(c) 5p + 7 = 12 - 3p
8p = 5
p = 5/8 = 0.625
5. (a)
7p + 2 = 5p + 8
2p = 6
p = 3
(b) 7r + 2 = 5r - 20
2r = -22
r = -11
Answer:
x = 5
Step-by-step explanation:
Applying Pythagoras' identity to the right triangle
x² + 12² = 13²
x² + 144 = 169 ( subtract 144 from both sides )
x² = 25 ( take the square root of both sides )
x = 
= 5
Answer:
5
Step-by-step explanation:
p(2) - q(2)
3 - (-2)
3 + 2
= 5
Step-by-step explanation:
"The probability of drawing a red ace followed by another ace of any color without replacement."
There are 4 aces total, 2 of which are red. After the first red ace is drawn, there will be 3 aces left. So the probability is:
P = (2/52) (3/51)
P = 1/442
"The probability of drawing a king followed by a queen with replacement."
There are 4 kings and 4 queens. So the probability is:
P = (4/52) (4/52)
P = 1/169
"The probability of drawing a 3 or a 5 followed by a 4 or a 6 with replacement."
There are 8 cards that are either 3 or 5, and 8 cards that are either 4 or 6. So the probability is:
P = (8/52) (8/52)
P = 4/169
"The probability of drawing a spade followed by a jack of any color with replacement."
There are 13 spades, and 4 jacks. So the probability is:
P = (13/52) (4/52)
P = 1/52
Data is collected on the types of vehicles
this is cross sectional data
Time is not relavant for this data and hence cannot be time series data.
b)
from the given information, the variable is type of vehicle which is categorical data
c)
this data is only about the more frequent vehicles the chain cannot ignore the vehicles which are not parked
