Answer:
-249387
Step-by-step explanation:
1) Write out the problem
-5+-10-41562*6
2) Following order of operations, multiply -41562 by 6:
-5+-10-249372
3) Solve -5+-10:
-15-249372
4) Subtract:
-249387
Multipy the hight with the width, just like you would if it was a square, because if you were to cut off one sides with a slant, and place it on the opposite side it would make a square and it wouldn’t affect the area.
Answer:
89.008
Step-by-step explanation:
z = (x– mean)/ standard deviation
x = z * standard deviation + mean
Now, z value for the top 4% of the exams (which is the same as getting a score below the 96%) has to be found using a z table.
In this case z = 1.751
x = 1.751 * 8 + 75
x = 89.008
Answer:
see explanation
Step-by-step explanation:
Using the trig identity
sin²x + cos²x = 1 , then
sin²x = 1 - cos²x
cos²x = 1 - sin²x
Consider the left side
sin²A - cos²B
= (1 - cos²A) - (1 - sin²B) ← distribute parenthesis
= 1 - cos²A - 1 + sin²B
= sin²B - cos²A
= right side , thus verified
