astra-53 [7]2 years ago
4 0

Answer:

10

Step-by-step explanation:

d = √(x2  -x1)² + (y2 - y1)²

√(-6 - 0)² + [1 - (-7)]²

√(-6)² + (8)²

√(36) + (64)

√100

= 10

What is the area of rectangle ABCD with vertices A -3,0 B 3,2 C 4,-1 D -2,-3
Naddik [55]

For this, simply find the width and length by finding the distance between the two points. This can be done using the equation \sqrt{(y2 - y1)^2 + (x2 - x1)^2}

AB(length): \sqrt{(0 - 2)^2 + (3 - (-3))^2}

--> \sqrt{-2^2 + 6^2}

---> \sqrt{40} = 6.32

BC(width): \sqrt{(2 - (-1))^2 + (4 - 3)^2

--> \sqrt{(2 + 1)^2 + 1^2}

---> \sqrt{27 + 1}

----> \sqrt{28} = 5.29 ≈ 5.3

Area = 33.496 ≈ 33.5

The director of a state agency believes that the average starting salary for clerical employees in the state is less than $30,00
ss7ja [257]

Answer:

The test statistics is   z = -1  

Step-by-step explanation:

From the question we are told that

   The sample size is  n  =  100

  The null hypothesis  is  H_o : \mu = \$30000

   The alternative hypothesis is  H_a  :  \mu  < \$ 30000

   The sample mean is  \= x  = \$29,750

    The standard deviation is  \sigma  = \$2,500

    The level of significance is  \alpha =0.05

Generally the test statistics is mathematically represented as

        z = \frac{\= x - \mu }{ \frac{ \sigma}{ \sqrt{n} } }

=>      z = \frac{29750 - 30000 }{ \frac{ 2500}{ \sqrt{100} } }

=>      z = -1
