Answer:
X >>>>> Y
–1 >>>> 16
0 >>>>> 8
1 >>>>> 4
2 >>>>> 2
3 >>>>> 1
Step-by-step explanation:
From the question given above,
y = 8 × (½)ˣ
When x = –1, y =?
y = 8 × (½)ˣ
y = 8 × (½)¯¹
y = 8 × 2
y = 16
When x = 1, y =?
y = 8 × (½)ˣ
y = 8 × (½)¹
y = 8 × ½
y = 4
When x = 2, y =?
y = 8 × (½)ˣ
y = 8 × (½)²
y = 8 × ¼
y = 2
When x = 3, y =?
y = 8 × (½)ˣ
y = 8 × (½)³
y = 8 × ⅛
y = 1
SUMMARY:
X >>>>> Y
–1 >>>> 16
0 >>>>> 8
1 >>>>> 4
2 >>>>> 2
3 >>>>> 1
So 1st make it equal to zero
x^2+4x-12
(x+6)(x-2)
so
x=-6 or 2 is the correct answer
Answer:
4/5 * 3/7
To multiply the fractions, multiply the numerators and denominators separately
4*3/5*7
multiply the numbers
12/5*7
multiply the numbers
12/35
hope that helps
Step-by-step explanation:
Answer: 0.500
Step-by-step explanation:
Given : A normal distribution has a mean
of 10 and a standard deviation
of 1.
Let x be a random variable that represents numbers .
The probability of selecting a number that is at most 10 will be
As the area occupied by standard normal curve less than equal to 0 = 0.500
So, required probability = 0.500
