Answer:
81
Step-by-step explanation:
12/3 = 4
4 - 2 = 2
x = 2
using the order of operations, you would first have to do y + 3
y = 12
12 + 3 = 15
the equation simplified is 3 x 2 + 5 x 15
3 x 2 = 6
5 x 15 = 75
75 + 6 = 81
Answer:
0.918 is the probability that the sample average sediment density is at most 3.00
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 2.80
Standard Deviation, σ = 0.85
Sample size,n = 35
We are given that the distribution of sediment density is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling:
P(sample average sediment density is at most 3.00)
Calculation the value from standard normal z table, we have,
0.918 is the probability that the sample average sediment density is at most 3.00
First find numbers that the denominator and the numerator can both be divided with. Such as 3, now 6/3=2 and 9/3=3. So basically it is 2/3. 6/9 simplify to 2/3.
<span>The statement 3+3=6 serves as a disproof to the conjecture that the sum of two odd numbers is an odd number.
Odd numbers are numbers which can </span><span> NOT be divided evenly into groups of </span>two<span>.
6 can be divided by 2 (6:3=2), which means that the sum of two odd numbers is not an odd number.
</span>On the other hand, there is a statement that is always true (a theorem) about the sum of two odd numbers: <span>The sum of two consecutive odd numbers is </span>divisible<span> by 4. </span>
If you do 1 literally divided by 5, because that's basically what it's asking for, you get .2, so it's A
