Answer:
Yes, she can use a dotplot to describe her results.
Step-by-step explanation:
A dot-plot is a chart where each data is represented as a dot and it's values fall in discrete bins.
She can set a graph where 4 names of the product is represented on the horizontal axis and for each woman giving a name of the product, a dot is placed on top of the horizontal axis.
A sample dot-plot for this study is attached.
Answer:
18.18 miles.
Step-by-step explanation:
A truck uses 1 tablespoon of gasoline to drive 125 yards.
Now, 1 gallon of gasoline contains 256 tablespoons of gasoline.
So, the truck uses 1 gallon i.e. 256 tablespoons of gasoline to drive (256 × 125) = 32000 yards.
Now, 1-mile distance contains 1760 yards.
Therefore, the truck uses 1 gallon of gasoline to drive miles. (Answer)
Answer:
The error is at step (3) .
The correct step (3) will be,
= [by using the laws of indices]
All other steps are correct.
Step-by-step explanation:
The error is at the step (3) , because the student has tried to prove the quotient rule of logarithms by using the property i.e., 'The quotient rule of logarithm' itself , i.e. ,by assuming the property does hold before proving it. So, the proof is fallacious.
The correct step (3) will be,
= [by using the laws of indices]
All other steps are correct.
Answer:
x = 9
Step-by-step explanation:
Using the rule of exponents
×
⇔
Given
=
×
=
=
Since the bases on both sides are common, then equate the exponents
x = 9
