Answer:
A) 92
Step-by-step explanation:
A full revolution is shown which means it should add up to 360.
To find b, subtract 227 and 41 from 360:
360 = 227 + 41 + b
b = 92
ANSWER: 1 SOLUTION
Step 1: Subtract 2x-1 from both sides.
x2−(2x−1)=2x−1−(2x−1)
x2−2x+1=0
Step 2: Factor left side of equation.
(x−1)(x−1)=0
Step 3: Set factors equal to 0.
x−1=0 or x−1=0
x=1
Answer:
x=1
For the first one the answer is y=-1x+6 which means x=-1 and y=6
Answer:
Matching the vocabulary word with its corresponding example:
1. All children who Ski and Snowboard = population (a group of items, units or subjects which is under reference of study e.g inhabitants of a region, numbers of cars in a city e.t.c)
2. The 92 children who were asked when they took their first lesson = Sample (a part or fraction of a population selected on some basis)
3. The average age that all children take their first to lesson = Parameter (the number that summarizes some characteristics of a population
4. The average age that the 92 children took their first lesson = statistic (a sample characteristic corresponding to the population parameter used when a sample is use to make inference about a population)
5. The age that children take their first listen = variable (anything that has attribute, quality or quantity that varies or a characteristic/attribute that describes a place, person or thing)
6. The list of the 92 ages that the children from the study took the first listen = data (facts that are collected together for analysis)
