Answer:
The mean is
The standard deviation
Step-by-step explanation:
From the question we are told that
The data given is
Temperature Lower Limit Upper Limit Days
50-59 50 59 2
60-69 60 69 313
70-79 70 79 1419
80-89 80 89 1503
90-99 90 99 319
100-109 100 109 9
Generally the average of each limit is evaluated as
Temperature Lower Limit Upper Limit Average Days
50-59 50 59 ( 50 + 59 )/2 =54.5 2
60-69 60 69 (60+69)/2 = 64.5 313
70-79 70 79 (70+79)/2 =74.5 1419
80-89 80 89 (80+89)/2 =84.5 1503
90-99 90 99 (90+99)/2 = 94.5 319
100-109 100 109 (100+109)/2 = 104.5 9
Generally the mean is evaluated as
=>
Generally the standard deviation is evaluated as
N is 3 bc #of terms minus 1
Exponents go from 3>2>x>none
Can be factored using binomial theorem
8 -<u> 8</u>, 16, 24, 32, 40, 48
4 - 4, <u>8</u>, 12, 16,
So the LCM of 8 and 4 are C) 8
8 - 8, 16, <u>24</u>, 32, 40, 48
6 - 6, 12, 18,<u> 24</u>, 30
So the LCM of 8 and 6 are A) 24
8 - 8, 16, 24, 32, <u>40</u>, 48
10 - 10, 20, 30, <u>40</u>, 50
The LCM of 8 and 10 are B) 40
Hope this Helps!!
7 x 10^-5
0.00001 is 1 x 10^-5 so multiply that by 7
x=8
The ratio of a side of PQRS to the corresponding side in TUVW. is 6:4=3:2.
The ratio of RS:VW=3:2. RS=12, and VW=x. 12:x=3:2. 3 multiplied by 4 is 12, so 2 multiplied by 4 is x. So, the makes x=8.
