Question:A builder is buying property where she can build new houses. The line plot shows the sizes for each house. 1/6 has 6 X's 1/3 has 3 X's and 1/2 has 6 X's. Organize the information in a line plot. What is the average size of the lots? _________ acre
Help anyone?
Solution:
We are asked to organize the information in a line plot. See attachment for the line plot.
Given: 1/6 has 6 X's 1/3 has 3 X's and 1/2 has 6 X'sIn no particular order, the sizes of the lots are:1/6, 1/6, 1/6, 1/6, 1/6, 1/6, 1/3, 1/3, 1/3, 1/2, 1/2, 1/2, 1/2, 1/2 and 1/2 acre.
Let's count the number of lot for each size given.
For 1/6: there are 6 X's on the line plot of 1/6 number of lot for 1/6
= the lot × number of times it occurs
= (1/6) × 6 = 6/6 = 1 acre
For 1/3: there are 3 X's on the line plot of 1/3 number of lot for 1/3 = the lot × number of times it occurs
= (1/3) × 3 = 3/3 = 1 acre
For 1/2: there are 6 X's on the line plot of 1/2 number of lot for 1/2
= the lot × number of times it occurs
= (1/2) × 6 = 6/2= 3 acres
To find average size of the lots, we would sum all lot for each given size then divide by the total number of lots given.Sum of all lot for each given size = 1+1+3
Sum of all lot for each given size = 5
The total number of lots given = 15
Average size of the lots = 5/15 = 1/3
Average size of the lots = ⅓ acre

The parallelogram shown below has an area of 140140140 units^2 2 squared. Find the missing base. b =b=b, equals units
Answers
Answer:
Length of the base of the given parallelogram is 14 units
Step-by-step explanation:
This question is incomplete; Find the complete question in the attachment.
Area of the parallelogram (A) = 140 square units
Height of the parallelogram (h) = 10 units
Since area of the parallelogram = Base × height
A = b × h
140 = b × 10
b = [tex]\frac{140}{10}[/tex]
b = 14 units
Therefore, length of the base of the given parallelogram is 14 units.

14 units is the answer I got it right on khan academy.
if a square+ b square+ c square=90, a+b+c=20 find the value of ab+bc+ca
Answers
Answer: ab + bc + ac = 155
Step-by-step explanation:
Given: a² + b² + c² = 90 and a + b + c = 20
Square the second equation, subtract it from the first equation, then simplify.
Square the second equation:
(a + b + c)² = 20²
a² + b² + c² + 2ab + 2bc + 2ac = 400
Subtract the equations:
a² + b² + c² + 2ab + 2bc + 2ac = 400
- (a² + b² + c² = 90)
2ab + 2bc + 2ac = 310
Simplify:
2(ab + bc + ac) = 310
÷2 ÷2
ab + bc + ac = 155

Answers
Answer:
x ≈ - 0.7 ≈ 0.7; Option A
Step-by-step explanation:
Let us substitute f ( x ) with 0, as to find the " real zero value( s ) " of the function;
0 = 3x^4 + x^2 - 1 ⇒ Swap sides, as such,
3x^4 + x^2 - 1 = 0 ⇒ Rewrite equation with u being = x^2, u^2 = x^2,
3u^2 + u - 1 = 0 ⇒ And solve for u by completing the square,
3u^2 + u = 1 ⇒ Divide either side by 3,
u^2 + u / 3 = 1 / 3 ⇒ Write equation in the form x^2 + 2ax + a^2 = ( x + a )^2, solving for a,
2au = 1 / 3u,
a = ( 1 / 3u ) / 2u,
a = 1 / 6 ⇒ Add value of a^2 to either side of equation,
u^2 + u / 3 + ( 1 / 6 )^2 = 13 / 36,
( u + 1/ 6 )^2 = 13 / 36 ⇒ Solve for u,
u = ( √13 - 1 ) / 6, and u = ( - √13 - 1 ) / 6 ⇒ Substitute value of u back into first equation to solve for x,
x = √( - 1 + √13 ) / 6 ), x = - √( - 1 + √13 ) / 6 ), x = √( - 1 - √13 ) / 6 ), x = - √( - 1 - √13 ) / 6 ) ⇒ Convert to approximate decimal form,
x = 0.6589.... = - 0.6589....
Answer; x ≈ - 0.7 ≈ 0.7; Option A
What is the measure of the unknown angle?
A. 60°
B. 63°
C. 64°
D. 70°
Answers
Answer:
B. 63°
Step-by-step explanation:
The distance around a circle is 360°
This means that 297° + n = 360°
Equation:
297 + n = 360
We can find the value of n by subtracting:
297 + n = 360
-297 -297
n = 63
Therefore, the value of n is 63 degrees.

Answers
Answer:

Covered length = 2/5
Remaining length = 5/5 - 2/5 = 3/5
If 3/5 = 60 km
What about 5/5 = ?

Q 5) No. of boys = 20
Answer:
Q 6) Total time taken to answer both the quizzes = 90 minutes
Step-by-step explanation:
Q 5.
Let the number of boys = x
Therefore, number of girls = x - 5
Since,
No. of boys + No. of girls = 35
hence,
x + x- 5 = 35
2x-5 = 35
2x = 35 + 5
2x = 40
x = 40/2
x = 20
Hence 20 boys participated in the activity.
Let the time taken to answer history quiz= x min
Therefore, time taken to answer geography quiz = (x + 30) min
According to the given information:
x = 1/2(x + 30)
2x = x + 30
2x - x = 30
x = 30 min
Hence, x + 30 = 30 + 30 = 60 min
Total time taken to answer both the quizzes = 30 + 60 = 90 minutes

Step-by-step explanation:

Q1: 9

Median: 11
Range: 19 - 7 = 12
25% percentile: 9
75% percentile: 14
IQR: 14 - 9 = 5
Step-by-step explanation:
Step 1: Find the median
The median on the box-and-whisker plot is the line that is inside of the box. On this plot, the median is 11 since it is where the line is.
Step 2: Find the range
The range on a box-and-whisker plot is the difference from the largest point and the smallest point. On this plot, the largest point is 19 and the smallest point is 7. So, subtract 7 from 19 and you get that the range is 12.
Step 3: Find the 25th percentile
The 25th percentile on a box-and-whisker plot is the left side of the box object. On this plot, the 25th percentile is 9.
Step 4: Find the 75th percentile
The 75th percentile on a box-and-whisker plot is the right side of the box object. On this plot, the 75th percentile is 14.
Step 5: Find the inter-quartile range
The inter-quartile range on a box-and-whisker plot is the difference between the 75th percentile or right side of the box and the 25th percentile or the left side of the box. On this plot, the 75th percentile is 14 and the 25th percentile is 9. So, subtract 9 from 14 and you get that the inter-quartile range is 5.
Point b has coordinates (-8,15) and lies on the circle whose equation is x^2+y^2=289. If an angles is drawn in standard position with its terminal ray extending through point b, what is the cosine of the angle?
Answers
Answer:
[tex]\cos \theta=-\dfrac{8}{17}[/tex]
Step-by-step explanation:
Coordinates of Point b[tex]=(-8,15)[/tex]
b lies on the circle whose equation is [tex]x^2+y^2=289[/tex]
[tex]x^2+y^2=17^2[/tex]
Comparing with the general form a circle with center at the origin: [tex]x^2+y^2=r^2[/tex]
The radius of the circle =17 which is the length of the hypotenuse of the terminal ray through point b.
For an angle drawn in standard position through point b,
x=-8 which is negative
y=15 which is positive
Therefore, the angle is in Quadrant II.
[tex]\cos \theta=\dfrac{Adjacent}{Hypotenuse} \\$Adjacent=-8\\Hypotenuse=17\\\cos \theta=\dfrac{-8}{17} \\\cos \theta=-\dfrac{8}{17}[/tex]

Answers
Answer:
D. He distributed Negative one-fourth over (8 x + 12), distributed –1 over (Negative 2 x + 5), and then combined like terms.
Step-by-step explanation:
We know that when using the distributive property, you have to multiply the outside value with the inside value and then either subtract or add.
You can combine like terms first, but that is only if there are like terms inside the parentheses. In this case, there are not, so you would distribute first.
So, to do that, you have to first distribute -1/4 to the 8x+12 and then distribute the -1 to the -2x+5. (note that they did not include the 1, but it is still there)
So, it is D

Answer:
[-1,3) domain i think the video i am watching kinda confusing tell me if i am right
[3,-5) range like i said tell me i got it wrong
Step-by-step explanation:
The domain and the range of a graph is the possible x and y values, the graph can take.
The domain of the function is: [tex]-1 \le x < 3[/tex] .The range of the function is: [tex]3 \ge y > -5[/tex]First, we determine the domain.
On the x-axis, the curve starts from x = -1 with a closed circle, and it ends at x = 3, with an open circle
A closed circle is represented by [tex]\ge[/tex] or [tex]\le[/tex], while an open circle is represented > or <
So, the domain of the graph is: [tex]-1 \le x < 3[/tex]
Next, we determine the range.
On the y-axis, the curve starts from y = 3 with a closed circle, and it ends at y = -5, with an open circle
Using the explanation of open and closed circle above,
The range of the function is: [tex]3 \ge y > -5[/tex]
Hence, the domain and the range of the graph are: [tex]-1 \le x < 3[/tex] and [tex]3 \ge y > -5[/tex], respectively.
