Answer:
A. 2/5
B. 1/10
Step-by-step explanation:
First off we need to calculate the probability that the chosen child is a girl So to calculate this probability, we have to know the num. of girls which is seen in the table. There are a total of 8 girls.
Therefore the probability of a girl being chosen is equivalent to the number of girls/exact number of children = 8/20 = 2/5 simplified.
Now to find the probability that the chosen girl is left-handed.
The amount of left-handed girls there is only 2. therefore the probability of selecting a left-handed girl will be 2/20 = 1/10 simplified.
If bill rides his bike at an average speed of 5 mph it will take 13 hours
For the denominator of 12, Your fractions will now look like:
8/12 ( Simplify if needed) as well as
9/12 (Simplify if needed)
You want to find the multiple that will give you 12 upon the bottom of the fraction and divide your numerator by that number as well. For the first one, it’s 3, and for the second one, it’s 6
Answer:
A. -1
Step-by-step explanation:
2x⁴ - 7x³ + 4x² + 7x - 6
2(1) - 7(-1) + 4(1) + 7(-1) - 6
2 + 7 + 4 - 7 - 6 = 0
6 + 7 - 7 - 6 = 0
2(256) - 7(64) + 4(16) + 7(4) - 6 = 0
512 - 448 + 64 + 28 - 6 = 0
604 - 454 is not equal to 0
2(625) - 7(125) + 4(25) + 7(5) - 6 = 0
1385 - 881 is not equal to 0
