Find the probability. Round to nearest tenth.

Answers

Answer:

Probability: (About) 0.8

Step-by-step explanation:

~ Provided that point X is randomly plotted on the line segment JM, we must calulculate the probability with which it lands on KM the first time ( implied ) ~

1. We know that the line segment JM, by the Partition Postulate ⇒ JK + KL + LM. With that being said JM = 3 + 7 + 4 = 14 units

2. Now line segment KM, by the Partition Postulate ⇒ KL + LM. With the assigned values, we can tell that KM = 7 + 4 = 11 units

3. If we were to determine the porbability that X lands on the line segment KM, considering the first try it would be KM/JM ⇒ Probability: 11/14

Solve 8m² + 20m = 12 for m by factoring


Please show all work

Answers

8m^(2)+20m=12 / :2
4m^(2)+10m=6
4m^(2)+10m-6 =0
\Delta=b^(2)-4ac
\Delta=100-(4*4*-6)
\Delta=100+96=196
x1=(-b-√(\Delta))/(8)
x1=(-10-14)/(8)
x1=(-24)/(8)
x1=-3
x1=(-b+√(\Delta))/(8)
x2=(-10+14)/(8)
x2=(1)/(2)

so you can write 8m^(2)+20m=12 / :2 as

8(m+3)(m-(1)/(2))=8*[m^(2)+2.5m-1.5]=0

a bowling ball is dropped from a height of 24 feet. write a function that gives the height h (in feet) of the bowling ball after t seconds

Answers

Answer:

h=16t^2

Step-by-step explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration due to gravity = 32 ft/s²

s=ut+(1)/(2)at^2\n\Rightarrow h=ut+(1)/(2)32* t^2\n\Rightarrow h=ut+16t^2

Here, u = 0 so,

h=0t+16t^2\n\Rightarrow h=16t^2

The equation is h=16t^2

24=16t^2\n\Rightarrow t=\sqrt{(24)/(16)}\n\Rightarrow t=1.22\ s

Time taken by the ball to hit the ground is 1.22 seconds
gravity pulls at 32 feet per second so it would take .75sec to hit the ground now make an equation that can make this applicable so after .75 second T it would be at 0 feet H

Find the missing term and the missing coefficient. 6a − ( )5a = ( )a2 − 35a

Answers

Answer:

The coefficient ( ) of 5a is filled by (41)/(5) and  the coefficient ( ) of a² is filled by ' 0 '

Step-by-step explanation:

The given expression is 6a - ( )5a = ( )a² - 35a

To find the missing coefficient, compare the left and right side of expression,

First compare the 6a - ( )5a = - 35a

6a+35a =  ( )5a

41a =  ( )5a

divide both the sides by 5a,

(41)/(5)=( )

(41)/(5)=( )

The coefficient ( ) of 5a is filled by (41)/(5)

Now, compare 0 =  ( )a²

So, the coefficient ( ) of a² is filled by ' 0 '

Hence, The coefficient ( ) of 5a is filled by (41)/(5) and  the coefficient ( ) of a² is filled by ' 0 '
(6a-7)5a=30a2-35a is the answer
