Answer:
Step-by-step explanation:
hello :
The expression 1/2mv^2
M=1.6x10^3
V=3.4x10^3
is : 1/2(1.6x10^3 )(3.4x10^3)²=2.72x 10^9
Answer:
a. 10 inches
b. 8 inches
c. 
Step-by-step explanation:
a. At side 0, perimeter is 0*4 = 0 in. At side 2.5 inches, perimeter = 2.5*4 = 10 inches, a change of 10 - 0 = 10 inches
b. At side 1, perimeter is 1*4 = 4 inches. At side 3 inches, perimeter = 3*4 = 12 inches, a change of 12 - 4 = 8 inches.
c. We can express the change in the square's perimeter P in terms of the change in the square's side length s as
Answer:
1600 dollars
Step-by-step explanation:
Find out how much you earn a month
1 month = 4 weeks
1 month = 100 x 4 = 400 dollars
Now find out 4 months
4 months = 400 x 4 = 1600 dollars
Answer: strong positive correlafion between data plan size 'x' and number of text messages sent 'y'
Step-by-step explanation:
'R' in statistics is used to denote correlation Coefficient. The correlation Coefficient is a value which ranges between -1 to +1. It tells us the level of relationship or correlation which exists between the relative movement of two variables, in this case the relationship between data plan size and the number of text messages sent in the US. R value of 0 depicts that no relationship exists between the two variables, R value closer the R value is to +1 and - 1 depicts the strength of positive and negative correlation of the two variables respectively.
A R value of +0.97 in the context above, depicts a strong positive correlation between data plan size and number of text messages sent in the US. That is large data size usually corresponds to large number of text messages and vice versa.
Since there is no graph presented, I will give an example. For instance you are given, 2n is greater than 30 and 5n is less than 100 and you are asked to find the value of n. This is an example of an inequality problem. You are given 2n is
greater than 30 and 5n is less than 100. You are asked to find for the value of
n. You need to know that greater means this sign ‘>’ and lesser means ‘<’
sign. So if you have 2n is greater than 30, this is equal to 2n>30 and 5n is
less than 100 is 5n<100. The ‘and’ means equal sign ‘=’. So,
2n>30+5n<100
2n-5n
