Answer:
1. angle Y, angle XYZ, and angle ZYX
2. angle PQR, angle SQR, and angle PQS
Step-by-step explanation:
1. The 3 ways to name the given angle are:
✔️The use of an alphabet of the vertex: angle Y
✔️The use of the three alphabets can be named in two ways with the middle alphabet representing the vertex:
angle XYZ
angle ZYX
2. The three different angle in the diagram consist of two adjacent angles that share the same side: angle PQR and angle SQR,
and the bigger angle that sums up the two internal angles, which is angle PQS
Find the area of the curve y= f(x) = x between x = 5 and x = 10
Answer:
the area of the curve y= f(x) = x between x = 5 and x = 10
[tex]A=\frac{75}{2}[/tex]
Step-by-step explanation:
Finding the area of the curve y = f(x) = x between x = 5 and x = 10Using the Area formula
[tex]A=\int _a^b\:f\left(x\right)dx[/tex]
As the area of curve lies between x = 5 and x = 10
so
a = 5, b = 10so the integral expression becomes
[tex]A=\int _5^{10}xdx[/tex]
[tex]\mathrm{Apply\:the\:Power\:Rule}:\quad \int x^adx=\frac{x^{a+1}}{a+1},\:\quad \:a\ne -1[/tex]
[tex]A=\left[\frac{x^{1+1}}{1+1}\right]^{10}_5[/tex]
[tex]=\left[\frac{x^2}{2}\right]^{10}_5[/tex]
[tex]=\frac{1}{2}\left[10^2-5^2\right][/tex]
[tex]=\frac{1}{2}\cdot \:75[/tex]
[tex]=\frac{75}{2}[/tex]
Therefore, area of the curve y= f(x) = x between x = 5 and x = 10
[tex]A=\frac{75}{2}[/tex]

Standard tests, such as the SAT or ACT or MCAT, tend to make extensive use of multiple-choice questions because they are easy to grade using software. If one such multiple choice question has possible correct answers of a, b, c, d, e, what is the probability of a wrong answer if the answer is a random guess
Answer:
4/5
Step-by-step explanation:
Given that:
Number of options = a, b, c, d, e
Number of correct answer choice = 1
Therefore, number of wrong answers = 4
Recall :
Probability = (number required outcome / number of total possible outcomes)
P(wrong answer) :
Number of Required outcome = number of wrong answer choices = 4
Total answers = 5
Hence,
P(wrong answer) = 4 / 5 = 0.8
The difference between two-thirds of a number and 4 is –92.
Answer:
The difference between 4 is –92 is 132
Answer:
Given - The difference between two- third of a no. and 4 is (-92)
Let the no. be X
TO Find - The no.
Solution -
Let the no. be X
Two - third of a no. = 3/2x
according to the question equation made is-
2/3x - 4 = (-92)
2/3x = (-92)+ (4)
2/3x = ( -88)
X = (-88) × 3/2
X= ( -264/2)
X = (-132)
30 points On a certain hole, a golfer knows that he has a 70% chance of reaching the green (putting surface) in one stroke, 20% in two strokes, 8% in three, and 2% in four or more. If he reaches the green on his first stroke, he has an 80% chance of putting the golf ball in the cup on his second stroke. If he does not reach the green on his first stroke, then he has a 30% chance of putting the golf ball in the cup on his second stroke. What is the probability that the golfer will reach the green in one stroke and put the ball in the cup on his second stroke?

Read the information below and answer the questions. Suppose a researcher wants to learn more about the mean attention span of individuals in some hypothetical population. The researcher cites that the attention span (the time in minutes attending to some task) in this population is normally distributed with the following characteristics: 20 36 . Based on the parameters given in this example, answer the following questions: 1. What is the population mean (μ)?
Answer:
The population mean (μ) = 26.
Step-by-step explanation:
a) Data and Calculations:
The population characteristics = 20 and 36
Total population of interest = 56 (20 + 36)
Number of groups in the population = 2
Therefore, the population mean (μ) = 56/2 = 28
b) Based on the parameters given in this example, the population mean equals the average of the group characteristic (attention span of individuals in minutes) or item of interest. The population mean is calculated by adding the values of the group characteristic and then dividing the result by the number of values.
What is the least common denominator of 1/2,2/3 and 3/8 OA) 48 OB) 24 O C) 16 OD) 12 plz help me
Answer:
24
Step-by-step explanation:
The required least common denominator (LCD) of 1/2, 2/3, and 3/8 is 24.
What is the least common denominator?The least common denominator has a defined factor that is least common among the factors of the denominator is called the least common denominator.
Here,
Rewrite each fraction with the least common denominator (LCD) of 24 by multiplying both the numerator and denominator by the appropriate factor:
1/2 = (1/2) * (12/12) = 12/24
2/3 = (2/3) * (8/8) = 16/24
3/8 = (3/8) * (3/3) = 9/24
Check that the fractions have the same denominator:
12/24, 16/24, and 9/24
Therefore, the least common denominator (LCD) of 1/2, 2/3, and 3/8 is 24.

Which of the following correctly describes the end behavior of the polynomial
function, f(x) = -3x4 +2x2 - x?
HELPPPPPP ASAAP
Answer:
A. Both ends go down.
General Formulas and Concepts:
Algebra II
End behavior - what the y-values are approaching as x approaches negative infinity or infinityStep-by-step explanation:
If we graph the function, we can see that when x goes to -∞, y also goes to -∞.
We also see that when x goes to ∞, y still goes to -∞.
Therefore, both ends of the graph would head towards -∞, making A. the correct answer choice.

Bill conducts a study during which he compares two, independent groups and he gets a significance value of .16 (i.e., p=.16). He looks at the means of the groups and sees the Group 1 Mean is 70 and the Group 2 mean is 77. He concludes they are different. (a) Why is Bill wrong? (b) What exactly does his p-value mean, in this instance?
Answer:
P-value is a parameter to compare with the significance level in order to make decisions about rejecting or not the hypothesis
Step-by-step explanation:
When you are developing a hypothesis test, in order to compare two means ( μ₁ and μ₂ ) you have two hypothesis
Null Hypothesis H₀ μ₁ = μ₂
And depending on the problem statement, the alternative hypothesis could be
Alternative Hypothesis Hₐ (1) μ₁ > μ₂
(2) μ₁ < μ₂
(3) μ₁ ≠ μ₂
Now if the result of the test determines that H₀ is rejected you accept in case
(1) μ₁ > μ₂
(2) μ₁ > μ₂
(3) μ₁ ≠ μ₂
In any case, you need a confidence Interval, and as consequence you established a significance level to do your test. These two concept defines the acceptance and the rejection region. Just for instance
CI = 90% means that the acceptance region is 90 %, and at the same time, the rejection area is 10 %. That 10 % will be used as follows,
Case 1 you are developing a one tail-test to the left ( side of the curve )
Case 2 you are developing a one tail-test to the right
Case 3 you are developing a two-tail test ( in that case you need to split α into two equal areas one for each tail.
Now P-value is a tool for decision is an area that you can compare with α to accept or reject H₀.
In our particular case suppose we are testing
H₀ μ₁ = μ₂
Hₐ μ₁ < μ₂
Let´s say CI = 95 then α = 5 % α = 0,05
And we get P-value = 0,16
Then area 0,16 > 0,05 Then we are in the acceptance region
(that condition really implies that z(s) < z(c)
Estimate the sum.

Step-by-step explanation:
To test whether an integer, $n$, is prime, it is enough to be sure that none of the primes less than or equal to the square root of $n$ divide $n$. If you want to check that a number between 900 and 950 is prime with this rule, what is the largest prime divisor you need to test
Answer:
the largest divisor is less than the square root of that number
Step-by-step explanation:
Pick any number between 900 and 950 . For example I choose 937 . Now taking the square root of 937 would give 30.61
So divide 937 with all the primes less than 30.61
937/2, 937/3, 937/5,...................937/29
29 would be the largest divisor which is less than the square root of 937 .
29< 30.61
But if you check 937 does not divide wholly with any of the primes hence it is a prime number itself.
If any number such 925 is chosen and it gets divided wholly by another prime like 5
925 /5= 185 so it is not a prime number
