Answer:
well 6/20 has more absolute value than 7/30
Step-by-step explanation:
also 7/30 is closer to zero
Comparison of 30% has more absolute value than 23.3%
What is percentage?Percentage is defined as ratio expressed as a fraction of 100.
Let x = 6 broken bulbs out of 20
y = 7 broken bulbs out of 30
x = 6/20
x = 0.3
There are 30% bulbs broken out of 20
y = 7/30
y = 0.233
There are 23.3% bulbs broken out of 20
Hence, 30% has more absolute value than 23.3%

what is the midpoint of the line segment with endpoints (3.2,2.5) and (1.6,-4.5)?
Answer:
Midpoint: (2.4, -1)
Step-by-step explanation:
Midpoint Formula: [tex](\frac{x1+x2}{2} , \frac{y1+y2}{2} )[/tex]
With that in mind,
(3.2 + 1.6)/2 = 2.4
(2.5 - 4.5)/2 = -1
Answer:
(2.4, -1)
Step-by-step explanation:
To find the x coordinate of the midpoint, average the x coordinates
(3.2+1.6)/2 = 4.8/2 = 2.4
To find the y coordinate of the midpoint, average the y coordinates
(2.5+-4.5)/2 = -2/2 = -1
(2.4, -1)
what are the two consecutive numbers of 235
Answer:
117, 118
Step-by-step explanation:
if 2 consecutive numbers have a sum of 235, then
Let the 2 numbers be n and n+1
Given That:
n + n+1 = 235
Simplify and solve:
2n + 1 - 235
2n = 234
n = 117.
If n = 117, then n +1 = 118. These are the 2 consecutive numbers.
Hope this helps.

For speed skaters, Marco, Naim, and Pedro, compete in a relay race where they all agree Naim will be the last skater. Then they try to decide whether or not all of her should be the first skater in the race. Which subset, A, Of the sample space shows the complement of the event in which Oliver is the first skater in the race.
Answer:
A = {MOPN, MPON, PMON, POMN}
Step-by-step explanation:
Everybody has already decided that Naim is the last skater, so we need to make sure the result is 'N' in each last position. As we can see all of them have this.
However, we just need to make sure that Oliver doesn't first, because even if they're attempting to decide, the question is calling for the inclusion in which "Oliver is the very first skater in the race."
A complement is all the NOT values in the package or set, so it cannot be either A = {OPMN, OMPN) or A = {MOPN,MPON, OPMN, POMN), since all of them have at minimum one case where 'O' is first.
A complement is ALL other values of the set, and it can not be A = {MOPN, PMON}, since only two possible values are included in that package or set

The population, P in thousands of a resort community is shown by
P(t)= 500t/2t^2+9'
where t is the time in months since city council raised property taxes.
Find the interval on which the population was 40,000 or greater
Answer:
t ≤ 4.24
Step-by-step explanation:
P(t) ≥ 40000 implies
500t/(2t²+9) ≥ 40000
Multiplying through by t², we have
500t ≥ 40000(2t²+9)
500t/40000 ≥ 2t²+9
Collecting like terms
0.0125t ≥ 2t²+9
0 ≥ 2t²+ 9 - 0.0125t
2t²+ 9 - 0.0125t ≤ 0
2t²- 0.0125t + 9 ≤ 0
Using the quadratic formula,
[tex]t = \frac{-(-0.0125) +/-\sqrt{(-.0125)^{2} - 4 X 2 X 9} }{2 X 2} \\= \frac{0.0125 +/-\sqrt{(0.00015625 - 288} }{4}\\= \frac{0.0125 +/-\sqrt{-287.9998} }{4}\\= \frac{0.0125 +/-16.97i }{4}\\=0.00313 + 4.24i or 0.00313 - 4.24i[/tex]
The factors of the equation are (t - 0.00313 -4.24i) and (t - 0.00313 + 4.24i)
So, (t - 0.00313 -4.24i)(t - 0.00313 + 4.24i) ≤ 0
(t - 0.00313)² - 4.24² ≤ 0
(t - 0.00313)² ≤ 4.24²
taking square-root of both sides,
√(t - 0.00313)² ≤ √4.24²
t - 0.00313 ≤ 4.24
t ≤ 4.24 + 0.00313
t ≤ 4.24313 ≅ 4.24
t ≤ 4.24

A company makes 140 bags.
47 of the bags have buttons but no zips.
48 of the bags have zips but no buttons.
22 of the bags have neither zips nor buttons.
A bag is selected at random.
What is the probability that the bag has buttons
Answer: 0.5
Step-by-step explanation:
Total bags (U) = 140
Number of bags with both button and zip:
(48 + 47 + x + 22) = 140
117 + x = 140
x = 140 - 117
x = 23
Therefore, probability that bag has button :
Total Number of bags with button:
(Bags with button alone + bags with both button and zip)
(47 + 23) = 70
Probability = (required outcome / Total possible outcomes)
P(bag has button) = (number of bags with button / total number of bags)
P(bag has button) = 70/140 = 0.5
P(bag has button) = 0.5

Jose asks his friends to guess the higher of two grades he received on his math tests. He gives them two hints. The difference of the two grades is 16. The sum of one-eighth of the higher grade and one-half of the lower grade is 52. The system that represents his scores is below. x – y = 16 StartFraction 1 over 8 EndFraction x plus StartFraction one-half EndFraction y equals 52.x + StartFraction one-half EndFraction x plus StartFraction one-half EndFraction y equals 18.y = 52 What is the higher grade of Jose’s two tests?
Answer : 96
x – y = 16 --------> equation 1
1/8 x + 1/2 y = 52
x is the higher grade and y is the lower grade
We solve the first equation for y
x - y = 16
-y = 16 -x ( divide each term by -1)
y = -16 + x
Now substitute y in second equation
1/8 x + 1/2 ( -16 + x ) = 52
1/8x - 8 + 1/2 x = 52
1/8x + 1/2x - 8 = 52
Take common denominator to combine fractions
1/8x + 4/8x -8 = 52
5/8x - 8 = 52
Add 8 on both sides
5/8x = 60
Multiply both sides by 8/5
x = 96
We know x is the higher grade
96 is the higher grade of Jose’s two tests.
The higher grade and lower grade of Jose’s two tests will be 96 and 80.
What is the solution of the equation?The solution of the equation means the value of the unknown or variable.
Jose asks his friends to guess the higher of two grades he received on his math tests.
He gives them two hints.
Let x be the higher number and y be the lower number.
The difference of the two grades is 16.
x - y = 16 ...1
The sum of one-eighth of the higher grade and one-half of the lower grade is 52.
x/8 + y/2 = 52
x + 4y = 416 ...2
Subtract equation 1 from 2, we have
4y + y = 416 – 16
5y = 400
y = 80
Then the value of x will be
x – 80 = 16
x = 80 + 16
x = 96
The higher grade and lower grade of Jose’s two tests will be 96 and 80.

Which of the following equations has both 1 and -3 as solutions?
O x2 - 2x -3 =0
x² + 2X-3 =0
O x2 - 4x +3 =0
O x2 + 4x +3 =0
Answer:
The answer is B.
Step-by-step explanation:
Instead of solving each equation, simply think about it alternatively.
Recall that quadratic equations can also be written as: [tex](x-a)(x-b)[/tex], where [tex]a[/tex] and [tex]b[/tex] are the solutions.
We know that 1 and -3 are solutions, so we can substitute them in for [tex]a[/tex] and [tex]b[/tex].
Thus, we have:
[tex](x-(1))(x-(-3))[/tex]
[tex](x-1)(x+3)[/tex]
Now, expand:
[tex]x^2+3x-x-3[/tex]
[tex]x^2+2x-3[/tex]
The answer is B.
What is the length of side s of the square shown below?
Answer:
3√2
Step-by-step explanation:
Pythagoras says s²+s²=6²
so
2s² = 36
s = √18 = √9·2 = √3²·2 = 3√2
Answer:
C
Step-by-step explanation:
The diagonal splits the square into 2 right triangles with hypotenuse 6
Using Pythagoras' identity in one of the right triangles.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
s² + s² = 6²
2s² = 36 ( divide both sides by 2 )
s² = 18 ( take the square root of both sides )
s = [tex]\sqrt{18}[/tex] = [tex]\sqrt{9(2)}[/tex] = [tex]\sqrt{9}[/tex] × [tex]\sqrt{2}[/tex] = 3[tex]\sqrt{2}[/tex] → C
A producer of electronic book readers is performing a quality check to ensure the reader's backlight is working correctly. The plant manager tests 2,000 readers on Monday and finds that 8 have defective backlights. The fraction StartFraction 1 over x EndFraction is the experimental probability of a book reader having a defective backlight. What is the value of x?
Answer: 25
Step-by-step explanation:
From the question, we are told that a producer of electronic book readers is performing a quality check to make sure that the reader's backlight is working correctly. Then, the plant manager tests 2,000 readers on Monday and finds that 8 have defective backlights. The fraction 1/x is the experimental probability of a book reader having a defective backlight. What is the value of x?
Number of tested readers= 2000
Defective backlight = 8
Probability of having a defective backlight will be the number of defective backlight divided by the number of readers tested. This will be:
= 8/200
We reduce the nice fraction to its lowest term.
8/200 = 1/25
Therefore x will be 25
Answer:
250

Which of the following is the shape of a cross-section of the figure shown below?
Answer:
B. Pentagon
Step-by-step explanation:
A cross-section is basically the 2D figure created by slicing through a 3D shape.
Take a look at this figure: it's a pentagonal prism. One note to remember is that for all prisms, their cross-sectional shapes are the same shapes as the shape of their bases.
Here, the two bases are pentagons, so we know the cross-section will be a pentagon.

Use the slope formula:
m= y2−y1 /x2−x1
= −2−2 /0−−2
= −4 /2
=−2
Answer:
m=−2 This is the slope
So,the slope intercept form for 2 points is y-y1=m(x-x1) m=slope
y-y1=m(x=x1)
y-2=-2(x-(-2) ( - and - is +) So,the final equation is:
