They had 17/12 ( 17 over 12, or 1 and 5 over 12)
So the fractions have to have the same denominator. 12 is their common denominator. So:
3/4 = 9/12
2/3=8/12
8/12+9/12= 17/12 or 1 and 5/12
Answer:
Step-by-step explanation:
1 km = 1000 meters
5 km = 5*1000 = 5000 meters
5 km and 5000 meters both measure the same length.
Answer:
2x + 2y = 4 does not belong
Step-by-step explanation:
2x + y = 4 → <u>y = -2x + 4</u>
y = -2x + 4 → <u>y = -2x + 4</u>
f(x) = -2x + 4 → <u>y = -2x + 4</u>
2x + 2y = 4 → <u>y = -x + 2</u>
Find the GCF of 45, 90, 75: which is 15
So he can make 15 stones total.
Divide each of the color numbers by 15 to get the number of tiles he uses in each stone
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
