What is the actual height of the building shown in the model?
julsineya [31]

Answer:

The actual height is 150ft

Step-by-step explanation:

Given

Width : Height = 2cm : 5cm

Actual\ width = 60ft

Required

Determine the actual height

Substitute 60ft for width in: Width : Height = 2cm : 5cm

60ft:Height =2cm:5cm

Express as fraction

\frac{60ft}{Height} =\frac{2cm}{5cm}

\frac{60ft}{Height} =\frac{2}{5}

Make height the subject

Height = \frac{5}{2} * 60ft

Height = 5 * 30ft

Height = 150ft

Vlada [557]

Answer:

The test statistic for this test is 3.82.

Step-by-step explanation:

The null hypothesis is:

H_{0} = 8500

The alternate hypotesis is:

H_{1} > 8500

Our test statistic is:

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the value tested at the null hypothesis, \sigma is the standard deviation of the population and n is the size of the sample.

In this question:

X = 8745, \mu = 8500, \sigma = 1200, n = 350

So

t = \frac{8745 - 8500}{\frac{1200}{\sqrt{350}}} = 3.82

The test statistic for this test is 3.82.

Use the table below. Do x and y have a proportional relationship? Explain.
nydimaria [60]

Answer:

No

Step-by-step explanation:

For x and y to have a proportional relationship, then

the ratio of k = \frac{y}{x} must be equal for all points

(2, 5) → k = \frac{5}{2} = 2.5

(3, 7.5) → k = \frac{7.5}{3} = 2.5

(5, 12.5) → k = \frac{12.5}{5} = 2.5

(18, 8) → k = \frac{18}{8} = 2.25 ≠ 2.5

k is not equal for all values , hence no proportional relationship exists
