Answer:
<h2> The answer is </h2><h2> D. 8x^2+4xy</h2>
Step-by-step explanation:
We know that the expression for the perimeter is given as
P=2l+2B
now given that the value of the width is =2x
length= 4x
and the breadth=y
P=4x+2y
let us multiply both the length and the width with 2x we have
P=2x(4x+2y)
P=8x^2+4xy
the answer is
D. 8x^2+4xy
Answer:1,0.5, or 0 it depends
Explanation:
The probability that one event occurred depends on the total of random event, being 1 the most of the probabilities
If the two marbles are blue the probability to select a marble blue is 1
If one of the marbles is blue and the other marble is of any color the probability to select the blue marbles is:
P=1 - 1/2=1/2
Being 1/2 or 0.5 the answer
If any of the marbles are blue then the probabilities are 0
Answer:
B is your answer. the reason is because the functions itself is negative
Answer:
The probability that Jones is lying is 6/7
Step-by-step explanation:
First we will list out 2 different cases when the outcome is a lie
1.probability that Jones tells lies is = 0.6 and probability that dalgiliesh analyses it correctly is 0.8
So the probability that dagliesh correctly analyses that he is telling lies is 0.8*0.6=0.48
2.Probability that Jones tells truth is 0.4 and if dagliesh analyses it incorrectly (which has a probability of 0.2) the outcome(as analysed by dagiliesh) is a lie
So probability that dagliesh analyses Jones truth as a lie is 0.2*.0.4=0.08
Total probability of outcome being a lie is 0.48+0.08=0.56
But we need the probability of Jones actually saying a lie which is nothing but 0.48/0.56= 6/7
Answer:
Step-by-step explanation:6/5
