The average rate of change of g(x) over the interval [2, 8] is given by
(g (8) - g (2)) / (8 - 2)
In other words, it's the slope of the line through the points (2, g (2)) and (8, g (8)).
Use the definition of the function to evaluate it at the points in the numerator:
• 8 ≥ 4, so using the second piece, g (8) = -0.5(8) + 8 = 4
• 2 < 4, so g (2) = 5(2) + 1 = 11
Then the average rate of change is
(g (8) - g (2)) / (8 - 2) = (4 - 11) / 6 = -7/6

Question 3 (10 points)
(01.07 MC)
The mass of the Eiffel Tower is about 9.16 ⋅ 106 kilograms. The mass of the Golden Gate Bridge is 8.05 ⋅ 108 kilograms. Approximately how many more kilograms is the mass of the Golden Gate Bridge than the mass of the Eiffel Tower? Show your work and write your answer in scientific notation. (10 points)
Answer:
7.96 × 10⁸ kg
Step-by-step explanation:
Step 1: Given data
Mass of the Eiffel Tower (mE): 9.16 × 10⁶ kgMass of the Golden Gate Bridge (mG): 8.05 × 10⁸ kgStep 2: Determine how many more kilograms is the mass of the Golden Gate Bridge than the mass of the Eiffel Tower
To determine this ratio, we need to do the following subtraction.
mG - mE = 8.05 × 10⁸ kg - 9.16 × 10⁶ kg = 7.96 × 10⁸ kg
The Golden Gate Bridge has approximately 7.96 × 10⁸ kg more than the Eiffel Tower.
A beauty supply company has 5 gallons of 20% hydrogen peroxide solution on hand. The
company also has a nearly limitless amount of a solution that contains 30% hydrogen
peroxide. How many gallons of the 30% hydrogen peroxide solution should the company add
to the 20% hydrogen peroxide solution to obtain a mixture that is 23% hydrogen peroxide?
Write your answer as a whole number or as a decimal rounded to the nearest tenth.
Answer:
2.1 gallons
Step-by-step explanation:
Let V = volume of 20 % hydrogen peroxide = 5 gallons, V₁ = volume of 30 % hydrogen peroxide and V₃ = volume of 23 % hydrogen peroxide. So the final volume is V + V₁ = V₂
V₁ + 5 = V₂ (1)
Also, since quantity = concentration × volume,
Let Q = quantity of 20% volume hydrogen peroxide = 0.2V, Q₁ = quantity of 20% volume hydrogen peroxide = 0.3V₁ and Q₂ = quantity of 23% volume hydrogen peroxide = 0.23V₂
So, 0.2V + 0.3V₁ = 0.23V₂
0.2 × 5 + 0.3V₁ = 0.23V₂
1 + 0.3V₁ = 0.23V₂
0.3V₁ - 0.23V₂ = -1 (2)
substituting equation (1) into (2), we have
0.3V₁ - 0.23(V₁ + 5) = -1
expanding the brackets, we have
0.3V₁ - 0.23V₁ + -0.23 × 5 = -1
0.07V₁ - 1.15 = -1
adding 1.15 to both sides, we have
0.07V₁ = -1 + 1.15
0.07V₁ = 0.15
dividing both sides by 0.07, we have
V₁ = 0.15/0.07
= 2.143 gallons
≅ 2.1 gallons to the nearest tenth
So, we need 2.1 gallons of 30 % hydrogen peroxide to obtain a mixture that is 23 % hydrogen peroxide.

put the steps, for changing the formula for sector area of a circle in degrees to the formula for the sector area of a circle in radians, in the correct order
Answer:
see explanation
Step-by-step explanation:
The area (A) of a sector is calculated as
A = area of circe × fraction of circle
= πr² × [tex]\frac{0}{360}[/tex] ← where θ is in degrees
[ note that 360° = 2π radians ], then
A = πr² × [tex]\frac{0}{2\pi }[/tex] ← where θ is in radians
( Cancel π on numerator/ denominator )
A = [tex]\frac{1}{2}[/tex]θr²

Answer:
top down: 2, 4, 1, 7, 6, 5, 3, 8
Step-by-step explanation:
It appears the expected order may be ...
__
Write the formula for a sector area of a circle with central angle, θ, in degrees.
[tex]\textit{Area of a Sector}=\dfrac{\theta}{360^{\circ}}\cdot\pi r^2[/tex]
Replace 360° with 2π radians.
[tex]\dfrac{\theta}{360^{\circ}}=\dfrac{\theta}{2\pi}[/tex]
Replace the angle ratio in degrees with the angle ratio in radians.
[tex]\textit{Area of a Sector}=\dfrac{\theta}{2\pi}\cdot\pi r^2[/tex]
Simplify by cancelling
[tex]\textit{Area of a Sector}=\dfrac{1}{2}\theta r^2[/tex]
Which ordered pair is a solution of this equation? -6x + y = 35 Click on the correct answer. (-1,-7 (-6,-1) (-1,-6) (-7,-1)
Answer:
The ordered pair (-6, -1) is the only solution.
Step-by-step explanation:
-6x + y = 35
Let's plug in the points.
(-1, -7) --> -6(-1) - 7 = 6 - 7 = -1 which does not equal 35
(-6, -1) --> -6(-6) -1 = 35
(-1, -6) --> -6(-1) - 6 = 0 which does not equal 35
(-7, -1) --> -6(-7) - 1 = 41 which does not equal 35

Which of the following describes a correct method for solving the equation: -7/2n + 5= -16 A. Add 5 to both sides, then devide both sides by 2/7. B. Subtract 5 from both sides, then add 7/2 to both sides. C. Add -5 to both sides, then multiply both sides by -2/7. D. Subtract 5 from both sides , then multiply both sides by 7
Answer:
If the use the method ''Add -5 to both sides, then multiply both sides by -2/7'', we can get the value n = 6.
Thus, the correct option is 'C'.
Step-by-step explanation:
Given the equation
[tex]-\frac{7}{2}n+5=-16[/tex]
Let me solve this using the correct method
[tex]-\frac{7}{2}n+5=-16[/tex]
Add -5 to both sides
[tex]-\frac{7}{2}n+5+\left(-5\right)=-16+\left(-5\right)[/tex]
simplify
[tex]-\frac{7}{2}n=-21[/tex]
Multiply both sides by -2/7
[tex]-\frac{7}{2}n\times -\frac{2}{7}=-21\times -\frac{2}{7}[/tex]
simplify
[tex]n=6[/tex]
Therefore, if the use the method ''Add -5 to both sides, then multiply both sides by -2/7'', we can get the value n = 6.
Thus, the correct option is 'C'.

The length of the base of an isosceles triangle is x. The length of a leg is 3x
- 7. The perimeter of the triangle is 63. Find x. *
20
22
11
12
Answer:
Option C: 11 is the correct answer.
Step-by-step explanation:
Given that:
Length of base of isosceles triangle = b = x
The length of leg of triangle = a = 3x-7
Perimeter of triangle = 63
Perimeter of an isosceles triangle is given by
Perimeter = 2a + b
Putting values in the formula
63 = 2(3x-7) + x
63 = 6x-14+x
63 = 7x-14
63+14=7x-14+14
77=7x
7x=77
Dividing both sides by 7
[tex]\frac{7x}{7}=\frac{77}{7}\\x=11[/tex]
The value of x is 11.
Hence,
Option C: 11 is the correct answer.

Bill conducts a study during which he compares two, independent groups and he gets a significance value of .16 (i.e., p=.16). He looks at the means of the groups and sees the Group 1 Mean is 70 and the Group 2 mean is 77. He concludes they are different. (a) Why is Bill wrong? (b) What exactly does his p-value mean, in this instance?
Answer:
P-value is a parameter to compare with the significance level in order to make decisions about rejecting or not the hypothesis
Step-by-step explanation:
When you are developing a hypothesis test, in order to compare two means ( μ₁ and μ₂ ) you have two hypothesis
Null Hypothesis H₀ μ₁ = μ₂
And depending on the problem statement, the alternative hypothesis could be
Alternative Hypothesis Hₐ (1) μ₁ > μ₂
(2) μ₁ < μ₂
(3) μ₁ ≠ μ₂
Now if the result of the test determines that H₀ is rejected you accept in case
(1) μ₁ > μ₂
(2) μ₁ > μ₂
(3) μ₁ ≠ μ₂
In any case, you need a confidence Interval, and as consequence you established a significance level to do your test. These two concept defines the acceptance and the rejection region. Just for instance
CI = 90% means that the acceptance region is 90 %, and at the same time, the rejection area is 10 %. That 10 % will be used as follows,
Case 1 you are developing a one tail-test to the left ( side of the curve )
Case 2 you are developing a one tail-test to the right
Case 3 you are developing a two-tail test ( in that case you need to split α into two equal areas one for each tail.
Now P-value is a tool for decision is an area that you can compare with α to accept or reject H₀.
In our particular case suppose we are testing
H₀ μ₁ = μ₂
Hₐ μ₁ < μ₂
Let´s say CI = 95 then α = 5 % α = 0,05
And we get P-value = 0,16
Then area 0,16 > 0,05 Then we are in the acceptance region
(that condition really implies that z(s) < z(c)

In a study of distances traveled by buses before the first major engine failure, a sample of 191 buses results in a mean of 96,700 miles and a population standard deviation 37,500 miles. Calculate the appropriate test statistic to test the claim that the mean distance traveled before a major engine failure is more than 90,000 miles.
Answer:
The test statistics is [tex]z = 2.47[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 191 \ buses
The sample mean is [tex]\= x = 96 700 \ miles[/tex]
The population standard deviation is [tex]\sigma = 37 500 \ miles[/tex]
The null hypothesis is [tex]H_o : \mu = 90 000[/tex]
The alternative hypothesis is [tex]H_a : \mu > 90 000[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{\= x - \mu }{ \frac{\sigma }{\sqrt{n} } }[/tex]
=> [tex]z = \frac{96700 - 90 000 }{ \frac{37500}{\sqrt{191} } }[/tex]
=> [tex]z = 2.47[/tex]

Ahmed works in a factory his normal rate of pay is £12.00 per hour
When ahmed works on sundays he is paid overtime for each hour.The overtime rate of pay is 1 1/4 times his nomal hourly rate. Lat weekend Ahmed worked 9 hours on Saturday and 6 hours on Sunday. Work out how money he earned during that weekend
Answer:
Ahmed earned £198.00 on that weekend.
Step-by-step explanation:
Given that:
Normal hourly pay = £12.00
Overtime pay = [tex]1\frac{1}{4}[/tex] of normal rate
Overtime pay per hour = [tex]\frac{5}{4}*12[/tex]
Overtime pay per hour = £15.00
Hours worked on Saturday = 9 hours
Amount earned on Saturday = 9*12 = £108.00
Hours worked on Sunday = 6 hours
Amount earned on Sunday = 6*15 = £90.00
Total amount earned on weekend = 108+90 = £198.00
Hence,
Ahmed earned £198.00 on that weekend.
