Answer:

x =  \frac{17}{13}  = 1 \frac{4}{13}

Step-by-step explanation:

-5(2x - 5) = 8 + (5 - 2x)

-10x + 25 = 8 + 3x

-10x - 3x = 8 - 25

-13x = -17

A garden is made up of two squares and a quarter circle. What is the area of the garden?
Elanso [62]

9514 1404 393

Answer:

  100.27 ft^2

Step-by-step explanation:

The area of each square is ...

  A = s^2 = (6 ft)^2 = 36 ft^2

The area of the 1/4 circle is ...

  A = 1/4πr^2 = 1/4π(6 ft)^2 = 9π ft^2 ≈ 28.27 ft^2

__

The area of the garden is the sum of the areas of the quarter circle and the two squares:

  A = 28.27 ft^2 + 2×36 ft^2 = 100.27 ft^2

The area of the garden is about 100.27 square feet.

Find the z-scores (two of them) that separate the middle 48% of the distribution from the area in the tails of the standard norm
djverab [1.8K]

Answer:

The  z-scores are   Z_{\frac{\alpha }{2} } =  0643 and  Z_{\frac{\alpha }{2} } =  - 0643

Step-by-step explanation:

From the question we are told that

    The  middle of the distribution area considered is  48%

Now the rest of the area under the standard normal distribution area is  mathematically evaluated

      \alpha  =  100-  48

      \alpha  = 52 \%

      \alpha  =  0.52

Now to obtain the area occupied by this proportion at the two tails we divide by 2 i.e

    \frac{\alpha }{2} =  \frac{0.52}{2}  =0.26

Now the z-score is obtained from the normal distribution table and the value is

     Z_{\frac{\alpha }{2} } \pm 0.643

The \pm shows that we are considering the two-talil
