Answer:
12 11/35
Step-by-step explanation:
Given Data
First term= 15 3/5
To simple fracrion= 78/5
Second term= 3 2/7
To simple fracrion= 23/7
Hence the operation goes thus
= 78/5- 23/7
LCM = 35
=546-115/35
=431/35
=12 11/35
Answer:
√17
Step-by-step explanation:
An irrational number is a number that cannot be expressed as a ratio of two integers. Or in other words, an irrational number can't be expressed as a fraction. You really cant divide one integer by another integer to get √17, so that makes it an irrational number.
I’m not sure if this is correct but i got, 7c^2c^2 + 49c^4 + 35bc^2
Answer:
The 99% confidence interval of the standard deviation of the pulse rates of men is
Step-by-step explanation:
From the question we are told that
The sample size is n = 40
The mean is
The standard deviation is
Generally the degree of freedom is mathematically represented as
=>
=>
From the question we are told the confidence level is 99% , hence the level of significance is
=>
Generally from the chi distribution table the critical value of at a degree of freedom of is
Generally from the chi distribution table the critical value of at a degree of freedom of is
Generally the 99% confidence interval of the standard deviation of the pulse rates of men is mathematically represented as
=>
=>
The simplest form is 3/8. this because 4 divides both sides
