Answer:

3.25

Step-by-step explanation:

Answer:

m=0.7404, b=3.9117m=0.7404,b=3.9117

y=0.7404x+3.9117y=0.7404x+3.9117

x=18x=18

y=0.7404(18)+3.9117=17.2389y=0.7404(18)+3.9117=17.2389

Residual

16-17.2389= -1.238916−17.2389=−1.2389

-

The residual value for x = 18 is,

⇒ 16 - 17.24

⇒ - 1.24

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Now, We know that;

Equation is,

y = bx + a

Where,

b = (xy) - (x) (y) / x² - y²

Here, We have;

x = 12.5

y = 13.17

(xy) = 211.17

Hence, We get;

b = (211.17 - 164.625) / (219.17 - 156.25)

b = 0.74

So, We get;

y = bx + a

13.17 = 0.74 × 12.5 + a

a = 3.92

So,

y = 0.74x + 3.92

y = 0.74 × 18 + 3.92

y = 17.24

Thus, the residual value for x = 18 is,

⇒ 16 - 17.24

⇒ - 1.24

Answer:

0.5

Step-by-step explanation:

5+a•b, 2•3 is 6, +5 is 11.

4+6•b, 6•3 is 18, +4 is 22.

I'm using PEMDAS/GEMDAS, which means I did multiplication first.

I'm assuming the / means to divide, so 11/22 is 0.5

The equation represents decay by a rate of 2%

The starting amount is 1000 in this equation

The time value in this equation is 4

8.

Step-by-step explanation:
The ratio or fraction for this problem would be 1 (gold coin) : 25 (points)

If we want to find out how many gold coins he needs to get 200 points we need to divide 200 by 25.

200/25 : 8

if we want to check our answer do this
1:25
1 x 8 is 8
25 x 8 is 200

If  the circle below with secants BCD and FED then length of BC is 7.3cm

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

Let BC = x cm

BD=x+6

FD=11+5

From power of a point to circle

BD.CD=DF.ED

(x+6)6=16×5

6x+36=80

Subtract 36 from both sides

6x=80-36

6x=44

Divide both sides by 6

x=7.3

Hence, if  the circle below with secants BCD and FED then length of BC is 7.3cm

The equation of the line perpendicular to x-8y = 16 and passes through the point (2,-2) is y = -8x + 14.

A linear equation is in the form:

y = mx + b

where m is the rate of change (slope) and b is the y intercept.

Given the line is x - 8y = 16:

8y = x - 16

y = x/8 - 2

The slope of the line is 1/8, the slope of the line perpendicular is -8. Hence, since it passes through (2 -2):

y - (-2) = -8(x - 2)

y = -8x + 14

The equation of the line perpendicular to x-8y = 16 and passes through the point (2,-2) is y = -8x + 14.

Answer:

Step-by-step explanation:

The experimental probability of getting a green ball on the next trial of the Leon is 6/25.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

Experimental probability of an event is the ratio of number of time a particular event occur to the total number of trials.

Leon has a bag of 4 red balls, 3 green balls and 6 yellow balls. He takes a ball out and replaces it 50 times.  Out of those 50 trials he pulls out a green ball 12 times.

Here, the number of green ball pulls out is 12 times and the total number of times trials is 50. Thus the experimental probability of getting a green ball is,

[tex]P=\dfrac{12}{50}\\P=\dfrac{6}{25}[/tex]

Thus, the experimental probability of getting a green ball on the next trial of the Leon is 6/25.
