In 2012 Staci invested $14,500 in a savings account for her newborn son. The account pays 3.6% interest each year. Determine the accrued value of the account in the year 2030, when her son will go to college. Round your answer the nearest cent.
In the year 2030, the accrued value will be $
Answer: $23,896
Step-by-step explanation:
In the year 2030, the number of years since the investment would be;
= 2030 - 2012
= 18 years.
As the question does not mention that the interest paid is compounded, simple interest will be used;
= Amount + (Amount * interest rate * number of years).
= 14,500 + ( 14,500 * 0.036 * 18)
= $23,896

Show all your work. Indicate clearly the methods you use, because you will be scored on the correctness of your methods as well as on the accuracy and completeness of your results and explanations. Kathy and her brother Clay recently ran in a local marathon. The distribution of finishing time for women was approximately normal with mean 259 minutes and standard deviation 32 minutes. The distribution of finishing time for men was approximately normal with mean 242 minutes and standard deviation 29 minutes. The finishing time for Clay was 289 minutes. Calculate and interpret the standardized score for Clayâs marathon time. Show your work.
Answer:
Clay's finishing time is 1.68 standard deviation above the mean finishing time for men.
Step-by-step explanation:
In statistics, a standardized score is the number of standard deviations an observation or data point is from the mean.
Let us consider a random variable, X that follows a normal distribution, N (µ, σ²).
Then Z is a standard normal variate with mean, E (Z) = 0 and Var (Z) = 1. That is,
[tex]Z=\frac{x-\mu}{\sigma}\sim N(0, 1)[/tex]
This, z-score is known as the standardized score.
It is provided that the distribution of finishing time for men (say, X) was approximately normal with mean µ = 242 minutes and standard deviation σ = 29 minutes.
The finishing time for Clay was x = 289 minutes.
Compute Clay's z-score as follows:
[tex]Z=\frac{x-\mu}{\sigma}[/tex]
[tex]=\frac{289-242}{29}\\\\=1.67857143\\\\\approx 1.68[/tex]
Thus, Clay's standardized score is 1.68.
That is, Clay's finishing time is 1.68 standard deviation above the mean finishing time for men.

John bought a car for $36,000, he didn't have enough money to buy the car totally, so he gave $1000 monthly, how much money did he give after 1 year, and how much does he has to give more?
There are twelve months in a year, and he pays $1000 a month, so we get [tex]\$1000*12 = $12,000[/tex] spent in a year. He originally needed to spend $36,000, so he has [tex]\$36,000-\$12,000 = \$24,000[/tex] left.
Please mark as Brainliest if you found this helpful.
Answer:
He payed 12,000 in one year
John has to pay $24000
Step-by-step explanation:
Car cost = $36,000
He gave Monthly = $1000
How much money did he give in a year?
1 year = 12 months
So
$1000 x 12 = 12,000
How does he have balance?
$36,000 - $12,000 = $24,000
John payed $12000 in one year, and has to pay $24000 more to own the car.

The baker has 42 kilograms of flour. She uses 8 kilograms each day.after how many days will she need to buy more flour?
Answer:
5 days 6hours
Step-by-step explanation:
Given data
total amount of flour=42kg
number of kg used per day=8kg
Since we are expected to know when she will need more, we need to divide the total flour by the daily usage, to know when the flour we be exhausted
divide 42 by 8 we have
42/8=5.25------0.25 days to hours is 6hours
So it will take 5 days 6hours

The Air Quality Index, or AQI, measures how polluted the air is in your city and assigns a number based on the quality of the air. Over 100 is “Unhealthy”.
The following quadratic regression equation gives us an estimate of n, which is the number of days the AQI exceeded 100 a particular year. We will use this equation to estimate the number of days the AQI was over 100 in the year 1995.
n = 1.76 t squared minus 13.32 t + 41.00
(Let t represent the number of years since 1990. Therefore, t = 0 corresponds to the year 1990. For the estimate of n, round to the nearest whole day.)

Judy’s Cake Shop makes fresh cakes to customer orders. After receiving the order by Judy’s assistant, which takes 2 minutes, Judy then takes 8 minutes to mix the ingredients for the cake and loads a cake pan for baking. Then the cake is put into the oven for 30 minutes. The oven can hold three cakes at one time. When the cake is taken out of the oven, it is cooled for 1 hour. The assistant then takes 2 minutes to pack the cake for pickup and bills the customer, which takes 3 minutes. a. What is the capacity of the process, and what is the bottleneck? b. What is the throughput time for a typical cake? c. If on average five orders are taken per hour, how many cakes are there in the process (on average)?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Time taken to receive order = 2 minutes
Ingredient mixing and cake loading = 8 minutes
Baking time = 30 minutes
Number of cakes oven can hold at a time = 3
Cooling time = 1 hour = 60 minutes
Cake packing = 2 minutes
Billing customer = 3 minutes
a. What is the capacity of the process, and what is the bottleneck?
The capacity of the process:
Within an hour : two bakings can be done =(30 minutes * 2) = 60 minutes
Also oven can hold 3 cakes, so, 3 cakes can be baked at a time.
Hence, 3 cakes in 30 minutes ;
6 cakes in an hour;
Hence, capacity of the process is 6cakes per hour.
The bottleneck is the oven, because if the number of ovens were to be increased, the process capacity will increase, similarly, if one of the oven gets faulty, then the process capacity reduces further.
b. What is the throughput time for a typical cake?
The throughput time, is the summation of all the time taken to fully complete an order :
Receipt of order + mixing + baking + cooling + packing + billing
2 + 8 + 30 + 60 + 2 + 3 = 105 minutes
c. If on average five orders are taken per hour, how many cakes are there in the process (on average)?
(Throughput time / 60) * average number of order
(105/60) * 5
= 1.75 * 5
= 8.75
In the following diagram which is not drawn to scale, why can't both line AB and line AC be perpendicular to line BC?
Answer:
AC and AB both can't be perpendicular to line BC because if they were, then AB and AC would be parallel to each other and would never intersect. In this diagram, AB and AC intersect, so it it not possible.
Perpendicular lines meet at a right angle.
AB and AC cannot be perpendicular to BC because AB and AC are not parallel
From the diagram, we can see that line AB and line AC intersects at point A.
This means that both lines are not parallel
For any two lines to be perpendicular to a third line, the two lines must be parallel to each other.
So, we can conclude that:
Lines AB and AC cannot be perpendicular to line BC because both lines are not parallel.

Graph 1
coordinates : (0,-5) (-6,-2)
m = (y2-y1)/(x2-x1)
m = (-2-(-5))/(-6-0)
m = 3/-6 = -1/2
Substitute the values,
y = mx + c
-2 = (-1/2)(-6) + c
-2 = 3 + c
c = -5
Thus, equation is y = -1/2x -5
Graph 2
coordinates : ( 4,-2) (-5,3)
m = (y2-y1)/(x2-x1)
m = (3-(-2))/(-5-4)
m = 5/-9
Substitute the values,
y = mx + c
-2 = (-5/9)(4) + c
-2 = -20/9 + c
c = 2/9
Thus, the equation is y = -5/9 + (2/9)
