Answer:
This test batch can be chosen in 2380 ways
Step-by-step explanation:
The order in which the batteries are chosen is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
In how many ways can this test batch be chosen?
4 batteries from a set of 17. So
This test batch can be chosen in 2380 ways
Answer:
See below
Step-by-step explanation:
<u>Taking the readings from the graph</u>
- <u>x .... y</u>
- 0 .... 2
- 2 .... 6
- 4 .... 10
- 6 .... 14
<u>Rate of change for the given line is:</u>
- (6 - 2)/2 = 4/2 = 2
- y- intercept is 2
<u>Equation for the line is:</u>
<u>For the point (40, 76) we can verify with the equation:</u>
The point (40, 76) is close the line but the line doesn't pass through it.
Answer:
There will be 916 ants alive after 4 months.
Step-by-step explanation:
Step 1
Let's change the percentage to a decimal by dividing by a 100.
6.5% / 100 = .065
Step 2
So, for the first month we will multiply the initial amount of ants by .065 and this will give us the number of ants that die.
1200 * .065 = 78
This means that after the first month, 1200 - 78 = 1122 ants will be alive.
Step 3
Now for the second month: 1122 * .065 = 72.93 (rounded to 73)
1122 - 73 = 1049 ants will be alive
Step 4
For the third month 1049 * .065 = 68.185 (rounded to 68)
1049 - 68 = 981 ants will be alive
Step 5
For the fourth month 981 * .065 = 63.765 (rounded to 64)
981 - 64 = 916 ants will be alive
Hope this helps!
Meal cost $ 21.62
plus 9% tax = $21.62 * 1.09 = $ 23.57
meal & tax = $ 23.57 plus17% tip = $ 23.57 * 1.17 = $ 27.58
Total cost $ 27.58
