Answer:
The two numbers are 13 and 6.
Step-by-step explanation:
x+y=19
x-y=7
-----------
2x=26
x=26/2
x=13
13+y=19
y=19-13
y=6
x=13, y=6.
Answer:
32 kgs ?
Step-by-step explanation:
Observation that we can make is min = 10, max = 19, range = 9, Maximum frequency of a number is 12, Average = 12.9, median = 12, mode = 12 it is slightly skewed on the right.
Step-by-step explanation:
- It is imperative to create a data in a tabular column before analyzing.
- Once the data is created use tally marks or frequency distribution.
- Frequency distribution helps the data to provide occurrence of event.
- Very important to number which is a counting numbers are discrete.
- Continuous of data are ones which are in decimal.
- Descriptive statistics is the 1st level of Statistics.
- It finds, where the data stands. Minimum, Maximum is understandable.
- Range is at what level data is expanded.
- Average is the one numeric of a number.
- Median is the mid point of data
- Mode is the repetitive number of the data.
- Skewness is whether data is having extreme directions.
The answer is x=42.8+- (plus or minus) 12
So he should either have $30.80 or $44.80 left
Answer:
![f (x) = x (x + 5) (x-9)](https://tex.z-dn.net/?f=f%20%28x%29%20%3D%20x%20%28x%20%2B%205%29%20%28x-9%29)
Step-by-step explanation:
The zeros of the polynomial are all the values of x for which the function ![f (x) = 0](https://tex.z-dn.net/?f=f%20%28x%29%20%3D%200)
In this case we know that the zeros are:
![x = 9,\ x-9 =0](https://tex.z-dn.net/?f=x%20%3D%209%2C%5C%20%20x-9%20%3D0)
![x = 0](https://tex.z-dn.net/?f=x%20%3D%200)
, ![x + 5 = 0](https://tex.z-dn.net/?f=x%20%2B%205%20%3D%200)
Now we can write the polynomial as a product of its factors
![f (x) = x (x + 5) (x-9)](https://tex.z-dn.net/?f=f%20%28x%29%20%3D%20x%20%28x%20%2B%205%29%20%28x-9%29)
Note that the polynomial is of degree 3 because the greatest exponent of the variable x that results from multiplying the factors of f (x) is 3
