Answer 1

Answer:

18 is .20

19 is c+5 over 3

Step-by-step explanation:

18.

p= 4C 1 /4C1 * 5C1 = 4 / 4*5 = .20

19.

(3a - 5) / c = 1

3a - 5 = c

3a = c + 5

a = (c + 5) / 3

Answer 2
#18 is B because 4/20 possibilities add up to ten.
#19 is C because the bs cancel out and you get 3a-5=c -> 3a=c+5 -> a= (c+5)/3

help i forgot how to do this and this is one of the last questions on my summer homework

Answers

Answer:

162°

Step-by-step explanation:

They are on a straight line so add to 180

8x + 10 + 2x - 20 = 180

10x - 10 = 180

10x = 190

x = 19

We want AXB so 8x + 10 where x = 19

8(19) + 10 = 162 so it is 162°

Answer:

162 degrees

Step-by-step explanation:

These two angles add up to 180.

8x + 10 + 2x - 20 =180  Next combine the x terms and the constant terms

10x -10 = 180   Next Add 10 to both sides

10x = 190  D  Next divide both sides by 10

x = 19.  Now that we know x, we can solve for <AXB

8x + 10

8(19) + 10

152 + 10 = 162

How are the pieces of a step function related to the domain of the function? Justify your thinking.

Answers

Step-by-step explanation:

As we know, for any function domain is referred to as the set of input values that can be taken for an independent variable in the given function. Range of a function is defined as the set of output values generated for the domain (input values) of the function. In the case of a step function, for each value of x, f(x) takes the value of the greatest integer, less than or equal to x. For example:

[-2.19] = -3

[3.67] = 3

[-0.83] = -1

The domain of this function is a group of real numbers that are divided into intervals such as [-5, 3), [-4, 2), [-3, 1), [-2, 0) and so on. This explains the domain and range relations of a step function.

This can be generalized as given below:

[x] = -2, -2 ≤ x < -1

[x] = -1, -1 ≤ x < 0

[x] = 0, 0 ≤ x < 1

[x] = 1, 1 ≤ x < 2

As we know, for any function domain is referred to as the set of input values that can be taken for an independent variable in the given function. Range of a function is defined as the set of output values generated for the domain (input values) of the function. In the case of a step function, for each value of x, f(x) takes the value of the greatest integer, less than or equal to x.
For example:
1-2.191 =-3
13.671 = 3
[-0.831 = -1
The domain of this function is a group of real numbers that are divided into intervals such as [-5, 3), [-4, 2), [-3, 1), [-2, 0) and so on.
This explains the domain and range relations of a step function.

What was the experimental probability that the tack lands point-up for student 7?

0.800

0.833

0.200

Answers

Answer:

0.833

Step-by-step explanation:

1. locate which vertical column of the graph we are referring to:

student 7

2. calculate the total number of trials student 7 did:

if in 5 trials the tack landed point-up, and in 1 trial the tack did not land point-up, the total number of trials is 65 + 1 = 6

3. refer back to the question:

the question states: "what is the experimental probability that the tack lands point-up"

4. interpret the graph:

of the 6 trials student 7 underwent, the graph tells us that 5 landed point-up. therefore the experimental probability of a tack landing point up is 5/6 (in 5 out of the 6 trials, the tack landed point-up)

5. converting from fraction to decimal:

all the given answers are given in decimal form, whilst our current answer (5/6) is in fraction form. to convert to decimal form, simply divide the top number by the bottom number5 ÷ 6 = 0.833

therefore, the experimental probability that the tack will land point-up, is 0.833

Ben is picking cherries to make jam. each cherry weighs about 1/2 ounce. There are 16 ounces in a pound. He needs 3 pounds of cherries. About how many cherries does he need to pick?

Answers

Solve by doing everything backwards. If he needs 3 ounces, and there is 16 ounces in a pound, that is 48 ounces of cherries needed. Since each cherry is about 1/2 a pound, double the 48. You end up with 96 and that is your answer.


96 cherries

Answer:

96 Cherries

Step-by-step explanation:

This is a question on some unit conversions.

First we convert 3 pounds to ounces.

Given 16 ounces = 1 pound,

3 pounds = 3 x 16 ounces = 48 ounces

Next, we will find the number of cherries required.

Number of Cherries required = Total weight of cherries needed (in ounces) / Weight per cherry.

= [tex]\frac{48}{0.5}[/tex]

= 48 * 2

= 96 cherries

Answers

Answer:

184m^2

Step-by-step explanation:

Ok first we will look at the triangles.

The formula for triangles is 1/2bh

The base in our triangle is 6, and the height is 4. Also, we have 2 such triangles.

so, we need to plug in our values into our formula, and multiply it by 2, since there are 2 triangles.

2( 1 / 2 ( 6 ) ( 4 ) )

2 ( 12 )

24.

The area of the 2 triangles is 24.

Now, the next part is gonna be hard to explain, but I promise the final answer is right.

lets find the area of the rectangle in the middle. That's easy, 6*10 = 60.

Because the top rectangle would connect to the 5m side of the triangle, then the area of the rectangle would be 10*5 = 50

The same thing applies to the bottom rectangle, so its also 50.

24+50+50+60 = 184

The unit is meters(m)

So, 184 m^2

The surface area of the prism based on the net provided will be 184 square meters.

What is the surface area of a triangular prism?

Let h be the height and b be the base of the triangle.

Let L₁, L₂, and L₃ be the length and W be the width of the rectangle.

Then the surface area of the triangular prism will be

Surface area = 2 Area of triangle + 3 Area of rectangle

Surface area = h x b + (L₁ + L₂ + L₃) x W

From the figure, the length of the rectangles will be 5 m, 6 m, and 5m,  and the width is 10 m.

From the figure, the height is 4 m and the base is 6 m of the triangle. Then we have

Surface area = 4 x 6 + (6 + 5 + 5) x 10

Surface area = 24 + 16 x 10

Surface area = 24 + 160

Surface area = 184 square m

The surface area of the prism based on the net provided will be 184 square meters.

Since the question stated that all the sides are equal. (AB=BC=CD)

It also stated that the diagnonals are equal. (AC=BD=AD)

I wish I could draw to explain this easily

A square has four right angles.

A right angle is a 90⁰ angle.

The diagonals divide each 90⁰ angle by 2

I hope you know what a diagonal is.

It is a line from a corner of the square to the opposite corner. This cuts the square into two equal sides.

After drawing the first diagonal two triangles of equal size will be seen.

After drawing the second diagonal the two triangles that appeared will each be cut into halves.

Now, you'll have four equal triangles.
