Answer:
wiat ill work this out for you
Step-by-step explanation:
Question seem incorrect because 60%,50% and 20% sum up to more than a 100% therefore we've made a little correction
Answer:
0.8
Step-by-step explanation:
Probability = number of favorable outcomes/number of outcomes
Given that 30% are entertained by reading books
50% are entertained by watching TV
20% are entertained by reading books and watching TV
The probability that a person will be entertained by books or TV =
30/100+50/100= 3/10+5/10
=8/10
=0.8
Answer:
4.2kg
Step-by-step explanation:
She feeds her dog .12 a day, so for a month, I would multiply by 30 or 31
(both will give you the same answer).
After doing that , you get 3.6 (I multiplied by 30)
The other 2 options are less than that.
Hope this helps!
First make fractions.
2 5/7 = 19/7
3 4/5 = 19/5
19/7*x=19/5
Multiply 7 to other side (7*19/5=133/5)
Multiply 5 to other side (5*19=95)
95x=133
133 divided by 95 yields 1.4
The answer is 1.4
PART A
Coefficient
Coefficient h is 7.50
Coefficient s is 0.20
Variable
h and s
Constant
40
PART B
7.50h + 0.20s + 40
= 7.50(25) + 0.20(300) + 40
= 187.5 + 60 + 40
= 287.5
She earns $287.5
PART C
Yes, the coefficient of h would change to 9, the rests are still the same. Because she's no longer receive 7.50 per hour, and start earning 9 per hour, so the coefficient should change.
The expression would be
9h + 0.20s + 40
