Answer:
Step-by-step explanation:
A standard die has 6 numbers, so the probability it will be greater than 4 is 6-4, or 2. Therefore the answer is , but this can be simplified to .
*Given
Total number of students - 54
Fraction of students going to lunch first - 2/3
Fraction of students going to the exhibit first - 1/3
*Solution
1. Since the students are grouped into 3, the total number of students must be divided into 3 to determine the number of students in each of the 3 groups.
54/3 = 18
Thus, there are 18 students per group.
2. Two-thirds (2/3) of the total number of students will go to lunch first. Since the total number of students have already been divided into 3 groups, this simply means that 2 of the 3 groups will go to lunch first. Since each group has 18 students, 2 groups would have,
18*2 = 36
Thus, 36 students will go to lunch first.
Answer: 1, -1
Step-by-step explanation: This is a difference of squares when factored,
(x+1)(x-1)
Let's check using FOIL(First, outside, inside, last)
x * x =x^2
1 *x =x
x * (-1) =-x
1* -1 =-1
so x^2 +x -x -1
=x^2 -1
Given that Betty saves $161 per month which is $141 less than Jack per month. find the amount that Jack will save in 2 years.
First, find how much Jack saves. We can do this buy adding 141 to 161 since Betty saves 141 less meaning we can reverse it by adding it.
141 + 161 = 302
Now, that we know how much Jack saves per month.
Then, we have to find out how many months are in 2 years.
We already know that there is 12 months in a year, so for 2 years, we can simply multiply by 2.
12 x 2 = 24
Therefore, there are 24 months in two years.
Lastly, multiply 24 months by the amount that Jack saves to get the amount in total.
24 x 302 = 7,248
Thus, Jack will save approximately $7,248 in 2 years.
