the area of the first shape is 4 times 12 which is 48 and the area of the second shape is 2 times 10 which is 20
48+20= 68 mi2
Answer
C. 49, 17, 4, 18
Step by step explanation
Here mean of all the data set is 88
To find the most spread of data, we need to find the range.
range of set A = The highest value - the lowest value = 36-6 = 30
Range of set B = 30-15 = 15
Range of set C = 49-4 = 45
Range of set D = 30-14= 16
Here the highest range is in Set C.
Therefore, answer is C. 49, 17, 4, 18
Answer:
The value of Cos(01) is 0.866 or √3/2
Step-by-step explanation:
In this question, we are asked to calculate the value of cos (01) given the value of sin(01)
Now, given the value of sin (01), we can calculate the value of cos (01).
To get the value of 01, we simply find the value of the arc sin 01
Mathematically since sin (01) = 1/2
(01) = arc sin (1/2)
(01) = 30 degrees
Now since 01 = 30 degrees
cos 01 = Cos (30) = 0.8666 or simply √3/2
First divide by 4 to get x^2=9. Then take the square root of both sides. x=3 and x = -3.
Answer:
0.625
Step-by-step explanation:
Given :
Ambell company uses or procures batteries from two manufacturers.
The life of a battery in critical tool is at = 32 hours
Ambell uses 70% of its batteries from manufacturer 1 and out of that 90% batteries lasts for about 40 hours.
Similarly, 75% of the batteries procured from the manufacturer 2 lasts for about 40 hours.
Therefore, the probability that a battery is form manufacturer 1 is :
= 0.625
