Answer:
180
Step-by-step explanation:
180-120 = 60 this is one of all the congruent angles
of the top of my head i know a regular triangle has three 60 degree angles meaning it is 60*3 = 180
Answer: 54
Step-by-step explanation: I separated it into 3 areas in my head and then added up 21+21+12 to get 54
7 times 3 is 21
7 times 3 is 21
and
3 times 4 is 12
sorry if i am wrong i just did this in my head
Answer:
y=4/5x-2
Step-by-step explanation:
here are the given points: (5,2) and (10,6)
First, let's find the slope, which is found with the equation (y2-y1)/(x2-x1)
so let's label the points
x1=5
y1=2
x2=10
y2=6
now we can substitute into the equation
m=(6-2)/(10-5)
subtract
m=4/5
so that means the slope is 4/5
Now, let's use point slope form, which is y-y1=m(x-x1) (m is the slope)
so let's substitute the numbers we know from earlier into the equation
y-2=4/5(x-5)
do distributive prop.
y-2=4/5x-4
add 2 to both sides
y=4/5x-2
hope this helps!
Answer:
0.29
Step-by-step explanation:
Given :
n : ___ 0 _____ 1 ____ 2 ____ 3 ____ 4
P(n) : 0.82___ 0.11 ___0.04 _0.02 ___0.01
The expected number of defect in a shipment can be obtained using the expected value formula :
Expected value, E(X) = Σx*p(x)
Σx*p(x) = (0*0.82) + (1*0.11) + (2*0.04) + (3*0.02) + (4*0.01)
E(X) = 0.29
Hence, the expected number of defect in shipment is 0.29
