Answer:
statistical hypothesis.
Step-by-step explanation:
A statistical hypothesis has the central objective of assisting in a decision-making process about one or more populations in relation to the sample data, allowing the observance of whether the information found in the samples will support the statistical hypothesis.
It is necessary to know concepts of mathematical probability to perform the tests, the most used models for this purpose are the fisher method, by Neyman-Pearson and Bayes.
The variables used in a statistical hypothesis are: the Null Hypothesis, the one that is assumed to be the true one, the Alternative Hypothesis, the one that is used when there is no statistic to analyze the hypothesis given as true, the Type I Error, related to the probability of rejection of the null hypothesis, and the Type II Error, which is the probability of rejection of the alternative hypothesis if it is true.

In AABC, the measure of ZB=90°, AC = 50,
CB = 30, and BA = 40. What ratio
represents the tangent of ZA?
Help ASAP please!!!!
Answer:
tanA = 3/4
General Formulas and Concepts:
Trigonometry
tan∅ = opposite over adjacentStep-by-step explanation:
Step 1: Define
Looking at ∠A, finding tangent
Step 2: Identify
opposite leg of ∠A = CB = 30
adjacent leg of ∠A = AB = 40
Step 3: Write ratio
Substitute: tanA = 30/40Simplify: tanA = 3/4And we have our final answer!
Solve
4 - 3|x + 1| < -17
Answer: x > 6, x < -8
Subtract 4 from both sides.
−3∣x+1∣<−17−4
Then simplify -17 - 4 to -21.
−3∣x+1∣<−21
Divide both sides by −3.
|x + 1| > -21/-3
Two negatives make a positive.
|x + 1| > 21/3
simplify 21/3 to 7
Break down the problem into these 2 equations.
x + 1 > 7
-(x + 1) > 7
Solve the 1st equation: x + 1 > 7
x > 6
Solve the 2nd equation: -(x + 1) > 7
x < -8
last collect all solutions
x > 6, x < -8

QUICK!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! The ratio of the hours the Teenage Mutant Ninja Turtles spend training,
to the hours they spend eating pizza is 8:3. If they spend 24 hours
training, how much time do they spend eating pizza?
A 6
B 12
C 9
D 36
Answer:
6 hours
The difference between the ratio numbers is 8-3 = 5. That corresponds to the 10-hour difference between training hours and pizza-eating hours. Thus, each ratio unit stands for 2 hours. The 3 ratio units spent eating pizza stand for ...
3×2 hours = 6 hours eating pizza

Give an example for a pair of alternate interior angles, a pair of corresponding angles, and a pair of alternate exterior angles,and a pair of alternate interior angles.
Answer:
One way to identify alternate exterior angles is to see that they are the vertical angles of the alternate interior angles.
Step-by-step explanation:
so if I was you I would use that strategy to try to find the pair of the Alternate exterior angles.
so the agles are probably 1 and 7 but i don’t want you to get it wrong so here’s a picture Of an example.

How does the concept of beta impacts financial decision making?
Answer:
The concept of beta impacts financial decision making by providing information volatility or systematic risk of a security.
The information that provided by the concept of beta would take form in a comparison between your chosen securities with other securities that exist in the market. For investors who prefer low risk but small and steady return, they can use the concept of beta to find out the securities with low level of volatility.

A random sample of 12 chemists from Washington stats shows an average salary of $39,420 with a standard deviation of $1659. A random sample of 26 chemists from New Mexico has an average salary of $30,215 with a standard deviation of $4116. Find the 98% confidence interval of the difference of means.
Answer:
Step-by-step explanation:
Given that :
μ1 = 39420 ; σ1 = 1659 ; s1 = 12
μ2 = 30215 ; σ2 = 4116 ; s2 = 26
df1 = 12 - 1 = 11
df2 = 26 - 1 = 25
98 % confidence interval of the difference in sample means :
Pooled Variance :
S²p = ((df1 * s1²) + (df2 * s2²)) / (df1 + df2)
((11×1659^2)+(25×4116^2))÷(11+25) = 12605874.75
Standard Error :
√(S²p/n1) + (S²p/n2)
√(12605874.75/12) + (12605874.75/26)
= 1239.0847
A casting director wishes to find one male and one female to cast in his play if he plans to audition seven males and eight females in how many different ways can this be done
There are 7 males and 8 females out of which we 1 male and 1 female is to be selected.
Number of ways to select 1 male from 7 are [tex]^7C_1[/tex].
Number of ways to select 1 female from 8 are [tex]^8C_1[/tex].
So, number of ways to select 1 male and 2 female is :
[tex]n = ^7C_1 \times ^8C_1\\\\n = 56[/tex]
Therefore, total number of ways are 56.
Hence, this is the required solution.

Using the given sets of points, identify slope (m), y-intercept (b), and write the equation. (0, 4) and (-1, -1)
Answer:
y = 5x + 4
Step-by-step explanation:
Its a given that the y intercept is 4 because on that point x = 0
B= 4
now you solve for your slope using y - y' / x - x'
when you plug in the numbers you get -1 - 4 / -1 - 0 which simplfies to -5 / -1 which simplifies just to 5, so we know the slope is = 5
now we just plug In and the base equation is y = mx + b.
