Nope

Step-by-step explanation:

Linear equation : Y = Mx + C

gradient = M

Y-intercept  = C

To find gradient : (y1 - y2) / (x1 - x2):

(20 - (-25)) / (-4 - 11)

45 / -15 = -3

The given gradient is however 1/3. So The given equation is wrong

Answer:

m∡CBD = 135°

Step-by-step explanation:

m + 3m = 180

4m = 180

m = 180/4

m = 45

angle CBD is 3(45) = 135 degrees

Answer:

$7.99

Step-by-step explanation:

Arrange numbers in numerical order: $0, $1.99, $4.30, $6.45, $7.99, $7.99, $10.35, $16, $18.20, $18.95, $21.38.

Count how many numbers you have, 11.

11 is an odd number so, the number in the middle of the data set is the median.

Final answer: $7.99 is the median.

Answer:

x = 1

x = -9

Step-by-step explanation:

(2x2 +  16x) -  18  = 0

2x2 + 16x - 18  =   2 • (x2 + 8x - 9)

x2 + 8x - 9

 -9    +    1    =    -8

     -3    +    3    =    0

     -1    +    9    =    8

 2 • (x + 9) • (x - 1)  = 0

2   =  0

x+9 = 0  

x = -9

x-1 = 0

x = 1

x2 + 8x - 9  = 0

  x2+8x = 9

(x+4) • (x+4)  =

 (x+4)2

x2+8x+16 = 25 and

  x2+8x+16 = (x+4)2

(x+4)2 = 25

x = -4 + √ 25

 x2 + 8x - 9 = 0

has two solutions:

 x = -4 + √ 25

  or

 x = -4 - √ 25

           - B  ±  √ B2-4AC

 x =   ————————

                     2A

A   =     1

                     B   =    8

                     C   =   -9

B2  -  4AC   =

                    64 - (-36) =

                    100

 -8 ± √ 100

  x  =    —————

                   2

  x  =  ( -8 ± 10) / 2

x =(-8+√100)/2=-4+5= 1.000

or:

x =(-8-√100)/2=-4-5= -9.000

Answer:  x = 1

x = -9

Answer:

475/6%

Step-by-step explanation:

I hope this helps.

The equivalent fraction of the percentage is A = 47401/600

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given data ,

Let the fraction be represented as A

Now , the percentage value is given by P

And , the value of P = ( 79 1/6 ) %

We know that 1% is equivalent to 1/100, so we can write:

79 1/6% = 79 + 1/6% = 79 + 1/6 x 1% = 79 + 1/600

Now, we can convert the mixed number to an improper fraction by multiplying the whole number by the denominator and adding the numerator, then placing this over the denominator:

79 + 1/600 = (79 x 600)/600 + 1/600 = 47400/600 + 1/600

Combining these fractions, we get:

79 1/6% = 47401/600

Hence , 79 1/6% as a fraction is 47401/600.

Answer:

it's the first option or A

Step-by-step explanation:

well 9 * 10 is 90 which leaves you with the numbers 14 and 3 we used 10 so that gives us 4 and 3 multiply those and you get 12 so add 12 to 90 and you get 102 thus the answer is A

Answer:

80 cc.

Step-by-step explanation:

We work in amounts of salt in the solutions:

0.09x + 0.17*80= 0.13(x+ 80)  where x is the required volume of 9% solution.

0.09x + 13.6 = 0.13x + 10.4

13.6 - 10.4 = 0.13x - 0.09x

3.2 = 0.04x

x = 3.2 / 0.04

x = 80

Answer:

a) the 95% confidence interval for the true mean µ is 60.971, 65.629

The exact 95% confidence interval for the true mean µ is 60.971, 65.629

P (x`- ∝ s/√n<u <x`+ ∝ s/√n) = 0.95

Step-by-step explanation:

n= 50

x`= 63.3

s= 8.4 minutes

∝= 95%= ±1.96

The formula for calculating the confidence interval is:

x`± ∝ s/√n

Putting the values

x`± 1.96 s/√n

63.3 ± 1.96(8.4/√50)

63.3± 2.3287

60.971, 65.629

a) the 95% confidence interval for the true mean µ is 60.971, 65.629

b) Putting the values

x`± 1.96 s/√n

63.3 ± 1.96(8.4/√50)

63.3± 2.3287

The exact 95% confidence interval for the true mean µ is 60.971, 65.629

c) The prediction level tells that the drying time of the wall from 60.971 to 65.629 minutes must be in the range 95 % of the time.

And is given by

2 days with no professional sports game.

3 forms of ratio --> a to b, a : b, a / b

1) Remember there are 365 days in a year.

Days without games to Days in a year --> 2 to 365

Days without games : Days in a year --> 2 : 365

Days without games / Days in a year --> 2 / 365

2) Now there is a plot twist. It ask days with games. To find that we need to subtract 365 - 2 = 363 days with games.

Days with games to Days in a year --> 363 to 365

Days with games : Days in a year --> 363 : 365

Days with games / Days in a year --> 363 / 365

3) Days with games to Days without games --> 363 to 2

Days with games : Days without games --> 363 : 2

Days with games / Days without games --> 363 / 2

Hi there!

x-int: (6, 0)

y-int: (0, -9)

y = 3/2x - 9

Begin by finding the x-intercept. The x-intercept is located where y = 0, therefore:

0 = 3/2x - 9

Isolate for x by adding 9 to both sides:

9 = 3/2x

Divide both sides by 3/2x:

9 * 2/3 = x

x = 6. Thus, the x-intercept is at (6, 0).

Find the y-intercept by finding the y-value at which x = 0:

y = 3/2(0) - 9

y = -9. The y-intercept is at (0, -9).
