Alex borrowed $3500 from two banks. One bank charged a simple interest of 8% and another bank
charged a simple interest of 12%. If he paid a total interest of $332 for one year, find the amount that he
borrowed from each bank.
Answer:
$ 2,200 for 8%, $ 1,300 for 12%
Step-by-step explanation:
I=PRT
Let Bank 1 be x
332= x (8%) + (3,500-x) 12%
332= x (0.08) + (3,500-x) 0.12 change the percent to decimal
332= 0.08x + 420 - 0.12x
0.04x= 420-332
x= [tex]\frac{88}{0.04}[/tex]
x= 2,200 (Bank 1)
Bank 2= 3,500-Bank 1
Bank 2= 3,500- 2,200
Bank 2= 1,300

Answer:

Step-by-step explanation:
volume = L x W x H
A. 4 x 7 x 8 = 224
B. 8 x 5 x 6 = 240
then you compare the number and see which one is greater
To find volume of a box you use the equation V= L*W*H
Box A-8*7*4= 224 in^3
Box B-6*5*8=240 in^3
Box b has a larger volume
Can you guys help me and answer this math question below
Answer:
point D
Step-by-step explanation:
4 would be the x axis so look horizontal, 5 is on y axis (y to the sky) so look vertically for 5
Answer: Point D
===============================================================
Explanation:
We start at the lower left corner, which is the location (0,0)
Then we move to the right four spaces to arrive at (4,0) which is where point L is at right now.
Lastly, we move 5 units up to get to (4,5) which is where point D is located.
Each (x,y) point can be thought of as an address so we can quickly communicate a point's location to someone, even if they don't have the visual in front of them. You can think of it like latitude and longitude. The game of battleship uses a similar concept, but it uses letters as the first coordinate.

In parts (a)−(d) below, either use the information given to determine the distribution of the random variable, or show that the information given is not sufficient by describing at least two different random variables that satisfy the given condition. (a) X is a random variable such that MX(t) = e 6t 2 when |t| < 2. (b) Y is a random variable such that MY (t) = 2 2−t for t < 0.5. (c) Z is a random variable such that MZ(t) = [infinity] for t ≥ 5. (d) W is a random variable such that MW (2)
Answer:
a.) X ≈ N (0, 12)
b.) Y ≈ exp(2)
c.) The given distribution is not defined.
d.) Not a standard form of any distribution .
Step-by-step explanation:
Given - In parts (a)−(d) below, either use the information given to determine
the distribution of the random variable, or show that the information
given is not sufficient by describing at least two different random
variables that satisfy the given condition.
To find - (a) X is a random variable such that Mₓ(t) = [tex]e^{6t^{2} }[/tex] when |t| < 2.
(b) Y is a random variable such that [tex]M_{Y}[/tex](t) = [tex]\frac{2}{2 - t}[/tex] for t < 0.5.
(c) Z is a random variable such that [tex]M_{Z}[/tex](t) = ∞ for t ≥ 5.
(d) W is a random variable such that [tex]M_{W}[/tex](2) = 2
Proof -
a.)
As we know that the moment generating function of normal distribution is given by
Mₓ(t) = [tex]e^{ut + \frac{1}{2}t^{2} \sigma^{2}}[/tex]
Now,
Mₓ(t) = [tex]e^{6t^{2} }[/tex]
= [tex]e^{0(t) + \frac{12}{2} t^{2} }[/tex]
⇒μ = 0, σ = 12
Nd it is represented by
X ≈ N (0, 12)
b.)
Moment generating function of exponential function is given by
[tex]M_{Y}[/tex](t) = [tex]( 1 - \frac{t}{\theta})^{-1}[/tex]
Now,
[tex]M_{Y}[/tex](t) = [tex]\frac{2}{2 - t}[/tex] for t < 0.5.
= [tex]\frac{1}{\frac{2 - t}{2} }[/tex]
= [tex]\frac{1}{1 - \frac{t}{2} }[/tex]
= [tex]( 1 - \frac{t}{2} )^{-1}[/tex]
And it is represented by
Y ≈ exp(2)
c.)
Z is a random variable such that [tex]M_{Z}[/tex](t) = ∞ for t ≥ 5.
The given distribution is undefined.
d.)
[tex]M_{W}[/tex](2) = E([tex]e^{2w}[/tex] )
= [tex]\int\limits^{-\infty}_{\infty} {e^{2w} f(w) } \, dw[/tex]
= 2
It is not the standard form of any distribution.
A 95% confidence interval for the proportion of American adults who believe that regular exercise is important was computed to be [0.726, 0.780]. Given this confidence interval, which of the following values are reasonable estimates for the proportion of all American adults who believe that regular exercise is important (i.e., the population proportion).
a. 0.730
b. 0.765
c. 0.770
d. 0.795
Using confidence interval concepts, it is found that the reasonable estimate for the proportion of all American adults who believe that regular exercise is important is of 0.753.
What is a confidence interval?
It is the range in which a parameter is expected to be given a confidence level, has format (a,b), and the point estimate of the parameter is the mean between a and b.
In this problem, the interval is [0.726, 0.780], hence, the estimate is of:
(0.726 + 0.78)/2 = 0.753

Find the value of csc Θ if cos Θ = - 3/5 180° ≤ Θ < 270°
csc =
Answer:
csc Θ = - 5/4
Step-by-step explanation:
Consider a coordinate plane. As the range is from 180 to 270, we find that the triangle to be created should be in the 3rd quadrant.
cos Θ = - 3/5
5 ---> hypotenuse
- 3 --> adjacent side
Θ = angle is between the respective sides
We have to find the length of the remaining side, which would be the following:
- √5^2 - (-3)^2 = - √25 - 9
= - √16
= - 4
Remember csc Θ = Hypotenuse/Opposite = 5/-4 = - 5/4

Mel paid $15.75 for 6 greeting
cards. Some of the cards cost
$2.50 each, and some cost $3.25
each. Let x represent the number
of cards that cost $2.50 each,
and y represent the number of
cards that cost $3.25 each. This
situation can be represented by
the system x + y = 6 and
2.5x + 3.25y = 15.75. How many
of each type of card did Mei
purchase?
Answer:
Step-by-step explanation:
x + y = 6 -------------(I)
y = 6 -x
2.5x + 3.25y = 15.75 -------------(II)
substitute y = 6 - x in equation (II)
2.5x + 3.25*(6 - x) = 15.75 {Distributive property: a(b +c) =a*b + b*c}
2.5x + 3.25*6 - x * 3.25 = 15.75
2.5x + 19.5 - 3.25x = 15.75
2.5x - 3.25x + 19.5 = 15.75 {Combine like terms}
-0.75x + 19.5 = 15.75
-0.75x=15.75 - 19.5
-0.75x = -3.75
x = -3.75/-0.75
x = 5
Plugin x = 5 in (I)
5 + y = 6
y = 6 - 5
y = 1

Tessa made 14 out of 22 free throw attempts in the first half of practice and 22 out of 28 attempts in the second half of practice. What is her free throw average for the whole practice, written as a decimal? PLEASE HELP, I NEED IT QUICK!! 30 POINTS FOR IT
Answer:
0.71
Step-by-step explanation:
1st attempt = [tex]\frac{14}{22} = 63%[/tex]%
2nd attempt = [tex]\frac{22}{28} = 79%[/tex]%
To get the average of something, find the sum of the numbers and then divided the sum by the total number of values there are.
⇒ 63 + 79 = 142
⇒ 142 / 2 = 71%
⇒ 71% = .71
