Unit 3 - Task 3 - (10 points)
Your job is as an administrative assistant for factory operations for a company producing
Whatchamacallits. Your boss hands you the production information for the factory's
production of Whatchamacallits: 3 Whatchas in the first hour, 7 total after hour 2, 11
total after 3 hours and 15 after 4 hours. You are tasked to produce an equation that
models the number of Whatchas produced given the hours worked, and to find the
predicted number of Whatchas produced if the factory can run for 50 hour
uninterrupted.
Find an explicit formula that models the production for the nth term of the sequence
and use the equation to find the 50th term in the sequence. Show your reasoning for
the equation.
The 50th term in the sequence is 199
Arithmetic sequence
The nth term of an arithmetic sequence is expressed as:
Tn = a+ (n - 1)d
where:
a is the first termn is the number of termsd is the common differenceThe sequence formed by the amount of Whatchamacallits produced as;
3, 7, 11, 15...
a = 3
d = 11-7 = 7-3 = 4
Substitute
Tn = 3 + (n-1) * 4
Tn = 3 + 4n -4
Tn = 4n - 1
Hence the explicit formula that models the production for the nth term of the sequence is Tn = 4n - 1
If n = 50
T50 = 4(50) - 1
T50 = 199
Hence the 50th term in the sequence is 199

3. A shipping crate that is shaped like a rectangular
prism is 2.5 feet wide, 2 feet long, and has a height
of 4 feet. What is the volume of the shipping crate?
A. 20 ft
B. 10 ft
C. 8.5 ft
D. None of these
Answer:
A. 20 ft
Step-by-step explanation:
The volume of a right solid such as a rectangular shipping crate is found by multiplying the area of its base by its height. The area of this shipping crate is its length multiplied by its width = 2.5 x 2 = 5 feet. Now, we multiply the area of the base (5) by the height (4) to get 20 feet.
Noam is interested in estimating the average age of the Summer Olympians who have competed since 1980. She randomly selected 24 Olympians, and the result was this list of ages: 16, 17, 19, 19, 19, 20, 20, 20, 21, 21, 21, 21, 22, 22, 23, 23, 24, 25, 26, 27, 28, 29, 30, 32 Construct and interpret a 98% confidence interval for the true mean age of Summer Olympians since the 1980 Olympics. Use the table to determine the appropriate value of t*. Enter in the degrees of freedom and the value of t* (exactly as you see it written in the table). Degrees of freedom =
Using the t-distribution, as we have the standard deviation for the sample, it is found that the 98% confidence interval for the true mean age of Summer Olympians since the 1980 Olympics is (20.6, 24.8). It means that we are 98% sure that the true age of all Olympians is between these two values.
What is a t-distribution confidence interval?The confidence interval is:

In which:
[tex]\overline{x}[/tex] is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.In this problem, with the help of a t-distribution calculator, with a two-tailed significance level of 0.02 and 24 - 1 = 23 degrees of freedom, the parameters are:
[tex]\overline{x} = 22.7, s = 4.15, n = 24, t = 2.5[/tex]

Answer:
[tex]\sf y = 3.17[/tex]
explanation:
[tex]\sf y * y * y = 32[/tex]apply rule: a * a * a = a³
[tex]\sf y^3= 2^5[/tex]changing sides, changes cubic to cubic root
[tex]\sf y = \sqrt[3]{2^5}[/tex]simplify
[tex]\mathrm \huge {y = 2^{\frac{5}{3} }}[/tex]In decimals
[tex]\sf y = 3.174802104[/tex]In two decimal places
[tex]\sf y = 3.17[/tex]Solution:
Note that:
y × y × y = y³ = 32Taking a cube root both sides.
y³ = 32=> ∛y³ = ∛32Writing the prime factors of 32.
=> y = ∛2 x 2 x 2 x 2 x 2Simplifying ∛32
=> y = 2 x ∛2 x 2 = 2 x ∛4Dani wants to spend less than $25 on a birthday present for her friend. If she buys a necklace for $9.50, how many pairs of earrings, e, can she buy for $3.75 each without exceeding her budget? Enter your answer in the box.
Answer:
4
Step-by-step explanation:
Since it costs $3.75 for every earring, multiply e by 3.75 like this: 3.75e
Add 9.5 on top of that since Dani already bought the necklace for $9.50
3.75e + 9.5
This sum has to be less than or equal to 25 because the budget is $25
3.75e + 9.5 ≤ 25
To find e subtract 9.5 from both sides
3.75e + 9.5 ≤ 25
- 9.5 - 9.5
3.75e ≤ 15.5
Divide both sides by 3.75
3.75e/3.75 = 15.5/3.75 = 4.133...
You can't buy 0.133 of an earring, so the max amount of earrings she can buy is 4.
When 21 is subtracted from the square of a number, the result is 4 times the number. Find the negative solution.

x² ← square of number
Equation :-

4 times a number means 4 × x = 4x.

→x² -21 - 4x = 0
→x² - 4x - 21 = 0
→x² + 3x - 7x - 21 = 0
→x(x + 3) - 7x - 21 = 0
→x(x+3) - 7(x + 3) = 0
→(x - 7) (x + 3) = 0

Mid-point: [tex](0,-5)[/tex]
Equation: [tex]y=\frac{7}{3}x-5[/tex]
Step-by-step explanation:
To find the mid-point of AB, simply add up their x and y coordinates and divide by 2 respectively to find their middle point.
[tex](\frac{{x__A}+{x__B}}{2},\frac{{y__A}+{y__B}}{2})[/tex]
[tex](\frac{{-7}+{7}}{2},\frac{{-2}+{(-8)}}{2})[/tex]
[tex](0,-5)[/tex]
To find the perpendicular slope that passes through the mid-point, we need to know the slope between AB first.
Slope of AB: [tex]\frac{{y__2}-{y__1}}{{x__2}-{x__1}}[/tex] = [tex]\frac{{-8}-{-2)}}{{7}-{(-7)}}[/tex] = [tex]\frac{-6}{14}[/tex] = [tex]\frac{-3}{7}[/tex]
Multiplying slopes that are perpendicular with each other always results in -1.
[tex]\frac{-3}{7}*m = -1[/tex]
[tex]m=\frac{7}{3}[/tex]
By the point slope form:
[tex]({y}-{y__1})=m({x}-{x__1})[/tex]
Plug in the coordinates of the mid-point:
[tex]({y}-{(-5)})=\frac{7}{3} ({x}-{0})[/tex]
Equation: [tex]y=\frac{7}{3}x-5[/tex]

(18) What is the equation for a line perpendicular to the line described by the equation -3x + 12y – 7 = 0?
Answer:
Two lines are perpendicular if the product of their slopes equals -1.
In general form, this means that you reverse the coefficients of x and y and negate one of the two.
So the general form of this perpendicular line becomes: 12x + 3y + C = 0, or simplified: 4x + y + C’ = 0.
Now fill in the desired point to find C’: 4*(-2)+5+C’=0 so C’= 3.
The general form of the line becomes 4x + y + 3 = 0

In which:
P(B|A) is the probability of event B happening, given that A happened.[tex]P(A \cap B)[/tex] is the probability of both A and B happening.P(A) is the probability of A happening.In this problem, we have that X and Y are mutually exclusive events, hence [tex]P(X \cap Y) = 0[/tex], hence:

The Perricone family had a water meter reading of 3,970 Tgal last month and 3,973 Tgal this month.
Their water supplier charges a rate of $23.75 per Tgal. What is the estimated annual water cost for
the Perricone family?
The estimated annual water cost for the Perricone family= $1,132,305
Calculation of Estimated water costThe family meter reading for last month = 3,970 Tgal
The family meter reading for next month= 3,973 Tgal
The rate charged by the supplier = $23.75 per Tgal.
There is increase in the meter reading per month by 3Tgal.
To calculate for the monthly cost = 23.75 × 3,970
= $94287.5
Therefore annually= $94287.5 × 12 = $1,131,450
The cost for each monthly increase = 23.75 × 3= $71.25
Therefore annual monthly increase= 71.25× 12= $855
Therefore, the estimated annual water cost for the Perricone family= $1,131,450 + $855
= $1,132,305
