Step-by-step explanation:

Step 1: Define

2h = 81² - 19²

Step 2: Solve for h

Answer:

2h = 81^2 - 19^2

2h = 6561 - 361

2h = 6200

h = 6200/2

h = 3100

Answer:

380-5%

Step-by-step explanation:

Answer:

£399

Step-by-step explanation:

personally its easier to find 1% first then multiply it by how many percent are needed to be found.

380/100=1%

380/100=3.8

3.8x5=5%

3.8x5=19

380+19=usual price

380+19=199

Answer:

Step-by-step explanation:

a 30-60-90 right triangle is a right triangle because of the 90

the 30 and the 60 have to make 90 too since traingles make 180

30 + 60 + 90 = 180

so 30-60-90 is a right triangle.

Right triangles also can use pythagoran theorem, so the angle ratio is

30-60-90

but the side ratio is

a² + b² = c²

Answer:

right,scalene triangle

We are given the following information:

each person uses 3/8 a box

there are 6 boxes

Because each box is , and there are 6 boxes, we know that 1 person is , or .

In order to find how many people can use the 6 boxes, we can divide it by 3 (for each use):

48 / 3 = 16

Therefore, 16 people can share the worms.

Answer:

we need to know whats given above can you show us a picture of the table above?

Step-by-step explanation:

Answer:

90 Pomegranate and 55 iZac

Step-by-step explanation:

Represent Pomegranate with p and iZac with i

The data can be represented in the following table.

[tex]\begin{array}{cccc}{} & {Pomegranate} & {iZac} & {Total} & {Memory} & {400} & {300} & {52500} & {Disk\ Space} & {80} & {100} & {12700} \ \end{array}[/tex]

The table can be represented as follows:

[tex]400p + 300i = 52500[/tex] --- (1)

[tex]80p + 100i = 12700[/tex] ---- (2)

Multiply equation (2) by 3

[tex]3 *\ ([/tex][tex]80p + 100i = 12700[/tex][tex])[/tex]

[tex]240p + 300i = 38100[/tex] ---- (3)

Subtract (3) from (1)

[tex]400p - 240p + 300i - 300i = 52500 - 38100[/tex]

[tex]160p = 14400[/tex]

Divide both sides by 160

[tex]p = 90[/tex]

Substitute [tex]p = 90[/tex] in (2)

[tex]80p + 100i = 12700[/tex]

[tex]80 * 90 + 100i = 12700[/tex]

[tex]7200 + 100i = 12700[/tex]

Collect like terms

[tex]100i = 12700 - 7200[/tex]

[tex]100i = 5500[/tex]

Divide by 100

[tex]i = 55[/tex]

So;

[tex]p = 90[/tex] and [tex]i = 55[/tex]

Using set operations,

1.The number of students who study all the three subjects = 10

2.The number of students who study only mathematics and chemistry = 8

Set operations are the operations that are applied on two or more sets to develop a relationship between them. There are four main kinds of set operations which are as follows.

Let mathematics = M, physics = P, chemistry = C.

n(M∪P∪C) = 80

n(M) = 48

n(P) = 40

n(C) = 44

n(M∩P) = 20

n(M∩C) = ?

n(C∩P) = 24

n(M∩P) + n(M∩C) + n(C∩P) - 3n(C∩P∩M) = 32

20 + n(M∩C) + 24 - 3n(C∩P∩M) = 32

n(M∩C) = 3n(C∩P∩M) - 12 - *

We know,

n(M∪P∪C) = n(M) + n(P) + n(C) - n(M∩P) - n(M∩C) - n(C∩P) + n(C∩P∩M)

80 = 48 + 40 + 44 - 20 - n(M∩C) - 24 + n(C∩P∩M)

n(M∩C) = n(C∩P∩M) + 8 - **

Equating * and **,

n(C∩P∩M) + 8 = 3n(C∩P∩M) - 12

2n(C∩P∩M) = 20

n(C∩P∩M) = 10

putting the value of n(C∩P∩M) in *

n(M∩C) = 18

n(M∩C) - n(C∩P∩M) = 8

Answer:

They are less than 1/2

Step-by-step explanation:

Answer:

The 95% confidence interval for the true average strain is between 23.94% and 28.06%.

Step-by-step explanation:

We have the standard deviation of the sample, so we use the t-distribution to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 13 - 1 = 12

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 12 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 2.18

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 2.18\frac{3.4}{\sqrt{13}} = 2.06[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 26 - 2.06 = 23.94

The upper end of the interval is the sample mean added to M. So it is 26 + 2.06 = 28.06

The 95% confidence interval for the true average strain is between 23.94% and 28.06%.

Answer:

y=2 and x=1

Step-by-step explanation:

sub 2 into 1

3(15-7y) + 4y= 11

45 - 21y +4y =11

-21y+4y= 11-45

-17y= - 34

y=2

Therefore sub y into x equation

x=15-7(2)

x= 1

Answer:

3x + 4y = 11

x = 15 -7 y

3 (15-7y) = 11

45 - 21y + 4y = 11

45 - 17 y = 11

-17 y =11 -45

-17y ÷ -17 = -34 ÷ -17

y = 2

x = 15 - 7y

x = 15 - 7(2)

x = 15 - 14

x = 1

there for y = 2 and x = 1 is the solution

Step-by-step explanation:

Answer:

right 6

down 3

Step-by-step explanation:

Take 1 point and make it go from red to blue. All the rest will do the same thing.

This is just an random choice. Choose the lowest point on the red. It is at

(-3, - 2)

Now to go to the lowest point on the blue, you start by going right from - 3 to + 3 That is 6 units to the right.

Now it also goes down. The red point is -2 for the y or down direction.

It goes down to - 5. So that's down 3 units.
