Answer:
QSR = 68º
Step-by-step explanation:
TSQ + QSR = TSR
15x + (10x - 2) = 173
Combine like terms
25x = 175
Divide both sides by 25
x = 7
QSR = 10x - 2
QSR = 10(7) - 2
QSR = 68º
Answer:
9.3 repeating
Step-by-step explanation:
Answer:
a
b
c
Step-by-step explanation:
From the question we are told that
The rate is = 0.5 / hr
Generally Poisson distribution formula is mathematically represented as
Generally the probability that no error occurred during a day is mathematically represented as
Here t = 1 hour according to question a
So
Hence
=>
Generally the probability that a critical error occurs since the start of a day is mathematically represented as
Here t = 1 hour according to question a
So
Hence
Here
=>
Considering question c
Here t = 2
Gnerally given that the system just started up and an error occurred the probability the next reset will occur within 2 hours
=>
=>
=>
Answer:
a) x=-a, x=a+b
b) x=5/2a, x=1/3b
c) x=1/2a, x=a/a-2
Step-by-step explanation:
a) (x-a)(x-a)-b(x+a)=0
(x+a)(x-a-b)=0
x=-a, x=a+b
b) 3x(2x-5a)-b(2x-5a)=0
(2x-5a)(3x-b)=0
x=5/2a, x=1/3b
c) (2a-4)x^2=a^2(x-1)
(2x-a)(ax-2x-a)=0
Answer:
a. 12s + 19j - 3
36 + 28 - 3 = 61
b.
Shirt (per unit cost):
Before Discount: $12
After Discount: $12 - $3 = $9
Jeans (pair cost):
Before Discount: $19
After Discount: $19 - $3 = $16
(12-3)s + (19-3)j
27 + 32 = $59
