Answer:
The measures of the angles are 16° and 164°.
Step-by-step explanation:
Let the smaller angle be x and the larger angle be 8x+36.
Supplementary angles add up to 180°.
Small angle + Large angle = 180°
x + 8x + 36 = 180
9x + 36 = 180
9x = 180 - 36
= 144
x = 144 ÷ 9
x = 16
8x+36 = 8(16)+36
= 164
In statistical inference for categorical data:___________.
a. Normal data is always a condition for inference.
b. Normal data is never one of the inference assumptions.
c. Normal data or large enough total sample size is one of the inference assumptions.
Answer:
b. Normal data is never one of the inference assumptions.
Step-by-step explanation:
A categorical data specifies among two or more groups, which one each observation belongs to, and one or more explanatory variables that can be used to predict this membership.
So, there are two propositions in statistical inference for categorical data
1. That each data in a cell is independent of the others.
2. That samples are randomly drawn.
Thus, there is no room for normality.
Suppose you have 9 tubes of paint. How many distinct color groupings can you make with your paint?
9514 1404 393
Answer:
511
Step-by-step explanation:
Each tube can be included in the mix, or not. There are 2^9 = 512 possible subsets of a set of 9 objects, including the complete set and the empty set. The empty set will not make a color, so there are ...
2^9 - 1 = 511 distinct color groupings that can be made
__
The assumption in the above answer is that no tube color can be made by any combination of other tube colors.* We also assume that the choice of tubes is what makes a "color grouping", and that the colors within that grouping made by using different ratios of paint quantities are not counted separately.

The Martin family and the Kelly family each used their sprinklers last summer. The water output rate for the Martin family's sprinkler was 30L per hour. The water output rate for the Kelly family's sprinkler was 35L per hour. The families used their sprinklers for a combined total of 60 hours resulting in a total water output of 1925L. How long was each sprinkler used?
Answer:
The Martins used their sprinkler for 35 hours, while the Kellys used their sprinkler for 25 hours.
Step-by-step explanation:
As the Martins and the Kellys used their sprinklers for 60 hours combined last summer, and the water output rate of the Martins' sprinkler is 30 liters per hour, while the Kelly's is 35 liters per hour To determine how many hours each family used their sprinklers, knowing that in total 1925 liters of water were used, the following logical reasoning must be carried out:
There is a 5 liter difference between the Kelly sprinkler and the Martin sprinkler. If both used 30 liters of water per hour, for 60 hours 1800 liters (30 x 60) would have been used. Therefore, there is an excess of 125 liters that corresponds to an excess of consumption, attributable to the Kelly sprinkler, which consumes 5 liters more of water per hour than the Martin's. Thus, since 125/5 equals 25, in total the Kellys used their sprinkler for 25 hours, while the Martins did it for 35 hours.
This reasoning is proved with the following calculation:
25 x 35 = 875
35 x 30 = 1,050
875 + 1,050 = 1,925

Step-by-step explanation:
Let's solve your equation step-by-step.
(3)(1)+2x=6
Step 1: Simplify both sides of the equation.
(3)(1)+2x=6
3+2x=6
2x+3=6
Step 2: Subtract 3 from both sides.
2x+3−3=6−3
2x=3
Step 3: Divide both sides by 2.
2x/2 3/2
x = 3/2

Cecil weighs the same as the combined weight of Bruce and Alan. Use the expressions you found in parts A and B to write an expression
for Cecil's weight in terms of Dylan's weight.
Answer: Cecil’s weight is the sum of Alan's weight and Bruce's weight.
Alan’s weight in terms of Dylan's weight is 2d + 3.
Bruce’s weight in terms of Dylan's weight in 3d − 12.
So, the expression for Cecil’s weight in terms of Dylan’s weight is (2d + 3) + (3d − 12).

A holiday tree is 4 feet 8 inches tall. There are 2.54 centimeters in one inch. What is the tree’s height in centimeters?
Answer:
The tree's height is 142.24 cm.
Step-by-step explanation:
There are 12 inches in a foot. This means that 4 feet equal 4 * 12 = 48 inches. Since there are 8 more inches, you add 8 to 48. The sum is 56. There are 56 inches in 4 feet and 8 inches.
Now, to convert:
56 * 2.54 = 142.24 (inches to centimeters)
The tree's height is 142.24 cm.
