Answer:

\frac{1}{9}

Step-by-step explanation:

Given :A spinner has three equal sections labeled 1, 2, and 3. It is spun twice.

Solution :Which expression can be used to determine P(2, then 1)?

Solution :

Total no. of events = {1,2,3}=3

When it is spin for the first time .

Since we are given in the first spin she should get 2

No. of Favorable events ={2}=1

probability of getting 2 = \frac{\text{No. of favorable events}}{\text{No. of total events}}

= 1/3

In second spin she should get 1

No. of Favorable events ={1}=1

probability of getting 1= \frac{\text{No. of favorable events}}{\text{No. of total events}}

=\frac{1}{3}

Thus  P(2, then 1) = \frac{1}{3} *\frac{1}{3}

Hence the expression : P(2, then 1) = \frac{1}{3} *\frac{1}{3}

                                                         = \frac{1}{9}

A converging lens of focal length 5 cm is placed at a distance of 20
lesya [120]

The object should be placed 20/cm from the lens so as to form its real image on the screen

<h3>Mirror equation</h3>

The mirror equation is given according to the expression below;

1/f = 1/u + 1/v

where

f is the focal length

u is the object distance

v is the image distance

Given the following parameters

f = 5cm

v = 20cm

Required

object distance u

Substitute

1/5 = 1/u +1/20

1/u = 1/5-1/20
1/u = 3/20

u = 20/3 cm

Hence the object should be placed 20/cm from the lens so as to form its real image on the screen

Please i need help.....
Lina20 [59]

Answer:

A.105°

Step-by-step explanation:

Angle at W and V are equal and the angles at T and U are also equal

Hence taking angles at T and U...so as to calculate the value of x

5x + 15 = 3x + 21

5x - 3x = 21 - 15

2x = 6.....hence, x = 3

Then for the angle of VXU;

All angles in a triangle add up to 180°

15(3) + 3(3) + 21 = 75°...then subtract from 180°..so as to obtain angle at VXU

180 - 75 = 105°
