The average adult gets 7.45 hours of sleep each night, with a standard deviation of 0.65 hours. A pharmaceutical company develop
eduard

Answer:

At least 8.96 hours of sleep to be in the top 1%.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

\mu = 7.45, \sigma = 0.65

How many hours of sleep to be on the top 1%?

The top 1% is the 100 - 1 = 99th percentile, which is X when Z has a pvalue of 0.99. So X when Z = 2.327. Then

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

2.327 = \frac{X - 7.45}{0.65}

X - 7.45 = 0.65*2.327

X = 8.96

At least 8.96 hours of sleep to be in the top 1%.

Triangle WXY has coordinates W(1, 4), X(1, 1), and Y(4, 1). Which of the following sets of points represents a dilation of trian
Dmitrij [34]
The answer is the second option, option B, which is: B. <span>W'(2,8), X'(2,2), Y'(8,2)
</span> The explanation is shown below:
 You have the Triangle WXY has coordinates W(1,4), X(1,1), and Y(4,1) and the Triangle of the option B has coordinates W'(2,8), X'(2,2), Y'(8,2). As you can notice, the coordinates of the new triangle are the result of multiply the coordinates of the original triangle by a scale of factor of 2. Therefore, in other words, the Triangle WXY was dilated with a scale of factor of 2.

Can someone who is eligible help me with this.?
Murrr4er [49]

Answer:

Step-by-step explanation:

volume of one cube = ½×½×½ = ⅛ cm³

volume of prism = 5×3×6 = 90 cm³

90/(⅛) = 720 cubes to fill the prism.

volume of bottom layer of cubes = 5×3×½ = 7.5 cm³

7.5/(⅛) = 60 cubes on the bottom layer

Each layer is ½ cm in height

6 cm × (1 layer)/(½ cm) = = 12 layers

perimeter = 2×5 + 2×3 = 16 cm

The nth term of any geometric sequence can be expressed as:

a(n)=ar^(n-1), a(n)=nth term, a=initial term, r=common ratio, n=term number...

We can easily see that the first term, a=-8

The common ratio is 4/-8=-2/4=1/-2=r=-1/2 so the rule is:

a(n)=-8(-1/2)^(n-1) so the tenth term is:

a(10)=-8(-1/2)^(10-1)

a(10)=-8(-1/2)^9

a(10)=1/64

Two squares have areas of 4 cm?
timofeeve [1]

Answer:

1/2

Step-by-step explanation:

First square area = 4cm^2, thus the side length is 2cm

Second square area = 16cm^2, thus the side length is 4cm

This gives a ratio of 2/4, simplifying yields 1/2
