The answer would be the third choice as Geometry is essentially based on other proven theorems, axioms, and definitions.
Answer:
The first graph.
Step-by-step explanation:
When there is a negative discriminant, we call this "no solution" or "no real solution" because there are no x-intercepts. In the first graph, there are no x-intercepts.
Answer:
a) Response error
b) coverage error
c) coverage error
Step-by-step explanation:
Given situation:
(a) You want to know about the dating habits of college students, so you go to a dorm meeting and ask students how many dates they have had in the last year.
Solution:
In such situations the dating habits is a private matter for every individual and would not be truy expressed or conveyed in a dorm meeting. The true response would either be false or hidden in context of a public gathering.. So the likely error would be " Response error"
Given situation:
b) You want to know how often people attend religious services, so you stand outside a particular church on Sunday and ask entering individuals how often they attend.
Solution:
The collection of sample from a "particular" church limits the diversity of responses. The spread of the data might be skewed to certain geographical or population or ethnical locations. A better coverage would be recommended for accurate sampling. Hence, "coverage error"
Given situation:
(c) You want to know how often people eat at McDonald's, so you stand outside a particular McDonald's and ask entering customers how often they eat at McDonald's.
Solution:
The collection of sample from a "particular" McDonalds limits the diversity of responses. The spread of the data might be skewed to certain geographical or population or ethnical or lifestyles. A better coverage would be recommended for accurate sampling. Hence, "coverage error"
Answer:
The boy has 28 blue pencils
Step-by-step explanation:
Given
Total pencils = 40
The ratio of red to blue= 0.15:0.35
We have to find the number of blue pencils
For that we need the sum of ratio = 0.15+0.35 = 0.5
So, the number of blue pencils = (ratio of blue/sum of ratio) * total pencils
=0.35/0.5 * 40
=0.7*40
=28 pencils
Therefore, the boy has 28 blue pencils ..
