Mathematics
1 answer:
mylen [45]3 years ago
8 0

Answer:

Step-by-step explanation:

the range is written as (min y value, max y value)

the domain is written as (min x value, max x value)

question 6

the min y value on the picture is -3, while the arrows point upward, so the max is infinity, so the domain is [-3,∞), with a bracket on -3 because -3 is included

[-3,∞)

question 7

the min x value is the leftmost point, which is at x = -3, while the max is the rightmost point at x = 3, and both are included in the domain so there should be brackets on both

[-3,3]

question 8

the arrow on the left points to the left and up infinitely, so the min is -∞, the arrow on the right points to the right and up infinitely, so the max x value is ∞

(-∞,∞)

question 9

the min value is the bottommost point at y = -2, and the arrow points upward infinitely so the max y value is ∞

[-2,∞)

question 10

the arrow on the left points to the left infinitely so the min x value is -∞, the arrow on the right points to the right infinitely so the max x value is ∞

(-∞,∞)

What is the what is the answer
ElenaW [278]
The answer would be D. 18/6. We can figure this out because in the question, it says that each shape is worth one whole. There are three shapes so that means when added, the sum is 3 and 18/6, when reduced is 3.
I hope this helped! :-)

Mollie watches a film that lasts 130 min it begins at 6:15 pm. What time did it end?
Natalka [10]
Answer:

Starts at 6:15

Note: An hour is 60 minutes.

So an hour after 6:15 is 7:15 and an hour after that is 8:15. Now just add another 10 minutes and you get 8:25.

So the film ended at 8:25.

Find an equation for the perpendicular bisector of the line segment whose endpoints are (5, -9) and (-9, -5).​
GrogVix [38]

Answer:

y = x - 9

Step-by-step explanation:

Find the slope of the first line.

(-9 + 5)/(5 + 9)

-1

Lines perpendicular have opposite reciprocal slopes

1

Find the middle point of the first line, this is where it will intersect with the bisector.

5 + - 9/2 = 2

-5 + -9/2 = -7

(2,-7) is the midpoint

Use Point Slope Form to reduce it to Standard Form

y + 7 = 1(x - 2)

y + 7 = x - 2

y = x - 9

Consider the experiment of rolling a pair of dice. Suppose that we are interested in the sum of the face values showing on the d
AlekseyPX

Answer:

Step-by-step explanation:

a) the sample point of the random experiment is 36

b) (1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

   (2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

   (3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

   (4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

   (5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

   (6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

Only (1,1) will sum to give 2.

(1,2) and (2,1) will sum up to give 3.

(1,3), (2,2) (3,1) will sum up to give 4.

(1,4) (2,3) (3,2) (4,1) will sum up to give 5.

(1,5) (2,4) (3,3) (4,2) (5,1) will sum up to give 6

(1,6) (2,5) (3,4) (4,3) (5,2) (6,1) will sum up to give 7

(2,6) (3,5) (4,4) (5,3) (6,2) will sum up to give 8

(3,6) (4,5) (5,4) (6,3) will sum up to give 9

(4,6) (5,5) (6,4) will sum up to give 10

(5,6) (6,5) will sum up to give 11

(6,6) 1ill sum up to give 12.

c) probability of obtaining a value of 5 = (number of possible times 5 will occur)/ (total outcome) = \frac{4}{36} =\frac{1}{9}

d) probability of obtaining a value of 8 or greater = \frac{15}{36} = \frac{5}{12}

e) yes, since the total number is 11 and probability of obtaining odd number is \frac{5}{11} and probability of obtaining even number is \frac{6}{11}.

P(odd)\neqP(even)

f) emprical method was used
