(a) there are 8C2 = 28 ways of picking 2 girls from 8
And there are 21C4 = 5985 ways of picking 4 boys
Required number of ways for 2g / 4b = 28 * 5985 = 167,580
(b) at least 2 girls means combinations of 2g/4b , 3g,3b , 4g/2b , 5g 1b or
6 girls.
2g/4b = 167,580 ways
3g/3b = 8C3 * 21C3 = 56 * 1330 = 74,480
4g/2b = 8C4* 21C2 = 70 * 210 = 14,700
5g 1b = 8C5* 21 = 56*21 = 1176
6 girls = 8C6 = 28
adding these up we get the answer to (b) which is 257,964
First lets get 3% into decimal form.
3% is 3/100 = 0.03
Now multiply 0.03 by 47000 to get how much extra money she was going to get.
47000 * 0.03 = 1410
Now we just add
47000 + 1410 = 48410 is what she was going to make in 2012
Another way to do this is
(47000)(1+0.03) = 48410
you would use (1+0.03) which tells you she increased in pay.
Simple.
100% of the student body is 160 + 80, which is 240.
160 is 66.7% of 240.
So 66.7% voted for a bulldog.
Hope this helps!
By definition we have to:
d = v * t
where,
d: distance
v: speed
t: time
We have then that the speed is:
(360-210) = v * 2.5
Clearing we have:
v = (360-210) /2.5
v = 60 mph
We now write the generic equation of distance:
d (x) = 60x
Where,
x: time
Answer:
an equation that represents (x), the distance Ainsley is from Orlando after x hours is:
d (x) = 60x
Answer:
The distance the fish pulled the fishing line is <u>401.92 cm.</u>
Step-by-step explanation:
Given:
Radius of fishing spool = 4 cm.
Fish pulled on the line, and the spool spun 16 times before Bilal began to reel in the fish.
Now, to find the distance the fish pulled the fishing line.
So, to get the circumference of the spool first we put formula:
Radius(r) = 4 cm.
Value of π = 3.14.
<em>As given, fish pulled on the line, and the spool spun 16 times before Bilal began to reel in the fish.</em>
Now, to get the distance the fish pulled the fishing line, we multiply 16 with the circumference:
Therefore, the distance the fish pulled the fishing line is 401.92 cm.
