Answer:
39
Step-by-step explanation:
The sum of 34+5 is 39
Answer:
4a²+62a+49
Step-by-step explanation:
since (a+b)^2= a^2+2ab+b^2
(3a +7)² – 5a(a-4)
simplify the equation first
9a²+42a+49-5a²+20a
= 4a²+62a+49
Sin=opposite/hypotenuse
The opposite of B is 3 and the hypotenuse is 5.
Therefore the answer for 1 is D 3/5.
cos=adjacent/hypotenuse
The adjacent of B is 4 and the hypotenuse is 5.
Therefore the answer for 2 is B 4/5.
Answer:
The probability that 5 chosen bagels of which exactly 3 are Asiago cheese = 0.3087 or 30.87%
Step-by-step explanation:
Given:
Total bagels brought to school = 10
Number of Asiago cheese bagels = 7
To find the probability of randomly choosing 5 Asiago cheese bagels of which exactly 3 are Asiago cheese.
Solution:
Let probability of choosing an Asiago cheese bagel be the successful event.
Probability of choosing one Asiago cheese bagels =
Probability of success = 0.7
Probability of failure ( not choosing an Asiago cheese bagel) = 1 - Probability of success =
Using Bernoulli Trials
To calculate the binomial probability of obtaining exactly events in trials the formula used is:
⇒
where Probability of success
Probability of failure
Thus, probability of randomly choosing 5 Asiago cheese bagels of which exactly 3 are Asiago cheese can be calculated as :
