Step-by-step explanation:
The field of statistics is the science of learning from data. Statistical knowledge helps you use the proper methods to collect the data, employ the correct analyses, and effectively present the results. Statistics is a crucial process behind how we make discoveries in science, make decisions based on data, and make predictions. Statistics allows you to understand a subject much more deeply.
Answer:
54 degrees
Step-by-step explanation:
Every side of a regular pentagon is same.
So we have an isosceles triangle. The correspond angle of y, must equal to y (degree) too.
Also, every inner angle of a regular pentagon is 360/5=72. So we can calculate angle y, by the equation y+y+72=180.
y=54
The answer is c. 6/10 because it is equivalent to 3/5 when you simplify. Everything else is 2/5.
Answer:
B: 15 hours
Step-by-step explanation:
Since Dara spends 2 hours reading 72 pages, we can conclude that she spends 1 hour reading 36 pages.
Since we are finding how long it would take for her to read 540 pages, we would divide 540 by 36, which is 15.
Length = 13 = (x + 3)
Width = 14 = (x + 4)
x2 + 7x + 12 = area of the rectangle
can be factored into
(x + 3)(x + 4)
Let L = one of the factors (x + 3)
Let W = the other factor (x + 4)
If x = 10 then
(10 + 3) = 13 = L
(10 + 4) = 14 = W
Checking this can be checked a couple of ways
Plug x = 10 into the original equation
x2 + 7x + 12
102 + 7(10) 12 = 100 + 70 + 12 = 182 = Area
Multiplty the factors
L x W = 13 x 14 = 182 = Area
