Alecsey [184]3 years ago

7 0

Answer:

A, C and D are continuous

Step-by-step explanation:

A is a set of any number x which 30 < x <=45

B is a set that contains only 3 and 7

C is a set of any number x which 60 <= x < 100

D is a set of any number x which -infinity < x < + infinity

E is a set that contains only even whole numbers

A continuous data set is a quantitative data set representing a scale of measurement that can consist of numbers other than whole number, like decimals and fractions.

Answer:

20 hours

Step-by-step explanation:

first calculate volume:

12x10x3=360

then divide by 18

360/18=20

So 20 hours in total

What are the coordinates of point S"? (negative three-halves, nine-halves) (negative nine-halves, fifteen-halves) (nine-halves,

kow [346]

Answer:

$S=(\frac{9}{2},-\frac{3}{2})$

Step-by-step explanation:

The missing details are:

$T= (0,4)$

$M = (\frac{9}{4}, \frac{5}{4})$ --- Midpoint of ST

Required

Determine the coordinates of S

To do this, we apply the mid-point formula:

$M(x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)$

Where

$M(x,y) = (\frac{9}{4}, \frac{5}{4})$

$T(x_1,y_1) - (0,4)$

The equation becomes:

$M(x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)$

$(\frac{9}{4},\frac{5}{4}) = \frac{1}{2}(0+x_2,4+y_2)$

$(\frac{9}{4},\frac{5}{4}) = \frac{1}{2}(x_2,4+y_2)$

Multiply through by 2

$2*(\frac{9}{4},\frac{5}{4}) = 2*\frac{1}{2}(x_2,4+y_2)$

$(\frac{9}{2},\frac{5}{2}) = (x_2,4+y_2)$

By comparison:

$x_2 = \frac{9}{2}$

$4 + y_2 =\frac{5}{2}$

$y_2 =\frac{5}{2}-4$

$y_2 =\frac{5-8}{2}$

$y_2 =-\frac{3}{2}$

Hence, the coordinates of S is:

$S=(\frac{9}{2},-\frac{3}{2})$

In one hour Dele walks 8km. How long will it take her to walk 14km at the same rate?

denis-greek [22]

Answer:

1.45 h

Step-by-step explanation:

common factor of 8 and 14 is 2.

every 2km dele takes 15 minutes.

we know this because 15 minutes is 1/4 of an hour and 2km is 1/4 of 8km

14km/2km = 7

7*15 minutes = 1.45 hours
