Find the probability. Round to nearest tenth.

Answers

Answer 1

Answer:

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

The total number of fungal spores can be found using an infinite geometric series where a1 = 8 and the common ratio is 4. Find the sum of this infinite series that will be the upper limit of the fungal spores.

Answers

The formula for infinite geometric series is equal to a1 / (1-r) where in this problem a1 is equal to 8 and r is equal to 4. In this case, r is not equal to less than 1. This means the sum should be infinity and cannot be determined definitely.

Answer:

This infinite geometric series is divergent and thus we cannot find the sum. The sum is infinity.

Step-by-step explanation:

There are two types of geometric series: convergent and divergent.

The sum of an infinite geometric sequence is given by the formula:

Sum = $(a)/(1-r)$

Where,

r is the common ratio and

$|r|<1$

If absolute value of r is NOT less than 1, then the series is divergent and sum cannot be found.

For our given problem, $r=4$ , clearly $|4|=4$ , which is NOT less than 1, so the series is divergent and sum cannot be found.

Find the equation of the line through the given point and perpendicular to the given line(0,0);-2x+4y=12

Answers

-2x+4y=12 <=> y = (-1/2)x + 3 => the slope of given line is -1/2;

the new line and the given line are perpendicular =>( the slope of new line )*(-1/2) = -1 =>

the slope of new line is 2;

the equation of the new line is y -0 =2( x -0) <=> y = 2x.

-2x+0 is perpendicular to -2x+4y=12, and go through (0,0).
So the answer is -2x+0

Rachel's penny bank is 3/10 full. After she adds 440 pennies, it is 4/5 full. How many pennies can Rachel's bank hold?

Answers

Let p = number of pennies we need to find.

(3/10)/(4/5) = p/440

Solve for p to find your answer.

Answer:

880

Step-by-step explanation:

Multiply the numerator and the denominator of 4/5 by 2 so it can be added. Rachel's bank would now be 8/10 full. If 440 pennies made it half full (8/10-3/10= 5/10, which equals 1/2) then 880 pennies (440 times 2) would fill it up completely. Hope this helps!

Distance between (0,2) and (0,4)

Answers

There are many ways to do this, I prefer the distance formula it looks like this:
$√((x_2-x_1)^2+(y_2-y_1)^2)$
We are given 2 pairs of coordinates: (0,2) and (0,4)
0=x1
2=y1
0=x2
4=y2
We take the numbers and sub in the values above in place of the variables:
$√((0-0)^2+(4-2)^2)$
Simplfy it:
$√((0)^2+(2)^2)$
0^2=0
2^2=4
We are left with :
$√(4)$
$√(4) =2$
Final answer: 2

D= √(x sub2 - x sub1)^2 + (y sub2 - ysub1)

D= √(0-0)^2 + (4-2)^2

D= √0^2 + 2^2

D= √0 + 4

D= √4

D = 2
