Determine the measure of ∠Q, rounded to the nearest tenth of a degree.
Question 19 options:
A)
36.1°
B)
22.8°
C)
66.0°
D)
73.5°
Answer:
D) 73.5º
Step-by-step explanation:
Law of sines
sinQ/15 =sin50.1/12
multiply both sides by 15
sinQ = sin50.1/12 * 15
sinQ = 0.958956439769124
Q = arcsin0.958956439769124
Q = 73.5º
It is known that when a specific type of radish is grown in a certain manner without fertilizer the weights of the radishes produced are normally distributed with a mean of 40g and a standard deviation of 10g. When the same type of radish is grown in the same way except for the inclusion of fertilizer, it is known that the weights of the radishes produced are normally distributed with a mean of 140g and a standard deviation of 40g. Determine the proportion of radishes grown
Answer: hello your question is incomplete below is the missing part
Determine the proportion of radishes grown without fertilizers with weight less than 50grams
answer : p( x < 50 ) = 0.84
Step-by-step explanation:
Radish grown in without fertilizers ( normally distributed )
mean = 40 g
standard deviation = 10 g
Radish grown with fertilizers ( normally distributed )
Mean = 140 g
standard deviation = 40 g
Determine the proportion of radishes grown without fertilizers with weight less than 50 grams
lets assume x = radish without fertilizers
y = radish with fertilizers
hence
p( x < 50 ) = P ( (x-μ / б) < [tex]\frac{50-40}{10}[/tex] )
= p ( z < 1 ) = 0.5 + p ( 0 < z < 1 )
p( x < 50 ) = 0.5 + 0.3413 = 0.8413
attached below is the distribution related to this solution

The amount of orange juice in a bottle is modeled by the equation y=128-8x, where y is the number of ounces of juice in the bottle, and x is the number of servings or juice poured from the bottle.
How many servings are in a bottle?
Answer:
There are 16 servings in the bottle.
Step-by-step explanation:
The equation for the amount of juice left in the bottle is:
y = 128 - 8*x
Where x is the number of servings of juice poured from the bottle.
The total number of servings that are in the bottle is the value of x such that we have y = 0 (because in that point, we do not have more juice left)
Then we need to solve:
y = 0 = 128 - 8*x
8*x = 128
now we can just divide both sides by 8
x = 128/8 = 16
There are 16 servings in the bottle.

What is the median Value of the data sat shown on the line plot?
Answer:
6 is the median of the data set.
Step-by-step explanation:
First, write all the numbers out.
1, 2, 3, 3, 4, 4, 5, 5, 5, 6, 6, 6, 6, 7, 7, 7, 8, 8, 8, 9, 9, 11
Next, highlight the one that is in the middle.
1, 2, 3, 3, 4, 4, 5, 5, 5, 6, 6, 6, 6, 7, 7, 7, 8, 8, 8, 9, 9, 11
If you have an even amount of numbers, or two numbers in the middle you have to find the mean between those numbers but because they are both 6 the median is still 6.
Have a wonderful day! :)

Me and Skid believe the awnser is A, Triangle!
A triangular prism has two congruent, parallel bases and three lateral sides.
What is a prism?
A prism is a polyhedron that has two n-sided bases and n number of lateral sides. Those two bases are exactly the same.
A pentagon and a rectangle are two dimensional figures. Hence, there are neither parallel bases nor lateral sides. Whereas a prism is a three dimensional figure consists of two congruent, parallel bases and three lateral sides.

Nafeli is taking a multiple-choice exam with 10 questions and 3 choices per question. For eachquestion, there are two equally likely possibilities, independent of other questions. In the firstpossibility, she knows the answer, in which case she answers the question correctly. In the secondpossibility, she guesses the answer with probability of success 1/3.1. Given that Nafeli answered correctly the first question, what is the probability that she knewthe answer to that question
Answer:
0.75 = 75% probability that she knewthe answer to that question
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Answered correctly.
Event B: Knew the answer.
Probability of answering correctly:
0.5(knows the answer)
1/3 of 1 - 0.5 = 0.5(didn't know but guessed correctly). So
[tex]P(A) = 0.5 + 0.5\frac{1}{3} = 0.6667[/tex]
Probability of answering correctly and knowing the answer:
0.5, which means that [tex]P(A \cap B) = 0.5[/tex].
What is the probability that she knew the answer to that question?
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.5}{0.6667} = 0.75[/tex]
0.75 = 75% probability that she knewthe answer to that question

2. According to the chart, 11% of all students at this high school have GPA of 3.5 of higher and 14% have GPAs of 1.5
or lower. What percentage of all students have GPAs between 1.5 and 3.5? Show your work. Do not round your
result.
Answer:
75% of all students have GPAs between 1.5 and 3.5
Step-by-step explanation:
11% of all students at this high school have GPA of 3.5 of higher:
This means that a GPA of 3.5 is in the 100 - 11 = 89th percentile, that is, a student that gets a GPA of 3.5 has a higher GPA than 89% of students.
14% have GPAs of 1.5 or lower.
This means that a GPA os 1.5 is in the 14th percentile, that is, a student that gets a GPA of 1.5 has a higher GPA than 14% of students.
What percentage of all students have GPAs between 1.5 and 3.5?
Percentile of 3.5 subtracted by the percentile of 1.5.
89 - 14 = 75%.
75% of all students have GPAs between 1.5 and 3.5

Use Euler's formula to find the missing number.
Vertices: 23
Edges: 39
Faces: ?
A. 12
B. 14
C. 16
D. 18
Answer: D. 18
Step-by-step explanation:
Euler's formula is Faces + Vertices = Edges + 2
Faces = Edges - vertices + 2
Faces = 39-23 + 2 = 18
Euler's formula is given by the formula F + V = E + 2. The number of faces in the given object is 18.
What is Euler's Formula?Euler's formula is given by the formula F + V = E + 2, in which F is the number of faces, V is the number of vertices, and E is the number of edges. For instance, a cube fits this formula since it has 6 faces, 8 vertices, and 12 edges.
The number of vertices and edges in the object is 23 and 39, respectively. Therefore, using Euler's formula the number of faces can be written as,
F + V = E + 2
F + 23 = 39 + 2
F = 39 + 2 - 23
F = 18
Hence, the number of faces in the given object is 18.
