Answer:
He swam 1/2 mile more and biked 1 1/4 mile more in July
Step-by-step explanation:
June -- Bike 4 * ( 3 1/4) = 13 miles
Swim 4 * (2 1/2) = 10 miles
July -- Bike 3 * (4 3/4) = 14 1/4 miles
Swim 3 * (3 1/2) = 10 1/2 miles
14 1/4 - 13 = 1 1/4
10 1/2 - 10 = 1/2

A fair coin is tossed n times. For which value of n can the experimental probability of tossing tails equal the theoretical probability?
Answer:
The value of the coin tosses per time in the air
Step-by-step explanation:
The value of n for which the experimental probability of tossing tails can equal the theoretical probability is any even number.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
The theoretical probability of tossing tails in a fair coin is 0.5 or 1/2.
The experimental probability of tossing tails in n trials is the number of times tails appear divided by n.
So, we want to find a value of n such that:
number of times tails appear / n = 0.5
Solving for n:
number of times tails appear = 0.5n
Since the number of times tails appear must be a whole number, n must be even.
This is because if n is odd, then it is not possible to have exactly half the trials result in tails.
For example,
If n=3, the possible numbers of tails that can appear are 0, 1, 2, or 3. Half of 3 is 1.5, which is not a whole number, so it is impossible to have exactly half the trials result in tails.
On the other hand,
If n=4, the possible numbers of tails that can appear are 0, 1, 2, 3, or 4.
Half of 4 is 2, which is a whole number, so it is possible to have exactly half the trials result in tails.
Therefore,
The value of n for which the experimental probability of tossing tails can equal the theoretical probability is any even number.

below:
2.3, 0.3, 7,6.1, 9.7
Give your answer as a decimal.
Answer:
Mean = 5.08

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
[tex] \frac{2.3 + 0.3 + 7 + 6.1 + 9.7}{5} [/tex]

Since segment AC bisects (aka cuts in half) angle A, this means the two angles CAB and CAD are the same measure. I'll refer to this later as "fact 1".
Triangles ABC and ADC have the shared segment AC between them. By the reflexive property AC = AC. Any segment is equal in length to itself. I'll call this "fact 2" later on.
Similar to fact 1, we have angle ACB = angle ACD. This is because AC bisects angle BCD into two smaller equal halves. I'll call this fact 3
----------------------
To summarize so far, we have these three facts
angle CAB = angle CADAC = ACangle ACB = angle ACDin this exact order, we can use the ASA (angle side angle) congruence property to prove the two triangles are congruent. Facts 1 and 3 refer to the "A" parts of "ASA", while fact 2 refers to the "S" of "ASA". The order matters. Notice how the side is between the angles in question.
------------------------
Once we prove the triangles are congruent, we use CPCTC (corresponding parts of congruent triangles are congruent) to conclude that AB = AD and BC = BD. These pair of sides correspond, so they must be congruent in order for the entire triangles to be congruent overall.
It's like saying you had 2 identical houses, so the front doors must be the same. The houses are the triangles (the larger structure) and the door is an analogy to the sides (which are pieces of the larger structure).

The following diagram shows where a road intersects two parallel streets. At
one intersection, ∠2 measures 120°. What are the measures of ∠7 and ∠8 at the
other intersection? How do you know?
Answer:
∠7=120 degrees, ∠8=60 degrees.
Step-by-step explanation:
Since the roads are parallel lines, we can say that angle 4 is equal to 60 degrees, since a line is 180 degrees and 180-120=60.
We can then say that with the corresponding angles theorem, angle 4 is equal to angle 8. Since angle 7 is on the same line, and lines are 180 degrees, we can say that angle 7 is 180-60, or 120 degrees.

Suppose an urn has six balls, three red, two blue, and one yellow. On any draw from the urn, all balls in the urn are equally likely to be drawn. Suppose that two balls are drawn, in sequence without replacement, that is, the second ball is drawn without replacing the first ball in the urn. What is the probability that the second ball drawn is blue
Answer:
1 / 3
Step-by-step explanation:
Number of balls :
Red, R = 3 ; Blue, B = 2 ; Yellow, Y = 1
Total = 6
From two draws without replacement, probability that 2nd draw is blue :
Possibilities :
P(RB) or P(YB) or P(BB)
P(RB) = 3/6 * 2/5 = 6/30
P(YB) = 1/6 * 2/5 = 2 /30
P(BB) = 2/6 * 1/5 = 2 / 30
HENCE,
P(RB) + P(YB) + P(BB)
6/30 + 2/30 + 2/30 = 10/30 = 1/3

have completed 816 miles which is 46% of the trail. Can you find about how many miles for the total trip?
Answer:
1773.91 miles
Step-by-step explanation:
Given data
Completed miles= 816 miles
Percentage completion= 46%
Let the total distance be x
Hence
46% of x= 816
let us find x
46/100*x= 816
0.46x=816
x= 816/0.46
x= 1773.91
Therefore the total distance is 1773.91 miles
