Jordan is saving his money to buy a new pair of shoes.
.the shoes costs $360.
.he currently has $90 saved.
.he earns $50 a week mowing lawns.
how long will it take jordan to save up enough money
jordan to save up enough money to buy the shoes?
a 5 weeks
b 4 weeks
c 6 weeks
d 3 weeks

It will take Jordan 6 weeks (C) to save up enough money for him to buy the shoes.

Step-by-step explanation:

Step 1: $360 minus the $90 he already has saved up.

Step 2: Take the $270 and divide it by 5, which will give you 250. That is not enough, therefore you then divide 270 by 6 and you then get $300. That is more than what is needed to make up the defecate for him to buy the shoes that he wants. Therefore, the answer is "C".

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
