When a principal amount, P, is invested at an annual interest rate, r, and compounded n times per
year, the amount accumulated in the account after t years can be found with the equation:
A = P(1 + r/n) ^nt
Javier invested $2,350 in a savings account for 5 years with a rate of 1.75% compounded every six
months. In this situation, what is n?
0.0175
5 6 2
Answer:
n =2
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
In this question:
The money is compounded every 6 months.
n is the number of times that interest is compounded per year.
Each 6 months means 12/6 = twice a year. So n =2..
What expression is equivalent to 2(t-4)+1
Answer:2t-7
i just kinda solved it hehe
The (2t - 7) is the expression that is equivalent to (2(t-4)+1) and this can be determined by using the arithmetic operations.
Given :
Expression - 2(t - 4) + 1
The following steps can be used to evaluate the given expression:
Step 1 - Open the parenthesis in the given expression. Then multiply 2 by t and then multiply 2 by -4.
= 2t - 8 + 1
Step 2 - Now, subtract 8 from 1 in the above expression.
= 2t - 7
So, the (2t - 7) is the expression that is equivalent to (2(t-4)+1).

Answer:
The new median would be 15.
Step-by-step explanation:
This is because the median means the middle number so we can cross out 2 and 25. Then cross out 6 and 23. Then cross out 7 and 21. Next, cross out 14 and 20. Since there is only one number left, 15, that number is therefore the median.
Answer:
List the numbers in order including 25
2,6,7,14,15,20,21,23,25
choose the number in the middle
15 has 4 numbers to the left and right so it is in the middle so it is the median

A tile is chosen at random from a bag containing the following tiles: 7 blue, 3 green, 6 yellow, and 4 purple. Let P be the probability distribution defined on the set {blue, green, yellow, purple}. Write each probability
Answer:
P of b=7/20
P of g=3/20
P of y=6/20=3/10
P of p=4/20=1/5.
Step-by-step explanation:
there are in total 20 tiles so S=20
there are 7 blue tiles so P=E/S=7/20
there are 3 green tiles so P=E/S=3/20
there are 6 yellow tiles so P=E/S=6/20=3/10.
there are 4 purple tiles so P=E/S=4/20=1/5
What is the area of the shape below
Answer:
The area of the shape is [tex]A=886 \:cm^2[/tex].
Step-by-step explanation:
The shape in the graph is a composite figure is made up of several simple geometric figures such as triangles, and rectangles.
Area is the space inside of a two-dimensional shape. We can also think of area as the amount of space a shape covers.
To calculate the area of a composite shape you must divide the shape into rectangles, triangles or other shapes you can find the area of and then add the areas back together.
First separate the composite shape into three simpler shapes, in this case two rectangles and a triangle. Then find the area of each figure.
To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.
The area of the first rectangle is [tex]A=34\cdot 16=544\:cm^2[/tex]
The area of the second rectangle is [tex]A=11\cdot19=209\: cm^2[/tex]
The area of a triangle is given by the formula [tex]A=\frac{1}{2} bh[/tex] where b is the base and h is the height of the triangle.
The area of the triangle is [tex]A=\frac{1}{2} \cdot 14\cdot19=133\:cm^2[/tex]
Finally, add the areas of the simpler figures together to find the total area of the composite figure.
[tex]A_{composite\:shape}=544+209+133=886 \:cm^2[/tex]

Patel made a deposit into an account that earns 5%simple interest. After 10 years Patel had earned $1500 in interest. How much was Patel’s initial deposit?
Answer:
Patel’s initial deposit was $3000
Step-by-step explanation:
Given:
Simple interest (S.I.) = 5%
Time period (t) = 10 years
Interest earned (r) = $1500
To find: Patel’s initial deposit
Solution:
Simple interest is a method of calculating the interest charged on the principal, or original amount of a loan.
Let p denotes original amount of a loan
[tex]S.I.=\frac{p\times r\times t}{100}\\\Rightarrow 1500=\frac{p\times 5\times 10}{100}\\\Rightarrow p=\frac{1500\times 100}{5\times 10}\\=3000[/tex]
So, Patel’s initial deposit was $3000

-9x+7y=28 find the y intercept
In slope-intercept form, we have these values (y = mx + b):
m = slope
b = y-intercept
Change the equation from standard form to slope-intercept form.
-9x + 7y = 28
-9x + 9x + 7y = 28 + 9x
7y = 28 + 9x
7y/7 = 28/7 + 9x/7
y = 4 + 9/7x
y = 9/7x + 4
Therefore, the y-intercept is 4.

In a clothing store, 55% of the customers buy a shirt, 25% of the customers
buy a pair of pants, and 20% of the customers buy both a shirt and a pair of
pants.
If a customer is chosen at random, what is the probability that he or she buys
a shirt or a pair of pants?
A. 0.225
B. 0.60
C. 0.30
D. 0.80
Answer:
s= the customer buy a shirt
p= the customer buy pants
[tex] p(s) = 0.55, p(p) = 0.25 , p(s \cap p) =0.20[/tex]
And we want to find this probability:
[tex] p(s \cup p) [/tex]
And we can use the definition of total probability and we have:
[tex] p(s \cup p) = p(s) +p(p) -p(s \cap p)[/tex]
And replacing we got:
[tex] p(s \cup p) = 0.55+0.25 -0.20 = 0.60[/tex]
And the best answer for this case is:
B. 0.60
Step-by-step explanation:
For this case we can define the following events:
s= the customer buy a shirt
p= the customer buy pants
And we have the following probabilities given:
[tex] p(s) = 0.55, p(p) = 0.25 , p(s \cap p) =0.20[/tex]
And we want to find this probability:
[tex] p(s \cup p) [/tex]
And we can use the definition of total probability and we have:
[tex] p(s \cup p) = p(s) +p(p) -p(s \cap p)[/tex]
And replacing we got:
[tex] p(s \cup p) = 0.55+0.25 -0.20 = 0.60[/tex]
And the best answer for this case is:
B. 0.60

formulate the quadratic function that contains the points (-2,1),(0,1)and (1,4)
Answer:
y = x^2 +2x +1
Step-by-step explanation:
Let's see how this works.
Two of the given points have the same y-value, so the axis of symmetry is located halfway between. If we translate the desired curve down 1 unit, those symmetrical values become zeros, and our function will look like ...
f(x) = ax(x +2)
We want this to go through the third point, also translated down by 1 unit, so we have ...
3 = a(1)(1+2) = 3a
That is, a=1, so f(x) = x(x+2) and translating that up 1 unit gives our desired function:
y = x(x+2) +1
y = x^2 +2x +1
_____
Using the quadratic regression function of a graphing calculator gives the same result.

Comment on the solution approach
For arbitrary points, one would generally substitute them into the formula for the function you want:
y = ax^2 +bx +c
to get three equations in the parameters a, b, and c. These equations would be solved to find the desired coefficients. As noted elsewhere, one of the given points for this problem is the y-intercept (0, 1), so right away we know c = 1. ("c" is the y-intercept.)
That leaves two remaining equations in two unknowns (using the other two points).
Using the point (-2, 1), the equation is ...
1 = a(-2)^2 +b(-2) +1 ⇒ 4a - 2b = 0 ⇒ 2a -b = 0
Using the point (1, 4), the equation is ...
4 = a(1^2) +b(1) +1 ⇒ a +b = 3
Adding these gives 3a = 3, or a=1. Then substitution gives b=2, so the final equation is ...
y = x^2 +2x +1
