Answer:

x = 13

Step-by-step explanation:

\frac{2 \frac{1}{3} }{4 \frac{1}{3} }  =  \frac{7}{x}  \\  \frac{7}{3}  \div  \frac{13}{3}  =  \frac{7}{x}  \\  \frac{7}{ 3}  \times  \frac{3}{13}  =  \frac{7}{x}  \\  \frac{7}{13}  =  \frac{7}{x}  \\ 7x = 13 \times 7 \\ x =  \frac{13 \times 7}{7}  \\ x = 13

The function f(x) = 15(2)^x represents the growth of a frog population every year in a remote swamp. Elizabeth wants to manipula
weeeeeb [17]
Half one is 1/2;
half three is 3/2;
Thus, if f(x) represents annual growth, f(x)/2 shows it every half-year, like this:
\dfrac{f(x)}{2} = \dfrac{15\cdot 2^x}{2} \\  \\ 
\dfrac{f(x)}{2} = \dfrac{15}{2}\cdot 2^x

Written in plain text: f(x)=15/2*2^x

An analyst from an energy research institute in California wishes to precisely estimate a 99% confidence interval of the average
Lena [83]

Answer:

190

Step-by-step explanation:

Data provided in the question:

Confidence level = 99%

Therefore,

α = 1% = 0.01

[ from standard normal table ]

z-value for z_{\frac{\alpha}{2}}= z_{\frac{0.01}{2}}= = 2.58

Margin of error, E = $0.06

Standard deviation, σ = $0.32

Now,

n = (\frac{z_{0.005}\sigma}{E})^2

Here,

n is the sample size (or the minimum number of gas stations  )

on substituting the respective values, we get

= (\frac{z_{0.005}\sigma}{E})^2

= (\frac{2.58\times0.32}{0.06})^2

= 13.76²

= 189.3376 ≈ 190

Hence,

minimum number of gas stations that she should include in her sample is 190
