<span>He should use pounds.
Explanation<span>:
A bowling ball as we know it is an American item. In Britain, bowling most commonly means "lawn bowling," which uses different equipment. A bowling ball would be for the ten-pin bowling Americans enjoy. Since it is an American sport, we would not use the metric system; instead, we would use pounds.</span></span>
Answer:
A. (3,-4)
Step-by-step explanation:
if we reflect on the x axis, the y changes
if we reflect on the y axis, the x changes
The z-score is the number of standard deviations away from the mean that a data point is. To find the value of z for which 0.9426 of values are within z deviations of the mean, this means that (1 - 0.9426) = 0.0584 are beyond this interval, and this would be divided by 2: 0.0584 / 2 = 0.0292 of values are located below -z, while another 0.0292 is above +z.
Based on z-tables, this occurs at around z = 1.89, so the interval is from -1.89 to 1.89.
We can solve this by setting up a system of equations. We will use x for the $3 boxes and y for the $5 boxes:
x+y=34
3x+5y=130
We can use the elimination method by multiplying the first equation by 3:
3x+3y=102
3x+5y=130
0x-2y=-28
y=14
We can then plug this number back into one of the original equations to solve for x:
x+14=34
x=20
We can check these answers by plugging them into the equations:
20+14=34
34=34
(3)(20)+(5)(14)=130
60+70=130
130=130
Therefore, there are 20 of the $3 boxes, since we originally said that x would be the $3 boxes.
Answer:
Step-by-step explanation:
We have the following solution:
We want to find the value of x that satisfies the following condition:
y(3) = 3.
This means that when x = 3, y = 3. So
