How do u solve this pls help

A cell divides through mitosis, creating two daughter cells. Which of the following is true about the daughter cells?

White raven [17]

Hello!

Your answer is A. The daughter cells are genetically identical to both each other and to the parent cell.

The parent cell makes two copies of its chromosomes and separates them, then divides by cytokinesis, creating two genetically identical daughter cells.

A seamstress needs to cut 15-inch pieces of ribbon from a roll of ribbon that is 9 feet in length. What is the greatest number o

Eduardwww [97]

Before attempting to solve any problem, make sure that the units are consistent. There are units of feet and inches. To be consistent,let's convert ft to in knowing that there are 12 inches in 1 ft.

9 ft*12 in/1 ft = 108 inches

Now, it also mentions that there are 5 of these. So, the total length would be:
Total Length = 108*5 = 540 inches

Finally, divide the total length to 15 inches.

Number of portions = 540/15 = <em>36 pieces of 15-inch ribbons</em>

f the dean wanted to estimate the proportion of all students receiving financial aid to within 3% with 99% reliability, how many

Oksanka [162]

Answer:

n=1849

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The population proportion have the following distribution

$p \sim N(p,\sqrt{\frac{p(1-p)}{n}})$

Solution to the problem

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 99% of confidence, our significance level would be given by $\alpha=1-0.99=0.01$ and $\alpha/2 =0.005$ . And the critical value would be given by:
