Answer:
applying one way ANOVA:
R² = SSR / SST
= 0.133/1.807
=0.0734
Source of Variation SS df MS F P-value F0.05(2.27)
treatments 0.133 2 0.066 1.069 0.3574 3.354
error 1.675 27 0.062
Total 1.807 29
as p value is not significantly low:
Do the ANOVA results indicate that the null hypothesis (H0) can be rejected in favor of the alternative hypothesis (HA)? -No

Answer:
<h2>f(8) = 74</h2>
Step-by-step explanation:
f(x) = x² + 3x – 14
Then
f(8) = 8² + 3(8) – 14
= 64 + 24 - 14
= 64 + 10
= 74

Answer:
25 seconds
Step-by-step explanation:
Skydiving.
height (in feet) above the earth=h(t)= -16t^2 + 10,000
the time it would take to fall when h is 0
-16t^2 + 10,000=0
-16t^2=-10000
16t^2=10000
t^2=10000/16=625
t=sqrt 625=25 seconds
Answer: 3.8
Step-by-step explanation:first, you need to figure out what side you’re looking for. Side AC is opposite of the angle you’re given. They also give you length of side AB which is 4. That is the hypotenuse (side directly across from right angle). So, you have the hypotenuse, and need the find the opposite side measure. Which option uses opposite and hypotenuse? That’s Sin. So, you would do: sin70 = ? / 4.
sin (of given angle)= opposite / hypotenuse.
Sin (70 degrees) = ? / 4
Then you solve for “?”
Type sin70 into your calculator, then multiply both sides by 4 to get “?” by itself. You should get 3.758770483, which rounds to 3.8
