Option B

Probability of drawing yellow marble followed by a red marble is \frac{32}{301}

<em><u>Solution:</u></em>

Given that a bag containing 12 yellow marbles, 16 red marbles, and 15 green marbles

So total number of marbles = 12 + 16 + 15 = 43

To find: probability of drawing yellow marble followed by a red marble if the first marble is not replaced

<em><u>The probability of an event is given as:</u></em>

probability =\frac{\text { number of favorable outcomes }}{\text { total number of possible outcomes }}$

<em><u>probability of drawing yellow marble followed by a red marble if the first marble is not replaced:</u></em>

First we pick up yellow marble.

Number of favorable outcomes = 12 yellow marbles

Total number of possible outcomes = 43 marbles

\text{ probability} = \frac{12}{43}

Now we have to pick red marble

But first marble is not replaced

So we have 43 - 1 = 42 number of possible outcomes

Favorable outcomes = 16 red marbles

\text{ probability} = \frac{16}{42}

So probability of drawing yellow marble followed by a red marble is:

\text[ probability } = \frac{12}{43} \times \frac{16}{42} = \frac{32}{301}

Thus probability of drawing yellow marble followed by a red marble is \frac{32}{301}

Artyom0805 [142]

The speed while walking is 0.2 kilometers per minute

Step-by-step explanation:

The speed is calculated as distance per unit time.

Given

Distance = d = 5 km

Time by walking = t = 25 minutes

The speed is given by:

s = \frac{d}{t}

Putting the values

s = \frac{5}{25}\\s= 0.2\ km/min

The speed while walking is 0.2 kilometers per minute

Keywords: Speed, distance

Find the distance between the points (-10, -9) and (-7, -1).
QveST [7]

Answer:

Distance: 8.5440037453175

Step-by-step explanation:

Distance: 8.5440037453175

Steps:

Distance (d) = √(-7 - -10)2 + (-1 - -9)2

= √(3)2 + (8)2

= √73

= 8.5440037453175

Slope and Angle:

ΔX = -7 – -10 = 3

ΔY = -1 – -9 = 8

Slope (m) =  

ΔY

ΔX

=  

8

3

= 2.6666666666667

θ =  

arctan( ΔY )

ΔX

= 69.443954780417°

Equation of the line:

y = 2.6666666666667x + 17.666666666667

or

y =  

8 x

3

+  53

3

When x=0, y = 17.666666666667

When y=0, x = -6.625

Let’s solve for “a” and “s”.

a = 927 - 45s
a = 792 - 36s

927 - 45s = 792 - 36s
927 - 792 = 45s - 36s
135 = 9s
s = 15
a = 927 - (45 x 15) = 252
