A true or false test has 5 questions. what is the probability of guessing the correct answers to all the questions?

Answers

Answer 1

Answer:

C) [tex]\frac{1}{32}[/tex]

Step-by-step explanation:

There are only two options: right or wrong.

Right for each question: [tex]\frac{1}{2}[/tex]

Since there are 5 questions, and 5 right answers are desired: [tex]\frac{1}{2} * \frac{1}{2} * \frac{1}{2} * \frac{1}{2} * \frac{1}{2}[/tex]

= [tex]\frac{1}{32}[/tex]

This year, Ms. Makratzaki’s small hardware store had sales of $536,000. Five years ago, the store had $441,000 in sales, and last year it had $517,000 in sales. Assuming a constant rate of increase, predict the amount of sales the store will have after 8 years.

a.

$650,000

b.

$669,000

c.

$688,000

d.

$707,000



Please select the best answer from the choices provided


A

B

C

D

Answers

Answer = 688 thousand / 688,000

Explanation - 536-517 = 19 so 19000 x 8 + 536000 = 688,000

Thinking it as a propotional increase, find the unit rate of change.

values: (0, 536,000), (-5, 441,000), (-1, 517,000)

unit rate of change:

[tex]\sf \dfrac{y2-y1}{x2-x1}[/tex]

[tex]\dashrightarrow \sf \dfrac{536,000-441,000}{0-(-5)}[/tex]

[tex]\dashrightarrow \sf 19000[/tex]

Therefore, the sales increase by $19000 each year.

After 8 years the sale increasement:

$19000 * 8$152000

Total sales amount:

current sales + increasement in sales$536,000 + $152000$688,000

So, correct answer is : $688,000

Answers

Answer:

111-(9*12)=3.

Step-by-step explanation:

There are 111 ounces of orange paint, which is going to go into the other bottles. How many bottles? 9. However, because in life we have different sized bottles, it states each bottle takes 12 ounces. In order to find the amount of ounces needed to find all 9 bottles, we first multiply 9*12, which equals 108. Filling all the bottles with orange paint will take up 108 ounces of the orange paint. We do have enough, since we have 111 ounces, but we must find how many ounces we have now that we've used up 108, which can be done by subtraction. 111-108=3. We have 3 ounces left over.

Now we translate everything we did into a mathematical equation. First, we multiplied, and then we subtracted the product from 111. 111-(9*12), which equaled 3, so 111-(9*12)=3. The parentheses technically aren't necessary, because if this is solved according to PEMDAS (the order of operations), the multiplication will occur first anyway.

1. What are the perimeter and area of a rectangle with a length of 20 in. and a width of 15 in.? (1 point)
P = 35 in., A = 300 in.2
P = 70 in., A = 300 in.2
P = 300 in., A = 70 in.2
P = 35 in., A = 200 in.2

Answers

Answer:

It's the 2nd one

Step-by-step explanation:

So to find the perimeter you add all the sides together. So if 2 of the sides are 20 and 15, that means the other ones are 20 and 15.

Once you add those all together you get 70.

To find the area you multiply the two different sides, so that would be 20 and 15.

20 times 15 is 300.

Answers

Answer

The width is 3.56

Step-by-step explanation:

Area=length × width

The area is 16.02

The length is 4.5

The width is unknown so we are going to call it X

4.5X=16.02

divide 16.02/4.5 = 3.56

Answer:

3.56 meters

The formula for area of a square is length * width = area

So divide the length from the area to found out our width

16.02 / 4.5 = 3.56
