Answer:
47
Step-by-step explanation:
Remember triangle always equal to 180
180=70+4x-5+6x-15
x=13
4(13)-5
47
Angle A is 47
Answer:
(a) 0.1666 (b) 0.5 (c) 0.166
Step-by-step explanation:
A die is rolled so sample space = { 1,2,3,4,5,6 } so n=6
(a) the number showing is four so expected value is only 4 so favorable outcomes {4}
so probability 
(b) the number showing an even number
so favorable outcomes= { 2,4 ,6 }
so probability 
(c) the number showing greater than 5 that is only {6}
so probability 
The number of green marbles should expect after 400 trials = 250
(2.5×10⁻⁸)(9×10⁻¹⁰) = 2.5×9×10⁻⁸⁻¹⁰ = 22.5×10⁻¹⁸
= 2.25×10⁻¹⁷
_____
The rules of exponents apply.
... 10^a × 10^b = 10^(a+b)
... 22.5 = 2.25 × 10¹
Answer:
y = 5x + 3
Step-by-step explanation:
When x = 0 y = 3 so the y-intercept will be 3
And the equation is y = 5x + 3 where the slope is 5
