Answer:
Since this function is definable for all real values of x,
Domain(f(x)) = R = (-∞,∞)
Step-by-step explanation:
Now,
Let 4x-8=y
4x = y+8
x = (y+8)/4
Since x is definable for all real values of y,
Range(f(x)) = R = (-∞,∞)

Calculate the answer to the correct number of significant figures: 41.70 + 0.506 + 0.00223 = ______.
42.20823
42.2082
42.208

42.21
The answer to the correct number of significant figures is 42.21
Addition of decimal numbersWhen adding decimal numbers, the number of significance of the resulting value will be to the least decimal numbers in the given expression.
Given the sum of decimal shown
41.70 + 0.506 + 0.00223
Using the calculator to take the sum
41.70 + 0.506 + 0.00223 = 42.20823
Since the significance value in the expression is 4, hence we will round the result to 4sf to have 42.21

Find The Surface Area Of The Prism
Answer:
190cm²
Step-by-step explanation:
there is 2 types of sides on this. the top and bottom are the same, the front, back, left, and right are the same.
We first calculate the surface area of the top and bottom.
5x5=25
now we multiply that by 2 because the top and bottom are the same
25x2=50
now we look at the remaining 4 sides. the sides on these are 7 and 5 so we do
7×5=35
since we have 4 sides, we multiply the answer by 4
4×35=140
we add the sums together
140+50=190cm²
Answer:
190 cm^2
Step-by-step explanation:
The formula for the surface area of a rectangular prism is:
2 (lw + hl + hw)
Use the formula with the given dimensions of the prism:
2 (5 x 5) + (7 x 5) + (7 x 5)
= 2 (25 + 35 + 35)
= 2 (95)
= 190
So the SA of the rectangular prism is 190 cm^2

an ice fisherman wishes to cut a hole in the ice which has a diameter of 30 cm. How far around must he cut to create this hole?
Given:
Diameter of the hole = 30 cm
To find:
The area of the hole.
Solution:
The radius of a circle is always half of the diameter. It is given that the diameter of the hole is 30 cm. So, the radius of the hole is:
[tex]r=\dfrac{30}{2}[/tex]
[tex]r=15[/tex]
Area of a circle is:
[tex]A=\pi r^2[/tex]
Putting [tex]\pi = 3.14[/tex] and [tex]r=15[/tex] in the above formula, we get
[tex]A=(3.14)(15)^2[/tex]
[tex]A=(3.14)(225)[/tex]
[tex]A=706.5[/tex]
Therefore, the area of the hold is 706.5 square cm.
In a class test, (+2) marks were given for every correct answer and (–1) mark was
deducted for every incorrect answer. Rashmi answered all the questions and scored 30
marks. She gave 20 correct answers. Jashpal also answered a few questions and scored
–10 marks. He gave 5 correct answers. How many questions did Rashmi and Jashpal
attempt incorrectly?
Answer:
Rashmi attempted 10 questions incorrectly while Jashpal attempted 20 questions incorrectly
Step-by-step explanation:
Marks awarded for each correct answers = +2
Marks deducted each incorrect answer = -1
The number of questions Rashmi answered = All the question
Rashmi's score = 30
The correct answers Rashmi gave = 20
The number of questions Jashpal answered = A few questions
Jaspal's score = -10 marks
The number of correct questions Jashpal answered = 5
Let x represent the number of incorrect questions, for Rashmi, we have;
20×2 + x × (-1) = 30
x = 20×2 - 30 = 10
The number of questions Rasmi attempted incorrectly, x = 10
The number of questions Jashpal attempted incorrectly is given as follows;
5×2 + x × (-1) = -10
∴ 10 - x = -10
x = 10 + 10 = 20
The number of questions Jashpal attempted incorrectly, x = 20.

Answer:
5/6
Step-by-step explanation:
The outcome of a die is 1,2,3,4,5,6
Even = 2,4,6
Less than 4 = 1,2,3
Good outcomes = 1,2,3,4,6 = 5 valid outcomes
P( even or less than 4) = valid outcomes / total
=5/6
Answer:
1/4
Step-by-step explanation:
total outcome=6
p(even)=3/6=1/2
p(less than 4)=3/6=1/2
p(even or less than 4)=1/2×1/2=1/4

what is the slope of a line perpendicular to y=-(7)/(4)x
Answer: 4/7
This is because the original line has slope -7/4. We flip the fraction and the sign, ie take the negative reciprocal, to get the perpendicular slope.
Flipping the fraction goes from -7/4 to -4/7. Then it flips to positive to get 4/7
Notice that multiplying the original and perpendicular slopes together gets us -1
(-7/4)*(4/7) = -1
This applies to any pair of perpendicular lines as long as neither line is vertical and neither is horizontal.
Answer:
[tex]\frac{4}{7}[/tex]
Step-by-step explanation:
Given
y = - [tex]\frac{7}{4}[/tex] x ( in the form y = mx , where m is the slope )
slope m = - [tex]\frac{7}{4}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{7}{4} }[/tex] = [tex]\frac{4}{7}[/tex]

The two dot plots below show the heights of some sixth graders and some seventh graders: The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 1.7. Approximately how many times the variability in the heights of the sixth graders is the variability in the heights of the seventh graders
Answer:
The number of times the variability in the heights of the sixth graders is the variability in the heights of the seventh graders is approximately 1.4
Step-by-step explanation:
From the question, the mean absolute deviation (MAD) of the sixth graders = 1.2 and that of the seventh graders = 1.7
The variability in the heights of the sixth graders = 1.2
The variability in the heights of the seventh graders = 1.7
To calculate how many times the variability in the heights of the sixth graders is the variability in the heights of the seventh graders, we will divide the variability of the seventh graders by the variability of the sixth graders
That is, 1.7/ 1.2 = 1.4167 ≅ 1.4
Hence, the number of times the variability in the heights of the sixth graders is the variability in the heights of the seventh graders is approximately 1.4
