Answer:
perimeter: add p + m + n
area: use (p × m)/2
find missing side: use p^2 + m^2 = n^2
The x-intercept is the x-coordinate of a point where a graph intersects the x-axis and the y-intercept is the y-coordinate of a point where a graph intersects the y-axis. For example, (-4,0) -4 is the x-intercept and (0,6) 6 is the y-intercept
Answer:
2 < x < 5
Step-by-step explanation:
<u>< This symbol means 'less than'</u>. The number you put on its left side is less than the number on its right side.
<u>> This symbol means 'greater than'</u>. The number put on its left is greater than its number on the right.
Think of them like a mouth. Remember the 'open side' wants to eat more.
Translate words to symbols:
'x is less than 5'
x < 5
'x is greater than 2'
x > 2
Put them together. The < and > symbols change directions, but x on the closed side of 5. Keep x on the open side of 2.
2 < x < 5
Don't confuse < and > with ≤ and ≥.
≤ and ≥ mean 'less than OR equal to' and greater than OR equation to'.
Answer:
The answers to the questions are
(a) P = 0.0176
(b) P = 0.5
(c) P = 0.0571
Step-by-step explanation:
The P value is the calculated probability of obtaining extreme reults which are as extreme as observed res ult when the study null hypothesis H₀ is true
The p value is given by
P (
= 185 when μ = 175)
z = 
z(
= 185) = 
= 1.5811
Therefore the P ( = 185 when μ = 175) = P(z = 1.5811)
0.94295
The probability density function is
Therefore the probability is
= 0.0176
b) The type II error is given by
β = P(type II error) = P(Fail to reject the null hypothesis when it is false)
Therefore
β = P ( < 185 when μ = 185)
P
, which gives
P(z<0) and β = 0.5
(c) For true mean foam height of 195 mm we have
β = P ( < 185 when μ = 195)
and P
Which gives P(z < -1.58)
From z table the probability is β = 0.0571
