A student took 5 test in a quarter 3. His average was a 88. Four of his test scores were 87, 94, 86, and 100. What was his last test score? ( statistics) ( please write down or type it out! ) ty

Answers

Answer 1

Answer:

The last test score should be 73

Step-by-step explanation:

[tex]88 = \frac{( 87 + 94 + 86 + 100 + X )}{5}[/tex]  

Add all the values in the parentheses together to get:

[tex]88 = \frac{367 + X}{5}[/tex]

You want to remove the 5 next, so you multiply both sides by 5.

[tex]5 * 88 = \frac{367 + x}{5} *5[/tex]

[tex]88 * 5 = 440[/tex]

You should get:

[tex]440 = 367 + x[/tex]

The last step is to subtract both sides by 367:

[tex]440 - 367 = 73[/tex]

[tex]X = 73[/tex]

I hope this helps!

A box of oranges has a mass of 4 kg. If one orange is 80 g, how many oranges are in the box?

Answers

Total mass of box = 4 kg or 4000 grams

Number of oranges= 4000/80

= 50 oranges

Answer:

50 oranges are in the box

Step-by-step explanation:

First, find the converting of 1 kg to grams (1kg = 1000g)

Then, convert how many kg is the box of oranges (4kg = 4000g)

Finally, divide the total grams of the box by the total grams per EACH orange in the box (4000g ÷ 80g = 50)

Therefore, there are 50 oranges in the box

Find the surface area of the triangular prism (above) using its net (below).

Answers

This is quite simple, first, you must find the area of each shape, since the form of the prism is currently 2D.

Formula for (Area of Rectangle)= length x width

Formula for (Area of Triangle)= 1/2 base x height

Now, we have the formulas. Let’s get started!

(Identification) There are 3 rectangles and 2 triangles. 2 rectangles are of the same size and 2 triangles are of the same size.

Triangles~ the base is 6 and the height is 4.

1/2 (6 x 4) = 12

However, there’s two triangles. (of the same size)

12 x 2 = 24

Rectangles 1 and 2~ the length is 5 and the width is 7

5 x 7 = 35

However, there’s two rectangles. (of the same size)

35 x 2 = 70

Rectangle 3~ the length is 6 and the width is 7

6 x 7 = 42

There’s only one of these.

Now we add all the areas of the shapes together!

24 + 70 + 42 = 136

The surface area is 136.

The cost of a cleaning service includes labor and supplies. Supplies are 30% of the total cost. The cost of supplies for a certain cleaning service is $54.

What is the total cost of the cleaning service?

Enter your answer in the box.

$

Answers

Answer:

180

Step-by-step explanation:

If supplies cost 54$ and thats 30% of the total cost, that means you would divide 54 by 3 and that would be 18. Then you would times 18 by 10 to get your final answer: 180$. The reason you would times 18 by 10 is because 18 is 10% percent of 100% and 10 times 10 is 100.

The answer is 80 because if you multiply 100 by 54 you get 5400 and you divide 30 to get 180 so the total cost is 180

The circumference of a circle is 50.24 meters.

What is the diameter, in meters? Use 3.14 for π and round to the nearest meter, if necessary.

Answers

hey there!

We know that ,

Circumference is a circle = 2 pi r

=> 2 pi r = 50.24

=> r = 50.24/2 x 3.14

=> r = 78.8 m

But to find diameter , d = 2 x radius => 2 x 78.8 = 157.73 which is approximately 158

Option d is correct
diameter=16

circumference=radius*2*3.14
50.24=r*2*3.14

1. divide 50.24 by 2
2. divide that answer by 3.14
3. this leaves you with the radius. multiply by 2 for the diameter

Revising the area of a circle formula

We already know that the area of a circle is expressed as [tex]\pi r^{2}[/tex].

The "r" variable is known as the radius.Solving each problem given:Solving Problem 4:

We are given the radius of circle, which is 7 in. Let us substitute the radius in the formula. Once substituted, we can simplify the expression obtained to determine the area of the circle shown in the picture.

[tex]\implies \pi (7)^{2}[/tex]

Take π as 22/7

[tex]\implies \huge\text{(}\dfrac{22}{7} \huge\text{)}(7)^{2}[/tex]

[tex]\implies \huge\text{(}\dfrac{22}{7} \huge\text{)}(7)(7)[/tex]

[tex]\implies (22)(7)[/tex]

[tex]\implies 154 \ \text{in}^{2}[/tex]

Solving Problem 5:

In this problem, we are given the diameter to be 24 kilometers. Since the radius of the circle is half the diameter, we can tell that the radius of the circle is 24/2 kilometers, which is 12 kilometers.

[tex]\implies \pi (12)^{2}[/tex]

Take π as 22/7

[tex]\implies \huge\text{(}\dfrac{22}{7}\huge\text{)} (12)^{2}[/tex]

[tex]\implies \huge\text{(}\dfrac{22}{7}\huge\text{)} (12)(12)[/tex]

[tex]\implies \dfrac{3168}{7} \ \text{km}^{2}[/tex]

Solving Problem 6:

We are given the radius of circle, which is 3.5 in. Let us substitute the radius in the formula. Once substituted, we can simplify the expression obtained to determine the area of the circle shown in the picture.

[tex]\implies \pi (3.5)^{2}[/tex]

Take π as 22/7

[tex]\implies \huge\text{(}\dfrac{22}{7}\huge\text{)} (3.5)^{2}[/tex]

[tex]\implies \huge\text{(}\dfrac{22}{7}\huge\text{)} (3.5)(3.5)[/tex]

[tex]\implies \huge\text{(}\dfrac{22}{2}\huge\text{)} (3.5) = (11) (3.5)[/tex]

[tex]\implies 38.5 \ \text{m}^{2}[/tex]

Note: The radius given in this problem was not clearly stated. If the radius I stated here, is incorrect, please notify me in the comments. Thanks!

His address has since become popularly known as the Four Freedoms Speech.Just as our national policy in internal affairs has been based upon a decent respect for the rights and the dignity of all our fellow men within our gates, so our national policy in foreign affairs has been based on a decent respect for the rights and dignity of all nations, large and small.

Our national policy is this:First, by an impressive expression of the public will and without regard to partisanship, we are committed to all-inclusive national defense.Second, by an impressive expression of the public will and without regard to partisanship, we are committed to full support of all those resolute peoples, everywhere, who are resisting aggression and are thereby keeping war away from our Hemisphere. By this support, we express our determination that the democratic cause shall prevail; and we strengthen the defense and the security of our own nation.Third, by an impressive expression of the public will and without regard to partisanship, we are committed to the proposition that principles of morality and considerations for our own security will never permit us to acquiesce in a peace dictated by aggressors and sponsored by appeasers. We know that enduring peace cannot be bought at the cost of other people's freedom. . . .
