A thermometer comes with a guarantee that the stated temperature differs from the actual temperature by no more than 1.5 degrees Fahrenheit. Write an equation to represent the minimum and maximum actual temperatures when the thermometer states that the temperature is 87.4 degrees Fahrenheit.
Answers
Answer:
The equation is;
T = 87.4 ± 1.5
Maximum value of T = 88.9 °F
Minimum value of T = 85.9 °F
Step-by-step explanation:
We are given the stated temperature as 87.4 °F
Now, we are told that this stated temperature differs from the actual temperature by no more than 1.5 degrees Fahrenheit.
Thus, if the actual temperature is T, it means that T should either be 1.5 more than 87.4 or 1.5 less than 87.4.
Thus the equation is;
87.4 ± 1.5 = T
So maximum value of T = 87.4 + 1.5 = 88.9 °F
While minimum value of T = 87.4 - 1.5 = 85.9 °F

Andy is buying a car.
He negotiated a 7% decrease on a £6 500 car.
He will pay the full balance in 12 equal monthly payments.
Calculate the amount paid each month.
Answers
Answer:
£503.75
Step-by-step explanation:
Andy is buying a car.
Step 1
We calculate the decrease
He negotiated a 7% decrease on a £6 500 car.
Decrease = 7% × £6500
= $455
Step 2
We calculate the new price of the car.
= Old price - Decrease
= £6500 - £455
= £6045
Step 3
We calculate the amount he pays every month.
We are told that:
He will pay the full balance in 12 equal monthly payments.
Andy's monthly payments =
New price/12 months
= £6045/12
= £503.75
Therefore, the amount he would be paying each new month = £503.75
What is the intrinsic value of the following PUT option? 90 X PUT47.78 52.50 6.44644 1.94 1.88 472 1+2
Answers
The intrinsic value of the PUT option is $0. It means the option has no inherent value based on the given information.
To determine the intrinsic value of a PUT option, we compare the strike price (X) with the current market price (S) of the underlying asset. If the strike price is higher than the market price, the intrinsic value is the difference between the strike price and the market price. However, if the market price is higher than the strike price, the intrinsic value is $0.
In the given information, we have the following data:
- Strike price (X): $90
- Market price (S): $47.78
Since the market price is lower than the strike price (47.78 < 90), the intrinsic value of the PUT option is $0. This means that exercising the option would not result in any profit because it is currently out of the money.

Abby's credit card statement shows a balance of $135.50 at the beginning of the month. During the month she makes purchases of $63.83. Each month a 1.5% interest charge is added to the statement balance. Abby then makes a payment of $50.00. What is her new balance?
Answers
Answer:
$19.64Step-by-step explanation:
Step one:
given data
initial balance= $135.50
1.5% interest charge=0.015 of 135.5= $2.03
purchases= $63.83
payment=$50.00
Step two:
at the beginning of the month, the balance after the %1.5 tax will be
=135.5-2.03=133.47
Also the purchase and the payment amount to 63.83+50=$113.83
the new balance after purchases and payment is
=133.47-113.83
=$19.64

How large should we choose n so that the trapezoid-rule approximation, Tn, to the integral sin r dz is accurate to within 0.00001? (Use the error bound given in Section 5.9 of the course text.)
Answers
The trapezoidal rule is a numerical integration method that uses trapezoids to estimate the area under a curve. The trapezoidal rule can be used for both definite and indefinite integrals. The trapezoidal rule approximation, Tn, to the integral sin r dz is given by:
Tn = (b-a)/2n[f(a) + 2f(a+h) + 2f(a+2h) + ... + 2f(b-h) + f(b)]where h = (b-a)/n. To determine how large n should be so that Tn is accurate to within 0.00001, we can use the error bound given in Section 5.9 of the course text. According to the error bound, the error, E, in the trapezoidal rule approximation is given by:E ≤ ((b-a)³/12n²)max|f''(x)|where f''(x) is the second derivative of f(x). For the integral sin r dz, the second derivative is f''(r) = -sin r. Since the absolute value of sin r is less than or equal to 1, we have:max|f''(r)| = 1.
Substituting this value into the error bound equation gives:E ≤ ((b-a)³/12n²)So we want to choose n so that E ≤ 0.00001. Substituting E and the given values into the inequality gives:((b-a)³/12n²) ≤ 0.00001Simplifying this expression gives:n² ≥ ((b-a)³/(0.00001)(12))n² ≥ (b-a)³/0.00012n ≥ √(b-a)³/0.00012Now we just need to substitute the values of a and b into this expression. Since we don't know the upper limit of integration, we can use the fact that sin r is bounded by -1 and 1 to get an upper bound for the integral.
For example, we could use the interval [0, pi/2], which contains one full period of sin r. Then we have:a = 0b = pi/2Plugging in these values gives:n ≥ √(pi/2)³/0.00012n ≥ 5073.31Since n must be an integer, we round up to the nearest integer to get:n = 5074Therefore, we should choose n to be 5074 so that the trapezoidal rule approximation, Tn, to the integral sin r dz is accurate to within 0.00001.

Find the missing number so that the equation has infinitely many solutions.
4x+15+__x= – 2x+15
Answers
To find the missing number so that the equation has infinitely many solutions in the given expression below;
4x+15+__x= – 2x+15,
We have to solve the given equation in the following manner:
Step 1: Let us begin by simplifying both sides of the equation 4x + 15 + __x = -2x + 15
So, let's add 2x to both sides of the equation.
4x + 15 + __x + 2x = 15
We simplify this to give;
6x + 15 = 15
Step 2: Now, we can solve the equation for x by subtracting 15 from both sides.
6x = 0
x = 0
We can check our solution by substituting the value of x into the equation:
4x + 15 + __x = -2x + 15
Where x = 0.4(0) + 15 + __(0)
= -2(0) + 15__
= 15
Thus, the missing number is 15 as the given equation has infinitely many solutions for the given value of x.

Answers
For the first exam we know that:

\(50\text{ = }\mu_1\text{ - 2.5}\sigma_1\text{ = 75 - 2.5}\cdot10\text{ = 75 - 25}\)For the second exam, we know that:
\(\begin{gathered} \mu_2\text{ = 450} \\ \sigma_2\text{ = 20} \end{gathered}\)To do equivalently, Ayden score must be 2.5 standar deviations away from the mean, so:
\(\text{score}_2\text{ = }\mu_2-2.5\sigma_2\text{ = 450-2.5}\cdot20\text{ = 450-50 = 400}\)Complete the following table by performing the following sequence of operations on the original number:

What is addition property?Regardless of the sequence in which the numbers are added, the total of any two or more numbers is always the same. This characteristic may be expressed in the formula A + B = B + A. For instance, 2 + 4 Equals 4 + 2 = 6. As a result, both sets add up to 6, therefore 2 + 4 = 4 + 2.
We have multiplied both sides of the equation by 5 to move from Step 1 to Step 2:

We have divided both sides of the equation by -3 to go from Step 2 to Step 3:
