for the difference between the average penetration in the compressed soil and the intermediate soil. To do so, you have to use a t-statistic for two independent samples:

Parámeter of interest: μ₁-μ₂

Interval:

[(X[bar]₁-X[bar]₂)±[tex]t_{n_1+n_2-2;1-\alpha/2}[/tex]*Sa[tex]\sqrt{\frac{1}{n_1} +\frac{1}{n_2} }[/tex]]

[tex]t_{n_1+n_2-2;1-\alpha/2}= t_{20+19-2;1-(0.01/2)}= t_{37; 0.995}= 2.715[/tex]

[tex]Sa= \sqrt{\frac{(n_1-1)S_1^2+(n_2-1)S_2^2}{n_1+n_2-2} } = \sqrt{\frac{19*0.0196+18*0.0576}{20+19-2} }= 0.195= 0.20[/tex]

[(2.90-2.29)±2.715*0.20[tex]\sqrt{\frac{1}{20} +\frac{1}{19} }[/tex]]

[0.436; 0.784]

I hope this helps!

Using the t-distribution, it is found that the 99% confidence interval for the decrease in penetrability of compressed soil relative to intermediate soil is (-0.418, 1.182).

Using a calculator, we find that for the compressed soil, the mean and the standard deviation are given by:

[tex]\mu_C = 2.9075, s_C = 0.1427[/tex]

For the intermediate soil, omitting the high outlier of 4.26, we have that:

[tex]\mu_I = 3.2895, s_I = 0.2385[/tex]

The distribution of the decrease has mean and standard deviation given by:

[tex]\overline{x} = \mu_I - \mu_C = 3.2895 - 2.9075 = 0.382[/tex]

[tex]s = \sqrt{s_C^2 + s_I^2} = \sqrt{0.1427^2 + 0.2385^2} = 0.2779[/tex]

The interval is given by:

[tex]\overline{x} \pm ts[/tex]

By the conservative method, the amount of degrees of freedom is one less than the smaller sample size, which in this case is 19, for the intermediate soil.

Then:

[tex]\overline{x} - ts = 0.382 - 2.8784(0.2779) = -0.418[/tex]

[tex]\overline{x} + ts = 0.382 + 2.8784(0.2779) = 1.182[/tex]

The 99% confidence interval for the decrease in penetrability of compressed soil relative to intermediate soil is (-0.418, 1.182).

And replacing the info we got:

[tex] V = 30.38 yd^2 * 3.8 yd = 115.44 yd^3[/tex]

Answer:

Volume = 115.44 cubed yard

Step-by-step explanation:

Given that ;

base area = 30.38 square yards

height = 3.8 yards. ​

The volume for a rectangular prism is length * width * height

Area = length * width

we are given area = 30.38 square yards

Volume = Area * height

Volume = 30.38 square yards *  3.8 yards. ​

Volume = 115.44 cubed yard

Therefore, the answer is  = 115.44 cubed yard

Answer:

Step-by-step explanation:

Since the diagram to this question is not given ; we will just explain the concept of the right angled triangle and a means by which we can use the Pythagoras theorem in solving such related question.

A right angled triangle has to legs which serves as the base line in which the height of the right angle is 90°.

Now; If we have a base line AB; let say , we chose any convenient radius at a and bisect an arc. at the arc we make another arc to the right ; we will have an angle at A which is 60°, So B will form a straight line up serving the role of the right angle which is 90° and where both met will be C which is 30°

So now we have a triangle ABC, if the line facing ∠ A = a ; the line facing ∠ B = b and the line facing ∠ C = c

Then; we can solve for side c if ; side a and side b are known by using the Pythagoras theorem.

Using Pythagoras theorem.

a²  = b² + c²

-c² =  b² - a²

Multiplying through with -

c² = - b² + a²

[tex]\mathbf{ c = \sqrt{-b^2 + a^2}}[/tex]

Since ; we already make c the subject of the formula; from the missing diagram, we can easily slot the values of a and b given to solve for the value of c using the above derived equation.

I hope that helps!.
