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.

Answer:
n[total]=5
now
probability to Lisa and another girl are chosen to read=n[Lisa]/5×n[another girl]/4=1/5×1/5=1/25=0.04 is your answer
Step-by-step explanation:
Solution :
here ,
n= 5
then,
The probability that Lisa and another girl are chosen to read = n(Lisa)/5×n ( another girl ) /4
=1/5×1/5

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.

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]
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)

D:{(0, 4), (-5, -2), (1, 8), (-2, 5)}
9514 1404 393
Answer:
B: {(4, 0), (-2, 5), (8, -1), (5, 2)}
Step-by-step explanation:
The inverse relation has the input and output swapped:
relation: (0, 4)
inverse relation: (4, 0)
You can identify the correct answer choice using just the first ordered pair. The inverse relation is ...
{(4, 0), (-2, 5), (8, -1), (5, 2)}
Which images are tessellations?
Image 1 and 4
Image 3 and 2
Image 1 only
Image 3 and 4
Option - D - Image 3and 4 is correct
We have the following images.
We have to classify which image is a tessellations.
What are tessellations?tessellations is also called tiling which involves the covering up of rigid plane surface using the geometric shapes (tiles) ensuring that these shapes don't overlap and leave no gap.
In the image 3, we have a geometric shape called triangle which is used as a tile to cover the surface. These shapes don't overlap and leave no gap as they perfectly fit with one another. Similar is the case with image 4, where hexagonal tiles are used. Therefore, image 3 and 4 are tessellations. The images 1 and 2 does not have any predefined geometric shape and nothing can be said about their perfect fit. Hence these are not tessellations.
Hence, Option - D is correct.

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.

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
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 .

Step-by-step explanation:
The other base angle (∠B) of this isosceles triangle is also 57°. Of course, the total of all angles is 180°, so we have ...

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
