Answer:

V =165 ft^3

Step-by-step explanation:

V = Bh  Where B is the area of the base and h is the height

B is the area of the triangular base

B = 1/2 (5) *6

B = 15 ft^2

V = 15 * 11

V =165 ft^3

NO LINKS!! Explain your answer (show the support by showing the changes in x and y on your table). If the relationship is linear
ivolga24 [154]

Answer:

  • relationship: inverse
  • equation: y = 25/x

Step-by-step explanation:

You are correct that the relationship is inverse, and that the product of x and y is a constant, 25.

__

The equation should be written so that y is a function of x:

  \boxed{y=\dfrac{25}{x}}

The x in the denominator clearly shows that y is proportional to the inverse of x.

this is a blueprint drawing of the stage area at Millennium Park the length of one square on the grid is equal to 5 feet accordi
dmitriy555 [2]

Answer:

No, diagonal of square C is 70.71ft

Step-by-step explanation:

Given in the question that length of one square = 5 ft

Length of Square C = 10 small squares

1 square = 5 ft

10 square = 5ft * 10

                = 50 ft

As we know that in a square all side are of equal length and make an angle of 90° at each corner.

So, by using pythagorus theorem

Diagonal of square² = side² + side²

Diagonal of square² = 2side²

Diagonal of square = √(2side²)

Diagonal of square = √2 (side)

where side = 50 ft

Diagonal of square = √2 (50)

Diagonal of square = 70.71 ft

We wish to give a 90% confidence interval for the mean value of a normally distributed random variable. We obtain a simple rando
coldgirl [10]

Answer: (9.27025,\ 11.12975)

Step-by-step explanation:

Given : Sample size : n= 9

Degree of freedom = df =n-1 =8

Sample mean : \overline{x}=10.2

sample standard deviation : s= 1.5

Significance level ; \alpha= 1-0.90=0.10

Since population standard deviation is not given , so we use t- test.

Using t-distribution table , we have

Critical value = t_{\alpha/2, df}=t_{0.05 , 8}=1.8595

Confidence interval for the population mean :

\overline{x}\pm t_{\alpha/2, df}\dfrac{s}{\sqrt{n}}

90% confidence interval for the mean value will be :

10.2\pm (1.8595)\dfrac{1.5}{\sqrt{9}}

10.2\pm (1.8595)\dfrac{1.5}{3}

10.2\pm (1.8595)(0.5)

10.2\pm (0.92975)

(10.2-0.92975,\ 10.2+0.92975)

(9.27025,\ 11.12975)

Hence, the 90% confidence interval for the mean value= (9.27025,\ 11.12975)
