Chapter 5, Review Exercise 11 (5 points) One term, about 700 Statistics 2 students at the University of California, Berkeley, we

re asked how many college mathematics courses they had taken, other than Statistics 2. The average number of courses was about 1.1; the SD was about 1.5. Would the histogram for the data look like (i), (ii), or (iii)

Answer:

The histograms are missing, but ill try to answer it nonetheless.

Here we have that the standard deviation is bigger than the mean, this means that we will not see one of the ends (the smaller one) of our bell.

And we have a normal distribution, so we have a gaussian bell.

We will have that the peak of our bell is at the value x =  1.1

The histogram will start with a kinda high value at x = 0, it will get to the maximum at x = 1.1 and it will decrease as a normal bell, and knowing that the distance between the mean value and the point where the bell almost is almost zero, is equal to 3 standard deviations, we can expect to see this at x = 1.1 + 3*1.5 = 1.1 + 4.5 = 5.6

Basic Definitions of Geometry


A collinear set of points is a set of points all of which lie on the same straight line.
A noncollinear set of points s a set of three or more points that do not all line on the same straight
line.
A Line has no end points.
A Ray has one end point.
. Line Segment has two end points
Congruent segments are segments that have the same measure.
The Midpoint of a line segment is a point of that line segment that divides the segment into two
congruent segments.

The Bisector of a line segment is any line, or subset of a line that intersects the segment at the midpoint.
An Angle is a set of points that is the union of two rays having the same endpoint.

The number of bacteria in a culture is expected to grow 82% per hour over the next several hours. The predicted change in the nu
Advocard [28]
If my simplification is valid the answer is:

1.4 % growth each minute

I don’t feel like the representation
P = 120(1.82) is important in this certain problem.

So P the predicted number of bacteria is not practical with this problem.

Use the 82% per hour and divide it by 60 because there are 60 minutes in an hour.

When doing this you find the rate in which bacteria grows which is about 1.4%.

The prediction is about 1.82 percent for 120 something it’s not clarified, but I’m guessing that’s minutes.

So you can prove that the prediction is over the rate in which bacteria grows per minute.

Caitlin makes candles and sells them in her online shop. Tall candles cost $8 each and short candles cost $5 each. last month, s
snow_tiger [21]

Answer:

tall candles = 39

Short candles = 52

Step-by-step explanation:

let tall candles be x

and short candles be y

No. Of candles sold = x + y =91

Money made from candles will be equal to = 8x + 5y = $572

These both are simultaneous linear equations.

x + y =91 ( multiply by 5)

5x + 5y = 455

8x + 5y = $572

Subtract them:

-3x = -117

x = -117/3

x = 39

put value of x in

x + y = 91

39 + y = 91

y = 91 - 39

y = 52

x shows tall candles so they are 39

y shows short candles so they are 52
