Answer:
+2.718
Step-by-step explanation:
from the question,
the sample size is 12
therefore the degree of freedom,
df = 12 - 1
= 11
alpha = 1 - 0.98
= 0.02
this is because the confidence level is 98%
under the t distribution table, a degree of freedom of 11 and 0.02 alpha level = <em>2.718</em>
<em>the</em><em> </em><em>crit</em><em>ical</em><em> </em><em>valu</em><em>e</em><em> </em><em>t</em><em>*</em><em> </em><em>=</em><em> </em><em>2</em><em>.</em><em>7</em><em>1</em><em>8</em>

Answer:
angle BEF = 100 degrees
Step-by-step explanation:
For a regular 9-sided polygon (nonagon),
each exterior angle = 360/9=40 degrees
each interior angle = 180-40 = 140 degrees.
Referring to diagram, in the trapezoid (trapezium) BCDE, the base angles are 180-140 = 40 degrees.
Therefore angle DEB = 40 degrees
that leaves BEF = 140-40 = 100 degrees
Answer:P(x<10) =0
Step-by-step explanation:
M =1/μ
M= 1/15 =0.066667
X- Exp (0.066667)
Where: X is the random variable for number of days
P (X<x) = 1 - e^-mx
P(X - x) = 1 - e^-0.06666 x10
P(x<10) = 0
Answer:
the present value is 3,162 euros
Step-by-step explanation:
The computation of the present value is shown below:
As we know that
Future value = Present value × (1 + rate of interest)^number of years
3,200 euros = Present value × (1 + 0.012)^1
3,200 euros = Present value × 1.012^1
Present value is
= 3,200 euros ÷ 1.012
= 3,162 euros
Hence, the present value is 3,162 euros
