Answer:
6
+ 5x² - 2x + 3
Step-by-step explanation:
Given
( + 2x² - 4) - (-5 - 3x² + 2x - 7)
Remove the parenthesis on the first factor and distribute the second by - 1
= + 2x² - 4 + 5 + 3x² - 2x + 7 ← collect like terms
= 6 + 5x² - 2x + 3 ← in standard form
Wouldn't it be (d+24)divided by 4?
Answer:
60-32i
Step-by-step explanation:
(8-2i)^2=8^2-2.8.2i+(2i)^2
=64-32i+4i^2
=64-32i-4
=60-32i
Answer:
1) 24.2 = x 2) 27.8 = x
Step-by-step explanation:
1) Find the cos 21 degrees
cos 21 = x/26 Simplify
0.93 = x/26 Multiply 0.93 and 26
24.2 = x
2) Find the sin 33 degrees
sin 33 = 15/x Simplify
0.54 = 15/x Divide both sides by 0.54
27.8 = x

Answer:
100%
Step-by-step explanation:
Use conditional probability:
P(B | A) = P(B and A) / P(A)
P(B | A) = (12/28) / P(A)
We need to find the probability that a student studies art.
P(A or B) = P(A) + P(B) − P(A and B)
24/28 = P(A) + (12+12)/28 − 12/28
P(A) = 12/28
P(B | A) = (12/28) / (12/28)
P(B | A) = 1
What this means is that all of the students who study art also study biology.
