Step-by-step explanation:
a. 6 £/hr
b. 6.8 £/hr.....is this right?
Answer:4/15
Step-by-step explanation:
1. multiply and divide (left to right)3/5
=3/5-1/3
2.multiply and divide (left to right) 1/3
=3/5-1/3
3.add and subtract (left to right) 3/5-1.3:4/15
=4/15
Answer:
9
Step-by-step explanation:
- Rewrite the problem
4x2-2(2)+5
2. Solve the problem. Do the multiplication first and then the subtraction and addition
8-2(2)+5
8-4+5
4+5
9
The final answer is 9
Answer:
4.01% probability that the battery will break down during the warranty period
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:

a. What is the probability that the battery will break down during the warranty period
Warranty of 2 years = 24 months. So this is the pvalue of Z when X = 24.



has a pvalue of 0.0401
4.01% probability that the battery will break down during the warranty period
