Answer:
-232
Step-by-step explanation:
the salt flats have an elevation of 50 feet greater than -282, so add 50 to -282 and you get -232
Answer: -1/5
Step-by-step explanation:
14/20 - 81/90=
7/10-9/10= ==> 10 is the GCF of 20 and 90
(7-9)/10=
-2/10=-1/5
I’m not sure but I got 8 ^-5
Answer:
Mean = 35
Variance = 291.7
Step-by-step explanation:
Data provided in the question:
X : 1, 2, 3, 4, 5, 6
All the data are independent
Thus,
The mean for this case will be given as:
Mean, E[X] = 
or
E[X] = 
or
E[X] = 3.5
For 10 days, Mean = 3.5 × 10 = 35
And,
variance = E[X²] - ( E[X] )²
Now, for this case of independent value,
E[X²] = 
or
E[X²] = 
or
E[X²] = 
or
E[X²] = 15.167
Therefore,
variance = E[X²] - ( E[X] )²
or
variance = 15.167 - 3.5²
or
Variance = 2.917
For 10 days = Variance × Days²
= 2.917 × 10²
= 291.7
Answer:
Hey,

Step-by-step explanation:
=(2x+5)(3x+2)
=(2x)(3x)+(2x)(2)+(5)(3x)+(5)(2)
=6x^2+4x+15x+10
=6x^2+19x+10(ANS)
