a property owner wants to build a small bridge across a stream running through his field. He knows that the weight the bridge ca

n support is inversely proportional to the length of the bridge. If he builds the bridge across the widest part of the stream, which is 4 feet in length, the bridge can hold 120 pounds of weight. How much weight can the bridge support if he builds it across the part of the stream that is 2.5 feet in length

MrRissso [65]

Answer:

Option A) 0.0074    

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 110

Sample mean, \bar{x} = 20

Sample size, n = 100

Alpha, α = 0.05

Population standard deviation, σ = 115.35

First, we design the null and the alternate hypothesis

H_{0}: \mu = 110\\H_A: \mu \neq 110

We use two-tailed z test to perform this hypothesis.

Formula:

z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }

Putting all the values, we have

z_{stat} = \displaystyle\frac{115.35 - 110}{\frac{20}{\sqrt{100}} } = 2.675

Now, we calculate the p-value from the standard normal table.

P-value  = 0.0074

Thus, the correct answer is

Option A) 0.0074

a beetle is 1.8cm long. a drawing of the beetle is made using a scale of 5:1. what is the length of the beetle in the drawing?
Delvig [45]

Answer: The length of the beetle in the drawing is 9 cm.

Step-by-step explanation:

Hi, since is a scaling up scale, we have to multiply the original length of the beetle (1.8 cm) by 5 to obtain the length of the beetle in the drawing.

Mathematically speaking

5 x 1.8 = 9 cm

The length of the beetle in the drawing is 9 cm.

This type of scale is used to increase in size.

Feel free to ask for more if needed or if you did not understand something.
