Answer:
The two distributions are each nearly symmetric.
Step-by-step explanation:
Symmetric distributions are those in which the data occurs in regular frequencies.
If we calculate the difference between the two standard deviations we find that it is only 0.022 which may be due to the physical or chemical properties of water or salt. So it lies within the same range and is almost symmetrical.
We cannot say that the distributions do not overlap on the same range of temperatures because they lie within the same range.
These two options are also incorrect as they are totally opposite of each other. Suppose the distribution of salt water boiling temperatures is left-skewed then the distribution of tap water boiling temperatures cannot be right-skewed as they have the same range and vice versa.
∠CEB and ∠AED are vertical angles, which means they must be equal to each other. Make them = x in an equation. The angles form a quadrilateral, so the sum of the interior angles must equal 360°.
77 + 77 + x + x = 360
Combine like terms.
154 + 2x = 360
Subtract 154 from both sides.
2x = 206
Divide both sides by 2.
x = 103
∠CEB is greater than 90°, so it must be an obtuse angle.
Answer:
- The function is a linear function.
- The function changes at a constant rate.
Step-by-step explanation:
The degree of x is 1, so the function is a linear function.
The coefficient of x is -90, a constant rate of change that is negative, so the function is <em>decreasing</em>.
To represent the opposite of this number, if it is positive nineteen,
he would need to first take nineteen steps back to reach his original
position which in this case represents zero. He would then need to take
another nineteen steps backwards, to reach negative nineteen.
