Answer:
Step-by-step explanation:
we have
Simplify
Multiply the expression by 
Apply difference of squares in the denominator
B) 200.96 because the area of a circle is 2*Pi* your radius which is 8 so you do 2 times 3.14 times 8 and you get 200.96 hope i helped!!
In throwing a dice, there are 6 possible outcomes, namely 1, 2, 3, 4, 5 and 6.
P=(no. of favourable outcomes)/(no. of possible outcomes)
When we multiply the probability of an event with no. of trials, the we get the expected frequency of that event.
1) P(getting 1)=1/6
expected frequency of getting 1
=P(getting)1)×no. of trials
=1/6×600=100
But it is given that one is scored 200 times, so it makes a large difference from expected frequency, which is 100.
Therefore, the dice is not fair.
2) P(getting a tail)=0.3
estimate for the number of times the coin will land on a tail
=expected frequency of getting a tail
=P(getting a tail)×no. of trials
=0.3×150=45
3)P(getting a six)=2/3
expected frequency of getting a six
=P(getting a six)×no. of trials
=2/3×300=200
4)P(getting a three)=0.5
expected frequency of getting a three
=P(getting a three)×350
=0.5×350=175
No, Chloe didn't cut the correct amount of fabric, because she needs 0.1125 extra fabric to account for error, as an extra 15% of 0.75 yards of fabric
Collect like terms so that the equation becomes 14x-44=180
Move negative 44 to the other side as a positive so equation becomes
14x=224
Divide both sides by 14
224/14 which is 16
So x is equal to sixteen
