The sample at option B, {0, 2} is not a part of the sample space of a spinner when spun two times.

<h3>What is a sample space?</h3>

The set consists of all the possible outcomes of an event called sample points, which is said to be a sample space.

<h3>Calculation:</h3>

It is given that,

a spinner has 5 sections of equal area and each section is numbered from 1 to 5.

If the spinner is spun two times, then the possible outcomes are 25. They are:

{(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (5, 1), (5, 2), (5, 3), (5, 4), (5, 5)}

So, from the given options, the sample {0, 2} is not possible since there is no such a section on the spinner named 0.

Which graph represents the solution set to this system of equations? y = –1 2 x + 3 and y = 1 2 x - 1 On a coordinate plane, a l
vivado [14]

Answer:

On a coordinate plane, a line goes through (0, 3) and (2, 2) and another line goes through (0, negative 1) and (2, 0).

Step-by-step explanation:

Given that the system of equations are:

y = –1 /2 x + 3 and y = 1 /2 x - 1

Let us first try the first option

On a coordinate plane, a line goes through (- 4, 1) and (0, 3) and another line goes through (-2, - 2) and (0,- 1)

The slope M1 = (3-1)/(0--4) = 2/4 = 1/2

The calculated slope is positive. But the slope of the first equation is negative. So we ignore the first option.

The next option that makes sense is the last option. That is

On a coordinate plane, a line goes through (0, 3) and (2, 2) and another line goes through (0, -1) and (2, 0). So let also try it by calculating the two slopes

M1 = (2-3)/(2-0) = -1/2 ( perfect)

M2 = (0- -1)/(2-0) = 1/2 (perfect)

Because, from the two equations

y = –1 /2 x + 3 and y = 1 /2 x - 1

The slope of the first is negative and the slope of the second is positive. Also, they have a corresponding intercept which are positive 3 and negative 1

Darren invests $750 in an account that pays 2.5% simple interest for 40 weeks. How much will his investment be worth at the end
Yuliya22 [10]

Answer:

  $764.42

Step-by-step explanation:

The account balance is given by the formula ...

  A = P(1 +rt)

where P is the principal invested, r is the annual rate, and t is the number of years. Here, we assume 52 weeks in the year, since the time period is given in weeks.

Filling in the numbers, we have ...

  A = $750(1 +0.025(40/52)) = $764.42

Darren's investment will be worth $764.42 at the end of 40 weeks.

Solve using your choice of graphing, substitution, or elimination​
antiseptic1488 [7]

Answer:

x = 110, y = 153.

Step-by-step explanation:

4x - 3y = -19   Multiply by 2

3x - 2y= 24    Multiply by 3.

8x - 6y = -38

9x - 6y = 72      SUBTRACT

-x = - 110

x = 110

Substitute for x :

3(110) - 2y = 24

2y =330 - 24

2y = 306

y = 153.
