Determine which integer(s) from the set S:{−40, 2, 20, 42} will make the inequality three eighths m minus three is less than one fourth m plus 2 false.

The dimensions of the rectangle will be equal to 10 by 4.

A rectangle may be defined as the closed figure having four sides with the interior angles equal to 90°. it has two dimensions the length and the width. The area of a rectangle may be defined as the product of its length and width. According to the question the area of the rectangle is given as 40 square units. Let us assume the length as 'l' units and width as 'b' units. It is given that length is 6 units greater than the width that is l = (b + 6).

Now, the area of the rectangle = l×b

40 = (b + 6)×b

40 = b² + 6b

=> b² + 6b - 40 = 0

=> b = [-6 ± √(36 + 160)]/2

=> b = (-6 ± 14)/2

=>b = 4 units, since width cannot be negative.

Now, length = b + 6 = 10 units.

Kelly gets 38.59 miles per gallon of gasoline

Miles drove by Kelly = 238 miles

Gasoline used by the car = 6 1/6 gallons

Gasoline used in the car in improper fraction = 37/6 gallons

Average fuel economy: Average fuel economy of a car gives the distance covered by the car in one gallon of gasoline. This is an important factor to consider while buying or using a car as it is a major source of expenditure for the car.

To calculate miles per gallon we use the following formula:

Miles per gallon = Miles driven/ Gasoline used in the car

= 238/(37/6)

= 238*6/37

Answer:

Step-by-step explanation:

Student A:

Mean 80.8

Median: 85.5

The Median is a higher score.

Student B:

Mean 82.7

Median: 79.5

Mean is a higher score

Answer:

Student A's median and Student B's mean would result in the highest grade.

Step-by-step explanation:

How to find the mean:

The mean is the average.

Therefore, you must add all numbers listed, then divide the added numbers by the amount of numbers you added together. Lastly, as instructed round to the nearest whole number.

- Student A : Mean = 81

Step 1 : 25+78+80+82+85+86+88+89+96+99 = 808

Step 2: 808 ÷ 10 = 80.8

Step 3: 80.8 ---> 81

- Student B: Mean = 83

Step 1: 71+77+77+79+79+80+88+89+91+96 = 827

Step 2: 827 ÷ 10 = 82.7

Step 3: 82.7 ---> 83

How to find the median:

The median is the middle number in a sorted list of numbers.

Therefore, you list all of the numbers from least to greatest. Then, you get rid of a number from each side until you finally get to the center number. If there are two numbers left in the center you then find the mean(average) of those numbers.

- Student A: Median = 86

Step 1: Knock off a number from each side until you reach the center number(s)

25, 78, 80, 82, 85, 86, 88, 89, 96, 99 ---> 85, 86

Step 2: Find the mean(average) of the two central numbers

85 + 86 = 171 ---> 171 ÷ 2 = 85.5

Step 3: Round your answer

85.5 ---> 86

- Student B: Median = 80

Step1: Knock off a number from each side until you reach the center number(s)

71, 77, 77, 79, 79, 80, 88, 89, 91, 96 ---> 79, 80

Step 2: Find the mean(average) of the two central numbers

79 + 80 ---> 159 ÷ 2 = 79.5

Step 3: Round your answer

79.5 ---> 80

The answer is

x = 7, -7, √2, -√2

Add the two equations to get

x2 + y2 = 74

Eliminate y from the first by solving for y and using that result:

(x2 − 14) = x√74 - x2

square both sides, then condense:

x4 − 51x2 + 98 = 0

These ready factors:

(x−7)(x+7)(x−√2)(x+√2)=0

I'll let you handle it from there, but keep in mind that if we square all sides, we might find roots that need to be pulled out afterward.

Therefore,

x = 7, -7, √2, -√2

The probability that the shorts of the basketball team will be of a different color than the jersey is 2/3.

Probability can be found using the following formula;

probability = number of favorable outcomes or events ÷ total number of outcomes or events

In order to calculate the probability that the shorts will be of a different color than the jersey, we first determine the total number of combinations that are possible;

1- Black-Black

2- Black-White

3- Black-Gold

4- Gold-Black

5- Gold-White

6- Gold-Gold

Hence there are a total of 6 possible combinations of shorts and jerseys out of which 2 are the same and 4 are different.

Therefore the probability that the shorts will be of a different color can be calculated as follows;

probability = number of favorable outcomes or events ÷ total number of outcomes or events

probability = 4 ÷ 6

probability = 2/3

Hence, 2/3 is the probability that the shorts will be of a different color than the jersey.

substitute 4,2 in the equation y=mx+b and solve for b.

2 = 2x4+b

b=-6

y = 2x - 6

Answer:

Slope intercept formula: y = 2x -6

Point Slope formula y = 2x-6

Step-by-step explanation:

1) Find the slope

2) Choose a point and plug it into the equation y = mx+b

3) Solve for b

4) Plug-in new slope (m) and new y-intercept (b) into equation y = mx+b

Solving:

4 = x1

2 = y1

7 = x2

8 = y2

to find slope with slope formula:

m = y2-y1/x2-x1 = 8-2/7-4 = 6/3 = 2

now plug in,

y = 2x+b

to find b, take any one of the pair

(i will choose (4,2) )

2 = 2(4) + b

now solve for b,

2 = 8+b

b = -6

Slope intercept formula: y = 2x -6

for point slope: y-y1 = m(x-x1)

as we know our slope is 2 and points are (0,-6) where 0 is x1 and -6 is y1

now we plug in,

y-(-6) = 2(x-0)

y+6 = 2x

Point Slope formula y = 2x-6

The speed for maximum car mileage will be 48 mph. The maximum gas mileage will be 29.5 mpg.

We are provided with an equation for mileage of car as

m(x) =  -0.028x² + 2.688x  -35.012

here , variable 'x' is the speed of the car.

Now

for the maximum speed of the car we have to first take the derivative of m(x) and then for the boundary value condition by  putting the derivative equal to zero.

comparing to the equation  ax² + bx + c , if the value of

'a' is positive, then we have minimum value at 1st derivative = 0

'a' is negative we have maximum value .

in this case a = -0.028 ( -ve) so we will have a maxima at 1st derivative.

so, dm/dx = -0.056x + 2.688

putting the 1st derivative = 0 , we have

x = 48

therefore , car gets maximum gas mileage at speed of 48 mph.

Also , putting this value in equation (1) we will get max. mileage.

so max. mileage = -0.028 (48)² + 2.688 x 48 - 35.012

                           = -64.512 + 129.024 - 35.012

                           = 29.5

so the maximum gas mileage will be 29.5 mpg .

axis of symmetry: x = -7

Step-by-step explanation:

f(x) = 1/7 * (x^2 + 14x + 35)

f(x) = 1/7 * (x^2 + 14x) + 5

f(x) = 1/7 * (x^2 + 14x + 7^2 - 7^2) + 5

f(x) = 1/7 * (x^2 + 14x + 7^2 - 49) + 5

f(x) = 1/7 * (x^2 + 14x + 7^2) + 5 - 7

f(x) = 1/7 * (x + 7)^2 + 5 - 7

f(x) = 1/7 * (x + 7)^2 - 2
