How to simplify 27/8

katen-ka-za [31]

Well if you want to simplify you can do it to ways
1 leave it how it is because you cant simplify anymore
or
2 turn it into a mixed number
first see how many times you can fit 8 into 27
8*2=16 8*3=24 8*4=32
so it is 3 times
and you have 3 left over so that goes over 8 and your simplification is 3 3/8

Find the volume make it an improper fraction then a mixed number please do a step by step explanation and I will give you brainl

Andrews [41]

Answer:

8463/32=264 15/32

Step-by-step explanation:

Let's make every fraction improper first.

7 3/4=31/4

5 2/8=42/8

6 1/2=13/2

Simplify 42/8

42/8=21/4

21/4

31/4

13/2=26/4

21/14*31/4*26/4=(21*31*26)/64=16926/64=8463/32

In a study of 259 comma 995 cell phone users, it was found that 121 developed cancer of the brain or nervous system. Assuming t

IRISSAK [1]

Answer:

The probability of having 121 cases or less is:

$P(X$

This suggests that the study does not show any significantly effect of the use of cell phone in the probability of having brain or nervous system cancer. The use of cell phone does not appear to be a significant factor in the risk of having this type of cancer.

Step-by-step explanation:

We start by calculating the expected standard deviation of the population cases:

$\sigma=\sqrt{n\pi(1-\pi)}=\sqrt{259,995*0.000489*0.999514}\\\\\sigma=\sqrt{126.29}\\\\\sigma=11.24$

Then, to calculate the probability, we first calculate the z-score for 121 cases.

$z=\dfrac{X-\mu}{\sigma}=\dfrac{121-127}{11.24}=\dfrac{-6}{11.24}=-0.5338$

The probability of having 121 cases or less is:

$P(X$

This suggests that the study does not show any significantly effect of the use of cell phone in the probability of having brain or nervous system cancer. The use of cell phone does not appear to be a significant factor in the risk of having this type of cancer.

With 2.1 million digital subscribers, a top-ranked magazine has 1140% more digital subscribers than a magazine ranked third.

Mashcka [7]

Answer:

The answer is 201,923 subscribers

Step-by-step explanation:

Let the Top ranked magazine number of digital subscriber be t, and the number of the third most ranked digital subscriber be x,

Since the Top magazine has 1140% more than the third, this equation can be expressed as,

((t-x)/x)×100=1140

Substituting t=2.1×10^6, solve for x

(((2.1×10^6)-x)/x)×100=1140

Solving for x=201,923
