Step-by-step explanation:
For this case we know the following info given for the life of a Brand Q car battery:
Part a
For this case we can use the empirical rule and we know that we have 68% of the values within one deviation from the mean, and if we find the limits we got:
68% of all batteries will have a life between 45 months and 51 months.
Part b
From the empirical rule and we know that we have 95% of the values within one deviation from the mean, and if we find the limits we got:
95% of all batteries will have a life between 42 months and 54 months.
Let
x-------> yards of fabric used to make pillows
y-------> yards of fabric used to make curtains
T------> total yards of fabric
R-------> remaining yards of fabric
we know that
we have
