Answer:
this is an obtuse angle and an isosceles triangle
because angle is greater than 90° and two sides are equal.
Answer:
it's either a= −3b−c/2
Or b=
−2a−c/3
Step-by-step explanation:
Not sure and s-u-p-e-r late lol-
Five consecutive integers are:
n, n+1, n+2, n+3, n+4 the sum of which is:
5n+10=265 subtract 10 from both sides
5n=255, divide both sides by 5
n=51
Our fifth number was n+4 so the fifth number is 55
The critical value is z=1.88.
We find this by first converting the percent confidence we want to a decimal: 94% = 94/100 = 0.94
We subtract that from 1 to find the alpha level:
1-0.94 = 0.06
Divide this by 2 (to find the area in each tail):
0.06/2 = 0.03
Subtract this from 1 again (because we want the area in the middle, not in each tail):
1 - 0.03 = 0.97
Using a z-table (http://www.z-table.com) we see that the closest to this in the table is at z = 1.88.
