Sarah invested $3,800 in an account paying an interest rate of 3.6% compounded daily. Assuming no deposits or withdrawals are made, how much money, to the nearest hundred dollars, would be in the account after 15 years?
Answer:
6500
Step-by-step explanation:
A=P(1+nr)nt
Compound interest formula
P=3800
r=0.036
t=15
n=365
P=3800r=0.036t=15n=365
Given values
A=3800 (1+0.036 365)
365(15)
A=3800(1+365 0.036)
365(15)
Plug in values
A=3800(1.0000986301) 5475
A=3800(1.0000986301)
5475
Simplify
A=6520.65243954
A=6520.65243954
Use calculator
A≈6500
A≈6500
Round to nearest hundred
The amount in account after 15 years will be $6500
What is compound interest ?Compound interest is the interest you earn on interest.
Given that, Sarah invested $3,800 in an account paying an interest rate of 3.6% compounded daily.
Compound interest formula;
A = P(1+r/n)^nt
We have,
P = 3800
r = 0.036
t = 15
n = 365
P = 3800 r = 0.036 t = 15 n = 365
Putting the values and on simplification, we get,
A = 3800(1+0.036 365)365(15)
A = 3800(1+365 0.036)365(15)
A = 3800(1.0000986301)5475
A = 3800(1.0000986301)5475
A = 6520.65243954
A = 6520.65243954
A ≈ 6500
A ≈ 6500
Hence, The amount in account after 15 years will be $6500

75%75, percent of the pot's volume.
How far up the pot will the soil reach?
Round to the nearest tenth.
Answer:
The soil will occupy in 11664cm³ of the pot which is 3/4 or 0.75 of the squared based pyramid pot.
Step-by-step explanation:
The volume of a square based pyramid = V = a²h/3
a = base edge or side length = 36cm
h = height = 36cm
V = 36² × 36/3
V = 15552cm³
Luis wants to fill the pot with soil so that the soil takes up 75 % the pot's volume.
75% of the pot's volume =
75/100 × 15552cm³
= 11664cm³
The soil will occupy 11664cm³ of the pot which is 3/4 or 0.75 of the squared based pyramid pot.
Answer:
The soil will reach about 32.7 cm up the pot.

Answer:
C) 18
Step-by-step explanation:
All you have to do is solve the equation.
2.25x + 5 = 45.50 (subtract 5 on each side)
2.25x = 40.50 (divide by 2.25 on both sides to get the x alone)
x = 18
40.50/2.25 = 18
Answer:
18 Miles
Step-by-step explanation:
If she tipped the driver $5, we need to remove that from the equation. So it's now $40.5.
Now to find the answer all we need to do is divide 40.5 by 2.25, which is 18.

Consider 3 trials, each having the same probability of success. Let X denote the
total number of successes in these trials. If E(X) = 1.8, the smallest possible value of Pr{X = 3}?
Construct a probability scenario that results in Pr{X = 3} having the stated value.
(Hint: For part (b), you might start by letting U be a uniform random variable on (0,1) and then defining the trials in terms of the value of U.)
Solve using hint
Answer:
The smallest possible value of Pr{X = 3} is U = 0
Step-by-step explanation:
The number of trial is n = 3
The mean is E(X) = 1.8
Gnerally given that every probability value lies between 0 and 1 ,
let U be the smallest possible value of Pr{X = 3}
it then mean that U= 0 because in the range which probability values can take , the smallest value is zero
So
The smallest possible value of Pr{X = 3} is U = 0

What’s the y-intercept of the line graphed on the grid?
Answer:
y-intercept is 4.5
Step-by-step explanation:That is when the line intersects the y-axis
Answer:
y intercept = 5.5
Step-by-step explanation:
The y-axis is the vertical (up and down) line in the center of the graph. When the line passes over it, wherever it passes, will be your y intercept.
In this situation it passes in the middle of 5 and 6 so it would be 5.5.

Which scenario is an example of the transfer of thermal energy by radiation?
A. Leftovers are warmed in a microwave oven.
O B. A person's body temperature falls as the person swims in the
ocean.
C. Warm air near a heater spreads out to the rest of the room.
D. A piece of chocolate melts in a person's hand.
Answer:
A
Step-by-step explanation:
The scenario that is an example of the transfer of thermal energy by radiation is warm air near a heater spreads out to the rest of the room. That is option C.
What is radiation?Radiation is the transfer of heat energy from an environment to another through movement of air in the space between them. There is no medium that is required for this transfer.
From the options, the warm air from the heater spreads out to the rest of the room through the movement of air.
Therefore, the scenario that is an example of the transfer of thermal energy by radiation is warm air near a heater spreads out to the rest of the room.

Two secant segments are drawn to a circle from a point outside the circle. The external segment of the first secant segment is 8 centimeters and its internal segment is 6 centimeters. If the entire length of the second secant segment is 28 centimeters, what is the length of its external segment?
Given:
Two secant segments are drawn to a circle from a point outside the circle.
External segment of the first secant segment = 8 centimeters
Internal segment of the first secant = 6 centimeters.
Entire length of the second secant segment = 28 centimeters.
To find:
The length of its external segment.
Solution:
Let x be the length of its external segment.
Entire length of the first secant segment = 8+6 = 14 centimeters.
If two secant segments are drawn to a circle from a point outside the circle, then product of entire length of first secant and external length of first secant is equal to product of entire length of second secant and external length of second secant.
[tex]14\times 8=28\times x[/tex]
[tex]112=28x[/tex]
Divide both sides by 28.
[tex]\dfrac{112}{28}=x[/tex]
[tex]4=x[/tex]
Therefore, the length of external segment of second secant is 4 centimeters.
