(25×4)6×5=130 and 8 need 20 characters so I need to type this
Step-by-step explanation:
angle G = 81°
angle CFG = 60°
total angle inside CFG = 180
a+81+60=180
a=39°
In DBCF
Total angle is 360
60+39+138+b=360
b=134°
hope its right :)
Answer:
0.1587
Step-by-step explanation:
Applying,
P(μ>40) = P(μ-(x-μ)/σ)............. Equation 1
Where P(μ>40) = probability of the age of the random subscriber more than 40 years μ = mean, σ = standard deviation, x = random subscriber
From the question,
Given: μ = 35 years, σ = 5 years, x = 40 years.
Therefore,
P(μ>40) = P(35-(40-35)/5) = P(35-(5/5)
P(μ>40) = 1-φ(1)
From the norminal probabilty table,
P(μ>40) = 1-0.8413
P(μ>40) = 0.1587
Answer: 4 + <u>8</u> < 22
Step-by-step explanation:
Take all of the given numbers from the set and add them with 4
4+8=12
4+18=22
4+26=30
<em />
<em>Meaning the only answer that is smaller than 22 is 4+</em><em>8</em>
<em />
Four plus eight is less than 22
Answer:
y= -1/2x+4
Step-by-step explanation:
slope = rise/run on the graph. the graph is going down, so it's negative. find where the line intersects the graph at a point and then count the squares up and over until it meets again. the line meets at (6,1), you count up one square and over 2 and it meets again. this gives you your rise/run = 1/2. the y intercept is where the line intersects the y axis. here the y intercept is 4 because the like goes through 4 at the y axis.
