What is the unit fraction of 9/10?

1 answer:

3 0

$\dfrac{9}{10}=\dfrac{1}{2}+\dfrac{1}{3}+\dfrac{1}{15}$

$\dfrac{1}{2}=\dfrac{15}{30}\\\\\dfrac{1}{3}=\dfrac{10}{30}\\\\\dfrac{1}{15}=\dfrac{2}{30}\\\\\dfrac{1}{2}+\dfrac{1}{3}+\dfrac{1}{15}=\dfrac{15}{30}+\dfrac{10}{30}+\dfrac{2}{30}=\dfrac{15+10+2}{30}=\dfrac{27}{30}=\dfrac{9}{10}$

A 12-sided die is rolled. The set of equally likely outcomes is {1,2,3,4,5,6,7,8,9,10,11,12). Find the probability of rolling a

levacccp [35]

Answer:

$P(x>12) = 0$

Step-by-step explanation:

Given

$x = \{1,2,3,4,5,6,7,8,9,10,11,12\}$ --- outcomes

$n(x) = 12$ -- sample size

Required

$P(x > 12)$

This is calculated as:

$P(x > 12) = \frac{n(x > 12)}{n(x)}$

$n(x>12) = 0$ because none of the outcomes is greater than 12:

So:

$P(x > 12) =\frac{0}{12}$

$P(x>12) = 0$

The sum of two numbers is 31.5. The difference is 5.25. Find the numbers

ANTONII [103]

X+y=31.5
x-y=5.25

add 2 equations
x+y+x-y=31.5+5.25
2x=36.75
x=18.375
y=31.5-18.375=13.125
check : 18.375+13.125=31.5, 18.375-13.125=5.25
so
Answer:
18.375 and 13.125
