Equation t= $7 times w
$7 times 4 = $28
Answer:
12 presents
Step-by-step explanation:
4/6= 2/3
2/3 x 18 = 12
Answer:
12.2%
Step-by-step explanation:
Her total paycheck minus her salary = the commission amount
So
6500 - 1000 = 5500
So....her commission as a percentage of sales = 5500/ 45000 = about 12.2%
The confidence interval formula is computed by:
Xbar ± Z s/ sqrt (n)
Where:
Xbar is the mean
Z is the z value
S is the standard deviation
N is the number of samples
So our given are:
90% confidence interval with a z value of 1.645
Sample size 40, 45
Mean 180, 179
Standard deviation 2, 4
So plugging that information in the data will give us a
confidence interval:
For 1:
Xbar ± Z s/ sqrt (n)
= 180 ± 1.645 (2 / sqrt (40))
= 180 ± 1.645 (0.316227766)
= 180 ± 0.520194675
= 179.48, 180.52
For 2:
Xbar ± Z s/ sqrt (n)
= 179 ± 1.645 (4 / sqrt (45))
<span>= 179 ± 1.645 (0.596284794)</span>
therefore, the answer is letter b
Answer:
58 degrees or [30, 88]
Step-by-step explanation:
In such a context, the word "range" can have different meanings. On the one hand it is the difference between high and low:
88 -30 = 58 . . . . range of temperatures
__
On the other hand, it is the interval between (and including) the high and low:
[30, 88] . . . . temperature range
