What is 15/2 divided by 25/8.

1 answer:

7 0

$\frac{15}{2} \times \frac{8}{25 } = \frac{15}{2} \div \frac{25}{8}$
and 15×8=120 and 2×25= 50
so the answer is
$\frac{120}{50}$
simplifies to
$2 \frac{2}{5}$

If the result is reflected over x-axis and vertically stretched by a factor of 5, the result will be g(x) = -5(x - 1)²

<h3>Transformation of functions</h3>

Transformation is a way of changing the position of an object o the xy plane. Given the parent function expressed as

f(x) = x^2

If the function is shifted to the left by unit, then we will have h(x) = (x - 1)²

If the result is reflected over x-axis and vertically stretched by a factor of 5, the result will be g(x) = -5(x - 1)²

Which value is a solution of the equation 85= 120-w?

Ronch [10]

$85=120-w\\85-120=120-w-120\\-35=-w\\\frac{-35}{-1}=\frac{-w}{-1}\\35=w$

w = 35

The brain volumes (cm cubed) of 20 brains have a mean of 1162.8 cm cubed and a standard deviation of 127.1 cm cubed. Use the g

Free_Kalibri [48]

Answer:

- The limits are 908.6 cm^3 and 1417cm^3

- 1337.0cm^3 is in between the limits

Step-by-step explanation:

To determine the limit by taking into account the range rule of thumb, you use the fact that the limits are given by the mean plus and minus twice the standard deviation, that is:

$\overline{x}\pm 2\sigma$ (1)

$\overline{x}$ : mean of brain volume = 1162.8 cm^3

σ: standard deviation = 127.1 cm^3

You replace the values of the parameters in the equation (1):

$1162.8cm^3+2(127.1cm^3)=1417cm^3\\\\1162.8cm^3-2(127.1cm^3)=908.6cm^3$

Limits = (1417 , 908.6)

The limits are 908.6 cm^3 and 1417cm^3

1337.0cm^3 is in between the limits calculated above.

If a population of 100 cells triples every hour, which function represents p(t), the population after t hours?

tia_tia [17]

Exponential functions are in the form $f(x)=a*b^x$ , where <em>a</em> is the initial value, <em>b</em> is the growth rate (percent increase) + 1, and <em>x</em> is the number of time periods. Our initial value is 100, and we're given the growth rate + 1 (tripling is the same as increasing by 200%; 200%=2.0; 2.0+1=3). Therefore our function is $p(t)=100*3^t$ .
