11. Cell 2, because it has a cell wall AND a cell membrane
12. Letter J, it is pointing to the layer around the cells inner parts
13. Letter A, it is pointing to the space inside the cell membrane. The cytoplasm is what fills the cells
14. Letter B, because chloroplasts are only found in the Plant cell
15. I’m pretty sure Letter K is the mitochondria. It is the powerhouse of the cell and without the cell would not function.

Please answer full question below thank you

Yuliya22 [10]

Explanation:

Angles 1 & 2 have to equal 180. So, if ∠1 is equal to 140, ∠2 is equal to 40 because 140 + 40 = 180.

So far... we know that:

∠2 = 40
∠9 = 80

Angles 2, 9, and 11 make a triangle, a triangles "magic number" is also 180. To get 180, you must add up all of the angles. Well... we don't know ∠11 so to find it, you subtract 40 & 80 from 180. 180 - 80 - 40 = 60.

Answer:

∠2 = 40

∠11 = 60

In 1990, 23.8% of 18-24 year-olds in Biddeford, Maine were attending college. About 10 years later, a random sample of 610 18-24

Vlada [557]

Answer:

There is enough evidence to support the claim that the percentage of residents attending college in that age-group is greater than 23.8%

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 610

p = 23.8% = 0.238

Alpha, α = 0.01

Number of 18-24 year-old attending college , x = 178

First, we design the null and the alternate hypothesis

$H_{0}: p = 0.238\\H_A: p > 0.238$

This is a one-tailed(right) test.

Formula:

$\hat{p} = \dfrac{x}{n} = \dfrac{178}{610} = 0.2918$

$z = \dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}$

Putting the values, we get,

$z = \displaystyle\frac{0.2918-0.238}{\sqrt{\frac{0.238(1-0.238)}{610}}} = 3.1201$

Now, we calculate the p-value from the table.

P-value = 0.0009

Since the p-value is lower than the significance level, we fail to accept the null hypothesis and reject the null hypothesis.

Conclusion:

Thus there is enough evidence to support the claim that the percentage of residents attending college in that age-group is greater than 23.8%

Gabrielle's age is two times Mikhail's age. The sum of their ages is 45. What is Mikhail's age?

Fittoniya [83]

Answer:Gabrielle is 2*Mikhail:

G = 2M We will use this value for G next

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

G+M = 45 Now in this equation substitute for G, like this:

2M+M = 45

3M = 45 Divide both sides by 3

M = 15 This is Mikhail, and the problem says that:

G = 2(15) = 30

Gabrielle is 30 and Mikhail is 15, and 15+30 = 45 just like the problem says
