Answer: 55/126
Step-by-step explanation:
For this equation, the easiest way to solve is to change the denominators, or bottom halves, of both fractions to be the same thing. The easiest way to do this is to multiply themselves with a “funny form” of one. A funny form of one is just a way of representing “1” with numbers that aren’t 1. “2/2” is a funny form of one. log(x)/log(x) is a funny form of one, etc..
(3/7)x(9/9)=27/63
(4/9)x(7/7)=28/63
These fractions are very close. If you are willing to settle for an unsimplified fraction, the answer here would be 27.5/63. If you aren’t willing to settle for the unsimplified form, we can multiply both fractions by a funny form of one again, most easily 2/2, and find the median of the two fractions.
(27/63)x(2/2)=54/126
(28/63)x(2/2)=56/126
The median of these two fractions is 55/126.
55/126 is exactly halfway between 3/7 and 4/9.

Answer:
Step-by-step explanation:
In the graph of y = x2, the point (0, 0) is called the vertex. The vertex is the minimum point in a parabola that opens upward. In a parabola that opens downward, the vertex is the maximum point. We can graph a parabola with a different vertex.

You are given the results of measurement of resistors. We are testing the
measurement tool. It will pass the technical control if the mean value will be
in the range [198-202] with standard deviation less than 3 Ohms. Will the tool
pass the technical control?
Answer:
As both the mean and standard deviation are in the desired ranges, the tool passes the technical control.
Step-by-step explanation:
Mean of the batch:
The mean of the batch is the sum of all values divided by the number of items. So
[tex]M = \frac{199+204+201+197+195+204+200}{7} = 200[/tex]
Mean in the desired interval.
Standard deviation:
Square root of the sum of the difference squared between each term and the mean, divided by the number of items. So
[tex]S = \sqrt{\frac{(199-200)^2+(204-200)^2+(201-200)^2+(197-200)^2+(195-200)^2+(204-200)^2+(200-200)^2}{7}} = 1.18[/tex]
As both the mean and standard deviation are in the desired ranges, the tool passes the technical control.

Answer:
8
Step-by-step explanation:
So, the small red circles are the baskets.
Each 1 represents 1 basket.
We know that the two baskets on 4 wont be counted, as well as the two baskets on 4 1/2, since thats smaller than or equal to 4 1/2
We also know that the two baskets on 6 wont be counted either, since thats equal to 6.
So now lets count the baskets in between these values, which would be:
5 - 4 baskets
5 1/2 - 4 baskets
Lets add those up:
4+4
=
8
So your answer is 8!

Find the value of x. Then tell whether the side lengths form a Pythagorean triple.
10, 6
To Find :
The value of x.
Solution :
Applying Pythagoras's theorem by assuming 10 is the biggest side, we get :
[tex]6^2 + x^2 = 10^2\\\\x = \sqrt{100 - 36}\\\\x = \sqrt{64}\\\\x = 8[/tex]
Therefore, the value of x is 8 .
you're having a bbq this weekend, and you're in charge of hamburger meat. right now there is a sale where you can buy 5 pounds of meat for $10. At this rate how much meat could you buy for $30
Answer:
15 pounds
Step-by-step explanation:
we can set up a proportion:
5/10=x/30
solve for x:
5/10=x/30
10x=150
x=15
(or you could've done 5*3=15 since $30/$10=3)

The mean area of homes in a certain city built in 2009 was 2438 square feet. Assume that a simple random sample of 11 homes in the same city built in 2010 had a mean area of 2,293 square feet, with a standard deviation of 225 square feet. An insurance company wants to know if the mean area of homes built in 2010 is less than that of homes built in 2009. Compute the P-value of the test. Write down your P-value. You will need it for the next question.
Answer:
The p-value of the test is 0.029.
Step-by-step explanation:
The mean area of homes in a certain city built in 2009 was 2438 square feet.
An insurance company wants to know if the mean area of homes built in 2010 is less than that of homes built in 2009.
This means that at the null hypothesis we test if the mean is the same as in 2009, that is:
[tex]H_0: \mu = 2438[/tex]
At the alternate hypothesis, we test that if it is less, than is;
[tex]H_a: \mu < 2438[/tex]
The test statistic is:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.
2438 is tested at the null hypothesis:
This means that [tex]\mu = 2438[/tex]
Assume that a simple random sample of 11 homes in the same city built in 2010 had a mean area of 2,293 square feet, with a standard deviation of 225 square feet.
This means that [tex]n = 11, X = 2293, s = 225[/tex]
Value of the test statistic:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{2293 - 2438}{\frac{225}{\sqrt{11}}}[/tex]
[tex]t = -2.14[/tex]
Compute the P-value of the test.
Probability of finding a mean less than a value(in this case, 2293) is a one-tailed test.
The pvalue is found for a one-tailed test, with t = -2.14 and 11 - 1 = 10 degrees of freedom. With the help of a calculator, the pvalue of the test is of 0.029
The p-value of the test is 0.029.

Answer:
2) 54 units
3) 2770 square units
Step-by-step explanation:
2) The perimeter is the sum of the lengths of the sides of the figure. The sum of the lengths of the horizontal segments is 2×16 = 32 units. All but one of the lengths of the vertical segments are given. The missing one is the inside segment on the left side, which is 9 - (6 -2) = 5 units. Then the sum of vertical segment lengths is 9 +5 +2 +6 = 22 units. The total perimeter is ...
P = 32 units + 22 units = 54 units

Step-by-step explanation:
A class consists of 23 women and 83 mean. If a student is random selected, what is the probability that the student is a woman?
Answer:
[tex]P(Woman) = \frac{23}{106}[/tex]
Step-by-step explanation:
Given
[tex]Women = 23[/tex]
[tex]Men = 83[/tex]
Required
[tex]P(Woman)[/tex]
This is calculated as the number of women divided by the population of the class
i.e.
[tex]P(Woman) = \frac{Women}{Women + Men}[/tex]
So, we have:
[tex]P(Woman) = \frac{23}{23+83}[/tex]
[tex]P(Woman) = \frac{23}{106}[/tex]
Adriyana wants to determine the difference quotient
of p(x) = x3 + x.
She writes the following first few steps.
p(x + h)
= (x + h)3 + (x + h)
= x3 + 3x2h + 3xh2 + h3 + x + h
StartFraction p (x + h) minus p (x) Over h EndFraction = StartFraction (x cubed + 3 x squared h + 3 x h squared + h cubed + x + h) minus (x cubed + x) Over h EndFraction
What is the simplified expression for the difference quotient for all nonzero values of h?
3x2 + 3xh + h2
3x2 + 3xh + h2 + 1
3x2 + 3xh + h2 + h
3x2 + 3xh + h2 + 2x + 1
Answer:
The answer is B
Step-by-step explanation:
The simplified expression for the difference quotient for all nonzero values of h is 3x² + 3xh + h² + 1 option (B) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The function is:
p(x) = x³ + x
The difference quotient of the function:
p(x + h) = (x + h)³ + (x + h)
The difference quotient of the function:
= [((x + h)³ + (x + h)) - (x³ + x)]/h
= [x³ + 3x²h + 3xh² + h³ + x + h - x³ - x]/h
= [3x²h + 2xh² + h³ + h]/h
= 3x² + 3xh + h² + 1
Thus, the simplified expression for the difference quotient for all nonzero values of h is 3x² + 3xh + h² + 1 option (B) is correct.

One number is five more than three times a second number. The sum of the numbers is 37. What are the numbers?
Answer:
11
Step-by-step explanation:
Answer:
29, 8
Step-by-step explanation:
1. let x = 1st number and y = 2nd number.
2. The 1st sentence translates into: x = 3y+5
3. 2nd sentence translates into: x + y = 37.
4. x+y = 37 --> y = 37-x
5. x = 3(37-x)+5
x = 111-3x +5
4x = 116
x = 29
y = 37-x = 37-29 = 8
6. x = 29, y = 8
