In a survey of college students, each of the following was found. Of these students, 355 owned a tablet, 292 owned a laptop, 280

avanturin [10]

Add all the numbers together to find the total amount of college students surveyed.

355 + 292 + 280 + 191 + 198 + 136 + 66 + 24 = 1,542

The number is already simplified considering it's a whole number. The answer is either 1,542 or 1,500

(I say either because when it says to simplify I'm not sure if they want it to be rounded.)

5/8 of the staff are male. 5/12 of the staff works part time at the aquarium. What is the fraction of the staff being a female?

mestny [16]

Answer:3/8

Step-by-step explanation:

5/8 of the staff are male. The entire staff is represented by the fraction 8/8. Taking 5/8 from this, what we have left is

8/8-5/8 = 3/8 of the staff are female.

Find the difference: (6y3 + 17y − 3) − (4y3 − 11y + 9)

earnstyle [38]

(6y3 + 17y − 3) − (4y3 − 11y + 9)
= 6y3 + 17y − 3 − 4y3 + 11y - 9
= 2y3 + 28y - 12

Find the value of n, correct to 4 significant figures.

Law Incorporation [45]

Answer:

6.708

Step-by-step explanation:

Y varies directly as the square of x (Given)

$\implies y\:\alpha \:x^2$ ......(1)

Y varies inversely as the square root of z (Given)
$\implies y\:\alpha\: \frac{1}{\sqrt z}$ ......(2)

Combining (1) & (2), we find:

$y\:\alpha \:\frac{x^2}{\sqrt z}$

$\implies y=\frac{kx^2}{\sqrt z}$ (Where k is constant of proportionality).....(3)

Now, when y = 2, x = 3 and z = 4, we find the value of k i.e. constant.

$2=\frac{k(3)^2}{\sqrt 4}$

$\implies 2=\frac{k(9)}{2}$

$\implies k =\frac{4}{9}$

Plugging the value of k in (3), we find:

$y=\frac{4x^2}{9\sqrt z}$ ....(4)

Next, in equation (4), plug y = 5, x = n and z = 16 and obtain the value of n by solving it.

$5=\frac{4(n)^2}{9\sqrt {16}}$

$\implies 5=\frac{4(n)^2}{9(4)}$

$\implies 5=\frac{(n)^2}{9}$

$\implies 5(9)=(n)^2$

$\implies 45=(n)^2$

$\implies n=\sqrt{45}$

$\implies n=6.70820393$

$\implies n\approx 6.708$
