A sleep time of 15.9 hours per day for a newborn baby is at the 10h percentile of the distribution of sleep times for all newbor

Step2247 [10]

The mean time in hours per day for newborn babies is 16.5 hours ⇒ D

Step-by-step explanation:

A sleep time of 15.9 hours per day for a newborn baby is at the 10th

percentile of the distribution of sleep times for all newborn babies

Assuming the distribution is normal with a standard deviation of

0.5 hour

To find the mean time let us do that

1. Use the normal distribution table to find the corresponding z-score

for 10th percentile

2. Use the rule μ = x - zσ, where μ is the mean, σ is the standard

deviation and x is the score

3. Substitute the values of x, σ and z in the rule to find μ

Look to the normal distribution table to find z-score that equivalent

to the area = 10/100 = 0.1 (10th percentile)

∵ z-score = -1.28

∵ σ = 0.5 hour

∵ x = 15.9

∵ μ = x - zσ

- Substitute the values in the rule

∴ μ = 15.9 - (-1.28)(0.5)

∴ μ = 15.9 + 0.64

∴ μ = 16.54 ≅ 16.5 hours

The mean time in hours per day for newborn babies is 16.5 hours

You are searching online for techno music that is neither European nor Dutch. In set notation, which set of music files are you

yuradex [85]

<h2>Answer: </h2><h2>Techno ∩ (European ∩ Dutch)'</h2>

Step-by-step explanation:

According to sets theory ;

Intersection ( ∩ ) - e.g (European ∩ Dutch) represents both European and

Dutch , while (European ∩ Dutch)' represents neither

European nor Dutch .

Union ( ∪ ) - e.g (European ∪ Dutch) represents either European or Dutch .

So , Techno ∩ (European ∩ Dutch)' represents set notation of techno musics that is neither European nor Dutch .

Driving on the highway, you can safely drive 60 miles per hour. "How far can you drive in ‘h' hours?" What is the range of the f

JulijaS [17]

Answer:

D.The distance you drive

Step-by-step explanation:

If you describe this situation as function, then it will look as:

f(h)= 60h
For h=1 you have f(1)= 60 miles
For h=2 you have f(2)= 120 miles etc.

The range of the function is the set of output values

In this case the range is the distance you drive

Correct option is D.

Nathan has a collection of 220 baseball cards. He lets his brother 1/4 of his collection and sells 20% of his collection to the

tatyana61 [14]

<u>Answer:</u>

The baseball cards remain in Nathan’s collection is 106 cards

<u>Explanation:</u>

Total number of cards Nathan has= 220

Number of cards he let his brother have = 1/4 of his collection

= $\frac{1}{4} \times 220$ = 55 cards

Number of cards he sells = 20% of his collection

= $\frac{20}{100} \times 220$

=44 cards

No of cards he gives to his friends=15 cards

Remaining cards = total number of cards – (no of cards he gave to his brother+ cards he sold+ cards he gave to this friends)

= 220 – ( 55+44+15)

=220-114

=106 cards

baseball cards remain in Nathan’s collection is 106 cards
