We presume you want to add the two vectors.
<5, -2> + <0, 0> = ((5+0), (-2+0)> = <5, -2>
Answer:
Top left corner: 17 tiles are shaded, which is 85% of 20
Step-by-step explanation:
x/20 = 85/100
100x = 1700
100x/100 = 1700/100
x = 17
Answer:
The approximate probability that the total weight of the passengers exceeds 4432 pounds is 0.2709
Step-by-step explanation:
No. of passengers = n = 21
We are supposed to find the approximate probability that the total weight of the passengers exceeds 4432 pounds
Z=0.612
refer z table
P(Z<211)=0.7291
P(Z>211)=P(Z>4432)=1-0.7291=0.2709
Hence the approximate probability that the total weight of the passengers exceeds 4432 pounds is 0.2709
Answer:
34 Nickles 49 Quarters
Step-by-step explanation:
You have to give variables to the Quarters and Nickles (x and y)
Then you have to write corresponding equations based on the problem:
x+y=83
.25x+.05y=13.95
Then you would solve for y by isolating the x value in the first equation and plugging it into the second equation.
x=83-y ----> .25(83-y)+.05y=13.95
Solve for y
y=34
Then plug y into first equation to get quarters
