Answer:
Algebra tiles would not be a good tool to use to factor because you would need to drag an x-squared tile, 18 x-tiles, and 80 plus tiles and it would take a lot of time to drag that many tiles on the board and there might not be enough space to hold all of them. and do u have time to drag 80 tiles? lol
Step-by-step explanation:
32 meters tall.
It would form a right triangle, in which the shorter leg is 7m and the longer leg is 24m. You're looking for the last side, the hypotenuse. So use the Pythagorean theorem. a^2 + b^2 = c^2 , in which a and b are the legs and c is the hypotenuse.
Therefore, you get 7^2 + 24^2 = c^2.
Which is, 49 + 576 = c^2
Add, 625 = c^2.
Take the square root of 625, which is 25. So, the length of the hypotenuse (last side) is 25m. Add the 7m that is sticking out of the ground, to get 32m.
Answer: 1.282
Step-by-step explanation:
Given : Significance level : 
The alternative hypothesis : 
, which is left tail-ed , it means the test is left -tailed test i.e. one -tailed test.
By using the standard normal distribution table , we have
The critical value for a one-mean z-test corresponding to the significance level 0.10 is 1.2815515 or approximately 1.282
Hence, the critical value or values for a one-mean z-test at the 10% significance level if the hypothesis test is left-tailed = 1.282
20, 21, 29
Explanation:
Use the Pythagorean Theorem
20^2 + 21^2 = 29^2
400 + 441= 841
841 = 841
