Answers
Answer:
-5
Step-by-step explanation:
[tex]y=-5x[/tex]
The equation given is in slope intercept form.
A slope-intercept equation that passes through the origin would not have the '+ b' part because there is no intercept.
[tex]y=-5x+0[/tex]
When there is no intercept we would not write the '+ 0'.
The slope given is -5.

The set of life spans of an appliance is normally distributed with a mean y = 48 months and a standard deviation or
8 months. What is the z-score of an appliance that stopped working at 64 months?
Answers
Answer:
The set of life spans of an appliance is normally distributed with a mean µ= 48 months and a standard deviation σ= 8 months. ... Thanh finds that his grade on the test has a z-score of -2.5. ... are normally distributed, and the probability that the city gets more than 43.2 inches of rain in a year is given by P(z≥1.5)=0.0668.
Step-by-step explanation:
=============================================================
Explanation:
The raw score is x = 64, and we want to find its corresponding z score.
The mean and standard deviation are mu = 48 and sigma = 8 respectively.
The z score is...
z = (x-mu)/sigma
z = (64-48)/8
z = 16/8
z = 2
A z score of 2 means we're 2 standard deviations above the mean.
As the formula above implies, we find the difference from the raw score (x) to the mean (mu). Then we divide over sigma to find out how many sigma steps we have to take to go from mu to x.
A negative z score would indicate the raw score is below the mean.

There are typically 12 decision variables and 7 constraints. There are typically 4 decision variables and 3 constraints. There are typically 12 decision variables and 12 constraints. There are typically 7 decision variables and 7 constraints.
Answers
Answer:
There are typically 12 decision variables and 7 constraints. ( option A )
Step-by-step explanation:
Given that there are 4 sources and 3 destinations The true statement is :
There are typically 12 decision variables and 7 constraints.
Because : In general linear programming optimization
number of decision variables in transportation = destination * source
= 3 * 4 = 12 variables
number of constraints = destination + sources = 3 + 4 = 7 constraints

What is the measure of angle LMQ
Answers
Answer:
Option B, 42°
Hope this helps!
The measure of ∠LMQ = 42°.
What is an angle measure?When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
In the ΔQMR,
The sum of all the angles is 180°.
65° + 45° + ∠RMQ = 180°
∠RMQ = 70°
In the ΔMNL,
The sum of all the angles is 180°.
65° + 45° + ∠LMN = 180°
∠LMN = 68°
That means,
measure of angle LMQ = 180° - ∠LMN - ∠RMQ
∠LMQ = 180° - 138°
∠LMQ = 42°
Therefore, ∠LMQ = 42°.

Diameter = 14 cm
Radius (r) = ½(14) = 7 cm
height (h) = 10 cm
π = 3.14
Volume of cylinder = πr²h
Plug in the values

A researcher investigates if chocolate affects mood. She recruits college students to take a mood inventory, ingest a quarter pound of chocolate and then complete the mood inventory again. Given the following confidence interval [2.34, 5.41], make a decision about the hypotheses.
And explain why?
A) Reject the null hypothesis and conclude that chocolate affected mood because zero, or no effect, does not fall within the confidence interval.
B) Reject the null hypothesis and conclude chocolate lowers affect because the confidence interval includes small numbers.
C) Fail to reject the null hypothesis because the confidence interval is positive.
D) Fail to reject the null hypothesis and conclude the effect size is small for this study.
Answers
Answer:
A) Reject the null hypothesis and conclude that chocolate affected mood because zero, or no effect, does not fall within the confidence interval
Step-by-step explanation:
The confidence interval could be used as a tool to test an hypothesis on a some certain conditions. When we obtain a confidence interval whose range includes the value 0, we would fail to reject the null hypothesis of such analysis as this upholds the truth of the null hypothesis. However, if the interval does not contain the value 0, we reject the null and claim that there is significant evidence to accept the alternative hypothesis.
Hence, for the confidence interval given [2.34, 5.41], the interval does not contain the value 0, Hence, we reject the null.

28.3 (b)
Step-by-step explanation:
To solve circumference, you will need to use the equation C = 2 *pi* r
for this, we will use 3.14 for pi and the radius is 4.5 so this is how we need to solve it
C= 2 pi (4.5) Solve 2*4.5
C= 9 pi Now we input 3.14 for pi and multiply
C= 9(3.14)
C= 28.26 Now we round to the nearest tenth to get
C=28.3

Step-by-step explanation:
base on my research
The coordinates of the point on the unit circle at angle 225° are [tex]\bold{(-\frac{\sqrt{2} }{2}, -\frac{\sqrt{2} }{2})}[/tex]
What are the coordinates of the point on the circle?The coordinates of the points of the circle x² + y² = r² are [tex](r~cos\theta, r~sin\theta)[/tex]
What is unit circle?"It is a circle with radius 1."
For given example,
We have been given an angle of 225°
⇒ [tex]\theta[/tex] = 225°
We need to find the coordinates of the point on the unit circle at an angle 225°.
Here, r = 1
So, the first coordinate would be,
[tex]r~cos\theta=(1)~cos(225^{\circ})\\\\\Rightarrow r~cos(225^{\circ})=cos(270^{\circ} - 45^{\circ})\\\\\Rightarrow r~cos(225^{\circ})t=cos(270^{\circ}) cos(45^{\circ})+sin(270^{\circ}) sin(45^{\circ})\\\\\Rightarrow r~cos(225^{\circ})=0+(-1)(\frac{1}{\sqrt{2} } )\\\\\Rightarrow r~cos(225^{\circ})=\bold{\frac{-1}{\sqrt{2} }}\\\\\Rightarrow r~cos(225^{\circ})=\bold{-\frac{\sqrt{2} }{2} }[/tex]
Now we find the second coordinate of the point.
[tex]r~sin\theta=(1)~sin(225^{\circ})\\\\\Rightarrow r~sin(225^{\circ})=sin(270^{\circ} - 45^{\circ})\\\\\Rightarrow r~sin(225^{\circ})=sin(270^{\circ}) cos(45^{\circ})-cos(270^{\circ}) sin(45^{\circ})\\\\\Rightarrow r~sin(225^{\circ})=(-1)(\frac{1}{\sqrt{2} } )-0\\\\\Rightarrow r~sin(225^{\circ})=\bold{\frac{-1}{\sqrt{2} }}\\\\\Rightarrow r~sin(225^{\circ})=\bold{-\frac{\sqrt{2} }{2} }[/tex]
Therefore, the coordinates of the point on the unit circle are [tex](-\frac{\sqrt{2} }{2}, -\frac{\sqrt{2} }{2})[/tex]

Yes, there exists one output for

Answers
Answer: Choice D
Yes, there exists one output for every input.
=======================================================
Explanation:
x = input
y = output
For any given x value, we have exactly one and only one y value that pairs up with it. Use the vertical line test. This is where we try to draw a single vertical line through more than one point on the curve. You'll find that no such line can be drawn. Any vertical line only crosses the curve exactly once (corresponding to exactly one output). We say that it passes the vertical line test, and therefore we have a function.
Side note: the curve does not pass the horizontal line test. That means the function is not one-to-one.
