Answer:
C. 0.403
Step-by-step explanation:
Binomial distribution has two parameter n and p. Here, n=15 and p=0.60.
We have to find the probability of 10 or more will show that the hamburger, French fries and a drink were ordered. P(X≥10)=?
The binomial probability distribution function for random variable X is
![P(X=x)=nCxp^{x} q^{n-x}](https://tex.z-dn.net/?f=P%28X%3Dx%29%3DnCxp%5E%7Bx%7D%20q%5E%7Bn-x%7D)
where q=1-p=1-0.6=0.4,n=15 and p=0.6.
P(X≥10)=P(X=10)+P(X=11)+P(X=12)+P(X=13)+P(X=14)+P(X=15)
=0.185938
=0.126776
=0.063388
=0.021942
=0.004702
=0.000470
P(X≥10)= 0.185938
+0.126776
+0.063388
+0.021942
+0.004702
+0.000470
P(X≥10)=0.403216
So, the probability of 10 or more will show that the hamburger, French fries and a drink were ordered is 0.403.
Answer:
5.21
Step-by-step explanation:
(x2-x1)2 + ( y2-y1)2
(-3-1)2 + ( 2/3-4)2
16+ 11/1/9
square root of 27/1/9

<span>16407.
An integer is a whole number that doesn't need to be written using a fraction or decimals. (Some examples of integers are 4, 50, and -3; on the other hand, fractions or decimals like 1/2 or .3 are not).
Because we round up a number when the decimal is greater than or equal to .5 (which in this case it is), we round 16406.5 to the next biggest integer, 16407.</span><span />
