Answer:
9/14
Step-by-step explanation:
You multiply the two fractions. So 5/7*9/10, you just multiply across. This would give you 45/70. Then, after simplifying, this fraction is 9/14. So, Sean ran 9/14 of a mile on Sunday. Hope this helps, Sorry if im wrong!!

Answer:
B. It is equivalent to 20/100
C. It is equivalent to the fraction represented by this picture
Step-by-step explanation:
20/100 simplified is 2/10
The graph also contains the right amount of boxes to represent 2/10 or 20/100

Assume that this is a random sample.
A formal hypothesis test was carried out to compare the observed and expected frequencies of genotypes. The procedure obtained P = 0.0001.
1. "The frequency distribution of genotypes has a binomial distribution in the population" is the________ hypothesis, whereas "The frequency distribution of genotypes does not have a binomial distribution" is the _________ hypothesis.
2. The degrees of freedom for the test statistic are __________.
Say whether the each of the following statements is true or false solely on the basis of these results:
3. The difference between the observed and expected frequencies is statistically significant.________
4. The test statistic exceeds the critical value corresponding to α = 0.05. ___________
5. The test statistic exceeds the critical value corresponding to α = 0.01. ____________
Answer:
1) i ) Null hypothesis, ii) Alternate hypothesis
2) Degree of Freedom = 14.9011
3) True
4) True
5) True
Step-by-step explanation:
1) "The frequency distribution of genotypes has a binomial distribution in the population" is the NULL hypothesis, whereas "The frequency distribution of genotypes does not have a binomial distribution" is the ALTERNATE hypothesis.
2) Degrees of freedom: see attached calculation for
3) True, the difference between the observed and expected frequencies is statistically significant since p-value < ∝alpha(0.05)
4) True
when, 14.9011 > 3.8415 where ∝ = 0.05
when, p-value < alpha,TS > critical value
here p-value < 0.0001 < 0.05
5) True
when, 14.9011 > 6.635 where ∝ = 0.01
when, p-value < alpha,TS > critical value
here p-value < 0.0001 < 0.01
The null hypothesis states that the genotype frequency distribution follows a binomial distribution, with the alternative hypothesis stating the contrary. The degrees of freedom for the test statistic are two. The P value of 0.0001 is statistically significant, thus the test statistic exceeds the critical values corresponding to both α = 0.05 and α = 0.01.
1. The frequency distribution of genotypes has a binomial distribution in the population is the null hypothesis, whereas The frequency distribution of genotypes does not have a binomial distribution is the alternative hypothesis.
2. For this chi-square test, since there are 3 possible outcomes (BB, Bb, bb) the degrees of freedom are 3-1 = 2.
3. The difference between the observed and expected frequencies is statistically significant, that is true. A P value of 0.0001 is highly significant, clearly less than 0.05, and denotes a significant difference.
4. The test statistic exceeds the critical value corresponding to α = 0.05. This is true, as the statistically significant low P value indicates the test statistic is in the critical region.
5. The test statistic exceeds the critical value corresponding to α = 0.01. This is also true.

Answer:
To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.
Step-by-step explanation:
The area of any quadrilateral can be determined by multiplying the length of its base by its height. Since we know the shape here is square, we know that all sides are of equal length. From this we can work backwards by taking the square root of the area to find the length of one side. hope this helps you :)

The greatest common factor of 4xy² and 20x2y^4 is: 4xy².
Greatest common factor of a set of terms is the factor that all terms in the set share together.
Given:
4xy² and 20x2y^4
4xy² can divide both terms, meaning both terms share a factor.
Therefore, the greatest common factor of 4xy² and 20x2y^4 is: 4xy².
