Step-by-step explanation:
the rate of change in A
10-5/4.5-3 .5
=5.
but where is the function B??
just pick two y values and it's corresponding x values
the rate of change is equal to the gradient .
change in y values divided by change in the x values.
Answer is C
The conjugate of the complex number a+bi is a-bi
you just reverse the sign of the imaginary part of the number ; so it is 4-51i
Answer:
3000
Step-by-step explanation:
Convert them into numbers: 607 + 2393 = 3000.
The mean is also known as the average. For this problem, we want to find out the average distance that the guesses were from the true temperature. To do this, we need to add up all of the values and divide them by the number of values we have.
Person A:
-3 + -1 + 0 + 2 = -2
4 values
Person B:
4 + -4 + 2 + -3 = -1
4 values
Person C:
8 + -2 + 5 + 1 = 12
4 values
Totals:
-2 + -1 + 12 = 9
4 + 4 + 4 = 12 values
Find average:
9/12 = 0.75
The mean value in Fatima's results is 0.75.
Hope this helps!! :)
