Complete Question

Find the standard deviation of this probability distribution. Give your answer to at least 2 decimal places

           x        1        2         3           4          5

         P(x)      0     0.31     0.12     0.23       0.4

Answer:

The value is  [tex]\sigma = 0.89[/tex]

Step-by-step explanation:

From the question we are told that

  The probability distribution is  

           x        1        2         3           4          5

         P(x)      0     0.31     0.12     0.23       0.4

So

           [tex]x^2[/tex]     1           4         9          16           25  

Generally the mean is mathematically represented as

            [tex]E(X) = \sum [x * P(x)][/tex]

=>         [tex]E(X) = (1 * 0) + (2 * 0.31 ) + (3 * 0.12 ) + (4 * 0.23) + (5 * 0.4 )[/tex]

=>         [tex]E(X) = 3.9[/tex]

Generally  

      [tex]E(X^2) = \sum [X^2 * P(x)][/tex]

=>   [tex]E(X^2) = (1 * 0) + (4 * 0.31 ) + (9 * 0.12) + (16 * 0.23) + (25 * 0.4)[/tex]

=>   [tex]E(X^2) =16[/tex]

Generally the variance of this probability distribution is

      [tex]V(X) = E(X^2) - [E(X)]^2[/tex]

     [tex]V(X) = 16 - 3.9^2[/tex]

    [tex]V(X) = 0.79[/tex]

Generally the standard deviation of this probability distribution is  

       [tex]\sigma = \sqrt{V(x)}[/tex]

=>    [tex]\sigma = \sqrt{0.79}[/tex]

=>    [tex]\sigma = 0.889[/tex]

The p-value for the test statistic: [tex]Z_o=-1.96[/tex] is 0.025.

In statistics, the p-value is a measure that quantifies the strength of evidence against a null hypothesis. It represents the probability of observing a result as extreme as, or more extreme than, the one obtained in a statistical test, assuming that the null hypothesis is true.

The null hypothesis, denoted as H₀, represents the default or initial assumption that there is no significant difference or relationship between variables or no effect of a treatment. The alternative hypothesis, denoted as H₁, suggests the existence of a significant difference or relationship.

The p-value for the test statistic: [tex]Z_o=-1.96[/tex]:

p-value = P{[tex]Z_o < -1.96[/tex]}

             = 0.025.

So, the required p-value is 0.025.

For The Hypothesis Test H0:-7 Against H 1: 7 And Variance Known, Calculate The P Value For The Following Test Statistic: [tex]Z_o < -1.96[/tex]. Round your answer to three decimal places (e.g. 98.765).

Answer:

98/2

Step-by-step explanation:

The numbers in 14 divided by 2/7 are labeled below:

14 = whole number

2 = numerator

7 = denominator

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

14 x 7

2

 =    

98

2

Thus, the answer to 14 divided by 2/7 in fraction form is:

98

2

To make the answer to 14 divided by 2/7 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

98 / 2 = 49

The answer is rounded to the nearest two decimal points if necessary.

98/2 can be simplified to 49/1.

49/1 is an improper fraction and should be written as 49.

the simplest form of 14 divided by 2/7 is 49.

To divide 14 by 2/7, we can convert the division operation into multiplication by taking the reciprocal (flipping) of the divisor. The reciprocal of 2/7 is 7/2. So, we have 14 multiplied by 7/2.

To simplify this further, we can cancel common factors between the numerator of 14 and the denominator of 2. Both 14 and 2 share a common factor of 2. Dividing both by 2, we get 7 and 1 respectively.

Therefore, the division 14 divided by 2/7 simplifies to 7 multiplied by 7/1, which equals 49. Thus, the simplest form of 14 divided by 2/7 is 49.

Answer:

7 large boxes and 2 small boxes

Step-by-step explanation:

if you take 350 and times it by 7 you get 2450 then add 2 small boxes which are 50 each and you have 2550 and 5 more large boxes then small

The contractor purchased 2 no. of small boxes and 7 large boxes.

A linear equation is an algebraic equation of highest degree 1.

According to the given question A contractor needs to buy nails to build a house.

The nails come in small boxes and large boxes. Each small box has 50 nails and each large box has 350 nails.

The contractor bought 5 more large boxes than small boxes,So assuming he bought x no. of small boxes.

∴ He bought (x+5) nos. of large boxes.

So, 50(x) + 350(x+5) = 2550.

50x + 350x + 1750 = 2550.

400x = 2550 - 1750.

400x = 800.

x = 2.

∴ Large no. of boxes he purchased is 7.

Step-by-step explanation:

simplify it

Step-by-step explanation:

Given the values  9.657 and 6.475. Before we can know how much smaller is the 7 in the second number compare to the first, we need to get their place values first.

For 9.657

The place value of 7 in this value is 7 thousandth

7 thousandth = 7/1000 = 0.007

For 6.475

The place value of 7 in this value is 7 hundredth

7 hundredth= 70/1000 =7/100 = 0.07

Hence the value of 7 in the first is smaller that that of the second.TO know by how much, we will take the ratio of the two values

Find their ratios:

0.07/0.007 = 7/100 ÷ 7/1000

= 7/100×1000/7

= 7000/700

= 10

This means that the place value of 7 in 9.657 is 10 times smaller than the value of 7 in 6.475

Answer:

  40 units²

Step-by-step explanation:

You can figure the side lengths using the distance formula, or you can use a formula for finding area from coordinates. The latter looks like ...

  [tex]\displaystyle A=\dfrac{1}{2}\left|\sum\limits_{k=1}^n{x_k(y_{k-1}-y_{k+1})}\right|\qquad\text{where $y_0=y_n$ and $y_{n+1}=y_1$}[/tex]

So, the area is ...

  A = (1/2)|(-6(-5-1) +2(-1-7) +2(1-3) +3(7+3) +3(3+5) -5(-3+1)|

  = (1/2)|36 -16 -4 +30 +24 +10| = (1/2)(80)

 A = 40

The area of the figure is 40 units².

Answer: y=-5x+2

Step-by-step explanation: Luckily for you, they already pretty much gave you all the information you need for this problem. Keep in mind that the standard form for linear equations is y=mx+b, where m is slope and b is figure 0, or the y-intercept. So, all you have to do is substitute the values for the given information. You know that -5 is the slope, m, and (0,2) is the y-intercept, or b (you know that this is the y-intercept because x is at zero). So, you'd be left with y=-5x+2.

Answer:

2. m∠1 = 129°

3. m∠1 = 37°

Step-by-step explanation:

We know that the sum of all interior angles in a triangle adds up to 180°.

2. To find measure 1 for problem 2, we can see that ∠1 is a supplementary angle with the interior angle in side

180°-(67°+62°)

180°-129°

51°

Now that we found the missing interior angle, we can find ∠1

180°-51° = 129°

m∠1 = 129°

3. Same thing as well for this problem except we're going to be going reverse we need to find the supplementary angle first, then we can find m∠1.

180°-152° = 28°

Now that we found the interior angle, we can find m∠1

180° - (115°+28°)

180°-(143°)

37°

m∠1 = 37°
