Parallel lines have the same gradient so it’s the second or the fourth answer.
y = mx + c
y = 2x + c
3 = (2 x 2) + c
3 = 4 + c
3 - 4 = c
c = -1
y = 2x - 1
Answer:
1/5 or A
Step-by-step explanation:
Hello. Please excuse the idiot above we do not know how he formed or why he speaks like a gorilla on crack. Anyways, we, humans, believe that 1/5 is the correct answer since their are 5 intervals between 0 and 1 between one of the tick marks is 1/5 since there are 5 intervals. I really hope you guys are human not this gorilla above us. I hope I made your day please rate 5 stars , add thanks and please mark brainliest. :)
Answer:
ok so the sale ticket cost 54 so we want to find what the regurler one cost so lets just make a algreva equation
0.9x=54
divide by 0.9
54 divide by 0.9=60
so a regurer ticket cost 60
54=0.9r
Hope This Helps!!!
To solve this problem, what we have to do is to calculate
for the z scores of each condition then find the probability using the standard
normal probability tables for z.
The formula for z score is:
z = (x – u) / s
where,
x = sample value
u = sample mean = 23 days
s = standard deviation = 1 day
A. P when x < 21 days
z = (21 – 23) / 1
z = -2
Using the table,
P = 0.0228
Therefore there is a 2.28% probability that the hatching
period is less than 21 days.
B. P when 23 ≥ x ≥ 22
<span>z (x=22) = (22 – 23) / 1 = -1</span>
P (z=-1) = 0.1587
z (x=23) = (23 – 23) / 1 = 0
P (z=0) = 0.5
P = 0.5 - 0.1587 = 0.3413
Therefore there is a 34.13% probability that the hatching
period is between 22 and 23 days.
C. P when x > 25
z = (25 – 23) / 1
z = 2
P = 0.9772
This is not yet the answer since this probability refers
to the left of z. Therefore the correct probability is:
P true = 1 – 0.9772
P true = 0.0228
<span>Therefore there is a 2.28% probability that the hatching
period is more than 25 days.</span>
Answer:
3/20 cake in 1 minute
Step-by-step explanation:
"3/4 of a cake in 5 minutes" is a verbal equation. We can divide both sides (that is, 3/4, 5 min) by 5 to determine the number of cakes I can bake in 1 minute:
3 5 min
-------- cake in -----------
4(5) 5
resulting in 3/20 cake in 1 minute.
