Alexander is a waiter. He gets paid $3.25 per hour plus tips based on his performance. Which expression represents Alexander's salary?
Answer:
f(x) = 3.25x + tips
x = hours
Step-by-step explanation:
Step-by-step explanation: We know how much Alexander gets paid ($3.25) but we don't know how many hours he works. So, the equation will contain a variable.
H will be our variable, it will represent hours.
Therefore, the answer is: f(h) = 3.25 + tips
Definitions:
Variable: A letter representing the unknown.
Equation: A mathecial setence.

Answer:
D
Step-by-step explanation:
By definition, π is defined to be the ratio of a circle's circumference to its diameter. In other words:
[tex]\displaystyle \pi=\frac{C}{d}[/tex]
In fact, if you multiply both sides by the diameter d, you can see that:
[tex]C=\pi d[/tex]
Which is the formula for circumference you've been commonly taught.

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]
35/140= 5/x which number is equal to x?
Answer:

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".

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 magazine publisher is informed that 72% of subscribers last year did not renew their subscriptions. This publisher wants to randomly survey 8% of these past subscribers asking the reason why they did not renew their subscriptions. All of last year's subscribers who did not renew their subscriptions are known collectively as what
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.

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
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

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

Answer:
The median is 6
Step-by-step explanation:
First put the numbers in order: 3,4,4,4,5,7,7,8,9,12
Here, the 5th & 6th terms are 5 &7
So, median = 5+7/2
=12/2
=6
Answer:
6
Step-by-step explanation:
For funding out the median firstly we need to arrange the data in ascending or descending order . Here on arranging the given data in ascending order we have ,
3,4,4,4,5,7,7,8,9,12The median is the middle most observation , in case of odd nos . And the mean of two middlemost observations in case of even nos . Here the number of data is even , and the two middlemost observations are 5 and 7 , so ,
=> Median = x₁ + x₂ / 2
=> Median = 5 + 7/2
=> Median = 12/2
=> Median = 6
Hence the median of the given data is 6 .Twice a number increased by 43 is greater than one-fourth the number increased by 88. Which inequality can be used to determine the number?
2x + 43 > 4x + 88
2x+43>x/4+88
2x+43>x/4-88
2x+43
The required inequality is given as 2x + 43 > x/4 + 88. Option B is correct.
What is inequality?Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
Let the number be x,
According to the question,
Twice a number increased by 43 is greater than one-fourth the number increased by 88.
2x + 43 > x/4 + 88
Thus, the required inequality is given as 2x + 43 > x/4 + 88. Option B is correct.
