Answer:
P = 0.23375
Step-by-step explanation:
given,
you remain in store for 15 minutes.
you friend remains in store for 10 minutes.
probability that they are store at the same time
from the graph attached below
shaded region shows the required probability,.
probability of the square = 1
probability of the shaded region = 1 - (area of lower triangle - area of upper triangle)
area of lower triangle = \dfrac{1}{2}(0.85)(0.85)
= 0.36125
area of the upper triangle = \dfrac{1}{2}(0.9)(0.9)
= 0.405
probability of the shaded region = 1 - (0.36125+0.405)
= 0.23375
Answer:
(D) an = 5n - 1
Step-by-step explanation:
The sequence is generated by substituting a value for n.
The first term of the sequence is 4
So when n = 1
The formula is an = 5n - 1
a1 = 5(1) - 1
a1 = 5 - 1
a1 = 4
The second term of the sequence is 9.
So n = 2
a2 = 5(2) - 1
a2 = 10 - 1
a2 = 9
To find the next value you just have to substitute the next value for n.

necesito puntos por eso estoy escribiendo esto
Step-by-step explanation:
To tell if JKON and JKLM are similar, compare the ratios between corresponding sides. For example:
JK / KO = 5/8
JK / KL = 5/22
The ratios aren't the same, so the shapes aren't similar.
Step-by-step explanation:
option 2 is the correct answer :)
