HELP !!!! What are the solutions to the quadratic equation 6x^2 + 24x = 0 ( explain )

1 answer:

6 0

$6x(x + 4) = 0$
Now you have 2 case
$6x = 0$
and
$x + 4 = 0$
Solve
$6x = 0$
$x = 0$
Solve
$x + 4 = 0$
Minus 4 on both sides
$x = - 4$
The answers are x1=0 and x2=-4

Shalnov [3]

Answer:

p value = 0.039

t = - 2.169

Step-by-step explanation:

Applying the null and alternate hypothesis

$H_{0} : U1 = U2$

$H_{\alpha } : U1 \neq U2$

using excel worksheet to calculate for ( t and p )

t = -2.169

p = 0.039

from the results obtained

The conclusion is affected by the significance level because : 0.1 < p > 0.01

so when the significance level is = 0.1 the Null hypothesis is rejected and we can say the mean time interval will change while

if the significance level = 0.01 the Null hypothesis is accepted and we can not say the mean time interval has changed because the p -value is greater than 0.01
