Answer:
6 years
Step-by-step explanation:
Given
Required
When will it get to 4000
This question illustrates a geometric progression and will be solved using:
In this case;
So, we're to solve for n
Divide through by 150
Take Log of both sides
Apply law of logarithm
Take Log values
Make n - 1 the subject
Add 2 to both sides
(Approximated)
<em>Hence, it'll take 6 years</em>
7 X 4 = 28 if it’s hard for you just add 7, 4 times
Answer:
No, the conditions for normality have not been met because the sample size for the quarters is not large enough and no information is given about the distributions of the populations.
Step-by-step explanation:
"The Kolmogorov-Smirnov test (K-S) and Shapiro-Wilk (S-W) test are designed to test normality by comparing your data to a normal distribution with the same mean and standard deviation of your sample. If the test is NOT significant, then the data are normal, so any value above .05 indicates normality"
The value of x+y+z = 93
<u>Explanation:</u>
<u></u>
angle 1 = 18x
angle 2 = x+y
angle 3 = 30z
In rhombus, the diagonals intersect at 90°
Therefore,
angle 1 : 18x = 90
x = 90/18 = 5
angle 2: x+y = 90
5+y = 90
y = 85
angle 3: 30z = 90
z = 90/30 = 3
Value of x+y+z = 5+85+3 = 93
Thus, the value of x+y+z = 93
