If it snows ​tomorrow, the probability is 0.5 that John will practice his trumpet. If it does not snow ​tomorrow, there is only

a 0.4 chance that John will practice. Suppose the chance of snow tomorrow is 60​%. What is the probability that Justin will practice soccer this evening?

Answer:

The probability that Justin will practice soccer this evening is 16%.

Step-by-step explanation:

The probability that John will practice soccer is given by the product of the probability that it won't snow and the probability that he'll practice soccer. This is shown below:

practice soccer = (1 - 0.6)*0.4

practice soccer = 0.4*0.4

practice soccer = 0.16

The probability that Justin will practice soccer this evening is 16%,

Max invests some money in a savings bond.
Mars2501 [29]

Answer:

£5650

Step-by-step explanation:

The money max invested in the saving bond = x

After one year the intrest will be 2% of x

Amount = £5763

Amount = Principcal + Interest

= £5763 = x + 2% multiplied x

£5763 = x + 2x/100

= 50x/50 + x/50 = 5763

= 51x/50 = £5763

51x = 5763x50

51x = 288, 150

x = 288,150/51

x = 5650

So the money max invested = £5650

1. Determine a rule that could be used to explain how the volume of a
Eva8 [605]

Answer:

See explanation

Step-by-step explanation:

Solution:-

- We will use the basic formulas for calculating the volumes of two solid bodies.

- The volume of a cylinder ( V_l ) is represented by:

                                  V_c = \pi *r^2*h

- Similarly, the volume of cone ( V_c ) is represented by:

                                  V_c = \frac{1}{3}*\pi *r^2 * h

Where,

               r : The radius of cylinder / radius of circular base of the cone

               h : The height of the cylinder / cone

- We will investigate the correlation between the volume of each of the two bodies wit the radius ( r ). We will assume that the height of cylinder/cone as a constant.

- We will represent a proportionality of Volume ( V ) with respect to ( r ):

                                  V = C*r^2

Where,

            C: The constant of proportionality

- Hence the proportional relation is expressed as:

                                 V∝ r^2

- The volume ( V ) is proportional to the square of the radius. Now we will see the effect of multiplying the radius ( r ) with a positive number ( a ) on the volume of either of the two bodies:

                                V = C*(a*r)^2\\\\V = C*a^2*r^2

- Hence, we see a general rule frm above relation that multiplying the result by square of the multiple ( a^2 ) will give us the equivalent result as multiplying a multiple ( a ) with radius ( r ).

- Hence, the relations for each of the two bodies becomes:

                              V = (\frac{1}{3} \pi *r^2*h)*a^2

                                          &

                              V = ( \pi *r^2*h)*a^2

Find the volume of the object.
beks73 [17]

Answer:

896 inch^3

STAY SAFE, GOD BLESS YOU :)

Step-by-step explanation:

V = l x w x h

= 19 x 2 x 7

= 266 inch^3

= 6 x 15 x 7

= 630 inch^3

Add them both

= 630 + 266

= 896 inch^3
