Given: The first triangle has side lengths of 6, 10, 8 and the second triangle has side lengths of 3, 5, 4 such that these two right triangles have identical angle measures but different side lengths.
To choose: the correct option
Dilation refers to a transformation when a figure is reduced or enlarged.

So, Dilation transformation maps the large triangle onto the small triangle
The transformation is because the Dilation.
What is transformation?The geometric transformation is a bijection of a set that has a geometric structure by itself or another set.
Given that the first triangle has side lengths of 6, 10, 8 and the second triangle has side lengths of 3, 5, 4 such that these two right triangles have identical angle measures but different side lengths.
So, we need to identify the type of transformation.
We see that the measures of the sides are decreased by a scale factor of 2.
So we can say there is a dilation,
Dilation refers to a transformation when a figure is reduced or enlarged.
Each side of the large triangle is halved to get the small triangle.
So, Dilation transformation maps the large triangle onto the small triangle.

If Denny (random name) left to another country and he left the Tuesday of this week (June 20) and he left for a month, what day would he be back on? I though July 18 but I’m not sure. Pls help?
Answer:
Step-by-step explanation:
Well, since the length of a month can vary in the number of days, this answer can also vary.
For example, February is only 28 days long, while December is 31 days long.
That being said, the average length of all 12 months is 30.436875 days, so if Denny left to another country on June 20th, he would most likely be back July 19th of July 20th.

Can someone help me with this? Look at the spinner and then the pictures. Use the spinner to match each scenario to right probability.
The spinner and the pictures, you can decide the likelihood of every match going on and healthy every situation to the proper probability.
The probability of an event occurring would be the number of favorable outcomes (i.e. the number of sections on the spinner that correspond to that event) divided by the total number of possible outcomes (i.e. the total number of sections on the spinner).
A spinner is a round system with various sections, every marked with a one of a kind colour or symbol.
Spinners are generally used in chance experiments to simulate random events.
To in shape every state of affairs to the proper probability, you would want to analyze the spinner and the photographs and decide the possibility of every match occurring.
For example,
If the spinner has six equal sections marked with distinctive colors, and there are six pictures, every with a distinctive color, then the likelihood of touchdown on any one colour is 1/6.
Therefore,
The likelihood of matching any photograph to the shade on the spinner is additionally 1/6.
The likelihood of matching a unique photograph to the coloration on the spinner would be 1/8 (1/4 * 1/2).

A pre-election survey showed that two out of every three eligible voters would cast ballots in the county election. There are 390,000 eligible voters in the county. How many people are expected to vote in the election?
The number of people that nare expected to vote in the election is 260,000. people.
How to illustrate the fraction?Simply put, a fraction is a portion of a whole. Mathematically, the number is represented as a quotient with split numerator and denominator. The numerator and denominator of a simple fraction are both integers. On the other hand, a complex fraction has a fraction in either the numerator or the denominator.
In this situation, the pre-election survey showed that two out of every three eligible voters would cast ballots in the county election and there are 390,000 eligible voters in the county.
The number of people expected to vote will be:
= Fraction of expected voters × Total number of people
= 2/3 × 390000
= 2 × 130000
= 260000

a) The probability a person who has eaten snack A before is 59/143.
b) The probability a person who has eaten snack A before is 84/143
What is probability?
Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.
Given that the total number of people that are taken for the event is 572.
The number of people who have eaten snack A before is 236.
The number of people who have not eaten snack A before is 336.
Probability = The number of outcomes of favorable event/ Total number of outcomes
The probability getting a person who has eaten snack A before is
= 236/ 572
= 59/143 [Divide denominator and numerator by 4]
The probability getting a person who has not eaten snack A before is
= 336/ 572

If the average is 85 minutes, then on the seventh day he skated for 115 minutes.
How long he skated the seventh day?For a set of N values {x₁, x₂, ..., xₙ} we define the average as:
A = (x₁ + ... + xₙ)/N
Here we know that for four days, he skated for 1hr + 25min = 85 min
Then for 2 days he skated for 1hr + 10min = 70 min
And the seventh day he skated x minutes.
We know that the average is 85 min, then we can write the equation:
(4*85 + 2*70 + x)/7 = 85
x = 85*7 - 2*70 - 4*85
x = 115

(a) Find the variance of the ages. Round the answer to at least four decimal places.
The variance of the ages is
Considering the given discrete distribution, the variance of the ages is of 1.5844.
What is the mean and the variance of a discrete distribution?The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.The variance is given the sum of the difference squared between each outcome and the mean, multiplied by it's respective probability.In this problem, considering the distribution given in the table, the mean is given by:
\(E(x) = 13(0.09) + 14(0.22) + 15(0.25) + 16(0.28) + 17(0.15) + 18(0.02) = 15.39\)
Hence, the variance is given as follows:
\(Var(x) = 0.09(13-15.39)^2 + 0.22(14-15.39)^2 + 0.25(15-15.39)^2 + 0.28(16-15.39)^2 + 0.15(17-15.39)^2 + 0.02(13-15.39)^2 = 1.5844\)
