Dude, it's easy!
t = d/s
t = 375/500
Now do the math! Get up your lazy butt to get ur phone or a calculator! Wasting your time typing this question when you can do it yourself, the nerve of some people!
BTW why is there a chinese character in your problem? This ain't Mandarin!
You're Welcome :)
Answer:
25x³ + 13x² + 12x + 3
Step-by-step explanation:
(3x²+ 5x +6) + (25x³ + 10x² + 7x– 3)
3x²+ 5x + 6 + 25x³+ 10x² + 7x – 3
25x³ + 3x² + 10x² + 5x + 7x + 6 - 3
25x³ + 13x² + 12x + 3
Answer:
n = 195
Step-by-step explanation:
What sample size is necessary such that a 98% confidence interval for the mean, using σ = 3, has a width of pm±0.5?
We solve using Margin of error formula
= z × Standard deviation/√n
Margin of error = ± 0.5
Standard deviation = 3
n = ??
z = 2.326
Hence,
±0.5 = 2.326 × 3/√n
Cross Multiply
±0.5 × √n = 6.978
√n = 6.978/±0.5
√n = ±13.956
Square both sides
n = (±13.956)²
n = 194.769936
Approximately = 195 samples

Answer: -6(n - 3) = 18, n = 0
Step-by-step explanation:
The equation "The difference between a number and three is multiplied by negative six. The result is eighteen." can be expressed as -6(n - 3) = 18. To find n, you solve algebraically to get n = 0.
I hope this helps!
