Answer:
3781
Step-by-step explanation:
80 hours × $18=$1440 for labor. 1440+15%(1440×.15)=$216.00 + material cost=$2125
(2125.00+1440.00+216=3781)
The confidence interval is from 9.81 to 10.19.
We first find the mean of the data:
<span>(9.8+10.2+10.4+9.8+10.0+10.2+9.6)/7 = 10
Next we find the standard deviation:
</span>σ=√([<span>(9.8-10)^2+(10.2-10)^2+(10.4-10)^2+(9.8-10)^2+(10-10)^2+(10.2-10)^2+(9.6-10)^2]/7) = 0.262
The z-score for 95% confidence is found by
1-0.95 = 0.05; 0.05/2 = 0.025; from the z-table, it is 1.96.
The confidence interval is calculated using
</span>

<span>
</span>
just count by 60's until you get close to 852 and each 60 is 1 bracelet
Answer:
7
Step-by-step explanation:
pq - r/4
(-8)(-3) - 68/4
-8 x -3 = 24 (2 negatives equal a positive)
24 - 68/4
68/4 = 17
24-17 = 7
Answer: 135%
Step-by-step explanation: Given
Europe = 35%
Asia = 10%
Australia* = 20%
North America = ?
To find
Europe + Asia + Australia =
35% + 10% + 20% = 65%
Then the total subtracted from the given
200 - 65 = 135
Therefore,
North America = 135%
Confirm
To make sure that is the correct answer, add it all together.
35 + 10 + 20 + 135 = 200
Which means it is correct.
