Let's solve this using unitary method ~

$\sf3 \: seconds = 63 \: meters$

$\sf1\: second= 63 \div 3 \: meters$

$\sf1\: second= 21 \: meters$

$\sf5\: seconds= 21 \times 5 \: meters$

$\sf5\: seconds= 105 \: meters$

Therefore , the ostrich will run 105 meters in 5 seconds.

The following situation calls for a significance test. State the appropriate null hypothesis <img src="https://tex.z-dn.net/?f=H

harina [27]

Answer:

$H_{0}: \sigma = 10\\$

$H_{a}: \sigma > 10\\$

Step-by-step explanation:

We are given the following in the question:

The organizers estimate that the variation in distance flown by the athletes will be σ = 10 meters.

This will be stated by the null hypothesis.

$H_{0}: \sigma = 10\\$

It was claimed that the organizers are underestimating the variation and the variation in distance is greater than 10.

This will be stated by the alternate hypothesis.

$H_{a}: \sigma > 10\\$

The parameter for the given hypothesis is standard deviation, $\sigma$ .

Starting at home, Luis traveled uphill to the gift store for 50 minutes at just 6 mph. He then traveled back home along the same

Orlov [11]

Let S = his average speed.

Let D = distance traveled one way

Time = distance / speed

Set up an equation:

d/6 + d/12 = 2d/S

Multiply the equation by 12s:

12s(d/6) + 12s(d/12) = 12s(2d/s)

Simplify to get:

2sd + sd = 24d

Combine like terms:

3sd = 24d

Divide both sides by d:

3s = 24

Divide both sides by 3:

s = 24/3

s = 8

His average speed was 8 mph.
