Lillian is going to invest in an account paying an interest rate of 5.7% compounded continuously. How much would Lillian need to invest, to the nearest ten dollars, for the value of the account to reach $7,600 in 7 years?
Answer:
The amount Lilian needs to invest is $5,160
Step-by-step explanation:
The parameters of the amount Lilian is going to invest in an account are;
The interest rate the account pays = 5.7%
The final amount the investment is expected to reach after the given time period = $7,600
The number of years of the investment = 7 years
The formula for compound interest is presented as follows;
[tex]A = P \cdot \left(1 + \dfrac{r}{n} \right)^{n\cdot t}[/tex]
Where;
A = The final amount = $7,600
P = The amount Lilian is to invest
r = The interest rate = 5.7% = 0.057
n = The number of times the interest is applied per time period = 1
t = The number of period that passes = 7 (years)
Therefore, we get;
[tex]7,600 = P \cdot \left(1 + 0.057 \right)^{7}[/tex]
∴ P = 7,600/(1 + 0.057)⁷ = 5,155.7123754
The amount Lilian needs to invest (rounded to the nearest ten dollars) for the value of the account to reach $7,600 in 7 years, P = $5,160

many did she own before her donation?
Answer: 375
Step-by-step explanation:
Let x equal the number of comic books before her donation.
x × 0.36 = 135
135/0.36 = 375

Answer:
x = 5 or x = -5
Step-by-step explanation:
| a b |
| c d |
det = ad - bc
| x 4 |
| 3 x |
det = x * x - 4 * 3 = x^2 - 12
x^2 - 12 = 13
x^2 = 25
x^2 - 25 = 0
(x + 5)(x - 5) = 0
x = 5 or x = -5

Segment MP is a diameter of circle O.
Circle O is shown. Line segment M P is a diameter. Line segment N O is a radius. Angle N O P is 150 degrees.
Which equation can be used to find mArc M N?
mArc M N – 150 = 360
Answer:
[tex]arc\ MN + 150 = 180[/tex]
Step-by-step explanation:
Given
[tex]\angle NOP = 150^\circ[/tex]
See attachment for circle O
Required
Find [tex]arc\ MN[/tex]
The sum of angles in a semi-circle is 180 degrees.
So:
[tex]arc\ MN + \angle NOP = 180[/tex]
This gives:
[tex]arc\ MN + 150 = 180[/tex]
Hence, the equation is: [tex]arc\ MN + 150 = 180[/tex]

The perimeter of a square patio is (8x - 28). What is the length of one side?
Answer:
Length is 7, Permimeter is 28
Step-by-step explanation:
Perimeter=4×side
(8x-28)=4×x [let length be x]
8x-28=4x
8x-4x=28
4x=28
x=28÷4
x=7
Length = x = 7
Perimeter=(8x-28)
=(7×8)-28
=56-28
=28
Find the area of the figure.
Answer and Step-by-step explanation:
For this shape, we have to draw a line that goes through the point that is inside of the shape from top to bottom.
This creates a square and two triangles.
The area formula for a triangle is A = [tex]\frac{bh}{2}[/tex]
The area of a square is A = b*b
Half of 3 is 1.5.
Triangles (Area combined):
Since there are two triangles that are the same, we only need to find the area of of 1 triangle, and not divide by 2.
A = 3 × 1.5 = 4.5
Square:
A = 3 × 3 = 9
Now, we add them together to get the total area of the figure.
9 + 4.5 = 13.5
The area of the figure is 13.5 [tex]in^{2}[/tex].

Answer:
can you post a pitcure of the question... i cant really understand the words like this.
Step-by-step explanation:
After checking that conditions are met, you perform a significance test of 0:=1 versus :≠1 . You obtain a -value of 0.022.
Which of the following must be true?
A 95% confidence interval for will include the value 0.022.
A 99% confidence interval for will include the value 1.
None of these is necessarily true.
A 99% confidence interval for will include the value 0.022.
A 95% confidence interval for will include the value 1.
Answer:
A
Step-by-step explanation:
The true statement is
A 99% confidence interval for will include the value 1.
What is Confidence Interval?The range of values that we observe in our sample and for which we anticipate finding the value that accurately reflects the population is referred to as a confidence interval.
Given:
[tex]H_0: \mu = 1\\H_\alpha : \mu \neq 1[/tex]
P= 0.022
If the P- value is smaller than significance level, then the null hypothesis is rejected.
P< 0.05 - 5% Reject [tex]H_0[/tex]
P> 0.01 = 1% Fail to Reject [tex]H_0[/tex]
A 95% Confidence interval correspond with a significance test at the 5%
significance level.
A 99% Confidence interval correspond with a significance test at the 1%
significance level.
If the Significance test was Significant then the interval does not contain the value mentioned in the Hypothesis.
95% CI does not contains 1.
99% CI contains 1.

Answer:
4 8.95h + 10 < 115
Step-by-step explanation:
Answer: 4) 8.95h + 10 < 115
Step-by-step explanation:
We know the inequality will be equal to less than 115 since it states that the order was less than $115.
The equation would look like: some amount of shin guards times 8.95 each + $10 shipping = less than $115
8.95h + 10 < 115
(h in the given equation is the amount of shin guards)

The Weston family spends a maximum of
$50.00 per month on entertainment. Write and
graph an inequality to represent this.
Answer:
y < 50x
Step-by-step explanation:
In order to graph this inequality, you first need to identify the important word(s) here to find the inequality sign; in this case, it would be "maximum of $50" a month. Since it's a maximum of $50 a month (or less than $50 a month), you can write it as:
Where m is months and c is total cost, c < 50m
If you need to graph this, you can write it as y < 50x. The cost is y since it's the output, and months is x since that's the input.
