hi
here is the method :
you take Value 1 and Value 2
And you do : ( Value 2 - Value 1) / (Value 1 ) * 100
Here we have : Value 1 = 352 000
Value 2 = 337 920
So now we apply :
( 337 920 - 352 000 ) / ( 352 000) * 100 = -4
Population decreased by by 4 %
You can also make :
352 000 * X = 337 920
X = 337 920 / 352 000
X = 0.96
if the multiplier is 0.96 , it's mean that we lost 1 -0.96 = 0.04
which mean - 4%
True answers for data in the plot are
The center is 13
The center is not 14
The Peak is 14.
It has three clusters
It is not symmetric to left or right it is bi-modal.
It is has a range from 10 to 15 most number of data points are 13 to 15.
Total number times Shelly waited is 16 times.
Step-by-step explanation:
- While taking cumulative frequency 56.75 percentage comes in 13%.
- It is the center point of the data.
- The 14 is not the center as it shows 93rd percent.
- It has three clusters 0-2 has one cluster,2-4 has 2nd cluster,5-8 third.
- It is not skewed on the left is has bi modal frequency has two heights.
- The person indeed waited for 16 times adding total dots.
- There was a zero 12 which created bi-modal distribution
Answer:
Length = 15
Width = 6
Area = 90
Step-by-step explanation:
Area of the rectangle = 
Lets factorise the polynomial


We know that Area = Length × Width
Let the length be (x + 3) & width be (x - 6)
Its given in the question that x = 12. So putting the value of x gives ,
Length = 
Width = 
Area = Length × Width = 15 × 6 = 90
Answer:

Step-by-step explanation:
Given that:

for 
That means, angle
is in the 3rd quadrant.
To find:
Value of cot(t)
Solution:
First of all, let us recall what trigonometric ratios are positive and what trigonometric ratios are negative in 3rd quadrant.
In 3rd quadrant, tangent and cotangent are positive.
All other trigonometric ratios are negative.
Let us have a look at the following identity:

here, 
So, 

But, angle
is in 3rd quadrant, so value of

Let x be the number of days.
Daily pass:
65x + 30x
95x
Season pass:
400 + 30x
95x > 400 + 30x
65x > 400
x > 6.15
The number of days can't be 6.15, so you must round. You can't go down because then the price will be more expensive, so you have to round up.
It would take 7 days until the season pass is less expensive than the daily pass.
----------------------
You can check this by plugging in the x.
95x > 400 + 30x
95(7) > 400 + 30(7)
665 > 400 + 210
665 > 600
The daily pass is more expensive than the season pass.
