Answer:
1/3
Step-by-step explanation:
since number 2 card was not replaced, we have;
probability of picking a second card, 3;
let S be number of sample space
n(S)= 4
n(3)= 1
Pr(3/2)= 1/3
(because since one was already chosen and n, the sample space would reduce)
17.32 deal with it aaaaaaaaaaaaaaaaa
Answer:
67°F
Step-by-step explanation:
The mean is another way to say average.
To find the average: you have to add up all of the temperatures, then divide by how many numbers (in this case, time slots) are there.
58°F + 60°F + 61°F + 67°F + 69°F + 73°F + 74°F + 74°F = 536°F
536°F ÷ 8 (total number of time slots) = 67°F
I think that the answer is A.
For this case we have to:
x: Represents the unknown number
y: Represents the exponent of base 10
So, considering a system of equations we have:

From the first equation we have:

Substituting in the second equation:

We choose the positive value:

So, the number is 0.4.
So:

Thus, the exponent is 5.
Answer:
Yara use 0.4 and
