That's the logarithmic form. Do you need with solving the equation too?
$54 (if 10 for each of the 3 students and 4 dollars each of the 6 students)
$14 if not
If you would like to know about how long was the rope before Chris cut it and you would like to round each length to the nearest tenth to estimate the total length of the original piece of rope, you can calculate this using the following steps:
11.36 meters = 11.4 meters
13.46 meters = 13.5 meters
11.4 + 13.5 = 24.9 meters
Result: The rope was 24.9 meters long (before Chris cut it) - rounded to the nearest tenth.
Answer: D. between 4.79 and 4.8
Step-by-step explanation:
The square root of 23 (√23) is 4.79583152331. We can obviously eliminate A and B. C and D is left. C is wrong because if we approximate the square root of 23, which is 4.79583152331, we get 4.79. 4.79 > 4.78, so it can't be C. Hope this helps :)
Answer:
a level of significance of 0.01 = 1%
Step-by-step explanation:
given
Z = 0.0001
mean μ=0.21 g/mi
variate x= 0.21 + 0.03
standard deviation σ= 0.05 g/mi.
N = sample population 20 cars
z = (x −μ
)/[σ
/√N ]
Z =
Z = 0.03/ (0.05/√20) = 0.03/0.0111
Z = 2.63 +- 0.0001
Z= 2.6301 or 2.6299
checking the level of significance table from a statistical book gives
a level of significance of 0.01 = 1%
therefore the null hypothesis is accepted.
