Answer:
36 grams
Step-by-step explanation:
Convert 15% to decimal form to get 0.15
0.15x240=36
Answer:
D
Step-by-step explanation:
To find out the price lets divide
11.16/ 4 = 2.79 per pack
17.94/6= 2.99 per pack
24.96/8= 3.12 per pack
39.75/15= 2.65 per pack
2.65 is the cheapest out of all of the choices
I think it’s true because 3 and 6 are the same degree angle but I just did this lesson on acellus summer schools hitting hard
Answer:
1) The correct z* to to construct a 92% confidence interval is 1.75
2) these results are not good evidence that the new curriculum has improved Math SAT scores.
3) the results are not statistically significant at level α = 0.05, but they are practically significant.
Step-by-step explanation:
1) z-score for 92% confidence level is ≈ 1.75
2) P-value for testing whether the mean score in senator's state is more than the national average of 480 is less than 0.0001 means that
the probability that the sample is drawn from the population where senator's state is more than the national average of 480 is <0.0001.
Thus we have to reject this hypothesis since the probability is too small.
3) if we calculate the statistic of the sample we get (560-480)/100=0.8 where
- 560 is the mean score of trained 4 students
- 480 is the mean math sat score of this year
- 100 is the standard deviation of the test.
Since t-critical at 0.05 significance for 3 degrees of freedom ≈ 2.35 is bigger than 0.8, the result is not significant statistically.
But 80 points higher than the national average is a practically significant result since its <em>effect size</em> is large.
Answer:
Correct choice is B
Step-by-step explanation:
Let x% be your final test score, then the average of all test scores is
Since you must have an average between 80% and 89%, then
X is measured in percent, then the greatest value of x can be 100%. You get that
