Answer:

P(Red) = 0.44

Step-by-step explanation:

There are 3 (mutually exclusive) ways to get red. The probability of red is the sum of the probabilities of the different ways to get there:

P(red) = (0.35)(0.6) + (0.45)(0.2) + (0.20)(0.7) = 0.21 + 0.09 + 0.14 = 0.44

The probability a player will select a red ball is 0.44.

Answers

Answer:

ab = 24

so ac is half, so

ac = 12

and the radius is 13,

draw a line from a to o

and its tall will be 13 because it is the radius and o is the center

now use Pythagoras rule

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

put numbers

[tex] {12}^{2} + {b}^{2} = {13}^{2} [/tex]

and solve for b

b = 5

and that is the side we want

What are arithmetic Operations?

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the given data in the question,

Distance (d) traveled by the horse = 0.5 miles

Time (t) taken by the horse to cover the distance = 1.25 minutes

Then, the speed of the horse will be,

[tex]Speed=\frac{Distance}{Time}[/tex]

s = 0.5/1.25

s = 0.4 miles/minute.

Gallant is president of Kranbrack Corporation, a company whose stock is traded on a national exchange. In a meeting with investment analysts at the beginning of the year, Gallant had predicted that the companys earnings would grow by 20% this year. Unfortunately, sales have been less than expected for the year, and Gallant concluded within two weeks of the end of the fiscal year that it would be impossible to report an increase in earnings as large as predicted unless some drastic action was taken. Accordingly, Gallant has ordered that wherever possible, expenditures should be postponed to the new yearincluding canceling or postponing orders with suppliers, delaying planned maintenance and training, and cutting back on end-of-year advertising and travel. Additionally, Gallant ordered the companys controller to carefully scrutinize all costs that are currently classified as period costs and reclassify as many as possible as product costs. The company is expected to have substantial inventories at the end of the year.1. Why would reclassifying period costs as product costs increase this periods reported earnings?2.
