A number cube with the numbers 1 through 6 is rolled.

Mathematics
1 answer:
olchik [2.2K]3 years ago
6 0

Answer:

Step-by-step explanation:

Given that, we have a number cube label 1,2,3,4,5 and 6.

Then, the sample space is

S= {1, 2, 3, 4, 5, 6}

The probability of rolling a number different from 9?

Since we don't have 9 in the sample space, then the probability of rolling a number different from 9 will be the have 1,2,3,4,5 and 6 as the outcome

Then,

Pr(rolling number different from 9) = 6 / 6 = 1

Pr(rolling number different from 9) = 1.

The second option is correct.

Amiraneli [1.4K]

<u>Story Problem</u>

Mr. Bill Gates bought a house in Italy for \$506,211 and a house in Canada for \$424,809. What is the total cost of the two houses?

we know that

The total cost is the sum of the cost each house

so

\$506,211+\$424,809=\$931,020

therefore

the answer is

The total cost is \$931,020

Quadrilateral ABCD is dilated by a scale factor of 1 over 2 centered around (2, 2). Which statement is true about the dilation?
Musya8 [376]

Answer:

Option (1)

1) Segment B'D' will run through (2, 2) and will be shorter than segment BD.

Step-by-step explanation:

The rest of the question is the attached figure (1).

The statement options are:

1) Segment B'D' will run through (2, 2) and will be shorter than segment BD.

2) Segment B'D' will run through (2, 2) and will be longer than segment BD.

3) Segment B'D' will parallel to segment BD and will be shorter than segment BD.

4) Segment B'D' will be parallel to segment BD and will be longer than segment BD.

==============================================================

See the attched figure (2), which represents Quadrilateral ABCD and the image A'B'C'D'

As shown:

The quadrilateral ABCD with vertices A(1,2), B(2,3), C(4,2) and D(2,1).

Quadrilateral ABCD is dilated by a scale factor of 1 over 2 centered around (2, 2).

So,

The quadrilateral A'B'C'D' will be with vertices:

A'= (1.5,2), B'= (2,2.5), C'= (3,2), D'= (2,1.5)

Comparing the options with the figure (2):

So, the answer is option (1)

1) Segment B'D' will run through (2, 2) and will be shorter than segment BD.

I need help with someone explaining how to find the range of this! This course didn’t explain anything!
zaharov [31]

Answer:

(-infinity,3), D

Step-by-step explanation:

3 if x is greater than or equal to 1 is nothing. That leaves us with h(x)=2x+1 if x<1. If you substitute in 1 for x, you get 3, but of course that isn't possible, so the range is (-infinity,3), which is D.
