Answer:

0.27

Step-by-step explanation:

The standard deviation of a uniform distribution is:

σ² = (b − a)² / 12

σ² = (32.51 − 31.58)² / 12

σ² = 0.0721

σ = 0.268

Rounded to the hundredths place, the standard deviation is 0.27.

To solve this question, we use concepts of the uniform probability distribution.

Using this, we get that the standard deviation in volumes of quart-size Hellmann's mayonnaise jars is of 0.2685 fluid ounces.

Uniform probability distribution:

An uniform distribution has two bounds, a and b.

The standard deviation is:

[tex]S = \sqrt{\frac{(b-a)^2}{12}}[/tex]

The actual volumes of quart-size jars of Hellmann's mayonnaise are uniformly distributed from 31.58 to 32.51 fluid ounces.

This means that [tex]a = 31.58, b = 32.51[/tex]

Find the standard deviation in volumes of quart-size Hellmann's mayonnaise jars (in fluid ounces).

[tex]S = \sqrt{\frac{(32.51 - 31.58)^2}{12}} = 0.2685[/tex]

Thus, the standard deviation is of 0.2685 fluid ounces.

Answer:

Sample Response: The vertical line test is a way to determine if a relation is a function. This test determines if one input has exactly one output on the graph. If any vertical line passes through more than one point on the graph, then the relation is not a function because two different outputs have the same input.

Step-by-step explanation:

I just got the sample response.

The vertical line test is a method used to determine whether a graph represents a function or not.

The vertical line test is a method used to determine whether a graph represents a function or not. It is a visual tool that helps identify if there is a unique output for every input value in a given graph.

To perform the vertical line test, imagine a vertical line that can be moved across the graph. If the vertical line intersects the graph at only one point for every possible position, then the graph represents a function.

In other words, if no vertical line passes through the graph in more than one location, the graph passes the vertical line test and is considered a function.

The vertical line test is a simple and effective way to check if a graph represents a function visually. It helps determine the relationship between the input and output values and identifies whether there is a one-to-one correspondence or not.

a = 66 points (first test)

b = 98 (second test)

Hi there !

a = first test

b = second test

a + b = 164

b = a + 32

replace b

a + (a + 32) = 164

2a = 164 - 32

2a = 132

a = 132 ; 2

a = 66 points (first test)

b = 66 + 32

b = 98 (second test)

Answer:

  linear equation in the point-slope form

Step-by-step explanation:

There are many forms an equation for a line may take. Some of the ones commonly seen are ...

  ax +by = c . . . . standard form (a,b,c mutually prime integers; a>0)

  y = mx + b . . . . slope-intercept form (m=slope; b=y-intercept)

  y -k = m(x -h) . . . . point-slope form (m=slope, (h, k)=point)

__

and some additional ones I commonly use are ...

  x/(x-intercept) +y/(y-intercept) = 1

  y = m(x -h) +k . . . . variation of point-slope form (m=slope; (h, k)=point)

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1 . . . . two-point form (points (x1, y1) and (x2, y2))

  bx -ay = bh-ak . . . . line perpendicular to standard form line ax +by = c through point (h, k)

__

If you compare these forms to the equation you're given, you see it matches the "point-slope form" for point (4, 2) and slope 7.

Answer:

It should be 100 days sample so that the margin of error will be 39.2 tons or less

Step-by-step explanation:

We are given that A coal company wants to determine a 95% confidence interval estimate for the average daily tonnage of coal that it mines.

[tex]\alpha = 0.05[/tex]

To Find two tailed critical value using Z table

[tex]Z_{\frac{\alpha}{2}}=Z_{\frac{0.05}{2}}=\pm 1.96[/tex]

Margin of error = ME = 39.2

[tex]\sigma = 200[/tex]

Formula : [tex]n = (\frac{Z_{\frac{\alpha}{2}} \times \sigma}{ME})^2[/tex]

[tex]n = (\frac{1.96 \times 200}{39.2})^2[/tex]

n=100

Hence it should be 100 days sample so that the margin of error will be 39.2 tons or less

Answer:

y = 7

Step-by-step explanation:

First, find the value of x.

[tex] (12x + 9) + (8x + 11) = 180 [/tex] (linear pair)

Solve for x

[tex] 12x + 9 + 8x + 11 = 180 [/tex]

Collect like terms

[tex] 12x + 8x + 9 + 11 = 180 [/tex]

[tex] 20x + 20 = 180 [/tex]

Subtract 20 from both sides

[tex] 20x + 20 - 20 = 180 - 20 [/tex]

[tex] 20x = 160 [/tex]

Divide both sides by 20

[tex] \frac{20x}{20} = \frac{160}{20} [/tex]

[tex] x = 8 [/tex]

Thus,

[tex] (12x + 9) = (14y + 7) [/tex] (vertical angles)

Plug in the value of x, and solve for y

[tex] 12(8) + 9 = 14y + 7 [/tex]

[tex] 96 + 9 = 14y + 7 [/tex]

[tex] 105 = 14y + 7 [/tex]

Subtract 7 from each side

[tex] 105 - 7 = 14y + 7 - 7 [/tex]

[tex] 98 = 14y [/tex]

Divide both sides by 14

[tex] \frac{98}{14} = \frac{14y}{14} [/tex]

[tex] 7 = y [/tex]

Answer:

hope it helps you

Step-by-step explanation:

Let

A be the set of students in art class

B be the set of students in dance class

n(A) = 35    

n(B) = 57      

a) When 2 classes meet at different hours and n(A ∩ B) = 12 we have:

n(A ∪ B) = n(A) + n(B) - n(A ∩ B) = 35 + 57 - 12 = 80

b) When two classes meet at the same hour we have A∩B = ∅ that is n(A ∩ B) = 0 and

n(A ∪ B) = n(A) + n(B) - n(A ∩ B) = n(A) + n(B)  = 35 + 57 = 92

Answer:

228-12 = 6w +12 -12

216 = 6w

divide both sides by 6

216/6 =6w/6

36 = w

so width = 36 feet

then the length is ..

l = 2w + 6

= 2*36 +6

= 72 +6=78

so the length = 78 feet
