Answer: d) determinant cannot be found

<u>Step-by-step explanation:</u>

You can only find the determinant of a SQUARE matrix.

In other words, the dimensions must be 2 × 2 or  3 × 3 or ... n × n

The dimensions of the given matrix is 2 x 3, so the determinant cannot be calculated.

1)

\dfrac{3}{4}  + 5 -  \dfrac{1}{2}  = \dfrac{3}{4}  +  \dfrac{20}{4} -  \dfrac{2}{4}  =  \dfrac{21}{4}  = 5 \dfrac{1}{4}

2)

\dfrac{2}{3}  +  {2}^{3}  -  \dfrac{1}{3}  =  \dfrac{2}{3}  +  \dfrac{24}{3}  -  \dfrac{1}{3}  =  \dfrac{25}{3}  = 8 \dfrac{1}{3}

3)

- 15 + 6x - 19 - 20x =  - 14x - 34

4)

- 7x - 2 - 9y + 10x = 3x - 9y - 2

5)

14 + x = 18 \\ x = 18 - 14 \\ x = 4

6)

- 5x =  - 15 \\ x =  - 15 \div ( - 5) \\ x = 3

7)

- 2x + 8 = 18 \\  - 2x = 18 - 8 \\  - 2x = 10 \\ x = 10 \div ( - 2) \\ x =  - 5

8)

3x + 18 - 8x =  - 17 \\ 3x - 8x =  - 17 - 18 \\  - 5x =  - 35 \\ x =  - 35 \div ( - 5) \\ x = 7

As a​ follow-up to a report on gas​ consumption, a consumer group conducted a study of SUV owners to estimate the mean mileage f
kondor19780726 [428]

Answer:

The 95​% confidence interval estimate for the mean highway mileage for SUVs is (18.29mpg, 20.91mpg).

Step-by-step explanation:

Our sample size is 96.

The first step to solve this problem is finding our degrees of freedom, that is, the sample size subtracted by 1. So

df = 96-1 = 95

Then, we need to subtract one by the confidence level \alpha and divide by 2. So:

\frac{1-0.95}{2} = \frac{0.05}{2} = 0.025

Now, we need our answers from both steps above to find a value T in the t-distribution table. So, with 95 and 0.025 in the t-distribution table, we have T = 1.9855.

Now, we find the standard deviation of the sample. This is the division of the standard deviation by the square root of the sample size. So

s = \frac{5.6}{\sqrt{96}} = 0.57

Now, we multiply T and s

M = T*s = 1.9855*0.57 = 1.31

For the lower end of the interval, we subtract the mean by M. So 19.6 - 1.31 = 18.29

For the upper end of the interval, we add the mean to M. So 19.6 + 1.31 = 20.91

The 95​% confidence interval estimate for the mean highway mileage for SUVs is (18.29mpg, 20.91mpg).

Melissa runs a dog-boarding service. The cost to board a dog for one day is $25.00. If the same dog owner wants to board their d
myrzilka [38]

Answer: 25 + 15x ≤ 150

Step-by-step explanation: For this problem we will write an inequality to represent this situation.

Let x equal each additional day.

25 + 15x ≤ 150

The inequality above states that the dog owner will spend $25 for the first day and then for each additional day the dog owner will spend $15, but is budget is no more than $150 that the dog owner can spend.

3,857 rounded to the nearest thousand
alekssr [168]
3,857: 

1. 3 is located in the thousands place

2. Since 8 is bigger than 3, it's telling it to go up a number (turning 3 into a 4)

Stays the Same: 1,2,3,4
Goes Up: 5,6,7,8, etc.

So 3,857 is now rounded into 4,000
