140/15.5 = unit rate
140/15.5 = around 9.03
Average swimming rate: 9.03 meters per second
Answer:
X= 6
Step-by-step explanation:
Do the opposite instead of addition do subtraction to get x
25 minus 19
The correct answer is: No, the remainder is -114
Further explanation:
In order to check whether the given term is a factor of given polynomial or not we will put
x+2=0
x=-2
Given

As the remainder is -114, the term x+2 is not a factor of given polynomial
The correct answer is: No, the remainder is -114

Answer:
3.6669
Step-by-step explanation:
Given is a frequency distribution and we are expected to find the mean of the distribution.
Let X be the no of total pets owned and f be the number of adults owning those pets.
Total
x 1 2 3 4 5 6 7
F 248 567 1402 728 419 456 203 4023
x*f 248 1134 4206 2912 2095 2736 1421 14752
Mean 3.666915237
Thus we find the total of all frequencies and then sum of product of x*f.
Mean = sum of f*x/sum of x
Here mean= 3.6669
Solution :
It is given that P(x) is said to be complete or proper probability distribution if it satisfies the following two ways :
1. 
2. 
Now consider,

⇒ 
⇒ 
⇒ 
⇒ 
= 0.2
Therefore, the value of T is 0.2
Thus, option (c) is correct.
