Area = length x width
the "big" rectangle: length = 15, width = 14
the blue rectangle is: length = 15 - 4, width = 14 - 6
Area of blue rectangle = (15 - 4)(14 - 6)
Answer: D
The opposite angles equal each other, so X and Z are equal
using that we solve for x by setting them equal:
6x-60 = 2x+68
subtract 2x from each side:
4x -60 = 68
add 60 to each side:
4x = 128
divide both sides by 4
x = 128/4
x = 32
now we know x so we can solve everything else by replacing x with 32
WY = 3x+5 = 3(32)+5 = 96+5 = 101
angle Z = 2x+68 = 2(32)+68 = 64+132
the answer is C
The best estimate of the population means is always the sample mean. We have the sample values, using them we can find the sample mean.
The sum of the sampled rates = 248
Sample Size = 10
Mean value of the sample = Sum of Sample Rate/Sample Size
So,
Mean of the sample = 248/10 = 24.8
Therefore, we can say that the best estimate for the population mean is 24.8
Answer: the statement made by Tim Cook is TRUE
Step-by-step explanation:
Given that;
in 2007 cost of 1st gen iphone = $499 (base year price)
cost of iphone today = $999 (current year price)
Using the Consumer Price Index
the Consumer Price Index = (cost pf product in current years/cost of product base year) × 100
we substitute
CPI = (999/499) × 100
CPI = 200.2004
so the CPI is 100.2004% higher in the current year than in the base year
Checking the inflation rate
IR = (( CPI this year- CPI last year)/CPI last year) × 100
CPI last year (base year) = 100
CPI current year is = 100.2004
so
IR = (( 100.2004 - 100)/100) × 100
IR = 0.002004 × 100
IR = 0.2004%
THEREFORE the statement made by Tim Cook is TRUE
