Answer:

The answer is C) car b travels 11 more miles than car a in one hour

Step-by-step explanation:

Car A: 18/20(60)=54 mph

Car B: 13/12(60) = 65 mph

A nationwide survey of seniors by the University of Michigan reveals that almost 18.0% disapprove of daily pot smoking. If 8 sen

UNO [17]

Answer:

$P(X\geq 2)=1- P(X$

And using the probability mass function we can find the individual probabilities:

$P(X=0)=(8C0)(0.18)^0 (1-0.18)^{8-0}=0.2044$

$P(X=1)=(8C1)(0.18)^1 (1-0.18)^{0-1}=0.3590$

And replacing we got:

$P(X\geq 2)=1 -[0.2044 +0.3590]= 0.4366$

Then the probability that at least 2 disapprove of daily pot smoking is 0.4366

Step-by-step explanation:

Let X the random variable of interest "number of seniors who disapprove of daily smoking ", on this case we now that:

$X \sim Binom(n=8, p=0.18)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

And we want to find this probability:

$P(X\geq 2)=1- P(X$

And using the probability mass function we can find the individual probabilities:

$P(X=0)=(8C0)(0.18)^0 (1-0.18)^{8-0}=0.2044$

$P(X=1)=(8C1)(0.18)^1 (1-0.18)^{0-1}=0.3590$

And replacing we got:

$P(X\geq 2)=1 -[0.2044 +0.3590]= 0.4366$

Then the probability that at least 2 disapprove of daily pot smoking is 0.4366

What are the zeros of this function? (pictured above) How do you know?

arlik [135]

Answer:

x=-1 and x=3

Step-by-step explanation:

The zeroes of a function are its x-intercepts when the function passes through the x-axis. In this case, the parabola passes through (0,-1) and (0,3) which means the x-intercepts are x=-1 and x=3, which are also the zeroes.

Gordon earns 12% commission as a salesperson. He sold a playground slide that cost $270. How much commission did Gordon earn?

Rudiy27

Answer:

Step-by-step explanation:

so he gets a 12% commission on his sales. He sold a slide that costs 270.

so he would get 12% of 270

turn ur percent to a decimal..." of " means multiply

0.12 * 270 = $ 32.40 <===
