18 is what percent of 60?

2 answers:

4 0

F<span>irst you set up a proportion 18 over ? = 60 over 100 then cross multiply. 18*100=1800 then divide that by 60 and you get 30
or
</span>18/60=x
0.30=x
30
hope this helps!!!!

So 18 is x percent of 60
perctn means parts out of 100 so
x percent=x/100=
'of' can be translated to as multiply
18=x/100 times 60
18=60x/100
18=6x/10
multiply by 10
180=6x
divide by 6
30=x
the answer is 30%

7.4 Practice

The simulation of the medicine and the bowler hat are illustrations of probability

The probability that the medicine is effective on at least two is 0.767
The probability that the medicine is effective on none is 0
The probability that the bowler hits a headpin 4 out of 5 times is 0.3281

<h3>The probability that the medicine is effective on at least two</h3>

From the question,

Numbers 1 to 7 represents the medicine being effective
0, 8 and 9 represents the medicine not being effective

From the simulation, 23 of the 30 randomly generated numbers show that the medicine is effective on at least two

So, the probability is:

p = 23/30

p = 0.767

Hence, the probability that the medicine is effective on at least two is 0.767

<h3>The probability that the medicine is effective on none</h3>

From the simulation, 0 of the 30 randomly generated numbers show that the medicine is effective on none

So, the probability is:

p = 0/30

p = 0

Hence, the probability that the medicine is effective on none is 0

<h3>The probability a bowler hits a headpin</h3>

The probability of hitting a headpin is:

p = 90%

The probability a bowler hits a headpin 4 out of 5 times is:

P(x) = nCx * p^x * (1 - p)^(n - x)

So, we have:

P(4) = 5C4 * (90%)^4 * (1 - 90%)^1

P(4) = 0.3281

Hence, the probability that the bowler hits a headpin 4 out of 5 times is 0.3281

What is the answer to this?

GuDViN [60]

Answer:

$< 1 = 48$

Step-by-step explanation:

$< 1 + 132 = 180$

$< 1 = 180 - 132$

$< 1 = 48$

because it's a straight angle(180)
