Answer:
11/12
Step-by-step explanation:
55/60 reduced by a factor of 5 becomes 11/12
Answer:
The shape of the graph of f(x)=x is that of a linear function.
Step-by-step explanation:
The graph f(x)=x is the parent function of the linear function. It is a positive function since it goes upward from left to right, and it passes through the point of (0,0). It also has a slope of 1, which is the slope of the parent function, or the graph of f(x)=x. Note once again: The parent linear function and the graph of f(x)=x are the exact same graph.
4 and 5 both go into 20
1/4 equals 5/20
2/5 equals 8/20
So 2 and 5/20 + 1 and 8/20 is
3 and 13/20
Answer:
1. Lateral: 72 SA: 142
2. SA: 36 Lateral: 24
Step-by-step explanation:
1. perimeter of base times the height
2l+2w x h
2(5) + 2(7) x 7
24 x 3 = 72
Surface area: A=2(wl+hl+hw)=2·(7·5+3·5+3·7)=142
2. Surface Area
Using the formulas
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving forA
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=5·2+4·2+3·2+1
2·﹣54+2·(5·4)2+2·(5·3)2﹣44+2·(4·3)2﹣34
=36
Lateral: A=(a+b+c)h=(5+4+3)·2=24
Answer:
The probability is
Step-by-step explanation:
From the question we are told that
The number of green marbles is
The number of red marbles is
The number of red marbles is
Generally the total number of marbles is mathematically represented as
Generally total number of marbles that are not red is
=>
=>
The probability of the first ball not being red is mathematically represented as
=>
The probability of the second ball not being red is mathematically represented as
=> (the subtraction is because the marbles where selected without replacement )
=>
The probability that the first two balls is not red is mathematically represented as
=>
=>
The probability of the third ball being red is mathematically represented as
(the subtraction is because the marbles where selected without replacement )
=>
Generally the probability of the first two marble not being red and the third marble being red is mathematically represented as
=>
