The linear equation that represents the plant height is the one in the first option:
y = 14 + (3/2)x
Which linear equation represents the height?We know that the initial height of the plant (this will be the y-intercept of the line) is 14cm, and we also know that the plant grows at a rate of 3/2 cm each day.
So, after x days, the plant is x times 3/2cm plus 14 cm of height, so the linear equation is:
y = 14 + (3/2)x
So the correct option is the first one.

Find the measures of two complementary angles if the measure of the larger angle is 2 less than 3 times the measure of the smaller angle.
Answer:
Let x be the larger angle and y be the smaller angle
Larger angle is 2 less than 3 times the smaller angle that is x = 3y - 2
As the angles are complementary, their sum equals 90°
or, x + y = 90°
or, 3y - 2 + y = 90°
or, 4y = 92°
or, y = 23°
So, x = 3 * 23 - 2 = 67°
Larger angle = x = 67°
Smaller angle = y = 23°

Based on the values you've listed, it appears that the expression P(7, 5) represents a combination calculation. In combinatorics, the notation P(n, k) represents the number of ways to choose a subset of k items from a set of n items, without regard to the order in which the items are chosen. This is also known as the number of k-permutations of n items.
In this case, the expression P(7, 5) would represent the number of ways to choose a subset of 5 items from a set of 7 items. Using the formula for combinations, this would be calculated as follows:
P(7, 5) = 7! / (5! * (7 - 5)!)
= 7! / (5! * 2!)
= 7 * 6 * 5 * 4 * 3 / (5 * 4 * 3 * 2 * 1 * 2 * 1)
= 7 * 6 / 2
= 21
Therefore, the correct answer for the expression P(7, 5) is 21.

Is this a reasonable estimate?
The estimate made by Warner is 95% reasonable.
What is inequality? What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that Warner received 7 letters and each letter weighed between 3.92 ounces and 4.1 ounces.
If the we take the maximum possible weight of each letter, which is 4 ounces, then the total weight of 7 letters will be equal to (4 x 7) = 28. But since the weights are weighted between 3.92 ounces and 4.1 ounces, let us assume that the weight of each letter is equivalent to -
w(a) = (3.92 + 4.10)/2 = 8.02/2 = 4.01
So, the weight of 7 letters would be -
W{7} = w(a) x 7 = 7 x 4.01 = 28.7
28.7 = 29 (round off) ≈ 30
So, yes the estimate of the Warner is reasonable.
Therefore, the estimate made by Warner is 95% reasonable.

unpaid lunch. If Marvin earns $14.75 per hour, answer the following.
How many hours and minutes does Marvin work for the week?
What is Marvins gross pay?
Answer:
The answer is $492.88. This is Marvin's gross pay for the week, calculated by multiplying his hourly wage of $14.75 by the number of hours he worked, which is 33.5 hours.
Step-by-step explanation:
Marvin works 6 hours a day on Monday through Thursday, for a total of 6 * 4 = <<64=24>>24 hours.
On Saturday he works 8.5 hours, for a total of 24 + 8.5 = <<24+8.5=32.5>>32.5 hours.
Marvin works for 30 minutes unpaid during the week, and 30 minutes unpaid on Saturday for a total of 30 * 2 = <<302=60>>60 minutes.
In hours, 60 minutes is 60 / 60 = <<60/60=1>>1 hour.
Therefore, Marvin works for a total of 32.5 + 1 = <<32.5+1=33.5>>33.5 hours in a week.
Marvin earns $14.75 per hour, so his gross pay is 14.75 * 33.5 = $<<14.75*33.5=492.88>>492.88

a coin is tossed and a die is rolled. find the probability of getting a head and a number greater than 5
The probability of getting a head and a number greater than 5 i.e, independent events is 0.0833.
A coin is tossed and a die is rolled. These are two independent events. Two events are defined as independent if the outcome of one event has no effect on the outcome of another event. The probability is calculated by multiplying two independent probabilities together, i.e, P(A and B) = P(A) x P(B)
We have, Let us assume two independent events be ,
A : A coin is tossed and the head is thrown.
B : A die is rolled, and a number greater than 5 occurs.
Total possible outcomes when a coin tossed = 2 ={ H ,T }
Total possible outcomes when a die rolled = 6 = { 1,2,3,4,5,6} .
We have to determine probability of getting a head and a number greater
than 5.
Probability of getting the head on toss a coin, P(A) = 1/2
Probability of occuring a number greater than 5 on rolling a die = P(B) = 1/6
So, the probability of getting a head on coin and a number greater than 5 on die =P(A)×P(B)
