Answer:
78 Ft. ^2
Step-by-step explanation:
Cut it into two pieces, 6x2, and (15-9)x11, and solve.
1. 12
2. 66
Add: 66+12= 78!
Answer: Ten more than twice a number is 34.
Step-by-step explanation:
it would be ten plus 2 times x=34, but we dont know that number, so we replace it with a variable.
2x+10=34
Answer:
2°C and -2°C
Step-by-step explanation:
A number and its opposite sum to zero. (The "opposite" is the number with a minus sign instead of a plus sign, or vice versa.)
Answer:
c. binomial distribution with n = 5 and p = 1/33.
Step-by-step explanation:
For each birth, there are only two possible outcomes. Either it results in a defect, or it does not. The probability of a birth resulting in a defect is independent of other births. So we use the binomial probability distrbution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
The proportion of American births that result in a birth defect is approximately 1/33 according to the Centers for Disease Control and Prevention (CDC).
This means that the probability of a birth resulting in a defect is 
A local hospital randomly selects five births.
This means that 
So the correct answer is:
c. binomial distribution with n = 5 and p = 1/33.
The distance is the same. So the two conditions (driving there and driving back) can be equated.
There
t = 3 hours
d = d
r = 54 mph
Back
t = ?
d = d
r = 60 mph
Basic Formula
d = r * t
Solution
54 * 3 = 60 * t Combine the left side
162 = 60 * t Divide by 60 on both sides
162 / 60 = t Combine
2.7 hours = time coming back.
0.7 hours = 60 * 0.7 = 42 which is in minutes.
2 hours and 42 minutes. Answer
