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

The sum of two numbers is 240. If one number is twice the other number, find the two numbers.
Answer:
The sum of two numbers is 240. The larger number is 6 less than twice the smaller. Find the numbers.
----------
Let the smaller be "x" ; Larger is "2x-6"
EQUATION:
x + 2x-6 = 240
3x= 246
x = 82 (smaller)
2x-6 = 158 (larger)

Lucas is selling ribbons to raise money for the Juvenile Diabetes Research Foundation. His expenses include $46 for materials, plus $0.02 per ribbon. If Lucas charges $0.25 per ribbon, how many ribbons does he need to sell to break even
Answer:
He needs to sell 200 ribbons to break even.
Step-by-step explanation:
The break even point is where the expenses are equal to the earnings, so you can write an expression that indicates that Lucas' expenses are equal to his earnings:
46+0.02x=0.25x
Now, you can solve for x to find the answer:
46=0.25x-0.02x
46=0.23x
x=46/0.23
x=200
According to this, the answer is that he needs to sell 200 ribbons to break even.

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

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

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

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.
