Answer:  The required probability is 0.1%.

Step-by-step explanation:  Given that we have decided to play a Pick 3 lottery game in which we have to guess the exact order of the three numbers.

We are to find the probability of winning.

Let S denotes the sample space for choosing 3 numbers out of 10, .i.e., from 0 to 9. And A denote the event that we chose the exact order of the three numbers.

Since a number can be chosen more than once, so

n(S)=10\times10\times10=1000,\\\\n(A)=1.

Therefore, the probability of event A will be

P(A)=\dfrac{n(A)}{n(S)}=\dfrac{1}{1000}=\dfrac{1}{10}\%=0.1\%.

Thus, the required probability is 0.1%.

The best and most correct answer among the choices provided by the question is the second choice "a right angle"The formula for finding the slope of a line on a coordinate plane is (y2 - y1) / (x2 - x1), where (x2, y2) and (x1, y1) represent two distinct points on the line. This is also known as "change in y over change in x" or "rise over run."I hope my answer has come to your help. God bless and have a nice day ahead!

The mean age of 9 women in an office is 27 years old.
Veronika [31]

26 to nearest year

We require the total of the sums of ages for both groups before calculating the mean for all 16

using mean = \frac{sum}{count}

Women

27 = \frac{sum }{9} ( cross- multiply )

sum = 9 × 27 = 243

Men

25 = \frac{sum}{7} ( cross- multiply )

sum = 7 × 25 = 175

Total sum of all 16 = 243 + 175 = 418

mean = \frac{418}{16} = 26 ( to nearest year )

Leslie ran 3 mile race. The second mile took her 10 percent longer than the first one and the third mile took her 24 seconds lon
Brilliant_brown [7]

Answer:

8.8 Minutes or 528 Second.

Step-by-step explanation:

↓[ Read Below ]↓

Important Info:

Leslie Ran 3 Mile Race.

2nd Mile = 10% longer than 1st and 3rd Miles took her 24s longer than 2nd Mile

Question to Answer:

Leslie’s total time for the race was 26 minutes how long did the second mile take her?

Explanation/Solution:

Let for first mile, she took x minutes . And second mile took her 10 percent longer, so second mile took

x+ 10/100x = 110/100x=1.1x

And the third mile took 24 seconds longer as compared to second mile .

So third mile took

1.1x+24/60 = (1.1x+0.4) Minutes

And the total time for the race was 26 minutes, that is

x+1.1x+1.1x+0.4=26

3.2x=26-0.4

3.2x=25.6

x= 25.6/3.2 = 8 Minutes

So the first mile took 8 minutes. And therefore second mile took

= 1.1 (8) = 8.8 Minutes

Also Equal to 528 Second.
