Answer:
$10,857.8
Step-by-step explanation:
Brad wants to have $17000 available to buy a car in 5 years. How much should he deposit now at 9% compounded monthly to reach that goal?
A = p(1 + r/n)^nt
P = A / (1 + r/n)^nt
P = 17000 / (1 + 0.09/12)^(12*5)
= 17,0000 / (1 + 0.0075)^60
= 17,000 / (1.0075)^60
= 17,000 / 1.5657
= 10,857.8
P = $10,857.8

The cafeteria bought 200 French bread pizzas for lunch next week. If they had bought the pizza last week while it was on sale, it would only have cost $ 2.00 per pizza. Now, 7 days later, the price is $ 3.78 per pizza. How much money could they have saved if they bought the pizza last week?
Answer:
$356
Step-by-step explanation:
To solve this problem, use this: (200 * 3.78) - (200 * 2)
(200 * 3.78) - (200 * 2)
200 * 3.78 is the same as 2 * 378, which is 756.
756 - (200 * 2)
200 * 2 is the same as 4 * 100, which is 400.
756 - 400
Subtract 400 from 756 to get 356.
356
If they brought the pizza last week, the school could have saved $356.

cos(0)=2/2 ,and <0<2pi, evaluate sin(0) and tan(0). sin (0)=? tan(0)=?
PLEASE HELP!!!!
Answer:
Step-by-step explanation:
The angle is between 3pi/2 and 2pi so it is in the fourth quadrant where both sin and tan are negative.
Given cos(θ) = sqrt(2)/2
cos^2(θ) + sin^2(θ) = 1
sine^2(θ) = 1 - 2/2^2 = 1 - 1/2 = 1/2
sin(θ) = +/1 sqrt(2)/2
As we know sin(θ) is negative,
sin(θ) = -sqrt(2)/2; the second answer
tan(θ) = sin(θ)/cos(θ) = -1
Answer:
Step-by-step explanation:
using (cosθ)^2 + (sinθ)^2 = 1
2/4 + (sinθ)^2 = 1
sinθ = [tex]\sqrt{2}/2[/tex]
or -[tex]\sqrt{2} /2[/tex]
By C-A-S-T, sinθ is -ve
sinθ = -[tex]\sqrt{2}/2[/tex]
tanθ = sinθ/cosθ = -1
Gabriele's Pie Shop sold 80 pies last month: 7/10 were apple pies and 1/10 were peach pies. How many pies were neither apple nor peach?
a.)40
b.)32
c.)16
d.)9
Answer:
16 pies were neither apple nor peach.
Step-by-step explanation:
8/10, or 4/5 of the 80 apple pies were either apple or peach, which 4/5 of 80 is 64. The remaining pies will be neither apple nor peach. 80 - 64 = 16.

You receive an A 40% of the time, a B 20% of the time, a C 15% of the time , and a D the rest of the time. For any random test, what is your expected grade point average? (Use the following values for X: A=4, B=3, C=2, D=1)
The grade you receive on a test is a discrete random variable with probability mass function
[tex]f_X(x)=P(X=x)=\begin{cases}0.4&\text{for }X=4\text{ (i.e. scoring an A)}\\0.2&\text{for }X=3\text{ (B)}\\0.15&\text{for }X=2\text{ (C)}\\0.25&\text{for }X=1\text{ (D)}\\0&\text{otherwise}\end{cases}[/tex]
where the probability of getting a D is 25% because there are only 4 possible grades, and the probabilities must sum to 1 :
0.4 + 0.2 + 0.15 + 0.25 = 1
The expected test score/GPA is then
[tex]\displaystyle\sum_x x\,f_X(x)=\sum_{x=1}^4 x\,P(X=x)=1\cdot0.25+2\cdot0.15+3\cdot0.2+4\cdot0.4=\boxed{2.75}[/tex]
so your average would fall between a B and a C.

In a bag there are 3 red marbles, 2 yellow marbles and 1 blue marble. After a marble is selected, it is replaced. After 40 attempts at drawing two marbles from the bag, there were three instances where a blue marble then a yellow marble was pulled. What is the percent difference between the theoretical probability and the experimental probability?
75%
26%
56%
35%
Answer:
35%
Step-by-step explanation:
The percent error can be found using the
|Experimental value - Theoretical value| divided by |Theoretical value| and multiplied by 100.
I hope this helps
Here, the experimental probability is 1/4 and theoretical probability is 1/18.Then the percent difference between the theoretical probability and the experimental probability is 56%.
What is probability ?The probability is a measure of chances that an event to take place.
Given that,
red marbles = 3
blue marbles =1
yellow marbles = 2
Then.
theoretical probability of selecting a blue marble followed by a yellow marble is:
P(blue and yellow) = P(blue) x P(yellow) = (1/6) x (2/6) = 1/18
Since the marbles are replaced after each draw, the probability of this event is the same for every draw.
The experimental probability of selecting a blue marble followed by a yellow marble after 40 attempts is:
(3/6) x (2/6) x (40 attempts) = 10
Therefore, the experimental probability is 10/40 = 1/4
The percent difference between the theoretical probability and the experimental probability is:
| (experimental probability - theoretical probability) / theoretical probability | x 100%
= | (1/4 - 1/18) / (1/18) | x 100%
= 0.583 x 100%
= 58.3%
Therefore, the percent difference between the theoretical probability and the experimental probability is approximately 58.3%, which is closest to the option 56%.

Step-by-step explanation:
a school chooses 3 randomly selected athletes from each of its sports teams to participate in a survey about athletics at
the school. what type of sample is this?
A.) Simple Random Sample
B.) Stratified Random Sample
C.) Cluster Random Sample
D.) Systematic Random Sample
E.) None of the above
Since the school chooses 3 randomly selected athletes from each of its sports teams, this is a B. Stratified Random Sample.
A stratified random sample refers to a method of sampling which has to do with the division of a population into strata which are smaller groups. This is done in order to make the sampling easier.Stratified Random Sample is different from the Simple Random Sampling where one has to choose from the members. In this case, everyone has an equal chance of being selected.In this case, since the school chooses 3 randomly selected athletes from each of its sports teams, it means the stratified random sample is used.

Consider the quadratic function y = 1/5(x - 2)2 + 5.
Which statements are true about the function and its graph? Select two options.
The vertex of the function is (-2,5).
There are no real roots for the function.
The graph of the function opens down.
The graph contains the point (2,5).
The graph intersects the x-axis at one unique point.
Answer:
Step-by-step explanation:
There are no real roots and the graph contains point (2,5). Notice it is in vertex form. So there must be a point at x = 2 and y = 5. However, if it is the vertex and it opens upwards, that means it cannot intersect the x axis. So 2 and 4 are the correct answers I believe.

St 3 \ep-by-step explanation:
There are some small cubes and some large cubes in a bag.
The cubes are red or the cubes are yellow.
The ratio of the number of small cubes to the number of large cubes is 4:9
The ratio of the number of red cubes to the number of yellow cubes is 3:5
a) What is the least possible number of cubes in the bag?
b) work out the least number of large yellow cubes in the bag.
Answer:
Step-by-step explanation:
Remark
What a wonderful problem. I've never seen one quite like it.
Red to Yellow
The Red to Yellow ratio is given as 3:5
The total number of Red and yellow is something to 8. You get that just by adding the ratio. Let's check it out.
The reds are 3 to 8 and the yellows are 5 to 8.
Does that make sense? 3/8 + 5/8 = 8/8. All the cubes are accounted for.
Small to Large
The given ratio is 4:9
The smalls are 3/13 and the large are 9/13
3/13 + 9/13 equal 13/13 and all the cubes are accounted for.
What is the least possible number that will accomplish this?
8 * 13 is the very least number that will accomplish this. How come?
Because you have two conditions that must be met -- size and color. No other number will work. Any other number will leave a remainder when you put color and size together. So the smallest number you can use is 104,
Last question: Least Number of Large Yellows
The color yellow is 5/8
The size is Large 9/13
So the calculation is
5/8 * 9 / 13 * 104
= 5 * 9
= 45
Notice that the 8 and 13 cancel out. You are left with the number of Yellows and Large =45
Note
I'll leave the other 3 combinations to you. They should add up to 104.
3/8 * 9/13 * 104 = 27
5/8 * 4/13 * 104 = 20
3/8 * 4/13 * 104 = 12
The vertex of this parabola is at (-5, 4). Which of the following could be its
equation?
(-5, 4)
A. y* -(x + 5)2 - 4
B. y = -(x - 5)2 - 4
C. y = -(x - 5)2 + 4
D. y = -(x + 5)2 + 4
Answer:
D
Step-by-step explanation:
Because the x-coordinate of the vertex is negative, only A or D could be the correct equation for this parabola. D is correct because its constant (4) matches the y-coordinate of the vertex (-5, 4).
Answer:
y = -(x + 5)2 + 4

Given equation:
2x + 4 = 0
Find:
The value of x
Computation:
We know that given equation 2x + 4 = 0 is a liner equation with only one variable.
So, we can solve this by elimination method
2x + 4 = 0
Step 1 :
Subtract 4 from both side
2x + 4 - 4 = 0 - 4
2x = -4
Divide 2 from both side
2x / 2 = -4 / 2
x = -2
The value of x = -2
