Answer:

5

Step-by-step explanation:

The probability of tails is 1/2, so the expected value is (1/2) (10) = 5.

Answer:

5

Step-by-step explanation:

Probability of land a tail when the coin is tossed once is 1/2 because a coin has two sides and contains one head

Then when it is tossed 10 times, the no of time a tail appears is. 1/2 * 10 =5

How do u solve 4n-6=10n
Tcecarenko [31]

Answer:

n = -1

Step-by-step explanation:

4n - 6 = 10n

Combine like terms: (you can see that both 4n and 10n both have a n. This means that they are like terms. You would just add/subtract them as usual)

4n - 10n = 6

-6n = 6

n = -1

Triangle L M N is cut by line segment O P. Line segment O P goes from side M L to side M N. The length of O L is 14, the length
lions [1.4K]

Answer:

The value of y that would make O P parallel to L N = 36

Step-by-step explanation:

This is a question on similar triangles. Find attached the diagram obtained from the given information.

Given:

The length of O L = 14

the length of O M = 28

the length of M P = y

the length of P N = 18

Length MN = MP + PN = y + 18

Length ML = MO + OL = 28+14 = 42

For OP to be parallel to LN,

MO/ML = MP/PN

MO/ML = 28/42

MP/PN= y/(y+18)

28/42 = y/(y+18)

42y = 28(y+18)

42y = 28y + 18(28)

42y-28y = 504

14y = 504

y = 504/14 = 36

The value of y that would make O P parallel to L N = 36

The price of a new apple ipod has increased by 1/4. if the original price of the apple was $200, what is the price today? $150 $
marusya05 [52]
The price today is 250.

You first multiply 200 by .25 (which is the decimal form of 1/4). This will give you 50. After that, you add the 50 to the 200 to show the increase of 1/4.
