Answer:

4.87

A "1" can be written as 100/100. Since there is only 87/100 we are only 87% or 0.87 to a full 1

Devide 7/24 by 35/48and reduce the quotient to the lowest fraction

liubo4ka [24]

To divide fraction you divide by the reciprocal of the number you are dividing by

so....
7/24 ÷ 35/48 = 7/24 * 48/35

then just simplify

Hope this helps!

The center circle on a playing field has a radius of 7.5m find its circumference

Nady [450]

<h3>Given:</h3>

r= 7.5 m

r= radius

The circumference of the circular playing field.

<h3>Solution:</h3>

$\huge\boxed{Formula:C= 2\pi{r}}$

We'll have to multiply 2, π and radius.

Substitute the values according to the formula.

$C= 2× \pi ×7.5$

$C= 47.12389$

$\large\boxed{C= 47.12 \: m}$

Therefore, the circumference of the circular playing field is 47.12 feets.

A rectangular prism has a width of 16 inches and a length of 10 inches. The volume of the rectangular prism is decreasing at a r

frosja888 [35]

Answer:

-3.47 inches per minute

Step-by-step explanation:

Let the height be 'h' for any time 't'.

Given:

Length of the prism (L) = 10 in

Width of the prism (w) = 16 in

The rate of change of volume of prism is, $\frac{dV}{dt}=-555\ in^3/min$ (The negative sign implies the volume decreases with time.)

Now, rate of change of height of prism = $\frac{dh}{dt}=?$

Length and width remains constant.

Now, we know that, volume of a rectangular prism is given as:

Volume = Length × width × Height

$V=Lwh\\\\V=10\times 16\times h\\\\V=160h$

Now, differentiating both sides with respect to time 't', we get:

$\frac{dV}{dt}=\frac{d}{dt}(160h)$

Plug in the given values and solve for $\frac{dh}{dt}$ . This gives,

$-555=160\times \frac{dh}{dt}\\\\\frac{dh}{dt}=\frac{-555}{160}\\\\\frac{dh}{dt}=-3.47\ in/min$

The negative sign implies the height decreases with time.

Therefore, the the rate of change, in inches per minute, of the height when the height is 3 inches is -3.47 inches per minute.

A marketing research company desires to know the mean consumption of milk per week among males over age 32. A sample of 710 male

nydimaria [60]

Answer:

(4.5, 4.7)

Step-by-step explanation:

Hi!

Lets call X to the consumption of milk per week among males over age 32. X has a normal distribution with mean μ and standard deviation σ.

$X \sim N(\mu, \sigma)$

When you know the population standard deviation σ of X , and the sample mean is $\hat X$ , the variable q has distribution N(0,1):

$q = \frac{\hat X - \mu}{\sigma} \sim N(0,1)$

Then you have:

$P(-k < q$

This defines a C - level confidence interval. For each C the value of k is well known. In this case C = 0.98, then k = 2.326

Then the confidence interval is:

$(4.6 - 2.326*\frac{0.8}{\sqrt{710}}, 4.6 + 2.326*\frac{0.8}{\sqrt{710}})\\ (4.5, 4.7)$
