Answer:
A.) Both lines pass through the point represented by the ordered pair
Step-by-step explanation:
Answer: 1080 degrees
Step-by-step explanation:
Since the general formular is
(n - 2 )180 = interior angle.
Where n is the number of sides the polygon has.
Octagon has 8 sides so therefore n= 8.
(8-2 ) * 180
= 6 * 180
=1080.
The total number of the interior angles measured is 1080 degrees.
Answer:
The estimate of a population proportion is approximately 541.
Step-by-step explanation:
We can solve the the problem by using the formula for minimum sample needed for interval estimate of a population proportion which is given by the formula
n = pq ((Z/2) / E)^2
As, p is not defined so we use the standard p and q which is 0.5 and 0.5.
The reason for this is we have to choose form 0.1 to 0.9 both values of p and q, we will find the maximum value of pq occurs when they both are 0.5.
Next, we will find the value of (Z/2) by looking at the Z-table, we will find that at 98% confidence (Z/2) = 2.326. Now we start substituting the values in the above formula
n = (0.5)×(0.5) × (2.326/0.05)^2
n = 541.027
n ≅ 541.
Less than is subtraction so your answer to "six less than a number is 14" would be
n-6=14
Answer:
D)22.5cm
CB/BA=HG/13.5
CB=15cm,BA=9cm,HG=x and GF=13.5
15/9=x/13.5(divided by 13.5both sides)
x=22.5cm
