We formulate the null and alternative hypothesis here to state that battery life of the laptop lasts at least 12 hours(more than but not less, null hypothesis) or that it lasts less than 12 hours(alternative hypothesis).
The null hypothesis is the one being tested to know whether we would reject it or not in which case we choose the alternative hypothesis. To test the hypotheses, we do a t test using a significance level of say 0.05(95% confidence interval) and find our p value in order to compare and decide if the null hypothesis would be rejected or not based on statistical significance.
Here, angle 1 and angle 2 are congruent (as they are equal in magnitude ) because they are a pair of corresponding angles (as they are at same location on transversal line)
In short, Your Answer would be Option B
Hope this helps!
Answer:
B
Step-by-step explanation:
Remember that slope=rise/run. You can find the right graph with the slope of 2/3 very easily by counting, upward 2 and rightward 3.
The answer is 10/5 which equals 2
Answer:
2.25 Cups.
Step-by-step explanation:
We know that we can change the 1 1/2 to 3/2.
Next, we want the LCM, or Lowest Common Denominator.
Denominator is the bottom part of the fraction.
The Lowest Common Denominator for 2/3 and 3/2 is 6.
So we need to change the denominators to 6.
To do that, we would multiply 2/3 by 2, and multiply 3/2 by 3.
Then we get 4/6, and 9/6.
Divide 9/6 by 4/6 and you will get your answer.
Which is 2.25.
Or.. 2 1/4.
