|-a^2|= |-5^2|= |25|= 25

You basically substitute the values for the letters. -5 x -5 =25 then you find the absolute value which is 25. 

****Is this the whole problem or only half because you gave the values for b and c but there was only a.

Is 0.99 an repeating number
Black_prince [1.1K]

Answer:

No

Step-by-step explanation:

0.99 is not a repeating decimal because it terminates, meaning that it "ends". We know this because there are no more digits after 9 and there is no "..." at the end of the decimal.

If the null hypothesis of an experiment is “The true mean weight of the piglets is at least 39lbs” what is the alternate hypothe
AlexFokin [52]

Answer:

“The true mean weight of the piglets is at most 39lbs”would be the alternate hypothesis.

Step-by-step explanation:

Given that  the null hypothesis of an experiment is “The true mean weight of the piglets is at least 39lbs”

We have to find the alternate hypothesis.

In hypothesis testing, alternate is the opposite of null hypothesis.  If null hypothesis supports one statement alternate hypothesis opposes it.  In other words, alternate hypothesis would be the negative of the claim of null hypothesis.

Here the null hypothesis of an experiment is “The true mean weight of the piglets is at least 39lbs”

i.e H0: x bar\geq 39 lbs

So alternate hypothesis

Ha:  x bar\leq 39 lbs

Hello please help me! There are 3 questions, I will give brainliest!
Shalnov [3]

Answer:

1) There are 13 students in Jerry's study.

2) There are 39 students in Kathy's study.

3) Jerry's study is more trustworthy!

Step-by-step explanation:

1) Jerry's study is the one with the dot plot.

Now, the number of students is calculated by adding the total number of dots in the plot.

We have a total of 13 dots.

Thus, there are 13 students in Jerry's study.

2) Kathy's study is the one with the histogram.

The total number of students is gotten by adding the corresponding number of students on the y-axis for each range of distance on the x-axis.

Total number of students = 9 + 11 + 7 + 12 = 39 students

3) Jerry's study where he used a dot plot is likely to be more trustworthy because it gives exact values of the number of students for each distance represented whereas, Kathy's study where she used a histogram doesn't give exact values but just gives a range of distances for a particular number of people.
