<h3>
Answer: 72.54</h3>
====================================================
Explanation:
We set up a cosine ratio, since we want to connect the adjacent and hypotenuse. Then we'll use the inverse cosine, which is also known as arccosine, to isolate the angle value.
This is what your steps could look like:
cos(angle) = adjacent/hypotenuse
cos(L) = LM/LN
cos(L) = 18/60
cos(L) = 0.3
L = arccos(0.3)
L = 72.542396876278 which is approximate
L = 72.54 degrees approximately
Make sure your calculator is in degree mode.
Answer:
44 units
Step-by-step explanation:
We know that in a parallelogram opposite sides are equal.
Therefore AB=CD and AD=BC
Consider AB=CD,
⇒4y-2=2y+6
⇒2y=8
⇒y=4
Now consider AD=BC,
⇒3x-1=2x+2
⇒x=3
now substituting values of x and y in the expressions of sides,
we get AB=CD=14 units and AD=BC=8 units
Therefore perimeter of parallelogram is 2*(AB+BC)=2*(14+8)=<u>44 units</u>
2x+7=16
Katherine divided wrong. She shouldn't have divided by 2 because 7 isn't a multiple of 2; x+7≠16:2.
She should have proceed like that:
2x+7=16|-7
2x=16-7
2x=9
x=9:2
x=4,5
Answer with Step-by-step explanation:
Since we have given that
Average per week in sales = $8000
Steve hopes that the results of a trial selling period will enable him to conclude that the compensation plan increase the average sales per salesperson
So, the appropriate null and alternate hypothesis would be
b. What is the Type I error in this situation? What are the consequences of making this error?
Type 1 error are those errors in which null hypothesis are supposed to be rejected, but it does not get rejected.
It means sales per week is greater than $8000 but in actual it is not.
c. What is the Type II error in this situation? What are the consequences of making this error?
Type 2 are error are those errors in which null hypothesis are supposed to be accepted but it get rejected.
It means average sales per week is actually $8000 but it is calculated that average sales is less than $8000.
When u have an exponential functions with a number between 0 and 1, the curve is decreasing. it would approach 0, but the -2 at the end which shift the whole thing down 2, so it would approach -2 instead
answer: c
