The table shows the value of an account x years after the account was opened. Based on the exponential regression model, which i

julsineya [31]

Answer:

Correct choice is B

Step-by-step explanation:

The equation of the exponential regression model is $y=a\cdot b^x.$

1. When x=0, $y=a\cdot b^0=a=5,000;$

2. When x=2, then

$y=5,000\cdot b^2=5,510\Rightarrow b^2=\dfrac{5,510}{5,000}=\dfrac{551}{500}=1.102,\ b=\sqrt{1.102}\approx 1.05.$

3. The equation of the function is $y=5,000\cdot (1.05)^x.$ Note that

$y(5)=5,000\cdot (1.05)^5\approx 6,381\approx 6,390;$
$y(8)=5,000\cdot (1.05)^8\approx 7,387\approx 7,390;$
$y(10)=5,000\cdot (1.05)^{10}\approx 8,144\approx 8,150.$

Therefore,

$y(12)=5,000\cdot (1.05)^{12}\approx 8,979\approx 8,980.$

On one day a pet store sells 2 birds 6 gerbils 3 fish and 3 hamsters whats the data and relative frequency as a percent?

bonufazy [111]

Answer:

Birds $F_b=14.3\%$

Gerbils $F_g=42.9\%$

Fish $F_f=21.4\%$

Hamsters $F_h=21.4\%$

Step-by-step explanation:

From the question we are told that:

Sales

Number of birds $n_b=2$

Number of gerbils $n_g=6$

Number of fish $n_f=3$

Number of hamsters $n_h=3$

Generally the frequency for birds $F_b$ is mathematically given b

$F_b=\frac{n_b}{n}*100$

$F_b=\frac{2}{14}*100$

$F_b=14.3\%$

Generally the frequency for Gerbils $F_g$ is mathematically given b

$F_g=\frac{n_g}{n}*100$

$F_g=\frac{6}{14}*100$

$F_g=42.9\%$

Generally the frequency for fish $F_f$ is mathematically given b

$F_f=\frac{n_f}{n}*100$

$F_f=\frac{3}{14}*100$

$F_f=21.4\%$

Generally the frequency for fish $F_h$ is mathematically given b

$F_h=\frac{n_h}{n}*100$

$F_h=\frac{3}{14}*100$

$F_h=21.4\%$
