Answer:
A p-value if 0.047(same as 4.7%) means there is a 4.7% chance that there is no difference in how effective the new treatment is.
Step-by-step explanation:
When we talk of a p-value, we are referring to a conditional probability. What it tells us is the probability of getting results which are at least as unusual as the observed statistics in a case where we are given that the null hypothesis is not false.
A p-value if 0.047(same as 4.7%) means there is a 4.7% chance that there is no difference in how effective the new treatment is.
So what this means is that, in this case it is better that more data is collected to enable us know how effective the new treatment is
Answer:
y = 658.3 ft
Step-by-step explanation:
Angle of depression = angle of elevation = 28° (alternate angles are congruent)
Reference angle = 28°
Side length opposite to reference angle = 350 ft
Adjacent = y
Apply trigonometric function, TOA:
Tan 28 = Opp/Adj
Tan 28 = 350/y
y*Tan 28 = 350
y = 350/Tan 28
y = 658.254263 ≈ 658.3 ft (nearest tenth)
Answer:
Area of shaded region ≈ 192.42
Step-by-step explanation:
21/2 = radius
radius = 10.5 m
A = πr squared
Area of shaded region≈346.36
10.5 - 3.5 = 7
Area of unshaded region ≈ 153.94
346.36 - 153.94 = 192.42
X+5 ≤ -17
Or if it’s y instead of x put that.
Hope this helps though
Based on the fact that you are allowed to multiply as many 2's and/ or as many 5's as you want, the last digit of your result can be either a 2, 5 or 0.
<h3>What is the last digit of your result?</h3>
If you multiplied a 5 number with another 5 number, you will either get a 0 as the last digit or a 5 as the last digit:
5 x 5 = 25
5 x 10 = 50
5 x 15 = 75
5 x 25 = 125
If you multiply a 5 with a 2, you result would always end in 0:
5 x 2 = 10
5 x 4 = 20
5 x 6 = 30
If you multiply a 2 with another 2, the result would be a 2:
2 x 2 = 4
2 x 4 = 8
2 x 6 = 12
