250 - 5(x) = 50
250 (-250) - 5x = 50 (-250)
-5x = -200
-5x/-5 = -200/-5
x = 40
hope this helps

<em>Answer:</em>
<em>Can be found below</em>
<em>Step-by-step explanation:</em>
<em>Part A:</em>
<em>So we know that the bacteria doubles every (30) minutes.</em>
<em>2000 times 2 equals 4000 (30 minutes)</em>
<em>4000 times 2 equals 8000 (1 hour)</em>
<em>Answer for Part A:</em>
<em>8000 bacteria</em>
<em>Part B:</em>
<em>Now we do this function 2000(2)^14 (30 minutes long)</em>
<em>Answer to Part B: </em>
<em>I believe the answer is 32,768,000 (Please correct me if I'm wrong) </em>
<em>Hope I could help!! Have a great day/night!</em>

Answer:
B is True
A, C. D are false
Step-by-step explanation:
Given :
Sample size, n = 120
Mean diameter, m = 10
Standard deviation, s = 0.24
Confidence level, Zcritical ; Z0.05/2 = Z0.025 = 1.96
The confidence interval represents how the true mean value compares to a set of values around the mean computed from a set of sample drawn from the population.
The population here is N = 10000
To obtain
Confidence interval (C. I) :
Mean ± margin of error
Margin of Error = Zcritical * s/sqrt(n)
Margin of Error = 1.96 * 0.24/sqrt(120)
Confidence interval for the 10,000 ball bearing :
10 ± 1.96 * (0.24) / sqrt(120)
Hence. The confidence interval defined as :
10 ± 1.96 * (0.24) / sqrt(120) is the 95% confidence interval for the mean diameter of the 10,000 bearings in the box.
Answer:
6(2x-3)= -9 given
12x-18= -9 distribute
12x-18+18= -9+18 addition
12x= 9 division
x= 3/4 solution
Step-by-step explanation:
The coordinates of "A" would most likely replace those of "B" or be very close. Brainliest is always appreciated, feel free to ask another question, and Have a nice day!
