I'm not sure but here you go

$2.75 + $3.15 = $5.90

C. $5.90

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)

Good luck !

Answer:

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:

C. 35

Step-by-step explanation:

I just went through all the numbers, multiplied them by 2, because you start with x which is 50, and the goal is to get to 120 with 50 and a number multiplied by two, so I tried 35 which would be 70 when multiplied by two, then added 50, which would make 120.

  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

The fraction that is equal to 6 can be some of the following:

[tex]\mathbf{\dfrac{6}{1} \ ; \dfrac{12}{2} \ ; \dfrac{18}{3} \ ; \ \dfrac{24}{4}\ ; \ \dfrac{36}{6} }[/tex]

A fraction usually comprises a numerator and a denominator separated by a division line.

The factors of a given number are the numbers that can be divided in such a given number without a remainder.

From the given example, we are to determine the factors of 6, so we will think about a number that can be divided by 6 without leaving any remainder.

These numbers are:

From these numbers, we can pick two factors that when divided together, we get 6 as our result and without any remainder.

i.e.

The fraction that is equal to 6 are:

[tex]\mathbf{\dfrac{6}{1} \ ; \dfrac{12}{2} \ ; \dfrac{18}{3} \ ; \ \dfrac{24}{4}\ ; \ \dfrac{36}{6} }[/tex]
