you have to do y2-y1 over x2-x1
then you plot in your points :
y2=-2
y1=-4
x1=-1
x2=-6
after you do that you need to subtract them and that's how you will get your answer.

In a group of students, 50% of the students were taking statistics subject, 30% economics and 10% both the subjects. What is the probability that a student was taking neither statistics nor
economics?
a) 30% b) 90%
c) 70% d) None of these
Solution with som explanation
Answer:
a) 30%
Step-by-step explanation:
50% of the students were taking statistics subject, 30% economics and 10% both the subjects.
The probability a student takes only statistics = 50% - 10% = 40%
The probability a student takes only economics = 30% - 10% = 20%
The probability a student was taking neither statistics nor economics = 100% - (40% + 20% + 10%)
The probability a student was taking neither statistics nor economics = 30%
A family is calculating the cost for one semester of college next year. Each hour of class will cost $155. A scholarship gift of $64 can be deducted from costs. If h is the number of hours taken, and c is the total cost, which equation can be used to calculate the total tuition costs for a semester?
C=89h
C=155h+64
C=155h-64
C=-155h-64
Answer:
c=155h-64
Step-by-step explanation:
you mulitply the cost of the classes by the amount of hours, then you deduct the scholarship gift(64) from the total and get your total cost of the semester

Find the diagonal of the box using the Pythagorean Theorem.
Answer:
26 cm
Step-by-step explanation:
Given:
Length = 24 cm
Width = 8 cm
Height = 6 cm
Required:
Diagonal of the box
SOLUTION:
Using the pythagorean theorem, [tex] a^2 + b^2 + c^2 = d^2 [/tex], where,
a, b and c are the dimensions of the box, and d is the length of the diagonal.
Plug in the value into the formula
[tex] 24^2 + 8^2 + 6^2 = d^2 [/tex]
[tex] 676 = d^2 [/tex]
[tex] \sqrt{676} = \sqrt{d^2} [/tex]
[tex] 26 = d [/tex]
Length of diagonal of the box = 26 cm

Mikah and Gracie were running laps at the local gym. Mikah ran 1 and 4/8 laps, and Gracie ran 1 and 1/2 laps. Who ran a further distance?
Answer:
Trick question they both ran equal distance
Step-by-step explanation:
Gracies distand 1 and 1/2 is already in simplist form, but Mikahs distance 1 and 4/8 can be reduced.
More specifically the fration 4/8 can be reduced, finding the largest common multiple between 4 and 8 we find that 4 is the largest number that goes into both.
This results in the simplification of 1 and 4/8 to 1 and 1/2 which is the same as Gracies distance.

Lucinda is saving money for a hot-air balloon trip to celebrate her graduation. She needs $300 dollars. Express this amount as an integer. Is this represented by a negative number or a positive number?
Answer:
Positive number
Step-by-step explanation:
Given that:
Lucinda is saving money for a hot-air balloon trip to celebrate her graduation and she needs $300 dollars.
Let x be the amount of her savings and she needs $300
SO;
x + 300 = 0
As an integer, it is represented by a positive number because she needs this amount of money in addition to what she already saved.
Jackson´s Bakery sold 102 ice cream cakes and 68 fruit tarts in one weekend. Ice cream cakes are $27 and fruit tarts are $15. How much did Jackson's Bakery make in one weekend
Answer:

102 ice cream cakes, and 68 fruits tarts
One cream cake is $27 and a fruit tart is $15
Meaning, from ice cream cakes, they made 102($27) = $2754
From fruits tarts, they made 68($15) = $1020
A kite of area 40 m squarehas one diagonal 2 m longer than the other. Find the length of the diagonal
Answer:
Length of diagonal 1: 8 metersLength of diagonal 2: 10 metersStep-by-step explanation:
Let d1 be the first diagonal and d2 be the second diagonal.
Given
Area = 40 square meters
And one diagonal is 2 meter longer than other
[tex]d_2 = d_1+2[/tex]
The formula for area of kite is;
[tex]Area = \frac{1}{2} * d_1 * d_2[/tex]
Putting the known values
[tex]40 = \frac{1}{2} * d_1 * (d_1+2)\\80 = (d_1)^2+2d_1\\d_1^2 +2d_1-80 = 0\\[/tex]
The expression is a quadratic polynomial
Factorizing
[tex]d_1^2 + 10d_1-8d_1-80 = 0\\d_1(d_1+10)-8(d_1+10) = 0\\(d_1+10)(d_1-8) = 0\\d_1 + 10 = 0\\d_1 = -10\\d_1-8 = 0\\d_1 = 8[/tex]
As the value of length cannot be negative so discarding the negative value
[tex]d_1 = 8d_2 = d_1+2 = 8+2 =10[/tex]
Hence,
Length of diagonal 1: 8 metersLength of diagonal 2: 10 metersThe drama club at NAMS sells hot chocolate and coffee at the high school football games. At the last game, they had sales of $200. They need to keep track of how many of each type drink was sold so that they can make predictions for future sales. Monica knows that they used 275 cups that night. If the hot chocolate sells for 75 cents and coffee sells for 50 cents, how much of each type of drink were sold?
Answer:
Coffee = 25
Hot Chocolate = 250
Step-by-step explanation:
Coffee: c
Hot Chocolate: h
0.75h + 0.50c = 200
h + c = 275
h + c = 275
h = 275 - c
0.75h + 0.50c = 200
0.75(275 - c) + 0.5c = 200
206.25 - 0.75c + 0.5c = 200
-0.25c = -6.25
-0.25c/-0.25 = -6.25/-0.25
c = 25
0.75h + 0.5(25) = 200
0.75h + 12.5 = 200
0.75h = 200 - 12.5
0.75h = 187.5
0.75h/0.75 = 187.5
h = 250
Check: c = 25; h = 250
0.75h + 0.50c = 200
h + c = 275
0.75(250) + 0.5(25) = 200
187.5 + 12.5 = 200
200 = 200
h + c = 275
250 + 25 = 275
275 = 275
The drama club sold 250 hot chocolates and 25 coffee drinks.
EquationEquation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the number of hot chocolate and y represent the number of coffee. From the question the equation are:
x + y = 275 (1)0.75x + 0.5y = 200 (2)From both equations:
x = 250, y = 25

Your overall formula for finding the volume of these multi-faceted shapes is V = (l x w x h) / 3. Basically, your first step is finding the area of the base by multiplying length by width. Once you determine the area of the base, multiply that by the height.

Step-by-step explanation:
A rabbit moves n times as fast as a squirrel . A fox moves m times as fast as a rabbit . The fox moves how many times as fast as the squirrel?
Answer:
the fox moves mn times as fast as the squirrel
Step-by-step explanation:
the easiest way to do problems like this is by using hypothetical values that make sense (it's best to avoid 0, 1, and 2)
we'll say that n = 3 and m = 4
so if the squirrel moves at s pace, then the rabbit moves at ns, or 3s.
if the fox moves at m (4) times the rabbit's pace (3s), then it moves at 4(3s)
then just switch out the numbers for their variables, giving you m(ns)
remember that s simply represents the squirrel's pace, we cannot replace it with a number in this case, so switch it with the idea/value it represents
and there you go, mn times the squirrel's pace
