Answer:
Step-by-step explanation:
Chris earns the commission on the jewelery sales. To calculate what he earned, multiply the commission rate and his sales.
His rate is 4% and his sales are $1,370
Convert the percent to a decimal. Divide by 100 or move the decimal two spots to the left.
- 4/100= 0.04
- 4.0 --> 0.4 --> 0.04
Chris's commission is <u>$54.80</u>
Answer:
b. 98
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find M as such
In which is the standard deviation of the population and n is the size of the sample.
In this problem, we have that:
So a sample of at least 98 is required.
The correct answer is:
b. 98
Answer:
Step-by-step explanation:
let x represent the number of markers.
Let y represent the cost for x boxes of markers.
If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be
Slope, m = (14 - 7)/(24 - 10)
m = 7/14 = 0.5
The equation of the straight line can be represented in the slope-intercept form, y = mx + c
Where
c = intercept
m = slope
To determine the intercept, we would substitute x = 24, y = 14 and m = 0.5 into y = mx + c. It becomes
14 = 0.5 × 24 + c = 12 + c
c = 14 - 12
c = 2
The equation would be
y = 0.5x + 2
Answer:
coefficent of 18 and degree 3
Step-by-step explanation:
Suggestion, order by highest to lowest degrees. 18x^3+6x^2+x-10.
There are 2 options for the coin
4 options for the religion
First lets make fraction
4 options: 1/4
2 options: 1/2
For a chinese:
1/2*1/4=1/8
the answer would be D, 1/8
