At a stop sign, some drivers come to a full stop, some come to a rolling stop' (not a full stop, but slow down), and some do not

Natasha2012 [34]

Answer:

Option C.

Step-by-step explanation:

Given information:

Male-Full stop = 6, Male-Rolling stop = 16, Male-No stop = 4

Female-Full stop = 6, Female-Rolling stop = 15, Female-No stop = 3

Using the given information we get

Total number of males = 6 + 16 + 4 = 26

Total number of males = 6 + 15 + 3 = 24

Probability of No stop is

$p=\dfrac{\text{No-stop}}{Total}$

$p=\dfrac{4+3}{50}$

$p=\dfrac{7}{50}$

We need to find the number of males that would we expect to not stop at all.

Expected number of males = Number of males × Probability

Expected number of males = $26\times \dfrac{7}{50}$

Expected number of males = $3.64$

Therefore, the correct option is C.

Marie mixes 20 liters of 12% acid solution with a 36% acid solution to make a 20% acid solution. How many liters of 36% solution

kykrilka [37]

Use c1v1+c2v2=c3v3
where c=concentration, v=volume.

C1=0.12
V1=20 L
C2=0.36
V2=X
C3=0.20
V3=20+X L

Substitute in equation
0.12(20) + 0.36X = 0.20(20+X)
Expand
2.4 + 0.36X = 4 + 0.2X
Simplify
(0.36-0.2)X = 4-2.4
0.16X = 1.6
X=1.6/0.16 = 10 L

check:
0.12(20)+0.36(10)=2.4+3.6=6.0
(20+10)*0.20 = 6.0 so solution is good.

Answer: Volume of 36% solution is 10L

I<br> f the cost of 10 pens is rs 300,how much more is the cost of 2 dozens.

geniusboy [140]

➷ Find the cost per pen by dividing:

300/10 = 30

It costs rs 30 for one pen

1 dozen = 12

2 dozens = 24

Multiply the values:

24 x 30 = 720

The cost of 2 dozen pens is rs 720

However, as it is asking for 'how much more' you have to subtract:

720 - 300 = 420

The cost is rs 420 more

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^
