Answer:
68% of the distribution will be within one standard deviation of the mean
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
Bell-shaped = Normally distributed.
This means that 68% of the distribution will be within one standard deviation of the mean
Given that we have 47 kids and each kid needs 10 marbles, find out how many bags of 24 marbles will we need.
First, we will multiply 47 by 10 to get the amount of marbles needed.
47 x 10 = 470
So, that means we need 470 marbles in total.
Then, we divide 470 by 24 to see how many bags of 24 marbles 470 marbles is.
470 / 24 = 19.5833
Since, we can't have 19.5833 bags, we have to check what it would be if we only used 19.
19 x 24 = 456
470 - 456 = 14
Since, 18 is the closest number of bags but it has less than 470 it would not be correct.
Therefore, the best answer would be B. 25 since it is better to have extra marbles but not a very wide margin.
The total salary juma receives for the month of July before the deductions is sh. 12,800
<h3>Amount of earnings</h3>
Let
- Total salary = x
- Amount spent on school fees = 1/2x
- Amount spent on farming = 1/8x
School fees + farming = 1/2x + 1/8x
= 4x+x/8
= 5/8x
Amount remaining = x - 5/8x
=8x-5x /8
= 3/8x
Amount spent on food = 2/3 × 3/8x
= 6/24x
= 1/4x
So,
1/4x = sh.3200
x = 3200 ÷ 1/4
x = 3200 × 4
x = sh. 12,800
Complete question:
