Mario is walking away from a motion detector at a rate of 1.5 feet per second. He started recording his distance from the motion
kipiarov [429]

Answer:

6 seconds

Step-by-step explanation:

Initial distance of Mario from motion detector = 2 ft

Speed of Mario = 1.5 ft/sec

Total distance of Mario from motion detector = 11 ft

Total distance moved by Mario while walking at the rate of 1.5 ft/sec = 11 - 2 = 9 ft

Given that:

Distance = 9 ft

Speed = 1.5 ft/sec

<em>Formula:</em>

Distance = Speed \times Time

\Rightarrow 9 =1.5 \times Time\\\Rightarrow Time = \dfrac{9}{1.5}\\\Rightarrow Time = \bold{6\ sec}

So, at <em>6 seconds</em>, Mario will be 11 ft from the motion detector.

When analyzing the list of nouns to determine whether to exclude a particular noun as an important "thing," which of the followi
anyanavicka [17]
<h2>Answer:</h2>

<em><u>(a) Is it an output from the system? </u></em>

<em><u>(d) Is it a synonym of an existing thing?</u></em>

<h2>Step-by-step explanation:</h2>

In the question,

We have a list of nouns and we need to determine whether a particular noun should be excluded by identifying particular noun as an important 'thing'.

So, to identify it as a noun we can ask two questions which will distinguish between the same.

<u>(a) Is it an output from the system? </u>

It is one of the questions that can be asked because if the thing is an output from a system it will be definitely existing in real therefore, we can identify from this.

<u>(d) Is it a synonym of an existing thing?</u>

By asking this we can also confirm whether a particular thing is a noun or not because if the thing will be a synonym for an already existing material, it definitely will be a Noun.

<em><u>Therefore, the correct option is (a) and (d).</u></em>

A woman is randomly selected from the 18-24 age group. For women of this group, systolic blood pressures (in mm Hg) are normally
dybincka [34]

Answer:

0.0274

Step-by-step explanation:

The mean is \mu =114.8 and the standard deviation is \sigma =13.1.

Calculate

Z=\dfrac{X-\mu}{\sigma}

for X=140:

Z=\dfrac{140-114.8}{13.1}\approx 1.9237.

If X\sim N(114.8,\ 13.1), then Z\sim N(0,1)

and

Pr(X>140)=Pr(Z>1.9237).

Use table for normal distribution probabilities to get that

Pr(Z>1.9237)=1-Pr(Z\le 1.9237)=1-0.9726=0.0274.

What is 0.3636363636 to the nearest thousandth?
Bad White [126]

Answer: 0.364

The reason that it would be 0.364 is because the thousandths place is the third decimal place, which would leave you with a 3 but since there is a 6 after the 3, the 3 would be rounded up to a 4.
