Answer:

We can say that is FALSE because the inhomogeneous sytem Ax =b can present an unique solution x = A^{-1}b if |A|\neq 0, so this is a good counter example on which we have a vctor that is not the trivial solution and we don't have an infinite number of solution.

Step-by-step explanation:

For this case we can use the following definition:

Let A x = b a linear system, this system is called homogeneous if b =0 and in other case is called inhomogeneous.

So then for the statement "The inhomogeneous system of equations Ax=b, where b\neq0, has either the trivial solution or an infinite number of the solutions."

We can say that is FALSE because the inhomogeneous sytem Ax =b can present an unique solution x = A^{-1}b if |A|\neq 0, so this is a good counter example on which we have a vctor that is not the trivial solution and we don't have an infinite number of solution.

How many times does the digit 7 appear among the terms of the sequence of consecutive integer numbers 7, 8, 9, ...., 777?
Dahasolnce [82]

Answer:

234 times

Step-by-step explanation:

<u>Number of times the number 7 appears in a hundred</u>

7 as units digit (07-17-27 ..... 97): 10 times

7 as tens digit (70-71-72..... 79): 10 times

20 times the digit 7 appears in first one hundred (0-100)

Let's calculate how many times 7 would be as units or tens in 7 hundreds

20X7 = 140 times digit 7 appears until number 699

<u>Now, from 700 to 777</u>

7 as hundreds digit (700-701-702 .... 777): 78 times

7 as tens digit (770-771-772 .... 777): 8 times

7 as units digit (707-717-727....777): 8 times

78 + 8 + 8 = 94 times the digit 7 appears in the range 700 - 777. Plus 140 times

140 + 94 = 234 times

Tim rolls a number cube labeled 1 through 6 and flips a coin. Which is the
ElenaW [278]

There are 3 numbers on the cube greater than 3 ( 4, 5, & 6)

This means he has a 3/6 = 1/2 chance of doing that.

He has a 1/2 chance of getting tails on the coin.

The probability of doing both would be the probability of the cube roll x the probability of the coin toss:

1/2 x 1/2= 1/4

The answer is 1/4

Another question yet again... HELP ASAP​
Rainbow [258]
V = l • w • h

Plug in the values:

90 = l • w • 6

Divide 6 on both sides:

15 = l • w

Break down 15 into factors:

5 • 3

Answer check:

5 • 3 • 6 = 90

The surface area of the shaded region is:

5 • 3 = 15

(I hope this is correct!)
