A right triangle has a hypotenuse of length 13 in. and a leg with length 4 in. What is the length of the other leg?

Answers

Answer 1

Answer:

Solution,

Let the hypotenuse of the right triangle be 'a' and its legs be 'b' and 'c'.

Here, a= 13, b = 4 and c=?

Using Pythagoras or Gogou theorem,

a² = b² +c²

or, 13² = 4² +c²

or, c² =153

or, c = 3√17 inch

Patty's Pavers has determined that a paver measuring 5 inches long has a z-score of +1 and a paver measuring 5.25 inches long has a z-score of +2.

Hi! I need Help!
What is the mean length of the pavers produced at Patty's Pavers?

4.25 inches
5.25 inches
4.75 inches
5.75 inches

Thank you!

Answers

Answer:

4.75

Step-by-step explanation: given x=5 inches Z-score =1 let 'X' be the variable in normal distribution z=+1 when x=5 inches.

The mean length of the pavers produced at Patty's Pavers is 4.75 inches. Thus, the correct option is C.

What is Z-score?

A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,

[tex]Z = \dfrac{X- \mu}{\sigma}[/tex]

Where Z is the Z-score,

X is the data point,

μ is the mean and σ is the standard variable.

The Z-score of +1 is,

(x-μ)/σ = 1

(5-μ)/σ = 1

5 - μ = σ

The Z-score of +2 is,

(5.25-μ)/σ = 2

(5.25 - μ)/σ = 2

5.25 - μ = 2σ

Substitute the value of the 'σ', therefore, standard deviation from the above,

5.25 - μ = 2(5 - μ)

5.25 - μ = 10 - 2μ

5.25 - 10 = -2μ + μ

μ = 4.75

Hence, the mean length of the pavers produced at Patty's Pavers is 4.75 inches. Thus, the correct option is C.

George is putting trim around his rectangular deck, including the gate. He will need 46 feet of trim to do the entire deck. If the deck is 15 feet long, how wide is the deck?
A.
6 feet
B.
16 feet
C.
8 feet
D.
23 feet

Answers

Answer:

C: 8 feet

Step-by-step explanation:

You have to find the parameter.

To do that you add all the side lengths together.

15+15=30 now you have to subtract 30 from 46 to find how much room is left.

46-30=16 now divide your answer by 2 to get the 2 remaining sides of the deck.

Students surveyed boys and girls separately to determine which sport was enjoyed the most. After completing the boy
survey, it was determined that for every 3 boys who enjoyed soccer, 5 boys enjoyed basketball. The girl survey had a
ratio of the number of girls who enjoyed soccer to the number of girls who enjoyed basketball of 7:1. If the same
number of boys and girls were surveyed and 90 boys enjoy soccer, how many girls each sport?



Please help me and show how to solve this the best answer will get brainlesest

Answers

okay, let's go!
1. for the boys, 3 soccer is 5 basketball (in a group of 8 students).
2. for the girls, 7 soccer is 1 basketball (in a group of 8 students)
3. the question mentions 90 boys like soccer, which means we increased the number of boys surveyed 30x, since 3 times 30 is 90. now, we need to increase the girl numbers by 30 as well, giving us 210 girls who like soccer for every 30 who like basketball.
