Which equations are true for the values of x, y, and z?
Answers
The equations that are true for the values of x, y and z are :
x degrees + 65 degrees = 180 degreesx degrees = z degreesy degrees = 65 degreesWhat are the equations for x, y, and z ?The equations can be found based on the relationships between the variables as angles.
x and z are opposite each other which makes them congruent angles which means that they are the same value.
y and 65 degrees are also opposite each other which makes them congruent.
x and 65 degrees are on a straight line and so will add up to 180 degrees which is why the correct equation would be :
x degrees + 65 degrees = 180 degrees

Sofia ordered sushi for a company meeting. They change plans and increase how many people will be at the meeting, so they need at least 100 pieces of sushi in total.
Sofia had already ordered and paid for 24 pieces of sushi, so she needs to order additional sushi. The sushi comes in rolls, and each roll contains 12 pieces and costs $8.
Let R represent the number of additional rolls that Sofia orders.
1) Which inequality describes this scenario?
Choose 1 answer:
A) 12 + 24R ≤ 100
B) 12 + 24R ≥ 100
C) 24 + 12R ≤ 100
D) 24 + 12R ≥ 100
2) What is the least amount of additional money Sofia can spend to get the sushi they need?
dollars
Answers
Answer:
The answer is given below <3
Step-by-step explanation:
The options are not given but I would list the inequalities needed to solve this problem.
As a result of increase in people to attend meeting, the number of sushi needed to be ordered is 100 pieces. Sofia has already ordered 24 pieces. If R is the number of additional rolls that Sofia orders.
The number of additional rolls that Sofia orders (R) must be greater than or equal to the difference between the number of Sushi needed to be ordered and the number of Sushi that has already being ordered. It is given by the inequality:
R ≥ 100 - 24
R ≥ 76
If each roll contains 12 pieces, the number of rolls needed (n) is given by:
n ≥ R/12
n ≥ 76/12
n ≥ 6.33
n ≥ 7
If each roll cost $8, the money needed to buy the sushi is given as:
Cost ≥ 8(7) ≥ $56

Amy is draining an aquarium. The graph shows the amount of water (in liters) in the aquarium versus time (in minutes)
Answers
From the graph, we have the amount of water (in liters) on the y-axis and the time (in minutes) on the x-axis
a)
To obtain the amount of water at zero minutes, we will trace the y-value that corresponds with the value of zero on the x-axis: we will see this to be 270 liters
Therefore, at time zero minutes, the amount of water is 270 liters
b)
We will answer this by picking two points that lie along the straight line and calculate the slope. We pick the points:
\(\begin{gathered} (x_1,y_1)=(0,270) \\ (x_2,y_2)=(2,90) \end{gathered}\)We will proceed to calculate the slope as shown below:
\(\begin{gathered} slope(m)=\frac{y_2-y_1}{x_2-x_1} \\ \text{Substitute the values of the variables into the equation, we have:} \\ slope(m)=\frac{90-270}{2-0} \\ slope(m)=-\frac{180}{2} \\ slope(m)=-90l\text{/}min \end{gathered}\)The slope is -90 liters per minute.
The negative sign (-) means that as time increases, the amount of water in the aquarium decreases
The water decreases at a rate of 90 liters per minute

The perimeter of 14 and radius of 2.5
Answers
Answer:
The area of the regular polygon is 17.5.
Step-by-step explanation:
To find the area of the regular polygon with a perimeter of 14 and radius of 2.5, the following calculation must be performed, knowing that the area of a regular polygon arises from multiplying the perimeter by the apothem divided by two:
(14 x 2.5) / 2 = X
35/2 = X
17.5 = X
Therefore, the area of the regular polygon is 17.5.

Use the binomial distribution to compute the probability that exactly 28 of the employees work over forty hours per week.
Identify the following information required to find the probability of employees working over forty hours per week.
Provide your answer below:
n = trials
x = successes
p = probability of working over forty hours per week
Answers
The probability that exactly 28 of the employees work over forty hours per week using the binomial distribution is given below. Information required to find the probability of employees working over forty hours per week are as follows:
n = 54
x = 28
p = 0.35
Formula used in the binomial distribution is given below:
P(X=x) = nCx * p^x * q^(n-x)
Where:
P(X=x) is the probability of exactly x successes in n trialsn
Cx = n! / x!(n-x)!p = probability of success q = 1 - p = probability of failure.
The probability that exactly 28 of the employees work over forty hours per week can be found as:P(X=28) = 54C28 * 0.35^28 * 0.65^26= 0.1646Therefore, the probability that exactly 28 of the employees work over forty hours per week using the binomial distribution is 0.1646.

The expression is to be written in complete square method and the value will be equal to (x + 5/2)² + 7/4.
The expression x² + 5x + 8 is a quadratic polynomial and a quadratic polynomial is one which can be written in the form ax² + bx + c; where a, b and c are constant values and x is the independent variable. Now in order to write the expression by using completing square method we write the polynomial as
x² + 5x + 8
We divide the coefficient of x that is 5 by 2 so we get
x² + (5/2)x + 8
Now, we add and subtract the square of coefficient of x that is 5/2 so we get
x² + (5/2)x + 8 + (5/2)² - (5/2)²
From the above expression we get
(x + 5/2)² + 8 - 25/4
(x + 5/2)² + (32 - 25)/4
(x + 5/2)² + 7/4
Thus we have written the expression in the form (x + p)² + q as (x + 5/2)² + 7/4.

A food truck did a daily survey of customers to find their food preferences. The data is partially entered in the frequency table. Complete the table to analyze the data and answer the questions: Likes hamburgers Does not like hamburgers Total Likes burritos 49 92 Does not like burritos 75 38 Total 81 205
Answers
30.6% of survey respondents do not like both hamburgers and burritos, with the strongest association being that customers who like hamburgers are more likely to not like burritos.
Part A: The number of survey respondents that do not like hamburgers is 205 - 81 = 124.
Of these 124 respondents, 38 do not like burritos as well, so the percentage of respondents that do not like both hamburgers and burritos is 38 / 124 * 100% = 30.6%.
Part B: The marginal relative frequency of all customers who like hamburgers is 81 / (81 + 205) = 28.2%.
Part C: The conditional relative frequency of customers that like burritos given they like hamburgers is 49 / 81 = 60.5%.
The conditional relative frequency of customers that do not like burritos given they like hamburgers is 32 / 81 = 39.5%.
The conditional relative frequency of customers that like hamburgers given they like burritos is 49 / 141 = 34.8%.
The conditional relative frequency of customers that do not like hamburgers given they like burritos are 92 / 141 = 65.2%.

take all coins that are still on tails and keep flipping them until they land on heads. what is the expected number of total flips until all coins are on heads?
Answers
The probability that all coins show heads up is 1/16.
How to calculate the probabilityThe probability of one is 1/2: Half of the time (on average, as all numbers in this answer will be) it will show heads.
Of those times it shows heads, only half of the time will the second coin also show heads. We're down to a quarter of the time now.
Of those times the second coin shows heads, only half of the time will the third coin also show heads. This is 1/8.
And, of the times the third coin also shows heads, only half of the time will the fourth coin also show heads. Half of 1/8 is 1/16.
You can simplify this by calculating (1/2)^4.

for a graph of capacity (nF) Y-axis and the X-axis is the inverse of distance (mm^-1)
what is the unit of slope?
Answers
The unit of slope for a graph of capacity (nF) on the y-axis and the inverse of distance (mm^-1) on the x-axis depends on the specific units used for capacitance and distance.
Recall that the slope of a linear graph is given by:
slope = (change in y) / (change in x)
In this case, the change in y is given in units of capacitance (nF), and the change in x is given in units of the inverse of distance (mm^-1). Therefore, the unit of slope is:
(nF) / (mm^-1)
This can also be written as:
nF * mm
So, the unit of slope for this graph is "nanofarads times millimeters" (nF * mm).

x = 180° ÷ 9
x = 20°
Answer:
x = 20
Step-by-step explanation:
Co-interior angles (also called same-side interior angles) are two angles that are on the same side of the transversal and on the interior of (between) the two parallel lines.
Same-side interior angles theorem: If two parallel lines are cut by a transversal, then the same side interior angles are supplementary (add up to 180º).
Therefore, if 2x and 7x are co-interior:

The mean and variance are known as the _____
of a distribution.
Answers
Answer:
The mean and variance are known as the parameters of a distribution.
Step-by-step explanation:
The mean and the variance are parameters of a distribution. Parameters are constantly estimated in Statistics using samples of values of a population because they are often unknown.
They characterize a quantitative aspect of a probability distribution, and completely determined the distribution. For example, in the normal distribution, the mean, \( \\ \mu\), and the variance, \( \\ \sigma^{2}\), determined this distribution.
Most of the time, the standard deviation, \( \\ \sigma\), is more used than the variance because is in the same units that the mean.
In this way, we can say that these parameters "tell us" where the central point of the distribution is (this is the case for the mean), and also, how spread the values of a probability distribution are (the case for variance or the standard deviation).
