Step-by-step explanation:
−42−5i 2y−1(y−2)(y−2)
Answer:
100 centimeters
Step-by-step explanation:
Area of a square is side x side= s x s or s²
If s² = 1 square meter
s = √1 = 1 meter
Each side is 1 meter. To convert to centimeters multiply by 100 since there are 100 centimeters in 1 meter.
Each side is 100 centimeters
27 quarters because 27 multiplied by $0.25 for the amount each quarter is worth is $6.75 meaning that the rest 41 coins would be Nickels multiplied by $0.05 the amount a nickel is worth giving us $8.80 dollars.
I probably said that in a confusing way sorry but the answer is (27 quarters)
Answer:
The GCF for the numerical part is 2
Step-by-step explanation:
6x^2y^2-8xy^2+10xy
It contains both numbers and variables, there are two steps to find the GCF(HCF).
1). Find the GCF for the numerical part 6, -8,10
2). Find the GCF for the variable part x^2,y^2,x^1,y^2,x^1,y^3
3).Multiply the values together.
Find the common factors for the numerical part:
6,-8,10
Factors of 6
6: 1,2,3,6
Factors of -8
-8: -8,-4,-2,-1,1,2,4,8
Factors of 10
10:1,2,5,10
Common factors of 6,-8, 10 are 1,2
The GCF Numerical=2
The GCF Variable= xy^2
Multiply the GCF of the numerical part 2 and the GCF of the variable part xy^2, and you'll get 2xy^2
Answer:
The probability that he answered neither of the problems correctly is 0.0625.
Step-by-step explanation:
We are given that a student ran out of time on a multiple-choice exam and randomly guess the answers for two problems each problem have four answer choices ABCD and only one correct answer.
Let X = <u><em>Number of problems correctly answered by a student</em></u>.
The above situation can be represented through binomial distribution;
where, n = number of trials (samples) taken = 2 problems
r = number of success = neither of the problems are correct
p = probability of success which in our question is probability that
a student answer correctly, i.e; p = 
= 0.75.
So, X ~ Binom(n = 2, p = 0.75)
Now, the probability that he answered neither of the problems correctly is given by = P(X = 0)
P(X = 0) = 
= 
= <u>0.0625</u>
