Answer:
17.9 units is the answer
Step-by-step explanation:
points are (-7,-2) and (9,6)
Pythagorean theorem can be written as,
[tex]d=\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} \\\\d=\sqrt{9-(-7))^2 + (6-(-2))^2}\\\\d=\sqrt{(16)^2+(8)^2} \\\\d=\sqrt{256+64} \\\\d=\sqrt{320} \\\\d=17.88[/tex]
Rounding off,
d = 17.9 units

Answer:
x = 15√3
y = 30
Step-by-step explanation:
In a 30°-60°-90° "special" triangle, the ratios of side lengths are ...
1 : √3 : 2
Your diagram shows the short side is 15, so the other sides can be found by multiplying the above ratio numbers by 15.
1 : √3 : 2 = 15 : x : y = 15 : 15√3 : 30
x = 15√3
y = 30

Chile anyways so the equation to the problem is 3(x+5) =20. And all you have to do is split the (x+5) into three parts on the tape diagram and it would all equal 20.

She should add 10x to both sides
Step-by-step explanation:
Answer:
Step-by-step explanation:
x² - 10x - 2 = 0 {Add 2 to both sides}
+2 = +2
x² - 10x = 2
Now to find what to add both sides, divide the co-efficient of x by 2
10/2 = 5
Add 5² to both sides
x² - 10x + 25 = 5²
(x - 5)² = 5²
Take square root both sides,
x - 5 = ± 5
x- 5 = 5 ; x - 5 = -5
x = 5+5 ; x = -5 + 5
x = 10 ; x = 0

round the numbers to estimate the quotient. 29 1/5÷4 6/7
Answers
Answer:
29 / 5 = 5.8
Step-by-step explanation:
To round a mixed number to the nearest whole number, simply look at the fraction part.
If the fraction is more than one half, round up.
If this fraction is less than one half, round down.
In the number 29 1/5, 1/5 is LESS than one half, so we round down.
In the number 4 6/7, is 6/7 is MORE than one half, so we round up.
29 1/5 rounded to the nearest whole number is 29.
4 6/7 rounded to the nearest whole number is 7.
And, 29/7 = 5.8
Therefore, the estimated quotient is 5.8.
A shoe store orders shoes from the manufacturer and sells them at a mall. Storing shoes at the store costs $6 per shoe pair for a year. When reordering shoes from the manufacturer, there is a fixed cost of $30 per order as well as $6 per shoe pair. The retail store sells 2500 shoe pairs each year. Find a function that models the total inventory costs as a function of x x the number of shoe pairs in each order from the manufacturer.
Answers
Answer:
$ ( 3 x + 75000 / x )
Step-by-step explanation:
Function that models the total inventory cost as a function of x
holding cost = $6
ordering cost ( fixed cost ) = $30
cost of a pair = $6
Total demand = 2500
∴The total inventory cost ( TIC ) is represented as
holding cost + Ordering cost
= 1 / 2 ( x ) ($6 ) + 2500 / x ( $30 )
= $ ( 3 x + 75000 / x )
while total cost = $ ( 3x + 75000 /x + ( 2500 * 6 ) )

A cylindrical fuel storage tank has a diameter of 19 feet. Determine the capacity of the tank, if its height is 34 feet. (use = 3.14)
Answers
Answer:
The tank capacity is 9,635.09 square feet.
Step-by-step explanation:
Given that a cylindrical fuel storage tank has a diameter of 19 feet and a height of 34 feet, the following calculation must be performed to determine the capacity of the tank, knowing that the volume of a cylinder arises from the following formula = π x r² xh:
Radius = 1/2 diameter
3.14 x (19/2) ² x 34 = X
3.14 x 9.5² x 34 = X
3.14 x 90.25 x 34 = X
3.14 x 3,068.5 = X
9,635.09 = X
Therefore, the tank capacity is 9,635.09 square feet.

Simple Random Sample of Size 25:
Chances are, since you are studying AP Statistics, you plan to earn at least a bachelor's degree from college. According to the U.S. Census Bureau, 29% of Americans age 25 years or older have already earned a bachelor's or more advanced degree. You decide to randomly select 58 adults over the age of 25 to ask if they have earned at least a bachelor's degree. Describe the sampling distribution of the proportion of respondents who have earned at least a bachelor's degree.
Answers
Answer:
By the Central Limit Theorem, it is approximately normal with mean 0.29 and standard deviation 0.0596
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
According to the U.S. Census Bureau, 29% of Americans age 25 years or older have already earned a bachelor's or more advanced degree.
This means that [tex]p = 0.29[/tex]
You decide to randomly select 58 adults over the age of 25 to ask if they have earned at least a bachelor's degree.
This means that [tex]n = 58[/tex]
Describe the sampling distribution of the proportion of respondents who have earned at least a bachelor's degree.
By the Central Limit Theorem, it is approximately normal with mean [tex]\mu = p = 0.29[/tex] and the standard deviation is [tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.29*0.71}{58}} = 0.0596[/tex]
