Answers
Answer:
(i) [tex]\frac{27}{35}[/tex]
(ii) [tex]\frac{8}{35}[/tex]
Step-by-step explanation:
Probability refers to chances of occurrence of any event.
Probability is calculated by dividing number of favorable outcomes by total number of possible outcomes.
Total number possible of outcomes = 350
(i)
Number of favorable outcomes = [tex]65+95+110=270[/tex]
Probability [tex]=\frac{270}{350}=\frac{27}{35}[/tex]
(ii)
Exactly 3 heads is equivalent to no tails.
Number of favorable outcomes = [tex]80[/tex]
Probability [tex]=\frac{80}{350}=\frac{8}{35}[/tex]

Work out the size of angle x
Next to 164 and 90
Answers
Answer:
x=106 degrees
Step-by-step explanation:
I'm going to assume that this is a circle since you didn't give it to me
So you want to add 164 and 90 together and subtract the sum by 360
360-(164+90)=106
So you want to use PEMDAS (order of operations) to solve this
so do what's in the perenthesis first so 164+90=254Then you want to subtract 254 from 360 so 360-254=106x=106 degrees

A worker on the production line is paid a base salary of $170 per week plus $1.21 for each unit produced. Write an equation to represent his earnings of $491.86 for a week when he produced x units. How many units did he produce? Use pencil and paper. If the worker had produced twice that number of units, what would his earnings have been? Show your work.
Answers
Answer:
Part 1)
$170 + $1.21x = $491.86
Part 2)
170 + 1.21x + 491.86
1.21x = 491.86 - 170
1.21 x = 321.86
1.21x/ 1.21 = 321.86/ 1.21
x = 266 units produced
Part 3)
Twice that number of units = 266 x 2 = 532
$170 + ($1.21 x 532) =
$170 + $643.72 = $813.72

estimate a 15% on a dinner bill of $42.58 by first rounding the bill amount to the nearest ten dollars
Answers
Answer:
$6
Step-by-step explanation:
Round $42.58 to the nearest ten dollars to get $40. $40 ÷ 100 = $0.4 so this is one percent. $0.4 × 15 is $6 which is an estimate of 15% of $42.58.
The answer is $6 (unless if you are meant to add this to $42.58 - then the answer would be $48.58 - but I am not sure because of the wording of the question).

Answer:
-17√2 /26 or -0.9247 to the nearest ten thousandth.
Step-by-step explanation:
The hypotenuse of the right triangle in which tan x = 2/3 is √(2^2 + 3^2)
= √13 so sin x = 2/√13 and cos x = 3/√13
sin2x = 2sinxcos
= 2* 2/√13 * 3/√13
= 12/13.
cos2x = cos^2x - sin^2x
= 9/13 - 4/13
= 5/13.
sin(2x + 5π/4)
= sin2x cos5π/4 + cos2x sin5π/4
= 12/13 * -1/√2 + 5/13 * -1/√2
= -12 / 13√2 - 5 / 13√2
= -17/13√2
= -17√2 /26.
