Answer:
According to PEDMAS , We first simplify the PARENTHESES
[5 · (2 – 4)] = [5· -2] = -10
Step-by-step explanation:
Given expression [–23 – [5 · (2 – 4)]] ÷ 32
We have to find the first step to simplify the given expression.
We apply PEDMAS
P stands for PARENTHESES
E stands for EXPONENTS
D stands for DIVIDE
M stands for MULTIPLY
A stands for ADDITION
S stands for SUBTRACTION.
So, according to PEDMAS , We first simplify the PARENTHESES
Thus, [5 · (2 – 4)] = [5· -2] = -10

The equation for the line of best fit for a data set is y = 2x + 1.5. If the point (1, 4) is in the data set, what is the residual of 1? 0.5 3.5 4.0 7.5
Answer: First option is correct.
Step-by-step explanation:
Since we have given that
[tex]y=2x+1.5[/tex]
If the point (1,4) is in the data set.
we need to find the residual of 1.
At x = 1,
[tex]y=2x+1.5\\\\y=2\times 1+1.5\\\\y=2+1.5\\\\y=3.5[/tex]
So, At x = 1, the value of y = 3.5
As we know that
[tex]Residual\ value=Estimate\ value-Actual\ value\\\\Residual\ value=4-3.5\\\\Residual\ value=0.5[/tex]
Hence, The residual of 1 is 0.5.
Thus, First option is correct.

A box contains 3 blue and 2 red pens while another box contains 2 blue and 5 red pens. a pen drawn at random from one of the boxes turns out to be blue. what is the probability that it came from the first box
The probability of getting blue from the first box is 3/5.
Given that, a box contains 3 blue and 2 red pens while another box contains 2 blue and 5 red pens.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favourable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.
Probability(Event) = Favorable Outcomes/Total Outcomes = x/n.
The probability of getting blue from the first box:
The number of favourable outcomes = 3 and the number of total outcomes =5
So, P(E) = 3/5
The probability of getting blue from the second box:
The number of favourable outcomes = 2 and the number of total outcomes =7
So, P(E) = 2/7
Therefore, the probability of getting blue from the first box is 3/5.

b. a population is a set of data.
c. a population is the set of all the properties that can be assigned to any people or objects in a given sample.
d. a population is a group that exhibits characteristics typical of those possessed by the target sample?
The term population is the set containing all the people or objects whose properties are to be described. Hence, option (a) is correct.
What is Population?A community is a distinct group of people, creatures, or other objects that can be recognized for the purposes of data gathering and analysis by at least one shared trait.
The majority of the time, data is collected from samples in order to learn more about huge populations. For instance, market researchers might randomly contact a small percentage of the town's subscribers to major carrier services who were born between 1980 and 2004 if they wanted to obtain representative statistics for Millennial consumers of mobile phones who did not have a landline in New York City (the population).

Park rangers released 12 fish into a pond in year 0. Each year, there were twice as many fish as the year before. How many fish were there after x years? Write a function to represent this scenario.
Answer: The function would be,
[tex]f(x)=12(2)^x[/tex]
Step-by-step explanation:
Given,
Park rangers released 12 fish into a pond in year 0,
Thus, the initial number of fish = 12,
Also, there were twice as many fish as the year before,
⇒ After 1 year the number of fishes = 2(12) = 12(2),
Similarly,
After 2 years = 2(12(2))= 12(2)²,
After 3 years = 2(12(2)²) = 12(2)³,
................, so on,....
Thus, the number of fishes after x years would be,
[tex]12(2)^x[/tex]
Let f(x) represents the number of fish after x years,
[tex]\implies f(x) = 12(2)^x[/tex]
Which is the required function that the given scenario.

The height of a triangular road sign is 1 inch shorter than twice its base. if the area of the sign is 60 in.2, which equation could be used to find the base (b) of the sign?
The equation that can be used to find the base of the triangular road sign is 60 = (b * (2b - 1)) / 2.
Explanation:Let's assume that the base of the triangular road sign is represented by b. According to the problem, the height of the sign is 1 inch shorter than twice its base, which can be written as:
height = 2b - 1
The area of a triangle can be calculated using the formula Area = (base * height) / 2. Substituting the given values into the formula, we get:
60 = (b * (2b - 1)) / 2
This equation can be used to find the base, b, of the sign.

what is the largest possible product of two odd integers whose sum is 42?
The largest possible product of two odd integers whose sum is 42 is 437, obtained from multiplying 19 by 23.
The question asks for the largest possible product of two odd integers whose sum is 42. To find this, we should split 42 into two odd numbers that are as close to each other as possible because the product of two numbers that are close together will be higher than the product of a pair that has a larger difference.
If we divide 42 by 2, we get 21, which is not an even integer, so we need to adjust the numbers by 1. So the two odd numbers closest to each half of 42 are 21 and 21. However, we can't have them both be the same number since we're looking for two integers, so we adjust one up and one down by 1, resulting in 20 and 22. To ensure both numbers are odd, we will subtract 1 from the first number and add 1 to the second number, giving us 19 and 23 as the two odd integers that sum to 42.
The product of 19 and 23 is 19 × 23 = 437, which is the largest possible product for two odd integers that add up to 42.
What is the recursive formula for the sequence 3, 12, 48, 192, 768...?
The given sequence is a geometric sequence. Each term in the sequence multiplies by 4 to obtain the next. Therefore, the recursive formula for the sequence is an = 4 * an-1.
Explanation:The given sequence is: 3, 12, 48, 192, 768, and so on. Looking at the sequence, we can see that each term is multiplied by 4 to get the next term. So, the sequence is a geometric sequence. The recursive formula for a geometric sequence is given by: an = r * an-1, where an is the nth term, r is the common ratio, and an-1 is the previous term. In this case, r equals 4 (since we are multiplying each term by 4 to get the next term). Thus, "the recursive formula for this geometric sequence is: an = 4 * an-1".
