All together, 3 people have 120 coins. mark has 3 times as many as joel, and joel has 1/2 as many as sandra. how many coins does
oksano4ka [1.4K]
Joel = j, Mark = m, Sandra = s
j + m + s = 120
m = 3j
j = 1/2 s --> s = 2j
plug in (substitute) each letter to make it in terms of only j: j + m + s = 120
j + 3j + 2j = 120
6j = 120
6j/6 = 120/6
j = 20
now plug in for the j & s equation:
s = 2j = 2(20) = 40
Therefore Sandra has 40 coins!

Find the sum of the terms.
kow [346]

Answer:

C

Step-by-step explanation:

Given

\frac{x}{x^2+3x+2} + \frac{3}{x+1} ← factor the denominator of first fraction

= \frac{x}{(x+1)(x+2)} + \frac{3}{x+1}

Multiply the numerator/ denominator of second fraction by (x + 2)

= \frac{x}{(x+1)(x+2)} + \frac{3(x+2)}{(x+1)(x+2)}

The denominators are now common, so add the numerators leaving the denominator, that is

= \frac{x+3x+6}{(x+1)(x+2)}

= \frac{4x+6}{(x+1)(x+2)} → with numerator 4x + 6 → C

The average thickness of books on a library shelf is 8.3 centimeters. The standard deviation is 0.6 centimeter. If 20% of the bo
jeka57 [31]

Answer:

8.8 cm

Step-by-step explanation:

-We know that the top 20% of the books are oversized.

-We therefore find the z-value of the top 20%:

z_{0.1}=8.4

#We substitute the z value in formula to solve X.

z=\frac{\bar  X-\mu}{\sigma}

Where

  • X is the minimum thickness of the book.

-Given \sigma=0.6 \ , \mu=8.3, the minimum thickness,X can be calculated as follows:

z=\frac{\bar  X-\mu}{\sigma}\\\\0.84=\frac{\bar X-8.3}{0.6}\\\\\bar X=0.84\times 0.6+8.3\\\\=8.804\approx 8.8\ cm

Hence, the minimum thickness of the oversized books is 8.8 cm
