so it's A?

10, D

Multiples of 5  =  5  and 10

Ways to roll a 5  =  (1,4) ( 4,1)  (2,3) (3,2)

Ways to roll  a 10   =  (5,5) (4,6) (6,4)

We have  7  possible outcomes for a multiple of 5...and there are   36  possible outcomes in total 

So  P (multiple of 5)    = 7 / 36

it's 18

Is it C??

is it C or D

Don't know much about this, NSS...but...apparently the "formula" for calculating  APY  is :

APY   = ( 1 + r/n)^n   -1

Where, in our case....r = 12%  = .12   and  n  = 12

So

APY  = (1 + .12 / 12)^12  - 1   ≈  .1268  ≈  12.68%

It's B!!

 In the  formula 

P  = 3500

r = .027

n = 1    [interest is compounded once a year ]

t = 3

So we have 

 A  = 3500 ( 1 + .027/ 1 )^(1*3)   = $3791.22  ⇒ "B" 

I  = Prt

I  = 6000 * (.07) * (4)  = $1680 ⇒ "B"

C = good

Please help asap >.<

I believe that  "3"  is the answer

The mode  is/are the value(s) that occur the most number of times

"7" appears 3 times....does another value appear a greater number of times  ???

Which one is this, NSS ???

Order the data from low to high

Subtract the lowest value from the highest.....this will be the range, NSS

Order the data from low to  high

6  6   7   7   7  9  10  10  10  10  11   12

We have an even number of values

The median is found  by adding the 6th and 7th values  and dividing this sum by 2

Can you find the median based on this, NSS ??

Order the data from low to high

(25   35    45   50)   60    (80   90   95   100)

The median  is 60

The median of the data grouping in the parentheses to the right  of this  gives us the third quartile value

Do you know how to get the median of this grouping, NSS ???

OK, NSS...to find the mean......add the calories  and divide by  4

If you want to post your answer...I'll double-check it...

Edit to correct an earlier mistake...

Order the data from  lowest to highest

(1  3    4   5    6)  ( 7   8   8   8   10 )

The median  is  [ 6 + 7] / 2 =  13/2  = 6.5

The median of the data group in the left set of parentheses is   4  = 1st quartile

The median of the data group in the second set of parentheses is 8  = 3rd  quartile

The interquartile range is    8 - 4  = 4

We can see that two of the points that the line goes through are  (0, -1)  and  (1, 5)  .

slope of line that goes through   (0, -1)  and  (1, 5)   =  \(\frac{\text{rise}}{\text{run}}\,=\,\frac{y_2-y_1}{x_2-x_1}\,=\,\frac{5--1}{1-0}\,=\,\frac{5+1}{1}\,=\,\frac61\,=\,6\)

Also, you can count how many units up and right a point on the line is from another to find the slope.

The point  (1, 5)   is  6  units up and  1  unit right from the point  (0, -1)  ,

so the slope is  6/1 ,  which is  6 .

h(t)    =-3t^2  + 12t + 60

Let h(t)  = y

We want the form

y  = a (x - h)^2  + k      where k  will give us the max  height

Factor out the  -3

y  = -3 (t^2 - 4t - 20)          take 1/2 of 4  = 2...square it = 4 ...  add and subtract this within the parentheses

y = -3 ( t^2  - 4t + 4  - 20  - 4)  simplify within the parenthese

y = -3 (t^2 - 4t + 4   - 24)      factor the first three terms

y = -3 [ (t - 2)^2  - 24 ]     distribute the "-3"  across the terms in the bracket

y = -3 (t - 2)^2  + 72

k = 72  =  max ht  (in feet)

First....find the mean  =   [ 4 + 16 + 21 + 32 + 11 + 12 ] / 6   = 16

Calculate the sum of the squared differences between the mean and each data point

(4 - 16) ^2   = (-12)^2  = 144

(16 - 16)^2  = 0^2  = 0

(21 - 16)^2  = 5^2  = 25

(32 - 16)^2  = 16^2  = 256

(11 - 16)^2  = (-5)^2  = 25

(12 - 16)^2  = (-4)^2  = 16

Add these  =  144 + 0 + 25 + 256 + 25 + 16  = 466    

The variance  =  √ [ 466  /  nuumber  of data points ]   =  √ [466/6 ]  ≈  8.81

We can solve the first with the mid-point formula

The x coordinate of the other unknown point can be found as

(2 + x) / 2  =  -1   multiply both sides by 2

2 + x  =  -2    subtract 2 from both sides

x  = -4

Since only one answer has -4 as the x coordinate, the answer must be  (-4, -2)  ⇒ "H"

For the second  x^3 - 64  factors as a difference of cubes  =

(x - 4) (x^2 + 4x  + 16)

So  (x - 4)  is a factor and  "A"  must be correct
