Answer:
he is incorrect the answer is -4
Step by step explanation:
![\sqrt[3]{-8^{2} } \\\\\\\sqrt{-2^{2} } \\\\= -4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B-8%5E%7B2%7D%20%7D%20%20%5C%5C%5C%5C%5C%5C%5Csqrt%7B-2%5E%7B2%7D%20%7D%20%5C%5C%5C%5C%3D%20-4)
just because something is negative doesn't mean it cant still be divided
it will still be able to be divided but it will be a negative number
Answer: B. x ~ B(50, .1)
In other words, it's the second answer choice
===========================================================
Explanation:
We have n = 50 people in the sample and p = 0.10 is the decimal form of 10%, to represent the probability of success. In this case, we define "success" as "the person passes the fitness test".
The random variable x is the count of how many people pass. So we could have x = 0, x = 1, x = 2, ..., x = 49, x = 50. Basically any whole number from 0 to 50 inclusive. Furthermore, x is approximately modeled by the binomial distribution which we denote as B(n, p) = B(50, 0.1)
So X ~ B(50, 0.1)
Hello.
The answer is: 17.25
To get the answer
Hockey cards: x= 6y
baseball cards: x + y = 525
if u add them both you get 75 and 450 then times by 6
= 450 * .03+ 75 * .05
Have a nice day
