Whats 21 square root of 98 divided by 7 square root of 21
The 21 square root of 98 divided by 7 square root of 21 = 21√98 / 7√21 = 6.4807407
A square root of a number x is a number y such that y2 = x; in other words, a number y who's square and the result of multiplying the number by itself, or y ⋅ y, is x.
Every nonnegative real number x has a unique nonnegative square root, called the principal square root, which is denoted by √where the symbol √ is called the radical sign.
Every positive number x has two square roots: √ which is positive, and -√ which is negative. The two roots can be written more concisely using the ± although the principal square root of a positive number is only one of its two square roots, the designation "the square root" is often used to refer to the principal square root.

how to find the standard deviate and variance of a discrete random variable in ap stats organic chem tutor
Calculation the variance and standard deviation of the discrete random variable is given by σ² = \(\frac{\sum\limits^n_1{(x_{i}-\bar{x}) } \,}{n-1}\) and standard deviation is the square root of Variance 'σ' = \(\sqrt{\frac{\sum\limits^n_1{(x_{i}-\bar{x}) } \,}{n-1}}\).
As given in the question,
Variance is used to represent the dispersion of the values in the data from the calculated mean.\(( x_{i} - \bar{x})\) represent the dispersion of the given data values from the mean.Variance is given by σ² = \(\frac{\sum\limits^n_1{(x_{i}-\bar{x}) } \,}{n-1}\) Standard deviation is the square root of the variance it represents the amount of dispersion of all the given data values.Standard deviation is given by 'σ' = \(\sqrt{\frac{\sum\limits^n_1{(x_{i}-\bar{x}) } \,}{n-1}}\).Therefore , the variance and standard deviation of the discrete random variable is calculated with the help of the following formulas:
Variance 'σ²' = \(\frac{\sum\limits^n_1{(x_{i}-\bar{x}) } \,}{n-1}\) and standard deviation 'σ' = \(\sqrt{\frac{\sum\limits^n_1{(x_{i}-\bar{x}) } \,}{n-1}}\).

Television networks rely heavily on ratings of television shows when deciding whether to renew a show for another season. Suppose the Hyena network has decided that Miniature Golf with the Stars will be renewed only if it can be established that more than 12% of U.S. adults watch the show. A polling company asks a random sample of 2000 U.S. adults if they watch Miniature Golf with the Stars. The network uses the data to perform a test of � 0 : � = 0.12 H 0 :p=0.12 versus � � : � > 0.12 , H a :p>0.12, where p is the true proportion of all U.S. adults who watch the show. Describe a Type I error and a Type II error in this setting.
In the context of the test performed by the Hyena network regarding the viewership of Miniature Golf with the Stars, a Type I error and a Type II error can occur.
A Type I error, also known as a false positive, would happen if the network incorrectly rejects the null hypothesis (H0) when it is actually true. In this case, it means that the network concludes that more than 12% of U.S. adults watch the show (rejecting H0: p = 0.12) when, in reality, the true proportion is not greater than 12%. This could lead to the show being renewed based on inaccurate information.
On the other hand, a Type II error, also known as a false negative, would occur if the network fails to reject the null hypothesis (H0) when it is actually false. It means that the network concludes that the proportion of U.S. adults watching the show is not greater than 12% (fails to reject H0: p = 0.12) when, in reality, the true proportion is greater than 12%. This could result in the show being canceled despite having a substantial viewership.
In summary, a Type I error in this setting would be the network wrongly concluding that more than 12% of U.S. adults watch the show, while a Type II error would be the network failing to recognize that the true proportion of viewers exceeds 12%. These errors can have significant implications for the network's decision-making regarding the show's renewal.

2)The slope of the larger triangle is larger than the slope of the smaller triangle.
3)Tre triangles are congruent
4)The slopes of the two triangles are the same.
5)Line A
Answer:
1(d), 2(not correct) 3,4,5 given below
Step-by-step explanation:
1. the slopes are same as we know
m=tan theta=y/x so the slope is same
2. it will be 10 m= tan theta=y/x
or, slope =70-40/7-4=10
3. let x and y are the sides of the triangles
so for 1 triangle it will be x=5 and y=2
"" "" another one its the multiple of 5 and 2 such as x=10 and y=4
4. the two triangle lie on the same line as slopes are equal
1st one , slope=72/12=6
2nd one slope=144/24=6
as slopes equal so they are collinear.
5. i am sorry i am not sure about it
i took all the three lines. as the slope of 5 and 7 no triangleare same(m=0.75) and smaller than others then on line A
then slope of 8 and 9 no triangle are same(m=1.5) so on the line B
then slope of 6 and 10 are same (m=3) so on the line C

Devin is collecting signatures for a petition to open a new park in her town. She needs to collect at least 1,000
signatures before she can schedule a meeting with the mayor. She already has 380 signatures. If each petition page
holds 80 signatures, which inequality best shows how many more pages (p) Devin needs?
Answer:
P = t - f
Step-by-step explanation:
First we need to find how many pages in total she needs so 1,000/80 - 12.5 so 13 pages. Then 380/80 4.75 of a page filled so subtract that from 12.5 to get 8 pages left to fill.
let p = pages left to fill
let T = total pages needed

You decide to rent a cottage you own. You spend $400 getting the cottage ready to put on the rental market. Your costs for utilities run approximately $15 per day. You think you can charge $115 per night in rent. Part A: Write an equation that represents your costs, C, in dollars for x number of nights. Part B: Write and equation that represents the Revenue (income), R, in dollars for x number of nights. Part C: What is the solution to this system of equations? Interpret the meaning of the solution.
Answer:
Part AThe costs consist of one off payment to get the cottage ready and daily utility charges:
C = 400 + 15xPart BThe revenue is the sum of daily rental:
R = 115xPart CTo solve it as a system we make C= R or:
400 + 15x = 115xSolving we get:
400 = 115x - 15x400 = 100xx = 400/100x = 4It gives us:
C = 400 + 15*4 = 460R = 115*4 = 460The meaning of the solution is the number of nights we can pay off the costs and after 4 days we start to get profit.

suppose​ 30% of the people in your town talk on their cell phones and drive at the same time. if you stood on a busy street corner and watched 50 people drive​ by, about what proportion would you expect to see talking on their cell​ phones?
We can expect that about 15 out of the 50 people we observe would be talking on their cell phones while driving.
To calculate this, we simply multiply the proportion of people who talk on their cell phones while driving (30%) by the number of people we are observing (50):
30% * 50 = 0.30 * 50 = 15
Therefore, we can expect to see approximately 15 out of the 50 people we observe talking on their cell phones while driving. It is important to note that this is only an estimate and may not be exactly accurate due to random variation.

Answer:
a) The measure of the angle created by the car's turning would be 75°. This is because 4th Street is parallel to 3rd Street, thus the angle formed when the car turns onto King Avenue heading northeast would be a 90° angle, which is the same as the angle between 4th Street and 3rd Street.
b) The measure of the angle created by the car's turning would be 180°. This is because when the car is traveling southwest on King Avenue and turns left onto 3rd Street, it is essentially making a full turn to face the opposite direction.
c) The measure of the angle created by the car's turning would be 90°. This is because when the car is traveling northeast on King Avenue and turns right onto 3rd Street, it is essentially making a right angle turn as it transitions from one street to the other.

Givens
Start by looking at the 'distance' (number of spaces) between 1 and 10
a = 1
l = 10
n of terms = 4
L_4 = 10
a = 1
Equation
L_4 = a + (n - 1)*d
10 = 1 + (4 - 1)*d
10 - 1 = 3d
9 = 3d
9/3 = d
d = 3
So the terms you get from 1 to 10
1 4 7 10
Discussion
But we actually started at 1, not -11. Let's fill in the 3 blanks leading up to 1
-11 ____ ____ ____ 1
a = - 11
t = 5
L= 1
1 = - 11 + (5 - 1) d
1 = -11 + 4d Add 11
1+ 11 = 4d
12 = 4d
12/4 = d
d = 3
======================
Could we have done this more directly. Yes, we could have
a = - 11
t = 8 There are 8 terms in all.
L_8 = 10
L_9 = a + (n-1)d
10 = - 11 + (8-1)d
10+11 = 7d
21 = 7d
21/7 = d
d = 3
arrange the following in order of increasing radius as predicted: ne, na, li+, na+
The order of increasing radius as predicted is:
li+ < na+ < ne < na
Based on the periodic table, the trend for atomic radius is that it decreases from left to right across a period and increases down a group. Therefore, we can predict that the order of increasing atomic radius for the given ions and element is as follows: Ne < Na+ < Li+ < Na. This is because Ne is a noble gas with a full valence shell and the smallest atomic radius. Na+ and Li+ have lost one and two electrons respectively, resulting in a decrease in electron-electron repulsion and a smaller ionic radius than their respective neutral atoms. Finally, Na, being a larger atom than Li, will have a larger atomic radius due to more electron shells

Answer:
(ab - 6)(2ab + 5)
Step-by-step explanation:
Assuming you require the expression factorised.
2a²b² - 7ab - 30
Consider the factors of the product of the coefficient of the a²b² term and the constant term which sum to give the coefficient of the ab- term
product = 2 × - 30 = - 60 and sum = - 7
The factors are - 12 and + 5
Use these factors to split the ab- term
= 2a²b² - 12ab + 5ab - 30 ( factor the first/second and third/fourth terms )
= 2ab(ab - 6) + 5(ab - 6) ← factor out (ab - 6) from each term
