Answer:
First number =26
Second number =49
Step-by-step explanation:
Question:
The sum of two numbers is 75. The second number is 3 less than twice the first. Find the numbers.
Given:
Sum of two numbers = 75
The second number is 3 less than twice the first.
To find the numbers.
Solution:
Let the first number be = 
Let second number be = 
The sum equation can be given as:
It is given that the second number is 3 less than twice the first.
This can be given as:
Substituting the value of in terms of in the sum equation.
Combining like terms.
Adding 3 both sides.
Dividing both ides by 3.
Substitution in the second equation to find .
Thus, first number =26 and second number =49.
Answer: 28
Step-by-step explanation: round price to 70.00 then think 10% is $7....so 40% would be 7x4 = 28
Answer:
The graph of his initial step in the attached figure
Step-by-step explanation:
we have
This is a exponential function of the form
where
a is the initial value
b is the base
r is the rate of change
In this problem
a=3 ---> the initial value ( value of the function when the value of x is equal to zero)
b=4
b=1+r ----> 4=1+r ----> r=3 ---> r=300%
therefore
The initial value is the point (0,3)
The graph of his initial step in the attached figure
Answer:
The correct option is Histogram.
Step-by-step explanation:
In statistics, we usually come across a vast set of data. Data can be explained well when it is presented as a graph rather than as a table since the graphs have the capability to make known a trend or comparison.
Different types of graphs used in statistics to describe data are:
- Bar charts
- Pie charts
- Line charts
- Histogram
- Box Plot
- Dot Plot
And so on.
The methods commonly used for depicting a frequency distribution are:
- Histogram/Column graph
- Bar graph
- Frequency Polygon
- Pie chart
A histogram is used to graphically represent the distribution of a random variable according to the frequency distribution.
Each bar of the histogram is constructed according to a range of values and represents the frequency for that particular range.
In this case, we need to find how many pumpkins had masses below 6.0 kilograms.
The histogram can be used to construct the graphically representation of the masses of pumpkins and their frequency.
The range can be decided according to the provided masses.
Thus, the correct option is Histogram.
