In a poll, respondents were asked whether they had ever been in a car accident. 215 respondents indicated that they had been in a car accident and 449 respondents said that they had not been in a car accident. If one of these respondents is randomly selected, what is the probability of getting someone who has been in a car accident? Round to the nearest thousandth, if necessary
Answers
The probability of getting someone who has been in a car accident will be 0.3238
Number of people that indicated that they had been in a car accident = 215 respondents
Number of people that said that they had not been in a car accident = 449
The probability of getting someone who has been in a car accident will then be calculated as:
= 215/664
= 0.3238
Therefore, the probability of getting someone who has been in a car accident will be 0.3238

Bill Payne visits his local bank to see how long it will take for $1,000 to amount to $1,900 at a simple interest rate of 12 ½%. Provide Bill with the solution to his problem in years
Answers
It will take approximately 0.72 years for $1,000 to accumulate to $1,900 at a simple interest rate of 12 ½%.
Explanation:To find out how long it will take for $1,000 to amount to $1,900 at a simple interest rate of 12 ½%, we can use the simple interest formula:
Interest = Principal × Rate × Time
Where:
Substituting the values into the formula:
Interest = $1,900 - $1,000
$1,900 - $1,000 = $900
$900 = $1,000 × 0.125 × Time
To find Time, we can rearrange the formula:
Time = $900 / ($1,000 × 0.125)
Time = 0.72 years
Therefore, it will take approximately 0.72 years for $1,000 to accumulate to $1,900 at a simple interest rate of 12 ½%.

The equation of parabola is y = ( x - 2 )² + 3
What is a Parabola?
A Parabola, open curve, a conic section produced by the intersection of a right circular cone and a plane parallel to an element of the cone. A parabola is a plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line
The equation of the parabola is given by
( x - h )² = 4p ( y - k )
where ( h , k ) is the vertex and ( h , k + p ) is the focus
y is the directrix and y = k - p
The equation of the parabola is also given by the equation
y = ax² + bx + c
where a , b , and c are the three coefficients and the parabola is uniquely identified
Given data ,
The vertex of the parabola is given as A ( 2 , 3 )
Now ,
The equation of parabola is given by
y = a ( x - h )² + k
where the vertex of the parabola is A ( h , k )
a = 1
So , substituting the values of vertex in the equation of parabola , we get
y = ( x - 2 )² + 3
Hence , the equation of parabola is y = ( x - 2 )² + 3

A survey asks 1200 workers, "has the economy forced you to reduce the amount of vacation you plan to take this year?" Thirty-five percent of those survey selected. The random variable represents the number of workers who are reducing the amount of vacation. Find the mean, variance and standard deviation of the binomial deviation of the binomial distribution.
Answers
In this case, n = 1200, p = 0.35. So, mean = (1200)(0.35) = 420,
variance = (1200)(0.35)(1–0.35) = 273,
standard deviation = square root of variance = √273 = 16.52.
The probability of an event is defined as the possibility of an event occurring against sample space.
Let us tackle the problem.
A survey asks 1200 workers → n = 1200
Thirty-five percent of those survey selected → p = 35% = 0.35
To find the mean of a binomial distribution, we can use the following formula:
[tex]Mean = n \times p[/tex]
[tex]Mean = 1200 \times 0.35[/tex]
[tex]\boxed {Mean = 420}[/tex]
To find the variance of a binomial distribution, we can use the following formula:
[tex]Variance = n \times p \times (1 - p)[/tex]
[tex]Variance = 1200 \times 0.35 \times (1 - 0.35)[/tex]
[tex]Variance = 1200 \times 0.35 \times 0.65[/tex]
[tex]\boxed {Variance = 273}[/tex]
To find the standard deviation of a binomial distribution, we can use the following formula:
[tex]Standard ~ Deviation = \sqrt{Variance}[/tex]
[tex]Standard ~ Deviation = \sqrt{273}[/tex]
[tex]\boxed {Standard ~ Deviation \approx 17}[/tex]

The Junior Soccer League takes 12-person vans to the tournament. The league has 146 players and 14 coaches. How many vans are needed and how many people are left over?
Answers
Final answer:
The Junior Soccer League will need a total of 14 vans to transport 160 people, with 4 people left over after filling the 13th van.
Explanation:
To calculate the number of 12-person vans needed for the Junior Soccer League event, we first need to determine the total number of people that require transportation. This includes both players and coaches.
We have 146 players and 14 coaches, giving us a total of 160 people. If each van holds 12 people, the next step is to divide the total number of people by the capacity of the van.
Divide the total number of people by the capacity of the van (12).Calculate the number of full vans required.Determine if there are any people left over.160 ÷ 12 = 13 vans with 4 people left over because 12 vans can only carry 144 people (12 × 12), and 16 people are remaining, which requires another van to accommodate them.
So, the league will need a total of 14 vans for transportation, and there will be 4 people left over after filling the 13th van.

Use the distributive property to write the products as sums:7(4n-5m-2)
Answers
The distributive property is used to multiply 7 by each term inside the parentheses (4n, -5m, -2) resulting in the expression 28n - 35m - 14.
Explanation:To apply the distributive property to the expression 7(4n-5m-2), you multiply each term inside the parentheses by 7. The distributive property allows us to multiply a single term outside a parenthesis with each term inside the parenthesis, effectively distributing the multiplication.
First term: 7 × 4n = 28nSecond term: 7 × -5m = -35mThird term: 7 × -2 = -14Therefore, the product written as a sum, using the distributive property, is 28n - 35m - 14.

Take the limit as x approaches 8 to get the answer of 9.
Explanation:To find the limit of (x² - 64) / (x² - 8x) as x approaches 8, we can simplify the expression by factoring and cancelling common factors.
First, we factor in the numerator and denominator:
x² - 64 = (x + 8)(x - 8) and x² - 8x = x(x - 8).
Now we can cancel the common factor of x - 8 to simplify the expression: (x + 8)/(x).
Now, we can take the limit as x approaches 8:
Lim(x→8) (x + 8)/(x) = 8 + 8/8
= 9.
So the limit of the given expression as x approaches 8 is 9.

Expressions equivalent to 'log 2 - log 6' are based on the property of logarithms that states 'log a - log b' is equivalent to 'log (a/b)'. Thus, the equivalent expression is 'log (1/3)'.
The expressions equivalent to log 2 - log 6 can be found using the property of logarithms that deals with the difference of logarithms. According to this property, log a - log b is equivalent to log (a/b). Therefore, one equivalent expression for log 2 - log 6 would be log (2/6), which can be simplified to log (1/3).

The first truck in a convoy will carry 12 tons of dirt while each additional truck will carry 8 tons of dirt. Write a rule to model th situation. Then use the rule to find how many tons of dirt can be carried by 7 trucks. Let n represent the number of trucks and t represent the tons of dirt.
Answers
68 tons of dirt will be hauled
Final answer:
To model the situation, use the rule t = 12 + 8(n - 1), where n is the number of trucks. Applying this rule, 7 trucks can carry a total of 60 tons of dirt.
Explanation:
The student should write a rule to model the situation where the first truck carries 12 tons of dirt and each subsequent truck carries 8 tons. The rule can be defined as t = 12 + 8(n - 1), where n represents the number of trucks and t represents the total tons of dirt carried. For 7 trucks, we can plug in the value of n into the equation:
t = 12 + 8(7 - 1)
t = 12 + 8(6)
t = 12 + 48
t = 60 tons
Therefore, 7 trucks can carry a total of 60 tons of dirt.

Saylor Henshaw earned $120 in simple interest in 9 months at an annual interest rate of 5%. How much money did he invest?
Answers
Saylor Henshaw invested $1600.
Explanation:To find out how much money Saylor Henshaw invested, we can use the formula for simple interest:
Interest = Principal × Rate × Time
In this case, Saylor earned $120 in 9 months at an annual interest rate of 5%.

Ex.
1H 2H 3H 4H 5H 6H
1T 2T 3T 4T 5T 6T
Answer:
12 ways
Step-by-step explanation:
We know that,
When the cube is rolled,
Possible ways = 6 ( i.e. 1, 2, 3, 4, 5 or 6 ),
While, when a penny is flipped,
Possible ways = 2 ( i.e. head or tail ),
Thus, when the cube and penny flipped one time,
Total possible ways = 6 × 2 = 12
( i.e, 1H, 2H, 3H, 4H, 5H, 6H, 1T, 2T, 3T, 4T, 5T or 6T )
