Answer:
x= -11
Step-by-step explanation:
distribute the 3 and the 2: 3 - 9x = -8x + 14
add 9x from both sides and subtract 14 from both sides: -11 = x
x = -11
The probability of a success on each roll of the coin that is filipped by Dion is 0.5.
<h3>What is the probability?</h3>
Probability is the likelihood that a stated event would occur. The odds the event occurs is 1 and the odds that the event does not happen is 0. If a coin is flipped, there is 50% chance of getting either a head or a tail.

Answer:
a) correct option is
Poisson distribution is 6.2 and standard deviation is 2.49
b) probability for only 2 or less than 2 surgeries in a given day is 0.0536
Step-by-step explanation:
Given data:
mean number is given as 6.2
correct option is
Poisson distribution is 6.2 and standard deviation is 2.49
we know that variance is given as
hence, standard deviation is given as 
thus standard deviation is 2.49
correct option is
Poisson distribution is 6.2 and standard deviation is 2.49
b) probability for only 2 or less than 2 surgeries in a given day is


= 0.002029 + 0.012582+ 0.039006
= 0.053617
= 0.0536
Answer:
- 1.6
Step-by-step explanation:
If divide these to numbers without the negative, you'll get 1.6
Then you can add the negative sign to the 50 and 1.6 and you'll get the correct answer... btw I'm just lazy and that's my way of dividing negative numbers.
Answer:
29 and -18
Step-by-step explanation:
f(x)= -3x+12
f(-9)= -3(-9)+2
f(-9)= 27+2
f(-9)= 29
g(x)= x2
g(-9)= -9(2)
g(-9)= -18
