What is -5/8÷9/10=========
k0ka [10]

Answer:  -25 / 36

Solution:

Step 1: Lets flip the division sign to multiplication

Note : when the sign is reversed, the second term in the equation will have the numerator and denominator swapped  

-5/8 ÷9/10  > > > > > > -5/8 * 10/9

Step 2 : so it will be  

-5/4 * 5/9 when simplified,  which would be -25 / 36 > > > > >  - 0.69

Hope this solution will help you understand the problem and don't forget the negative sign it may cost you marks :)

inessss [21]

Answer:

ρ = 35% or 0.35

ρ with ^ = \frac{23}{50}=0.46 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 ^ = \frac{x}{n}

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 ^ = \frac{23}{50}=0.46 or equivalently 46%
