-5x^5 * -8x^4 - 5x^5*-9x - 5x^5*-9
= 40x^9 + 45x^6 + 45x^5
The square root of 16=4, 4x2=8, x2=8.
Answer:
The correlation between hour of the day and the speed over the limit at which the motorist is ticketed is weak positive correlation.
Step-by-step explanation:
The correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.
The types of correlation coefficient are:
- +1 (-1) : Perfect positive (negative) correlation
- 0 to 0.30(-0.30) : Weak positive (negative) correlation
- 0.30(-0.30) to 0.70(-0.70) : Moderate positive (negative) correlation
- 0.70(-0.70) to 1 (-1) : Strong positive (negative) correlation
The correlation coefficient value between the hour of the day and the speed over the limit at which the motorist is ticketed is:
<em>r</em> = 0.12.
The value of <em>r</em> lies between:
0 < 0.12 < 0.30
Thus, the correlation between hour of the day and the speed over the limit at which the motorist is ticketed is weak positive correlation.
We want to increase by 15% so we want 100% plus 15% which means 115%
Since we want 115% lets make the calc:
65 pizzas ----------- 100%
x pizzas ------------- 115%
Multiply in cross
65 . 115 = 100.x
7475 = 100.x
x = 74,75
Since we cant sell 74 pizzas and 0,75 pizza we will sell 75 pizzas
So we need to sell 75 pizzas to employees receive the bonus
Answer:
C
Step-by-step explanation:
This is a geometric sequence with n th term
= a 
Where a is the first term and r is the common ratio
r = 
= 
= 
= 
, hence
f(n) = 16 
→ C
