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:

accept Null hypothesis at ∝ = 0.05

Step-by-step explanation:

To test the hypothesis that:  X is b( 3, 0.3 )  ( Null hypothesis )

Let X = number of heads out of three spins

In three spins there were 4 outcomes

Ao = 0 , A1 = 1 , A2 = 2 , A2 = 3   { 0,1,2,3 } outcomes in three spins

next: lets determine the probability of each result

attached below  is the detailed solution

Answer:

A

Step-by-step explanation:

It was the correct answer when I submitted my assignment. A histogram is best for continuous data thats why a bar graph is best.

Answer:

1) Compares data that are in categories

2) Organises data into 4 groups of equal sizes and is often used to compare two sets of data.

3) Used to see trends in data.

4) Shows changes over time.

5) Shows the frequency of data using equal intervals with no space between the bars.

Step-by-step explanation:

1) Bar graph is used to compare data that are in categories

2) Box and whisker plot is used to organise data into 4 groups of equal size.

3) Line graph is basically used to see different trends.

4) Scatter plot is used to show changes that have occurred over time

5) Histogram is used to show the frequency of data using equal intervals with no space between the bars.

Answer:

[tex]\boxed {\boxed {\sf x=28}}[/tex]

Step-by-step explanation:

This is a right triangle. The small square in the corner represents a 90 degree angle. We can use trigonometry. The three major ratios are:

The angle, or θ, is 60 degrees. The side measuring 14 is adjacent to this angle. x is the hypotenuse because it is opposite the right angle. Since we have the adjacent side and the hypotenuse, we use cosine.

[tex]cos (\theta) = \frac {adjacent}{hypotenuse}[/tex]

[tex]cos(60)= \frac{14}{x}[/tex]

Since we are solving x, we must isolate the variable. First, cross multiply.

[tex]\frac {cos(60)}{1}= \frac{14}{x}[/tex]

Multiply the first numerator (cos60) by the second denominator (x).

Then, multiply the first denominator (1) by the second numerator (14)

[tex]cos (60)*x= 14*1[/tex]

[tex]cos(60)*x= 14[/tex]

The cosine of 60 is equal to 1/2,

[tex]\frac{1}{2} x= 14[/tex]

x is being multiplied by 1/2. The inverse of multiplication is division. Divide both sides of the equation by 1/2. Since this is a fraction, you can also multiply by the reciprocal: 2.

[tex]2* \frac{1}{2} x= 14 *2[/tex]

[tex]x=14 *2\\ x=28[/tex]

The hypotenuse, x, is equal to 28.

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)}

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.

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

Answer: 1/2

First you do 4/4 times 4/4. Which is equal to 1. Then, you multiply by 2/4 to get 1/2.

Answer:

43% probability of being moderate

Step-by-step explanation:

Since the formating is a little messed up, I assumed that the first column was liberal, second was moderate, and the third was conservative.

Answer:

n = 0.0224

Step-by-step explanation:

The given expression is :

92n = 404n-7

We need to solve it for n.

Subtract 92n from both sides,

92n-92n = 404n-7-92n

7 = 404n-92n

7 = 312 n

n = 0.0224

So, the value of n is equal to 0.0224.

Answer:

4) n = 12

5) n = 2.5

Step-by-step explanation:

4) 45/4 = 11.25

135/11.25 = 12

5) 2/1 = 2

5/2 = 2.5

Answer: 74.10

The largest possible tens place will be: 70 (7)

The largest possible ones place will be :4 (4)

The largest possible tenths place will be: 0.1 (1)

The largest possible hundredths place will be: 0.00 (0)

Answer:

The mean is 38, the median is 34, the mode is 34

Step-by-step explanation:

mean: add all the numbers then divide by how many numbers there are in the data set, there were 7 test scores so in this case, divide  by 7

median: the number in the middle when you order the numbers from least to greatest

mode: most commonly used number; number that appears most often.

hope this helps!

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 .

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:

x = 5.5

Step-by-step explanation:

tan 20° = [tex]\frac{x}{15}[/tex]

[tex]\frac{36397}{100000} =\frac{x}{15}[/tex]

100000x = 5459

x = 5.459

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)

Answer:

r = 0, r = 8

Step-by-step explanation:

Given

r² - 8r = 0 ← factor out r from each term

r(r - 8) = 0

Equate each factor to zero and solve for r

r = 0

r - 8 = 0 ⇒ r = 8

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!

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]
