The number 1934 can be written as:
1,000 + 900 +30 +4
so the value of the 3 is 30, of the 9 is 900 and of the 1 is 1000.
900 is indeed 10 times 30, so
"<span>the value of the 9 in the hundreds place ten times the value of the 3 in the tens place</span>"
Answer: true
Answer:
t=100-2x
Step-by-step explanation:
Answer:
27
Step-by-step explanation:
Replace the x in f(x) by g(x) to get (f o g)(x)
= 2(4x - 3) - 7
= 8x - 6 - 7
= 8x - 13
so (f o g) (5)
= 8(5) - 13
= 27
Answer:
Option 5) 23.5% is a parameter and 28% is a statistic
Step-by-step explanation:
We are given the following in the question:
"According to the U.S. Census bureau, 23.5% of people in the United States are under the age of 18. In a random sample of 250 residents of a small town in Ohio, 28% of the sample was under 18."
- Population is the collection of all the observation of individual of interest.
Population of interest:
People in the United States
- Parameter is any value that describes the population.
Parameter:
23.5% of people in the United States are under the age of 18
- Sample is a subset of a population and is always smaller than the population.
Sample:
Random sample of 250 residents of a small town in Ohio
- Statistic is any value that describes a sample.
Statistic:
28% of the sample was under 18
Thus, the correct answer is
Option 5) 23.5% is a parameter and 28% is a statistic
Area of the trapezoid can be calculated as:
Area = 0.5 x Height x Sum of Length of Bases
We have the measure of area and length of bases. Using the above formula we can find the height h of the trapezoid.
So, using the values we get:
Thus, the height of the trapezoid will be 6 in.
