Answer:
Linda earned 2 points on 14 turns.
Step-by-step explanation:
Given that Linda has played 16 turns and has obtained 34 points, taking into account that in each turn she can obtain 2 or 3 points, to determine the number of turns in which she obtained 2 points, the following table must be performed:
-If in 16 turns she obtained 2 points, the total points will be 32
-If in 15 turns she obtained 2 points and in 1 turn she obtained 3 points, the total points will be 33
-If in 14 turns she obtained 2 points and in 2 turns she obtained 3 points, the total of points will be 34
Therefore, Linda scored 2 points in 14 of the 16 turns played.

What is the value of x in inches?
6.6 in.
8.2 in.
22.9 in.
27.1 in.
Answer: 6.6
Step-by-step explanation:
Ayo!!
First you use the formula SF=N/O. The new is the big triangle. The Old is the small triangle. Next you tick the sides of each triangle. So lets say 4.1 will be 1 tick and 2.2 will be 2 ticks. Now the old triangle is done now to the new triangle. 12.3 is the 1 tick and x is the 2 ticks.
Lets set up the formula. N-/N--= O-/O--= 12.3/x and 4.1/2.2. Now u cross multiply. 4.1x=12.3*2.2=4.1x=27.06. Then you divide 4.1x by 4.1 and 27.06 by 4 aswell. 4.1x divided by 4.1 cancel each other out so you are left with 27.06 divided by 4.1 and that equals 6.6. So the answer is 6.6.
PS: If i did the new and old triangles wrong just reverse them and just do it like I explained it.
Hope this helped! :)

Triangle RST is an isosceles triangle.
Triangle RST is a scalene triangle.
Triangle RST is a right triangle.
Triangle RST is an equilateral triangle.
Answer:
RST is an isosceles triangle
Step-by-step explanation:.
Required
Determine what type of triangle, is RST.
First, we need to determine the angles in RST
Angle on a straight line is 180°.
So, if <mTS = 130°
Then,
<STR = 180° - 130°
<STR = 50°
Similarly,
<TSR = 180° - 130°
<TSR = 50°
The sum of angles in a triangle is 180°.
So:
<TSR + <STR + <TRS = 180°
50 + 50 + <TSR = 180°
100 + <TSR = 180°
<TSR = 180° - 100°
<TSR = 80°
Hence, the three angles of the triangle are: 50°, 50° and 80°
When just two angles of a triangle are equal; such triangle is referred to as an isosceles triangle
Hence, option A answers the question.

The claim is that the standard deviation of the speeds of drivers in Bradford is 8 mph. An experienced driver feels that this is very low. If a random speed check is conducted for 50 drivers, the standard deviation is 10.5 mph. Can we reject the null at
Answer:
Null hypothesis is rejected. Standard deviation is > 8 miles per hour
Step-by-step explanation:
σ [Population standard deviation] = 8 , s [sample standard deviation] = s
n [no of items] = 8
H0 [Null] : σ = 8 ; H1 [Alternate - Right Tail] : σ > 8
χ2 = (n - 1) . s^2 / σ^2
= 49 x (10.5)^2 / 82 = 5402.25 / 64
χ2 = 84.410
df [degree of freedom] = n -1 = 50 - 1 = 49
P value (χ^2 49 > 84.410) = 0.00125
p = 0.0013
p < α ie 0.05
So, H0 is rejected
Hence we state that standard deviation is > 8 miles per hpur

Step-by-step explanation:
Suppose g(x) = f(x) + k. Identify a value of k that transforms f into g.
Answer:
[tex]k = 5[/tex]
Step-by-step explanation:
Given
[tex]g(x) = f(x) + k[/tex]
Required
Determine the value of k
First, we need to determine the equation of g(x)
Start by calculating the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where x and y are two corresponding values:
[tex](x_1,y_1) = (1,1)[/tex]
[tex](x_2,y_2) = (0,-3)[/tex]
The slope (m) is:
[tex]m = \frac{-3- 1}{0 - 1}[/tex]
[tex]m = \frac{-4}{- 1}[/tex]
[tex]m = 4[/tex]
The equation is calculated using:
[tex]y - y_1 = m(x - x_1)[/tex]
Where
[tex]m = 4[/tex] and [tex](x_1,y_1) = (1,1)[/tex]
[tex]y - 1 = 4(x - 1)[/tex]
[tex]y - 1 = 4x - 4[/tex]
Make y the subject of formula
[tex]y = 4x - 4 + 1[/tex]
[tex]y = 4x - 3[/tex]
So:
[tex]f(x) = 4x - 3[/tex]
Next, we determine the equation of f(x)
Start by calculating the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where x and y are two corresponding values:
[tex](x_1,y_1) = (-1,-2)[/tex]
[tex](x_2,y_2) = (0,2)[/tex]
The slope (m) is:
[tex]m = \frac{2- (-2)}{0 - (-1)}[/tex]
[tex]m = \frac{2+2}{0+1}[/tex]
[tex]m = \frac{4}{1}[/tex]
[tex]m = 4[/tex]
The equation is calculated using:
[tex]y - y_1 = m(x - x_1)[/tex]
Where
[tex]m = 4[/tex] and [tex](x_1,y_1) = (-1,-2)[/tex]
[tex]y - (-2) = 4(x - (-1))[/tex]
[tex]y + 2 = 4(x +1)[/tex]
[tex]y + 2 = 4x +4[/tex]
Make y the subject of formula
[tex]y = 4x + 4 - 2[/tex]
[tex]y = 4x + 2[/tex]
So:
[tex]g(x) = 4x + 2[/tex]
Recall that
[tex]g(x) = f(x) + k[/tex]
Make k the subject
[tex]k = g(x) - f(x)[/tex]
Substitute values for g(x) and f(x)
[tex]k = 4x + 2 - (4x - 3)[/tex]
[tex]k = 4x + 2 - 4x + 3[/tex]
[tex]k = 4x - 4x+ 2 + 3[/tex]
[tex]k = 5[/tex]
The transformation that maps f into g is a translation transformation,
involving the addition of k to the value of f(x).
The value of k that transforms f into g is; k = -5Reasons:
Points on the graph of g(x) are; (0, -3) and (0, 1)
[tex]\mathrm{The \ slope \ of \ the \ graph \ of \ g(x)} =\dfrac{-3 - 1}{0 - 1} = 4[/tex]
The equation of g(x) is; y - (-3) = 4·x, which gives;
y = 4·x - 3
The y-intercept = -3
Points on the graph of f(x) are; (-1 -2) and (0, 2)
[tex]\mathrm{The \ slope \ of \ the \ graph \ of \ f(x)} =\dfrac{-2 - 2}{-1 - 0} = 4[/tex]
The equation of f(x) is; y - (-2) = 4·(x - (-1)), which gives;
y = 4·x + 4 - 2 = 4·x + 2
The y-intercept = 2
The slopes of the graphs of f(x) and g(x) are equal, therefore, f(x) ║ g(x)
The difference or the transformation that takes the y-intercept of f(x) to the
y-intercept of g(x) is; k = y-intercept(g(x)) - y-intercept(f(x)) = -3 - 2 = -5
Therefore, k = -5
Which gives;
g(x) = f(x) - 5
The value of k that transforms f into g is; k = -5

Given: ∠XAM = ∠YBM = 90° and AM = BM
To prove: BX ≅ AY
Proof:
In the triangle XAM and BYM:
∠3 = ∠4 [vertically opposite angles]AM = BM [Given]∠XAM = ∠YBM [Both are 90°]From the ASA rule of congruency, we can say that: ΔXAM ≅ ΔYBM
Since ΔXAM ≅ ΔYBM: We can say that XM ≅ MY [CPCT - Common Part of Congruent triangles]
In the Triangle AMY and XMB:
∠1 = ∠2 [vertically opposite angles]AM = BM [Given]XM = MY [Proved above]From the SAS rule of congruency, we can say that: ΔAMY ≅ ΔXMB
Since ΔAMY ≅ ΔXMB: We can finally say that BX ≅ AY [CPCT]
Hence Proved!

A boat can travel 20 miles on 10 gallons of gasoline. How much gasoline will it need to go 34 miles?
Answer:
20 divided by 10 is 2 so for every 2 miles it travels it uses 1 gallon of gasoline. 20 + 14 is 34 so you divide 14 by 2 to get 7. then you add 10+7 to get 17. it will take 17 gallons of gasoline to go 34 miles

1. Dear Math Helper,
I am in need of your help! I have a job where I design games. I am designing a game that involves a playing area
with 12 equal sections. Players randomly end up in one of the sections.
1 labeled one section, "Gain 40 points," four sections, "Gain 10 points," and the rest, "Try Again." Also, each
player automatically gives up 10 points with each move,
After trying out the game on some volunteers, I noticed that players tend to lose points in the long run. Without
changing the sizes of the sections, what adjustments can I make so that players are likely to earn at least one
Point in the long run?
Answer: Let them start off with a certain amount of money. So before they make a move they would have some points ahead of time.
Step-by-step explanation: Hope this helped!! :)
Well, you can actually increase the number of points for those sections and spread them across the sections so that as the players get in the long run, some points will be available for them.
What is video game?Video game refers to a device which is electronically controlled and played and involves the controlling of images displayed on the screen. Video games has really improved as technology keep advancing.
Thus, from the question above, if players will not lose points at the long run, then it's necessary points need to increase at the long run.

What is the sum of the exterior angles of a 54-gon?
Answer: The sum of the exterior angles of a 54-gon should be 360°.
Step-by-step explanation:
A polygon is a closed figure made up of straight lines like triangle (3-gon) , quadrilateral (4-gon) , square(4-gon), pentagon (5-gon) , octagon(8-gon) etc.
The sum of exterior angles of any polygon with n sides ( or n-gon ) is always 360 degrees.
A 54-gon is a polygon with 54 sides.
Therefore , the sum of the exterior angles of a 54-gon should be 360°.
