Simply the following 5 1/3 -7 5/6 + 6 1/4

lana66690 [7]

Answer:

$3 \frac{3}{4}\\$ / 3.75

Step-by-step explanation:

Step 1: Make all the mixed numbers, improper fractions:

$5 \frac{1}{3} = \frac{16}{3}$

$7\frac{5}{6} = \frac{47}{6}$

$6\frac{1}{4} =\frac{25}{4}$

In order to add/subtract fractions, they must all have a common denominator, the smallest common denominator for all these fractions is 12. And so in order to make 12 the denominator, we must now multiply all the fractions by their multiple.

$\frac{16}{3} = \frac{64}{12}$

$\frac{47}{6} = \frac{94}{12}$

$\frac{25}{4} = \frac{75}{12}$

Time to solve:

$\frac{64}{12} -\frac{94}{12} + \frac{75}{12} =$

$\frac{-30}{12} + \frac{75}{12} =$

$\frac{45}{12}$

Simplify:

$\frac{45}{12} = \frac{15}{4}$

Convert to a mixed number:

$3 \frac{3}{4}$

Hope this helps!

Merik had 24 hole muffins she gave 1/6 of them to her friends how many does she have left

Alenkinab [10]

She would have 20 muffins. 1/6 of 24 is 4, so subtract 4 from 24.
24-4=20.

Let x be a Poisson random variable with μ = 9.5. Find the probabilities for x using the Poisson formula. (Round your answers to

miv72 [106K]

Answer: 1

Step-by-step explanation: the probability mass function that defines a possion probability distribution is given below as

P(x=r) = e^-u × u^x/x!

For this question, x = 0 and u = 9.5

Hence we have that

P(x=0) = e^-0 × 9.5^0 / 0!

P(x=0) = 1 × 1/ 1 = 1
