Take the square root. The opposite of squaring something is taking the root :)
√x^2 = √26
x = √26
x = 5.099...

Answer:
The type of food they are feeding the dog.
Step-by-step explanation:
The independent variable is the test variable of the experiment. Therefore, you can see that Pablo and Johanna both use different types of food to feed their dogs, to see which one grows faster. The growing faster is the dependent variable because how fast the dogs grow is what is being measured.
Answer:
768
Step-by-step explanation:
Given that:
Error margin (E) = 5% = 0.05
Confidence level = 95%
Proportion p = 0.5 (since no prior value is given) ; also n1 = n2 = sample size
n = (Z / E)^2 * (1 - p)
1 - p = 1 - 0.5 = 0.5
Zscore at 95% confidence = 1.96
n = (1.96 / 0.05)^2 * 0.5
n = 39.2^2 * 0.5
n = 1536.64 * 0.5
n = 768.32
Hence, sample size = 768 SAMPLES
