Answer:

<u>Part (a)</u>

see attached for sample space

<u>Part (b) </u>

\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}

Total number of possible outcomes = 12

\textsf{P(Renae takes an odd-numbered bus)}= \dfrac{9}{12}=\dfrac34

\textsf{P(Renae does not write a letter)}= \dfrac{8}{12}=\dfrac23

\textsf{P(Renae catches no.28 bus then reads a book)}= \dfrac{1}{12}

<u>Part (c)</u>

Her activity does not depend on which bus she takes, as we have been told that once she is on the bus, she randomly selects the activity.  Therefore, the activity selection is independent from the bus selection.

The sample space confirms this as it shows that the probability of the selecting each activity is equally likely for each of the 4 buses.

The endpoints of AB¯¯¯¯¯¯¯¯ are 8 and 16. Find the coordinate of the point P that partitions the segment in the ratio 3 : 1.
Marina CMI [18]

Answer:

The coordinates of the point P is 14.

Step-by-step explanation:

Let point A is at 8 and B is at 16.

P is the point where the line segment in the ratio 3 : 1.

This is also where P is \frac{3}{4} rds the distance from A to B

The total distance is |16 - 8| = 8  

The distance between point AB is 8 units.

\frac{3}{4} of 8 is 6.

So, the point P is 6 units from A .

8 + 6 = 14

P is at 14

Hence, the coordinates of the point P is 14.

This also works if you go 1/3 from B.

-8 is 4 from -4 which is 1/3 of 12.

What is the equation of the line that passes through the point (-5,-6) and has a slope of 3/5?
PtichkaEL [24]

Answer:

y=3/5x-3

Step-by-step explanation:

First, put the slope in point-slope form: y-y1=x(x-x1)

y+6=3/5(x+5)

Distribute 3/5 to (x+5) and simplify.

y+6=3/5x+3

y=3/5x-3

The weight of oranges growing in an orchard is normally distributed with a mean weight of 3.5 oz. and a standard deviation of 0.
Andreas93 [3]

Answer:

(3 oz ; 4oz)

Step-by-step explanation:

Given that :

Mean = 3.5 oz

Standard deviation = 0.5 oz

According to the empirical rule ; 68% is 1 standard deviation from the mean.

Hence, the interval that would represent the middle 68% will be:

(3.5 oz - 0.5 oz) ; (3.5 oz + 0.5oz)

(3 oz ; 4oz)
