X + 4/5 = 11
x = 11 - 4/5
x = 55/5 - 4/5
x = 51/5 or 10 1/5
or u can do it this way..
x + 4/5 = 11.....multiply everything by common denominator of 5
5x + 4 = 55
5x = 55 - 4
5x = 51
x = 51/5 or 10 1/5
Answer: C) (9000x5) + (300x5) + (8~5) + (1x5)
Step-by-step explanation:
First Find what 9381 times 5 is.
9381x5=46108
Now Find out all the equations.
9000x5= 45000
300x5=1500
8-5=3
1*5=5
Now Add it all up.
45000+1500=46100
46100+3=46103
46103+5=46108
So, Your Answer is (C)
Your Welcome.
Answer:
D. 48
Step-by-step explanation:
In the experiment, 16/40 landed exactly on heads. If you do 16/40 * 3/3 = 48/120.
This means that you can estimate 48 of the next 120 trials have 2 coins showing heads.
The answer is -4. I solved it on a calculator and got -4
Answer:
option (a) It will be closer to 30 than to 20
Step-by-step explanation:
Data provided in the question:
For sample 1:
n₁ = 10
variance, s₁² = 20
For sample 2:
n₂ = 15
variance, s₂² = 30
Now,
The pooled variance is calculated using the formula,
on substituting the given respective values, we get
or
= 26.0869
Hence,
the pooled variance will be closer to 30 than to 20
Therefore,
The correct answer is option (a) It will be closer to 30 than to 20
