Answer:
Add total rolls:
The number of rolls is the height of each bar:
14 + 12 + 16 + 15 + 13 = 70
70 total rolls
The numbers greater than 3 are 4 and 5
4 was rolled 15 times and 5 was rolled 13 times
15 + 14 =28 Total times
The probability of that happening would be 28/70 which reduces to 2/5
The answer as a fraction is 2/5 which is 40% as a percentage.
IF your graph matches this data :)
If 18 inches is 20% less than the original length of the snake, then you can say that it is 80% of the original length. 18 inches ÷ 80% = 0.225, which would be 1% of the original snake. Now that you have 1%, all you need to do is multiply by 100 to get 100%, which is 22.5 inches, which is answer D. I hope this helps!
If Adam has 16.45 kg of flour and he uses 6.4 kg to make hot cross buns, then he has left
16.45 - 6.4 = 10.05 kg of flour.
If Adam wants to use the remaining flour to make 15 batches of scones, then each batch of scones requires
10.05 : 15 = 0.67 kg of flour.
Answer: each batch of scones requires 0.67 kg of flour.
Answer:
Step-by-step explanation:
Given that the lengths of the sides of a triangle are consecutive integers
Since side cannot be negative we can assume that the sides are
a, a+1 and a+2 where a>0
The largest angle is opposite side a+2 and smallest is angle opposite a
Using sine formula and the given information that the largest angle is twice the smallest angle
we get

Cross multiply to get

Since sin 2A = 2sin A cos A
we get

Answer:
The proportion follows normal distribution,
Mean u = 0.39
standard deviation σ = 0.0218
Step-by-step explanation:
Solution:-
- Lets assume the population proportion ( p ) to be the percentage of adult Americans who believe that marriage is now obsolete.
- We will check for normality:
Lets take, p^ = p (Mean proportion of the distribution)
- The condition of normality,
n*p*( 1 - p ) ≥ 10
Where, n : The sample size taken.
500*0.39*( 1 - 0.39 ) = 500*0.39*( 0.61 )
118.95 ≥ 10
- Hence, with the testing statistics the condition for normality are validated. Hence, the distribution for proportion of adult americans who believe that marriage is now obsolete follows a normal distribution.
- The parameters of the distribution are:
Mean : u = p^ = p = 0.39
Standard deviation σ =
=
