The table below shows that the number of miles driven by Taylor is directly proportional to the number of gallons she used.
Gallons Used /Miles Driven
42 1125.6
48 1286.4
50 1340
What is the constant of proportionality between the number of miles driven and the number of gallons used?
Answers
Answer:
24.3
Step-by-step explanation:
[tex]\frac{Gallons}{Miles} =\frac{Gallons}{Miles}[/tex]
[tex]\frac{g}{884.52} =\frac{22113}{910}[/tex]
910g = 25 x 884.52
[tex]\frac{910g}{910} =\frac{22113}{910}[/tex]
g = 24.3
This is the correct answer. Hoped this helped!
The constant of proportionality is 26.8
Calculating the number of miles driven per gallon of fuel used:
1125.6/42 = 26.8
1286.4/48 = 26.8
1340/50 = 26.8
we get 26.8 miles traveled in one gallon fuel.
if we represent gallons of fuel by x and miles traveled by y, the equation thus formed will be:
y = 26.8x
hence the constant of proportionality is 26.8

For a data set of the pulse rates for a sample of adult females, the lowest pulse rate is 37 beats per minute, the mean of the listed pulse rates is x=71.0 beats per minute, and their standard deviation is s=18.2 beats per minute. a. What is the difference between the pulse rate of 37 beats per minute and the mean pulse rate of the females? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the pulse rate of 37 beats per minutes to a z score. d. If we consider pulse rates that convert to z scores between −2 and 2 to be neither significantly low nor significantly high, is the pulse rate of 37 beats per minute significant?
Answers
Answer:
See below.
Step-by-step explanation:
(a) Difference = 71 - 37 = 34 beats/minute.
(b) Number of standard deviations = 34 /18.2 = 1.868.
(c) z score = (x - m )/ s where m = mean and s = standard deviation
= (37 - 71) / 18.2 = -1.868.
(d) This z score lies between -2 and 2 so a pulse rate of 37 is not significant.

Dr. Gordon has a scale drawing of a building site thr drawing uses the scale 2 in on the drawing for every 100 ft on the building site dr gordon marks a 6 in. by 3.2 in section of the draeing to show the section she will search what is the area of the section she will search?
Answers
The required area of the section Dr. Gordan will search is equal to 48,000ft².
As given in the question,
Scale used by Dr. Gordan
2 in = 100 ft
⇒1 in = 50 ft
Dr. Gordon marks a 6 in. by 3.2 in section
Length = 6 in
= ( 6 × 50 )ft
= 300ft
Width = 3.2in
= ( 3.2 × 50 )
= 160ft
Area of the section = length × width
= 300 × 160
= 48,000 ft²
Therefore, the required area of the section Dr. Gordan will search is equal to 48,000ft².

The three sides of a triangle are in different colors – blue, green and red. The ratio of the length of the blue side to the length of the green side to the length of the red side is 3 : 4 : 5. The perimeter of the triangle is 240 cm. a) Fill in the blank: ___ units = 240 cm b) Fill in the blank: 1 unit = ___ cm c) What is the length of the red side of the triangle?
Answers
Answer:
The perimeter is the distance around the triangle. Given the ratio, the perimeter using the ratio is;
= 3 + 4 + 5
= 12 units
a. 12 units = 240 cm
The perimeter in centimetres is 240cm and in ratio is 12 units so they are equivalent.
b. 1 unit = 20 cm
If 12 units are to 240 cm, 1 unit is;
= 240/12
= 20 cm
c. Length of red side;
Red side has length of 5 units. 1 unit is 20 cm.
Length in cm is;
= 5 * 20
= 100 cm

∠A and \angle B∠B are supplementary angles. If m\angle A=(7x+10)^{\circ}∠A=(7x+10) ∘ and m\angle B=(7x-26)^{\circ}∠B=(7x−26) ∘ , then find the measure of \angle A∠A.
Answers
Answer:
108 degrees
Step-by-step explanation:
Since angles A and B are supplementary, they both add up to 180. Angle A = 7x+10, and angle B = 7x-26. You can set up the equation A + B = 180, and then plug in angles A and B, which gives you 7x+10 + 7x-26 = 180. Then you just need to isolate x:
Combine like terms: 14x - 16 = 180
Add 16 to both sides: 14x = 196
Divide both sides by 14: x = 14
Now that you know x, you can plug it into the expression for angle A (7x+10):
A = 7(14) + 10 = 98+10 = 108
The mean of 20 observations is 12.5. By error, one observation was noted as (-15) instead of 15. Then the correct mean is ___?
Answers
Answer:
The correct mean is -12.5.
Step by step explanation:
If one of the 20 observations is a negative number, then the mean would be negative. This is because, when a negative number is in contact with (meaning added, subtracted, multiplied by) a positive number, the whole answer is negative, because it's opposite signs.

Use a two-column proof to prove the Triangle Proportionality Theorem:
*image attached*
Answers
Answer:
A line ED parallel to one side of the triangle {CB} has intersected the other two sides of the triangle [AB and AC] making the sides proportional.
Step-by-step explanation:
The Triangle Proportionality Theorem states that:
If a line parallel to one side of a triangle intersects the other two sides then it divides those sides proportionally. The segments joining midpoints of the two sides of the triangle will be parallel to the third side and half the length.
This means if a line divides two sides of a triangle proportionally, then it is parallel to the third side.
In this case;
AD/AB =AE/AC is true because;
A line ED parallel to one side of the triangle {CB} has intersected the other two sides of the triangle [AB and AC] making the sides proportional.
The segments{AD,AB,AE,EC] joining the midpoints {D & E} of the two sides {AB & AC} of the triangle will be parallel to the third side BC and half the length.
