The school sold 300 tickets to the theatre performance. They sold adult tickets for $9 each and student tickets for $6 each. They made a total of $2, 190. How many students were in attendance?

PLEASE HELP! I need to show work

Answers

Answer:

170 students were attending

Step-by-step explanation:

use a system of equations:

[tex]\left \{ {{x+y=300} \atop {9x+6y=2190}} \right.[/tex]  

let x be the adults and y be the students

[tex]\left \{ {{-9(x+y=300)} \atop {9x+6y=2190}} \right.[/tex]    multiply the top equation by -9 and add the two systems together to cancel out x. you are then left with:

[tex]-3y=-510[/tex]

divide both sides by -3 to leave y alone:

[tex]\frac{-3y}{-3}=\frac{-510}{-3}[/tex]

that would leave you with:

y=170

Three years ago A's age was double of B's
age. Seven years hence, the sum of their
ages will be 83 years. Find the present
age of A?​

Answers

Answer:

present Age of " A " will be (x) = 45 years

present Age of " B " will be (y) = 24 years

Step-by-step explanation:

Age of " A " = x years

Age of " B " = y years

(Three years ago A's age was double of B's age.)

==> (x-3) = 2 * (y-3)

==> x - 2y = -6 + 3

==> x - 2y = -3 -------------(1)

(Seven years hence, the sum of their ages will be 83 years )

==> (x+7)+(y+7) = 83

==> x + y = 83 - 14

==> x + y = 69 ------------(2)

Subtract equ.(1) & equ(2)

==> -2y - y = -3 - 69

==> -3y = -72

==> y = -72/(-3)

==> y = 24

Keep value of y in equ(2)

==> x + 24 = 69

==> x = 69 - 24

==> x = 45

The volume of a cube, in cubic centimeters, is given by the function V(x) = x3, where x is the side length of the cube in centimeters. Write a new function for the volume of the cube in cubic millimeters.

Answers

I think we can all agree that 1 centimeter=10millimeters.

And if x is the side in centimeters then 10x will be the side in millimeters.

We just need to rewrite x^3 into (10x)^3.

Because you need to do the exponent to all part of the ( )...

(10x)^3=1000x^3

V(x)=1000x^3 cubic millimeters is the answer

Hence, a new function for the volume of the cube in cubic millimeters is [tex]V(x)=1000x^3[/tex].

What is the volume of cube?

The volume of a cube is defined as the total number of cubic units occupied by the cube completely.

A cube is a three-dimensional solid figure, having six square faces. Volume is nothing but the total space occupied by an object.

Here given that,

The volume of a cube, in cubic centimeters, is given by the function [tex]V(x) = x^3[/tex], where [tex]x[/tex] is the side length of the cube in centimeters.

As, [tex]1[/tex] centimeter=[tex]10[/tex]millimeters.

If the side is [tex]x[/tex] then the side in millimeter is [tex]10x[/tex].

So, we have [tex]x^3[/tex] which would be [tex](10x)^3[/tex]

[tex](10x)^3=1000x^3[/tex]

Then,

[tex]V(x)=1000x^3[/tex] cubic millimeters.

Hence, a new function for the volume of the cube in cubic millimeters is [tex]V(x)=1000x^3[/tex].

4x-5y=11 and 8x-5y=27

Answers

Answer:

y = -1 , x = 4

Step-by-step explanation:

(4x - 5y = 11) x8

(8x - 5y = 27) x4

32x - 40y = 88

- - -

32x - 20y = 108

[0. 20y = -20] divide both by 20

y = -1

8x - 5y = 27

8x - 5(-1) = 27

8x = 27 + 5

8x = 32 ( divide both by 8)

The local ranger station tracked and tagged 2,844 adult female black bears in a national park. A random sample of 9 adult female black bears from those tagged had an average body weight of 203 pounds with standard deviation 25 pounds. Which of the following is a point estimate for the population mean weight of all female black bears that are tagged?

a. 9
b. 25/√9
c. 25
d. 203
e. 2,844

Answers

Answer:

203

Step-by-step explanation:

Sample size, n = 9

Mean weight, m = 203

Standard deviation = 25

Point estimate for the population mean weight of all black bears that are tagged `

The point estimate of the population mean ;

ΣX / n

Sum of sample / sample size ;

This is the mean value formula for the sample.

However, since it has been given in the question that, sample mean weight value = 203 ; then the point estimate of the population mean weight = 203

Option d: 203 is a point estimate for the population mean weight of all female black bears that are tagged.

Given that:Total tagged adult female black bears in the national park = 2,844Sample size = 9Sample mean of body weight of female black bears = 203 pounds.To find:

Point estimate of population mean weight of female black bears that are tagged.

Calculations and explanations:

Point estimation of population mean is calculated by calculating the mean of the sample drawn from that population. This estimate is considered best guess of population mean.

The sample mean is obtained by:

[tex]\overline{x} = \dfrac{\sum \text{sample observations}}{\text{sample size}}[/tex]

Since it is given that the sample mean is 203, thus we have the point estimate of the population mean as 203 too.

Thus, 203 is a point estimate for the population mean weight of all female black bears that are tagged.

An article describes a study in which a new type of ointment was applied to forearms of volunteers to study the rates of absorption into the skin. Eight locations on the forearm were designated for ointment application. The new ointment was applied to four locations, and a control was applied to the other four. How many different choices were there for the four locations to apply the new ointment

Answers

Answer:

There were 70 choices for the four locations to apply the new ointment

Step-by-step explanation:

The order in which the locations are chosen is not important. So we use the combinations formula to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

How many different choices were there for the four locations to apply the new ointment

Four locations from a set of 8. So

[tex]C_{8,4} = \frac{8!}{4!(8-4)!} = 70[/tex]

There were 70 choices for the four locations to apply the new ointment

The 59th and 4th team of an Ap are - 61 and 64 respectively. Show that the common differences is - 2.5 and 23rd term is 16.5​

Answers

Answer:

See answers below

Step-by-step explanation:

T59 = a+58d = -61

T4 = a+3d = 64.

Subtract

58d-3d = -61-64

-55d = -125

d =125/55

d = 25/11

Get a;

From 2

a+3d = 64

a+3(25/11) = 64

a = 64-75/11

a = 704-75/11

a = 629/11

T23 = a+22d

T23 = 629/11+22(25/11)

T23 = 1179/11
