Always know the formula for volume prism because that shape is a prism.

Formula For PRISM: BH/2 x Height.

So then we are going to solve the triangle first... 7 x 22= 154/2= 77

Then multiply by the height which is 25.

77 x 25= 1,925.

So your answer should be 1,925 meters cubed. *Don't forget to write the measurement

*hope this helps

Step-by-step explanation:

Answer:D x=45° y=10.9√2

Step-by-step explanation:

In a right angle were two sides are equal, two remaining angles add up to 90. So it is 90/2 which is 45°

Y²=10.9²+10.9²

Y=15.41

Or y = 10.9√2

Answer:

The expected number of keys she will try before she opens the door is 4.5.

Step-by-step explanation:

A woman has eight keys on a key ring, one of which fits the door she wants to unlock.

Each of them is equally as likely to be the one to work, which means that this situation is represented by an uniform distribution with lower bound [tex]a = 1[/tex] and upper bound [tex]b = 8[/tex].

Find the expected number of keys she will try before she opens the door.

The expected value of the uniform distribution is given by:

[tex]E = \frac{a + b}{2}[/tex]

Considering [tex]a = 1, b = 8[/tex], as is the case in this exercise:

[tex]E = \frac{1 + 8}{2} = 4.5[/tex]

The expected number of keys she will try before she opens the door is 4.5.

Answer:

  x = 0.8

Step-by-step explanation:

If you mean y = √(1 -x²), then the curves cross at x=0.8.

__

If you equate the y-expressions, then square both sides, you have ...

  √(1-x²) = 2x-1

  1 - x² = (2x -1)² = 4x² -4x +1

  0 = 5x² -4x . . . . . subtract the left-side expression

  x(5x -4) = 0   ⇒   x = 0, or x = 4/5

The x=0 solution is extraneous.

The two equations are equal at x = 4/5.

Answer:

C

Step-by-step explanation:

Answer:

To find solutions to an equation, we can choose any values for x, and then use the equation to find the value of y to make an ordered pair in the form (x,y). First, let's choose x = 1. y = 3(1) + 4 = 7 The ordered pair is (1,7) Let's choose x = 4. y = 3(4) + 4 = 16 The ordered pair is (4,16) Let's choose x = 11 y = 3(11) + 4 = 37 The ordered pair is (11,37) The three solutions we found are: (1,7) (4,16) (11,37) Note that we could choose any values for x that we like. In this case we chose x = 1, x = 4, and x = 11, but any values of x will work fine.

Answer:

0.872

Step-by-step explanation:

The regression fits the data well leavubgbiut just one of the points, this shows there is a strong relationship between the plotted variables. Also, we have to look at the direction of the regression line which will give us an idea of the slope, hence the type of correlation between the two variables (either positive or negative relationship). In this case the slope is positive and hence the correlation Coefficient will be positive as well. Hence we can say there is a strong positive relationship between the variable. The only option which depicts this association is 0.872

Answer:

It would be 25.

Step-by-step explanation:

By knowing that opposite sides of a rectangle are congruent, you can start by making a right triangle, with 7 and 24 as the legs.

Next, employ Pythagorean Theorem (a^2+b^2=c^2) to get the diagonal.

7^2+24^2=c^2

49+576=c^2

625=c^2

25 = c

It would be 25.

Step-by-step explanation:

Answer:

height: 7 in

base: 14 in

Step-by-step explanation:

Let the height of the triangle equal x. This means that the base can be represented by the expression 2x. Now we plug these values into the area formula for a triangle:

A = bh / 2

49 = x * 2x / 2

And simplify

49 = x^2

We can find the square root of both sides to get x = 7, so the height is 7 inches. Since the base is twice the height, it is 14 inches.

Answer:

[tex]h=7,\\b=14[/tex]

Step-by-step explanation:

Since the base is twice as long as the height, set up the following proportion:

[tex]b=2h[/tex].

The area of the a right triangle is equal to [tex]A=\frac{1}{2}bh[/tex], where [tex]b[/tex] is a base of the triangle and [tex]h[/tex] is the respective height.

To solve for height, set up the equation (substituing [tex]b=2h[/tex]:

[tex]\frac{1}{2}\cdot2h\cdot h=49,\\2h^2=98,\\h^2=49,\\h=\boxed{7}[/tex]

To solve for base, substitute [tex]h=7[/tex] in the proportion [tex]b=2h[/tex]:

[tex]b=2(7),\\b=\boxed{14}[/tex]

Answer:

6

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

the two lines mean absolute value.  The absolute value of a number is just the number positive. For example the absolute value of -5 is 5 and the absolute value of 5 is 5. So on C, when you plug in -6, you get the absolute value of -6 which is 6. 6 is not greater than 6

Answer:

-4.5

Step-by-step explanation:

Answer:

1.

The null hypothesis is [tex]H_0: \mu = 4[/tex]

The alternate hypothesis is [tex]H_1: \mu > 4[/tex]

2.

The p-value of the test is of 0.0045.

3.

The p-value of the test is low(< 0.01), which means that there is enough evidence that the flow rate is more than 4 gallons per minute (gpm) and thus, the pump should be put into service.

Step-by-step explanation:

A new centrifugal pump is being considered for an application involving the pumping of ammonia. The specification is that the flow rate be more than 4 gallons per minute (gpm).

At the null hypothesis, we test that the mean is 4, so:

[tex]H_0: \mu = 4[/tex]

At the alternate hypothesis, we test that the mean is more than 4, that is:

[tex]H_1: \mu > 4[/tex]

The test statistic is:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.

4 is tested at the null hypothesis:

This means that [tex]\mu = 4[/tex]

In an initial study, eight runs were made. The average flow rate was 6.4 gpm and the standard deviation was 1.9 gpm.

This means that [tex]n = 8, X = 6.4, s = 1.9[/tex]

Test statistic:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{6.4 - 4}{\frac{1.9}{\sqrt{8}}}[/tex]

[tex]t = 3.57[/tex]

P-value of the test:

The p-value of the test is the probability of finding a sample mean above 6.4, which is a right-tailed test with t = 3.57 and 8 - 1 = 7 degrees of freedom.

With the help of a calculator, the p-value of the test is of 0.0045.

3. Should the pump be put into service?

The p-value of the test is low(< 0.01), which means that there is enough evidence that the flow rate is more than 4 gallons per minute (gpm) and thus, the pump should be put into service.

In ascending order,

36, 43, 50, 51, 58, 59, 60, 69, 73

N=9

median (Q2)= N+1/2

or, Q2= 9+1/2

or, Q2= 10/2

= 5th item

Therefore, the median is 58.

Answer:

B. 273

Step-by-step explanation:

First we have to find the volume of the pencil box.

The volume formula for a rectangular prism is lwh (Length x width x height). Length (6 1/2) x Width (3 1/2) x Height (1 1/2) = 34.125 (Volume of the pencil box)

Next, we have to find the volume of the cube.

The volume formula of a cube is the same as the volume formula for a rectangular prism (lwh). However, a cube's side lengths are all the same. This means that the volume of the cube would be Length (.5) x Width (.5) x Height (.5) = .125

Last, we have to divide the volume of the pencil box by the volume of the cube.

34.125 / .125 = 273 or B.

Answer:

x = 40

Step-by-step explanation:

So a triangle is 180 degrees

and thats a right triangle = 90 degrees

you have three corners: 90, 50 & x

90 + 50 + x = 180

140 + x = 180

subtract 140 from both sides

x = 40

hope this helps

like this up !

Answer:

40 is the asnwer

Step-by-step explanation:

1. Well, first of all we know that all right angles add up to 180 degrees. The degrees shown in the picture are 50, and 90. You can’t see the 90 exactly, but you can tell by that little square, that’s how it shows us!

2. Second step, we add up 60 and 90 which is 140. We got that, now we can subtract this 140 to the 180 to get our answer!

3. 180 – 140 is equal to 40!

4. Therefore, the 3rd angle is 40!

5. Not confident with my ansawer? Proof time!

6. 40 + 50 + 90 = 180

7. Since this all adds up to 180, it is true!

Step-by-step explanation:

Answer and Step-by-step explanation:

Each unit is equal to each other, and we know that both allowances together equates to 72, so if we divide the amount of units that there are, we can determine the amount per month.

There are 8 units in total.

72 divided by 8 = 9

Now, we do 9 times the amount each person has.

You = 5 * 9 = 45

Answer:

The quantities that would be used to determine the total cost for Joey to derive to work using the highway are:

A. 0.5 hours

C. $1.25 per car

D. $3.05 per gallon

F. 35 miles per gallon

H. 54 miles per hour

Step-by-step explanation:

Cost of a gallon of gas = $3.05

Distance travelled per gallon on the highway = 35 miles

Distance travelled per gallon in the city = 27 miles

Joey's average speed using the highway = 54 miles per hour

Number of hours to get to work using the highway = 0.5 hours

Toll on the highway = $1.25

Joey's average speed using the city street route = 36 miles per hour

Number of hours to get to work using the city street route = 1 hour

Relevant data for highway driving total costs:

Cost of a gallon of gas = $3.05

Distance travelled per gallon on the highway = 35 miles

Joey's average speed using the highway = 54 miles per hour

Number of hours to get to work using the highway = 0.5 hours

Toll on the highway = $1.25

Total costs for using the highway = $1.25 + ($3.05/35 * 54 * 0.5) = $3.60
