Step-by-step explanation:
The average rainfall in December is 4.15 inches. Therefore option C is the answer.
Given that, in Pensacola, Florida, the average rainfall in the month of July is 7.40 inches. By October, the average rainfall decreases by 35%. By December, the average rainfall drops another 0.66 inches.
We need to find the average rainfall, in inches, in December.
What is average rainfall?The term "average annual rainfall" refers to the sum of the yearly precipitation totals for a location during a year as determined by the nearest National Weather Service station over the three decades prior.
In July, rainfall was 7.40 inches. By October, the average rainfall decreases by 35%.
That is, 7.40-35% of 7.40
=7.40-0.35 × 7.40
=7.40-2.59=4.81
By December, the average rainfall drops another 0.66 inches.
That is, 4.81-0.66=4.15
The average rainfall in December is 4.15 inches. Therefore option C is the answer.

Is (1, 7) a solution to this system of inequalities? y < x + 8 y ≤ 6x + 1
Answer:
-8
Step-by-step explanation:
Final answer:
Upon checking both inequalities, the point (1, 7) satisfies y < x + 8 and y ≤ 6x + 1. Thus, (1, 7) is a solution to the system of inequalities.
Explanation:
To determine if the point (1, 7) is a solution to the given system of inequalities, we need to check if the point satisfies both inequalities. The system is:
y < x + 8
y ≤ 6x + 1
For the first inequality:
y < x + 8
7 < 1 + 8
7 < 9 ⇒ True
For the second inequality:
y ≤ 6x + 1
7 ≤ 6(1) + 1
7 ≤ 7 ⇒ True
Since the point (1, 7) satisfies both inequalities, it is indeed a solution to the system.
Solve the inequality: −2x > −6 Question 3 options: x < −3 x > 3 x > −3 x < 3
Answer:
divide both sides of the inequality by -2 and flip the inequality sign the you get (x < 3)
To solve the inequality -2x > -6, divide both sides by -2, remembering to reverse the inequality sign, to obtain x < 3 as the solution.
To solve the inequality -2x > -6, we start by isolating the variable x. To do this, we divide both sides of the inequality by -2. It's important to remember that when we divide or multiply both sides of an inequality by a negative number, we must reverse the direction of the inequality sign. Thus, dividing by -2, the inequality becomes x < 6/2. Simplifying further, we find that x < 3.
Others parts of the referenced information discuss concepts like absolute values, z-scores, and transitivity of numbers but are not directly relevant to solving this inequality.
Hence, the correct answer to the inequality is x < 3.

A candy company is designing the packaging for its new candy bar. the bars will be packed in cartons which are 1 foot long, 1 foot wide, and 1 foot high. how many of these cartons can they pack into the shipping crate which is 5 feet long, 12 feet wide, and 4 feet high?
Answer:
240 cartons
Step-by-step explanation:
First, I need to find the volume of the 2 objects.
If the measurements of the carton is 1 x 1 x 1, ultimately the volume of the carton is 1 cubic foot.
Then, to find the shipping crate volume, multiply 5 x 12 x 4. You will get 240 cubic feet.
Then, we need to find how many cartons can fit in the shipping crate. Divide 240 by 1, and obviously you get 240.
So, 240 cartons can be packed into the shipping crate.

At a carnival, you spin a spinner that has four equal-sized sections, each a different color: green, yellow, red, and blue. If you land on green, you win 2 points. If you land on yellow, red, or blue, you lose 1 point. Write the expected value equation. E (V) = StartFraction 1 Over a EndFraction (2) + StartFraction 1 Over b EndFraction (c) + StartFraction 1 OVer d EndFraction (e) + StartFraction 1 Over f EndFraction (g) a = b = c = d = e = f = g =
Answer:
a = 4
b = 4
c = -1
d = 4
e = -1
f = 4
g = -1
Step-by-step explanation:
To get the expected value equation you have to multiplicate the probability of each outcome by its reward and add them. The probability to get each color is 1/4 because the spinner has four equal-sized sections. If you win money, your reward is positive, but if you lost it, your reward is negative. Then:
expected value equation. E (V) = (1/4)*2 + (1/4)*(-1) + (1/4)*(-1) + (1/4)*(-1) = -0.25
Answer:
A 4
B 4

A plumber charges $130 2 hours of work and $235 for 5 hours of workWhat is the of change in dollars per hour
Final answer:
The plumber charges $35 per hour, calculated by dividing the change in total cost ($105) by the change in hours (3).
Explanation:
To find the rate of change in dollars per hour for the plumber's charges, we need to use the definition of rate of change, which is the change in cost divided by the change in time.
Here are the steps for calculation:
Determine the change in cost: $235 - $130 = $105.Determine the change in time: 5 hours - 2 hours = 3 hours.Calculate the rate of change: $105 ÷ 3 hours = $35 per hour.This means the plumber charges $35 per hour for their service.
Describe the transformation f(x) = √x + 1 − 5 in words. The parent function f(x) = √x has been shifted 1 unit and 5 units.
We conclude that the parent function f(x) = √x has been shifted 1 unit to the left and 5 units downwards.
How was the parent function transformed?
For a function f(x), a vertical translation of N units is written as:
g(x) = f(x) + N
If N is positive, the translation is upwards.If N is negative, the translation is downwards.For a function f(x), a horizontal translation of N units is written as:
g(x) = f(x) + N
If N is positive, the translation is to the left.If N is negative, the translation is to the right.Here we have f(x) = √x, and g(x) = √(x + 1) - 5
Then:
g(x) = f(x + 1) - 5
From this, we conclude that the parent function f(x) = √x has been shifted 1 unit to the left and 5 units downwards.

The sum of a number and 14 is at least 18
The inequality fir the given phrase is x+14≥18, the solution for the obtained inequality is x≥4.
The given phrase is "The sum of a number and 14 is at least 18".
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Let the unknown number be x.
Here, the inequality is x+14≥18
Subtract 14 on both the sides of an inequality, we get
x+14-14≥18-14
x≥4

Final answer:
The sum of a number and 14 is at least 18' can be expressed as the inequality x + 14 >= 18, indicating that the unknown number must be 4 or greater.
Explanation:
The student's question involves setting up an inequality to represent the situation described.
The problem statement, 'The sum of a number and 14 is at least 18,' translates to a mathematical inequality as follows:
Let 'x' represent the unknown number.
The problem states that when you add 14 to this number, the result should be at least 18. Therefore, the inequality would be:
x + 14 >= 18.
To solve this inequality, you would subtract 14 from both sides:
x = 18 - 14
x = 4
This means the unknown number must be 4 or any larger number. In other words, any number greater than or equal to 4, when added to 14, will be at least 18.

Part B: Which one of those two measures of central tendencies should he use for the newspaper and why? Part C: Are there any outliers? Please answer ASAP
Answer:
Part A:
Mean: 129.8
Median: 131.5
Step-by-step explanation:
The mean is the average so we add everything together and then divide it by however many numbers there are. 132 + 141 + 110 + 96 + 154 + 135 + 111 + 139 + 102 + 135 + 133 + 127 + 99 + 124 + 129 + 201 + 131 + 128 + 134 + 135 = 129.8
The median is the number in the middle. That is the number in between the rest from smallest to largest. 96, 99, 102, 110, 111, 124, 127, 128, 129, 131, 132, 133, 134, 135, 135, 135, 139, 141, 154, and 201
The medians are 131 and 132 so we add them together then divide by 2. That gives is 131.5 so that is our answer. I hope this helps and please mark me brainliest!

Answer:
a = -14
Step-by-step explanation:
Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, divide 5 from both sides:
(5(a + 3))/5 = = (-55)/5
a + 3 = -55/5
a + 3 = -11
Next, fully isolate a by subtracting 3 from both sides:
a + 3 (-3) = -11 (-3)
a = -11 - 3
a = -14

The number of mosquitoes in Minneapolis, Minnesota (in millions of mosquitoes) as a function of rainfall (in
centimeters) is modeled by:
m(x) = -(x - 5)2 + 25
How many centimeters of rainfall will produce the maximum number of mosquitoes?
Answer:
5 cm
Step-by-step explanation:
Given the function:
[tex]m(x)=-(x-5)^{2} +25[/tex]
As we know the above function is a quadratic equation (vertical parabola) open downward and the vertex is the maximum number of mosquitoes.
The vertex form of a quadratic function is:
[tex]y=a(x-h)^{2} +k[/tex] where (h,k) is the vertex
Our given function have the vertex form as well, so the
(h,k) = (5,25)
At the height of 5 cm the rainfall will produce the maximum number of mosquitoes
Final answer:
In the function modeling the number of mosquitoes by rainfall, 5 centimeters of rainfall will produce the maximum number of mosquitoes, corresponding to the vertex of the parabola.
Explanation:
To find the number of centimeters of rainfall that will produce the maximum number of mosquitoes in Minneapolis, Minnesota, we look at the vertex of the parabolic function m(x) = -(x - 5)2 + 25. The vertex form of a parabola is given by f(x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. In this equation, h represents the x-value that results in the maximum y-value for the parabola when a is negative, which corresponds to the maximum number of mosquitoes.
In this case, the vertex of the parabola is (5, 25), which tells us that 5 centimeters of rainfall will produce the maximum number, which is 25 million mosquitoes. This value is represented by h in the vertex form of the equation, indicating that the parabola opens downwards (since the coefficient of the (x - h)2 term is negative) and reaches its maximum at x = 5.

Ignoring the "square feet" part, once again, the perimeter is the sum of the lengths of all sides. Since this is a square, all sides have the same length, and there are 4 sides.
perimeter = 4s
perimeter = 4(x + 8) = 4x + 32
