If you multiply two matrices and obtain the identity matrix, it can be assumed the matrices are inverses of one another.
Explanation:
Answer:
False
Step-by-step explanation:
This is all I can think of.
Multiply two matrices and obtain the identity matrix, it can be assumed the matrices are inverses of one another. so, this statement is true.
Inverse of matrix is a matrix derived from another matrix such that if you multiply the two you get a unit matrix. Square matrices with a an inverse are called non singular matrices while those without an inverse are called singular matrices (determinant is zero). Inverses and determinant are only calculated for square matrices.
Two matrices are said to be inverse of each other.
If A B = B A = I, where I is the identity matrix.
So, the matrices are inverses of one another if the product of two square matrices is the identity matrix.

What sample size is necessary such that a 98% confidence interval for the mean, using σ = 3, has a width of pm±0.5?
Answer:
n = 195
Step-by-step explanation:
What sample size is necessary such that a 98% confidence interval for the mean, using σ = 3, has a width of pm±0.5?
We solve using Margin of error formula
= z × Standard deviation/√n
Margin of error = ± 0.5
Standard deviation = 3
n = ??
z = 2.326
Hence,
±0.5 = 2.326 × 3/√n
Cross Multiply
±0.5 × √n = 6.978
√n = 6.978/±0.5
√n = ±13.956
Square both sides
n = (±13.956)²
n = 194.769936
Approximately = 195 samples

josie walks 3/4 miles in 1/5 hour. what is josie’s speed in miles per hour
Answer:
3 miles per hour
Step-by-step explanation:
3 times 5 is 15 15 divided by 4 is 3
Josie's speed will be 15/4 miles per hour.
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Josie walks 3/4 miles in 1/5 hour.
Now,
The distance = 3/4 miles
The time = 1/5 hour
Since, We know that;
Speed = Distance / Time
Substitute all the values, we get;
Speed = 3/4 miles / 1/5 hour
= 3 x 5 / 4
= 15/4 miles per hour
Thus, Josie's speed will be 15/4 miles per hour.

Graph the lines in standard form 2x+y=9
Answer:
to graph this all you need to do is plot the y-intercerpt which is 9 in this case. then use the slop (-2) which means go two down from the y intercept and one to the right. all you need to do then is connect the points with a line.
9514 1404 393
Answer:
see attached
Step-by-step explanation:
A graphing calculator produces a graph very nicely.
__
Setting x=0, you have the equation y=9, so you know the y-intercept.
Setting y=0, you have the equation 2x=9, so you know the x-intercept is 9/2 = 4.5. It can be easier to set y=1 to find the corresponding point x=(9-1)/2 = 4.
Through the points (0, 9) and (4, 1), you can draw the line representing the relation.

A builder is designing a rectangular patio that has a length of 12 units. Find the total number of square units the patio will cover if the width is 4
Answer:
48 square units
Step-by-step explanation:
Use the area formula, A = lw, where l is the length and w is the width
Plug in the length and width:
A = lw
A = (12)(4)
A = 48
So, the patio will cover 48 units²
$600 7) Nika puts 42 beads in each necklace. Which is the best way to use rounding numbers to estimate the number of beads Nika needs for 2 necklaces? 25 x 45 O 30 x 30 O 20 x 40 O 30 x 40
Answer:
20 X 40 = 800 (split into 2 fourths) = 40
Step-by-step explanation
20 x 40 = 800;
For 2 necklaces she can split 800 into fourths.
800 - 40 = 80. (1 fourth)
80 - 40 = 40 (2 fourths)
40 - 40 = 0 (3 fourths)
She could split 800 into 2 fourths to get a number more than 0 and less then 42.
The best estimate of rounding 42 is 40. Because 40 is closer to 42.

Find the value of x

In the given triangle, the value of x is 12.
What is a triangle?A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.
The sum of the all three angles of a triangle is always 180°
In the given Triangle ABC,
AB= AC,
∠A = 34° and ∠C = (8x-23)°
Since, two sides of a triangle are equal, therefore their corresponding angle will be equal,
Implies that ∠C=∠B
The sum of all three angles of a triangle is 180°.
⇒∠A+∠B+∠C = 180°
⇒34+8x-23+8x-23 = 180
⇒16x-12=180
⇒16x=192
⇒x=12

In order, yes, yes, no, no.
Step-by-step explanation:
The two lesser side lengths should be equal or greater than the hypotenuse.
Answer:
A. False
B. False
C. False
D. False
Step-by-step explanation:
All of the answer choices can NOT be the side lengths of a triangle.
Using the Pythagorean theorem and its equation, we can determine that the sides lengths can't make a triangle. (Plug them into the equation accordingly to see why.)
For example, the second question says lengths of 5, 12, and 14. When plugged into the equation A^2 + B^2 = C^2, we see that the correct side lengths should be 5, 12, and 13.
