Answer:
Step-by-step explanation:
2 equal 90° angles, we can use an equation
x + 15 = 90
x = 90 - 75
x = 15°
-------------------------
check
90 = 15 + 75
90 = 90
the answer is good
3n + 7 = 49
3n = 42
n = 14
answer
the number is 14
Answer:
P = 0.688
Step-by-step explanation:
Since x= 1764, n = 2565
95%. CI= ( 0.670, 0.706)
a) P= x/n
P = 1764/2565
P = 0.688
(a+b)^7= a^7+ 7a^7b+ 21 a^6b²+ 35a^5b³+ 35 a⁴b⁴+ 21 a³b^5 + 7a²b^6 + b^7
40,561÷ 47= 863
Hoped this helped.
