what is 2x – 3 < 7 and 5 – x ≤ 8?
Answer:
Result for Inequality expression 1:
[tex]x < 5[/tex]
Result for Inequality expression 2:
[tex]x \geq -3[/tex]
Step-by-step explanation:
-Inequality expression 1:
[tex]2x - 3 < 7[/tex]
-Inequality expression 2:
[tex]5 - x \leq 8[/tex]
-Solve inequality expression 1:
[tex]2x - 3 < 7[/tex]
[tex]2x - 3 + 3 < 7 + 3[/tex]
[tex]2x < 10[/tex]
[tex]\frac{2x}{2} < \frac{10}{2}[/tex]
[tex]\boxed {x < 5}[/tex]
-Solve inequality expression 2:
[tex]5 - x \leq 8[/tex]
[tex]5 - 5 - x \leq 8 - 5[/tex]
[tex]- x \leq 3[/tex]
[tex]\frac{-x}{-1} \leq \frac{3}{-1}[/tex]
[tex]\boxed {x \geq -3}[/tex] (inequality sin changed by divide by a negative integer or variable)
The following inequality represents the solution set -
-3 ≤ x < 5.
We have the following compound inequality -
2x – 3 < 7
5 – x ≤ 8
We have to solve for x.
Define Compound Inequality. What are its types ?A compound inequality (or combined inequality ) is two or more inequalities joined together with OR or AND. There are two types of compound inequalities in the form of conjunction problems and disjunction problems.
According to the question, we have -
1st Inequality -2x – 3 < 7
Add 3 on both sides -
2x - 3 + 3 < 7 + 3
2x < 10
Divide both sides by 2, we get -
x < 5
2nd Inequality5 – x ≤ 8
Subtract 5 on both sides -
5 - x - 5 ≤ 8 - 5
- x ≤ 3
Multiply both sides by '-1' -
x ≥ -3
Combining both solutions, we can write it as -
-3 ≤ x < 5
Hence, the following inequality represents the solution set -
-3 ≤ x < 5

Step-by-step explanation:
You must first do 4(3)+11 to equal 23
Answer:
23
Step-by-step explanation:
If x = 3, then that means you must replace x with 3.
But it doesn't mean that the number will be 43, it will become into 4x3+11.

Answer:
1. MO=14 units
2. M=3
3.X=5
Step-by-step explanation:
1. The length is just how many units between each point
2. Find the average of the two points (use absolute value)
(|-4|+10)÷2=(4+10)÷2=14÷2=7, the midpoint is 7 units from each endpoint. so 10-7=3
3. the length of the line ac=10x, the parts are 12 and 8x-2 set up an equation
10x=12+8x-2 combine like terms
2x=10 divide both sides by 2
x=5
Step-by-step explanation:
1. 10-(-4)
10+4=14
3. AB+BC=AC
12+8X-2=10x
10+8x=10x
10= 10x-8x
10=2x
5=x
therefore x=5

Answer:
D. 96 degrees
Step-by-step explanation:
In a parallelogram, opposite angles must add up to 180
3x + x + 52 = 180
4x = 128
x = 32
∠B = 3x
∠B = 3(32)
∠B = 96
Answer:
96
Step-by-step explanation:
3x + x + 52 = 180
4x = 128
x = 32
∠B = 3x
∠B = 3(32)
∠B = 96
When 1480 is divided into 12 equal parts, the remainder is 4. What is a correct way to write the quotient? (3 points)
Answer:
Depending on what type of math class you are in, or how your teacher taught it, it could be either 12 R:4 or 12 + 1/370.
Step-by-step explanation:
Remainders can be written in two ways, R: [remainder] or the whole number quotient + [remainder number]/[dividend]. For this problem you would have to simplify 4/1480 to 1/370 because 1480/4 equals 370. So, your final answer would be 12 + 1/370 or 12 R:4.

which subset of the rational numbers best describes the dimension of a rectangle ?
A. whole numbers
B. integers
C. negative integers
D. positive rational numbers
The best subset that describes the dimension of a rectangle is the set of all rational numbers.
We have,
The dimension of a rectangle refers to its length and width, which are usually measured in units such as feet or meters.
These measurements can be any real number, including irrational numbers such as √2 or π.
Now,
The only subset of the rational numbers listed in the answer choices is the positive rational numbers, which are the set of all numbers that can be expressed as a ratio of two integers where the denominator is not zero and the numerator and denominator are both positive.
While the dimensions of a rectangle can be positive rational numbers, they can also be negative rational numbers or zero, as long as they satisfy the properties of a rectangle (e.g., length and width are both positive, and the angles are right angles).
Therefore, the answer is not D.
Also, whole numbers and integers are not sufficiently precise to describe the dimensions of a rectangle, as they do not include fractions or decimals.
The only subset of rational numbers that include all possible values for the dimensions of a rectangle is the set of all rational numbers, which includes positive, negative, and zero rational numbers, as well as fractions and decimals.
Therefore,
The best answer is "the set of all rational numbers".

In proof testing of circuit boards, the probability that any particular diode will fail is . Suppose a circuit board contains diodes. How many diodes would you expect to fail, and what is the standard deviation of the number that are expected to fail? What is the (approximate) probability that at least four diodes will fail on a randomly selected board? If five boards are shipped to a particular customer, how likely is it that at least four of them will work properly? (A board works properly only if all its diodes work.)
Complete Question
In proof testing of circuit boards, the probability that any particular diode will fail is 0.01.
Suppose a circuit board contains 200 diodes. How many diodes would you expect to fail, and what is the standard deviation of the number that are expected to fail? What is the (approximate) probability that at least four diodes will fail on a randomly selected board?If five boards are shipped to a particular customer, how likely is it that at least four of them will work properly? (A board works properly only if all its diodes work)
Answer:
The number of diode expected to fail is
[tex]\mu =2 [/tex]
The standard deviation is
[tex]\sigma = 1.407 [/tex]
The probability that at least four diodes will fail on a randomly selected board is
[tex]P(X \ge 4) = 0.1419[/tex]
Step-by-step explanation:
Generally the testing follows a binomial distribution because
1 The number of trials is finite
2 There is only two outcomes( which (a) A diode fail (b) a diode does not fail)
3 The each individual trial is independent of each other.
4 The chances of success is constant for every trial
From the question we are told that
The probability that a diode will fail is [tex]p = 0.01[/tex]
The sample size is n = 200
Generally the number of diode expected to fail is mathematically represented as
[tex]\mu = n * p[/tex]
=> [tex]\mu = 200 * 0.01 [/tex]
=> [tex]\mu =2 [/tex]
Generally the standard deviation is mathematically represented as
[tex]\sigma = \sqrt{ np * (1 - p)}[/tex]
=> [tex]\sigma = \sqrt{ 200* 0.01 * (1 - 0.01 )}[/tex]
=> [tex]\sigma = 1.407 [/tex]
Generally the probability that at least 4 diode will fail is mathematically represented as
[tex]P(X \ge 4) = 1 - P(X < 4 )[/tex]
Generally
[tex]P(X < 4 ) = P(X = 0 ) + P(X = 1) + P(X = 2) + P(X = 3)[/tex]
=> [tex]P(X < 4 ) = ^nC_0 p^0 * (1-p)^{n-0} +^nC_1 p^1 * (1-p)^{n-1}+^nC_2 p^2 * (1-p)^{n-2}+ ^nC_3 p^3 * (1-p)^{n-3} [/tex]
=> [tex]P(X < 4 ) = ^{200}C_0 p^0 * (1-0.01)^{200-0} +^{200}C_1 (0.01)^1 * (1-0.01)^{200-1}+^{200}C_2 (0.01)^2 * (1-0.01)^{200-2}+ ^{200}C_3 (0.01)^3 * (1-0.01)^{200-3} [/tex]
=> [tex]P(X < 4 ) = 0.134 + 0.2707 + 0.2727 + 0.1814[/tex]
=> [tex]P(X<4) = 0.8581[/tex]
So
[tex]P(X \ge 4) = 1 -0.8581)[/tex]
=> [tex]P(X \ge 4) = 0.1419[/tex]
