Answer:

ABC are the marked vertices (points) of a triangle. They join each line ie) A to B= AB A to C= AC B+C=BC. We can when working on combined lines and shapes call the exterior vertices away from the triangle D and E when making reference to finding measurements of adjoining shapes/lines, but not to ABC. We can also use AB to determine the midway point as a independent or alternative use.

We usually see A on the opposite point of a right angle.

HELP. there are 45 coins consisting of nickels, dimes and quarter making a total of 7 dollars. the number of dimes exceeds the n

Answer:

Step-by-step explanation:

Let n, d, q represent the numbers of nickels, dimes, and quarters, respectively. Then we have ...

n + d + q = 45

5n +10d +25q = 700

n -d = -5

Using n=d -5, we can substitute into the first two equations:

(d -5) +d + q = 45

2d +q = 50 . . . . add 5, collect terms [eq4]

5(d -5) +10d +25q = 700

15d +25q = 725 . . . . . . . . . . add 25, collect terms [eq5]

Multiplying [eq4] equation by 3 and subtracting that from 2/5 of [eq5], we have ...

(2/5)(15d +25q) -3(2d +q) = (2/5)(725) -3(50)

6d +10q -6d -3q = 290 -150

7q = 140 . . . . . . simplify

q = 20 . . . . . . . . divide by 7

There are 20 quarters.

Tyson has two movie tickets and wants to randomly select one of six friends to go with him. He rolls a six-sided die to make his

GarryVolchara [31]

Answer:

The relative frequency of rolling a particular number can be calculated using the formula

relative frequency , where f is the actual frequency of an event and n is the number of times the experiment is performed. This experiment had the following results:

The relative frequency of rolling a 1 is 0.2.

The relative frequency of rolling a 2 is about 0.23.

The relative frequency of rolling a 3 is about 0.13.

The relative frequency of rolling a 4 is 0.15.

The relative frequency of rolling a 5 is 0.15.

The relative frequency of rolling a 6 is about 0.13.

The relative frequencies of rolling 1, 2, 3, 4, 5, and 6 are quite similar. So, the relative frequency is a good predictor of the theoretical probability.
