The values stored in the list numlist are [0, 2, 4, 6, 8].
The list "numlist" is an array with 10 elements. The values stored in the list depend on the values of "i" as the for loop iterates from 0 to 9.
The "if" statement inside the loop checks if the value of "i" is even using the % operator which returns remainder, and if it is, the value of "i" is stored in the "numlist" at the corresponding index. Therefore, the values stored in the "numlist" would be 0, 2, 4, 6, 8, and the other elements would be left uninitialized.

Jan spends part of her year as a member of a gym. She then finds a better deal at another gym, so she
cancels her membership with the first gym and spends the rest of the year with the second gym. The
membership to the first gym costs $80 per month, while the membership for the second gym costs $45 per

four $12$-sided dice are rolled. what is the probability that the number of dice showing a two digit number is equal to the number of dice showing a one digit number? express your answer as a common fraction. (assume that the numbers on the $12$ sides are the numbers from $1$ to $12$ expressed in decimal.)
27/128 is the probability that the number of dice showing a two-digit number is equal to the number of dice showing a one-digit number.
Probability means Possibility. It states how likely an event is about to happen.
The probability of an event can exist only between 0 and 1 where 0 indicates that the event is not going to happen i.e. Impossibility and 1 indicates that it is going to happen for sure i.e. Certainty.
I'll take a stab at this one. if the number of dice showing a two-digit number = the number of dice showing a one-digit number, then 2 must show a two-digit number and 2 must show a one-digit number
There are 3 two-digit numbers and 9 one-digit numbers on each die
So....the probability is
C(4,2) (3/12)^2 (9/12)^2
C(4,2) (1/4)^2 (3/4)^2
=27/128.

A urvey wa given to people who own a certain type of car. What percent of the people urveyed were completely with the car?
Using the percentage concept, it is found that 60.29% of the people surveyed were completely satisfied with the car.
A percentage is the number of desired outcomes, multiplied by 100%, and divided by the number of total outcomes and also defines a number or ratio that can be expressed as a fraction of 100.
To calculate the percentage, we have to divide the value by the total value and then multiply the resultant by 100.
In this problem, researching the internet, it is found that:
A total of 1260 + 650 + 180 = 2090 people were surveyed.
Of those, 1260 were completely satisfied.
Hence:

Two types of stereos were on sale at a local car stereo dealer.
The J-Series model sold for $II8. The K-Series model sold for $92. During the sale, 32 stereos were sold. The receipts for these stereos totaled $3,230. How many of each type of stereo did the local dealer sell during this sale?
Answer:
11 J- series and 21 K- series
Step-by-step explanation:
create a pair of equations in 2 variables and solve simultaneously.
let x represent J- series and y the K- series , then
x + y = 32 ( subtract x from both sides )
y = 32 - x → (1)
118x + 92y = 3230 → (2)
substitute y = 32 - x into (2)
118x + 92(32 - x) = 3230
118x + 2944 - 92x = 3230
26x + 2944 = 3230 ( subtract 2944 from both sides )
26x = 286 ( divide both sides by 26 )
x = 11
substitute x = 11 into (1)
y = 32 - 11 = 21
11 of J- series and 21 of K- series models were sold

How do you prove a rhombus is not a square?Since a rectangle need not have equal sides, it is not square. Every square is a rectangle and a rhombus. Due to the fact that every square has an equal number of sides, they are all rhombuses. Due of the 90-degree interior angles, all squares are also rectangles.

Dexter thinks of a number, x. He subtracts 4 from his number and multiplies the answer by his original number. His answer is 60 a) Use this information to form a quadratic equation of the form x² + ax + b = 0
Answer:
Let y = x - 4, then xy = 60.
Expanding the product on the right side, we have x(x-4) = 60.
Expanding the left side, we have x² - 4x = 60.
Adding 4x to both sides, we have x² = 60 + 4x.
Re-arranging the equation, we have x² - 4x - 60 = 0.
Thus, the quadratic equation is x² - 4x - 60 = 0.

let be a random variable with pdf where is a constant. find the variance of (write it up to first decimal place).
The variance of the random variable X is 0.
To find the variance of the random variable X, we need to compute its mean (μ) and then calculate the expected value of the squared deviations from the mean.
The variance (σ²) is the average of these squared deviations.
First, let's find the mean (μ):
μ = ∫[x × f(x)]dx
Considering the piecewise function, we can split the integral into two parts:
For -3 < x < 0:
∫[-cx × (-cx)]dx = c² × ∫[x²]dx
= c² × [x³ / 3] between -3 and 0
= c² × (0 - (-3)³ / 3)
= c² × (0 - (-27) / 3)
= c² × (-9)
For 0 ≤ x < 3:
∫[cx × (cx)]dx = c² × ∫[x²]dx
= c² × [x³ / 3] between 0 and 3
= c² × (3³ / 3 - 0)
= c² × (27 / 3)
= c² × 9
Therefore, the mean (μ) is given by:
μ = (-9c² + 9c²) / 6
= 0
Now, let's calculate the expected value of the squared deviations from the mean:
E[(X - μ)²] = ∫[(x - μ)² × f(x)]dx
For -3 < x < 0:
∫[(x - 0)² × (-cx)]dx = c × ∫[x²]dx
= c × [x³ / 3] between -3 and 0
= c × (0 - (-3)³ / 3)
= c × (-27 / 3)
= -9c
For 0 ≤ x < 3:
∫[(x - 0)² × cx]dx = c × ∫[x²]dx
= c × [x³ / 3] between 0 and 3
= c × (3³ / 3 - 0)
= c × (27 / 3)
= 9c
Therefore, the expected value of the squared deviations from the mean is:
E[(X - μ)²] = (-9c + 9c) / 6
= 0
Finally, the variance (σ²) is the average of the squared deviations:
σ² = E[(X - μ)²]
= 0
Hence, the variance of the random variable X is 0.

It is likely that she is on tiptoe, as a pressure of 1,500,000 Pa is a high pressure for a 60 kg person to be applying with just one foot while standing flat on the ground.
How to know if the dancer is tiptoeingThe unit of pressure Pa is equivalent to Newton per square meter
A mass of 60 kg is converted to force by

Pressure = Force / Area
Area = Force / Pressure
Area = 600 N / 1,500,000 Pa
Area = 0.0004 square meter
Area = 4 square centimeter
