Answer:

-1 and -30 -1+-30=-31

-2 and -15 -2+-15=-17

-3 and -10 -3+-10=-13

-5 and -6 -5+-6=-11

-6 and -5 -6+-5=-11

-10 and -3 -10+-3=-13

-15 and -2 -15+-2=-17

-30 and -1 -30+-1=-31

30 and 1 30+1=31

15 and 2 15+2=17

10 and 3 10+3=13

6 and 5 6+5=11

5 and 6 5+6=11

3 and 10 3+10=13

2 and 15 2+15=17

1 and 30 1+30=31

Step-by-step explanation:

A factor is a number that can be evenly divided by another number without a remainder or decimal. These numbers can all be divided by 30 without resulting in a remainder. After we find the corresponding factor (by dividing by 30), we add them in the resulting column.

b. Find a 99% confidence interval for mean age of ICU patients using the facts that, in the sample, the mean is 57.55 years and

rjkz [21]

Answer:

99% of confidence intervals for mean age of ICU patients

(53.8920 , 61.2079)

Step-by-step explanation:

Explanation:-

Given sample mean $x^{-} = 57.55$

Given standard error is determined by

S.E = $\frac{S.D}{\sqrt{n} }$

Given data standard error = 1.42

99% of confidence intervals for mean is determined by

$(x^{-} - Z_{0.01} \frac{S.D}{\sqrt{n} } , x^{-} + Z_{0.01} \frac{S.D}{\sqrt{n} } )$

$Z_{\frac{\alpha }{2} } = Z_{\frac{0.01}{2} } = Z_{0.05} = 2.576$

$(x^{-} - 2.576 S.E , x^{-} + 2.576 S.E)$

$(57.55 - 2.576X 1.42 , 57.55+ 2.576 X1.42)$

(53.8920 , 61.2079)

Conclusion:-

99% of confidence intervals for mean is determined by

(53.8920 , 61.2079)

Under her cell phone plan, Sydney pays a flat cost of $35.50 per month and

Keith_Richards [23]

The number of gigabytes that Sydney can use while staying within her budget is less than 2.9 gigabytes.

<h3>What are gigabytes?</h3>

gigabytes (GB) – pronounced with two hard Gs – is a unit of storage capacity equal to approximately 1 billion bytes. In decimal form (base 10), a gigabyte is exactly one billion bytes. In binary form, a gigabyte is 230 bytes or 1,073,71,82 bytes. Giga comes from the Greek word for giant. Werner Buchholz is credited with coining the term byte in 1956 and helped design IBM's 7030 Stretch, the first transistorized supercomputer.

gigabytes has been a common unit of measurement for data storage products since the mid-1980s. In recent years, terabytes (TB) have become a more common measure of storage capacity, especially for hard drives and solid-state drives.

Which sequence of transformations takes figure B to its image B'?

marin [14]

Answer:

D. a reflection in the y-axis, followed by a counterclockwise rotation of 270 about the origin

Step-by-step explanation:

Well, the first obvious step is to reflect it across the y-axis. Now, for the next step, since we do not have a 90°-clockwise rotation option, we have to go with something similar to that, which would be a 270°-counterclockwise rotation. If you think about it, since 3 × 90 is 270, and rotating this figure 90° clockwise [one rotation] would go from Quadrant III to Quadrant II, going the other way around [270°counterclockwise (three rotations)] will also go from Quadrant III to Quadrant II [to Quadrant IIII to Quadrant I to Quadrant II].

I am delighted to assist you anytime my friend.
