Answer:
$176420
Step-by-step explanation:
Monthly payment = $992
Yearly payment = 992 × 12 = $11064
Total payment = 11064 × 30 = $331920
Interest = 331920 - 155500 = $176420. The interest seems too much, are you sure there's no mistake in the question? Maybe the monthly payment is more than what you've written here?

In 1949, Jackie Robinson hit .342 for the Brooklyn Dodgers; in 1973, Rod Carew hit .350 for the Minnesota Twins. In the 1970s the mean batting average was
.261 and the standard deviation was .0317. Determine which
batting average was more impressive.
In 1973, the batting average of .350 of Rod Carew is more impressive as it has a higher z-score of 2.81
To establish which batting average was more spectacular, we must compare it to the mean and standard deviation of 1970s hitting averages. The case of Jackie Robinson,
z = (x - μ) / σ
z = (.342 - .261) / .0317
z = 2.56
For Rod Carew,
z = (x - μ) / σ
z = (.350 - .261) / .0317
z = 2.81
A higher z-score indicates a more impressive performance relative to the mean. As a result, Rod Carew's .350 batting average was more spectacular, as it had a higher z-score of 2.81 than Jackie Robinson's z-score of 2.56.

The triangle has one solution. The remaining side c ≈ 4 and remaining angles B = 30°; C = 31°.
Option D is correct.
How to solveif angle A is obtuse and if a > b then the triangle has one solution
We are given ∠ = 119° which is obtuse and side a= 7 and side b - 4 i.e 7>4 so, the triangle has one solution.
Finding remaining sides c and ∠B and ∠C
Using the Law of sines to find ∠B
a/sin A = b/sin B
7/sin 119° = 4/sin B
7 * sin B = 4 * sin 119
7*sin B = 4(0.874)
sin B = 3.496/7
B = sin^-1(0.4994)
B = 29.96 = 30°
We know that sum of angles of triangle = 180°
So, 180° = 119° + 30° +∠C
180° = 149° + ∠C
=> ∠C = 180° - 149°
∠C = 31°
Now finding c
b/sin B = c /sin C
4/Sin 30 = c/sin 31
4* sin 31 = c*sin 30
4*0.515 = c* 0.5
=> c = 4*0.515/0.5
c = 4.12 ≈ 4
So, Option D one solution; c ≈ 4; B = 30°; C = 31° is correct.

Which statement concerning the equation x² - 1 = x is true?
1. Its discriminant is 0, so it has no solution.
2. Its discriminant is 5, so it has two real solutions.
3. Its discriminant is 0, so it has one real solution.
4. Its discriminant is -3, so it has two complex solutions.
Answer:
The equation x² - 1 = x can be rewritten as x² - x - 1 = 0. We can use the quadratic formula to find the solutions:
x = (-b ± sqrt(b² - 4ac)) / 2a
In this case, a = 1, b = -1, and c = -1. So:
x = (1 ± sqrt(1 - 4(1)(-1))) / 2(1)
x = (1 ± sqrt(5)) / 2
Therefore, the equation has two real solutions, and the discriminant is positive. The answer is 2. Its discriminant is 5, so it has two real solutions.

Directions - Answer the questions based on the following scenario and graph.
Jim and Cassie are both saving money each week in order to buy an awesome Bulls snapback hat (and leave the price stickers on it, of course). The hat costs $27.
Jim's rate of savings (slope): 3
Cassie's rate of savings (slope): 3
Jim's y intercept: 3
Cassie's y intercept: 12
Jim's Savings Equation: y = 3x + 3
Cassie's Savings Equation: y = 3x + 12
Number of weeks it will take to Cassie to save $27: 5
Number of weeks it will take to Jim to save $27: 8
Yes, Jim and Cassie's rates parallel.
Cassie will be able to buy the hat first.
We know that the slope intercept form of a straight line is,
y = mx + c, where m is the slope of the line and c is the y intercept.
For the straight line for Cassie:
The line passing through the points (0, 12) and (1, 15).
So the slope = (15 - 12)/(1 - 0) = 3
The y intercept is = 12.
Equation of the straight line is: y = 3x + 12 ....... (i), where y represents earning in dollars and x represents the time in weeks.
For the straight line for Jim:
The line passing through the points (0, 3) and (1, 6).
So the slope = (6 - 3)/(1 - 0) = 3
The y intercept is = 3
Equation of the straight line is: y = 3x + 3 .......... (ii), where y represents earning in dollars and x represents the time in weeks.
Since the slope of both are equal so the rates of both are parallel.
Substituting the value y = 27 in equation (i) and (ii) we get,
equation (i): 3x + 12 =27
3x = 27 - 12
3x = 15
x = 15/3
x = 5
So Cassie needs 5 weeks to save $27.
Equation (ii): 3x + 3 = 27
3x = 27 - 3
3x = 24
x = 24/3
x = 8
So Jim needs 8 weeks to save $27.
Hence Cassie will be able to buy the hat first.

What is equation?An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides, left-hand side (LHS) and right-hand side (RHS), connected by an equal sign (=). The LHS and RHS can contain numbers, variables, operators, and functions, and the equal sign indicates that the value of the expression on the LHS is equal to the value of the expression on the RHS.
Here,
Since there are 100 centimeters in one meter, we can convert meters to centimeters by multiplying the length in meters by 100.
So, to convert 40 meters to centimeters, we can multiply 40 by 100:
40 meters = 40 x 100

The area of a rectangular shaped rug is 81 square feet. If the rug is 9 ft long, what is ire perimeter?
The perimeter of the rug is 36ft
What is perimeter?Perimeter is the total length around the outside of a shape. The perimeter can be found by adding all the sides of the shape.
Perimeter of a rectangle is expressed as ;
P = 2(l+w)
The area of the rug is 81ft²
area = l× w
length = 9ft
width of the rug = 81/9 = 9ft
Therefore the perimeter of the rug will be
P = 2(l+w)
P= 2( 9+ 9)
P = 2 × 18

Use the estimated angle to find the distance of the life-raft from the lighthouse.
The correct angle of elevation for the lighthouse's top is roughly 1.91°.
How to find the distance of the lift-raft from the lighthouse?Consider the diagram drawn below, P is the position of the person in the lift-raft, B is the base of the lighthouse and the T is top of the lighthouse.
The diagram shows that the angle produced between the person in the life raft's line of sight to the top of the lighthouse and the horizontal is equal to the angle formed by the top of the lighthouse's height. Call this angle "[tex]\alpha[/tex]".
a) The distance "d" between the life raft and the lighthouse can be calculated using trigonometry.
[tex]tan\alpha = \frac{opposite}{adjacent} \\tan\alpha = \frac{20}{d}[/tex]
putting the value of [tex]\alpha[/tex] = 3 degrees put into the above equation.
[tex]tan3 = \frac{20}{d}[/tex]
[tex]d = \frac{20}{tan3}[/tex]
d = 354.14 (rounded to 2 decimal points
The life raft is therefore roughly 354.14 meters away from the lighthouse.
b)
Let's now calculate the proper angle of elevation for the situation when the life raft is 600 meters from the lighthouse.
[tex]tan\alpha = \frac{opposite}{adjacent}\\ tan\alpha = \frac{20}{600}[/tex]
solving for [tex]\alpha[/tex] we get,
[tex]\alpha = tan^{-1} (\frac{20}{100})\\\alpha = 1.91 degree\\[/tex]

A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 169 cm and a standard deviation of 2.2 cm. For shipment, 10 steel rods are bundled together.
Answer the following rounding to three decimals where appropriate.
Find the probability that the average length of a randomly selected bundle of steel rods is greater than 168.58 cm.
P(M > 168.58) = ???
The probability that the average length of a randomly selected bundle of steel rods is greater than 168.58 cm is 0.7486
How to calculate the probabilityFirst, we need to calculate the z-score for the sample mean:
z = (x - μ) / (σ / √n)
z = (168.58 - 169) / (2.2 / √10)
z = -0.67
Next, we need to find the probability that a randomly selected bundle of steel rods will have a mean length greater than 168.58 cm. This is equivalent to finding the area under the standard normal distribution curve to the right of z = -0.67.
Using a standard normal distribution table or calculator, we find that the probability is 0.7486.
