Answer:
|-2| + |4|
= 6
Step-by-step explanation:
The absolute value is the distance from zero on the number line, so you would use the expression above to get the answer, 6

Answer: They will take 3 3/4 hours to paint the room together.
------------------------------------------------
A more detailed explanation:
------------------------------------------------
Alice:
6 hours = 1 room
1 hour = 1/6 of the room
Tom:
10 hours = 1 room
1 hour = 1/10 of the room
Alice and Tom together:
1 hour = 1/6 + 1/10 = 4/15 of the room
4/15 of the room = 1 hour
1/15 of the room = 1 ÷ 4 = 1/4 hour
15/15 of the room = 1/4 x 15 = 15/4 = 3 3/4 hours
Answer: They will take 3 3/4 hours to paint the room together.
Short Answer D
P(1) = 1(1+1)(2*1 + 1)/6
P(1) = 1(2)(2 +1) / 6
P(1) = 1(2)(3)/6
P(1) = 1
P(2) = 2(2+1)(2*2 + 1) / 6
P(2) = 2(3)(5) / 6
P(2) = 5 So this formula is adding as it goes along. To Find the Total all we need do is use the formula to calculate P(1) to P(7)
P(7) = 7*(7 + 1)(2*7 + 1)/6
P(7) = 7 * 8 * 15 / 6
P(7) = 7 * 4 * 5
P(7) = 140 <<<< Answer
Step-by-step explanation:
Use the following information to answer the next 14 exercises: The mean age for all Foothill College students for a recent Fall term was 33.2. The population standard deviation has been pretty consistent at 15. Suppose that twenty-five Winter students were randomly selected. The mean age for the sample was 30.4. We are interested in the true mean age for Winter Foothill College students. Let X = the age of a Winter Foothill College student. n=
The seventh term is 23.
Step-by-step explanation:
- Step 1: This is an Arithmetic Progression 11, 13, 15...
Given, First term, a = 11
- Step 2: Find Common difference, d =
13 - 11 = 2
- Step 3: Formula for nth term in an AP, a(n) = a + (n-1) d
- Step 4: Substitute for 7th term, a(7) = 11 + (7 - 1) 2
= 11 + (6*2)
= 11 + 12 = 23
