       f(x)  -  g(x)
=>  (3x²  +  x  - 3)  -  (x² - 5x + 1)
=>  3x² + x - 3 - x² + 5x - 1
=>  3x² - x² + x + 5x - 3 - 1
=>  2x² + 6x - 4

Easy peasy, since equals, just sub

f(x)-g(x)
(3x^2+x-3)-(x^2-5x+1)
distribute invisible -1
3x^2+x-3-x^2+5x-1
rearange terms or group like terms
3x^2-x^2+x+5x-3-1
add like terms
2x^2+6x-4


f(x)-g(x)=2x^2+6x-4

When an object falls freely, the formula for the distance it falls is d= 4.9t^2 where d is
german

Answer:

a) 122.5 m ; b) 10 s

Step-by-step explanation:

Just use the given equation and plug in what you know.

a)

d = 4.9t^2

d = 4.9(5^2)

d = 4.9 * 25

d = 122.5 m

b)

d = 4.9t^2

490 = 4.9t^2

100 = t^2

t = 10 s

Sheila bought some rose plants and sunflower plants.There were 35 rose plants than sunflower plants.If the ratio of the rose pla
DENIUS [597]
So assuming that youmeans there were 35 MORE rose plants than sunflower seeds, then

Rose:Sunflower =8:3

rose=sunflower+35
therefor

8 units=rose
3 units=sunflowers

rose-35=sunflower
8unit-35=3unit
5unit-35=0
5unit=35
therefor
35=5unit
divide by 5
7=1unit


so 8 units of roses

7 times 8=56

3 units of sunflowers
3 times 7=21

rose=56
sunflower=21

15. Which of the following statements is true? a. If the calculated value of F statistic is higher than the critical value, we r
quester [9]

Answer:

c) is true

Step-by-step explanation:

Given are four statements. Let us check one by one

a) If the calculated value of F statistic is higher than the critical value, we reject the alternative hypothesis in favor of the null hypothesis

False, we reject H0 in favour or alternate

b) The F statistic is always nonnegative as SSRr is never smaller than SSRur.

F statistics is non negative but reason is bot SSRr and SSRur are positive

Not because SSRr is never smaller than SSRur

c) Degrees of freedom of a restricted model is always less than the degrees of freedom of an unrestricted model.

This is true because in a restricted we put constraints thus df will be less

d) The F statistic is more flexible than the t statistic to test a hypothesis with a single restriction.

False.  F statistic is for testing variances while t statistic for means.
