[tex]\frac{x^{2} + 19x + 102}{4(x + 5)(x + 7)}[/tex]

Step-by-step explanation:

I have factored and multiplied lwh to get the volumes

Vol. = [tex]\frac{2x - 1}{(2x - 3)(x + 5)}[/tex] [tex]\frac{2(2x - 3)}{3x - 1}[/tex][tex]\frac{(3x - 1)(x + 3)}{(2x - 1)(x + 3)}[/tex] + [tex]\frac{x - 5}{3x + 2}[/tex][tex]\frac{3x + 2}{4}[/tex][tex]\frac{x - 2}{(x + 7)(x - 5)}[/tex]

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

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]

Identify the lateral area and surface area of a right cone with radius 7 cm and slant height 15 cm.

Step-by-step explanation:

Lateral area = [tex]\pi (7)(15) = 105\pi = 329.7\\[/tex]

Surface area = lateral area + base area

Base area= [tex]\pi r^{2}[/tex] = [tex]\pi (7)^{2}[/tex] = [tex]49\pi[/tex]

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 ) )

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.

  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
