Answer:

1/6

Step-by-step explanation:

A regular number cube has 6 different sides, so the probability of it landing on any side is 1/6. There are 6 possible sides, so landing on a 4 is one of the six possible outcomes.

Hope I helped! Good luck!

To verify the identity tan (x1+x2+x3) = tan x1 + tan x2 + tan x3 - tan x1 tan x2 tan x3 / 1 - tan x1 tan x2 - tan x2 tan x3
andrezito [222]

Answer:

The answer is the last one

tan(x_{1}+x_{2}+x_{3})=\frac{tanx_{1}+tan(x_{2}+x_{3})}{1-tanx_{1}tan(x_{2}+x_{3})}

Step-by-step explanation:

∵ tan(x_{1}+x_{2}+x_{3}=\frac{tanx_{1}+tan(x_{2}+x_{3})}{1-tanx_{1}tan(x_{2}+x_{3})}

=\frac{tanx_{1}+\frac{tanx_{2}+tanx_{3}}{1-tanx_{2}tanx_{3}}  }{1-tanx_{1}(\frac{tanx_{2}+tanx_{3}}{1-tanx_{2}tanx_{3}})}

Multiply up and down by 1-tanx_{2}tanx_{3}

\frac{tanx_{1}(1-tanx_{2}tanx_{3})+tanx_{2}+tanx_{3}}{1-tanx_{2}tanx_{3}-tanx_{1}tanx_{2}-tanx_{1}tanx_{3}}

=\frac{tanx_{1}+tanx_{2}+tanx_{3}-tanx_{1}tanx_{2}tanx_{3}}{1-tanx_{1}tanx_{2}-tanx_{2}tanx_{3}-tanx_{1}tanx_{3}}

Brian works at the oil factory. He gets a $45 per day. He gets a 10% pay increase. He wirks 24 days in a month. How much more mo
Artist 52 [7]

Answer:

Net increment = $108

Step-by-step explanation:

Current wage rate for Brian = $45 per day

number of days Brain is working = 24

Total earning in a month = $45 x 24 = $ 1080

Total increment = 10% of $45

= 0.10 x $45 = $4.5

New wage rate for Brain = $45=$4.5= $49.5

No. of working days = 24

New earning per month = $49.4 x 24 = $1188

Total increment in the earning = $1188- $ 1080

= $108
