.08x+.05(15000-x)=930
.08x+750-.05=930
.08x-.05x=930-750
.03x=180
X=180/.03=6,000 at 8%
(15000-6000)=9000 at 5%

For this problem, involving a weighted die, assume that the outcomes 1 through 4 are equally likely, that the outcomes 5 through

storchak [24]

Answer:

a. $\frac{3}{14}$

b. $\frac{1}{14}$

Step-by-step explanation:

We are given that a die is rolled

Let x bet the cases in favor of 5.

Number of cases in favor of 6=x

Then according to question

Number of cases in favor of 1=3x

Number of cases in favor of 2=3x

Number of cases in favor of 3=3x

Number of cases in favor of 4=3x

Sum of total cases= $x+x+3x+3x+3x+3x=14x$

Probability of getting 5 = $\frac{x}{14x}=\frac{1}{14}$

Probability of getting 1= $\frac{3x}{14x}=\frac{3}{14}$

1.We have to find probability should be assigned to rolling a 4.

The probability of getting = $\frac{3}{14}$

2.We have to find the probability of rolling 6.

The probability of getting 6= $\frac{1}{14}$

Whats the distance between the points (2, 7) and (2, 15)

sveta [45]

Answer:

The distance between the points (2, 7) and (2, 15) is 8.

Step-by-step explanation:

<u>What is the Distance between Two Points?</u>

For any two points there is exactly one line segment connecting them. The distance between two points is the length of the line segment connecting them. Note that the distance between two points is always positive. Segments that have equal length are called congruent segments.

How to Solve:

Formula:

$\sqrt{(x2-x1)^2+(y2-y1)^2}$

Putting Values:

$=\sqrt{(2-2)^2+(15-7)^2}$

$=\sqrt{(0)^2+(8)^2}$

$=\sqrt{0+64}$

$=\sqrt{64}$

$=8$
