Answers

Answer:

6x^2+11x+3

Step-by-step explanation:

Area= Length*Width

Area= (3x+1)(2x+3)

Use method FOIL (Front,Out,In,Last)

(3x*2x)+(3x*3)+(2x*1)+(3*1)

= 6x^2+9x+2x+3

Zeke kicked a football 92 yards. Zane estimated it at 90 yards. What percent error did Zane make? If a decimal, round the percent to 2 decimal places.

Answers

Answer:

Zeke had a 2.17% margin of error in his estimation.

Step-by-step explanation:

To set this problem up, you would need to create a proportion. X, the percent of error you're trying to find, should be over 100%. It should look like:

2/92 = X/100

This would translate your terms, the distance the football was kicked, into percentage terms. You should have 2/92 rather than 90/92. 90/92 would give you how accurate Zeke's estimate was instead of is percent of error.

Cross-multiply your numbers:

(2)(100) = 92X

200 = 92X

X = 2.1739

Then, once you round it, your answer would be X = 2.17.

A hospital bill is estimated to be $480.00. It ends up actually costing the patient $524.50. What is the percent of error in the bill? Round to the nearest tenths place.

Answers

Answer: 8.484%

Step-by-step explanation:

The formula for percentage error is calculated as:

= (actual value observed - expected value) / expected value × 100

where,

Actual value observed = $480.00

Expected value = $524.50

Percent error = ($480.00 - $524.50)/$524.50 × 100

= -$44.50/$524.50 × 100

= -0.08484 × 100

= -8.484

= 8.484%

Sara owns a tree farm. Variety A of a pine tree is shipped to her at 12 inches tall and grows at a rate of 14 inches per year. Variety B of a pine tree is shipped to her at 2 inches tall and grows at a rate of 16 inches per year

What is the general equation of a Straight line?

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have Sara owns a tree farm. Variety A of a pine tree is shipped to her at 12 inches tall and grows at a rate of 14 inches per year. Variety B of a pine tree is shipped to her at 2 inches tall and grows at a rate of 16 inches per year.

Variety [A] = 14x + 12

Variety [B] = 16x + 2

The equation that can be used to determine the number of years at which the trees will be an equal height is -

14x + 12 = 16x + 2

Therefore, the equation that can be used to determine the number of years at which the trees will be an equal height is -

14x + 12 = 16x + 2

Can someone help me with the questions in the picture?

Answers

Answer:

9. Perpendicular

10. neither

11. Perpendicular

12. neither

Step-by-step explanation:

------------------

Slope Intercept Form: y = mx + b

* M is the slope

* B is the y intercept

------------------

Lines are parallel if they have the same slope (ex. If two equations have a slope of 2)

Lines are perpendicular if they have the opposite and the reciprocal slope (ex. If 1 equation has a slope of 3 and another equation has a slope of - [tex]\frac{1}{3}[/tex] )

------------------

9. Perpendicular: The slopes are reciprocal of each other and one of them is negative

10. Neither: The lines are not perpendicular because the slopes are both negative

11. Perpendicular: If you plot y=5 it is a horizontal line through 5. If you plot x=-3 it is vertical line through -3. These lines intercept and are perpendicular.

12. Neither: The slopes of both equations need to be the same to be parallel

Put both equations into y=mx+by = 1/2x -2 AND y = -1/2x -2

The ratio of right-handed students to left-handed students is 8 to 3.There are 520 right-handed students in school.How many students are left-handed

Answers

Answer:

195 students are left-handed

Step-by-step explanation:

Here, we want to calculate the total number of students who are left-handed

Let the total number of students in the school be x

The total ratio is 8 + 3 = 11

8/11 * x = 520

8x = 11 * 520

x = (11 * 520)/8

x = 715 students

So the number of students who are left handed will be;

Total - number of right-handed students

That would be;

715-520 = 195

Angie and Kenny play online video games. Angie buys 1 software package and 1month of gameplay. Kenny buys 1 software package and 2 months of game play. Each software package costs ​$30. If their total cost is ​$90​, what is the cost of one month of gameplay?

Answers

Answer: $10

Step-by-step explanation:

Angie buys = 1 software package and 1month of gameplay.

Kenny buys = 1 software package and 2 months of game play.

Cost of each software package = $30. Total cost = ​$90​

The total cost is the addition of what Kenny and Angie bought. This will be:

(1 SF + 1 G) + (1 SF + 2 G) = 90

where,

SF = software package = 30

G = game

(1 SF + 1 G) + (1 SF + 2 G) = 90

30 + 1G + 30 + 2G = 90

60 + 3G = 90

3G = 90 - 60

3G = 30

G = 30/3

G = 10

One month of game play cost $10

Suppose babies born in a large hospital have a mean weight of 3831 grams, and a variance of 108,900. If 65 babies are sampled at random from the hospital, what is the probability that the mean weight of the sample babies would be less than 3882 grams? Round your answer to four decimal places

Answers

Answer:

0.8944

Step-by-step explanation:

We start by calculating the z-score

To calculate the z-score, we shall need the standard deviation

Mathematically, standard deviation is square root of variance

that will be; SD = √108,900 = 330

Formula for z-score is;

x-mean/SD/√n

where n is 65 in this case

z-score = (3882-3831)/330/√65 = 1.25

The probability we want to calculate is;

P( X < 1.25)

we can use the standard normal distribution table for this

Using the table;

P( X < 1.25) = 0.89435 which is 0.8944 to 4. decimal places

Vaping is good for you because it doesnt do anything. Weed is good for you because it helps you calm down and forget. These are perfect examples as to why they are not good. Vaping damages your lungs and can give your body cancer. Over time, smoking weed may cause chronic cough and other health issues. Both vaping, weed, cigarettes, alcohol, and many more drugs are not good for you or your body.Drugs are used across the world. Whether they are used properly or abused. Drugs are easy to become addicted to. They can cause substance abuse, which leads to jail time. While drugs also heal people, for example, prescription drugs when used properly are beneficial. They need to be used in restraint because even medically given to you, they are addictive. For example, pain-reducing opioids, though they are helpful they are addictive. All minds are affected; it's not just a teenager thing. Drugs should be monitored by someone, and while it is slightly out-of-pocket, it's a lot better than spending possible years in prison.Vaping may be a little better than weed or cigarettes but it still harms your body in multiple ways. It causes you to crave and if you dont follow that craving it will lead to withdrawal symptoms. Nicotine is an addictive chemical. It is a toxic substance. It raises your blood pressure and spikes your adrenaline, which then increases your heart rate. Increased heart rate can conclude to having a heart attack.An abundance of alcohol can harm the liver. This can lead to hepatitis, which is the buildup of scar tissue that eventually destroys the organ. Alcohol may cause kidney, bladder, and prostate inflammation. Alcohol is also an addictive substance, though alcohol may relieve pain and make you forget things, too much will make you drunk and incoherent.Opioids are a class of drugs used to reduce pain.
