Answer:
[tex](\dfrac{9}{2}, \dfrac{13}{2})[/tex]
Step-by-step explanation:
The coordinates of A = (2,9)
The coordinates of B = (7,4)
Let M (x,y) be the mid point of A and B.
[tex]M(x,y)=(\dfrac{x_1+x_2}{2}),(\dfrac{y_1+y_2}{2})\\\\=\dfrac{2+7}{2}, \dfrac{9+4}{2}\\\\=(\dfrac{9}{2}, \dfrac{13}{2})[/tex]
So, the coordinates of mid point of A and B is [tex](\dfrac{9}{2}, \dfrac{13}{2})[/tex].

Answer:
B, 5/4s
Step-by-step explanation:
If something increases by 1/4, it means that it is the original number + 1/4 of it.
Ex: x + 1/4x = 5/4x
So if we substitute s for x, the answer must be 5/4s, or B
Calculate the areas of these rectangles
Answer:
The answer is below
Step-by-step explanation:
A rectangle is a quadrilateral (four sides) with two pairs of equal opposite and parallel sides. All the four angles in a rectangle are equal to 90° (right angle). The diagonals of a rectangle are equal and bisect each other.
The area of a rectangle = length * breadth
a) Area = length * breadth = 8 cm * 3 cm = 24 cm²
b) Area = length * breadth = 5.2 cm * 7.7 cm = 40.04 cm²
Your school is planning a fundraising dinner. The expense for this event must not exceed $2,475.00. The team organizing the event has calculated that the cost per adult guest will be $18.00 and the cost per child guest will be $9.00. The venue can hold no more than 150 guests. The question is If the event were held in a venue that can accommodate 200 guests.
Required:
What is the maximum number of adults who could attend if the event fills the venue to capacity?
Answer:
75 adults
Step-by-step explanation:
Let
x = number of children
y = number of adults
x + y = 200 (1)
9x + 18y = 2,475 (2)
From (1)
x = 200 - y
9x + 18y = 2,475
9(200 - y) + 18y = 2,475
1800 - 9y + 18y = 2,475
- 9y + 18y = 2,475 - 1800
9y = 675
y = 675/ 9
y = 75 adults
Substitute y = 75 into (1)
x + y = 200
x + 75 = 200
x = 200 - 75
x = 125 children
The maximum number of adults who could attend if the event fills the venue to capacity is 75

Which of the following is NOT a common characteristic of a binomial distribution?
Question 28 options:
There are exactly two possible outcomes: success and failure.
The probability of success is the same in all trials.
There are a fixed number of observations.
You should perform x trials until you observe a success.
Each trial is independent
Answer:
You should perform x trials until you observe a success.
Step-by-step explanation:
By process of elimination:
A binomial experiment is a statistical experiment that must meet certain requirements:
Each outcome is either a success (P) or a failure (Q).
All trials are independent.
There are a fixed number of "n" trials.
The probability of success, p, is the same for each trial.
The probability of success, p, is the same for each trial.
You should perform x trials until you observe a success.
We have given that,
There are exactly two possible outcomes success and failure.
We have to determine the following is NOT a common characteristic of a binomial distribution.
By process of elimination
A binomial experiment is a statistical experiment that must meet certain requirements
Each outcome is either a success (P) or a failure (Q).
What is the independent probability?
Independence is a fundamental notion in probability theory, as in statistics and the theory of stochastic processes.
All trials are independent.
There are a fixed number of n trials.
The probability of success, p, is the same for each trial.

The competitive advantage of small American factories such as Tolerance Contract Manufacturing lies in their ability to produce parts with highly narrow requirements, or tolerances, that are typical in the aerospace industry. Consider a product with specifications that cal for a maximum variance in the lengths of the parts of 0.0008. Suppose the sample variance for 30 parts turns out to be
s2 = 0.0009.
Use
α = 0.05
to test whether the population variance specification is being violated.
State the null and alternative hypotheses.
H0: σ2 ≤ 0.000
Ha: σ2 > 0.0008
H0: σ2 = 0.0008
Ha: σ2 ≠ 0.0008
H0: σ2 ≥ 0.0008
Ha: σ2 < 0.0008
H0: σ2 > 0.0008
Ha: σ2 ≤ 0.0008
H0: σ2 < 0.0008
Ha: σ2 ≥ 0.0008
Find the value of the test statistic.
Find the p-value. (Round your answer to four decimal places.)
p-value =
State your conclusion.
A. Reject H0. The sample does support the conclusion that the population variance specification is being violated.
B. Reject H0. The sample does not support the conclusion that the population variance specification is being violated.
C. Do not reject H0. The sample does support the conclusion that the population variance specification is being violated.
D. Do not reject H0. The sample does not support the conclusion that the population variance specification is being violated.
Answer:
1. H0: σ2 ≤ 0.0008
Ha: σ2 > 0.0008
2. test statistic = 32.625
3. p value = 0.2931
4. D
Step-by-step explanation:
s² = 0.0009
alpha = 0.05
σ² = 0.0008 this is the value that we would be testing
1. hypothesis:
H0: σ2 ≤ 0.0008
Ha: σ2 > 0.0008
2. test statistic:
X² = (n-1/σ²)s²
= ((30-1)/0.0008)0.0009
= 32.625
3. p-value:
P(X² > 32.63) = 0.2931
4. conclusion:
the p-value at 0.2931 is greater than alpha at 0.005, (0.2931>0.05). So the correct option is D. we do not reject H0. the sample does not support conclusion that the population variance specification is being violated.

Answer:
I think it's "C"
Step-by-step explanation:
Because a function is the independent variable to the dependent variable... Since, the cost relies on the weight, the cost is dependent. While, the weight is independent. I don't know if I'm right, I kinda suck at math

Answer:
geometricarithmeticneither (Fibonacci sequence)Step-by-step explanation:
If ratios are the same, it is geometric:
8/4 = 16/8 = ... = 2
If differences are the same, it is arithmetic:
-4-(-8) = 0 -(-4) = ... = 4
If neither is the case, it is neither:
3-2 ≠ 5 -3
3/2 ≠ 5/3
In this last sequence we see that differences equal the previous term. This is characteristic of the Fibonacci sequence, which sees wide use in Nature, and has a relationship to the Golden Ratio. (The ratios of successive terms approach the golden ratio (1+√5)/2 ≈ 1.618.)
