Answer:

5<x<21

Step-by-step explanation:

when any two sides are added together they have to be greater than either side... to find the range

add the two sides together to get the upper end of the range 8+13=21

and to get the lower end of the range subtract 13-8=5

so the range is 5<x<21

the third side CAN NOT be 5 or 21, must be between them

I = a + (n - 1)d [Given formula]

Find d when I = 10, a = 2, n = 5

I = a + (n - 1)d [Given]

Putting the value of I = 10, a = 2, n = 5 we get,

10 = 2 + (5 - 1)d

10 = 2 + 4d

10 - 2 = 4d

8 = 4d

d = [tex] \frac{8}{4} [/tex]

d = 2

Answer:

m = -4/5

Step-by-step explanation:

We need to find the slope of the line that passes through the points (3, 1) and (-2,5).

The slope of the line is given by :

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Put x₁ = 3, x₂ = -2, y₁ = 1 and y₂ = 5

Put all the values,

[tex]m=\dfrac{5-1}{-2-3}\\\\=\dfrac{4}{-5}\\\\=\dfrac{-4}{5}[/tex]

So, the correct option is (b).

Answer:

At 5% level of significance the conclusion of the test is that the number of intervals used to test the hypothesis is : 5

Step-by-step explanation:

At 5% level of significance the conclusion of the test is that the number of intervals used to test the hypothesis is : 5

since each interval contains equal number of values lets divide the data into 6 groups i.e.  frequency in the third group = 30 /6 = 5

hence we can say that the number of intervals used to test the hypothesis is 5

Answer:

it has 6 faces

Step-by-step explanation:

A rectangular prism has 6 flat surfaces.

A rectangular prism is a polyhedron with two congruent and parallel bases.

Another name for a rectangular prism is cuboid.

A rectangular prism has 6 faces, 8 vertices and 12 edges.

Flat surface are called plane.

We see that a rectangular prism has six sides and all of its sides are rectangles.

Therefore, all the sides of a rectangular prism are flat surfaces. Since a rectangular prism has six sides; it has six flat surfaces.

The diagram is a rectangular prism.

Step-by-step explanation:

The volume of the square pyramid is 405 cubic inches.

The correct answer is option (B).

V = 1/3 × base area × h,

where h is the height of the pyramid.

P = 4 × a

where, 'a' represents the side of the square

For given example,

Let 'a' be the side length of the square base.

We have been given the perimeter of the square base is 36.

⇒ P = 36

⇒ 4 × a = 36

⇒ a = 9

So, the length of the side of the square base is 9 in.

Using the formula of the volume of the pyramid,

⇒ V = (1/3) × base area × h

⇒ V = (1/3) × a² × h

⇒ V = (1/3) × (9)² × 15

⇒ V = 27 × 15

⇒ V = 405 cubic inches

Therefore, the volume of the square pyramid is 405 cubic inches.

The correct answer is option (B).

Answer:

908

Step-by-step explanation:

Answer:

908

Step-by-step explanation:

Answer:

88 half gallons

Step-by-step explanation:

We can solve this problem by creating an equation. First we will need a variable. Since we are trying to find how many half gallons the store bought, that will be what our variable represents.

Let g = the number of half gallons

Since the store bought milk for $2.60 per half gallon, the amount of money they spent will be 2.6g.

The remaining milk is sold for $4.08 per half gallon. Remember, the store lost 15 half gallons so the number of gallons is currently g-15. This means that to find the amount of profit they made, we use 4.08(g-15).

We already know that the profit is $69.04, so we can make this into an equation.

This profit is the amount of money made minus the cost.

4.08(g-15) - 2.6g = 69.04

We can begin to solve this by simplifying the left side.

4.08(g-15) - 2.6g

4.08g - 61.2 - 2.6g

1.48g - 61.2

This makes our new equation:

1.48g - 61.2 = 69.04

We can begin to isolate our variable, g, by adding 61.2 to both sides.

1.48g = 130.24

Then we divide both sides by 1.48.

g = 88

D - 1,078

Step-by-step explanation:

if you take 26.96 x 40, you will get 1,078

Answer:

A) 0.0088

B) 0.2997

C) 5

Step-by-step explanation:

Given: Mean: Ч = 79 minutes

Standard deviation : б = 8 minutes

The formula for z score:

z= x-ц/σ

a) For x=60 minutes

z= 60-79/8 = -2.375

The p-value = P(z< -2.375) = 0.0087745 ≈ 0.0088

b) For x= 75 minutes

z= 75-79/8 = -0.5

The p-value = P(60 < x < 75) = P (-2.375 < z < -0.5)

= P(-0.5)-P(-2.375)= 0.3085 -0.0088 =0.2997

c) For x=90 minutes

z= 90-79/8 = 1.375

The p-value = P (z > 1.375)= 1-P(z < 1.375)

= 1-0.9154342 = 0.0845658

If the number of students in the class=60.

Then, the number of students will be unable to complete the exam in the alotted time = 0.0845658 x 60 = 5.073948 ≈ 5

Answer:

  (x, y) = (2, -2)

Step-by-step explanation:

We would normally choose to use substitution when x or y could be easily solved-for without having fractions involved. That is not the case here. However, we observe that the term 3y appears in both equations, so we can substitute for "3y" instead of "y".

From the second equation, ...

  3y = 5x -16

Substituting into the first equation, ...

  2x +(5x -16) = -2

  7x = 14 . . . . . . . . . add 16

  x = 2 . . . . . . . . . .  divide by 7

Using our equation for y, we get ...

  3y = 5(2) -16 = -6

  y = -2 . . . . . . . . . divide by 3

The solution is (x, y) = (2, -2).

[tex]210^\circ = \frac{7}{6}\pi[/tex]

Step-by-step explanation:

Given

[tex]\theta = 210^\circ[/tex]

Required

Convert to radians

To convert to radians, we make use of:

[tex]Radians = \theta * \frac{\pi}{180^\circ}[/tex]

Substitute: [tex]\theta = 210^\circ[/tex]

[tex]Radians = 210^\circ* \frac{\pi}{180^\circ}[/tex]

[tex]Radians = \frac{210^\circ* \pi}{180^\circ}[/tex]

Simplify fraction

[tex]Radians = \frac{7\pi}{6}[/tex]

[tex]Radians = \frac{7}{6}\pi[/tex]

Hence:

[tex]210^\circ = \frac{7}{6}\pi[/tex]

It is not possible for a cross section of a cylinder to have a triangular shape

Cross section is the non-empty intersection of a solid body in three-dimensional space with a plane, or the analog in higher-dimensional spaces

A cylinder has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes

A triangle is a shape formed when three straight lines meet

Cross section of the cylinder is depends on how we cut .The cross-section of a cylinder may be either circle, rectangle, or oval
