True.
The rational numbers include all the integers, plus all fractions, or terminating decimals and repeating decimals. ... All natural numbers, whole numbers, and integers are rationals, but not all rational numbers are natural numbers, whole numbers, or integers.
Since he said that ABC = FED = 12
Meaning (A-B/B-C/A-C) dimensions
A-B = 12
B-C = 12
A-C = 12
FED dimensions (E-D/D-F/E-F) = 12
E-D = 12
D-F = 12
E-F = 12
Since A = 25 & F = 4X = 12
A = F (bcz ABC = FED)
Finding value of (X):
Since (A-C) = (F-D) = 12 (ABC = FED)
4X = 12
X = 12/4
X = 3 ... The answer is C)
------
Finding the value of (y):
25 = (4y - 3)
adding (+3) to both sides of equation
25 + (+3) = (4y - 3) + 3
28 = 4y + 3 - 3
+3 -3 = 0
28 = 4y + 0
28 = 4y
So, y = 28/4
y = 7 ... The answer is B)
Here you go, good luck!
Answer:
Step-by-step explanation:
Answer:
0.430 (nearest thousandth)
Step-by-step explanation:
Using binomial probability relation :
p = 0.81
n = 4
x = 4
1 - p = 1 - 0.81 = 0.19
Recall ;
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 4) = 4C4 * 0.81^4 * 0.19^(4-4)
P(x = 4) = 1 * 0.43046721 * 1
P(x = 4) = 0.43046721
P(x = 4) = 0.430 (nearest thousandth)
