An engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such that it would produce a mean pressure of 5.4 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 24 engines and the mean pressure was 5.7 pounds/square inch with a standard deviation of 1.0. A level of significance of 0.05 will be used. Assume the population distribution is approximately normal. Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.
The p-value from the hypothesis test is 0.142 i.e., greater than the given significance level of 0.05. So, the null hypothesis is not rejected. The z-score for the given sample is 1.471.
What is the decision rule for the p-value approach to hypothesis testing?The decision rule based on p-value states,
If p > α (significance level), then the null hypothesis is not rejectedIf p < α (significance level), then the null hypothesis is rejected in favor of the alternative hypothesis.Calculation:Since it is given that the valve would produce a mean pressure of 5.4 pounds/square inch. I.e., μ = 5.4 p/si
So, Defining the hypothesis:
Null hypothesis H0: μ = 5.4
Alternative hypothesis Ha: μ ≠ 5.4
It is given that,
The valve was tested on 24 engines. I.e., Sample size n = 24
The sample mean X = 5.7
Standard deviation σ = 1.0 and
The significance level = 0.05
Since the population distribution is approximately normal,
the test statistic is calculated as follows:
z = (X - μ)/(σ/[tex]\sqrt{n}[/tex])
On substituting the value,
z = (5.7 - 5.4)/(1.0/[tex]\sqrt{24}[/tex])
= (0.3)/0.204
= 1.471
Fron this z-score, the p-value is calculated as 0.142.
Since, the value of p > 0.05 (significance level), the null hypothesis is not rejected.

Sonny substituted 5 for x in the proportion startfraction 16 over x endfraction = startfraction 48 over 15 endfraction and cross multiplied to get 240 = 240. why is this?
The cross products of the proportion are equal.
According to the question, Sonny's equation can be written as follows.
16/x = 48/15
Now, the variable x is replaced by the constant 5. So the equation can now be written as follows.
16/5 = 48/15
When two fractions are equal to one another as shown above, the constants are cross multiplied with one another in order to form an equation.
16*15= 48*5
The values of both the products are equal which is 240.

What kind of sequence is this? 206, 190, 174, 158
Answer:
Arithmetic
Step-by-step explanation:
Arithmetic Sequence is a sequence that has common difference - a common difference is same difference in a sequence. If we take next term to subtract the previous term and you keep getting same difference or value then that's a common difference. It can be mathematically expressed as an equation of:
[tex]\displaystyle{d=a_{n+1}-a_n}[/tex]
Now, I'll show why the sequence is arithmetic - take the sequence to subtract for common difference:
190 - 206 = -16174 - 190 = -16158 - 174 = -16Notice how we keep getting -16 after subtracting previous term with next term. Hence this sequence is arithmetic sequence for sure!
Geometric Sequence is a sequence with common ratio - a common ratio is similar to common difference except ratio is all about division. Since common difference is expressed as subtraction of next term and previous term then common ratio is division of next term and previous term which can be mathematically expressed as:
[tex]\displaystyle{r = \dfrac{a_{n+1}}{a_n}}[/tex]
However this sequence is not geometric sequence because if you divide next term with previous term then you'll keep getting difference result and common ratio means having same ratio or constant ratio for entire sequence.
Now see why this sequence cannot be geometric sequence:
190/206 = 0.922174/190 = 0.915158/174 = 0.908Notice that none of values are equal and thus, this sequence doesn't have common ratio which leads to not being geometric sequence.

Several different roadways are in the same region as the railroad.
Part A: A highway's path can be found using the equation 2x+3y=21. Use the graphs of the functions to determine the number of intersections there will be between the railroad and the
highway, and explain completely. (5 points)
Part B: A turnpike's route is determined by the equation y=x2 Prove algebraically how many intersections there will be between the railroad and the turnpike, showing all necessary
work. (5 points)
There are 0 intersections between the railroad and the highway and there are 2 intersections between the railroad and the turnpike
The number of intersections there will be between the railroad and the highwayFrom the graph, we have the following points on the railroad
(x, y) = (3, 3) and (0, 5)
The slope is calculated as:
m = (y2 - y1)/(x2 - x1)
This gives
m = (5 -3)/(0 - 3)
Evaluate
m = -2/3
The equation is then calculated as:
y = mx + b
This gives
y = -2/3x + b
Substitute (0, 5)
5 = -2/3 * 0 + b
This gives
b = 5
Substitute b = 5 in y = -2/3x + b
y = -2/3x + 5
Multiply through by 3
3y = -2x + 15
Rewrite as:
2x + 3y = 15
The equation of the highway's path is
2x+3y=21
So, we have:
2x+3y=21
2x + 3y = 15
Subtract the equations
2x - 2x + 3y - 3y = 21 - 15
Evaluate
0 = 6
The above equation is false because 0 and 6 are not equal.
This means that the system of equations have no solution
Hence, there are 0 intersections between the railroad and the highway.
How many intersections there will be between the railroad and the turnpike?Here, we have
y = x^2 and 2x + 3y = 15
Substitute y = x^2 in 2x + 3y = 15
2x + 3x^2 = 15
Rewrite as:
3x^2 + 2x - 15 = 0
Calculate the discriminant using
d =b^2 - 4ac
This gives
d = 2^2 - 4 * 3 * -15
Evaluate
d = 184
The discriminant d is greater than 0.
This means that the equation has 2 real solutions

Lightfoot Inc., a software development firm, has stock outstanding as follows: 30,000 shares of cumulative preferred 2% stock, $25 par, and 38,000 shares of $75 par common. During its first four years of operations, the following amounts were distributed as dividends: first year, $5,700; second year, $9,600; third year, $59,720; fourth year, $117,220.
The calculation of the dividends per share on each class of stock for each of the four years for Lightfoot Inc. are:
1st Year 2nd Year 3rd Year 4th Year
Preferred stock $0.19 $0.32 $0.99 $0.50
Common stock $0 $0 $0.79 $2.69
How is dividend per share calculated?
The dividend per share for each class of stock can be computed by dividing the total dividend distributed by the number of shares outstanding.
For cumulative preferred stock, the unpaid dividends in a year are carried forward for distribution when profits are made. Note also that preferred stock dividends enjoy preferential payment before common stock dividends.
Data and Calculations:Cumulative preferred stock = 30,000 shares
Par value of preferred stock = $25
Dividend rate = 2%
The total value of preferred stock = $750,000 ($25 x 30,000)
Expected annual dividend for preferred stockholders = $15,000 ($750,000 x 2%)
Common stock = 38,000 shares
Par value of common stock = $75
The total value of ordinary stock = $2,850,000 ($75 x 38,000)
Dividends distribution:1st Year 2nd Year 3rd Year 4th Year
Dividends distributed $5,700 $9,600 $59,720 $117,220
Preferred stock $5,700 $9,600 $29,700 $15,000
Preferred stock per share $0.19 $0.32 $0.99 $0.50 ($15,000/30,000)
Common stock $0 $0 $30,020 $102,220
Common stock per share $0 $0 $0.79 $2.69 ($102,220/38,000)
Thus, the dividends distribution of Lightfoot Inc. shows that the common stockholders started earning dividends after the second year.

[tex]\displaystyle{QR^2 = QP^2+RP^2-2QP\cdot RP \cdot \cos P}[/tex]
We know that QP = 13 cm, RP = 4 cm and cosP = 70°. Hence:

To find the number of gingerbread houses we have to put P=665.60 in the equation given which shows the profit earned by vendor.
665.60=-0.1[tex]g^{2}[/tex]+30g-1200
0.1[tex]g^{2}[/tex]-30g+1200+665.60=0
0.1[tex]g^{2}[/tex]-30g+1865.60=0
Divide the above equation by 0.1.
[tex]g^{2}[/tex]-300g+18656=0
Solving for g we get,
g=[300±[tex]\sqrt{(300)^{2}-4*1*18656 }[/tex]]/2*1
g=[300±[tex]\sqrt{90000-74624}]/2[/tex]
g=[300±[tex]\sqrt{15376}[/tex]]/2
g=(300±124)/2
g=(300+124)/2 , g=(300-124)/2
g=424/2, g=176/2
g=212,88
Because 212 is much greater than 88 so vendor prefers to choose selling of 88 gingerbread houses.
Put the value of P=1500 in equation P=-0.1[tex]g^{2}[/tex]+30g-1200.
-0.1[tex]g^{2}[/tex]+30g-1200=1500
0.1[tex]g^{2}[/tex]-30g+1500+1200=0
0.1[tex]g^{2}[/tex]-30g+2700=0
Dividing equation by 0.1.
[tex]g^{2}[/tex]-300g+27000=0
Solving the equation for finding value of g.
g=[300±[tex]\sqrt{300^{2} -4*1*27000}[/tex]]/2*1
=[300±[tex]\sqrt{90000-108000}] /2[/tex]
=[300±[tex]\sqrt{-18000}[/tex]]/2
Because [tex]\sqrt{-18000}[/tex] comes out with an imaginary number so it cannot be solved for the number of gingerbread houses.
Hence the vendor has to sell 88 gingerbread houses to earn a profit of $665.60 and there is no chance that the vendor will earn $1500.

SOMEONE HELP PLEASEiiiii
Answer: (2, -1)
Step-by-step explanation:
[tex]y=-3x^2 +12x-13\\\\y=-3(x^2 - 4x)-13\\\\y=-3\left(\left(x-2 \right)^{2}-4 \right)-13\\\\y=-3(x-2)^{2}+12-13\\\\y=-3(x-2)^2 - 1[/tex]
So, the vertex is (2, -1).
