What is the graph of 4x + 8y = 16?
1 answer:
Answer: Slope: -1/2 y-intercept: 2
Step-by-step explanation:
Subtract 4 x from both sides of the equation. 8 y = 16 − 4 x Divide each term by 8 and simplify. Divide each term in 8 y = 16 − 4 x by 8 . 8 y 8 = 16 8 + − 4 x 8 Cancel the common factor of 8 . Tap for fewer steps... Cancel the common factor. 8 y 8 = 16 8 + − 4 x 8 Divide y by 1 . y = 16 8 + − 4 x 8. y=2−x2. The slope-intercept form is y = m x + b , where m is the slope and b is the y-intercept. y = m x + b Reorder 2 and − x 2 . y = − x 2 + 2. Rewrite in slope-intercept form. y = − 1 2 x + 2.Slope:−1/2 y-intercept:2

Answer:
p value = 0.039
t = - 2.169
Step-by-step explanation:
Applying the null and alternate hypothesis
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
