1.25s+y=t
a= fair admission
1.25s=amount spent on tickets for rides
t=total
Example
1.25*25+y=t
31.25+y=43.75
y=12.50
If you multiply the price of the ride tickets by the amount bought then subtract it from the amount spent total you get the admission price. You can use this equation for anyone who only pays for the rides and fair admission

Suppose a normal distribution has a mean of 266 and a standard deviation of
Jet001 [13]

Answer:

P(x>278) is 0.16

Step-by-step explanation:

We are given that a normal distribution has a mean of 266 and a standard deviation of  12.

Mean = \mu =266

Standard deviation =\sigma = 12

We are supposed to find P(x > 278)

So, Formula : Z=\frac{x-\mu}{\sigma}

Z=\frac{278-266}{12}

Z=1

Refer the z table for p value

p value = 0.8413

P(x<278) is 0.84

P(x>278)=1-P(x<278)=1-0.84=0.16

Option A is true

Hence P(x>278) is 0.16

If f(x) = 7 + 4x and g(x)=1/2x, what is the value of (f/g)(5)?
Romashka [77]
<h2>Answer:</h2>

d. \ \boxed{270}

<h2>Step-by-step explanation:</h2>

In this exercise we need to make a division and evaluate the new function at x=5. so we have two functions, namely:

f(x)=7+4x \ and \\ \\ g(x)=\frac{1}{2x}  

Therefore:

f(5)=7+4(5)=27 \\ \\ g(5)=\frac{1}{2\times 5}=\frac{1}{10}

So:

(f/g)(5)=\frac{27}{\frac{1}{10}}=270
