Answer:
Step-by-step explanation:
Since, angle 1 is an exterior angle of ΔABE,
m∠1 > m∠3 and m∠4
Since, angle 1 is an exterior angle of ΔABD,
m∠1 > m∠5
Since, angle 1 is an exterior angle of ΔABC,
m∠1 > m∠7 and m∠8
Therefore, ∠1 is greater than ∠3, ∠5, ∠7 and ∠8.
Answer:
<h3>The standard error of the mean is <u>15</u></h3>Step-by-step explanation:
Given that a simple random sample of 64 observations was taken from a large population.
Hence it can be written as n=64
The population standard deviation is 120.
It can be written as
The sample mean was determined to be 320.
It can be written as
The formula for the standard error of the mean is given by
Now substitute the values in the formula we get
The club needs to make and sell 29 t-shirts in order to profit at least 150.
<em><u>Explanation</u></em>
Suppose , the number of t-shirts the club needs to make and sell is
Selling price of each t-shirt is 15, so the total selling price of t-shirts
It costs 20 plus 9 per t-shirt to make the t-shirts. So, the total making cost of t-shirts
Now for getting profit at least 150 , the equation will be.....
It means the value of x should be at least 28.333...
<em>As here x is the number of t-shirts and it can't be in decimal , so </em><em>the minimum value of x will be 29.</em>
