Answer 2

The statements which are true about density curves is the mean of a density curve is indicated by u and the standard deviation of a density curve is indicated by Sx.

What is a density curve?

The density curve is a way of representation of numerical distribution data in graphical manner, where the outcomes are continues. The density curve can not be below the x-axis or horizontal line of the graph.

In a density curve,

The mean of a density curve is indicated by μ (mu).The standard deviation of a density curve is indicated by Sx.The density curve can only be above x-axis and not below it.

Thus, the statements which are true about density curves is the mean of a density curve is indicated by u and the standard deviation of a density curve is indicated by Sx.

Given that 2x + 1 =5, what is the value of (x+3)^3

Answers

Answer: 125

Step-by-step explanation:

First, solve for x in the first equation.

1) Subtract 1 from both sides.

2x = 4

2) Divide by 2 on both sides.

x = 2

Next, substitute the value of x into the second expression.

(2 + 3)^3

= 5^3

= 125

Answer:

The value of (x + 3)³ is 125.

Step-by-step explanation:

First, we have to find the value of x.

To do so, start with the first equation, 2x + 1 = 5.

We can easily solve this equation to find the value of x.

First, start by subtracting 1 from each side.

This leaves us with 2x = 4.

Next, divide by two on each side.

This will leave us with the answer x = 2.

Now we know the value of x = 2.

All that's left to do is substitute the value of x, 2, for x.

First, start with the second equation (x + 3)³.

We know that x is equal to 2, so we can enter 2 for x.

We then have the equation (2 + 3)³.

Next, solve.

Add the 2 and the 3 together.

Now, the equation is 5³.

5³ is equal to 5 · 5 · 5

5 · 5 · 5 = 125

To sum up,

We found out that x = 2

Using 2 for x, we found out that (x + 3)³ is equal to 125.

The perimeter of a rectangle is 36 m. If the length is three times the width, what is the length?

Answers

Answer:

13.5 meters

Step-by-step explanation:

As the rectangle has 4 sides and the length is three times the width, each pair of a long side and a short side has a perimeter of 18 meters. As the ratio is 3:1, there are 4 parts in 18 meters, and 18 divided by 4=4.5. As the length covers 3 parts, and there are 4.5 meters per part, 4.5x3=13.5. The length of the rectangle is 13.5 meters. Hope it helps!

i think its 158

Step-by-step explanation:

i think what theyre doing here is a pattern because

79-55=24 and 110-79=31 which has no pattern but when u subtract 55 from 110 you get  110-55=55  so i just multiplied 79 by 2 getting the answer 158.

What is the next number in the pattern below?

3, 9, 27, 81

Answers

Answer:

243

Step-by-step explanation:

the reason why it's 243 is because 3 x 3 = 9, 9 x 3 = 27, and 81 x 3 = 243.

Answer: Step-by-step explanation: 243

Lets look at the difference between the first two numbers (3 and 9). to get from 3 to 9, we either have to multiply by 3, or add 6.

Next, let's look at the difference between 9 and 27. to get from 9 to 27, you have to multilpy by 3, or add 18.

If we conitnue to multiply the previous by 3, we get the following number, therefore we know the answer is to multiply by 3.

if we multiply 81 by 3, we get 243

So, 54 = 9A

A = 6

Now, since distance = 78,

78 = time * A

From above, we can see that A = 6, so

78 = time *6

time = 13

Kiera and Trina joined a gym. The gym offers two different payment plans. Kiera chose Plan 1 and pays $25 a month and no fee to join. Trina chose Plan 2 and pays $10 a month, plus a $100 joining fee. Which equation models Kiera’s total payments, t1, and Trina’s total payments, t2, after m months?

Answers

Answer:

t1 = $25m

t2 = $(10m + 100)

Step-by-step explanation:

Here we want to write equations

Kiera chose plan 1

$25 monthly and no joining fee

So the amount after m months will be 25 * m

t1 = $25m

Trina chose plan 2

$10 a month and $100 joining fee

after m months , total payment will be

10(m) + 100 = $(10m + 100)

Thus t1 = $25m and t2 = $(10m + 100)

Passage 2: Excerpt from School Bus Ads Bring Needed Revenue to Area Districts18 School buses are carrying more than students these days.19 The vehicles sport fancy advertisements for local businesses and events.20 It's part of the effort for school districts to make money in these budget-strapped times.21 And it is paying off.22 Lewis-Palmer School District 38 made about $8,000 in its first effort last year with eight advertisers and 11 buses. This year, it is expanding.23 "Ultimately we hope to have advertisements on every bus to maximize our income," said Robin Adair, D-38 spokeswoman. The district, which has had $11 million in cuts in recent years, is seeking a $4.5 tax increase in the November election.24 D-38 has 56 buses that collectively travel more than a half million miles a year. That could be a lot of bang for the advertising buck, and a nice amount of change for district coffers. Like Lewis-Palmer, most districts that allow advertising on their buses choose to put the money in general funds to help with such things as higher fuel and utility expenses and increased contributions to pension funds and student activities.25 Other Pikes Peak districts that use their buses as rolling billboards are Colorado Springs School District 11 and Falcon School District 49.26 Some of the advertisements on Lewis-Palmer buses include dentists, restaurants, insurance agents, a gymnasium, PTA's and the district's own programs.27 A.B. Tellez, owner of Rosie's Diner in Monument, said he signed up for two buses, one middle school that features kid's meals and shakes, and an elementary bus that features, of course, chicken nuggets. "Those buses drive everywhere. It's awesome marketing. But there is more to it than that. It's being part of the community, helping out the schools. They need funds. I thought it was neat to use dollars to support the community as well as the community supporting us."28 The districts report that the ads are approved by administrators before they are placed on the buses. There are none inside the buses to entice kids. The products must be child friendly -- no alcohol, tobacco, gaming or distasteful subjects. They don't usually allow advertising from other schools that might compete with them for students.29 Colorado in 1997 was the first state to allow school-bus advertising.(the question)Which quote from Passage 2 provides evidence that many school districts are dealing with budgetary concerns?A)"Lewis-Palmer School District 38 made about $8,000 in its first effort last year with eight advertisers and 11 buses."
