The approximate elevation change per minute for the submarine is -109.5 feet.
Explanation:To find the approximate elevation change per minute, we need to divide the total elevation change by the total time taken. The submarine's elevation changes by -657 feet over a period of 6 minutes. So, we divide -657 by 6 to get the approximate elevation change per minute.
-657 / 6 = -109.5 feet
Therefore, the approximate elevation change per minute is approximately -109.5 feet.

Sam decides to build a square garden. If the area of the garden is 9x2 − 24x + 16 square feet, what is the length of one side of the garden?
(3x + 4) feet
(3x − 4) feet
(4x − 3) feet
(4x + 3) feet ...?
Answer: The correct option is (B) [tex](3x-4).[/tex]
Step-by-step explanation: Given that Sam decides to build a square garden whose area is as follows:
[tex]A=9x^2-24x+16~\textup{square feet}.[/tex]
We are to find the length of one side of the garden.
Since the given garden is of a square shape, so the length of each side is same.
That is, the area of the garden must be a perfect square trinomial.
We have
[tex]A\\\\=9x^2-24x+16\\\\=(3x)^2-2\times 3x\times 4+4^2\\\\=(3x-4)^2.[/tex]
Since the area of a square is (length)², so the length of one side of the garden is [tex](3x-4)~\textup{feet}.[/tex]
Thus, (B) is the correct option.
A box contains four 40-W bulbs, five 60-W
bulbs, and six 75-W bulbs. If bulbs are se-
lected one by one in random order, what is
the probability that at least two bulbs must be
selected to obtain one that is rated 75W?
Answer: 0.99483
Step-by-step explanation:
Given : A box contains four 40-W bulbs, five 60-W bulbs, and six 75-W bulbs.
Total bulbs : 4+5+6=15
The probability of selecting a 75-W bulb :[tex]p=\dfrac{6}{15}=0.4[/tex]
Using the binomial probability :-
[tex]P(X)= ^nC_xp^x(1-p)^{n-x}[/tex], where P(x) is the probability of getting success in x trials , p is the probability of getting success in each trial and n is the total number of trials.
We have,
The probability that at least two bulbs must be selected to obtain one that is rated 75W :-
[tex]P(x\geq2)=1-(P(x<2))\\\\=1-(P(x=0)+P(x=1))\\\\=1-(^{15}C_0(0.4)^0(0.6)^{15}+^{15}C_{1}(0.4)^1(0.6)^{14})\\\\=1-((1)(0.6)^{15}+(15)(0.4)(0.6)^{14})\ \ [\because\ ^nC_0=1\ \&\ ^nC_1=n]\\\\\approx1-(0.00047+0.00470)\\\\=1-0.00517=0.99483[/tex]
Hence, the required probability = 0.99483

"Which of the following are remote interior angles of 5? Check all that apply.
A.1
B.2
C.3
D.4
E.5
F. 6"
Answer:
A. 1
B. 2
Step-by-step explanation:
We have been given an image of a triangle. We are asked to find remote interior angles of angle 5 for our given triangle.
We can see that angle 5 is an exterior angle. We know that remote interior angles are those, which are inside the triangle and opposite to exterior angle.
We can see that angle 2 and angle 1 are are opposite angles of angle 5 and they are inside our given triangle.
Therefore, option A and B are correct choices.
Final answer:
Remote interior angles are non-adjacent angles within the same triangle. Relative to angle 5, angle 1 and angle 2 are remote interior angles because they are inside the triangle and do not share a vertex with angle 5.
Explanation:
In this mathematics problem, we are asked to find the remote interior angles of a given angle, which are angles that are inside the triangle and non-adjacent to the exterior angle being considered. For example, if we have a triangle with angles labeled 1, 2, 3, 4, 5, and 6, and we want to find the remote interior angles relative to angle 5, we would look for the angles inside the triangle that do not share a vertex with angle 5.
From the available options:
Angle 1 and angle 2 qualify as remote interior angles relative to angle 5 because they are non-adjacent to angle 5 and are within the same triangle.Angle 3 is adjacent to angle 5, so it is not a remote interior angle.Angles 4, 5, and 6 are not pertinent in this case because the question is specifically about the remote interior angles of angle 5, making angles 4 and 6 external to the triangle, whereas angle 5 is the angle in question itself.Therefore, options A (1) and B (2) are the correct answers to this problem.

For the demand equation, express the total revenue R as a function of the price p per item.
q = −5p + 500
R(p) = ?
The total revenue (R) can be expressed as a function of the price (p) per item by multiplying the price by the quantity demanded (q). Given the demand equation q = -5p + 500, the total revenue equation is R(p) = -5p^2 + 500p.
Explanation:The total revenue (R) can be expressed as a function of the price (p) per item by multiplying the price by the quantity demanded (q).
Given the demand equation q = -5p + 500, we can substitute q in the total revenue equation with -5p + 500:
R(p) = p * (-5p + 500)
Simplifying, we distribute p to both terms inside the parenthesis:
R(p) = -5p^2 + 500p
So, the total revenue (R) as a function of price (p) is R(p) = -5p^2 + 500p.

Determine the value c so that each of the following
functions can serve as a probability distribution of
the discrete random variable
X:(a)
f(x) =c(x2+ 4), for x= 0,1,2,3;
(b)f(x) =c(choose x from2)(choose 3 from 3-x) for x= 0,1,2.
The value of c, which must be determined for a discrete random variable to serve as a probability distribution, should be 1/30 for the function f(x) = c(x^2 + 4) and 1/3 for the function f(x) = c(choose 2 from x)*(choose 3 from 3-x).
Explanation:The value of c for a probability distribution needs to be determined such that the total sum of the probabilities is equal to 1. For this, we need to calculate the sum of all possible outcomes and then normalize it to 1.
For the function f(x) = c(x2 + 4), where x = 0, 1, 2, 3, the total sum of the outcomes without the multiplying factor, c, is (02+4) + (12+4) + (22+4) + (32+4) = 4 + 5 + 8 + 13 = 30. The factor c then must be 1/30 for the probabilities to sum up to 1.For the function f(x) = c(choose 2 from x)*(choose 3 from 3-x), where x = 0, 1, 2, the total sum of outcomes without c is (choose 2 from 0)*(choose 3 from 3) + (choose 2 from 1)*(choose 3 from 2) + (choose 2 from 2)*(choose 3 from 1) = 0 + 0 + 3 = 3. Therefore, the factor c for this function must be 1/3.Learn more about Probability Distribution here:https://brainly.com/question/14210034

0.12
0.40
0.20

The probability that Pam will not purchase either car A or car B is 0.20.
What is probability?Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,

Probability that she will purchase car B = 0.34
The probability that she will purchase either car A or car B is
⇒ [tex]0.46+0.34[/tex]
⇒ [tex]0.80[/tex]
Thus the probability that she will not purchase either car A or car B is
⇒ [tex]P(A)=1-0.80[/tex]

At a farmer’s market, a basket of strawberries costs $20 and a basket of peaches costs $18. On Saturday, $430 worth of strawberries and peaches were sold, and a total of 23 baskets were sold. If x represents baskets of strawberries and y represents baskets of peaches, how many baskets of peaches were sold on Saturday?
20x+18y=430
x+y=23
8 baskets
11 baskets
12 baskets
15 baskets
Final answer:
To find the number of baskets of peaches sold on Saturday, we can set up a system of equations and solve it using elimination or substitution. The answer is 15 baskets Option Dof peaches.
Explanation:
To solve this problem, we need to use a system of equations. Let's call the number of baskets of strawberries x and the number of baskets of peaches y. We can set up the following equations:
20x + 18y = 430 (equation 1)
x + y = 23 (equation 2)
We can solve this system of equations using substitution or elimination. Let's use elimination:
Multiply equation 2 by 18 to make the coefficients of y in both equations cancel:
18x + 18y = 414 (equation 3)
Subtract equation 3 from equation 1 to eliminate y:
(20x + 18y) - (18x + 18y) = 430 - 414
2x = 16
Divide both sides of the equation by 2:
x = 8
Substitute x = 8 into equation 2 to find y:
8 + y = 23
y = 23 - 8
y = 15
Therefore, 15 baskets of peaches were sold on Saturday.
