Multiply2 * x/15 to 2x/15
multiply both sides by 30 which is the LCM of 10, 5, 3, and 15
expand it
simplify 18 - 15x - 12x - 6 + 10x to 12 - 17x
add 17x to both sides
add 4x + 17x to = 21x
divide both sides by 21
simplify 12/21 to 4/7
now simplify
Answer: x = 4/7.

Answer:
130.4 pounds
Step-by-step explanation:
The digital scale is measuring weight to the nearest 0.2 pounds, so basically the digital scale would show you the weight of an object that is a multiple of 0.2.
Talking about precision, precision tells us how accurate is the measured value or how close is the measured value to the actual value.
Here, scale is measuring to the nearest 0.2 pounds, so out of the given values the measurement that shows an appropriate level of precision for the scale is 130.4 pounds.
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
