Answer:
The sample size is
Step-by-step explanation:
From the question we are told that
The standard deviation is
The precision is
The confidence level is 98%
Generally the sample size is mathematically represented as
Where is the level of significance which is mathematically evaluated as
%
and is the critical value of which is obtained from the normal distribution table as 2.326
substituting values

Step-by-step explanation:
<u>Step 1: Define</u>
8a - 15 - 6a + 3a = 85
<u>Step 2: Solve for </u><em><u>a</u></em>
- Combine like terms: 5a - 15 = 85
- Isolate <em>a</em> term: 5a = 100
- Isolate <em>a</em>: a = 20
Angle a is 80, angle d is 100, angle c is 100
<em>The answer is "y > x-2 and y < x + 1"
</em>
<em>
</em>
<em>Step-by-step explanation:
</em>
<em>
</em>
<em>In the given question the last choice, that is "y > x-2 and y < x + 1" which can be defined in the following diagram.</em>
Well if its 95/100 then you would move the decimal over twice because it's 2 0's and the same thing with 10 move the decimal over 1 because it's 1 zero and if it's not 10 or 100 then you would divide the denominator into the numerator and then when you do that move the decimal over from the front to the back so that's twice then put your percent sign at the end
