Answer:
$1,349.8
Step-by-step explanation:
Using the formula given:
A=Pe^rt, where
A= ending amount
P= beginning amount
e= Euler’s number that is approximately 2.718
r= rate: 3%=0.03
t= time: 10 years
A= $1,000*(e^0.03*10)
A= $1,000*(e^0.3)
A= $1,349.8
According to this, the answer is that the balance after 10 years is $1,349.8.
What is the equation for the blue line?
Answer:
f(x) = -1/2x + 2
Step-by-step explanation:
f(x) = ax + b
x = 0 , y = 2
y = 0 , x = 4
[tex]a = \frac{y'' - y'}{x'' - x'}\\a= \frac{2 - 0}{0 - 4} \\a= \frac{2}{-4} = \frac{-1}{2}[/tex]
[tex]0 = \frac{-1}{2} . 4 + b\\0 = -2 + b\\b = 2[/tex]

given the graph function below which of the following ordered pairs are found on the inverse function
Answer:
Option A.
Step-by-step explanation:
Graph of function has been given in the figure.
Coordinates of the points lying on this graph will be
x -2 -1 0 1 2
y -10 -3 -2 -1 6
Therefore, coordinates of the points which will lie on the inverse of this function will be
x -10 -3 -2 -1 6
y -2 -1 0 1 2
Therefore, Option A. will be the answer.
Researchers are interested in determining whether more women than men prefer the beach to the mountains. In a random sample of 200 women, 45% prefer the beach, whereas in a random sample of 300 men, 52% prefer the beach. What is the 99% confidence interval estimate for the difference between the percentages of women and men who prefer the beach over the mountains?
Answer:
The 99% confidence interval estimate for the difference between the percentage of women and men who prefer the beach over the mountains is -18.72% < (p₁ - p₂) < 4.72%
Step-by-step explanation:
The given parameters are;
Sample size of the women sample, n₁ = 200
Percentage of the women that prefer beach, p₁ = 45%, [tex]\hat p_1[/tex] = 0.45
Sample size of the men sample n₂ = 300
Percentage of the men that prefer beach, p₂ = 52%, [tex]\hat p_2[/tex] = 0.52
Confidence level of the confidence interval = 99%
α = 1 - 0.99 = 0.01, therefore, α/2 = 0.005
The equation for the confidence interval for the difference between two proportions is given as follows;
[tex]\left (\hat{p}_{1} - \hat{p}_{2} \right )\pm z_{\alpha /2}\sqrt{\dfrac{\hat{p}_{1}(1-\hat{p}_{1})}{n_{1}}+\dfrac{\hat{p}_{2}(1-\hat{p}_{2})}{n_{2}}}[/tex]
[tex]z_{\alpha /2}[/tex] = ±2.57 from the z score tables
Plugging in the vales, we have;
[tex]\left (0.45 - 0.52 \right )\pm 2.57\sqrt{\dfrac{0.45(1-0.45)}{200}+\dfrac{0.52(1-0.52)}{300}}[/tex]
Which gives;
-0.1872 < [tex](\hat p_1 - \hat p_2)[/tex] < 0.0472
The 99% confidence interval estimate for the difference between the percentage of women and men who prefer the beach over the mountains = -18.72% < (p₁ - p₂) < 4.72%.

An arithmetic sequence is a sequence where the difference between each consecutive term is the same.
The nth term of an arithmetic series is given as:
a(n) = a(1) + (n - 1)d
The 64th term of the arithmetic sequence is 596.
What is an arithmetic sequence?It is a sequence where the difference between each consecutive term is the same.
Example:
2, 4, 6, 8, 10 is an arithmetic sequence.
common difference = 2
The first term = 2.
We have,
29, 38, 47,.....
First term = 29
a(1) = 29
Common difference:
= 38 - 29
= 9
Now,
The nth term of an arithmetic series is given as:
a(n) = a(1) + (n - 1)d
The value of the 64th term in the arithmetic sequence.
a(64) = a(1) + (64 - ) x 9
a(64) = 29 + 63 x 9
a(64) = 29 + 567
a(64) = 596
Thus,
The 64th term of the arithmetic sequence is 596.

What is the value of 1 over 2 x+3.4y when x=3 and y = 4?
Answer:
The value of the given expression is 27.1
Step-by-step explanation:
We are given an expression of two variable x and y.
We need to find the value of expression at x = 3 and y = 4
So first put x = 3 and y = 4 into expression and simplify
1/2 x 3 (3) + 3.4 x 4
➡️ 1/2 x 27 + 13.6
➡️ 27/2 + 13.6
➡️ 13.5 + 13.6
Now, add both of the numbers together. ( as an addition problem)
Therefore, when you ad the 2 together, you get the total of 27.1

at which value(s) of x does the graph of the function f(x) have a vertical asymptote?
Answer:
E. x = 4
F. x = -2
Step-by-step explanation:
Asymptotes occur when you have an undefined (a divide by 0 error). So x in the denominator can't equal zero. The 2 values that make the denominator zero are 4 and -2.
A rectangular piece of metal is 25in longer than it is wide . Squares with sides 5in long are cut from the four corners and the flaps are folded upward to form an open box. If the volume of the box is 750in, what were the original dimensions of the piece of metal
Answer:
Step-by-step explanation:
Let width be x
Let lenght be 25 + x
Total ax = (25+x) * x
Square with 5in long are cut from the four corner formed = 750in
(25+x-10) * (x-10) * 5 = 750
(15+x) (x-10) = 150
15x-150+x^2-10x =150
15x -150-150+x^2-10x+0
x^2+15x-300=0
(ax^2+bx+c=0)
Harpreet took out a payday loan of $500.00. He had to repay $540.00 within 7 days.
A) What was the daily interest on the loan
B) What was the annual interest?
Answer:
a) 1,14%
b) 317%
Step-by-step explanation
J = C . i . t
540 - 500 = 500 . i . 7
40 = 500 . 7 . i
i = 0,0114 = 1,14% within day
-------------------------------------------
J = 500 . 0,0114 . 365 = 2085,71
2085,71 - 500 = 500 . i . 1
1585,71 = 500 . i
i = 3,17 = 317% annual

You roll a 6-sided die two times.
What is the probability of rolling an odd number and then rolling a 3?
Simplify your answer and write it as a fraction or whole number.
Answer:
The probability of rolling a 3 is 1/6 as there is only one face labeled "3" out of 6 total.
Multiplying the two probabilities gives (1/2)*(1/6) = (1*1)/(2*6) = 1/12 (Correct Answer)
The two events are independent from one another.
Starting with $5,000, you invest in an account that pays 2% APR, compounded quarterly, and plan to leave the money there and not touch it for at least 12 years. How much MORE money would you have after 12 years if the interest had been compounded continuously instead? Round to the nearest cent.

If Jodi eats 2 chocolates she will consume 72 calories how many calories will she consume if she eats 5 chocolates
Answer:
x = 180
Step-by-step explanation:
We can use ratios to solve
2 chocolates 5 chocolates
--------------------- = ------------------
72 calories x calories
Using cross products
2 *x = 5*72
2x = 360
Divide each side by 2
2x/2 = 360/2
x = 180
Set up a ratio 2/72 = 5/x.
Now use cross-products.
(2)(x) = (5)(72).
2x = 360.
Now divide both sides by 2.
This gives us x = 180.
So, Jodi consumes 180 chocolates when she eats 5 chocolates.

-(x+7)/6
Step-by-step explanation:
y = -6x-7
Exchange x and y
x= - 6y-7
Solve for y
Add 7 to each side
x+7 = -6y-7+7
x+7 = -6y
Divide by -6
(x+7) / -6 = -6y/-6
(x+7)/ -6 = y

f(n) = -11 + 22(n = 1)
Complete the recursive formula of f(n).
f(1) =
f(n) = f(n - 1)+
Answer:
[tex]f(n)=f(n-1)+22[/tex].
Step-by-step explanation:
Note: In the given function it should be (n-1) instead of (n=1).
Consider the given function is
[tex]f(n)=-11+22(n-1)[/tex]
It is the explicit form of an A.P.
For [tex]n=1[/tex],
[tex]f(1)=-11+22(1-1)=-11+0=-11[/tex]
For [tex]n=2[/tex],
[tex]f(2)=-11+22(2-1)=-11+22=11[/tex]
Common difference is
[tex]d=a_2-a_1=11-(-11)=11+11=22[/tex]
The recursive formula of an A.P. is
[tex]f(n)=f(n-1)+d[/tex]
Substitute [tex]d=22[/tex] in the above formula.
[tex]f(n)=f(n-1)+(22)[/tex]
[tex]f(n)=f(n-1)+22[/tex]
Therefore, required recursive formula is [tex]f(n)=f(n-1)+22[/tex].
A recipe for stew calls for 2 1/2 pounds of meat, 22 ounces of beans, 14 ounces of carrots, and 2 pounds 6 ounces of potatoes. Which is the weight of the ingredients in the stew in pounds?
Answer:
7.125pounds
Step-by-step explanation:
if a recipe for stew calls for 2 1/2 pounds of meat, 22 ounces of beans, 14 ounces of carrots, and 2 pounds 6 ounces of potatoes, in order to get the weight of the ingredients in the stew in pounds, we will convert all the units to pounds first and then add them together.
On conversion;
since 1 ounce = 0.0625pounds
Weight of beans in pounds = 22 * 0.0625 = 1.375pounds
Weight of meats = 2 1/2 pounds
Weight of carrots in pounds = 14*0.0625 = 0.875pounds
Weight of potatoes in pounds = 2+(6*0.0625) = 2+0.375 = 2.375pounds
weight of the ingredients in the stew in pounds = 1.375+2.5+0.875+2.375
weight of the ingredients in the stew in pounds = 7.125pounds
