Answer:
2.5
Step-by-step explanation:
E(x) = sum[x + p(x)]
= (0)(0.05) + (1)(0.1) + (2)(0.3) + (3)(0.4) + (4)(0.15)
= 2.5

From the given table, the positive sign connote deposit while the negative sign connotes withdrawal.
If the account shows a zero balance after 4 weeks, we will take the sum of all deposits and withdrawals for the first four weeks and equate to zero as shown:
Open the parenthesis:
Subtract 70 from both sides
Hence the value of p if the account shows a zero balance after 4 weeks is -70

Answer:
First of all, we can see that this shape have 4 90° angles.
Secondly, since x = 5 we have:
3 × 5 -2 = 15 - 2 = 13 (cm)
And: 5 + 8 = 13 (cm)
=> The two adjacent sides that make up the angle is equal to each other
So this shape is a quare.
=> This shape is a square.
