Answer:
f(n) = 1750 + 70n
Step-by-step explanation:
Since, each of them are depositing 35$ each month, they are adding 35x2 = 70$ each month.
So, in n months, they will be adding 70n $ to their account.
Initially, they had 1,750$ in their account. After n months, they should have 1750+70n $ in their account.
So, the function that represents this is, f(n) = 1750 +70n

Step-by-step explanation:
x P(x) 
33 0.02 0.66 21.78
34 0.06 2.04 69.36
35 0.1 3.5 122.5
36 0.2 7.2 259.2
37 0.24 8.88 328.56
38 0.26 9.88 375.44
39 0.1 3.9 152.1
40 0.02 0.8 32
1 36.86 1360.9
We are supposed to find mean and standard deviation
Mean =
Standard deviation =
Answer:
<em>x </em>= 128°
Step-by-step explanation:
Its an isosceles triangle, so it has 2 two sides of equal length. and from here we can say that it has two angles that are the same, 26° and 26° we know that in a triangle there are 180° in total so we add up the two angles we know 26+26=52 and subtract it by 180 which equals 128°
Answer:
<em>n = 8 or n = −2</em> <em>is the correction solution.</em>
Step-by-step explanation:
As the absolute value equation is given:
| n−3 | = 5
We know either n − 3 = 5 or n − 3 = −5
n − 3 = 5 (First Possibility)
n − 3 + 3 = 5 + 3
n = 8
n − 3 = -5 (Second Possibility)
n = -5 + 3
n = -2
<em> So, n = 8 or n = −2</em> <em>is the correction solution.</em>
