Answer:
The possible values of x are ±8 sqrt(2)
Step-by-step explanation:
To find the value of x, we find the geometric mean
sqrt(32*4 )= sqrt(128) = ±8 sqrt(2)
The possible values of x are ±8 sqrt(2)
Answer:157/10
Step-by-step explanation:
Make 15 into an improper fraction (every number is a fraction over 1) so multiply the numerator(15) and the denominator(1) by 10 to get 150/10 then add 150/10 to 7/10 to get 157/10
Answer: Approximately 3.15%
Explanation:
The true finishing time is 22.2 seconds. The prediction furthest from this is 22.9 seconds. This is a difference of 22.9-22.2 = 0.7 seconds. Divide this over the true time value to get (0.7)/(22.2) = 0.03153 which is approximate.
Move the decimal point to the right 2 spots to get to 3.153%; round this value however you need to.
