B) 9(a+b)+4 (3a+2b)=21a+17b
Answer:
So this problem is asking for the difference in the total amount of gas in the tank and the amount of gas consumed. You have the total amount of gas–15 gallons. You have the information in the problem to find the amount of gas consumed.
The car can go 32 miles before consuming a full gallon of gas and it traveled 384 miles. So if you divide the 384 miles by 32 miles per gallon, you are left with the gallons consumed.
Once you have this number, you can subtract it from 15 gallons–the total amount of gas in the tank–to get how much gas is left.

<h3>Defination of Quadrilateral Triangle :- </h3>
- A triangle is a simple closed curve or polygon which is created by three line-segments. On the other hand, in terms of Euclidean plane geometry, a polygon having four edges (or sides) together with four vertices is called a quadrilateral.
<h3>Examples of Quadrilateral Triangle :- </h3>
- A quadrilateral is a closed two-dimensional figure that has 4 sides, 4 angles, and 4 vertices.
- Examples of quadrilaterals are :- square, rectangle and trapezium.

It is proportional because all the points if put in fraction form equals 1/5. For 1 plant, he has 5 roses, and for 2 plants, he has 10 roses. 2/10=1/5. 3/15=1/5. 4/20=1/5. They all have the proportions of 1 plant per every 5 roses
Answer:
The data in statistics is generally supposed to deviate or vary from the mean. Standard deviations of 1, 2, and 3 are commonly used to calculate variability according to the empirical norm. In a normal distribution, we estimate 68 percent, 95 percent, and 98 percent of the data to be within 1, 2, and 3 standard deviations of the mean, respectively. This implies that the given percentage of data will lie within an interval of less than or greater than the standard deviation. If the values within a given standard deviation from the mean are standardized, the z value will always be equal to or less than the given standard deviation.
We should look at a program that aims to help people get out of poverty by using the standard deviation principle. The aim of the program is to provide free seeds to poor people who have been suffering from low yields due to the use of local seeds. If we use the definition of one standard deviation of the mean, or 2 and 3, we will favor the majority of people, but we will leave the poorest people in society behind.
