The regular price of a sweater is $40, the sale price is $34. What is the percent of decrease?

Answer:

A sample size greater than 30

Step-by-step explanation: The central limit theorem proffers the conditions necessary to obtain a normal or bell shaped distribution. It defines normal distribution in terms of mean, standard deviation and sample size. The sample size is a very important factor in determining the shape of a distribution.

Thus with a population having mean and standard deviation stated, in other to make use of or assume normal distribution, the sample size must be large. According tho the central limit theorem, a size of greater than 30 is deemed to be large enough. As the Same size increases, the sample mean converges to the value of the population mean.

Answer:

The length of hypotenuse is 45 kilometers

Step-by-step explanation:

Assuming that given lengths are of perpendicular and hypotenuse, and the triangle is a right angled triangle

Perpendicular = P = 27 km

Base = B = 36 km

Hypotenuse = H = ?

We can use Pythagoras theorem for finding the length of hypotenuse

The Pythagoras theorem is given by:

[tex]H^2 = B^2+P^2[/tex]

Putting the values, we get

[tex]H^2 = (36)^2 + (27)^2\\H^2 = 1296 + 729\\H^2 =2025[/tex]

Taking square root on both sides

[tex]\sqrt{H^2} =\sqrt{2025}\\H =45[/tex]

Hence,

The length of hypotenuse is 45 kilometers

Step-by-step explanation:

so we have

8 men.........................................9 women

40 men.......................................45 women

there are 40 men in the recital

45/9=5

5*8=40 men

Answer:

[C] 52

Step-by-step explanation:

If line SQ bisects angle RST, that means it splits it in half. This would make angles RSQ and QST equivalent.

So that means that angle RSQ would equal 26

Since the question is asking for angle RST (the whole angle), you would add both of the angles

26 +26 = 52

Answer:

14 feet

Step-by-step explanation:

We solve the above question by using the Greatest Common Factor method

We find the factors of 56 and 98

The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56

The factors of 98 are: 1, 2, 7, 14, 49, 98

Then the greatest common factor is 14.

Therefore, the greatest possible length you can cut the rope so all pieces will be the same is 14 feet

Step-by-step explanation:

1. Increase amount = 40-25=15 Increase percent = (15/25)×100%= 60%.

2.Increase amount = 30-15 = 15. Increase percent = ( 15/15)× 100% = 100%.

3. Increase amount= 50-18=32 Increase percent= (32/18) x100% = 177.77%

4. Increase amount= 80-22=58 Increase percent= (58/80) x 100% = 72.5% -----> 73% (when rounded of to the nearest 10's).

5. Increase amount= 18-16=2 Increase percent = (2/18)×100 %= 11.111...% -----> 11% (when rounded of to the nearest 10's).

6. Increase amount = 10-3=7 Increase percent= (7/10)×100% = 70%.

7. Increase amount = 100-85 = 15 Increase percent = ( 15/100) × 100% = 15%

Answer:

30%

Step-by-step explanation:

Key skills needed: Probability

1) There is a 70% chance of rain.

2) We need to find the chances against rain.

3) To do this, we need to use the fact that

70% + x = 100% (Since all the probabilities add up to 1 or 100%)

4) If you subtract 70% from both sides, x = 30%

5) This means the probability against rain is 30%.

Hope you understood and have a nice day!! :D

Answer:

They can run 32 times down the court

Step-by-step explanation:

Answer:

2 1/5

2 X 5 + 1 = 11/5

11/5 X 2/1 = 22/5

1 3/4

1 X 4 + 3 = 7/4

7/4 X 2/1 = 14/4

22/5 + 14/4

5 X 4 = 20

4 X 22 = 88

5 X 14 = 70

88/20 + 70/20 = 158/20

20 goes into 158 7 times with 18 left over

7 18/20 simplified = 7 9/10
