Answer and explanation:
First Prof. Murphy has to choose between two alternatives: gummy candy or licorice nibs
To find total choices, we only need to multiply number of sizes for each alternative and then add totals for each alternative together
So if Prof Murphy chooses gummy candy. He has sizes= 5 choices and types =3 choices, therefore he has 5×3= 15 choices for gummy candy
If he chooses licorice nibs, he has sizes = 2 choices and types= 2 choices, therefore he has 2×2= 4 choices for licorice nibs
Total choices: 15+4=19
He has 19 different options for selecting candy.
Since while selecting candy for students in his class, Professor Murphy must choose between gummy candy and licorice nibs, and gummy candy packets come in five sizes, while packets of licorice nibs come in two, and if he chooses gummy candy, he must select gummy bears, gummy worms, or gummy dinos, while if he chooses licorice nibs, he must choose between red and black, to determine how many choices does he have, the following calculation must be performed:
Number of sizes x number of options = X Gummy candy = 5 x 3 = 15 Licorice nibs = 2 x 2 = 4 15 + 4 = 19
Therefore, he has 19 different options for selecting candy.

A desk is on sale for $438, which is 27% less than the regular price.
What is the regular price?
Answer: $600
Step-by-step explanation:
The sale price is 27% less means $438 is equal to 73% of the original price. So to calculate the original price:
Original price = (438÷73) X 100
$ 600
The regular price of the desk is $600.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
Let's say the regular price of a desk = x
Then,
27% of x ⇒ 27 × x / 100 = 0.27x
So,
x - 0.27x = 438
0.73x = 438
x = 600
Hence "The regular price of the desk is $600".

Jane and five friends go on a camping holiday together for a week,
The 6 friends will share the costs of the holiday equally.
Here are the costs of the holiday.
£216 for 6 return coach tickets
£404 for the campsite
£316 for hire of a tent for a week
Work out how much Jane has to pay for her share of the costs.
Answer:
Jane's share of the cost is £156
Step-by-step explanation:
Since the cost is to be shared equally amongst the 6 friends, to get the amount to be paid by Jane, we must work out the total cost to be incurred first.
Total cost = £216 + £404 + £316
= £936
Since there are 6 friends willing to bear this cost equally, the amount to be paid by Jane
= £936/6
= £156

Select the correct answer. The supply and demand curves for a product line of bicycles are shown. Approximately where is the equilibrium point? A. (93,268) B. (132,220) C. (180,355) D. (220,115)
Answer:
B. (132,220)
Step-by-step explanation:
The equilibrium point is the point where the quantity demanded is equal to the quantity supplied.
The equilibrium point (equilibrium price and equilibrium quantity) occur at the point where the supply and demand curves cross each other.
From the graph, we can see that the supply and demand curve cross each other at point. The equilibrium point is this point and it is gotten by tracing to the vertical and horizontal axis.
The equilibrium point is at (132, 220).
Hence the equilibrium price = $132 and equilibrium quantity = 220

Solve: 4x + 6 = 8x - 18
Answer:
x=-3
Step-by-step explanation:
4x+6=8x+18
We simplify the equation to the form, which is simple to understand
4x+6=8x+18
We move all terms containing x to the left and all other terms to the right.
+4x-8x=+18-6
We simplify left and right side of the equation.
-4x=+12
We divide both sides of the equation by -4 to get x.
x=-3

Answer:
Sampling frame
Explanation:
A sampling frame is the source where the researcher draws his samples from. In other words, a sampling frame is like the population where the researcher gets samples for his investigation. In the above example, we are told the researcher wants to know why the 72% that subscribed last year didn't subscribe this year. He draws a sample of 8% from the 72% that he is trying to study, therefore the 72% are the sampling frame from where he gets his sample.

Refer to the previous exercise. The researchers wanted a sufficiently large sample to be able to estimate the probability of preferring the new analgesic to within 0.08, with confidence 0.95. If the true probability is 0.75, how large a sample is needed to achieve this accuracy
Answer:
The large sample n = 117.07
Step-by-step explanation:
Step(i):-
Given that the estimate error (M.E) = 0.08
The proportion (p) = 0.75
q =1-p = 1- 0.75 =0.25
Level of significance = 0.05
Z₀.₀₅ = 1.96≅ 2
Step(ii):-
The Marginal error is determined by
M.E = [tex]\frac{Z_{0.05} \sqrt{p(1-p)} }{\sqrt{n} }[/tex]
[tex]0.08 = \frac{2 X \sqrt{0.75(1-0.75)} }{\sqrt{n} }[/tex]
Cross multiplication , we get
[tex]\sqrt{n} = \frac{2 X \sqrt{0.75(1-0.75)} }{0.08 }[/tex]
√n = [tex]\frac{2 X0.4330}{0.08} = 10.825[/tex]
squaring on both sides , we get
n = 117.07
Final answer:-
The large sample n = 117.07

A huge trucking firm determines that its fleet of trucks averages a mean of 12.4 miles per gallon with a standard deviation of 1.2 miles per gallon on cross-country hauls. The distribution of miles per gallon is approximately normally distributed. What is the probability that a randomly selected truck averages fewer than 10 miles per gallon
Answer:
[tex]P(x<10miles)=0.023[/tex]
Step-by-step explanation:
From the question we are told that
Sample mean [tex]\=x=12.4[/tex]
Standard deviation [tex]\sigma=1.2miles\ per\ gallon[/tex]
Probability of [tex]P(x<10miles)[/tex]
Generally the equation for [tex]P(x<10miles)[/tex] is mathematically given as
[tex]P(x<10miles)=(\frac{10-12.4}{1.2})[/tex]
[tex]P(x<10miles)=0.023[/tex]
Therefore The probability that a randomly selected truck averages fewer than 10 miles per gallon
[tex]P(x<10miles)=0.023[/tex]
Find the indicated term of each sequence by repeatedly multiplying the first term by the common ratio.
Enter your answer to 5 decimal places if necessary. Use a calculator.
A
-50, 35, -24.5,..;5th term
The 5th term of the sequence is 70
Answer:
Step-by-step explanation:
The first term here is -50 and the common ratio is 0.70. Note that the second term is 0.70(50) = 35.
The formula a(n) = a(0)*r^(n -1) becomes a(n) = -50*0.70^(n -1), and so
the 5th term is a(5) = -50*0.70^4 = -12.005
