The car is 7 feet long and the model is 16 inches long, the ratio of the length of the car to the length of the model is, 21:4 So Option D is correct
What is the ratio?A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.
Given that,
The car is 7 feet long
The model is 16 inches long
The ratio of the length of the car to the length of the model = ?
It is known that,
1 feet = 12 inches
Now, converting length of car into inches
⇒ 7 feet = 7×12 inches = 84 inches
So, Ratio of lengths
⇒ 84/16
⇒ 21/4
Hence, the ratio is 21:4

100 tourists had visited both the Magic Kingdom and LEGOLAND
82 tourists had visited both the Magic Kingdom and Universal Studios
76 tourists had visited both LEGOLAND and Universal Studios
12 tourists had visited all three theme parks
68 tourists did not visit any of these theme parks
How many tourists only visited the LEGOLAND (of these three)?
44 tourists only visited LEGOLAND (of these three).
Solving for the tourists only visited the LEGOLAND only:Let's call the number of tourists who visited only LEGOLAND x.
From the information given, we know that:
258 tourists had visited the Magic Kingdom
299 tourists had visited Universal Studios
100 tourists had visited both the Magic Kingdom and LEGOLAND
82 tourists had visited both the Magic Kingdom and Universal Studios
76 tourists had visited both LEGOLAND and Universal Studios
12 tourists had visited all three theme parks
68 tourists did not visit any of these theme parks
We can calculate x as follows:
x = number of tourists who visited LEGOLAND only
number of tourists who visited LEGOLAND - number of tourists who visited LEGOLAND and Magic Kingdom - number of tourists who visited LEGOLAND and Universal Studios + number of tourists who visited all three parks
= 100 - 82 - 76 + 12
= 44

Determine if the sequence is arithmetic. If it is, find the common difference, the 52nd term, the
explicit formula, and the recursive formula.
Hence Sequences 4, 16, 36, 64,.. are not arithmetic, however 40, 30, 20, 10,... are, with a common difference of -10 and the 52nd term being -490.
what is arithmetic progression ?An arithmetic progression is defined as a constant discrepancy between terms that follow one another through a series. For instance, the number sequence 5, 7, 9, 11, 13, and 15 is an example of either an exponential manner with a limitation of two. A progression with a set tolerance between any consecutive numbers is referred to as a "arithmetic progression" (A.P.). Two types of mathematical progression are possible: series in mathematics with a finite length A finite geographic progression is a serie with a finite number of terms. The early, delayed, tolerance, and frequency of terms may all be calculated using the terms in the series.
given
First succession
4, 16, 36, 64,
The common difference must be the same for it to be considered AP.
It is not AP since 16 - 4 ≠ 36 - 16.
Second succession;
40, 30, 20, 10, ...
common distinction =30 - 40 = 20 - 30 = 10 - 20 = -10
As a result, it will be an AP because the common difference is -10 and the same.
Now, The nth phrase of AP equals a plus (n - 1) d, where d is a typical difference and an is the initial term.
So, 52nd term = 40 + (52 - 1) (-10), which is -490.
Hence Sequences 4, 16, 36, 64,.. are not arithmetic, however 40, 30, 20, 10,... are, with a common difference of -10 and the 52nd term being -490.

Given is that Elizabeth is thinking of a two - digit number. When the tens digit is subtracted from the ones digit, the difference is 2. One-fifth of the number is 1 less than the sun of the digits.
Let the number be (xy).
We can write the two digit number as -
xy = 10x + y ... Eq { 1 }
Now, it is given that when the tens digit is subtracted from the ones digit, the difference is 2. We can write -
y - x = 2 ... Eq { 2 }
Also, one - fifth of the number is 1 less than the sun of the digits. We can write -
(1/5)(10x + y) = (x + y) - 1 ... Eq { 3 }
Now, from eq { 1 } and eq { 2 }, we have -
y - x = 2
y = x + 2
and
(1/5)(10x + y) = (x + y) - 1
(1/5)(10x + x + 2) = (x + x + 2) - 1
(1/5)(11x + 2) = 2x - 1
11x + 2 = 10x - 5
x = - 7
y = -5
So, the number would be -
xy = 35
Therefore, the two digit number is 35.

Lydia has money in two savings accounts. One rate is 12% and the other is 13%. If she has $850 more in the 13% account and the total interest is $388, how much is invested in each savings account?
Lydia invested an amount of $1110 in the 12% savings account and $1960 in the 13% savings account.
Let's assume the amount invested in the 12% savings account "x". Then, the amount invested in the 13% savings account would be "x + 850".
The total interest earned is $388, so we can write the following two equations to represent the interest earned in each account:
0.12x + 0.13(x + 850) = 388
Expanding the second equation, we get:
0.12x + 0.13x + 110.5 = 388
Combining like terms and simplifying, we get:
0.25x = 277.5
Dividing both sides by 0.25, we get:
x = 1110
So, she invested $1106 in the 12% savings account and $1110 + 850 = $1960 in the 13% savings account.

What do you mean by Probability?Probability is a branch of mathematics that deals with the study of random events and their likelihood of occurring. It provides a framework for understanding the uncertainty and unpredictability of real-world events and helps to make informed decisions based on data and evidence.
The basic concept of probability is the idea that every event has a numerical value between 0 and 1, representing the likelihood of the event occurring. An event with a probability of 1 is considered certain to occur, while an event with a probability of 0 is considered impossible to occur. Events with probabilities between 0 and 1 are considered uncertain, and their likelihood of occurrence can be described using a probability distribution.
There are different methods for calculating probabilities, including classical probability, which assumes that all outcomes are equally likely, and empirical probability, which is based on actual observations of real-world events. The concept of conditional probability is also important, as it allows us to calculate the likelihood of an event occurring given the occurrence of another event.
Probability is widely used in many different fields, including science, engineering, finance, and medicine. In science, it is used to model and understand complex systems, while in engineering it is used to design and test new technologies. In finance, it is used to evaluate investments and make informed decisions, while in medicine it is used to assess the risk of diseases and evaluate the effectiveness of treatments.
