Answer:
$4.32
Step-by-step explanation:
8% can be represented as 1.08
2 x 1.08 = 2.16
2 x 1.08 x 1.08 = 2.33
2 x 1.08 x 1.08 x 1.08 = 2.52
etc. all the way up to 10
Take for example the function y = 2x + 3
In order to shift this function 4 units to the right, we must subtract from the first term.
The new function would be y = (2x - 4) + 3
Answer:
<h2>The probability of being all females is 60%.</h2><h2>The probability of being all males is 40%.</h2>
Step-by-step explanation:
We know that 40% of the population is male.
If someone selected 9 students, the probability of being all males is 40%. But, the probability of being all females is 60%, because there are only two genders and females represents the complete set of the given probability.

Answer:
a) The equation is:
Confidence Interval = Mean ± Z score × Standard deviation/√Number of samples
b) The 98% confidence interval = (5.62784, 6.37216)
Step-by-step explanation:
a. Write down the equation you should use to construct the confidence interval for the average number of days absent per term for all the children. (10 points)
Confidence Interval = Mean ± Z score × Standard deviation/√Number of samples
b. Determine a 98% confidence interval estimate for the average number of days absent per term for all the children. (10 points)
Confidence Interval = Mean ± Z score × Standard deviation/√Number of samples
Mean = 6 days
Standard deviation = 1.6 days
Number of samples = 100
Z score of 98% confidence interval = 2.326
Confidence interval = 6 ± 2.326 × 1.6/√100
= 6 ± 2.326 × 1.6/10
= 6 ± 0.37216
= 6 - 0.37216
= 5.62784
6 + 0.37216
= 6.37216
Therefore, the 98% confidence interval = (5.62784, 6.37216)
