Answer:
The combination 9 mm, 6mm, 5mm will not form a triangle.
9 +6 = 15 > 5
6+5= 11 < 9
9+5 =14 > 6
Explanation :
because the side length of triangle does not obey triangle inequality theorem.
The triangle inequality theorem:
The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

So i was literally over here trying to big brain this problem, literally stressing like "Oh my gosh why is this so difficult wth is going on rn?!" when all i had to do was find the equation(which has been sitting on my paper for the last 15 minutes) and plug it in.
-_-
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.

A study was conducted to measure the effectiveness of hypnotism in reducing pain. The measurements are centimeters on a pain scale before and after hypnosis. Assume that the paired sample data are simple random samples and that the differences have a distribution that is approximately normal. Construct a 95% confidence interval for the mean of the "before−after" differences. Does hypnotism appear to be effective in reducing pain? In this example, μd is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the difference in the measurements in centimeters on a pain scale before and after hypnosis. What is the P-value for this hypothesis test? (Round to three decimal places as needed.) Answer
Required data:
Before 6.4 2.6 7.7 10.5 11.7 5.8 4.3 2.8
After 6.7 2.4 7.4 8.1 8.6 6.4 3.9 2.7
Answer:
Confidence interval = (-0.404 ; 1.804)
Pvalue = 0.178
Step-by-step explanation:
H0: μd = 0
H1 : μd ≠ 0
Difference, d = (x - y)
d = - 0.3, 0.2, 0.3, 2.4, 3.1, - 0.6, 0.4, 0.1
Using calculator :
μd = 0.7
Sd = 1.32
Confidence interval :
Mean ± margin of error
Margin of Error =Tcritical * Sd/√n
Tcritical at df = 7, 0.5, 2 - tailed = 2.365
Margin of Error = 2.365 * 1.32/√8
Margin of Error = 1.104
Lower boundary :
(0.7 - 1.104) = - 0.404
Upper boundary :
(0.7 + 1.104) = 1.804
(-0.404 ; 1.804)
Test statistic, = μd / (Sd ÷ √n)
Test statistic = 0.7 / (1.32 ÷ √8)
Test statistic = 1.499
From the test statistic score ; using a Pvalue calculator :
Pvalue = 0.178 ( 3 decimal places)
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.
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 researcher has developed an algorithm for analyzing documents. To test the performance he runs the algorithm on documents with lengths of 10 pages, 20 pages, and 30 pages. The run times were 0.1 seconds, 0.2 seconds, and 0.4 seconds. Would the algorithm be reasonable for analyzing a 300 page document? Explain.
Answer:
There are at least two reasons to articulate assumptions underlying a research problem. First, these assumptions will guide the selection of research questions and/or the formation of hypotheses, as well as the interpretation of the data. Clearly stating the assumptions assists the reader in evaluating the merits of the study and the conclusions drawn from it. Second, to the extent that the researcher is aware of his/her assumptions, these can be incorporated into the study design as needed to promote the validity of the conclusions drawn from the study.

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.
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]

Answer:
see explanation
Step-by-step explanation:
Equate the values on the left to like values on the right side
4
4x + 2i = 8 + yi , then
4x = 8 ⇒ x = 2
y = 2
Then x = 2, y = 2
5
- 10x + 12i = 20 + 3yi , then
- 10x = 20 ⇒ x = - 2
3y = 12 ⇒ y = 4
Then x = - 2, y = 4
6
2x - yi = 14 + 12i , then
2x = 14 ⇒ x = 7
- y = 12 ⇒ y = - 12
Then x = 7, y = - 12
7
54 - [tex]\frac{1}{7}[/tex] yi = 9x - 4i , then
9x = 54 ⇒ x = 6
- [tex]\frac{1}{7}[/tex] y = - 4 ( multiply both sides by - 7 )
y = 28
Then x = 6, y = 28
Answer:
4x + 2i = 8 + yi , then
4x = 8 ⇒ x = 2
y = 2
Then x = 2, y = 2

Step-by-step explanation:
The height of a toy rocket launched from 64 foot observation tower function of elapsed time since the launch is modeled in the equation below h(t)=-16t^2+48t+64 at  what approximate elapsed time (s) will the toy rocket be at a height of 90 feet?
Answer:
0,70 s
Step-by-step explanation:
We have to solve the associated equation:
-16t^2 + 48t + 64 = 90
1) divide each member by 2
-8t^2 + 24t + 32 = 45
2) add at both member -45
-8t^2 + 24t + 32 -45 = 45-45
-8t^2 + 24t - 13 = 0
3). multiply the two members by -1
8t^2 - 24t + 13 = 0
4) find Δ/4 with the reduce formula
Δ/4 = 144 -104 = 40
5) find the approximate solutions with the reduce formula
t1 = (12 + 6,42)/8 = 2,29 s
t2 = (12 - 6,42)/8 = 0,70 s
we have to take the smallest value because the biggest describe when the rocket will reach 90 feet when it is descending

1/8 plus 3/4: plz tell me I need help
Answer:
7/8
Step-by-step explanation:
Find the common denominator:
4 and 8 are both the least common multiple of 8.
So that would be the common denominator.
To get 3/4 to become a fraction of 8, you would multiply both 3 and 4 by 2.
[tex]\frac{1}{8} + \frac{3}{4} = \frac{1}{8} + \frac{6}{8} = \frac{7}{8}[/tex]
round the numbers to estimate the quotient. 29 1/5÷4 6/7
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.
