Solve the proportion.
x+1/×-1 = 14/20
A: - 3/17
B: 10/7
C: 7/10
D: -17/3
14x+14=20x-20
-6x=-34
x=34/6=-17/3
D: -17/3
Answer:
D
Step-by-step explanation:
x+1/x-1=14/20
so 20(x+1)=14(x-1)
20x+20=14x-14
20x-14x= -14-20
6x=-34
so x=-17/3

Millions of students take statistics each year! Researchers hoping to help professors teach better conducted a study in statistics classrooms. They had the same instructor teach three different classes, with randomly assigned students, with three different methods! Method A - traditional lectures, with homework outside of class. Method B - flipped classroom, with students watching videos of lectures and working on homework in class with peers and instructor. Method C - fully online, with students watching videos of lectures, with homework outside of class. They then gave each class the same final exam (out of 20 points). These were the results:

find the gretest number which devded by 181 and 236 leave a remainder of 5 in each case
Answer:
The greatest number is 11
Step-by-step explanation:
Given
Dividends: 181 and 236
Remainder: 5
Required
Determine a divisor that satisfies the above condition
Let the required divisor be represented with x.
Since a remainder of 5 is expected, then x can divide (181 - 5) and (236 - 5) without remainders.
So, we have:
[tex]181 - 5 = 176[/tex]
[tex]236 - 5 = 231[/tex]
Next, we calculate the GCF of 176 and 231
[tex]176 = 2 * 2 * 2 * 2 * 11[/tex]
[tex]231 = 3 * 7 * 11[/tex]
The greatest common factor, GCT is:
[tex]GCF = 11[/tex]
Hence, the required divisor is 11

What is the answer for this math problem
Answer:
The group of all ordered pairs lie on the line is (3, 7), (2, 6), (-2, 2) ⇒ D
Step-by-step explanation:
To solve this type of question, Form the equation of the line and substitute the x-coordinate of each ordered pair to find y, if the value of y equal to the value of the y-coordinate of the point, then the point is on the line
The form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-intercept (value y at x = 0The rule of the slope of the line that passes through points (x1, y1) and (x2, y2) is m = [tex]\frac{y2-y1}{x2-x1}[/tex]From the given figure
∵ The line passes through points (-4, 0) and (0, 4)
∴ x1 = -4 and y1 = 0
∴ x2 = 0 and y2 = 4
→ Substitute them in the rule above
∵ m = [tex]\frac{4-0}{0--4}[/tex] = [tex]\frac{4}{0+4}[/tex] = [tex]\frac{4}{4}[/tex]
∴ m = 1
∵ b is the value of y at x = 0
∵ y = 4 at x = 0
∴ b = 4
→ Substitute the values of m and b in the form of the equation above
∴ y = 1(x) + 4
∴ y = x + 4 ⇒ equation of the given line
Let us check every group
∵ The ordered pairs are (7, 3), (6, 2), (2, -2)
∵ y = x + 4
∵ x = 7
∵ y = 7 + 4 = 11
∵ y-coordinate = 3
∴ Point (7, 3) doesn't lie on the line
∵ The ordered pairs are (5, 1), (3, 7), (2, 6)
∵ x = 5
∴ y = 5 + 4 = 9
∵ y-coordinate = 1
∴ Point (5, 1) doesn't lie on the line
∵ The ordered pairs are (3, 7), (2, 6), (2, 2)
∵ x = 3
∴ y = 3 + 4 = 7
∵ y-coordinate = 7
∴ Point (3, 7) lies on the line
∵ x = 2
∴ y = 2 + 4 = 6
∵ y-coordinate = 6
∴ Point (2, 6) lies on the line
∵ x = 2
∴ y = 6
∵ y-coordinate = 2
∴ Point (2, 2) doesn't lie on the line
∵ The ordered pairs are (3, 7), (2, 6), (-2, 2)
∵ x = 3
∴ y = 3 + 4 = 7
∵ y-coordinate = 7
∴ Point (3, 7) lies on the line
∵ x = 2
∴ y = 2 + 4 = 6
∵ y-coordinate = 6
∴ Point (2, 6) lies on the line
∵ x = -2
∴ y = -2 + 4 = 2
∵ y-coordinate = 2
∴ Point (-2, 2) lies on the line
∵ The three ordered pairs lie on the line
∴ The group of all ordered pairs lie on the line is (3, 7), (2, 6), (-2, 2)
∵ The ordered pairs are (1, 5), (-6, 2), (-7, -3)
∵ x = 1
∴ y = 1 + 4 = 5
∵ y-coordinate = 5
∴ Point (1, 5) lies on the line
∵ x = -6
∴ y = -6 + 4 = -2
∵ y-coordinate = 2
∴ Point (-6, 2) doesn't lie on the line

Answer:
m∠ADC = 86°
Step-by-step explanation:
The sum of angles making a straight angle is 180°, so we have ...
(6x +52)° +(9x +23)° = 180°
15x = 105 . . . . . subtract 75°, collect terms, divide by °
x = 7 . . . . . . . . . divide by 15
m∠ADC = (9·7 +23)°
m∠ADC = 86°
Here given that ,
Line BDA is a straight line Angles on the line BDA are ∠BDC & ∠ADCAs we know that , sum of angles on a straight line is always equal to 180° . So ,
=> ( 6x + 52 ) ° + ( 9x + 23 ) ° = 180°
=> 15x + 75° = 180°
=> 15x = 180° - 75°
=> 15x = 105°
=> x = 105°/15
=> x = 7°
Now , by the given information , we need to find the value of ∠ADC
∠ADC = ( 9x + 23 ) °Now substituting the value of x ,
⇒ ∠ADC = 9x + 23
⇒ ∠ADC = 9 ( 7 ) + 23
⇒ ∠ADC = 63 + 23
⇒ ∠ADC = 86°

Answer: y int = -1.5
Slope = -1/4
Step-by-step explanation: y int is the point at which the line cross the y axis.
Slope = rise/run
Starting from the point on the left of the graph (-6,0) and going the the other point (2, -2) you can see the it rises -2 point. (0 to -2) the it runs 8 point. (-6 to 2).
Therefore the Slope = -2/8 or -1/4
Many ancient tombs were cut from limestone rock that contained uranium. Since most such tombs are not well-ventilated, they may contain radon gas. In one study, the radon levels in a sample of 12 tombs in a particular region were measured in becquerels per cubic meter (Bq/m3). For this data, assume that x(over-bar)= 3,469 Bq/m3 and s= 1,135 Bq/m3. Use this information to estimate, with 95% confidence, the mean level of radon exposure in tombs in the region. Interpret the resulting interval.
Answer:
95% confidence interval of the mean level of random exposure in tombs in the region.
(2746.868 , 4191.132)
Step-by-step explanation:
Step(i):-
Given sample size 'n'= 12
Mean of the sample x⁻ = 3,469
and standard deviation of the sample 's' = 1,135
95% confidence intervals are determined by
[tex](x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} +t_{0.05} \frac{S}{\sqrt{n} } )[/tex]
Degrees of freedom = n-1 = 12-1= 11
Step(ii):-
95% confidence intervals are determined by
[tex](3469- 2.201 \frac{1135}{\sqrt{12} } , 3469+2.201\frac{1135}{\sqrt{12} } )[/tex]
( 3469-722.132 , 3469 +722.132)
