Answer:
b. 0.45.
Step-by-step explanation:
The total possible outcome of a probability is 1
Given;
Probability that both lights will be red when she reaches them = 0.22
Probability that the first light will be red and the second light will not be red = 0.33
Probability that the second light will be red when she reaches it = x
These are all the possible outcomes, therefore
0.22 + 0.33 + x = 1
0.55 + x = 1
x = 1 - 0.55
x = 0.45
Option b
Answer:
1
Step-by-step explanation:
y + 14
=> 1(y) + 14
=> Coefficient = 1
Answer:
1a 2a
Step-by-step explanation:
n × (−2+5 ) = −8+20
n × 3 = 12
n = 4
2 + (n+6) = −1+6
n + 8 = 5
n = -3
Answer:
14
Step-by-step explanation:
The applicable rule of exponents is ...
(a^b)(a^c) = a^(b+c)
__
You have ...
(x^3)(x^a) = x^17
x^(3+a) = x^17
Equating exponents, we get ...
3 +a = 17
a = 14
The missing exponent is 14.
