How to simplify fractions

Mathematics
2 answers:
REY [17]3 years ago

\frac{1}{2}+\frac{1}{4}      You have to make the denominators(bottom of the fraction) the same in order to combine the fractions.


To make the denominator of \frac{1}{2} the same as \frac{1}{4}, you multiply the top and bottom of the fraction by 2 (because they both have a common multiple of 4)

\frac{1*2}{2*2}=\frac{2}{4}


So:

\frac{2}{4} +\frac{1}{4} =\frac{3}{4}

Find the critical value necessary to form a confidence interval at the level of confidence shown below.
Rzqust [24]

Answer:

the critical value for 0.87 level of confidence is 1.51

Step-by-step explanation:

Given the data in the question;

level of confidence = 0.87

now,

1 - c = 0.87

c = 1 - 0.87

c = 0.13

c/2 = 0.13/2 = 0.065

now

1 - c/2  = 1 - 0.065 = 0.935

so our level of significance ∝ = 0.935

Now, the critical value will be;

Z_{0.935 is obtained as follows;

P( Z < z ) = 0.935

so we find the value from ( standard normal distribution table )

P( Z < 1.51 ) = 0.935

Therefore, the critical value for 0.87 level of confidence is 1.51

<h3>What is a bar chart?</h3>

It is defined as the visual way to show the data a systematically with rectangle box on the x-axis and y-axis. The height and vertical lines show the proportional data.

Thus, the high-tech sector employees were less likely to lose their jobs option fourth is correct.

Which numbers have a digit in the ones place that is 1/10 the value of the digit in the tens place
liq [111]

Answer:

4,099  and 5,011

Step-by-step explanation:

This problem can be solved by taking options one by one.

Option (1) : 4,099  

Digit in ones place = 9

The value of the digit in tens place = 90

\dfrac{9}{90}=\dfrac{1}{10}. It is correct.

Option (2) : 4,110

Digit in one places = 0

The value of the digit in tens place = 10

It is incorrect.

Option (3) : 5,909

Digit in one places = 9

The value of the digit in tens place = 0

It is again incorrect.

Option (4) : 5,011

Digit in one places = 1

The value of the digit in tens place = 10

\dfrac{1}{10}. It is correct.

Hence, in option (a) and (d), the he ones place is 1/10 the value of the digit in the tens place.
