Answer:
your answer is 13.
am I correct.
The number in the riddle is 13 which applying all the operations gives 14.
let the unknown number x.
1. Add 7 to x : x + 7.
2. Subtract 10 from (x + 7):
x + 7 - 10 = x - 3
3. Subtract 5 from x - 3
(x - 3)- 5 = x -8
4. Add 10 to x -8
x -8 + 9 = x+ 1
Now, the resultant value is 14 then it an be written as
x + 1 = 14
Subtract 1 from both sides gives
x+ 1 -1 = 14 - 1
x = 13
Therefore, the number is 13.

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
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

Answer:
Step-by-step explanation:
theyre doing square root of 9 in the problem but the answer is 9 squared. you can easier change square root 9, to nine to the second power 9^2 or change the answer to 3. which is the square root of 9
Answer:
Step-by-step explanation:
Square root of 81 is 9
[tex]\sqrt{81} = 9[/tex]
or
9² = 81
or
[tex]\sqrt{9} = \sqrt{3*3}=3[/tex]

Step-by-step explanation:
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.
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.
Identify if the following statement about the graphs of the two functions is TRUE or FALSE.
"The graph of g(x) = 3(x + 4)2 – 5 is wider than the graph of f(x) = (x + 4)2 – 5."
True
False
Which equation is represented by the graph below?
y

4 3 2 1
-5 -3 2-14
1 2 3 4
-2
3
Y
O y=-2x + 2
O y=-3x+2
Answer:
y= - 1/2 +2
Step-by-step explanation:
One, the slope is negative, so you can cross some answers out right off the bat. Other than that, the answer is not a whole because it's not that steep. If you use RISE/RUN you can tell its a -1/2. Plus, the y-intercept is 2!

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

7. Find the measure of KLM and M
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°

Perpendicular, parallel, or neither?
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
Write the slope-intercept form of the equation of each line given the slope and y-intercept
