A certain kind of animal weighs about 75 pounds at birth and gains about 2 pounds per day for the first few weeks. Determine those days for which the animal's weight is more than 125 pounds.
The animal's weight is more than 125 pounds when the animal is more than
........... days old.
25
Step-by-step explanation:Let w represent the weight of the animal in pounds, and d the age in days. The problem statement tells us ...
... w = 75 +2d
We want to find d when w > 125.
... 75 +2d > 125 . . . . . substitute the above expression for w
... 2d > 50 . . . . . . . . . subtract 75
... d > 25 . . . . . . . . . . . divide by 2
The animal will weigh more than 125 pounds when it is more than 25 days old.

A bucket contains 3 red balls, 4 yellow balls, and 5 purple balls. one ball is taken from the bucket and is not replaced. another ball is taken from the bucket. what is the probability that the first ball is red and the second ball is purple?
The probabilities are 0.25 and 0.454.
ProbabilityProbability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
Given
A bucket contains 3 red balls, 4 yellow balls, and 5 purple balls.
To findThe probability that the first ball is red and the second ball is purple.
How to find the probability that the first ball is red and the second ball is purple?We know the formula
[tex]\rm Probability = \dfrac{favorable\ events}{total\ events}[/tex]
For the first ball is red, then
Total event = 12
Favorable event = 3
[tex]\rm Probability = \dfrac{favorable\ events}{total\ events}\\\\\rm Probability = \dfrac{3}{12}\\\\\rm Probability = 0.25[/tex]
For the second ball is purple, then
one ball is taken from the bucket and is not replaced
Total event = 11
Favorable event = 5
[tex]\rm Probability = \dfrac{favorable\ events}{total\ events}\\\\\rm Probability = \dfrac{5}{11}\\\\\rm Probability = 0.454[/tex]
Thus the probabilities are 0.25 and 0.454.

The probability that the first ball drawn is red and the second ball drawn is purple, in a situation where the drawn ball is not replaced, is 5/44.
Explanation:In this probability question, we are dealing with a situation where sampling occurs without replacement, meaning, the first ball drawn is not put back into the bucket before the second ball is drawn. This impacts the probability of the outcomes.
There are 3 red balls, 4 yellow balls, and 5 purple balls in the bucket, making a total of 12 balls. The probability of drawing a red ball first is the number of red balls divided by the total number of balls, so P(Red1) = 3/12 = 1/4.
After taking out a red ball, there are now 11 balls left. The probability of drawing a purple ball next is the number of purple balls divided by the new total number of balls. So, P(Purple2 | Red1) = 5/11.
The question asks for the probability that the first ball is red and the second ball is purple. In probability theory, the probability of two independent events happening is computed by multiplying the probability of the first event by the probability of the second event given that the first one has occurred. So, the answer is P(Red1 and Purple2) = P(Red1) * P(Purple2 | Red1) = 1/4 * 5/11 = 5/44.

Find the volume of a square pyramid with a height of 10 m and base edges of 8 m
Final answer:
The volume of a square pyramid with a base edge of 8 m and a height of 10 m is calculated using the formula V = (1/3) x (base area) x (height), which results in a volume of 213.33 cubic meters.
Explanation:
To find the volume of a square pyramid with a base edge of 8 m and a height of 10 m, we can use the formula for the volume of a pyramid, which is V = (1/3) × (base area) × (height). First, we calculate the area of the square base, which is base edge squared, so the base area is 8 m × 8 m = 64 m². Next, we apply the volume formula:
V = (1/3) × (64 m²) × (10 m) = (1/3) × 640 m³ = 213.33 m³
Therefore, the volume of the square pyramid is 213.33 cubic meters.
A ball is thrown into the air with an upward velocity of 32 ft/s. Its height h in feet after t seconds is given by the function h = –16t2 + 32t + 6. a. In how many seconds does the ball reach its maximum height? Round to the nearest hundredth if necessary. b. What is the ball’s maximum height?
a) It will reach the maximum in 1 second;
b) the maximum height is 22 feet.
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
We find the maximum by finding the vertex.
We first find the axis of symmetry, whose equation is,
x = -b/2a
x = -32/2(-16)
x = -32/-32
x = 1
This gives us that it reaches the maximum in 1 second.
And, To find the y-coordinate, the maximum height, we substitute this into the equation:
h(1) = -16(1²)+32(1)+6
h(1) = -16+32+6 = 22
Hence, It reaches a height of 22 feet.

The simple linear regression model is yiequalsbeta0plusbeta1xiplusepsiloni. for what does yi stand? choose the correct answer below.
a. it is the slope of the population regression line.
b. it is the residual of the ith observation in the population.
c. it is the observed value of the response variable for the ith observation in the population.
d. it is the value of the explanatory variable for the ith observation in the population.
e. it is the y-intercept of the population regression line.
In the simple linear regression model, y[tex]_i[/tex] represents the observed value of the response variable for the [tex]i_{th}[/tex] observation. Therefore, the correct answer is option c.
The simple linear regression model is expressed as y[tex]_i[/tex] = β₀ + β₁x[tex]_i[/tex] + ε[tex]_i[/tex]. In this equation, y[tex]_i[/tex] stands for the observed value of the response variable for the i[tex]_{th}[/tex] observation in the population.
The equation y[tex]_i[/tex] = β₀ + β₁x[tex]_i[/tex] + ε[tex]_i[/tex] is used to model the relationship between a single explanatory variable and the response variable.
In this equation, y[tex]_i[/tex] denotes the observed value of the response variable.
The key components include β0 (y-intercept), β1 (slope), xi (explanatory variable), and εi (error term).
So, option c. it is the observed value of the response variable for the i[tex]_{th}[/tex] observation in the population, is the correct answer.

You purchased a share of stock for $30. one year later you received $1.50 as a dividend and sold the share for $32.25. what was your holding-period return?
To calculate the holding-period return, add the dividend, selling price, and initial investment, then divide by the initial investment. In this case, the holding-period return is 12.5%.
Holding-Period Return Calculation:
Initial investment: $30
Dividend received: $1.50
Selling price: $32.25
Holding-Period Return = (Dividends + Selling Price - Initial Investment) / Initial Investment
Substitute the values: ($1.50 + $32.25 - $30) / $30 = $3.75 / $30 = 0.125 or 12.5%
