Let’s define our variables: x represents child passes and y represents adult passes.

Now, let’s make some equations with the provided information.

First, let’s deal with the money

12x+15y=4140

Next, the amount of passes

x+y=300

Then, take the second equation, and subtract y over.

x=300-y

Now, we can substitute the equation above in for x in the first equation

12x+15y=4140
12(300-y) +15y =4140

Distribute the 12

3600-12y+15y=4140

Combine like terms, then subtract 3600 over

3y=540

Divide by 3 on both sides

y=180

So, 180 $15 entry passes were sold

Taylin buys 5 ounces of tea leaves for $2.35. At this rate, how much money does

Cerrena [4.2K]

Answer:

Step-by-step explanation:

to find the solution, first we need to find the rate per oz. For 5 ounces it is 2.35 so to find the rate per oz we need to find the solution to 2.35/5

$2.35/5=.47$

tea leaves sell at a rate of 47 per oz

Now to find how many Taylin needs for 12 oz of tea we simply multiply .<em>47</em> by 12

0.47 x 12=5.64

Taylin needs $5.64 to buy 12 ounces of tea leaves

In the past few years, outsourcing overseas has become more frequently used than ever before by U.S. companies. However, outsour

Sliva [168]

Answer:

P(X=5)=0.1032

Step-by-step explanation:

This variable can be modeled by a binomial distribution, with parameters n=15 (sample size) and p=0.2 (the individual probability that the company use a consultant).

The probability that k companies that outsource overseas use a consultant can be written as:

$P(x=k) = \dbinom{n}{k} p^{k}(1-p)^{n-k}\\\\\\P(x=k) = \dbinom{15}{k} 0.2^{k} 0.8^{15-k}\\\\\\$

Then, the probability that exactly five companies that outsource overseas use a consultant is:

$P(x=5) = \dbinom{15}{5} p^{5}(1-p)^{10}=3003*0.0003*0.1074=0.1032\\\\\\$

Math help pls o; will reward

BabaBlast [244]

Answer:

see explanation

Step-by-step explanation:

Expressing as equations

9x + 10y = 297 → (1) ← that is B

8x + 5y = 194 → (2) ← that is D

To solve the system of equations, multiply (2) by - 2

- 16x - 10y = - 388 → (3)

Add (1) and (3) term by term to eliminate the term in y

(9x - 16x) + (10y - 10y) = (297 - 388), that is

- 7x = - 91 ( divide both sides by - 7 )

x = 13

Substitute x = 13 into either of the 2 equations and solve for y

Using (1), then

(9 × 13) + 10y = 297

117 + 10y = 297 ( subtract 117 from both sides )

10y = 280 ( divide both sides by 10 )

y = 28
