Answer: 12+2x
Step-by-step explanation:
Answer:
yes, we can reject the hypothesis
Step-by-step explanation:
The null hypothesis
H0 = mean weekly food budget for all households in this community is $98
Let´s find z
z= (x – mean) / standard deviation / √sample size
z = (100 – 98) / 10 / √100
z = 2
Using a Z table we can find probability
P (z>2) = 0.0228
Since P < α , results are significant and we can reject the hypothesis
10.) The lines that the angles are on are not parallel to each other. 11.) Angle 2 is also 60 degrees because they're corresponding angles. They're just on different lines but the place they meet the intersecting lines are the same. 12.) A real life situation that uses parallel lines are a rectangular room's walls that are parallel to each other.
Y = ax + 4x - 2 x= 1
y = a(1) + 4(1) -2
y = a + 2
y - 2 = a
