Answer:
D=A^-1
Step-by-step explanation:
Given that A is invertible and matrix D satisfies AD=I
Where I is an identity matrix
D is the inverse of A
Multiply both sides of AD=I by A^-1
A^-1(.AD) =A^-1 I
A^-1 .A=I
Therefore D=A^-1

Using the image of ⊙O to find the value of x, y and z.
Answer:
x = 30°
y = 60°
z = 96°
Step-by-step explanation:
Well the angle from the center that intercepts 120° is equal to 120° since it is a central angle.
y = 60° because oof supplementary angles.
The measure of z is 48 * 2 because the 48° is an inscribed angle.
z = 96°
And, the arc that angle y intercepts is also the arc the x intercepts.
That arc is 60° because 180° - 120° = 60°
x is an inscribed angle, so x = 1/2 * 60°
x = 30°

Which is true of the number 55,555?
A.Each digit has a value less than the value of the digit to its right and greater than the value of the digit to its left.
B.Each digit has a value 10 times the value of the digit to its right and 10 times the value of the digit to its left.
C.Each digit has a value 110 of the value of the digit to its right and 10 times the value of the digit to its left.
D.Each digit has a value 10 times the value of the digit to its right and 110 of the value of the digit to its left.
Answer:
D. Each digit has a value 10 times the value of the digit to its right and 1/10 of the value of the digit to its left
Step-by-step explanation:
Digits increase in value by a factor of 10 for each place you move to the left. Hence a digit to the right has 1/10 the value.
_____
Comment on place value
The multiplier for a base-10 (decimal) number system is 10 as you move one place to the left. In some other base, the multiplier is that base. In a binary (base-2) number system, each "bit" increases in value by a factor of 2 as you move to the left.
Therefore, the "Choice D" is the only correct answer.

The share of the pizza each friend will have is 1 / 6.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that three friends equally share 1/2 of a pizza. The fraction of the pizza shared by each friend will be:-
Fraction of pizza = ( 1 / 2 ) x ( 1 / 3 )
Fraction of pizza = ( 1 / 6 )
Therefore, the share of the pizza each friend will have is 1 / 6.

Robin is 11 years old. Her mother, Gwen, is 2 years more than 3 times Robin’s age. How old is Gwen?
Answer:
35 years old.
Step-by-step explanation:
To find the age of Gwen, multiply Robin's age, which is 11, by 3, which gives you 33. Then add two to 33 to get Gwen's age, which is 35 years.
Answer:
Gwen is 35 years old
Step-by-step explanation:
In order to understand the word problem better, I turned it into and equation.
Since Gwen is 2 years older than 3 times Robins age, the equation would be:
Gwens age = (3 • Robins age) + 2
G = (3 • 11) + 2
G = (33) + 2
G = 35
So Gwen is 35 years old.
A rectangular vegetable patch has an area of 56 square meters and a
perimeter of 30 meters. What are the dimensions of the vegetable patch?
meters by
meters
Answer:
The dimensions of the vegetable patch is 8 m by 7 m.
Step-by-step explanation:
Area of a vegetable patch is 56 square meters and the perimeter is 30 m.
If l is length and b is breadth, then area and perimeter of a rectangle is given by :
[tex]A=l\times b[/tex]
[tex]P=2(l+b)[/tex]
Substituting the values in the above formulas as :
[tex]l\times b=56\ ....(1)[/tex]
and
[tex]2(l+b)=30\\\\l+b=15\ .....(2)[/tex]
We need to solve equation (1) and (2) to find the values of l and b such that :
Equation (2), l = 15 - b
Equation (1) becomes,
[tex](15-b)b=56\\\\b=7\ m, 8\ m[/tex]
If b = 7 m, so, l = 8 m
If b = 8 m, l = 7 m
So, the dimensions of the vegetable patch is 8 m by 7 m.

Claim: Most adults would erase all of their personal information online if they could. A software firm survey of 564 randomly selected adults showed that 56% of them would erase all of their personal information online if they could. Find the value of the test statistic.
Answer:
The value of z test statistic is 2.871.
Step-by-step explanation:
We are given that a software firm survey of 564 randomly selected adults showed that 56% of them would erase all of their personal information online if they could. Find the value of the test statistic.
Let p = population proportion of adults who would erase all of their personal information online if they could.
So, Null Hypothesis, [tex]H_0[/tex] : p [tex]\leq[/tex] 50% {means that adults who would erase all of their personal information online if they could is less than or equal to 50%}
Alternate Hypothesis, [tex]H_A[/tex] : p > 50% {means that majority of adults would erase all of their personal information online if they could}
The test statistics that would be used here One-sample z test for proportions;
T.S. = [tex]\frac{\hat p-p}{\sqrt\frac{\hat p(1-\hat p)}{n} {} }[/tex] ~ N(0,1)
where, [tex]\hat p[/tex] = sample proportion of adults who would erase all of their personal information online if they could = 56%
n = sample of adults taken = 564
So, the test statistics = [tex]\frac{0.56-0.50}{\sqrt\frac{0.56(1-0.56)}{564} {} }[/tex]
= 2.871
The value of z test statistic is 2.871.

Chad is packing to go to college he packed 6 Mario games and nine brand new textbooks in a box the total weight of the box was 21 pounds realizing the box still had room and how strong he is, he put two more games in the box the new weight of the box is 22 pounds
What is the weight of one textbook and what is the weight of one game.
Answer:
0.5 pounds is one game
2 pounds is one textbook
Step-by-step explanation:
g = games
t = textbooks
Let's start with how much a game weighs. We know that when Chad added two more games the weight of the box increased by one pound (it was previously 21 pounds and then went to 22 when the two games were added). This means one game equals half of a pound (or 0.5 lbs.)...
[tex]2g = 1[/tex]
[tex]\frac{2g}{2} = \frac{1}{2}[/tex] -> if you divide one side by two, you must do the same to the other.
[tex]g = \frac{1}{2} = 0.5[/tex]
Now that we know the weight of the games, we can figure out the weight of the textbooks.
[tex]6g + 9t = 21[/tex] -> 6 games and 9 textbooks weigh 21 pounds.
Plugging in that each game is 0.5 pounds...
[tex]6(0.5) + 9t = 21[/tex]
[tex]3 + 9t = 21[/tex]
[tex]3 - 3 + 9t = 21 - 3[/tex]
[tex]9t = 18[/tex]
[tex]\frac{9t}{9} = \frac{18}{9}[/tex]
[tex]t = 2[/tex]
That means that each textbook equals 2 pounds.

Answer:
A
Step-by-step explanation:
Here you can check by trying points along the number line that are not included in the other number line. For example, x = -3 is included in A but not in B and x = -5 is included in B but not in A.
If x = -3, the inequality 5x > -20 is true because -15 > -20.
If x = -5, the inequality 5x > -20 is false because -25 is not > -20.
There for the answer should include x = -3 and not include x = -5, so A.

Arionna claims that since there are 3 feet in a yard, there are 9 cubic feet in a cubic yard. Which statement about her claim is
true?
Arionna is correct because there are 3 feet across the length of a cubic yard and 3 feet across the depth of a cubic yard.
3x3-9
Arionna is correct because there are 3 feet in a yard and there are 3 dimensions in a cubic yard length, depth, and height
3x3-9
Arionna is incorrect. There are only 3 cubic feet in a cubic yard because there are 3 feet in a yard, and the proportion wil
remain constant
Arionna is incorrect. There are 27 cubic feet in a cubic yard because a cubic yard is a prism with dimensions 3ft, 3x3ft
A prism with those dimensions will take 27 cubes to fill it if each cube is a unit cube of 1 ft
