Answer:

NO SOLUTION.

Step-by-step explanation:

As both the expressions in x are equal to y we can write:

-2x + 2 = -2x - 2 Adding 2x and - 2 to both sides:

-2x + 2 + 2x - 2 = -2x + 2x - 2 -2

-2x + 2x = -2 - 2

0 = -4

- which is absurd so there is NO SOLUTION to this system of equations.

Answer:

Step-by-step explanation:

Y=-2x+2.....(1)

Y=-2x-2.....(2)

Subtracting (1) from (2)

Y - Y = -2x - (-2x) -2 - 2

O = -2x + 2x - 4

O = 0 - 4

Hence it as no solution the the two variables tend to zero

Answer:

The 95% confidence interval for the true mean resale value of a 5-year-old car of this model

(11,688.68 , 12,511.32)

Step-by-step explanation:

Step(i):-

Given sample size 'n' = 17

mean of the sample x⁻ = 12,100

Standard deviation of the sample (S) = 800

The 95% confidence interval for the true mean resale value of a 5-year-old car of this model

$(x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} + t_{0.05} \frac{S}{\sqrt{n} } )$

Step(ii):-

Degrees of freedom ν =n-1 = 17-1 =16

$t_{(16 , 0.05)} = 2.1199$

The 95% confidence interval for the true mean resale value of a 5-year-old car of this model

$(x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} + t_{0.05} \frac{S}{\sqrt{n} } )$

$(12,100 - 2.1199\frac{800}{\sqrt{17} } , 12,100 + 2.1199 \frac{800}{\sqrt{17} } )$

(12,100 - 411.32 , 12,100 + 411.32)

(11,688.68 , 12,511.32)

The figure below is a regular pentagon. If mZBAE = 5x + 3, find the value of x.

Pepsi [2]

Answer:

x = 21

Step-by-step explanation:

For a pentagon, n = 5.

Each angle measures:

(n - 2)180/5 = (5 - 2)(180)/5 = 108

5x + 3 = 108

5x = 105

x = 21

The statue of liberty is 305.5 feet tall from the foundation of it pedestal to the top of its torch Isla is building a model of

Effectus [21]

Answer: The actual model is 3.055 feet tall.

Step-by-step explanation:

Given: The statue of liberty is 305.5 feet tall from the foundation of it pedestal to the top of its torch .

The height of the model of the statue = $\dfrac{1}{100}\times\text{ (Height of actual model)}$

$=\dfrac{1}{100}\times305.5\\\\=3.055\text{ feet}$

Hence, the actual model is 3.055 feet tall.
