How many integral solution(s) is/are there for x if -69 ≤ 7x + 9 ≤ 49?
Answer:
To find the number of integral solutions for x in the given inequality, we can first solve the inequality to find the range of values that x can take on. To do this, we need to isolate the x term on one side of the inequality, so let's start by subtracting 9 from both sides of the inequality:
-69 ≤ 7x + 9 ≤ 49
-9 ≤ 7x ≤ 40
Next, we can divide both sides of the inequality by 7 to isolate the x term:
-9/7 ≤ x ≤ 40/7
The result of this calculation is a range of values for x, but we are looking for the number of integral solutions, which means we need to find the number of whole numbers that x can take on within this range. In this case, we can see that the range of possible values for x is from -1 to 5, and there are 5 whole numbers within this range (-1, 0, 1, 2, 3, 4, 5), so there are 5 integral solutions for x in this inequality.
In general, to find the number of integral solutions for x in an inequality of the form a ≤ bx + c ≤ d, where a, b, c, and d are constants, you can follow these steps:
1.Solve the inequality to isolate the x term on one side, by subtracting c from both sides and then dividing both sides by b. This will give you the range of possible values for x.
2.Count the number of whole numbers within this range to find the number of integral solutions for x.

If f(x)\ =\ x^{2}+3f(x) = x 2 +3 , find f(-2)f(−2) .
The solution for f(-2) in the function f(x) = x² + 3 is 7
How to determine the solution for f(x) in the function?From the question, we have the following equation that can be used in our computation:
f(x) = x 2 +3
To make the equation legible, we need to rewrite it
So, we have the following representation
f(x) = x² + 3
Also from the question, we have
f(-2)
This means that the value of x is -2, and we calculate f(x) when x = -2
Substitute the known values in the above equation, so, we have the following representation
f(-2) = x² + 3
So, we have the following equation
f(-2) = (-2)² + 3

Total Area inclosed between line and Curve:The area where the "area under the curve" is common to both the straight line and the given curve is called the bounding area. Therefore, the area common to both can be found by subtracting the area under line T from the area under curve C. The x constraint for computing the area under the curve can be found by solving the system of equations for the coordinates of the intersection of the line and the curve.
We have given the curve , x = y² and line x = 9 and bounded region is A in above graph of x = y² and line x = 9.
Now, we determine the intersection points of curve and line,
put x = 9 in curve equation we get,

The SUV will be $5,299.13 worth than the car 5 years after their model years.
What is the meaning of rounded to the nearest cent?
Look at the number to the right of the whole cents when rounding money to the closest cent. In this instance, it is 9. Increase the cents by one if the figure is five or above. The cents should remain the same if the number is four or less. Given that 9 is more than 5, $3.299 equals $3.30.
Given that,
The value of a car can be predicted by using the function
f(x)=12,000(0.89)^x
Where x years from its model year.
To find the current value of the car, put x = 0 in the model equation:
f(0)=12,000(0.89)^0
f(0) = 12,000.
To find the value of the car after 5 years, put x = 5 in the model equation:
f(5)=12,000(0.89)^5
f(5) = 6700.871

A basketball player makes 70 % of her free throws. When fouled, she gets to take 2 free throws. Let X represent the number of free throws made in two tries. The probability distribution for the number of free throws she makes in two attempts is summarized in the following table:Number of free throws made 0 1 2Probability 0.09 0.42 0.49The probability that she makes at least one free throw isa.0.67b.0.91c.0.95d.1.00
The probability that she makes at least one free throw is b. 0.91. Probability theory is a branch of mathematics that is used to model and analyze random events.
Probability can be used to predict the likelihood of different outcomes in a wide range of situations, from games of chance to scientific experiments to everyday events. Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, with 0 indicating that an event is impossible and 1 indicating that an event is certain.
To find the probability that the player makes at least one free throw in two attempts, you can subtract the probability that she misses both free throws from 1. The probability that she misses both free throws is 0.09, so the probability that she makes at least one free throw is:
1 - 0.09 = 0.91.
Therefore, the correct answer is 0.91, or choice (b).

A food truck did a daily survey of customers to find their food preferences. The data is partially entered in the frequency table. Complete the table to analyze the data and answer the questions:
Likes hamburgers Does not like hamburgers Total
Likes burritos 29 41
Does not like burritos 54 135
Total 110 205
Part A: What percentage of the survey respondents liked neither hamburgers nor burritos? Show all work. (3 points)
Part B: What is the marginal relative frequency of all customers who like hamburgers? Show all work. (3 points)
Part C: Which category has the lowest joint relative frequency? Show all work. (4 points)
A: 16.09 % of the survey respondents liked neither hamburgers nor burritos
B) 0.65 is the marginal relative frequency.
C) The lowest joint relative frequency of those who like Hamburgers but not burritos.
What is Marginal Frequency?The ratio of a row total's or column total's frequency to the overall frequency of the data is known as marginal relative frequency. It is frequently used to examine broad trends in a single type of data.
Given:
Like Hamburgers Does Not Like Hamburgers Total
Likes burritos 39 38 77
Does not like burritos 95 33 128
Total 134 71 205
A) There are 33 such respondents.
So, percentage is
= 33/205 x 100
= 16.095
B) It will be the ratio of the sum of the customers that like hamburgers to the total number of respondents
So, the ratio is
= 134/205
= 0.65 :1
Part C: For this, we need to find the ratio of all the four data with the total.
Those who like Hamburgers and burritos
= 39/134
Those who like Hamburgers but not burritos
= 95/134
Those who like burritos but not Hamburgers
=38/71
Those who do not like burritos or Hamburgers = 33/71
