andriy [413]

Answer:

(19/99) = 0.192

Step-by-step explanation:

Numbers 1 to 99, that is 99 numbers (obtained through the equation for the nth term of an AP)

L = a + (n-1) d

L = nth term = 99

a = first term = 1

n = number of terms = ?

d = common difference = 1

99 = 1 + (n-1)1

n = 99

Sample space = 99

The numbers that include at least, a 1 are

1, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 21, 31, 41, 51, 61, 71, 81, 91

19 numbers.

Probability of randomly selecting a card where the number contains at least one digit 1 from 1 to 99 = (19/99) = 0.192

Hope this Helps!!!

I learn maths and I don't know how to solve this problem.
Lyrx [107]

Answer:

As we get closer to x=-3, the limit is approaches -1, on both sides of -3 so this is a good limit so c is 8.

Step-by-step explanation:

In order for a limit to exists, the left side limit must exist and right side limit must exist and on top of that, they must be equal to each other.

In this case, this a piece wise function and by definition of a limit that exist, the limit of this piece wise function as x approaches 3 from either side, must be equal.

We let x=-3 for the top equation.

( - 3) {}^{2}  - 10 =  - 1

So we set the second equation equal to -1.

- ( {x}^{2} ) + c =  - 1

- ( - 3 {}^{2} ) + c =  - 1

- 9 + c =  - 1

c = 8

So the value of c is 8. We can prove this by graphing as well.

5(x+6)-2x=3(x+10) solve for x
Drupady [299]

Answer:

x=all real numbers

Step-by-step explanation:

1. distribute: 5(x+6)-2x=3(x+10)

                      5x+30-2x=3x+30

2. combine like terms 3x+30=3x=30

3. these are equal therefore x=all real numbers
