Answer 1

Answer:

Answer:

$\large\boxed{x>-25}$

Step-by-step explanation:

$-(3)/(10)x-7<(1)/(2)\qquad\text{multiply both sides by 10}\n\n10\!\!\!\!\!\diagup^1\cdot\left(-(3)/(10\!\!\!\!\!\diagup_1)x\right)-(10)(7)<10\!\!\!\!\!\diagup^5\cdot(1)/(2\!\!\!\!\diagup_1)\n\n-3x-70<5\qquad\text{add 70 to both sides}\n\n-3x<75\qquad\text{change the signs}\n\n3x>-75\qquad\text{divide both sides by 3}\n\nx>-25$

Explain why P(A|D) and P(D|A) from the table below are not equal.

Answers

Answer:

The two conditional probabilities are not equal because each has different given events. P(A|D) has event D as its given event, resulting in 2/10 for a probability. P(D|A) has event A as its given event, resulting in 2/8 for a probability.

Other part is:

different given events

P(A|D) equals 2/10

P(D|A) equals 2/8

because they are in different positions which make them different answers/number

Describe two different methods to find the elapsed time from 2:30pm to 2:58pm

Answers

Answer:

We know that:

" Elapsed time is the time or difference between a beginning time and an ending time ".

Now the two different methods to find the elapsed time is:

Method 1:

Subtract 2:30 directly from 2:58.

2:58 - 2:30 = 0:28

Hence, the elapsed time is 28 minutes.

Method 2:

Round 2:58 to 3:00, subtract 2:30 from 3:00, and at the end subtract 2 to get the desired time(2:58 + 2 = 3:00)

( Since it is easy to calculate the whole numbers).

2:58 is approximately 3:00

3:00 - 2:30 = 30 min

30 min - 2 min = 28 min.

Hence, elapsed times is 28 minutes.

You could substract or you can count up till you get to 2:58pm from 2:30pm

Simone painted a line around the entire perimeter of her rectangular tennis court. The length of the court was 78 feet and the width was 27 feet. How long was the line Simone painted? A. 54 feet B. 105 feet C. 183 feet D. 210 feet

Answers

It would be D. 210 feet.

P = 2L + 2W
P = 2(78) + 2(27)
P = 156 + 54
P = 210 ft
