Question #2, show how you know
Answer: Choice B is correct.
==================================================
Explanation:
We are told that the derivative function f ' (x) is positive for all real numbers x. This means that f(x) is increasing for all real numbers. An increasing function goes uphill as you move from left to right. This rules out choices C and D.
We're also told that the integral of f(t), from t = 4 to t = 7, is equal to 0. Because f(x) is increasing, this must mean that some portion of f(x) is below the x axis and some portion is above the x axis when focused on the interval of [tex]4 \le x \le 7[/tex]. This allows us to rule out choice E since there are no portions that are below the x axis here.
At this point, the answer is between A and B. We can rule out choice A for similar reasoning we did with choice E. This time, there is no portion that is above the x axis. We need a negative area (below the x axis) to counterbalance with a positive area (above the x axis) so that the two areas cancel out and add to 0. That doesn't happen with choice A.
The only thing left is choice B so that must be the answer. We have a portion below the x axis and a portion above it, so it's possible that these two areas cancel out to add to 0. Since we don't know the actual f(x) function, it's impossible to tell whether that happens or not.

If a Variable has a normal distribution with mean 30 and standard deviation 5 find the probability that the variable will be between 25 and 37.
A. 0.77
B. 80
0.72
0.75
Answer:
P(25 < x < 37) = 0.77
Step-by-step explanation:
Given - If a Variable has a normal distribution with mean 30 and standard deviation 5
To find - find the probability that the variable will be between 25 and 37.
Proof -
Given that,
Mean, μ = 30
S.D, σ = 5
Now,
[tex]z = \frac{x-\mu}{\sigma}[/tex] ~ N(0,1)
Now,
P(25 < x < 37)
= [tex]P(\frac{25 - 30}{5} < z < \frac{37 - 30}{5} )[/tex]
= P(1 < z < 1.4)
= P(z < 1.4) - P(z < -1)
= 0.9192 - 0.1587
= 0.7605
≈ 0.77
∴ we get
P(25 < x < 37) = 0.77

Assuming there are no leap years, what would the total 3-year cost be for a laptop that has an average lifespan of 10 years, when you purchased it for $780 and the daily cost to use it is $0.36
A $394.20
B$565.92
C$78.00
D$S1174 20
Answer:
Step-by-step explanation:
The total cost for the laptop for 3 years is $1174.20.
What is Multiplication?Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.
a × b means that a is added to itself b times or b is added to itself a times.
Given that,
Cost of the laptop when purchased = $780
Daily cost = $0.36
Number of days in 3 years = 3 × 365 = 1095 days
Cost for the laptop for 3 years = 1095 × $0.36
= $394.20
Total 3 year cost = $394.20 + $780
= $1174.20
Hence the total cost for the laptop is $1174.20.

X - 3y – Z=-9
-2x + y + 2z = 3
2x + y + 3z = 8
Answer:
x = 1 y = 3 z = 1
Step-by-step explanation:
(1) x - 3y - z = -9 (2) -2x + y + 2z = 3 (3) 2x + y + 3z = 8
2x(1) 2x - 6y - 2z = -18 (2) -2x + y + 2z = 3
- 5y = -15 2y + 5z = 11
y = 3 2(3) + 5z = 11
6 + 5z = 11
5z = 5
z = 1
x - 3(3) - 1 = -9
x - 9 - 1 = -9
x - 10 = -9
x = 1

Answer:
A. 55°
Step-by-step explanation:
Complementary angles are angles that add up to give us 90°.
Since <A and <B are complementary angles, it implies that:
m<A + m<B = 90°
If m<A = 35°, therefore:
35° + m<B = 90°
Subtract 35° from each side
m<B = 90° - 35°
m<B = 55°

Upon retirement your mother received E 500, 000 lump sum. She expect to live for the next 15 years and will only depend on the retirement fund for income. Her bank offers 12% interest per annum. Advise your mother on how much she should withdraw from her bank at the end of each year for the duration of the desired life span? [10 marks]
Answer:
You'll need to look at the attached formula.
Annual Payout = 500,000 * .12 * (1.12)^15 / [(1.12)^15 -1]
Annual Payout = 500,000 * .12 * 5.4735657593 / [ 5.4735657593 -1]
Annual Payout = 500,000 * .12 * 5.4735657593 / [4.4735657593]
Annual Payout = 60,000 * 5.4735657593 / [4.4735657593]
Annual Payout = 73,412.12

A bottler of drinking water fills plastic bottles with a mean volume of 993 milliliters (mL) and standard deviation of 4 mL. The fill volumes are normally distributed. What proportion of bottles have volumes between 991 mL and 997 mL?
Answer:
52.38%
Step-by-step explanation:
P(991<X<997) = normalcdf(991,997,993,4) = 0.5328, therefore, about 52.38% of the bottles have volumes between 991 mL and 997 mL
The required proportion of bottles have volumes between 991 mL and 997 mL is 53.28%
Given that,
A bottler of drinking water fills plastic bottles with a mean volume of 993 milliliters (mL),
And standard deviation of 4 ml. The fill volumes are normally distributed.
We have to determine,
What proportion of bottles have volumes between 991 mL and 997 mL.
According to the question,
Mean of the drinking bottle = 993ml
[tex]\mu = 993[/tex]
And standard deviation of = 4 mL
[tex]\sigma = 4[/tex]
The proportion of bottles have volumes between 991 mL and 997 mL is,
[tex]= P (991<X<997) \\\\= P ( \dfrac{991-993}{4} <X < \dfrac{997-993}{4}) \\\\P( -0.5 < X < 1) = 0.5328 = 53.28\ percent[/tex]
Hence, The required proportion of bottles have volumes between 991 mL and 997 mL is 53.28%.
