 1) The answer would be $2. You can solve this problem by setting an equation: 20= 7x+6. Subtract 6 from both sides and you get 14= 7x. After that, divide both sides by 7. 14 divided by 7 is two. The answer is 2.


2) The answer would be 29. You can answer this question by setting up the following equation:  x+x+2+x+4=93. For instance, you know that x is an odd number (example lets say its the number 1). The next consecutive ODD number would have to be 3 (following the example given), which can be represented by x+2 (1+2=3). Now, knowing this, the third number can be represented by the expression x+4 (1+4=5, which makes sense as the order of the numbers would now be 1,3,5- consecutive odd numbers). Apply this to the question:   x+x+2+x+4= 93 then becomes 3x+6 after combining like terms. This leaves you with 3x+6=93. Subtract 6 from both sides: 3x=87. Divide both sides by 3: x=29 (the smallest number as the other numbers would be 31 and 33 which you get by plugging in to x+2 and x+4). Finally, you can check your answer by adding all the numbers :-)

3) 8 notepads. The question states that Danielle had $35 and bought 1 magazine (worth $3) and some notepads (each worth $4). You can solve this question by setting up the following equation: 35= 3+4x. Subtract both sides by 3 and you get 32=4x. Divide both sides by 4: 8=x.

4) $20
5) $12
6) 4 candy bars
7) $8
8) 5 hours

A restaurant gat an average of 14 calls in a 2 hr time period. What is the probability that at most 2 calls in 45 min period
rodikova [14]

Answer:

0.10512

Step-by-step explanation:

Given the following :

Mean number of calls(μ) in 2 hours = 14

2 hours = 60 * 2 = 120 minutes

Average number of calls in 45 minutes :

= (45 / 120) * 14

= 0.375 * 14

= 5.25

Now find P( x ≤ 2) = p(x = 0) + p( x = 1) + p(x = 2)

Using the poisson probability formula:

P(x, μ) = [(e^-μ) * (μ^x)] / x!

Where :

e = euler's constant

μ = 5.25

x = 0, 1, 2

Using the online poisson probability calculator :

P(x, 5.25) = P( x ≤ 2) = p(x = 0) + p(x = 1) + p(x = 2)

P(x, 5.25) = P( x ≤ 2) = 0.00525 + 0.02755 + 0.07232 = 0.10512
