Answer:
Step-by-step explanation:
Given the expression 2y+13=y+5
To get the value of y, we willow the following steps:
Subtract 2y to both sides:
2y+13-2y = y+5-2y
13 = -y+5
subtract 5 from both sides:
13-5 = -y+5-5
8 = -y
-y = 8
multiply both sides by -1
-(-y) = -8
y = -8
Hence the value of y = -8 not -14
So NO,if you continue to solve, y would not be -14

A boat capsized and sank in a lake Based on an assumption of a mean weight of 131 lb, the boat was rated to carry 60 assengers (s the load lin was 7,860 lb).
After the boat sank, the assumed mean weight for similar boats was changed from 131 lb to 173 lb Complete parts a and below.
a. Assume that a similar boat is loaded with 60 passengers, and assume that the weights of people are normally distributed with a mea of 176 1 lb end a standard

A total of $20,000 is to be invested, some in bonds and some in certificates of deposit (CDs). If the amount invested in bonds is to exceed that in CDs by $3000, how much will be invested in each type of investment?
Answer:
$8,500 in CDs; $11,500 in bonds
Step-by-step explanation:
Let c = amount invested in CDs.
Let b = amount invested in bonds.
"A total of $20,000 is to be invested, some in bonds and some in certificates of deposit (CDs)."
From the total investment, we get this equation.
c + b = 20000
"If the amount invested in bonds is to exceed that in CDs by $3000"
From the details of the amounts, we get this equation.
b = c + 3000
We have a system of equations in two unknowns.
c + b = 20000 Eq. 1
b = c + 3000 Eq. 2
Since Eq. 2 is already solved for b, we will use the substitution method to solve the system of equations.
Substitute b in Eq. 1 with c + 3000.
c + c + 3000 = 20000
2c + 3000 = 20000
2c = 17000
c = 8500
Now substitute c = 8500 in Eq. 2 and solve for b.
b = c + 3000
b = 8500 + 3000
b = 11500
Answer: $8,500 in CDs; $11,500 in bonds
Suppose that E and F are points on the number line. If EF=5 and F lies at -3, where could E be located?
Answer:
There are two possible locations. E could be located in either -8 or 2.
Step-by-step explanation:
The number line is a one-dimensional graphing model for real numbers, in which each element is represented by points. Under this system, there are two directions:
[tex]-x[/tex] - Left semiaxis that corresponds to negative real numbers.
[tex]+x[/tex] - Right semiaxis that corresponds to positive real numbers.
Both semiaxis are divided by origin, which represents the real number zero.
Let E and F points on the number. If we know that [tex]F = -3[/tex] and [tex]EF = 5[/tex], there are two choices for the location of E. That is:
[tex]E_{1} = F+EF[/tex]
[tex]E_{1} = -3+5[/tex]
[tex]E_{1} = 2[/tex]
[tex]E_{2} = F-EF[/tex]
[tex]E_{2} = -3 -5[/tex]
[tex]E_{2} = -8[/tex]
There are two possible locations. E could be located in either -8 or 2.

An airline promotion to business travelers is based on the assumption that two-thirds of business travelers use a laptop computer on overnight business trips. a. State the hypotheses that can be used to test the assumption. H 0: p Select H a: p Select b. What is the sample proportion from an American Express sponsored survey that found 355 of 546 business travelers use a laptop computer on overnight business trips
Answer:
a
The null hypothesis is [tex]H_o : p = 0.67[/tex]
The alternative hypothesis is [tex]H_a : p \ne 0.67[/tex]
b
The sample proportion is [tex]\^ p = 0.65[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 546
The number of people that use a laptop overnight is [tex]k = 355[/tex]
The population proportion is [tex]p = \frac{2}{3} = 0.67[/tex]
Generally
The null hypothesis is [tex]H_o : p = 0.67[/tex]
The alternative hypothesis is [tex]H_a : p \ne 0.67[/tex]
Gnerally the sample proportion is mathematically represented as
[tex]\^ p = \frac{ k}{n}[/tex]
=> [tex]\^ p = \frac{ 355}{546}[/tex]
=> [tex]\^ p = 0.65[/tex]

Fran is making pancakes. The recipe for the pancakes calls for 1/8 teaspoon of salt for every 3/4 cup of flour. Fran makes an amount of pancakes that needs 18 cups of flour. How much salt, in teaspoons, does Fran need to use for the pancakes?
Answer:
3 teaspoon
Step-by-step explanation:
If for every 3/4 cup of flour we will need 1/8 teaspoon of salt, then:
1/8 teaspoon = 3/4 cup of flour
To get the amount of teaspoon needed for 18cups we will say:
x teaspoon = 18 cups
Solving both equalities for x:
1/8 teaspoon = 3/4 cup of flour
x teaspoon = 18 cups
Cross multiply
3/4 * x = 18 * 1/8
3x/4 = 18/8
cross multiply again
3x*8 = 4*18
24x = 72
x = 72/24
x = 3
Hence Fran needs 3 teaspoon of salt fir 18cups of flour
The numbers of regular season wins for 10 football teams in a given season are given below. Determine the range, mean, variance, and standard deviation of the
population data set
2, 9, 15, 4, 12, 9, 13, 6, 3, 10
The range is 13.
(Simplify your answer.)
The population mean is 8.3.
(Simplify your answer. Round to the nearest tenth as needed.)
The population variance is
(Simplify your answer. Round to the nearest hundredth as needed.)
Answer:
Range = 13
Mean = 8.3
Variance = 17.61
Step-by-step explanation:
Given the population dataset :
2, 9, 15, 4, 12, 9, 13, 6, 3, 10
1.) Range : (maximum - minimum)
Maximum = 15 ; minimum = 2
Range = (15 - 2) = 13
2.) population mean (μ) :
μ = ΣX / n
n = sample size
μ = (2 + 9 + 15 + 4 + 12 + 9 + 13 + 6 + 3 + 10) / 10
μ = 83 / 10
μ = 8.3
3.) Population variance (s²)
Σ(x - μ)² / n
=[(2 - 8.3)^2 + (9 - 8.3)^2 + (15 - 8.3)^2 + (4 - 8.3)^2 + (12 - 8.3)^2 + (9 - 8.3)^2 + (13 - 8.3)^2 + (6 - 8.3)^2 + (3 - 8.3)^2 + (10 - 8.3)^2] / 10
s² = 176.1 / 10
s² = 17.61

point Q was rotated about the origin (0,0) by 180
Answer:B
Step-by-step explanation:
The coordinates of the image of the rotation of the point Q is:
Q' = (4, 2)
What is the image of the rotation?
We can see that the original coordinates of point Q are (-4, 0).
If we apply a rotation of 180° about the point (0, 0), it is equivalent to a reflection around the y-axis.
It only changes the sign of the x-component.
Then the image of the rotation is:
Q' = (4, 0)

What are the coordinates of the x-intercept of the line 2x-5y=10 ?
Answer:
(5, 0) is the x intercept.
Step-by-step explanation:
Given equation of the line is 2x - 5y = 10
For y-intercept of the line we find the value of y by substituting x = 0 in the given equation.
Similarly, for x-intercept we will substitute the value y = 0 and find the value of x.
2x - 5(0) = 10
2x = 10
x = 5
Therefore, y-intercept of the given line is (5, 0).
Sven buying 3 1/3 pounds of wood. The wood costs 1.60 per pound. How much did Sven pay?
Answer:
$5.33
Step-by-step explanation:
If there are 3 1/3 lbs of wood and it's $1.60 per lb, then:
Turn the mixed number into an improper fraction first:
3 1/3 = 3/3 + 3/3 + 3/3 + 1/3
= 10/3
Then, turn 1.60 into an improper fraction too:
1.6 = 1 6/10
= 1 3/5
= 5/5 + 3/5
= 8/5
Then—letting x represent the number of lbs:
8/5x = 8/5 × 10/3
= (8 × 10)/(5 × 3)
= 80/15
= 16/3
To put this in dollar/decimal form, simplify:
16 ÷ 3 = 5.3333333 . . .
≈ $5.33

picture and frame.
Type your simplified answer for the area of the picture and frame along with your
work in the box below. To receive any partial credit, you must include all your work.
Answer:
Ok so the area of the frame is 18*12 = 216cm^2
Let’s suppose the width of the frame is x
The total area (painting and frame) is (2x+18)(2x+12) and this is equal to 432
4x^2 + 60x + 216 = 432
4x^2 + 60x - 216 = 0
x^2 + 15x - 54 = 0
(x+18)(x-3) = 0
Therefore x = {-18,3}
Since width of the frame has to be positive, the width has to be 3cm Step-

One package of blackberries costs $3. How many packages of blackberries can you buy for $15?
Answer:
5 packages
Step-by-step explanation:
One package of blackberries cost $3
Let x represent the number of packages that will cost $15
1 = $3
x= $15
3x= 15
Divide both sides by the coefficient of x which is 3
3x= 15/3
x= 5
Hence 5 packages of blackberries will cost $15
