∙Let random variable XX represent the number of accidents due to speed violation among 8 automobile accidents.
Lets consider it success if an accident is due to speed violation.
-Probability of a success in each trial is p = 6/10 = 0.6
-Because the trials are independent, XX has a binomial distribution with parameters n = 8n=8 and p = 0.60p=0.60
The probability that among 8 automobile accidents, 6 will be due mainly to a speed violation will be 0.75.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
It is given that, the probability that among 8 automobile accidents, 6 will be due mainly to a speed violation.
In everyday life, risk modeling and assessment involve the use of probability theory. Actuarial science is used by the insurance sector and markets to set pricing and decide which securities to trade. Environmental regulation, entitlement analysis, and financial regulation are all areas where governments use probabilistic methods.
Probability =favorable outcome/ total outcome
Probability = 6/8
Probability =0.75
Thus, the probability that among 8 automobile accidents, 6 will be due mainly to a speed violation will be 0.75.

Mrs. Williams is deciding between two field trips for her class. The Science Center
charges $114 plus $3 per student. The Dino Discovery Museum simply charges $6
per student. For how many students will the Science Center charge less than the
Dino Discovery Museum?
For more than
students.
HELP!!!!
Science Center: 114 + (3 * x)
Dino Museum: 6 * x
114+(3*x) = 6*x
114+(3*39) = 6*39
114+117 = 234

I’m stuck on a math problem. It’s asking..
You plan to purchase a house for $425,000 and you will make a 30% down payment. You are evaluating two mortgages a 30-year fixed mortgage at 2.77% and a 15 year fixed mortgage at 2.15%. Your goal is to have a monthly payment that fits within your budget.
A. Which mortgage will give you the lowest monthly payment . What will that payment be. How much less will this be than the other monthly mortgage payment.
B. Assuming you take the full term of the mortgage, which mortgage will result in you paying the most interest. What will that interest be? How much less will this be than the interest on on the other mortgage?
Answer:
A. 30 years at 2.77%; $1217.67; $717.38 lower
B. 30 years at 2.77%; $140861.72; $90,051.68 difference
Step-by-step explanation:
A suitable spreadsheet, calculator, or financial app can help you answer these questions. In the attachments, we show the result of using a TI-84 work-alike calculator's financial app.d
A.The lowest monthly payment generally results from the longest-term mortgage, even when the interest rate is slightly higher. Here, the lowest payment is $1217.67 on the 30-year loan. It is $717.38 lower than the payment on the 15-year loan.
__
B.The longer-term loan will generally require payment of more interest. Here, that is made worse by the higher rate on the longer loan. The interest is the sum of payments less the initial principal. The highest amount of interest is $140,861.72 on the 30-year loan. That is $90,051.68 more than for the 15-year loan. (The wording of the question seems to be confused.) The least interest amount is $50,810.04 on the 15-year loan.
Adding and subtracting fractions with different denominators D:
Answer:
(I only did question 11 because the rest is just repetition)
Step-by-step explanation:
make the denominators the same by finding the LCM (lowest common multiple)
(I apologise if I do this incorrectly, the image is very blurry)
So what I did was make the denominator a number that both 2 and 3 can multiply to. (2x3=6 and 3x2=6)
Then whatever you do to the bottom you always do to the top.
- to go from 2 to 6, multiply by 3
- do that to the numerator
- to get from 3 to 6, multiply by 2
- do that to the numerator
= 17/6

Answer:
Step-by-step explanation:
1) Find the minimum and maximum values for the function with the given domain interval. Round your answers to the nearest thousandth. m(x) = ln x, given 1/10 ≤ x ≤ 1/5
The function m(x) = ln x is a natural logarithm function
The minimum value is -2.30 and the maximum value is - 1.61
How to determine the minimum and maximum values?The function is given as:
m(x) = ln x
The domain is given as:
1/10 ≤ x ≤ 1/5
At x = 1/10, we have:
m(1/10) = ln (1/10)
m(1/10) = -2.30
At x = 1/5, we have:
m(1/5) = ln (1/5)
m(1/5) = -1.61
So, we have: -2.30 ≤ m(x) ≤ -1.61
Hence, the minimum value is -2.30 and the maximum value is - 1.61

Your distance from lightning varies directly with the time it takes you to
hear thunder. If you hear thunder 10 seconds after you see the lightning,
you are about 2 miles from the lightning. Estimate how many seconds it
would take for the thunder to travel a distance of 4 miles? *
Answer:
d = 1/5t
Step-by-step explanation:
Since it is a direct variation , Let d represent the distance and t represent the time ,then
d ∝ t
introducing the proportionality constant, we have
d = kt
Substituting t = 10 and d = 2 , we have
2 = 10k
k = 1/5
substitute k = 1/5 into the original equation , we have
d = 1/5t

What is sine of an angle?The sine of an angle is the ratio of perpendicular to its hypotenuse.
Mathematically,
Sine of an angle = Perpendicluar/Hypotenuse
Now, it is given that a △JKL.
To find sine K we need to find the hypotenuse and Perpendicular of the triangle.
Since, Sine of an angle = Perpendicluar/Hypotenuse
So, sin K = Perpendicluar/Hypotenuse
Since K is the angle given so opposite of the angle K must be the perpendicular.
So, Perpendicular of the △JKL = JL
So, Hypotenuse of △JKL = JK or KL.
Since from the given option, it can be concluded that JK is the hypotenuse of △JKL.
Therefore, sin K = JL/JK
Thus, the ratio to be used to find sink is A. JL : JK

The value of a collectible coin can be represented by the equation y = 2 x + 9.74, where x represents the number of years that Consuello has owned the coin and y represents the total value, in dollars, of the coin. What was the value of the coin when Consuello originally purchased it?
$4.87
$7.74
$9.74
$19.48
Answer:
The value of the coin when Consuelo originally purchased it is $9.74 ⇒ C
Step-by-step explanation:
The form of the linear equation is;
y = m x + b, where
m is the slope of the line (The rate)b is the y-intercept (initial amount, value y at x = 0)∵ The value of a collectible coin can be represented by the equation
y = 2 x + 9.74
→ Compare it with the form of the linear equation above
∴ m = 2
∴ b = 9.74
∵ x represents the number of years that Consuelo has owned the coin
∵ y represents the total value, in dollars, of the coin
→ That means the value of y at x = 0 is the value of the coin when
Consuelo originally purchased it
∵ b represents the value of y at x = 0
∵ b = 9.74
∴ The value of the coin when Consuelo originally purchased it is $9.74

Step-by-step explanation:
I don't see answer options, but I can very well guess what went wrong :
he used the area formula to calculate the perimeter.
the area would be length × width, in our case
6 × 5 = 30 units²
but the perimeter is 2×length + 2×width, in our case
2×6 + 2×5 = 12 + 10 = 22 units

Hope this helps!If it does, give thanks!A rectangle has an area of 24x + 6. What are all the possible side lengths of the rectangle.
The required possible side lengths of the rectangle are B. 2 and 12x+3 and C. 3 and 8x + 2.
What is a rectangle?The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.
Here,
The area of a rectangle is given by the formula A = l x w, where l is the length and w is the width of the rectangle.
We know that the area of the rectangle is 24x + 6, so we can set up the equation:
24x + 6 = l x w
We want to find all possible combinations of length and width that satisfy this equation.
One way to approach this is to factor the expression 24x + 6 and look for pairs of factors that multiply to give the same product.
24x + 6 = 6(4x + 1)
Now we can see that one possible set of dimensions is:
l = 6(4x + 1)
w = 1
This gives us an area of:
A = l x w = 6(4x + 1) x 1 = 24x + 6
Another possible set of dimensions is:
l = 2(12x + 3)
w = 3
This gives us an area of:
A = l x w = 2(12x + 3) x 3 = 24x + 6
So the possible side lengths of the rectangle are:
l = 6(4x + 1), w = 1
l = 2(12x + 3), w = 3
