Answer:
Solution given:
x. 
f. fx
13. 15. 195
14. 42 588
15. x. 15x
16. 10. 160
17. 3. 51
. n=70+x. 
=994+15x
we have
mean=sum/n
14.44=
14.44=
doing crisscrossed multiplication
(70+x)*14.44=994+15x
1010.8+14.44x=994+15x
15x-14.44x=1010.8-994
0.56x=16.8
x=16.8/0.56
x=30
Answer:
Your answer would be
B.) <u>f(x) = 3 cos (x) + 3</u>
I was able to graph it in desmos but it won`t let me attach an image.
Hope this helps!
Answer:
f(-3)= - (-3)+5= +3 +5 = 8
Answer:
The smaller number is 8
The bigger number is 11
Step-by-step explanation:
let the first number be A
let the second number be B
A + 2B = 30..... equation 1
A + B = 19...... equation 2
Subtract equation 2 from 1.
A + 2B = 30
- A + B = 19
-------------------
0 + B = 11
B = 11
Substitute B = 11 into equation 2
A + B = 19
A + 11 = 19
collect like terms
A = 19-11
A = 8.
A= 8 and B = 11
Answer:
Not a linear relationship
Step-by-step explanation:
Given
The attached table
Required
Linear or not
To do this, we simply calculate the slope of the table at different intervals.
Slope (m) is calculated as:
Let:
So, the slope is:
Let:
Let:
So, the slope is:
See that the calculated slopes are not equal.
Hence, it is not linear
