What is the slope of the line graphed below?

A) -5/2
B) 5/2
C) -2/5
D) 2/5

Answer:127.45

Step-by-step explanation:

Percentage solution with steps:

Step 1: We make the assumption that 51 is 100% since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that $100\%=51$.

Step 4: In the same vein, $x\%=65$.

Step 5: This gives us a pair of simple equations:

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

Step 7: Taking the inverse (or reciprocal) of both sides yields

Therfore: 51% of 65 is 127.45

Answer: The mean is equal to the median.

Step-by-step explanation:

Median is the middle value of a given data set. In asymmetric distribution, the data on the left side of the median is equal to the data on the right side of the median. Therefore, the mean of that data is equal to the median of the symmetric distribution.

Answer:

ANGLE CBE=25°

EXPLANATION:

LET ANGLE CBE BE X.

ANGLE CBE = ANGLE ABD

CBE=ABD=X

X+X+155°+155°=360°

2X+310°=360°

X=360-310/2

X=50/2

X=25°

Answer:

A ≈ 2 ft²

Step-by-step explanation:

The area (A) of a triangle using Heron's formula is

A = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]

where s is the semiperimeter and a, b , c the sides of the triangle.

s = [tex]\frac{a+b+c}{2}[/tex] = [tex]\frac{4+4+1}{2}[/tex] = [tex]\frac{9}{2}[/tex] = 4.5

Then

A = [tex]\sqrt{4.5(4.5-4)(4.5-4)(4.5-1)}[/tex]

   = [tex]\sqrt{4.5(0.5)(0.5)(3.5)}[/tex]

   = [tex]\sqrt{3.9375}[/tex]

   ≈ 1.9843...

   = 2 ft² ( to the nearest square foot )

Answer:

its either 1/6 or 3/8

Step-by-step explanation:

3/8 if you are dividing

1/6 if you are multiplying

Answer:

y = x - 6

Step-by-step explanation:

the slope-intercept form for any line is y = mx + b, where m is the slope and b is the y-intercept.

now, let's calculate the slope:

1-2/7-8= -1/-1 = 1

here is the equation we currently have solved: y = x + b

now we have to solve for the y-intercept. to do this, we substitute one of the given points into the equation, and solve for b.

let's use (8, 2). in this ordered pair, the 8 is the x, and the 2 is the y.

2= 8 +b

2 -8=b

b=-6

and now we have our final equation!

y = x - 6

Ok done. Thank to me :>

The given equivalent function is g(x)=(x+9)(x-2). Therefore, option B is the correct answer.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The given function is g(x)=x²+7x-18

Now, g(x)=x²+9x-2x-18

g(x)=x(x+9)-2(x+9)

g(x)=(x+9)(x-2)

Therefore, option B is the correct answer.

Answer:

90 cm^2

Step-by-step explanation:

Divide the rectangle and square into two separate figures and add them together at the end.

Top rectangle: We know that area of a rectangle is A=lw. Here, we see that w=5 cm. For the length, we add 4+5+4=13 (5 comes from the bottom square). So A=5(13)=65

Bottom square: Area of a square is A=s^2 where s=5 in this case, so A=5^2=25

Total Area: Add together two figure's area: A=65+25=90 cm^2

Answer:

Add all cups of sugar, which would be 20 divided it by 5( the number of students in the class) 20/5=4

Answer:

4

Step-by-step explanation:

Number of students - 5 (count the number of cup of sugar

Total number of sugar cups - 3+4+5+3+5 - 20

Number of cups of sugar each student got - 5/20

= 4

Step-by-step explanation:

(a)

ii.

21 - 5 = 16 play only chess.

iii.

23 - 5 = 18 play only cards

5 play both.

that is 16+18+5 = 39 that play at least one of these games.

i.

so, 45 - 39 = 6 don't play any of these games.

(b)

we have 16+18 = 34 pupils out of 45 that play exactly one game.

so the probabilty to pick one of them is as usual

desired cases / total cases = 34/45 =
