Answer:
9
Step-by-step explanation:
3 times the sum of 4 and 2 = 3*(4+2)
= 3 * 6
= 18
18 - 9 = 9
To do this problem, add up all the numbers and divide by the amount of numbers:
1.01+1.03+.98+.99+1.01+1.02+.98+1.05+.97+.98
10.02
Now divide by 10 (the amount of samples)
10.02/10
1.002
The Mean of the Data Set is 1.002
Hope this helps!

The amount of red cars dropped the greatest during this time, therefor it increased at the slowest rate
The Line PQ is cut half equally by point T. MEANING PT=TQ!!! So first, write out the equation.
PT = TQ
20?5x+3=7x-9
21?4x-6=3x+4
22?7x-24=6x-2
The question asks you to find the value of PT, but you’ll have to find the value of x first.
x=6
x=10
x=22
And then just just plug in x in just the PT equation.
5(6)+3= 33
4(10)-6= 34
7(22)-24= 130
and there you have it
20?=33
21?=34
22?=130
Answer:
98450 > 2560 * (1.5)^(t/2)
Step-by-step explanation:
We are told that there are 2560 cells in the test tube. Then they tell us that every 2 minutes, the number of cells increases by 50%. At 98,450 cells, the test tube will explode. Since Louie got to the lab before the tube exploded, 98,450 is greater than. On the other side of the inequality, we get 2560 times 1.5, because it is increasing by 50%. Then we put 1.5 to the power of t/2 because it grows by 50% every two minutes. The end result is 98450 > 2560 * (1.5)^(t/2). Hope this helps.
