Answer:
x = 6
Step-by-step explanation:
From the given picture,
ΔABC and ΔADE are the similar triangles.
By the property of similar triangles,
Corresponding sides of the similar triangles are proportional.
[tex]\frac{AB}{AD}=\frac{AC}{AE}[/tex]
[tex]\frac{x+18}{x}=\frac{28}{(28-21)}[/tex]
7(x + 18) = 28x
7x + 7×18 = 28x
28x - 7x = 126
21x = 126
x = [tex]\frac{126}{21}[/tex]
x = 6

Answer:
Unlike most circle graphs, bar graphs compare exact amounts. Circle graphs are used when dealing with percentages, and the percentages of the pieces add up to 100 percent. In a bar graph, however, a scale is used to show the exact amount of each category. ... The bar graph shows the same results but in a different format.

Answers
Step-by-step explanation: Go.dzilla 2 king of monsters is one of the best movies out there in my opinion, right down to the CGI, the movie makers did a fantastic job of creating an emotional attachment to the family in the movie.
Basically in the movie it starts in a nuclear power plant, the power plant has a melt down, kil.ling the team that went into the core to see what the issue was, the director of the power plants wife died and he knew that it wasn.t normal for the plant to meltdown the way it did, so he dedicates the rest of his life to trying to figure out what really happened there. He even goes as far as to sneak in to the restricted area with his son, when there they find out that they are digging up something from the wreckage, this is the giant moth (it wont let me say the name), The giant moth was feeding on the nuclear radiation and that was what caused the plant to melt down all those years ago. the giant moth then flies across the country searching for nuclear radiation and in turn waking her mate and destroying the place, this awakens Go.dzilla so that he can reassert himself as the ap.ex predator. He finds both the giant moths and kil.ls them and then returns to the bottom of the ocean.

Please mark as brainliest for further answers :)A student’s AP statistics project involves comparing the time it takes a student to complete a set of 25 basic trinomial factoring problems while listening to either rap music or country music. Twelve students are timed on two different sets of problems of equal difficulty. The order of which set of problems he does first and which music he listens to first are randomized. The resulting data is thus paired, with each student acting as his own "pair." Which of the following conditions is required to perform a t-test on these paired data?
A. The distribution of times for all students on each set of problems must be approximately Normal.
B. The distribution of times for all students while listening to each type of music must be approximately Normal.
C. The distribution of times for all 24 sets of problems (12 students are taking 2 tests each) must be approximately Normal.
D. The distribution of differences between each individual student’s times on each of the two tests (time with rap – time with country) must be approximately Normal.
Answers
Answer:
D. The distribution of differences between each individual student’s times on each of the two tests (time with rap – time with country) must be approximately Normal.
Step-by-step explanation:
For a paired test, there are two measured values of a particular point, here what is measured is the time taken for each of rap and country music by each student.
The difference :
t2 - t1 = time with rap music - time with country music.
The number of samples usually associated with t distribution is usuall y very small (n ≤ 30).

[tex]\sqrt{45}[/tex]
Step-by-step explanation:
Hi there,
In order to solve this problem, you have to know the Pythagorean Theorem:
[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
We can see from the graph that line segment ML and LN are 6 and 3 units respectively. Since we know the lengths of two sides of the triangle, we can use the theorem above to find the hypotenuse (MN).
⇒ [tex]6^{2}[/tex] + [tex]3^{2}[/tex] = [tex]c^{2}[/tex]
⇒ 45 = [tex]c^{2}[/tex]
⇒ c = [tex]\sqrt{45}[/tex]
Hope this explanation helps. Cheers.
