Answer:

6) Total number of students who took the test = 240

7) (2) 90% of the students who took the test ha scored equal or less Sal's score.

Step-by-step explanation:

Formula to calculate 5th percentile

percentile = (# students who scored ≤ 60 / total number of students) * 100

5th = 12/n * 100

5/100 = 12/n

0.05 = 12/n

n = 240

Total number of students who took the test = 240

90th percentile means Sal scored better than 90% of people who took the test.

Divide p(x) = x4 + 6x3 + 7x2 − 6x − 8 by x + 4 and by x − 3 to find the remainder in each case. Make sure to use the remainder t

BARSIC [14]

The remainder theorem says that dividing a polynomial $p(x)$ by $x-c$ leaves a remainder of $p(c)$ . Here, $c=-4$ , then $c=3$ .

$p(-4)=0$

$p(3)=280$

How does the volume of a sphere compare to that of the volume of a cylinder? What would you say the scale factor for Vol sphere:

borishaifa [10]

Answer:

The volume of a sphere is 2/3 times the volume of a similar cylinder

Scale factor : 2/3

Step-by-step explanation:

Let us consider a sphere of radius r. The volume of the sphere will be given as

$V_{s}=\frac{4}{3} \pi r^{3}$

Similarly, let us consider a cylinder with its height being twice the radius of the sphere. We will have its volume given as:

$V_{c}=\pi r^{2}h$

but h = 2r

Hence we have

$V_{c}= 2\pi r^{3}h$

We can divide the two volumes to get a constant that links them together

$\frac{V_{s}}{V_{c}}=\frac{\frac{4}{3} \pi r^{3}}{2\pi r^{3}h}$

this will give us 2/3

Hence the scale factor for Vol sphere: Vol cylinder is 2/3

Distance formula for (0,1) (3,7)

krok68 [10]

if those r coordinates you can use the Pythagorean the to find the distance

plot the point and create a right triangle with the origin

could up the spaces and depending on the number, subtract the side from the hypotenuse or add the sides to find the hypotenuse

then square root both sides
