The solution of the inequality 1 1/8 + b ≥ 7/16 will be;
⇒ - 11/16 ≤ b
What is Inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
The inequality is,
⇒ 1 1/8 + b ≥ 7/16
Now,
Solve the inequality as;
The inequality is,
⇒ 1 1/8 + b ≥ 7/16
Solve for b as;
⇒ 9/8 + b ≥ 7/16
Subtract 9/8 as,
⇒ 9/8 + b - 9/8 ≥ 7/16 - 9/8
⇒ b ≥ (7 - 18) / 16
⇒ b ≥ - 11/16
⇒ - 11/16 ≤ b
Thus, The solution of the inequality 1 1/8 + b ≥ 7/16 will be;
⇒ - 11/16 ≤ b

Probability = 1/52
Hope it helps....... pls mark as brainliest
This is the likelihood or chance that an event will occur. The probability of choosing the "6 of hearts" is 1/52
What is probabiility?This is the likelihood or chance that an event will occur. Mathematically;
Probability =expected/total
Since a standard deck of card contains 52 cards, hence total outcome is 52 cards
No. of 6 of hearts is 1 from the deck of cards
Pr(choosing 6 of hearts) = 1/52
Hence the probability of choosing the "6 of hearts" is 1/52

Step-by-step explanation:
The length of the tangent AB is [tex]\sqrt{2a^{2}+2b^{2} }[/tex] if the radii of the largest circle is a and the radii of the smallest one is b.
What is the tangent?It is a line that touches a single point on the circle.
How to determine the length of that tangent?Firstly we have to draw a perpendicular from O to the radii of the smallest circle. In this way AOLB becomes a rectangle. We let the point where the bisector intersect the radii as L.
OA=a
Lb=a also
O'L=b-a
In triangle OLO' we use pythagoras to calculate the value of OL which wil then equal to AB so,
OL=[tex]\sqrt{(b-a)^{2}+(a+b)^{2} }[/tex]
=[tex]\sqrt{2a^{2}+2b^{2} }[/tex]
It will be the length of AB also.

The sum of digits in a two-digit number is 14. If you double the reversed number and add the result to the original number, the sum would be 222. Find the original number
Answer:
Original number is 86
Step-by-step explanation:
Original: 10x + y
Double reversed: 2(10y + x)
Constraints:
x + y = 14 ===> x = 14 - y
2(10y + x) + 10x + y = 222 ===> 21y + 12x = 222
Substitution to find y:
21y + 12x = 222
21y + 12(14 - y) = 222
21y + 168 - 12y = 222
9y + 168 = 222
9y = 54
y = 6
Substitution to find x:
x = 14 - y
x = 14 - 6
x = 8
Original: 10x + y
10(8) + (6)
80 + 6
86

If f(3) = 2, find f^-1(2)
Help pls
Answer:
[tex]f^{-1}[/tex](2) is 3
Step-by-step explanation:
In the function f(x) = y, its inverse is f(y) = x
So to find the inverse of a function switch x and y
Example:
In f(1) = 2, x = 1 and y = 2
Its inverse is [tex]f^{-1}[/tex](y) = x
Then, [tex]f^{-1}[/tex](2) = 1
Let us use this rule to solve the question
∵ f(3) = 2
∴ x = 3 and y = 2
→ To find its inverse switch x and y
∵ [tex]f^{-1}[/tex](y) = x
∴ [tex]f^{-1}[/tex](2) = 3

point y is between the points X and Z. if XY =3x- 4 , YZ = 2x +3, and XZ =24
Answer:
The numerical value of XY is 11
The numerical value of YZ is 13
Step-by-step explanation:
Given that
XY =3x- 4 , YZ = 2x +3, and XZ =24
As Y is between the points X and Z so the sum of length of XY and YZ will be equal to the length of XZ. Putting this in mathematical form
[tex]XY+YZ = XZ[/tex]
Putting the values
[tex](3x-4) + (2x+3) = 24\\3x-4+2x+3 = 24\\5x-1 = 24\\5x = 24+1 \\\frac{5x}{5} = \frac{25}{5}\\x = 5[/tex]
Now
[tex]XY = 3x-4 = 3(5)-4 = 15-4 = 11[/tex]
[tex]YZ = 2x+3 = 2(5)+3 = 10+3 = 13[/tex]
Hence,
The numerical value of XY is 11
The numerical value of YZ is 13

Explain why the The Communative Property of Addition is different from The Communative Property of Multiplication.
Answer: What is the commutative property of addition? To “commute” means to move around or travel. According to the commutative property of addition, changing the order of the numbers we are adding, does not change the sum. Here's an example of how the sum does NOT change, even if the order of the addends is changed and The commutative property of multiplication
states that when two numbers are being multiplied, their order can be changed without affecting the product.

A company sells 14 types of crackers that they label varieties 1 through 14, based on spice level. What is the probability that the purchase results in a selection of a cracker with an odd number, or a number greater than 11?
Answer:
The required probability is [tex]\mathit{\frac{9}{14}}[/tex]
Step-by-step explanation:
Probability: Rule of Addition
The probability that Event A or Event B occurs is equal to the probability that Event A occurs plus the probability that Event B occurs minus the probability that both Events A and B occur. It can be calculated as follows:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
There are 14 types of crackers the company sells, numbered from 1 to 14. The sample space for purchasing one cracker is:
[tex]\Omega=\{1,2,3,4,5,6,7,8,9,10,11,12,13,14\}[/tex]
There are n=14 possible choices.
The favorable cases for a cracker with an odd number are:
A = {1,3,5,7,9,11,13}
There are 7 favorable cases.
The favorable cases for a cracker with a number greater than 11 are:
B = {12,13,14}
There are 3 favorable cases.
The cases which are common to both events are:
A ∩ B= {13}
There is 1 case.
The probability of each event is:
[tex]\displaystyle P(A)=\frac{7}{14}=\frac{1}{2}[/tex]
[tex]\displaystyle P(B)=\frac{3}{14}[/tex]
[tex]\displaystyle P(A\cap B)=\frac{1}{14}[/tex]
Therefore:
[tex]\displaystyle P(A\cup B)=\frac{1}{2}+\frac{3}{14}-\frac{1}{14}[/tex]
Adding the fractions:
[tex]\displaystyle P(A\cup B)=\frac{7+3-1}{14}=\frac{9}{14}[/tex]
The required probability is [tex]\mathbf{\frac{9}{14}}[/tex]
