Given two points (x₁,y₁) and (x₂,y₂) the slope of the line passes through these points will be:
m=(y₂-y₁)/(x₂-x₁)
Data:
The points are (-4,7) and (-2,17), then the slope will be:
m=(17-7)/(-2+4)=7/2
Answer: the slope of the line passes through these points would be 7/2
Answer: A. Approximately 0.017 pounds
Step-by-step explanation:
Formula to find the margin of error :
, where z* = critical value for confidence interval , s= standard deviation , n= sample size.
As per given , we have
s= 0.15 pound
n= 300
Critical value for 95% confidence = 1.96
Then, Margin of error for 9%% confidence interval will be :
Hence, they can expect a margin error of 0.017 pound (approximately.)
Thus , the correct answer is A. Approximately 0.017 pounds
Answer:
If -1 4/5 wrong then I am sorry.
Step-by-step explanation:
Answer:
The required equation is:
0.23x = 52
Hence, option A is true.
Step-by-step explanation:
Given
Let 'x' be the initial depth
The snow is now 52 inches deep and it is a 77% decrease.
Let the initial 'x' depth be represented as 100%.
x → 100%
Given the current 52 inches is a 77% decrease. So, we need to decrease the 77/100 or 0.77 from the initial depth, so
[100% - 77%] of x = 52
[100/100 - 77/100] × x = 52
[1 - 0.77] × x = 52
0.23x = 52
Therefore, the required equation is:
0.23x = 52
Hence, option A is true.
-16t²-16t+96 = 0. use quadratic equation the roots are x= -3, and 2. 2 is the only answer that makes sense. So it takes 2 seconds
