determine if the numerical value describes a population parameter or a sample statistic. the average price of a house in the new subdivision is $257,000.
The numerical value in this sentence, "the average price of a house in the new subdivision is $257,000" describes a Population Parameter.
What is a Population Parameter?A population parameter is a figure that describes a fact about a whole population. In this sentence, we can see that the figure quoted is representative of an entire population. A sample statistic, on the other hand, describes something about a part of a population.
So, for the statement above, we can see that the average price is representative of all the houses in the new subdivision. Thus, the figure is a population parameter.

The digit 8 in Carla’s number represents 10 times of what the digit 8 represents in Travis’ number.
The number written by Carla = 814,247
The number written by Travis = 683,571
The place value of digits starting from left is ones, ten's, hundreds, thousands, ten thousand, hundred thousand and so on.
As per this sequence of values, we can see that digit 8 in Carla's number is at hundred thousand place value. Also, digit 8 in Travis' number is at ten thousand place value. So, representing these place value in numeral form and finding the number of times one is greater than other.
Digit 8 in Carla's number: 100,000
Digit 8 in Travis' number: 10,000
Finding the answer -
Value = 100,000 ÷ 10,000
Cancelling common zeroes from numerator and denominator
Value = 10

For a real number a, a + 0 = a is that true?
For a real number a, a + 0 = a: TRUE
What are real numbers?In mathematics, a real number is a quantity that can be expressed as an infinite decimal expansion. In contrast to the natural numbers 1, 2, 3,..., which are derived from counting, real numbers are used in measurements of continuously varying quantities such as size and time.For a real number a, a + 0 = a:
This is due to the identity property for addition, which states that zero added to any number equals the number itself. So, in this case, the number is, and it is true that: a + 0 = aTherefore, the statement "for a real number a, a + 0 = a" is TRUE.

f(x) = 3x²-x+ 5, 2f(-3) - f(4) =
Answer:
21
Step-by-step explanation:
You want the value of the expression 2f(-3)-f(4), given that f(x) = 3x²-x+ 5.
Function evaluationA function is evaluated by putting the argument where the variable is, and simplifying the result. Polynomials are often easier to evaluate if they are written in Horner form.
f(x) = 3x² -x +5
f(x) = (3x -1)x +5
The values we need are ...
f(-3) = (3(-3) -1)(-3) +5 = (-10)(-3) +5 = 35
f(4) = (3(4) -1)(4) +5 = (11)(4) +5 = 49
Then the expression of interest has the value ...
2f(-3) -f(4) = 2(35) -49 = 70 -49
2f(-3) -f(4) = 21

Let us suppose Christmas lights have a total of 120 bulbs in a set, each with a 99.9% reliability rating. What is the probability that a set all works?
The probability that a set of all bulbs work is 0.88.
What is called as the total probability?The total probability rule (also known as the Law of Total Probability) divides probability calculations into discrete steps.
It's used to calculate the probability of an event, A, once you don't know enough about A's probabilities to do so directly. Instead, you use a related event, B, to calculate the probability of A.Two events are considered independent if a occurrence of one does not affect the likelihood of occurrence of the other.Now, as per the question;
The total number of bulbs be 120 and each bulb is working as independent event.
The reliability of each bulb is 99.9% = 0.999
Let 'p' the probability the bulb will work.
The probability that all will work = p¹²⁰
The probability that all will work = (0.999)¹²⁰ = 0.886
Thus, the probability that all bulb will work is 88.6%.

Answer:
No solution
Step-by-step explanation:
You can solve this in a few ways. One way is to graph the equation, and the solution is the x-value of the point of intersection. Another way would be to factor, which is more difficult to complete with a square bigger than 2.
By graphing, you can see a parabola that never touches that x-axis, which means no solution.

If participant A's batting common is .312 and he had 596 at-bats , what number of hits did he get?
The number of hits A got is 186 hits.
A player's batting average is calculated by dividing the number of hits by the number of at-bats.
Player A batting average = 0.312
Number of at-bats A did = 596
We have to find the number of hits A got.
0.312 = Number of hits / 596
Number of hits = 0.312 x 596

Katy invests a total of $10,500 in two accounts paying 11% and 5% simple interest, respectively. How much was invested in each account if, after one year, the total interest was $945.00.
A) Enter an equation that uses the information as it is given that can be used to solve this problem. Use x as your variable to represent the amount of money invested in the account paying 11% simple interest.
Equation:___________
B) The answers are:
$____ was invested at 11% and
$____was invested at 5%
Answer:
Equation: 0.11x + 0.05(10500 - x) = 945
$7000 was invested at 11% and
$3,500 was invested at 5%
Step-by-step explanation:
There are two equations needed
Let x = amount of money invested at 11%
11% = 11/100 = 0.11 in decimal
Interest at 11% for 1 year = 0.11x
Amount of money invested at 5% interest. 5% = 0.05
= 10500 - amount invested at 11%= 10500 - x
Interest from this amount after 1 year = 0.05(10500 - x)
Total of these two = 945
So 0.11x + 0.05(10500 - x) = 945
The equation based on the information as it is given:
0.11x + 0.05(10500 - x) = 945
We know the total interest obtained was $945 so we have the equation
0.11x + 0.05(10500- 5x) = 945
Simplify
0.11x + (525 - 0.05x) = 945
==>0.11x + 525 - 0.05x = 945
==> 0.06x = 945 - 525
==> 0.06x = 420
==> x = 420/0/06 = $7000
Amount invested at 11% interest is $7,000
Amount invested at 5% interest = 10,500 - 7,000 = $3,500

Mother spent (4r - 8) dollars more on cherries than did the father.
An expression using numbers and related operations is called a numerical expression.
According to the question, a pound of cherries costs $4.
Mom purchased r pounds.
The price of the cherry is calculated as follows: 4r = weight x $/lb.
Father purchased 2 pounds, thus the price of the cherries is 4 (2), or $8.
We remove the smaller value from the higher value, which is 4r - 8, where r must be more than two. Given that the mother spent more money on cherries than the father, the mother's cost of cherries is a greater value.
