Answer:
14 nickels
7 dimes
Step-by-step explanation:
1. find out how many dimes there has to be to get $1.40
1 dime= .10
1.40/.10=14 dimes
14/2=7
so there are 7 dimes
since a nickel is half the amount of a dime there will be twice as many to make up the other half which is $0.70
.70/.05=14
there are 14 nickels
proof:
$0.10(7)+$0.05(14)= $1.40
hope this helps!
For n=2,
put the value 2 in the above equation we get 525*2=1050°.
1050° angle takes 2 complete revolution and then makes an angle of 330° which will fall in the negative portion of y-axis.
For n=6,
put the value 6 in the above equation we get 525*6=3150°.
3150° angle takes 8 complete revolution and then makes an angle of 270° which will fall along negative y-axis.

ANSWER
5.2387 and 5.2437
EXPLANATION
To round a decimal to the nearest hundredth means we should round to two decimal places.
To round to two decimal places we consider the third decimal place.
When we round 5.2387 to the nearest hundredth, we obtain 5.24 because the third decimal place is greater than or equal to 5 so we round up.
When we round 5.2437 to the nearest hundredth, we get 5.24 because the third decimal place less than 5 so we round off.
In fact there are infinitely many decimals that will round to 5.24 when rounding to the nearest hundredth.
Step-by-step explanation:
P(X=1) = P(first heads and second tails) +P(first tails and second heads)
=P(first heads)×P(second tails) + P(first tails) ×P(second heads)
because events are independent P(A∩B) = P(A) ×P(B)
= 0.6 ×0.3 + 0.4 ×0.7
= 0.46
P(X=0) = P(first tails and second tails)
= 0.4 ×0.3
=0.12
P(X=2) = P(first heads and second heads)
= 0.6 ×0.7
= 0.42
Mean E(X) = 0 ×0.12 + 1 × 0.46 + 2 ×0 0.42
=1.3 ( Because mean is ratio it can can be greater than 1 )
