A specific type of financial instrument pays 15% simple interest (based on the purchase value) and lasts for 1.5 years. The instrument can be bought at any price. An investor purchases the instrument for P0, and has calculated that the total value of the investment (i.e. P0 plus interest earned) will be $4,000 at maturity.
Answer:
Correct answers:
$3265$
For this, we can use the formula
A=P0(1+rt).
We know that A=$4,000,r=15%=0.15 and t=1.5, so we can rearrange the formula for A to give
P0=A1+rt,
and substituting the known quantities gives
P0=$4,0001+0.15×1.5=$4,0001.225=$3,265.30..,
which is $3,265 to the nearest dollar.

An engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such that it would produce a mean pressure of 5.9 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 160 engines and the mean pressure was 6.0 pounds/square inch. Assume the variance is known to be 0.36. A level of significance of 0.05 will be used. Determine the decision rule.
Answer:
Calculated value Z = 2.1097 > 1.96 at 0.05 level of significance
There is a difference between the means
Step-by-step explanation:
Step(i):-
Given that mean of the Population = 5.9pounds/square inch
Given mean of the sample = 6.0pounds/square inch
Given that variance of the Population = 0.36
The standard deviation of the Population = √0.36 =0.6
critical value (Z₀.₀₅)= 1.96
Step(ii):-
Null Hypothesis:H₀: x⁻ = μ
Alternative Hypothesis:H₁: x⁻ ≠ μ
Test statistic
[tex]Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }[/tex]
[tex]Z = \frac{6.0-5.9 }{\frac{0.6}{\sqrt{160} } }[/tex]
Z = 2.1097
Final answer:-
Calculated value Z = 2.1097 > 1.96 at 0.05 level of significance
The null hypothesis is rejected
There is a difference between the means

Select all angles that have a cosine of 9/15
Answer:
Step-by-step explanation:
All the angles that have a cosine of 9/15 are,
⇒ ∠P and ∠X
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
Triangle PQR is similar to triangle XYZ.
Hence, We get;
In triangle PQR,
cos P = 9/15
And, In triangle XYZ,
cos X = XZ / ZY
cos X = 9 / 15
Thus, All the angles that have a cosine of 9/15 are,
⇒ ∠P and ∠X

SIMPLIFY IT PHOTO IS UP I WILL MARK IT BRAINLIEST
Step-by-step explanation:
Notice that
9y² - 4xy + 4x²/9 = (3y - 2x/3)².
Therefore (9y² - 4xy + 4x²/9) / (3y - 2x/3)
= (3y - 2x/3).
Answer:
(9y²-4xy+4x²/9)/(3y-2x/3)
={(3y)²-2(3y)(2x/3)+(2x/3)²}/(3y-2x/3)
=(3y-2x/3)²/(3y-2x/3)
=(3y-2x/3)

How to solve system of two equations:
First of all, we should get one variable in terms of other variable in one equation and substitute this variable in another equation. And solving that we get two variables value.
If you have two different equations with the same two unknowns in each, you can solve for both unknowns. There are three common methods for solving: addition/subtraction, substitution, and graphing.
Here,
let's consider price of hot dogs = x and price of hamburgers = y
then, 164x + 74y = $706 --- ( 1 )
and 256x + 61y = $884 --- ( 2 )
Now, from eq - 1 we get x = ($706 - 74y) / 164
Substitute this x value in eq - 2,
256($706 - 74y)/164 + 61y = $884
=> $706*256 - 74y*256 + 61y*164 = $884 * 164
=> 180,736-8940y = 144,976
=> 180,736 - 144,976 = 8940y
=> 35,760/8940 = y
=> y = $4.
By substituting in eq - (1) we get x = $2.5
So, The price of hot dog = $2.5

Need help with this khan academy question. Plus minus square root of negative nine equals plus or minus
Answer:
3i
Step-by-step explanation:
3i x 3i = -9
-3i x -3i = -9
Therefore the square root of -9 is 3i or -3i
The simplified radical expression ±√(-9) is ±3i
The expression ±√(-9) involves finding the square root of a negative number. In the real number system, this is not possible, as no real number multiplied by itself will result in a negative value. To overcome this limitation, mathematicians introduced the concept of imaginary numbers. The imaginary unit, denoted by 'i,' is defined as √(-1).
Now, let's simplify the expression ±√(-9) step by step:
Step 1: Begin by recognizing that √(-9) is the square root of -9.
Step 2: Since √(-1) is 'i,' we can rewrite √(-9) as √(9) * √(-1).
Step 3: The square root of 9 (√9) is 3.
Step 4: Replace √(-1) with 'i.'
Step 5: The final result is 3i.
Therefore, the simplified form of ±√(-9) is ±3i.

The number of visits to public libraries increased from 1.3 billion in 1998 to 1.5 billion in 2002. Find the average rate of change in the number of public library visits from 1998 to 2002.
Answer: The average rate of change in the number of public library visits from 1998 to 2002 = 0.05 billion per year.
Step-by-step explanation:
Given: Number of visits in 1998 = 1.3 billion
Number of visits in 2002 = 1.5 billion
The average rate of change in the number of public library visits from 1998 to 2002 = [tex]\dfrac{\text{Number of visits in 2002 - Number of visits in 1998}}{2002-1998}[/tex]
[tex]=\dfrac{1.5-1.3}{4}\\\\=\dfrac{0.2}{4}\\\\= 0.05 \text{ billion per year.}[/tex]
Hence, the average rate of change in the number of public library visits from 1998 to 2002 = 0.05 billion per year.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The measure of the exterior angle is given as,
Exterior angle = 180° - Interior angle
Exterior angle = 180° - 156°
Exterior angle = 24°
The total number of sides of the polygon will be given as,
Exterior angle = 360° / (Number of sides)
24° = 360° / n
n = 360° / 24°
n = 15
