What is the critical value for the F- test at 95% confidence? DF SS MS F p Factor 3 13.500 4.500 5.17 0.011 Error 16 13.925 0.870 Total 19 27.425

Answers

Answer:

3.239

Step-by-step explanation:

Given the ANOVA table :

_______DF _____SS____ MS___ F___ p

Factor __3 ___13.500__ 4.500 _5.17 __0.011

Error ___16 __ 13.925 ___0.870

Total ___19 __ 27.425

The critical value for the F - test at 95%

Using the F- test critical value calculator :

Where α = 1 - 95% = 1 - 0.95 = 0.05

Numerator degree of freedom = (DF of factor) = 3

Denominator degree of freedom = (DF of Error) = 16

Significance level = 0.05

Inputting the values into the calculator gives a F critical value of 3.239

7. Find the measure of KLM and M
​

Answers

Answer:

m∠KLM = 64° ; m∠M = 26°

Step-by-step explanation:

(20x + 4)° = (6x + 4)° + (8x + 18)°

20x + 4 = 14x + 22

6x = 18

x = 3

m∠KLM = (20×3 + 4)° = 64°

m∠M = 90° - 64° = 26°

You make a carbonated beverage by adding 7 ounces of soda water for every 3 ounces of regular water. Your friend uses 11 ounces of soda water for every 4 ounces of regular water. Whose beverage is more carbonated? Create a ratio table for each. Then compare.

Answers

Answer:

Second beverage

Step-by-step explanation:

The proportion of soda in the drink will show us how carbonated a beverage is. The proportion of soda is the ounce of soda divided by the sum of the soda and water.

Proportion of soda in the first beverage

[tex]\dfrac{7}{7+3}=\dfrac{7}{10}=0.7[/tex]

Proportion of soda in the second beverage

[tex]\dfrac{11}{11+4}=\dfrac{11}{15}=0.73[/tex]

So, the second beverage is more carbonated.

Sam has 43 pencils. Abby has twice as many pencils as Sam. How many pencils do they have altogether?

Answers

Answer:

86 altogether.

Step-by-step explanation:

Since she has twice as many, you would do 43 x 2 = 86

Answer:

129

Step-by-step explanation:

Sam = 43 (s)

Abby = 2s

s + 2s = 3s

3s, when s = 43, equals 129

Perpendicular, parallel, or neither?

Answers

Answer:

The two lines are parallel

Step-by-step explanation:

Parallel lines have equal slopes and different y-interceptsThe product of the slopes of the perpendicular lines is -1 which means if the slope of one is m, then the slope of the other is [tex]-\frac{1}{m}[/tex] (reciprocal m and change its sign)The slope of the equation ax + by = c is m = [tex]\frac{-a}{b}[/tex]The slope of the equation by = ax + c is m = [tex]\frac{a}{b}[/tex]

Let us use these rules to solve the question

∵ The 1st equation is -4y = -2x + b

∴ a = -2 and b = -4

∵ m = [tex]\frac{a}{b}[/tex] in this form of the equation

∴ m = [tex]\frac{-2}{-4}[/tex]

∴ m1 = [tex]\frac{1}{2}[/tex]

∵ The 2nd equation is 3x - 6y = 6

∴ a = 3 and b = -6

∵ m = [tex]\frac{-a}{b}[/tex] in this form of the equation

∴ m = [tex]\frac{-3}{-6}[/tex]

∴ m2 = [tex]\frac{1}{2}[/tex]

∵ m1 = m2

∴ The slopes of the two lines are equal

→ That means the two lines are parallel

∴ The two lines are parallel
