Answer:
Obtuse
Step-by-step explanation:
square the 2 smaller side lengths. 10^2+11^2= 221. If you square the longer side length, you get 225. 15^=225.
An acute triangle is when the 2 smaller side lengths are greater
A right triangle is when the 2 smaller side lengths are equal
An obtuse triangle is when the 2 smaller side lengths are less.
221 is less than 225, making it obtuse.
f(x) = log2 x
f(40) = log2 40
40 = 2^y
2^5 = 32 and 2^6 = 64
so f(40) lies between integers 5 and 6.
Answer:
And using the probability mass function we got:
Step-by-step explanation:
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Solution to the problem
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
And we want to find this probability:
And using the probability mass function we got:
Answer:
it's 8
Step-by-step explanation:
(10×1/5)^3=2^3=8
Well 1+7 =8
And 7+1 are the same digits so 1+7=7+1=8
