Answer:10(6)
Step-by-step explanation: add them together? not 100% sure tho
Ok so 18x3=8x+128+10x (multiply the 8 with the stuff in the parenthesis) now you combine like terms so 54 = 128+18x now you have to get the numbers together so you subtract 128 ~> -74 = 18x then you divide -74/18 which is about -4.1 so x= -4.1
Answer:
y = -7
Step-by-step explanation:
This is a horizontal line
The y value does not change
It is of the form y=
y = -7
Answer:
ρ = 35% or 0.35
ρ with ^ =
or equivalently 46%
Step-by-step explanation:
ρ represents the population proportion of the bus riders, with a monthly pass, who are students.
The population proportion is simply the percentage of the entire population with a particular characteristic. We have been informed that in a city, 35% of the bus riders with a monthly pass are students. This means that 35% of the whole population of bus riders with a monthly pass are students. Therefore, our ρ is simply 35% or 0.35.
ρ with ^ represents the sample proportion of the bus riders, with a monthly pass, who are students. This is a statistic or an estimator as it is normally used to estimate the value of ρ, the population proportion. It is calculated using the formula;
ρ with ^ = 
where n represents the size of the sample and x the number of individuals in the sample with a certain desired characteristic. We have been informed that;
in a random sample of 50 bus riders with monthly passes, 23 are students.
Using the above formula and the values given we have;
ρ with ^ =
or equivalently 46%
