Answer:
Option A and option B
Step-by-step explanation:
Given that
Sophia wants to invest $6,000
There are two investment options
Option A pays 2.2% simple interest
and, Option B pays 2% interest compounded annually
Now we need to find out which option is the best choice
In the case when Sophia wants to invest for 10 years, so she should select
option A as the investment will have highest value.
In the case when Sophia wants to invest for 20 years, so she should select
option B as the investment will have highest value.
Answer:
<h3>p = 131.25</h3>
Step-by-step explanation:
The variation p varies directly with T is written as
p = kT
where k is the constant of proportionality
To find p when T =500 we must first find the formula for the variation
That's
when p = 105 and T = 400
105 = 400k
Divide both sides by 400
<h3>
</h3>
So the formula for the variation is
<h2>
</h2>
when
T = 500
Substitute it into the above formula
That's
Simplify
The final answer is
<h3>p = 131.25</h3>

Answer:
The answer is B. 6 feet.
Step-by-step explanation:
To solve this problem, we must remember that the formula for area of a square is given by A = s^2, where s represents the length of one of the sides.
Since we are given that the area of the square is 36, we can substitute this into the formula to get:
36 = s^2
Then, to solve for s, we should take the square root of both sides, which gives us:
s = 6
Therefore the correct option is B. 6 feet.

Answer:
the probability that a randomly chosen test-taker will score 142 or lower = 0.8643
Step-by-step explanation:
We are given;
Data point; x = 142
Mean; μ = 153
Standard deviation; σ = 10
So,let's find the z-score using;
z = (x - μ)/σ
z = (142 - 153)/10
z = -1.1
From the z-distribution table attached, the probability is;
P(z < -1.1) = 1 - 0.13567 ≈ 0.8643
-30+(-40)+(-70) = -140
A) 140
B) 0
C) -60
D) -140
So your answer would be D
