Step-by-step explanation:
Two cyclists start from the same point at the same time and move in opposite directions. One cyclist is traveling at 7 mph, and the other cyclist is traveling at 11 mph. After 30 min, how far apart are the two cyclists? mi Need Help? Read it Watch
Given parameters:
Speed of Cyclist 1 = 7mph
Speed of Cyclist 2 = 11mph
Time of travel = 30min = 0.5hr(60min = 1hr)
Unknown:
Distance separating them = ?
To solve this problem, we must understand that speed is the distance per unit time traveled.
Mathematically;
Speed = [tex]\frac{Distance}{Time}[/tex]
Now we are to find the distance separating the two cyclists;
Distance = speed x time
To find the distance separating the two cyclists, find the sum of their individual distances covered.
Distance separating them = Distance covered by cyclist 1 + Distance covered by cyclist 2
Now input the parameters;
Distance of separation = (7 x 0.5) + (11 x 0.5) = 3.5 + 5.5 = 9miles
The distance separating them is 9miles

A presidential candidate plans to begin her campaign by visiting the capitals in 3 of 42 states. What is the probability that she selects the route of three specific capitals?
Answer as a fraction = 1/68880 which is exact
Answer in decimal form = 0.0000145 which is approximate
=======================================================
Explanation:
Let's call these three cities A, B, and C
There is only one order ABC out of 42*41*40 = 68,880 different possible three city routes to pick from.
So the probability is 1/68880
If you want the answer in decimal form, then use your calculator to find
1/68880 = 0.0000145 approximately
Using the probability concept, it is found that there is a 0.000087 = 0.0087% probability that she selects the route of three specific capitals.
-------------------------
A probability is the number of desired outcomes divided by the number of total outcomes.The order in which the capitals are chosen is not important, which means that the combination formula is used to find the number of total outcomes.Combination formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this problem:
1 desired outcome.The total number of outcomes is a combination of 3 from a set of 42, thus:[tex]T = C_{42,3} = \frac{42!}{3!39!} = 11480[/tex]
The probability is:
[tex]p = \frac{1}{11480} = 0.000087[/tex]
0.000087 = 0.0087% probability that she selects the route of three specific capitals.

17. You want to test a new athlete's-foot treatment. You test men and women separately, randomly dividing them into treatment and control groups. The treatment groups receive the new treatment and the control groups receive an inert powder that resembles the treatment. Neither the subjects nor the test administrators know which groups receive the treatment and which groups receive the inert powder. At the end of the experiment, all subjects are asked to rate their degree of relief from athlete's foot. These scores are compared between groups. Which of the following groups of elements were present in this study?
a. Randomization, blocking, placebo, comparative, double-blind
b. Comparative, randomization, placebo, blind
c. Double-blind, randomization, comparative, placebo
d. Randomization, stratified sample, placebo, blind, treatment
e. Double-blind, control, observational, blocking
Answer:
a. Randomization, blocking, placebo, comparative, double-blind
Step-by-step explanation:
1. Randomization is the process of assigning the subjects in an experiment to any of the treatment groups. This was applied in this experiment when the researcher randomly divided the men and the women into treatment and control groups.
2. Blocking is introduced in an experiment in order to remove nuisance factors. The researcher introduced blocking in this experiment when he divided the men and women on the basis of gender.
3. The Placebo is the inert powder that was given to a group. It has no effect on the participants who receive it.
4. Comparative research compares the result from two groups. This is seen in this research hen the researcher compares the scores between the groups.
5. A double-blind experiment is one where neither the subjects nor the test administrators know which groups receive a treatment. This factor is present in this test.

Find all missing angles
Answer:
m<1 = 51 degrees
m<2 = 18 degrees
m<3 = 123 degrees
m<4 = 39 degrees
Step-by-step explanation:
To solve this problem, let's first try to find the measure of angle 1.
To do this, we must remember that the sum of the interior angles of a triangle must equal 180 degrees. Using this knowledge, we can set up the following equation:
72 + 57 + m<1 = 180
Our first step in solving this equation is to simplify the left side by adding together the two constant terms.
129 + m<1 = 180
Next, we can subtract 129 from both sides of the equation.
m<1 = 51 degrees
Now, we can solve for angle 2.
We can see that angle 2 and the angle measuring 72 degrees together make a right angle, which is 90 degrees. From this observation, we can set up the following equation:
m<2 + 72 = 90
To solve, we subtract 72 from both sides of the equation.
m<2 = 18 degrees
Now, we can solve for angle 3.
We can see from the diagram that angle 3 and the angle measuring 57 degrees are supplementary. This means that their sum should equal 180 degrees, and the two angles together make a straight line. This lets us set up the following equation:
m<3 + 57 = 180
To solve, we subtract 57 from both sides of the equation.
m<3 = 123 degrees
Finally, we can solve for angle 4.
We can solve for angle 4 using the same strategy we used to solve for angle 1. Our equation for angle 4 is as follows:
m<2 + m<3 + m<4 = 180
18 + 123 + m<4 = 180
Let's first simplify the left side of the equation.
141 + m<4 = 180
We can subtract 141 from both sides of the equation as our next step.
m<4 = 39 degrees
Therefore, the correct answers are m<1 = 51 degrees, m<2 = 18 degrees, m<3 = 123 degrees, and m<4 = 39 degrees.

The sum of two consecutive even numbers is 30. How can you solve for the 2 numbers?
Answer:
14 and 16.
Step-by-step explanation:
We know that two consecutive even numbers is 30.
Let's let n be any number.
Then the first even number must be 2n.
This is because n can be any number, either even or odd. However, if we multiply it by 2, this ensures that 2n is even. Remember that any number multiplied by 2 yields an even number.
Therefore, the consecutive even number will be (2n+2). Not (2n+1), because that gives an odd number.
We know that they sum to 30. So, we can write the following equation.
[tex](2n)+(2n+2)=30[/tex]
And we solve from there:
[tex]4n+2=30\\\Rightarrow4n=28\\\Rightarrow n=7[/tex]
So, the value of n is 7.
Therefore, the first even number is 7(2)=14.
And the consecutive even number is 16.
