Answer:
P(x>278) is 0.16
Step-by-step explanation:
We are given that a normal distribution has a mean of 266 and a standard deviation of 12.
Mean = 
Standard deviation =
We are supposed to find P(x > 278)
So, Formula : 
Z=1
Refer the z table for p value
p value = 0.8413
P(x<278) is 0.84
P(x>278)=1-P(x<278)=1-0.84=0.16
Option A is true
Hence P(x>278) is 0.16
Answer:
Step-by-step explanation:
1/4 ( x+10) = x -4
one fourth the sum of x and 10 is identical to x minus 4

the first one would be 65 and 23/1000, while the other one is 65 and 23/100
Answer:
d)1.08421 x 10^25 Kg
Step-by-step explanation:
The combined weight of these two bodies would be the addition of the masses of the two bodies.
Given that Earth weight is 5.9736 x 10^24 Kg and Venus is 4.8685 x 10^24 Kg,
The combined weight of Earth and Venus
= 5.9736 x 10^24 Kg + 4.8685 x 10^24 Kg
=10^24(5.9736 + 4.8685)
= 10.8421 × 10^24 Kg
In standard form,
= 1.08421 × 10^25 Kg
