Answer:
67.6
Step-by-step explanation:
first, to find the mean you add up all the numbers and you would get 338. Next, you divide by how many numbers there are (5) so 338 divided by 5 equals 67.6
Answer:
OPTION D
Step-by-step explanation:
It is given that the current in the circuit is given by V divided by the sum of t and T.
Denoting this mathematically we would have:
Now to solve for T rewrite the above expression.
⇒ T = - t
Therefore the answer would be Option D.
Claire receives 24 marbles. David gets 30 marbles and Elizabeth gets 36 marbles.
4x+5x+6x=90
15x=90
x=6
4(6)=24 for Claire
5(6)= 30 for David
6(6)= 36 for Elizabeth
Answer:
4 eggs
Step-by-step explanation:
Total eggs = 10
Boiled eggs = 3
Eaten eggs = 3
Note: Boiled eggs = eaten eggs because you can't eat eggs without boiling it first
Boiled eggs = eaten eggs = 3
Spoilt eggs = 3
Total eggs remaining = Total eggs - eaten eggs (Boiled eggs) - spoilt eggs
= 10 - 3 - 3
= 10 - 6
= 4 eggs
Total eggs left = 4
Answer:
d. No, the conditions for normality have not been met because the sample size for the pennies is not large enough and no information is given about the distributions of the populations.
Step-by-step explanation:
In this example, we learn that the sample taken of pennies was of 25, while the sample of quarters was of 35. According to the central limit theorem, a sample must be equal to or larger than 30 for the theorem to hold. The theorem states that when random variables are added, they tend towards a normal distribution even if the original variables themselves are not normally distributed. In this question, the sample of pennies is not large enough for the theorem to hold. On top of this, we have no information about the distribution of the populations. Therefore, the conditions for normality have not been met.
