Answer:
=10
=-7
=2.2
=60
Step-by-step explanation:
2x-6=14
2x=20
x=10
-5x+5= 40
-5x = 35
x= -7
10x + 2 = 24
10x = 22
x= 2.2
1/6x +1 = 11
1/6 x = 10
x = 60

Answer:
C. Events E and A are independent
Step-by-step explanation:
we will verify each options
(a)
We can use independent events formula
P(B∩C)=P(B)*P(C)
we are given
P(B)=0.4
P(C)=0.25
P(B∩C)=0.05
now, we can plug these values into formula
and we get
0.05=0.4*0.25
0.05=0.1
we can see that left side is not equal to right side
so, this is FALSE
(b)
We can use independent events formula
P(D∩A)=P(D)*P(A)
we are given
P(D)=0.25
P(A)=0.6
P(D∩A)=0.1
now, we can plug these values into formula
and we get
0.1=0.25*0.6
0.1=0.15
we can see that left side is not equal to right side
so, this is FALSE
(c)
We can use independent events formula
P(E∩A)=P(E)*P(A)
we are given
P(E)=0.5
P(A)=0.6
P(E∩A)=0.3
now, we can plug these values into formula
and we get
0.3=0.5*0.6
0.3=0.3
we can see that both sides are equal
so, this is TRUE
(d)
We can use independent events formula
P(D∩B)=P(D)*P(B)
we are given
P(D)=0.25
P(B)=0.4
P(D∩A)=0.15
now, we can plug these values into formula
and we get
0.15=0.25*0.4
0.15=0.1
we can see that left side is not equal to right side
so, this is FALSE
Answer:
12 meters
20cm*60 = 1200cm = 12 meters
100cm = 1m btw
The value of y is 116 degrees
<h3>How to solve for y?</h3>
To solve for y, we make use of the following angle theorem.
The angle at the center is twice the angle at the circumference.
So, we have:
y = 2 * 58
Evaluate the product
y = 116
Hence, the value of y is 116 degrees
