Find the solution of the system of equations . - 5x + 9y = 11 x - 3y = - 7
how do i solve this
Answer:
Solution: x=5, y=4
Step-by-step explanation:
System of Equations
We need to solve:
- 5x + 9y = 11
x - 3y = - 7
There are several ways to solve a system of linear equations. We'll take advantage of the second equation since it has the x with coefficient 1 and solve it for x:
x = - 7 + 3y
Now replace it into the first equation:
- 5(- 7 + 3y) + 9y = 11
Operate:
35 - 15y + 9y = 11
Simplify:
35 - 6y = 11
Rearrange:
- 6y = 11 - 35 = -24
Solve:
y = -24 / -6
y = 4
Finally, since
x = - 7 + 3y
x = - 7 + 3*4
x = - 7 + 12
x = 5
Solution: x=5, y=4
At a fixed operating setting, the pressure in a line downstream of a reciprocating compressor has a mean value of 12.0 bar with a standard deviation of 1.0 bar based on a very large data set obtained from continuous monitoring.
Required:
What is the probability that the line pressure will exceed 13.0 bar during any measurement?
Answer:
P [ Z > 13 ] = 0,1587 or P [ Z > 13 ] = 15,87 %
Step-by-step explanation:
The probability that the line pressure will exceed 13.0 bar is:
P [ Z > 13 ] = 1 - P [ Z ≤ 13]
And P [ Z ≤ 13] will be find in z table for z (score) =
z ( score) = ( Z - μ₀ ) / σ
z (score) = (13 - 12 )/1
Then from z-table we find
P [ Z ≤ 13] = 0,8413
Finally
P [ Z > 13 ] = 1 - P [ Z ≤ 13]
P [ Z > 13 ] = 1 - 0,8413
P [ Z > 13 ] = 0,1587 or P [ Z > 13 ] = 15,87 %
Lamark goes to a bowling alley to test his belief that rolling a bowling ball slowly will result in knocking down more pins. He gently rolls his bowling ball towards the bowling pins lined up at the end of the lane. The bowling ball stops in the middle of the lane without striking the pins. Which statement below best explains what happened?
Answer: Ball's kinetic energy became potential energy
Step-by-step explanation:
There are no options attached but this should be along the lines of what happened.
Kinetic energy refers to energy that an object has as a result of it moving whilst potential energy is the opposite and is energy that an object stores within itself due to several factors whilst it is not in motion.
The ball was initially in motion which means that it had kinetic energy but as the ball was slowing down, this energy was gradually converted to potential energy until the balls came to a standstill.
Determine whether the given relations are functions.
Answer:
Yes, this relation is a function.
Step-by-step explanation:
It is a function because every input (left side) only has one output (right side). It doesn't matter if an output has multiple inputs. As long as an input has only one output, it is a function
Ex: 3 = 8 & 7 NOT an input

Given a right triangle with sides of length a, b, and c and area a²+b²-c², find c/b, the ratio of the legs of the right triangle.
Answer:
4
Step-by-step explanation:
Looking at the sketch we can formulate 2 equations:
Pythag: [tex]b^{2} +c^{2} =a^{2}[/tex]
Area of triangle= [tex]\frac{1}{2} bc[/tex]
But area also = [tex]a^{2} +b^{2} -c^{2}[/tex] (from the question)
Therefore [tex]\frac{1}{2} bc[/tex] = [tex]a^{2} +b^{2} -c^{2}[/tex]
But we can sub in the expression for [tex]a^{2}[/tex] from pythag. ([tex]b^{2} +c^{2} =a^{2}[/tex])
[tex]\frac{1}{2} bc= b^{2} +c^{2} +b^{2} -c^{2}[/tex]
[tex]\frac{1}{2} bc=2b^{2}[/tex]
[tex]bc=4b^{2}[/tex]
[tex]c=4b[/tex]
[tex]c/b= 4b/b=4[/tex]

How many solution does 8(3x-6=6(x+8) have
Answer:
Step-by-step explanation:
at most 1.
8(3x - 6) = 6(x + 8)
24x - 48 = 4x + 48 Subtract 4x
24x - 4x - 48 = 4x -4x + 48 Combine
20x - 48 = 48 Add 48 to both sides.
20x = 96 divide by 20
x = 96/20
x = 4.8

You plan on using cost-based pricing. The cost of your product is $10, and you are planning a 30% mark-up. What should the price of your product be?
Answer:
Selling price= $13
Step-by-step explanation:
Giving the following information:
The cost of your product is $10, and you are planning a 30% mark-up.
The price of the product is calculated by adding to the manufacturing costs a predetermined percentage.
Selling price= 10*1.3
Selling price= $13
Based on the cost of the product and the mark-up, the price of the product will be $13.
Price of productThis can be fund using the formula:
= Cost of product x ( 1 + markup percentage)
Solving gives:
= 10 x ( 1 + 30%)
= 10 x 1.3
= $13
In conclusion, the product would be $13.

The manager of a bakery states in a report that the average value of customer transactions is greater than $13.65. A random sample of 38 transactions was taken, yielding an average of $14.92 with a standard deviation of $5.51. (a) Which hypotheses should be used to show the manager's claim is correct? H0: p = 14.92 vs. Ha: p > 14.92 H0: p = 13.65 vs. Ha: p > 13.65 H0: μ = 13.65 vs. Ha: μ > 13.65 H0: μ = 14.92 vs. Ha: μ > 14.92 (b) Find the test statistic: (Use 4 decimals.) (c) What is the p-value? (Use 4 decimals.) (d) What is the conclusion of the hypothesis test, for α = 0.05? --- the value $13.65. There is --- evidence the mean transaction value is greater than $13.65. (e) Regardless of your conclusion above, what is the meaning of a Type II error in this context? you conclude the average transaction value is greater than $13.65, in reality the average transaction value is greater than $13.65. You conclude the average transaction value is equal to $13.65, in reality the average transaction value is equal to $13.65. You conclude the average transaction value is greater than $13.65, in reality the average transaction value is equal to $13.65. You conclude the average transaction value is equal to $13.65, in reality the average transaction value is greater than $13.65.
Answer:
A) Null Hypothesis; H0: μ = 13.65
Alternative hypothesis; Ha: μ > 13.65
B) t = 1.42
C) The p-value is greater than the significance level of 0.05. Thus, we fail to reject the null hypothesis and conclude that there is insufficient evidence to support the claim that the mean transaction value is greater than $13.65.
D) type II error will be to conclude the average transaction value is equal to $13.65, in reality the average transaction value is greater than $13.65.
Step-by-step explanation:
We are given;
Population mean; μ = $13.65
Sample mean; x¯ = $14.92
Sample standard deviation; s = $5.51
Sample size; n = 38
DF = n - 1 = 38 - 1 = 37
Significance level; α = 0.05
A) The hypotheses is defined below;
Null Hypothesis; H0: μ = 13.65
Alternative hypothesis; Ha: μ > 13.65
B) Since we are given sample standard deviation, we will use formula for t-value. Formula for the test statistic is;
t = (x¯ - μ)/(s/√n)
t = (14.92 - 13.65)/(5.51/√38)
t = 1.42
C) From online p-value from t-score calculator attached, using; t = 1.42, α = 0.05, DF = 37, one tail, we have;
P-value = 0.08199
D) The p-value is greater than the significance level of 0.05. Thus, we fail to reject the null hypothesis and conclude that there is insufficient evidence to support the claim that the mean transaction value is greater than $13.65.
E) A type II error simply means accepting a null hypothesis that is not true.
Now, in this case what it will mean is to accept the null hypothesis.
Thus, type II error will be to conclude the average transaction value is equal to $13.65, in reality the average transaction value is greater than $13.65.

Answer:
The amount of money invested at 15% = 30,000
The amount of money invested at 5% = 30,000
Step-by-step explanation:
Calculation for How much money should be invested
Let x dollars = 15%,
Let y dollars= 5%,
x + y = 60,000
0.15x + 0.05y = 6,000
Multiply the 1st Equation by -0.15:
-0.15x - 0.15y = -9,000
0.15x + 0.05y = 6,000
Add the 2 Equations :
-0.1y = -3,000
y=3,000/0.1
y = 30,000
Substitute 30,000 for y in the 1st Equation
x + 30,000 = 60,000
x = 60,000 - 30,000
x= 30,000
PROOF:
.15*30,000+.05*30,000=6,000
4,500+1,500=6,000
6,000=6,000
Hence,
The amount of money invested at 15% = 30,000
The amount of money invested at 5% = 30,000
