Explain how you can use reasoning to compare two fractions with the same denominator

1 answer:

7 0

When two fractions have the same denominator, you can compare which fraction is greater by just comparing the numerators.
For example, if you have 2/5 and 3/5, the denominators are the same. So you can just look at the numerators. 3 is greater than 5, so 3/5 is greater than 2/5.

The reasoning to this is that the two numbers are divided by the same number (5), so you can compare the original numbers (numerators).

Inga [223]

Answer:

Step-by-step explanation:

The sum of squares of the deviation from mean=sum(x-xbar)²=?

xbar=sumx/n

xbar=(12+6+15+9+18+12)/6=72/6=12

x x-xbar (x-xbar)²

12 12-12=0 0

6 6-12=-6 36

15 15-12=3 9

9 9-12=-3 9

18 18-12=6 36

12 12-12=0 0

sum(x-xbar)²=0+36+9+9+36+0=90

So, the sum of squares of the deviations from the mean is 90.

Use the graph for this question:

Nadya [2.5K]

You basically need to find the slope of (2,-3) and (3,-1). Where x is 2, y is -3 and were x is 3, y is -1.
Slope is y2-y1/x2-x1
2 is your slope. So, the average rate of change from x=2 and x=3 is 2.
Hope I helped!

Assume that females have pulse rates that are normally distributed with a mean of 74.0 beats per minute and a standard deviation

allsm [11]

Answer: 0.9726

Step-by-step explanation:

Given : Females have pulse rates that are normally distributed with a mean of 74.0 beats per minute and a standard deviation of 12.5 beats per minutes.

i.e. $\mu=74$ and $\sigma=12.5$

Let x is a random variable to represent the pulse rates.

Formula : $z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

For n= 16 , the probability that her pulse rate is less than 80 beats per minute will be :-

$P(x$

Hence, the required probability = 0.9726
