12 girls out of 30 were selected, so the ratio "selected:tried" if 12/30. This fraction can be simplified into

\dfrac{12}{30} = \dfrac{2}{5}

Similarly, 16 boys out of 40 were selected, so the ratio "selected:tried" if 16/40. This fraction can be simplified into

\dfrac{16}{40} = \dfrac{2}{5}

So yes, the ratio of the number of students on the team to the number of students trying out the same for both boys and girls

One side of a square is 3x + 2. Which expression represents the perimeter?
MissTica

Your answer would be 12x + 8 because there are 4 sides to a square and they are all 3x + 2, so you would need to multiply 3x + 2 by 4 which you can do by expanding brackets which gives you 4(3x + 2) and thus when you multiply it out you get 12x + 8. I hope this helps!

A consumer organization estimates that over a​ 1-year period 20​% of cars will need to be repaired​ once, 8​% will need repairs​
Sladkaya [172]

Answer:

Probability that a car need to be repaired​ once = 20% = 0.20

Probability that a car need to be repaired​ twice = 8% = 0.08

Probability that a car need to be repaired​ three or more = 2% = 0.02

a) If you own two​ cars what is the probability that  neither will need​ repair?

Probability that a car need to be repaired​ once , twice and thrice or more= 0.20+0.08+0.02=0.3

Probability that car need no repair = 1-0.3=0.7

Neither car will need repair=0.7 \times 0.7=0.49

​b) both will need​ repair?

Probability both will need​ repair = 0.3 \times 0.3=0.09

c)at least one car will need​ repair

Neither car will need repair=0.7 \times 0.7=0.49

Probability that at least one car will need​ repair= 1-0.49 = 0.51

Determine the value of base b if (152)b = 0x6A. Please show all steps.
DaniilM [7]

Assuming 0x6A is given in base 16, first convert 152_b and 6A_{16} to a common base, say base 10:

152_b=1\cdot b^2+5\cdot b^1+2\cdot b^0=(b^2+5b+2)_{10}

6A_{16}=6\cdot16^1+10\cdot16^0=106_{10}

Then

b^2+5b+2=106

b^2+5b-104=(b-13)(b+8)=0

\implies b=13
