To find the slope,we can use the point-slope form:
Where m is the slope.
In this case,the equation would be:
-9-2 = m(1-(-3))
-11 = m(1+3)
-11 = 4m
m = -11/4
Therefore the slope is -11/4.
Hope it helps!
Answer:
- A cross-sectional study.
Step-by-step explanation:
A Cross-sectional study is demonstrated as the type of observational study in which the data or a representative subset of a population collected at a particular point in time is analyzed.
As per the given details, the observational study conducted by the research company would exemplify 'a cross-sectional study' as it aims to evaluate the data('viewing habits of about 50005000 households) collected at a specific point in time i.e. 'today' in order to 'determine the proportion of households tuning to a particular sports program.'
Set the shorter side of rectangle as X m
The longer side = (4X-6) m
58 = (X + 4X -6)2
58=10X -12
70 = 10X
X = 7
The shorter side is 7 m
And the longer side is 4 x 7 -6 = 22 m
Answer:
1) The smallest is 1000, and the greatest is 9998.
2) The smallest is 1001 and the greatest is 9999.
Step-by-step explanation:
Four digit numbers:
The set of four digit numbers is: {1000, 1001, ...., 9998, 9999}
Even numbers:
End in 0, 2, 4, 6, 8
Odd numbers:
End in 1, 3, 5, 7, 9
1) the number is an even number
The smallest is 1000, and the greatest is 9998.
2)the number is an odd number
The smallest is 1001 and the greatest is 9999.
Answer:
Ecological validity
Step-by-step explanation:
Well, to complete the sentence, first we need to be aware of types of validity of experiments such as criterion validity, ecological validity, content validity
, factorial validity, etc.
In this particular example, it is stated that the results of an experiment can be applied to real-world conditions. Therefore, the experiment is said to have ecological validity considering the fact that results applied to real-world conditions.
