Your answer is most likely B
one ounce is too small
five pounds is too large
and four pounds seems like it wouldn't be accurate enough

Answer: b. 1 pound


Step-by-step explanation:

Given: Local hospital is making a histogram of the birth weight of babies born in the past year. there were 1023 babies born in the hospital last year. the weights range from 4 lb to 11 lb.

They should use 1 pound scale on the x-axis, which makes easier to to study the histogram. .

because from the given options 1 ounce is one sixteenth of a pound i.e. too small.

4 pounds scale will make total intervals =3 , which will make more difficult to study the histogram.

5 pounds scale is larger than 4 pounds scale, thus it can not be the rquired scale.

Find a quadratic polynomial the sum and product of whose zeroes are -8 and 12 respectively. Hence find the zeroes.
Olenka [21]

Step-by-step explanation:

We khow the sum and the product of the zeroes of this quadratic polynomial

Here is a trick :

when we khow the sum S and the product P ofvtwo numbers we can find them by solving :

x²-Sx+p=0

here S= -8 and P=12

so:

x²+8x+12=0

Let Δ be the discrminant of this equation: a= 1 , b= 8 and c=12

Δ= 8²-4*12 =16

the zeros are:

(-8-4)/2= -6

(-8+4)/2 = -2

verify:

-6+(-2)= -8

-2*(-6)= 12

now the polynomial quadratic is:

(x+6)(x+2)
