Answer:
d. -1
Step-by-step explanation:
the slope is the rise over the run from one point to another.
i hope this helps :)
Each line is 1 unit.
Use the dots A and B
A is located at (-3,3)
B is located at (3,-3)
Slope is the change in y over the change in x
Slope = (-3 -3) / (3 - -3)
Slope = -6/6
Slope = -1
The answer is D -1
Assume that the readings at freezing on a bundle of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. Find the probability of obtaining a reading greater than -0.084°C.
P(Z>-0.084)
Answer:
0.53347
Step-by-step explanation:
We solve the above question using z score formula
z = (x-μ)/σ, where
x is the raw score = -0.084 °C
μ is the population mean = 0 °C
σ is the population standard deviation = 1°C
Z score =x - μ/σ
= -0.084 - 0/1
= -0.084
Probability value from Z-Table:
P(x<-0.084) = 0.46653
P(x>-0.084) = 1 - P(x<-0.084) = 0.53347
The probability of obtaining a reading greater than -0.084°C = P(x > -0.084) =
is 0.53347

Aaron's P.E. class is completing a unit on bowling. So every Friday afternoon for the last three weeks, they have bowled one game at a nearby bowling alley. His scores have been 121, 147, and 96. What would he have to bowl next time in order to have a mean score of 128?
Solution:
Let x represent Aaron's fourth and unknown score. To have a mean of 128, the sum of the four scores would have to be divided by 4. To get that sum by itself, multiply it by 4. You also have to multiply the desired mean of 128 by 4. So the sum of the four scores is equal to 128 times 4.
121 + 147 + 96 + x = 128 ∙ 4
• Substitute in the values of the four scores.
364 + x = 512
• Simplify.
364 - 364 + x = 512 - 364
• Subtract 364 from each side of the equation.
x = 148
• Simplify.
Aaron must score a 148 in order to have a mean score of 128.

standard deviation for town B, 10'.
O C. The interquartile range (IQR) for town A, 20°, is greater than the
IQR for town B, 10°.
D. The interquartile ranges (IQRs) for towns A and B are both 20°.
Answer: C
Step-by-step explanation:
just took test
The interquartile range (IQR) for town A, 20°, is greater than the IQR for town B, 10°. The correct option is C.
What is interquartile range?The interquartile range (IQR) is a measure of the spread of the data's middle 50%. It is defined as the difference between the third and first quartiles (Q1). A larger IQR indicates that the data is spread out more.
Looking at the box plots, we can see that the IQR for town A is the distance between the lower and upper quartiles, which is approximately 30 - 20 = 10 degrees.
The IQR for town B is approximately 45 - 35 = 10 degrees.
So, the interquartile range (IQR) for town A, 20°, is greater than the IQR for town B, 10°.
Option A is incorrect because the IQR for town B exceeds 46o. Option B is incorrect because the box plots do not include the standard deviation. Option D is incorrect because the IQRs for the two towns differ.
Thus, the correct option is C.

Below are two parallel lines with a third line intersecting them.
If you can’t see it the number is 81
Answer:
x° = 81°
Step-by-step explanation:
From the diagram, we have;
Two parallel lines crossed by a common transversal
Therefore, the corresponding angle formed by the transversal and each of the parallel lines are equal
The given angle = 81°
The alternate exterior angle to the given angle = x°
When two parallel lines are crossed by a common transversal, the alternate exterior angles are equal
∴ x° = 81°.

Factor out the GCF from the given polynomial. 10^3 + 16^2 - 18x 10^3 + 16^2 - 18x = (Type your answer in factored form.)
Correct question is;
Factor out the GCF from the given polynomial. 10x³ + 16x² - 18x. (Type your answer in factored form.)
Answer:
GCF = 5x² + 8x - 9
Step-by-step explanation:
The given polynomial is;
10x³ + 16x² - 18x
First thing is to inspect the coefficients and see the greatest number that all three can be divided by evenly without remainder.
The greatest number is 2.
Secondly let's inspect the variables to see what we can factor out.
They all contain x. Thus, x is a factor.
Thus, we will divide each term by 2x to obtain the GCF of the polynomial.
GCF = (10x³/2x) + (16x²/2x) - (18x/2x)
GCF = 5x² + 8x - 9
