Answer:
61.25
Step-by-step explanation:
2 1/2 is 2.5 in decimal.
24.5*2.5
Multiplying 24.5 by 2.5 gives 61.25
Step-by-step explanation:
The statement in the above question is True.
Sum of three prime numbers (other than two) is always odd.
Going by Christian Goldbach number theory ,
- Goldbach stated that every odd whole number greater than 5 can be written as sum of three prime numbers .
Lets take an example,
- 3 + 3 + 5 = 11
- 3 + 5 + 5 = 13
- 5 + 5 + 7 = 17
Later on in 2013 the Mathematician <u>Harald Helfgott</u> proved this theory true for all odd numbers greater than five.
The formula is
I=prt
I interest earned?
P principle 1295
R interest rate 0.07
T time 180/365
I=1,295×0.07×(180÷365)
I=44.70
Answer:
<h2>y = 3</h2>
Step-by-step explanation:
If a line has slope 0, then it's a horizontal line.
A horizontal line has an equation:
<h2>y = a</h2>
where a is any real number.
The line passes through point (-12, 3) → x = -12, y = 3.
Therefore the equation is
<h2>y = 3</h2>
Answer:
1,082
Step-by-step explanation:
The sample size n in Simple Random Sampling is given by

where
z = 1.645 is the critical value for a 90% confidence level (*)
s = 2 is the estimated population standard deviation
e = 0.1 mm points is the margin of error
so

rounded up to the nearest integer.
So the manufacturer should test 1,083 parts.

(*)This is a point z such that the area under the Normal curve N(0,1) outside the interval [-z, z] equals 10% = 0.1
It can be obtained in Excel with
NORMINV(1-0.05,0,1)
and in OpenOffice Calc with
NORMINV(1-0.05;0;1)
