A baseball player pays a flat admission fee of 10 dollars. The player has to pay 5 dollars per major league game, if the student has 35 dollars how much can they spend?

1. 10+5x <= 35

2. 5x<= 25

3. x<= 5

Make a number line

This means that the solution means they can participate in 5 major league games with 0 dollars left.

A lie-detector works correctly with 80% probability when the person is lying, and with 90% probability when the person is not. A

Answer:

the time percentage is 17%

Step-by-step explanation:

The computation of the time percenatge in the case when the detector lie and done with the mistake is as follows:

L denotes the event in which a person is lying.

NL denotes the event in which a person is not lying.

C denotes the event in which that lie detector works correctly

NC denotes the event in which lie detector is not working correctly

Now

P(C|L) =0.8

And,

P(NC|L) is

=1 - .8

= 0.2

P(C|NL) =0.9

P(NC|NL) is

= 1 -.9

=.1

P(L) = 0.7

P(NL) is

= 1 - .7

= .3

Now

P(NC) =P(NC|L) × P(L) + P(NC|NL) × P(NL)

=. 2 × .7 + .1 ×.3

=. 14+.03

= 0.17

Hence, the time percentage is 17%

A point M on a segment with endpoints X (1, −2) and Y (10, 3) partitions the segment in a 5:1 ratio. Find M. You must show all w

quester [9]

The point M is given by coordinates; (8.5, 2.16)

<h3>Ratio coordinate</h3>

The ratio XM : MY is 5:1

Therefore, on the x-axis;

The coordinate of M can be evaluated as follows;

5/1 = (a-1)/(10-a)

By Cross-product;

50 -5a = a -1

51 = 6a

a = 8.5.

Similarly, on the y-axis;

The coordinate of M can be evaluated as follows;

5/1 = (b-(-2))/(3-b)

By Cross-product;

15 -5b = b +2

13 = 6b

b = 2.16.

Ultimately, the coordinate of point M is; (8.5, 2.16)
