Why is it important for the leading coefficient to be nonzero?

Mathematics

kipiarov [429]3 years ago
4 0

Answer:

Because if it is zero, then it is multiplied the variable and it will be zero.  For example if I had 0x(squared) + x, it would just be x because zero times any number is zero.  Looking at the problem, I would assume it was quadratic because it had x squared, but it isn't because there are 0 x squared values.

Sum of the ages of A and B is 55 years. If the ratio of their ages is 6:5. find their ages...
lys-0071 [83]

Answer:

A's age = 6x = 6 × 5 = 30 years.

B's age = 5x = 5 × 5 = 25 years

Step-by-step explanation:

here's the solution : -

let their ages be 6x and 5x

and we know sum of their ages = 55

So, 6x + 5x = 55

=》11x = 55

=》x = 55 ÷ 11

=》x = 5

A's age = 6x = 6 × 5 = 30 years.

B's age = 5x = 5 × 5 = 25 years

maw [93]

Answer:

10.9361

Step-by-step explanation:

The lower control limit for xbar chart is

xdoublebar-A2(Rbar)

We are given that A2=0.308.

xdoublebar=sumxbar/k

Rbar=sumR/k

xbar      R

5.8        0.42

6.1         0.38

16.02    0.08

15.95    0.15

16.12     0.42

6.18      0.23

5.87     0.36

16.2      0.4

Xdoublebar=(5.8+6.1+16.02+15.95+16.12+6.18+5.87+16.2)/8

Xdoublebar=88.24/8

Xdoublebar=11.03

Rbar=(0.42+0.38+0.08+0.15+0.42+0.23+0.36+0.4)/8

Rbar=2.44/8

Rbar=0.305

The lower control limit for the x-bar chart is

LCL=xdoublebar-A2(Rbar)

LCL=11.03-0.308*0.305

LCL=11.03-0.0939

LCL=10.9361
