Answer:
#4, the answer is 9
Step-by-step explanation:
#4 GCF 18 and 63 is 9
#11 the answer is 9
The answer is 4!·3!=144
the ! is interesting. it goes like this:
1!= 1
2!=2
3!=6
4!=24
this happens because each ! will multiply the number by the answer to the number before it. it is easier to show you though.
1!=1 because 0!=1, and 1*1=1
2!=2 because 1!=1, and 2*1=2
3!=6 because 2!=2, and 3*2=6
4!=24 because 3!=6, and 4*6=24.
so 4!=[(24)*(6)]=3!
24*6=144
Answer: c. 39.14 to 42.36
Step-by-step explanation:
We want to determine a 95% confidence interval for the average hourly wage (in $) of all information system managers
Number of sample, n = 75
Mean, u = $40.75
Standard deviation, s = $7.00
For a confidence level of 95%, the corresponding z value is 1.96. This is determined from the normal distribution table.
We will apply the formula
Confidence interval
= mean +/- z ×standard deviation/√n
It becomes
40.75 +/- 1.96 × 7/√75
= 40.75 ± 1.96 × 0.82
= 40.75 + 1.6072
The lower end of the confidence interval is 40.75 - 1.6072 =39.14
The upper end of the confidence interval is 40.75 + 1.6072 =42.36
Answer:
The watermelon candies taste $0.13 more.
Step-by-step explanation:
First, in order to find out how much each candy costs per ounce, you have to take the cost and divide it by the number of ounces. 3.48 divided by 12 is 0.29, so the watermelon candies cost $0.29 per ounce. 1.38 divided by 8 is 0.16, so the chewy chocolates cost $0.16 per ounce. In order to find how much more the watermelon candies cost, we have to subtract the cost of the watermelon candies by the cost of the chocolate candies. 0.29-0.16=0.13, so the watermelon candies cost $0.13 more than the chocolate candies.
