Answer:
Get a calculator
Step-by-step explanation:
Most of the time for simple math like multiplying 2 digits, it is easiest if you just get a calculator. It saves a lot of time.
If you can't get a calculator then i recommend memorizing some common equations.
For example 10*15= 150
so that if you get 12*15=?, you can easily just add two extra 15's to your answer of 150.
15+15 is 30, and 30+150(from 10*15)=180.
Therefore 12*15=180.
:) Hope that helped!
Answer:
The test statistics is 
Step-by-step explanation:
From the question we are told that
The data given is
330 620 1870 2410 4620 6396 7822 81028309 12882 14419 16092 18384 20916 23812 25814
The population mean is 
The sample size is n = 16
The null hypothesis is 
The alternative hypothesis is 
The sample mean is mathematically evaluated as
So
=> 
The standard deviation is mathematically represented as
So
=> 
Generally the test statistic is mathematically represented as
From the z-table the p-value is
From the values obtained we see that
so we fail to reject the null hypothesis
Which implies that the claim of the NarStor is wrong
Mrs. Clark had one hundred pencils, and wanted to divide them evenly upon the ten students in her class. How many pencils should each student have?
To solve:
Divide 100 pencils by 10 students.
Answer:
10 pencils.
Ok so substitute the values. a=3 b=2 and c=-3
-3^(2)-3(2)^(3)+(-3)^(2)+2(2)^(3)-(-3)^(2)=-9-24+9+16-9=-33+25-9=-42+25=-17
<span>From the given information cosec theta times tan theta times cos theta, writing this triginometric expression as an equation.
cosec theta x tan theta x cos theta
cosec theta = 1/sin theta
tan theta = sin theta / cos theta
Calculating the equation after substituting
(1/sin theta) x (sin theta / cos theta) x (cos theta) = 1</span>
