Step-by-step explanation:

There are four level of measurement for a data :

A) Nominal B) Ordinal C) Interval D) Ratio

In Nominal level , data is arranged in numerous categories.

Since, the favorite sports of respondents are identified as different categoirs such as 10 for basketball, 20 for baseball , 30 for football , and 40 for anything else.

Also, The average​ (mean) is calculated for 746 respondents and the result is 22.3 .

The best measure for the central tendency in Nominal level is MODE not mean.

So , to calculate the average is wrong with the given calculation.

What is x² + 7x - 30​
Aleonysh [2.5K]

Are you looking for the value of x?

We can complete the square/factor:

x^2+7x-30=0

(x+10)(x-3)=0

By the zero product property rule, we have two equations, x+10=0 and x-3=0.

So the zeroes of x are -10 and 3

Hope this helped. Comment below if this didn't make sense.

If sin θ = 2 over 7 and tan θ > 0, what is the value of cos θ?
sergey [27]
Sin θ = 2 / 7
tan θ > 0
cos θ = ?

sin θ = opposite / hypotenuse
tan θ = opposite / adjacent
cos θ = adjacent / hypotenuse

short leg = opposite = 2
hypotenuse = 7
long leg = adjacent = ?

adjacent = √(7² - 2²)
adjacent = √(49 - 4)
adjacent = √45
adjacent = √9 * 5
adjacent = 3 √5

cos θ = adjacent / hypotenuse
cos θ = 3√5 / 7
