Step-by-step explanation:
mean is average, so if we label the first through fifth days of january a-e we can solve it.
So average of the first four is (a+b+c+d)/4 = 1 and the first five is (a+b+c+d+e)/5 = 2. Since it's easy, let's get rid of the fraction in both.
(a+b+c+d)/4 = 1 and (a+b+c+d+e)/5 = 2
a+b+c+d = 4 and a+b+c+d+e = 10
Now, we know a+b+c+d is 4, so we can replace that in the second equation
a+b+c+d+e = 10
4 + e = 10
e = 6
ad since e is the fifth day, we know the temperature of it. Let me know if something here didn't make sense.
<u><em>Answer: -2/5+1/5i</em></u>
Explanation:
complex rule.
(-3*7+1*1)+(1*7-(-3)*1)i/7²+1² ← as the fractions
then refine and rewrite the problem down.
-20+10i/50 ← as the fractions shown.
-20+10i/50=-2+i/5
you can also rewrite the problem down in standard complex form.
-2+i/5=-2/5+1/5i
<u><em>=-2/5+1/5i</em></u>
Hope this helps!
Thanks!
Have a great day!
2x + 8 is the answer because you add the x and the numbers and turn it into an equation
Answer:
v = 60
Step-by-step explanation:
65 + 55 + v = 180
65 + 55 = 120
180 - 120 = 60
v = 60
