Answer:
it's a quadratic formula
Step-by-step explanation:
in the formula, substitute the value of <u>a as 1, b as 2 and c as -8</u>
then, you will get ur answer
To find 20% of 119.50 you multiply 119.50 by 20% in decimal form
Then you subtract the discount (d) from the total to get your new price (n)
119.5*.2=d
23.9=d
119.5-d=n
119.5-23.9=95.6
So the new price is <u><em>$95.60</em></u>
Answer:
<h3>The option D) 1.50 is correct</h3><h3>That is the standard error of the sample mean is 1.50</h3>
Step-by-step explanation:
Given that a population that consists of 500 observations has a mean of 40 and a standard deviation of 15.
A sample size is 100 taken at random from the given population.
<h3>To find the standard error of the sample mean :</h3>
From the given Mean=40 and
For N=100
<h3>The formula for standard error is
</h3>
Substitute the values in the above formula we get
∴
<h3>∴ The standard error of the sample mean is 1.50</h3><h3>Hence the option D) 1.50 is correct</h3>
Answer:
{35} square units
Step-by-step explanation:
To find the area of a parallelogram, multiply the base by the height.
Formula :- A = B × H
B→ Base
H→ height
Area of the parallelogram = Base × Height
→ Area= 5×7
→ 35
hope it helps...
have a great day!!
