Preliminary:

Fractions in Mathematics are rational numbers that can be written in the form x/y, where x and y are integers, and y 0 and the number x is not a multiple of y. In fractions x is called the numerator while y is called the denominator.

Fraction Types:

  • Common Fraction = is a fraction expressed in the form x/y, x as the numerator and y as the denominator. x and y are integers and y 0
  • Mixed fraction = is a combination of whole numbers and fractions, expressed in the form a \frac{b}{c}
  • Decimal fractions are indicated by a comma (,) as a separator between the round and fractional parts. The round part is in front of the comma and the fraction part is behind it. One digit after the comma means the denominator of the fraction 10, two digits after the comma means the denominator of the fraction 100, and so on.
  • A percent fraction is a fraction that has a denominator of 100, expressed in the form a%. example 50% is the same as \frac{50}{100}

Answer:

\frac{1}{2}

Step-by-step explanation:

3( \frac{6}{8}  -  \frac{1}{2} ) + 0.25 =  \frac{3 \times 2}{4 \times 2}  -  \frac{1}{2}  =  \frac{3 - 2 \times 1}{4}  =  \frac{1}{4}  + 0.25 =  \frac{50}{100}  =  \frac{1 \times 50}{2 \times 50}  =  \frac{1}{2}

Solve for y <br> 5y-x=10<br><br> Is it 2?
svet-max [94.6K]
5y-x=10
Isolate the variable
add x to both sides
5y-x+x=10+x
5y=10+x
Divide both sides by 5
5y/5=10+x/5
y=2+1/5x 
So y is equal to 2+1/5x

roll the die twice. what is the probability of rolling a 6 on the 1st roll? an odd number on the 2nd roll?
Crank
The probability of rolling a 6 on the 1st roll is \frac{1}{6}, since there is only 1 out of 6 sides of the dice that has six pips.

The probability of rolling an odd number is \frac{1}{2}, since there are 3 out of 6 sides of the dice that has an odd number of pips. \frac{3}{6} =  \frac{1}{2}

Then the probablity of both events happening one after another is \frac{1}{12}. You have to multiply both probabilities of the events: \frac{1}{6} *  \frac{1}{2} = \frac{1}{12}

A study on students drinking habits wants to determine the true average number of alcoholic drinks all UF male students have in
Butoxors [25]

Answer:

B. 97

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.95}{2} = 0.025

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.025 = 0.975, so z = 1.96

Now, find M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

How many students should be sampled to be within 1 drink of the population mean with 95% probability?

This is n when M = 1

We know from preliminary studies that the standard deviation is around 5, so \sigma = 5

M = z*\frac{\sigma}{\sqrt{n}}

1 = 1.96*\frac{5}{\sqrt{n}}

\sqrt{n} = 5*1.96

(\sqrt{n})^{2} = (5*1.96)^{2}

n = 96.04

We round up, so the correct answer is:

B. 97
