Answer: x = 11
Step-by-step explanation:
same as the last question, set them as equal and solve. here's my work:
<em>5x - 1 = 4x + 10</em>
<em>5x - 1 (+ 1) = 4x + 10 (+ 1)</em>
<em>5x = 4x + 11</em>
<em>5x (- 4x) = 4x (- 4x) + 11</em>
x = 11
Answer: ± 1.96
Step-by-step explanation:
Given the following :
Mean (m) time spent = 11.85
Standard deviation = 4 minutes
Since the population of site visits is Normally distributed, Hence, the test statistic will follow a normal distribution :
The test the hypothesis that mean time has changed at 0.05 confidence interval
Normal distributions have a mean value of 0 and standard deviation of 1
Using a two tailed test At 0.05 confidence interval ;
Using the critical value calculator, which in general under normal distributions :
0.05% confidence interval for a two tailed test is
± 1.96
There is no question. I’m sorry :(. Can you mark me as brainliest so I can help more people !!?
Answer:
The expression is equal to 8
Step-by-step explanation:
This is the question in proper
6t−20−32u
When u= 1/4 t= 6
We were given this, 6t−20−32u then we were given the value of u= 1/4 and that of t= 6.
All we need here is to substitute u= 1/4 t= 6 into 6t−20−32u then evaluate it as follows
6(6)-20-32(1/4)
6×6=36
32×(1/4)=8
Then merge it together and calculate it we have
=36-20-8=8
