Answer:

The answer is 2.

Step-by-step explanation:

Remeber to always use PEMDAS.

1. (3 + 5) / x = 4 - We do the addition in the parenthesis first.

2. 8 / x = 4 - We now want to find what x means, to do this we divide the answers by the number we already have.

3. 8 / 4 = 2 - Now we can do the initial equation with the number we found to test it.

4. 8 / 2 = 4 - Simple as that :)

Which is the graph of g(x)=10/x

crimeas [40]

Answer:

Check the attached graph

Step-by-step explanation:

Given equation is $g\left(x\right)=\frac{10}{x}$ .

Now we need to graph the given equation $g\left(x\right)=\frac{10}{x}$ ..

Clearly it is not linear as equation is not of the form $y=mx+b$ . So we need to find some points on given equation $g\left(x\right)=\frac{10}{x}$ . by plugging some random values of x like -5,-3,1,... etc.

for x=-5, we get:

$g\left(x\right)=\frac{10}{x}$

$g\left(-5\right)=\frac{10}{-5}=-2$ .

Hence first point is at (-5,-2). Similarly we can find more points and graph those points.

x can't be 0 as division by 0 is not defined so it will have vertical asymptote at x=0.

Since degree of numerator is less than degree of denominator so y=0 will be horizontal asymptote.

Now join those points by a curved line to get final graph.

A puppy and a kitten are 180 meters apart when they see each other. The puppy can run at a speed of 25 m/sec, while the kitten c

ser-zykov [4K]

Answer: 36 sec

Step-by-step explanation:

Let

x------> distance the kitten runs before being caught by the puppy

Remember that

The speed is equal to divide the distance by the time

v=d/t

solve for t

t=d/v

equate the time

x/20=(180+x)/25

25x=20(180+x)

25x=3,600+20x

25x-20x=3,600

x=3,600/5=720 m

t=d/v=720/20=36 sec

t=(720+180)/25=900/25=36 sec

A class survey in a large class for first-year college students asked, “About how many minutes do you study on a typical weeknig

Anika [276]

Answer: (110.22, 125.78)

Step-by-step explanation:

The confidence interval for the population mean is given by :-

$\mu\ \pm z_{\alpha/2}\times\dfrac{\sigma}{\sqrt{n}}$

Given : Sample size = 463

$\mu=118\text{ minutes}$

$\sigma=65\text{ minutes}$

Significance level : $\alpha=1-0.99=0.01$

Critical value : $z_{\alpha/2}=z_{0.005}=\pm2.576$

We assume that the population is normally distributed.

Now, the 90% confidence interval for the population mean will be :-

$118\ \pm\ 2.576\times\dfrac{65}{\sqrt{463}} \\\\\approx118\pm7.78=(118-7.78\ ,\ 118+7.78)=(110.22,\ 125.78)$

Hence, 99% confidence interval for the mean study time of all first-year students = (110.22, 125.78)

Answer:

x = 8

Step-by-step explanation:

you have similar triangles here

so 2 is to 4 as 4 is to x

2/4 = 4/x

x = 8
