Two families are going sailing. Family A leaves the marina and sails 2.3 miles due north, then sails 3 miles due west. Family B leaves the marina and sails 2.3 miles due south, then sails 3 miles in a direction 1° north of due east.
Which family is farther from the marina? Explain your reasoning.
Answers
Answer:
A
Step-by-step explanation:
We can solve this by drawing it out
Family B has part of their north-south direction negated by going 1 degree north of east, because they are going south and then going north. Family A does not do this, and as a result, with all else equal, they go further away.

Ajay is going to invest his money into 2 different stocks. Both stocks are independent, and each stock has a 50%
chance of being successful and a 50% chance of failing.
Each stock will make Ajay $500 if it succeeds or lose him $500 if it fails.
If X is a random variable that represents Ajay's profit from investing in these 2 stocks, drag the bars to graph
the probability distribution for all possible values of X.
Answers
The bar graph represents the value of Profit (X) for the different probabilities of stocks x and y.
It can be drawn as follows.
Let x and y denote the two stocks .
The probability of success of x is p=50%= 50/100=1/2 = 0.5
The probability of failure of x is q= 50%= 50/100= 1/2= 0.5
Similarly
The probability of success of y is p=50%= 50/100=1/2 = 0.5
The probability of failure of y is q= 50%= 50/100= 1/2= 0.5
Then their joint distribution can be calculated from the following table.
x 0.5 0.5 h(y)
y
0.5 0.25 0.25 0.5
0.5 0.25 0.25 0.5
g(x) 0.5 0.5 1.0
It is evident from the data that x and y have the same probability at each point when both x and y are at
successfailuresuccess and failurefailure and successBut the random variable X will have different values for
both success = $500+ $500= $ 1000 both failure = -$500+ -$500= $- 1000success and failure = $500+ $-500= $0failure and success = $-500+ $500= $ 0For the bar graph click

Cube A has a volume of 9 in3. Cube B has a volume of 5 in3. Which of the following expresses the ratio of the side length of Cube A to the side length of Cube B?
(A) 3 : 5 ^1/3
(B) 5^1/3 : 3^1/3
(C) 3^1/3 : 5^2/3
(D) 3^1/3 : 5^1/3
(E) 3^2/3 : 5^1/3
Answers
Using the formula for the volume of a cube, it is found that the expression which gives the ratio of the side length of Cube A to the side length of Cube B is:
[tex]r = \frac{3^{\frac{2}{3}}}{5^{\frac{1}{3}}}[/tex]
Which means that option E is correct.
The volume of a cube of side length l is given by:
[tex]V = l^3[/tex]
For Cube A, the volume is of 9 cubic inches, hence:
[tex]l_a^3 = 9[/tex]
[tex]l_a = \sqrt[3]{9}[/tex]
[tex]l_a = 9^{\frac{1}{3}}[/tex]
[tex]l_a = 3^{\frac{2}{3}}[/tex]
For Cube B, the volume is of 5 cubic inches, hence:
[tex]l_b^3 = 5[/tex]
[tex]l_b = \sqrt[3]{5}[/tex]
[tex]l_b = 5^{\frac{1}{3}}[/tex]
Then, the ratio is:
[tex]r = \frac{l_a}{l_b} = \frac{3^{\frac{2}{3}}}{5^{\frac{1}{3}}}[/tex]

Write equations for the horizontal and vertical lines passing through the point (4-1)
Answers
Answer:
y = - 1 , x = 4
Step-by-step explanation:
The equation of a horizontal line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (4, - 1 ) with y- coordinate - 1 , then
y = - 1 ← equation of horizontal line
The equation of a vertical line parallel to the y- axis is
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (4, - 1 ) with x- coordinate 4 , then
x = 4 ← equation of vertical line

17.31 x____=173.1 decimal math
Answers
10.
Step-by-step explanation:In order to find the missing value, we need to divide 173.1, by 17.31:
173.1 / 17.31 = 10
Dividing the product (173.1) by one value in the equation (17.31) can represent what the missing value is, in order for 17.31 to equal 173.1
Check:
17.31 · 10 = 173.1
173.1 / 10 = 17.31

Find the coordinates of the point 7/10 of the way from A to B
Answers
Answer:
D = (9,4) - (-4, -7) = (13,11) where D is length of line between A and B
.7 D = (9.1, 7.7) since .7 * 13 = 9.1 and .7 * 11 = 7.7
Thus we merely need to add these amounts to point A
(-4, -7) + (9.1, 7.7) = (5.1, .7) for the final coordinates
