An employment agency specializing in temporary construction help pays heavy equipment operators $138 per day and general laborers $87 per day. if thirty-three people were hired and the payroll is $4044? How many heavy equipment operators were employed? How many laborers were employed?
1/r = (3 1/2)/245
(3 1/2)r = 245
r = 245/3 1/2
r = 70
scale is 1 in to 70 miles.
Answer:
x + x + 2
Step-by-step explanation:
cuz if its consecutive odd then its every 2 numbers so if x = 3 then you add two to x
Answer:
<h2>One of them i believe is 2 (3+4m) and another one is 6+8m</h2>
Step-by-step explanation: so for the first one you have your equation 18+4(m-3)+4m you take the second part and do 2(9+2(m-3)+2m) then after that you get 2(9+2m-6+2m) and you get you first answer 2(3+4m)
Your second probelm 6+8m you have your equation 18+4(m-3)+4m you do 18+4m-12+4 and you subtract all th likes terms so you get 6+8m
Hope this helps!
Using the principle of binomial probability, the probability of having exactly two black cards is 0.3125
- <em>Probability</em><em> </em><em>of</em><em> </em><em>having</em><em> </em><em>a</em><em> </em><em>black</em><em> </em><em>card</em><em> </em><em>=</em><em> </em><em>26</em><em>/</em><em>52</em><em> </em><em>=</em><em> </em><em>1</em><em>/</em><em>2</em><em> </em>
<u>Using the binomial probability relation</u> :
- P(x = x) = nCx * p^x * q^(n-x)
- <em>p</em><em> </em><em>=</em><em> </em><em>probability</em><em> </em><em>of</em><em> </em><em>success</em><em> </em><em>=</em><em> </em><em>1</em><em>/</em><em>2</em><em> </em><em>=</em><em> </em><em>0</em><em>.</em><em>5</em>
- <em>Number of</em><em> </em><em>picks</em><em>,</em><em> </em><em>n</em><em> </em><em>=</em><em> </em><em>5</em>
- <em>q</em><em> </em><em>=</em><em> </em><em>1</em><em> </em><em>-</em><em> </em><em>p</em><em> </em><em>=</em><em> </em><em>0.5</em><em> </em>
- <em>x</em><em> </em><em>=</em><em> </em><em>2</em><em> </em>
Hence,
P(x = 2) = 5C2 × 0.5² × 0.5³
P(x = 2) = 10 × 0.25 × 0.125
P(x = 2) = 0.3125
Hence. Probability of having exactly 2 black cards is 0.3125
