Answer:
C. 9,40,41
Step-by-step explanation:
The last number in any answer is always the hypotenuse and that is what u will use, because according to the formula:
hypotenuse² = opposite²+adjacent² so;
41²=40²+9²
1,681 = 1600 + 81
1,681 = 1,681
so it is balanced and that means the answer is ✅

Students in an introductory statistics course were asked the following questions as part of a class survey:(1) What is your gender, male or female?(2) On average, how many hours of sleep do you get per night?(3) What is your bedtime: 8pm-10pm, 10pm-12am, 12am-2am, later than 2am?(4) How many countries have you visited?(5) On a scale of 1 (very little) - 5 (a lot), how much do you dread this semester? Identify the variables in the survey. Classify each variable as numerical or categorical. For each numerical variable, identify whether it is continuous or discrete. For each categorical variable, identify whether it is nominal or ordinal.
Answers:
Gender = categorical, nominal variable
Sleep length = numerical, continuous
Bedtime = categorical, ordinal
Number of countries visited = numerical, discrete
Scale of dreading semester = categorical, ordinal
=========================
Explanation:
Gender is categorical because there are two categories or labels, male or female. It is nominal because we simply attach names to each label and we can't sort them or order them from highest to lowest. There is no ranking for gender.
Sleep length is numerical as it deals with numbers. I put continuous because someone could write 2.5 hours or 3.75 hours. If whole numbers are only allowed, then the variable would be discrete.
The bedtime portion is categorical as each time slot is a category. Like with the first part, they are simply labels. We can order them however from earliest to later on, which is why this variable is ordinal.
The number of countries visited is numeric as expected, and it's also discrete because we can't visit 0.1 of a country. By "visit", I mean step foot in any part of the country for any length of time. It does not mean you have to explore every square inch of the territory.
The last part is categorical and ordinal. The scale ranking is ordered for us from 1 to 5. Despite the fact we have numbers here, the data is not numerical as the numbers 1 through 5 represent labels of "very little" through "a lot".
The expression means the product of 5 and the difference of three times r minus 10. If r = 4, the value of the expression is .
Answer:
10
Step-by-step explanation:
"three times r" = 3r
"three times r minus ten" = 3r - 10
"product of 5 and the difference of three times r minus ten"
= 5 (3r - 10)
given that r = 4,
the expression becomes
5 (3r - 10)
= 5 [3(4) - 10]
= 5 [12 - 10]
= 5 (2)
= 10
A flask contains 12% acid solution and the remaining volume is water. If the flask is 8.52 inches high and the diameter is 3.71 inches. What percent of the mixture by volume is water?
Answer:
Percent of water in the mixture=88%
Which is 81.07 square inches of the total volume
Step-by-step explanation:
Volume of the flask=πr^2h
π=3.142
radius=diameter/2
=3.71/2
=1.855
height=8.52 inches
Volume of the flask=πr^2h
=3.142*(1.855)^2*8.52
=3.142*3.441025*8.52
=92.115688686
Approximately 92.12 square inches
Flask contains 12% acid solution and the remaining volume is water
Percentage of water =Total percentage - acid solution percentage
=100%-12%
=88%
Percentage of Water =88%
Percentage of the mixture by volume is water=88% of the total volume
=88/100*92.12
=81.0656 square inches
Approximately 81.07 square inches

Second sprinter takes a stride of 75 cm
= 100/0.75 = 133 1/3 steps
Find x please help thank you
Answer: x=(7√6)/2
Step-by-step explanation:
To find x, we would have to find the hypotenuse of the 45-45-90 triangle. First, we would have to find the hypotenuse by using the 30-60-90 triangle on top to find it.
For a 30-60-90 triangle, the hypotenuse is 2x in length. the x is the same in all sides. All you would have to do is to plug it in. The leg opposite of 60° is x√3 in length. the leg opposite of 30° is x in length.
Since we know that 7 is opposite of the 30° angle, we know that x is 7. Across fron 60° is the hypotenuse of the 45-45-90 triangle. That leg is x√3. We plug in x=7 and get 7√3.
The hypotenuse of the 45-45-90 triangle is x√2 and the legs are both x. We can set 7√3 equal to x√2 to find x of the missing side.
7√3=x√2 [divide both sides by √2]
x=(7√6)/2
Now, we know x=(7√6)/2.
The owner of a music store gathered data from several schools about the number of students in their concert and marching bands. The
scatter plot shows the data she gathered and the line of best fit.
Answer:
25 students
Step-by-step explanation:
Using the line of best fit, we want to deduce the number of students predicted to be in the marching band given that there are 35 in the concert band.
To deduce this, what we need to do is to go to the point where we have 35 on the concert band axis i.e the x-axis, then trace it upto the line of best fit.
Then from the line of best fit, now trace to the y-axis.
This gives an answer 25.
Read the following two statements. Then, if possible, use the Law of Detachment to draw a conclusion. If two figures are congruent, their areas are equal. The area of ABCD equals the area of PQRS. I will make you a brainllest
Answer:
not possible
Step-by-step explanation:
The Law of Detachment is:
If p, then q. p is true. We can then conclude q is true.
For example:
If it rains, the grass gets wet. It is raining. Then the grass is wet.
In the problem in this post, it is not possible to use the Law of Detachment because we have:
If p then q. q is true. We are not told p is true, so we cannot conclude q is true.
Answer: not possible

After two weeks of hard work at Sweet Sundae Ice Cream Shop, Zack finally got his first paycheck! He deposited $120.00 into his savings account. Then, he put the remaining $56.74 in his checking account. Let p represent how much money Zack got paid. Which equation models the problem? p + 56.74 = 120.00 or p - 120.00 = 56.74 4) Solve this equation to find how much money Zack got paid.
Answer:
p - 120.00 = 56.74; p = $176.74.
Step-by-step explanation:
Out of the two equations, p - 120.00 = 56.74 would make the most sense. That is because it means that his paycheck minus the 120 that he deposited into savings is equal to the remaining balance.
We solve p - 120.00 = 56.74 by adding 120 to both sides.
p - 120 + 120 = 56.74 + 120
p = 176.74.
So, Zack got paid $176.74. That's a lot of money!

You want to know whether the students in your school enjoy the school lunch. You survey every student in your class. Is this survey biased or unbiased?
Answer:
biased
Step-by-step explanation:
on my quiz good luck
The survey is biased because a biased sample favors one or more segments of the population over others.
What is a survey?A survey is a means of gathering information from a sample of people using pertinent questions with the goal of understanding populations as a whole.
We have:
You want to know whether the students in your school enjoy the school lunch.
As we know,
A biased sample favors one or more segments of the population over others, whereas an impartial sample gives everyone in the population an equal chance of being chosen.
The population is the collection of data with the same entity that is linked to a problem. The sample is a subset of the population, yet it is still a part of it
Thus, the survey is biased because a biased sample favors one or more segments of the population over others.

Answer:
Option (B)
Step-by-step explanation:
By using the property of a triangle → " Sum of interior angles of a triangle is 180°"
Therefore, (4x - 40) + (x + 20) + x = 180°
(4x + x) + (-40 + 20) = 180°
5x - 20 = 180
5x = 180 + 20
5x = 200
x = 40
Therefore, value of x will be 40.
Option (B) will be the correct option.

If a vehicle travels 25x miles in 2 hours, what is the vehicle's average speed, in miles per hour.
Given that a vehicle travels 25 miles in 2 hours, determine the average speed of the vehicle in miles per hour.
Work:
In order to find the average mph of the vehicle, you have to divide the distance the vehicle travels in a certain period of time by that amount of time.
So, in this case, the vehicle traveled 25 miles in 2 hours, so you would divide 25 by 2.
25/2 = 12.5
That means, the vehicle is traveling at a speed of 12.5 mph.
Thus, the average speed of the vehicle is 12.5 miles per hour (mph).

write the coordinate point for the vertex of this parabola x=-1/8y^2
Answer:
(0,0)
Step-by-step explanation:
x = -⅛y²
The equation exchanges x and y, so this is a sideways parabola.
It opens to the left because the coefficient of y² is negative.
The vertex form of a sideways parabola with its vertex at (h, k) is:
x = a(y – k)² + h
Your equation is
x = -⅛(y - 0)² + 0
By comparing the two equations, we find that
h = 0; k = 0.
The vertex is at (0, 0).
The Figure shows your parabola with its vertex at (0,0).

The number of deaths by road as recorded in a country is 2 per 50,000 of the population. Find the probability that in a town of 100,000 inhabitants within the country (a). between one and three inclusive, and (b). between two and five deaths by road will be recorded.
Answer:
(a) 0.635
(b) 0.498
Step-by-step explanation:
(a) The probability distribution is calculated using the cumulative distribution function of the Poisson as follows;
CDF = [tex]F(x)=e^{-\lambda t}\sum_{i = 0}^{\left | x \right |}\dfrac{\lambda t^{i}}{i!}[/tex]
For x = three we have;
CDF = 0.781
For x = one we have;
CDF = 0.1465
Therefore, the probability that between one and three inclusive = 0.781 - 0.1465 = 0.635
(b) For x = 2 we have;
CDF = 0.4395
For x = one we have;
CDF = 0.9378
Therefore, the probability that between one and three inclusive = 0.9378- 0.4395= 0.498

Answer:
124
Step-by-step explanation:
First subtract 6 to both sides.
[tex]\sqrt[5]{249-2x} = 1[/tex]
Then take the 5th power of both sides to remove the radical.
[tex]249-2x=1^5[/tex]
Which is essentially:
-2x = 1 - 249
-2x = -248
Divide both sides by -2
x = 124
And there ya go :)
Answer:
x = 124
Step-by-step explanation:
[tex]6 + \sqrt[5]{249 - 2x} = 7 \\ \sqrt[5]{249 - 2x} = 7 - 6 \\ \sqrt[5]{249 - 2x} = 1 \\ {\sqrt[5]{249 - 2x} }^{5} = {1}^{5} [/tex]
[tex]249 - 2x = 1 \\ - 2x = 1 - 249 \\ - 2x = - 248 \\ \frac{ - 2x}{ - 2} = \frac{ - 248}{ - 2} [/tex]

Discuss the validity of the following statement. If the statement is always true, explain why. If not, give a counterexample. If Upper P (Upper E )plus Upper P (Upper F )equals Upper P (Upper E union Upper F )plus Upper P (Upper E intersect Upper F ), then E and F are mutually exclusive events.
Answer:
[tex]P(E \cup F)=P(E)+P(F)[/tex].
Step-by-step explanation:
Given the statement
If [tex]P(E)+P(F)=P(E \cup F)+P(E \cap F)[/tex], then E and F are mutually exclusive events.
If two events are mutually exclusive, they have no elements in common. Thus, P(E∩F)=0.
Therefore, the statement is always true as P(E∩F)=0
For mutually exclusive events:
[tex]P(E \cup F)=P(E)+P(F)[/tex].
A security alarm requires a four-digit code. The code can use the digits 0–9 and the digits cannot be repeated. What is the approximate probability that the code only contains odd numbers? 0.0005 0.00099 0.012 0.02381
Answer:
0.02381
Step-by-step explanation:
As we know that
We have 10 digits i.e 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 out of these 5 are odd digits 1, 3, 5, 7, 9.
A security alarm needs a code of four digits that includes only odd values
In the first position of the code is 1 digit from 5 odd digits.
In the second position of the code is 1 digit from 4 digits left.
In the third place it is 1 from 3 digits left
And the last fourth position is 1 from 2 odd digits left
Now we can generate 5: 4: 3: 2 = 120 distinct four-digit code only with odd different numbers in total.
Likewise we can count how much of different codes you can generated from all digits
In the first position of the code it is 1 digit from 10 digits,
In the second position of the code it is 1 digit from 9 digits left,
In the third place it is 8 digits left
And the last fourth position it is 7 digits left.
Now overall you can generate 10:9:8:7 = 5040 that contains different four-digit code by considering different digits.
So, the probability is
[tex]Pr=\dfrac{120}{5040}[/tex]
[tex]=\dfrac{1}{42}[/tex]
[tex]\approx 0.02381 .[/tex]

The system of equations y = one-fourth x minus 5 and y = negative one-half x minus 3 is shown on the graph below.
The question is incomplete! Complete question along with answer and step by step explanation is provided below.
Question:
The system of equations y = one-fourth x minus 5 and y = negative one-half x minus 3 is shown on the graph below.
Which statement is true about the solution to the system of equations? The x-value is between 2 and 3, and the y-value is between –4 and –5. The x-value is between –4 and –5, and the y-value is between 2 and 3. The x-value is between –2 and –3, and the y-value is between 4 and 5. The x-value is between 4 and 5, and the y-value is between –2 and –3.
Answer:
The solution is
[tex](x, y) = (2,67, -4.33)[/tex]
Therefore, the correct statement is
The x-value is between 2 and 3, and the y-value is between –4 and –5.
Step-by-step explanation:
The given equations are
Equation 1:
[tex]y = \frac{1}{4}x - 5[/tex]
Equation 2:
[tex]y = -\frac{1}{2}x - 3[/tex]
The point of intersection is given by
[tex]\frac{1}{4}x - 5 = -\frac{1}{2}x - 3 \\\\\frac{1}{4}x + \frac{1}{2}x = 5 - 3 \\\\\frac{3}{4}x = 2 \\\\x = \frac{2 (4)}{3} \\\\x = \frac{8}{3} \\\\x = 2.67[/tex]
The corresponding y value is
[tex]y = \frac{1}{4}x - 5 \\\\y = \frac{1}{4}(\frac{8}{3}) - 5 \\\\y = \frac{2}{3} - 5 \\\\y = -\frac{13}{3} \\\\y = -4.33[/tex]
So the solution is
[tex](x, y) = (2,67, -4.33)[/tex]
Therefore, the correct statement is
The x-value is between 2 and 3, and the y-value is between –4 and –5.
