Let
L=event that a selected worker has low risk
H=event that a selected worker has high risk
We need to find
P(HL)+P(LH)
=5*20/(25*24)+20*5/(25*24)
=1/6+1/6
=1/3
Angle 1: 33, Angle 2: 147
Step-by-step explanation:
If I have angle x, and its supplement angle is 3 times its supplement increased by 48 degrees, then I know the following:
Angle 1 = x
Angle 2 = 3x+48
Both of these angles add to 180 degrees.
x+(3x+48)=180
= 4x+48=180
=4x=132
=x=33, Angle 1 = 33 degrees
So angle 1 is 33 degrees
that should mean that angle 2 is 147
Answer:
50
Step-by-step explanation:
30 + 20 first you add 0 + 0 = 0 now you has 3 + 2 = 5 put them togeter 50

Answer:
it will take Larissa 4 17/27 hours to finish 5lbs of goldfish
Step-by-step explanation:
1.5 pound = 1 1/2 pound equivalent to 3/2 pounds
3/5 of a 1.5-pound
= 3/5 × 3/2 pounds
= 9/10 lbs of goldfish eaten in 5/6 hours
how long, in hours, would it take her to finish a 5-lb box of goldfish?
Find the ratio
9/10 lbs of goldfish : 5/6 hours = 5lbs of goldfish : t hours
9/10 ÷ 5/6 = 5 / t
Solve for t
9/10 × 6/5 = 5 / t
54 / 50 = 5 / t
Cross multiply
54 × t = 50 × 5
54t = 250
Divide both sides by 54
t = 250 / 54
= 4 34/54
= 4 17/27 hours
Therefore, it will take Larissa 4 17/27 hours to finish 5lbs of goldfish
