olasank [31]
7/8 = y/11

so multiply 11 to both sides of the equation

so now its (7*11)/8= y 

y=77/8

if decimal then 9.625

A - Frequency
Marina CMI [18]

Answer:

Step-by-step explanation:

When we collect a large data we may find a single entry repeated.  In these cases we prepare frequency distribution with x = the item in one column and f = the no of times it repeats i.e. frequency in other column.

Similarly for class intervals also, we write as frequency to the right side of interval column which gives no of items which fall within the class.

This process ensures compact presenting of data.

Hence we have

a)The number of observations that fall in a class

answer:   Frequency

b) The relative frequency of a class multiplied by 100

answer:   Percentage.  Because when we express probability as a percentage we get total 100

c) The ratio of the frequency of a class to the total number of observations

answer:  Relative frequency

(Relative frequency also known as probability is frequency/total entries)

olga2289 [7]

Answer:

The correct answer is D. AB ≅ WX

Step-by-step explanation:

No other choice involves a pair of congruent/similar lines. If the figure is rotated clockwise, you could transpose one over the other and AB would overlay WX exactly.

How do the prefixes in the metric system relate to the basic units?
WITCHER [35]
The basic unit of length in the metric system is the meter. Grams are used to measure weight and liter is used to measure liquid capacity
besides, it is used  so that you can express very large and very small numbers in a short unambiguous manner.
Example Instead of saying "three thousand million" meters
They classify the decimal place of the basic unit. ie, the meter is classified with milli (1/1000), centi(1/100), deci (1/10), Deca (10), Hecto (100), Kilo (1000).
