Assume that 600 births are randomly selected and 26 of the births are girls. Use subjective judgment to describe the
number of girls as significantly high, significantly low, or neither significantly low nor significantly high.
Choose the correct answer below.
A. The number of girls is significantly low.
B. The number of girls is neither significantly low nor significantly high.
C. The number of girls is significantly high.
D. It is impossible to make a judgment with the given information.
With the aid of subjective judgment, we can describe the number of girls as; A. The number of girls is significantly low.
How to interpret subjective judgement?Subjective judgement is simply defined as something that is subjective is based on personal opinions and feelings rather than on facts.
Now, we are told to assume that 600 births are randomly selected and 26 of the births are girls.
Now, we see that the total number of births are assumed as 600.
Now, since only 26 of that size are seen to be girls, then it means that;
Percentage that are girls = (26/600) * 100 = 4.33%
Thus, using subjective judgement we see that the percentage that are girls is so low that it is even lower than 5%. Thus, we can say that The number of girls is significantly low.

Which relation is a function?
Given f(x) = x³ + kx + 13, and the remainder when f(x) is divided by x + 1 is
22, then what is the value of k
The value of k = -10 in f(x).
What is polynomial?Algebraic expressions called polynomials include coefficients and variables. Indeterminates are another name for variables. For polynomial expressions, we can do mathematical operations like addition, subtraction, multiplication, and positive integer exponents but not division by variables.
What is remainder?The amount "left over" after a calculation is the remainder. The integer that remains after multiplying one integer by another to create an integer quotient is known as the remnant in mathematics.
Given that,
f(x) = x³ + kx + 13
The remainder when f(x) is divided by x + 1 is 22,
Here, the f(x) is divided by x+1
Hence, x = -1
Substitute x = -1 in f(x)
22 = f(x) = x³ + kx + 13
22 = f(-1) = (-1)³ + k(-1) + 13
22 = -1 –k +13
22 = -k +12
K = -10
Therefore, the value of k = -10 in f(x).

Lorraine prepared a 2.5-gallon pot filled with tomatoes to be canned in jars. Each jar will hold 1.25 quarts of tomatoes. If 1 gallon equals 4 quarts, how many jars can Lorraine fill?
By using conversion factor, if Lorraine prepared a 2.5 gallon pot filled with tomatoes to be canned in jars and each jar will hold 1.25 quarts of tomatoes, then Lorraine can fill 8 jars
The quantity of tomatoes prepared by Lorraine = 2.5 gallon
The quantity of tomatoes can be filled in one jar = 1.25 quarts
We know
1 gallon = 4 quarts
First convert the quantity of tomatoes prepared by Lorraine from gallon to quarts
2.5 gallon = 2.5×4 = 10 quarts
How many jars can Lorraine fill = The quantity of tomatoes prepared by Lorraine/The quantity of tomatoes can be filled in one jar
we have to use division
= 10/1.25
= 8 jars
Hence, if Lorraine prepared a 2.5 gallon pot filled with tomatoes to be canned in jars and each jar will hold 1.25 quarts of tomatoes, then Lorraine can fill 8 jars

DEEPER The scales shown are used to compare the weights of apples, tangerines, grapefruits, and bananas. How many tangerines
will balance one apple?
Justify your answer using a linear system. Let the weights of apples, tangerines, grapefruits, and bananas be represented by a, t,
g, and b respectively.
Equation for first picture:
Equation for second picture:
Equation for third picture:
Using a system of equations, it is found that 4 tangerines will balance one apple.
The equations are given as follows:
First balance: a + t = g.Second balance: b + t = a.Third balance: 2g = 3b.What is a system of equations?A system of equations is when multiple variables are related, and equations are built to find the numeric values of each variable, according to the relations built in the problem.
For this problem, the variables are given as follows, considering the situation described:
Variable a: weight of an apple.Variable t: weight of a tangerine.Variable g: weight of an grapefruit.Variable b: weight of an banana.For the first picture, one apple and one tangerine balance one grapefruit, hence:
a + t = g.
For the second picture, one banana and one tangerine balance one apple, hence:
b + t = a.
For the third picture, two grapefruits balance three bananas, hence:
2g = 3b.
g = 1.5b.
Replacing on the first equation, we have that:
a + t = 1.5b.
From the second equation, we have that:
b = a - t.
Hence, replacing on the first:
a + t = 1.5(a - t)
1.5a - 1.5t = a + t
0.5a = 2t
a = 4t
Hence 4 tangerines will balance one apple.

Step-by-step explanation:
[tex]x^{2} +13x + 42 = 0\\D = b^{2} - 4ac = 169 - 4*42 = 169 - 168 = 1\\x_{1} = (-13 + 1)/2 = -6\\x_{2} = (-13 -1)/2 = -7\\\\So, x^{2} + 13x + 42 = (x+6)(x+7) \\\\\\[/tex]
Hence, the possible dimensions are x+6 and x+7.
Answer: (x + 6) and (x + 7)
Step-by-step explanation: Determine if the polynomial terms contain a common factor. In this case, there's no common factor. Next, find two numbers whose product is 42 and whose sum is 13. The only pair of numbers that satisfies these conditions is 6 and 7. Finally, write the polynomial in factored form as (x + 6)(x + 7). Therefore, the possible dimensions of the rectangle are (x + 6) by (x + 7).

Which two lines are parallel?
The point (10, y) also lies on line A.
What number does y stand for?
The point (x, 21) also lies on line B.
What number does x stand for?
a. The slopes of lines C and B are the same, therefore, they are parallel.
b. y = 30
c. x = 11
How to Find the Slope of a Line?The slope of a line (m) = change in y/change in x.
Two lines having the same slope (m) value means they are parallel to each other.
a. Slope of line A = change in y/change in x = (9 - 0)/(3 - 0) = 9/3
Slope of line A = 3
Slope of line B = (15 - 1)/(8 - 1) = 14/7
Slope of line B = 2
Slope of line C = (21 - 3)/(12 - 3) = 18/9
Slope of line C = 2
Slope of line D = change in y/change in x = (14 - 2)/(9 - 1) = 12/8
Slope of line D = 3/2
Lines C and B have the same slope, therefore they are parallel.
b. 3 = (9 - y)/(3 - 10)
3 = (9 - y)/-7
-21 = 9 - y
-21 - 9 = -y
-30 = -y
y = 30
c. 2 = (15 - 21)/(8 - x)
2 = -6/(8 - x)
2(8 - x) = -6

Element X decays radioactively with a half life of 13 minutes. If there are 430 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 6 grams?
Using an exponential function, it is found that it would take 80.12 minutes for the element to decay to 6 grams.
What is an exponential function?An exponential function is defined according to the following rule:
[tex]y = a(b)^{\frac{t}{n}}[/tex]
In which:
a is the initial value of the function.b is the rate of change of the function.n is the time in which the rate of change occurs.Considering the half life of the substance, and the initial amount of 430 grams, the parameters are given as follows:
a = 430, b = 0.5, n = 13.
Then the amount of the substance after t minutes is given by:
[tex]y = 430(0.5)^{\frac{t}{13}}[/tex]
The time it will take for the element to 6 grams is t when y = 6, hence:
[tex]6 = 430(0.5)^{\frac{t}{13}}[/tex]

is the median and mean equal? if not which is greater, explain your reasoning
Answer: The median and mean of height of students is not equal, the median is greater.
Step-by-step explanation:
Definition of Median:
Median is the middle value in the picture. To find the median, order the numbers and see which one is in the middle value of the list.
in this picture, first, we order the numbers in numerical order:
1,1,1,2,2,3,3,5,6,6
Find the middle number:
1,1,1,2,2,3,3,5,6,6
As above, 3 is the middle number, then we find which bar represents the median of height of students:
1+1+1+2+2+3 = 10 students
Referring back to the chart, if we add the first 2 bars together, we will get 6+2 = 8 students, but the median number is 10 students, that means the median will be at the third bar, median of height of students = 62-64.
Definition of Mean:
Mean is the sum of the numbers divided by the number of numbers.
In this picture, the Mean will be
(2+6+5+6+3+3+2+1+1+1) / 10
= 3 students
which means the mean height of students = 60-62.

Stephen subtracts 3.48 from 154.2 and gets an answer of 119.4. Use estimation to explain how you know Stephen's answer is incorrect. Then, explain a strategy Stephen could use to solve this problem.
1. Using estimation shows that Stephen's answer is incorrect because when the whole number 3 is subtracted from 154, it gives 151 and not 119. The actual result should be between 150 and 151.
2. The strategy that Stephen could use to solve this subtraction problem is an approximation. Approximately, 3.48 is 3.5, but for a quick estimation, the decimals are eliminated or appropriated.
What is estimation?Estimation means a rough calculation or an approximation.
Estimation provides a quick means of arriving at number solutions without going into detailed calculations.
Estimates are used for decision-making when complete information is not required or available.
The minuend = 154.2
The subtrahend = 3.48
The estimated value of the minuend reduces it to 154.
The estimated value of the subtrahend reduces it to 3.
Using estimation, the difference = 151 (154 - 3)
Actual difference = 150.72 (154.2 - 3.48)
The actual difference can be approximated to 151.
Thus, using appropriate estimation, Stephen can easily solve this subtraction problem without difficulty.

Under these conditions, what is the maximum possible income per day, and what price per pack of cards will produce this income? Include how much extra money is made with this new price structure.
From the statement, we know that:
0. the company sells 1000 packs of cards per day for $5 per pack,
,1. with every $0.02 reduction in price, 10 more packs a day are sold.
To solve this problem, we define the following variables and functions:
• r = # of price reductions,
• n(r) = # of packs sold by the company as a function of r,
,• p(r) = price per pack (in $) as a function of the # of price reductions,
,• I(r) = income (in $) as a function of the # of price reductions.
Using points 1 and 2, we write the following functions: function of # of packs sold n(r) as:

Using it's concept, the probabilities are given as follows:
a) Type A die and orange: 1/10 = 0.1.
b) Blue: 23/30
c) Type B, if blue: 8/23.
What is a probability?A probability is calculated as the number of desired outcomes in the experiment divided by the number of total outcomes in the experiment.
For item a, the probability that a type A dice is chosen is:
3/5.
As there are 5 dices, 3 of type A and 2 of type B.
The probability that a type A dice comes up orange is:
1/6.
As it has six faces, one of which is orange.
Then the probability of an orange type A dice being chosen is:
3/5 x 1/6 = 1/10 = 0.1.
For item b, the probability of blue is divided as follows:
5/6 of 3/5 -> type A.4/6 of 2/5 -> type B.Hence the probability of a blue dice is:
p = 5/6 x 3/5 + 4/6 x 2/5 = 23/30
For item c, we apply the conditional probability, hence the probability is given as follows:
p = (4/6 x 2/5)/(23/30) = (8/30)/(23/30) = 8/23.
Dividing the probabilities of type B and blue by the probability of blue.

Option C is correct.
The equation has infinitely many solutions.
Explanation
To know the nature of the solutions, we need to solve the given equation
