Answer:
The answer is b.) -5.2 degrees
Step-by-step explanation:
to find the mean of this problem you have to add all numbers and then divide it by how many numbers there is.
so you have to add -42+ -17+14+-4+23 and that'll equal -26
so you take -26 and divide it by 5 because thats how many numbers their are to divide
-26 divided by 5 is (-5.2)
n, n+1 - two consecutive integers
n(n + 1) = 50 <em>use distributive property</em>
n² + n = 50 <em>subtract 50 from both sides</em>
n² + n - 50 = 0
-----------------------------------------------------
ax² + bx + c =0
if b² - 4ac > 0 then we have two solutions:
[-b - √(b² - 4ac)]/2a and [-b - √(b² + 4ac)]/2a
if b² - 4ac = 0 then we have one solution -b/2a
if b² - 4ac < 0 then no real solution
----------------------------------------------------------
n² + n - 50 = 0
a = 1, b = 1, c = -50
b² - 4ac = 1² - 4(1)(-50) = 1 + 200 = 201 > 0 → two solutions
√(b² - 4ac) = √(201) - it's the irrational number
Answer: There are no two consecutive integers whose product is 50.
Sure buddy! -4/9 + 1/2 is 1/8 in exact form. In decimal form it is 0.05 (bar notation over 5)
