Answer:
$561, yes!
Step-by-step explanation:
after 4 weeks, they will have 21*4=$84 per kid (4 kids). Therefore we need to multiply this by 4. 84*4=$336. You must remeber that they started with $225, so 225+336=$561, which is more than $512, so they can pay for the trip!
24000000. 1000000*24= 24000000, therefore, a million days ago in hours would be 24000000.
Cut it up
3.
left rectangle and right rectangle
left recgnale is 2 height, 3 width 6 legnth
V=6*3*2=36
right rectangle is 2 height 2 width and 4 legnth
V=4*2*2=16
add them 36+16=52ft^2
5. we can't se how widt the small right side is because you didn't capture that
Answer:
2.5% chance of finding a defective headset
970
Step-by-step explanation:
3% of the headsets found defective.
If 280 units of that model are tested, and the manufacturer finds 273 headsets without any defects,
easy to find percent 273/280=0.975
multiply by 100
97.5 then get 100-97.5=2.5
2.5% chance of finding a defective headset
ok 1,000 units of empirical probability
so the good ones
1,000/100=1
10= 1 percent
10*97=970
970
