Find the rate of change for each interval solve 2
we will use the next formula to find the rate of change of the given interval
\(r=\frac{f(b)-f(a)}{b-a}\)in our case
a=-3
b=6
\(f(-3)=10\log (-3+4)+2=2\)\(f(6)=10\log (6+4)+2=12\)then we substitute the values in the formula
\(r=\frac{12-2}{6-(-3)}=\frac{10}{6+3}=\frac{10}{9}\)The average rate of change is 10/9=1.11
The z score associated with the highest 10% is closest to
a. .0398
b. .5398
c. 1.28
d. -1.28
The z score associated with the highest 10% is closest to: option (c) 1.28
-To find the z score associated with the highest 10%, first determine the percentage that corresponds to the lower 90%, since the z score table typically represents the area to the left of the z score.
- Look up the 0.90 (90%) in a standard normal distribution (z score) table, which will give you the corresponding z score.
-The z score closest to 0.90 in the table is 1.28, which corresponds to the highest 10% of values.
Therefore, the z score associated with the highest 10% is closest to 1.28.

What is mZHLG?
Enter your answer in the box.
(25m 22)
(9)
Answer:
\(\angle HLG=18 \textdegree\)
Step-by-step explanation:
The sum of the angles in the top quadrant must add up to 90º.
We are given
\(25m+22\) and \(9m\)
The sum of those must equal 90.
Therefore we can write
\((25m+22)+(9m)=90\)
Rearrange and remove the parenthesis.
\(9m+25m+22=90\)
Add \(9m\) and \(25m\).
\(34m+22=90\)
Subtract 22 form both sides of the equation.
\(34m=68\)
Divide both sides of the equation by 34.
\(m=2\)
Now we can evaluate \(\angle HLG\).
\(\angle HLG=9m\\m=2\\\angle HLG=9*2\\\angle HLG=18 \textdegree\)

Which is the graph of the equation ?
A coordinate plane with a line passing through (0, negative 3), (2, 0), and (4, 3).
Which equation represents the graphed function?
–3x + 2 = y
–x + 2 = y
x – 3 = y

Suppose the National Transportation Safety Board (NTSB) wants to examine the safety of compact cars, midsize cars, and full-size cars. It collects a sample of three for each of the treatments (cars types). Using the hypothetical data provided below, test whether the mean pressure applied to the driver’s head during a crash test is significantly different for each type of car. Use α = 5% to hand calculate and check your work in SPSS.
Compact Cars Midsize Cars Full-Size Cars
6 4 9
6 4 8
7 5 5
Answer:
The mean pressure applied to the driver’s head during a crash test is not significantly different for each type of car.
Step-by-step explanation:
A one-way ANOVA is used to test whether there is significant difference between the means for more than two groups.
In this case we need to test whether the mean pressure applied to the driver’s head during a crash test is significantly different for each type of car.
So, a one-way ANOVA would be used.
The hypothesis can be defined as follows:
H₀: There is no difference between the means, i.e. \(\mu_{1}=\mu_{2}=\mu_{3}\)
Hₐ: There is a significant difference between the means, i.e. at least one of the mean is different.
Use MS-Excel to perform the ANOVA test.
Go to Data – Data Analysis – Anova: Single Factor
Enter the data and enter Alpha as 0.05.
Press OK.
The output is attached below.
The F-test statistic value is, F = 5.143.
The p-value of the test is, p-value = 0.072.
Decision Rule:
If the p-value of the test is less than the significance level then the null hypothesis will be rejected.
p-value = 0.072 > α = 0.05
The null hypothesis will not be rejected.
Conclusion:
The mean pressure applied to the driver’s head during a crash test is not significantly different for each type of car.

Given the expression that models the tip amount for a total bill of $102:
\(0.25\mleft(102-x\mright)\)You know that "x" represents the dollar amount of the tax.
You also know that Mr. Jaxon tips $23.50.
Therefore, knowing all that information, you can set up the following equation to represent that situation:
\(23.50=0.25\mleft(102-x\mright)\)Now you have to solve for "x" in order to find its value:
\(\begin{gathered} 23.50=(0.25)(102)-(0.25)(x) \\ \\ 23.50=25.5-0.25x \end{gathered}\)\(\begin{gathered} 23.50-25.5=-0.25x \\ \\ -2=-0.25x \end{gathered}\)\(\begin{gathered} \frac{-2}{-0.25}=x \\ \\ x=8 \end{gathered}\)Hence, the answer is:

melia, Luis, Shauna, and Clarence used different approaches to solve the inequality
7.2b + 6.5 > 4.8b – 8.1.
Amelia started by subtracting 7.2b from both sides to get 6.5 > –2.4b – 8.1.
Luis started by subtracting 4.8b from both sides to get 2.4b + 6.5 < – 8.1.
Shauna started by subtracting 6.5 from both sides to get 7.2b > 4.8b – 14.6.
Clarence started by adding 8.1 to both sides to get 7.2b + 14.6 > 4.8b.
Which student’s first step was incorrect, and why?
Amelia’s, because the variable term must be isolated on the left side
Luis’s, because he flipped the inequality sign when he subtracted
Shauna’s, because she did not apply the subtraction property of equality properly
Clarence’s, because the terms he added together were not like terms
The first step in correct of Luis’s, because he flipped the inequality sign when he subtracted.
What are Linear Inequalities?Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.
Given inequality is 7.2b + 6.5 > 4.8b – 8.1.
We can solve this inequality in many ways.
As Amelia, we can subtract 7.2b from both sides and get 6.5 > –2.4b – 8.1.
As Shauna after subtracting 6.5 from both sides, we get 7.2b > 4.8b – 14.6.
As Clarence, after adding 8.1 to both sides, we get, 7.2b + 14.6 > 4.8b.
Luis started by subtracting 4.8b from both sides to get 2.4b + 6.5 < – 8.1.
This is incorrect because the inequality symbol is flipped. It is not needed to flip the inequality symbol in subtraction.
Hence the incorrect first step is Luis’s, because he flipped the inequality sign when he subtracted.

can you make two triangles that are not congruent that have three pairs of congruent angles?
if two triangles have three pairs of congruent angles, then they must be congruent to each other by the Angle-Angle-Angle (AAA) congruence theorem, and thus cannot be non-congruent.
No, it is not possible to make two triangles that are not congruent and have three pairs of congruent angles. This is because if two angles of a triangle are congruent, then the third angle must also be congruent by the Angle Sum Theorem, which states that the sum of the angles in a triangle is always 180 degrees. If two triangles have three pairs of congruent angles, then all three angles in each triangle are congruent, meaning they have the same measure. However, this does not guarantee that the sides of the triangles are congruent. In order for two triangles to be congruent, they must have the same angle measures as well as the same side lengths. Therefore, if two triangles have three pairs of congruent angles, then they must be congruent to each other by the Angle-Angle-Angle (AAA) congruence theorem, and thus cannot be non-congruent.
