The solution to this problem is as follows:
1. Assign your variables.
Let X = first integer
X+2 = second integer
X+4 = third integer
*note: multiples of 2 are added because the problem states that they are consecutive even integers.
2. Formulate the equation
4X = 6 + 2(X+4)
X=7
3. Solve other variables
first integer = 7
second integer = 7+2 = 9
third integer = 7+4 = 11
As you can see, the answers are all odd which means that the given information in the problem should say odd, not even.
Hello!
So if each box has 14 favors, what we need to do is add until we have enough, or more than enough for each of the children that will be at the party to get two of them.
So to start, 14+14=28. There are 28 children going, but each child must have two favors, not one. So, we simply add on two more boxes. 28+14=42, 42+14=56. So, we need 56 favors for each child to get two.
You could multiply to make this problem faster, but adding works out easier in my head. Sorry to drag it out!
So to make it simple, you need four boxes of favors for each child to get two.
Hope this helps, have an awesome day!
Answer:
The correct answer is 2.2.
Step-by-step explanation:
The following represents the probability distribution for the daily demand of microcomputers at a local store:
Demand Probability
f(0)= .1
f(1)= .2
f(2)= .3
f(3)= .2
f(4)= .2.
Expectation of a discrete probability function f of the random variable x is given by ∑ x × f(x).
Thus the expected value of demand is given by
0.1 × 0 + 0.2 × 1 + 0.3 × 2 + 0.2 × 3 + 0.2 × 4 = 2.2.
The expected daily demand is 2.2.
1. You would do 45 × 3 = 135 miles
2. 630 ÷ 2 = 315. 630 + 315 = 945 miles
3. 54 × 11 = 594 miles
1. Time is distance ÷ speed, so 4760 ÷ 560 = 8 1/2hours
2. 27 ÷ 54 = 0.5 hours, or 30 minutes
3. 1748 ÷ 437 = 4 hours
I hope this helps!
Answer:
x=14
Step-by-step explanation:
x-4=⅓(6x-54)
x-4=2x-18
x+14=2x
x=14
