Answer:
This is a linear function because there is a common difference of 4
⇒ 2nd answer
Step-by-step explanation:
- In the linear function there is a common difference between each two
consecutive data
- In the exponential function there is a common ratio between each two
consecutive data
- Lats check the data in the data in the table
(x) === 1 ⇒ 2 ⇒ 3
f(x) === 4 ⇒ 8 ⇒ 12
∵ x has consecutive numbers 1 , 2 , 3
∵ 8 - 4 = 4
∵ 12 - 8 = 4
∴ f(x) has a common difference 4
∵ 8 ÷ 4 = 2
∵ 12 ÷ 8 = 1.5
∴ f(x) has no common ratio
∴ The table represents a linear function with common difference 4
This is a linear function because there is a common difference of 4

On average, indoor cats live to 16 years old with a standard deviation of 2.5 years. Suppose that the distribution is normal. Le

Y_Kistochka [10]

Answer:

(a) N (16, 2.5²)

(b) 0.241

(c) Low: 15.4 years

High: 16.6 years

Step-by-step explanation:

The random variable <em>X</em> is defined as the age at death of a randomly selected indoor cat.

(a)

The distribution of X is:

$X\sim N(\mu = 16, \sigma^{2}=2.5^{2})$

(b)

Compute the probability that an indoor cat dies when it is between 17.2 and 19.6 years old as follows:

$P(17.2$

$=P(0.48$

Thus, the probability that an indoor cat dies when it is between 17.2 and 19.6 years old is 0.241.

(c)

Compute the two numbers within which 20% of indoor cats' age of death lies as follows:

$P(x_{1}$

The corresponding value of <em>z</em> is, 0.25.

Compute the value of <em>x</em>₁ and <em>x</em>₂ as follows:

$z=\frac{x_{1}-\mu}{\sigma}\\\\0.25=\frac{x_{1}-16}{2.5}\\\\x_{1}=16+(0.25\times 2.5}\\\\x_{1}=16.625\\\\x_{1}\approx 16.6$ $z=\frac{x_{1}-\mu}{\sigma}\\\\-0.25=\frac{x_{2}-16}{2.5}\\\\x_{2}=16-(0.25\times 2.5}\\\\x_{2}=15.375\\\\x_{2}\approx 15.4$

Low: <u>15.4</u> years

High: <u>16.6</u> years

find the approximate change in the volume of a rectangular solid caused by increasing each side by 5%

Katen [24]

Volume of a rectangular solid is lwh
Increase of 5% make the volume to be 1.05l(1.05w)(1.05)h = 1.157625lwh
which is approximately an increase of 15.8% of the original volume.

Mark reads 42 pages of a book every 3/4 hour. Write an equation that models the relationships between x, the number of hours Mar

Illusion [34]

Answer:

The equation that models the relationships between $x$ , the number of hours Mark reads, and , $y$ the number of pages of the book he reads is:

$y=56x$

Step-by-step explanation:

Given:

Mark reads 42 pages every $\frac{3}{4}$ hour.

The number of hours is given by = $x$

The number of pages is given by = $y$

The equation can be modeled as:

$y=mx+b$

where $m$ represents rate of change and $b$ represents the y-intercept or the initial value.

Rate of change = $=\frac{Change\ in\ y}{Change\ in\ x}=\frac{42}{\frac{3}{4}}=42\times \frac{4}{3}=56$

The initial value $b=0$ as Mark starts reading from 0.

So, the equation is:

$y=56x$
