2/3(x-7)=-2
2/3x-14/3=-2
2/3x=-2+14/3
2/3x=-6/3+14/3
2/3x=8/3
3/2(2/3x)=8/3(3/2)
6/6x=24/6
x=4
Answer:
P(X=2)=0.0446
Step-by-step explanation:
If X follows a Poisson distribution, the probability p to have x pits in 1 cm2 is calculated as:
Where m is the mean of pits per cm2, so, replacing m by 6 pits per cm2, we get that the probability is equal to:
Now, the probability P(x=2) that there are 2 pits in a 1 cm2 is calculated as:
The ratios of bats to balls would be the number of bats over the number of balls:
15/12
This can be reduced because both numbers are multiples of 3, so divide each one by 3:
15/12 = 5/4
Answer: 5/4
Answer:
x = 41 degrees
Step-by-step explanation:
supplement of 73 = 107 degrees
x = 180 -107 - 32 = 41 degrees
Answer:
The first step would be to look at the first two numbers (which is 27) and estimate which <u>multiple</u> of 5 is closest and <u>below</u> 27.
5*5 = 25
So once she got 25, she will need to subtract 27-25, which will give her 2. REMEMBER: 5 is the first number of the quotient.
Now, she will need to drag the last digit left of 275 (which is 5) to the remainder 2 and think what multiple of 5 will give her the answer 25.
Again, 5*5 = 25
Once again, her numbers on the quotient will be 55. That's the answer.
