The entire shape is 50cm squared. Multiply that by twelve, you get 600. Hope that’s right, and it helps!
f(x) = mx + b
m = slope = -5
f(2) = 10 = (-5)(2) + b
b = 10 + 10 = 20
Ans. m=-5, b = 20
Answer:
Step-by-step explanation:
Your question is unclear. What are "major intercepts"?
x²/81 + y²/64 = 1
The major axis is horizontal.
0²/81 + y²/64 = 1
y-intercepts = ±8
x²/81 + 0/64 = 1
x-intercepts = ±9
Answer:
1011011
Step-by-step explanation:
The binary multiplication is pretty much like the decimal one, we have just to remember that in the binary system 1+1 = 10.
First, convert 7 and 13 to binary
7 = 111
13 = 1101
now multiply with the same rules as in decimal
1101x
111
--------------
1101+
1101 +
1101
1111
-------------
1011011
The last row of digits are the carry bits.
So 7*13 = 1101*111(binary) = 1011011 (binary)
Answer:
n = 484
Step-by-step explanation:
If Confidence Interval CI = 95 % then α = 5% and α/2 = 2,5 %
α/2 = 0,0125
MOE for normal distribution is:
MOE = z * σ/√n
For α/2 = 0,0125 ⇒ z(score) = -2,2
MOE = |-2,2| * 4/√n
0,4*√n = 8,8
√n = 8,8 / 0,4
√n = 22
n = 484
