I believe this problem has 3 questions:
a. Explain why the three conditions are satisfied for X to have
the binomial distribution.
b. Identify n and p for the binomial distribution.
c. Find the probability that the family has two girls and
two boys.
Answers:
a. First because there are only 2 possible outcomes for
each birth: male or female. Hence a binomial distribution. <span>
Second, because the probability of giving out a girl is
constant: 0.49 for each birth.
Third, the probability of a giving out a girl does not depend
on whether or not there is already a boy or a girl in the family. </span>
b. The n is the total number of children, so n = 4
While the p is the success of being a girls, so P = 0.49
c. We use the binomial probability equation:
P (X) = nCx * p^x * q^(n-x)
<span>P(X=2) = 4!/(2!2!) * 0.49^2 * 0.51^2 = 0.3747</span>
<span>i would say its like a 125cc engine so 50mph 45-55 mph if cart no more than 250 lb.s -m This is wrong. I have a 11 hp go kart and it is 388cc and so it goes alot faster. well engines have so many rpms so the size does not matter but you can gear a bigger engine to make it go faster</span>
Answer:
8,7,11,7.5,10000 any number that is 7, or bigger!
Step-by-step explanation:
The slope of a line is defined as rise by run i.e. how much y value changes with respect to the change in x value. So the slope gives the steepness of the line.
Slope 0 indicates there is no change in y when the x value is changed and so the line with slope 0 is a horizontal line. A line with slope 1 shows with 1 unit change in x, y changes by 1 unit. Likewise slope equal 2 indicates with 1 unit change in x, y changes by 2 units.
We can see as the absolute value of slope is increasing, the change in y with respect to x is increasing i.e. the line is becoming more tilted or steep.
Hence, we can conclude that:
The graph of a line gets Steeper as the absolute value of the slope gets bigger.
C is the correct answer.
She took 100, the store has - 100
she went back and bough
70 bucks in stuff, the store has - 70
yes, she took the $100 bill and gave it, got back $30, that means she only kept $30 from the original bill.
the store however, lost the original $100 bill plus the $70 in merchandise, so they have -$170.
