The larger of two numbers is 17 more than twice the smaller. When the larger number is divided by the smaller, the quotient is 3 and the remainder is 6. Find the two numbers
Answer:
The numbers described here are 39 and 11.
Step-by-step explanation:
Let's call the numbers a and b, a being the larger. We're told two things:
The larger of the two numbers is 17 more than twice the smaller.
Which we can express as:
a = 2b + 17
When the larger number is divided by the smaller, the quotient is 3 and the remainder is 6
And that can be expressed as:
a = 3b + 6
We can now take those two expressions and, noting that they both define a, we can say that they are equivalent, and solve for b:
2b + 17 = 3b + 6
3b - 2b = 17 - 6
b = 11
With b found, we can now take either of the first expressions, and solve for a:
a = 2b + 17
a = 2(11) + 17
a = 22 + 17
a = 39
Now we can check whether that is correct by plugging it into the other expression and seeing if b still comes to 11:
a = 3b + 6
39 = 3b + 6
3b = 33
b = 11
So we know that the answer is correct.

The value of [x] will be equivalent to x = 3.5.
What is logarithmic function? What is equation modelling? What is a mathematical equation and expression?In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a number [x] to the base [b] is the exponent to which [b] must be raised, to produce [x]. We can write -[tex]y=log_{e} (x)[/tex]
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is the logarithmic equation as
2log(4x) − log(49) = 2
2log(4x) = 2 + log(49)
2{log(4) + log(x)} = 2 + log(49)
{log(4) + log(x)} = {2 + log(49)}/2
log(4) + log(x) = 1 + log(49)/2
log(4) + log(x) = 1.85
log(x) = 1.85 - log(4)
log(x) = 1.25
x = e^(1.25)
x = 3.5 {approx.}
Therefore, the value of [x] will be equivalent to x = 3.5.

At 1 hour the ship traveled 25 miles.
At constant speed, this means every 1 hour the ship travels 25 miles.
The speed would be 25 miles per hour.
Upon studying low bids for shipping contracts, a microcomputer manufacturing company finds that intrastate contracts have low bids that are uniformly distributed between 22 and 29, in units of thousands of dollars. (a) Find the probability that the low bid on the next intrastate shipping contract is below $25,000. (Round your answer to four decimal places.)
Answer:
0.4286 = 42.86% probability that the low bid on the next intrastate shipping contract is below $25,000.
Step-by-step explanation:
A distribution is called uniform if each outcome has the same probability of happening.
The uniform distributon has two bounds, a and b, and the probability of finding a value lower than x is given by:
[tex]P(X < x) = \frac{x - a}{b - a}[/tex]
Uniformly distributed between 22 and 29, in units of thousands of dollars.
This means that [tex]a = 22, b = 29[/tex].
(a) Find the probability that the low bid on the next intrastate shipping contract is below $25,000.
This is P(X < 25). So
[tex]P(X < 25) = \frac{25 - 22}{29 - 22} = 0.4286[/tex]
0.4286 = 42.86% probability that the low bid on the next intrastate shipping contract is below $25,000.

Engineering The equation for the cross section of a spotlight is y+5= 1/2x^2.
measured in inches. The bulb is located at the focus. How far is the bulb from the
Vertex of the cross section?
Answer:
[tex]p=1/2\ or\ 0.5\ inches[/tex]
Step-by-step explanation:
From the question we are told that
Equation of cross section is [tex]y+5= \frac{1}{2x^2}[/tex]
Generally the equation can be rewritten mathematically as
[tex]y+5= \frac{1}{2}x^2[/tex]
[tex]x^2=(y+5)2[/tex]
[tex](x-0)^2=(y-(-5))2[/tex]
Generally the equation of a parabola with vertical axis is mathematically given by
[tex](x - h)2 = 4p(y - k)[/tex]
Therefore comparing equations
[tex](x-0)^2=(y-(-5))2[/tex]
[tex]4p=2[/tex]
[tex]p=2/4[/tex]
The distance from the bulb to the vertex of the cross section is given by

A manufacturing company uses two different machines, A and B, each of which produces a certain item part. The number of defective parts produced by each machine is about 1 percent. Suppose two independent random samples, each of size 100, are selected, where one is a sample of parts produced by machine A and the other is a sample of parts produced by machine B. Which of the following is true about the sampling distribution of the difference in the sample proportions of defective parts?
A The mean is 0 and the distribution is approximately normal
B The mean is 0 and the distribution will not be approximately normal
C The mean is 0.01 and the distribution is approximately normal
D The mean is 0.01 and the distribution will not be approximately normal.
Ε The mean is 1 and the distribution is approximately normal.
Answer:
B: The mean is 0 and the distribution will not be approximately normal
Step-by-step explanation:
It is true that the mean is 0 because it is the difference in the population proportions, 0.01−0.01. However, normality cannot be assumed because the sample sizes are not large enough.
The sample distribution is defined as the probability distribution of a given sample based on statistics.
The correct option is (a).
Given:
The defective parts produced by each machine is 1%.
The sample Size is 100.
Calculate the proportion of the defective parts.
[tex]\dfrac{1}{100}=0.01[/tex]
Thus, the mean of each machine is 0.01.
Now, the mean difference between both machine is 0 and proportion will be normally distributed.

How to solve system of two equations:
First of all, we should get one variable in terms of other variable in one equation and substitute this variable in another equation. And solving that we get two variables value.
If you have two different equations with the same two unknowns in each, you can solve for both unknowns. There are three common methods for solving: addition/subtraction, substitution, and graphing.
Here,
let's consider price of hot dogs = x and price of hamburgers = y
then, 164x + 74y = $706 --- ( 1 )
and 256x + 61y = $884 --- ( 2 )
Now, from eq - 1 we get x = ($706 - 74y) / 164
Substitute this x value in eq - 2,
256($706 - 74y)/164 + 61y = $884
=> $706*256 - 74y*256 + 61y*164 = $884 * 164
=> 180,736-8940y = 144,976
=> 180,736 - 144,976 = 8940y
=> 35,760/8940 = y
=> y = $4.
By substituting in eq - (1) we get x = $2.5
So, The price of hot dog = $2.5

4.A board is 7 3/4 feet in length. How many full sizes pieces of board 1 1/3 feet in length can a carpenter cut from that board of wood
Answer:
5 full pieces
Step-by-step explanation:
Given
[tex]Board\ Length = 7\frac{3}{4}ft[/tex]
[tex]Pieces = 1\frac{1}{3}ft[/tex]
Required
Determine the number of pieces that can be cut from the board
This is calculated by dividing the board length by the length of each piece.
[tex]Number = \frac{Board\ Length}{Pieces}[/tex]
[tex]Number = 7\frac{3}{4} / 1\frac{1}{3}[/tex]
Convert to improper fractions
[tex]Number = \frac{31}{4} / \frac{4}{3}[/tex]
Change / to *
[tex]Number = \frac{31}{4} * \frac{3}{4}[/tex]
[tex]Number = \frac{31*3}{4*4}[/tex]
[tex]Number = \frac{93}{16}[/tex]
[tex]Number = 5.8125[/tex]
Round down to discard the decimal parts
[tex]Number = 5[/tex]
Hence, the carpenter can cut full-sized 5 pieces
11B. Long Beach Towing Company charges $40 plus $5 per mile to
tow a car. The Five-Star Towing Company charges $70 plus $2 per
mile. After how many miles the charges for the two companied will
be the same?
Answer:
The charges will be the same after 10 miles.
Step-by-step explanation:
Long Beach Towing Company:
Charges $40 plus $5 per mile. So after x miles, the charge will be of:
[tex]L(x) = 40 + 5x[/tex]
Five-Star Towing Company:
Chargers of $70 plus $2 per mile. So after x miles, the charge will be of:
[tex]F(x) = 70 + 2x[/tex]
After how many miles the charges for the two companied will be the same?
This is x for which:
[tex]L(x) = F(x)[/tex]
So
[tex]40 + 5x = 70 + 2x[/tex]
[tex]5x - 2x = 70 - 40[/tex]
[tex]3x = 30[/tex]
[tex]x = \frac{30}{3}[/tex]
[tex]x = 10[/tex]
The charges will be the same after 10 miles.

Answer:

Step-by-step explanation:
The area of a triangle can be given as [tex]\frac{1}{2}\cdot b \cdot h[/tex]. Notice that a base of the triangle is given as 4 units, and the height is marked as 5 units. We know that the segment marked as 5 units is the height of the triangle because it forms a [tex]90^{\circ}[/tex] with the segment marked as 4 units and meets a vertex of the triangle.
Therefore, the area of the triangle is:
