Answer:
Ordered pair of yz is ( 9 , 9 ) and Magnitude of yz is 9√2 unit.
Step-by-step explanation:
Given ordered pair of y and z are ( 14 , -23 ) and ( 23 , -14 ) respectively
To find: Ordered pair of yz and magnitude of yz
To find order pair of yz we subtract ordered pair of y from z.
Ordered pair of yz = ( 23 - 14 , -14 - (-23) )
= ( 9 , -14 + 23 )
= ( 9 , 9 )
Magnitude of yz ,
=
=
=
Therefore, Ordered pair of yz is ( 9 , 9 ) and Magnitude of yz is 9√2 unit.
Answer:
A
Step-by-step explanation:
Morning Rate = 3 pints/4 minutes
Afternoon Rate = 2 pints/3 minutes
Lets find the rate in pints per hour for each. (Remember, 60 minutes in an hour). Let x be number of pints
Morning Rate =
Afternoon Rate =
Morning Rate = 45 pints/hr
Afternoon Rate = 40 pints/hr
The difference is 5 pints/hr
Correct answer A
Complete Question:
The scatter plot shows the number of oranges picked, in hundreds, in relation to the number of lemons harvested, in hundreds, by several farmers.
According to the plot, which value is the best estimate of the correlation coefficient of the data?
A. -0.2 B. -0.9 C. 0.9 D. 0.2
*See attachment for the scatter plot.
Answer:
C. 0.9
Step-by-step explanation:
The scatter plot given in the graph attached shows a relation between oranges picked and the number of lemon that is harvested as the line slopes in an upward direction. This suggest a positive correlation coefficient, because as the variable on the Y-axis increases, the variable on the X-axis also increases in the same direction. Hence, our correlation coefficient would be a positive value.
Also, the correlation coefficient would be close to 1, because the points on the scatter plot seem clustered and aligned along the line slope.
Therefore, the best estimated value for the correlation coefficient would be C. 0.9.
Answer:
39
Step-by-step explanation:
square= lw
triangle= 1/2lw
s=9
triangle=15 divided by 2 times 4=30
you add 30 + 9 which will give you 39
