Mandarinka [93]

Answer:

x = 11 , y = $\frac{8}{3}$

Step-by-step explanation:

The opposite sides of a parallelogram are congruent

For the figure to be a parallelogram , then

ON = LM, that is

5x - 7 = 4x + 4 ( subtract 4x from both sides )

x - 7 = 4 ( add 7 to both sides )

x = 11

and

OL = NM , that is

3y - 4 = x - 7 = 11 - 7 = 4 ( add 4 to both sides )

3y = 8 ( divide both sides by 3 )

y = $\frac{8}{3}$

A large but sparsely populated county has two small hospitals, one at the south end of the county and the other at the north end

mojhsa [17]

Answer:

Follows are the solution to this question:

Step-by-step explanation:

In point a:

Although both variables are non - stationary, for both the respective pmf, multiply all pmf principles. For example:

$\to P(x=0,y=0)=P(x=0)\times P(y=0)$

$X$

$0 \ \ \ \ \ \ \ \ \ \ \ \ \ \ 1\ \ \ \ \ \ \ \ \ \ \ \ \ \ 2\ \ \ \ \ \ \ \ \ \ \ \ \ \ 3 \ \ \ \ \ \ \ \ \ \ \ \ \ \ 4 \ \ \ \ \ \ \ \ \ \ \ \ \ \ pmf Y$

$0 \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.01 \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.02 \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.03\ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.02\ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.02\ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.1$

$Y \ \ \ \ \ \ \ \ \ \ \ 1 \ \ \ \ \ \ \ \ \ \ \ 0.03 \ \ \ \ \ \ \ \ \ \ \ 0.06 \ \ \ \ \ \ \ \ \ \ \ 0.09 \ \ \ \ \ \ \ \ \ \ \ 0.06 \ \ \ \ \ \ \ \ \ \ \ 0.06 \ \ \ \ \ \ \ \ \ \ \ 0.3$

$2 \ \ \ \ \ \ \ \ \ 0.04\ \ \ \ \ \ \ \ \ 0.08\ \ \ \ \ \ \ \ \ 0.12 0.08\ \ \ \ \ \ \ \ \ 0.08\ \ \ \ \ \ \ \ \ 0.4\\\\ 3\ \ \ \ \ \ \ \ \ 0.02\ \ \ \ \ \ \ \ \ 0.04\ \ \ \ \ \ \ \ \ 0.06\ \ \ \ \ \ \ \ \ 0.04\ \ \ \ \ \ \ \ \ 0.04\ \ \ \ \ \ \ \ \ 0.2\\\\pmf X \ \ \ \ \ \ \ \ \ 0.1\ \ \ \ \ \ \ \ \ 0.2\ \ \ \ \ \ \ \ \ 0.3\ \ \ \ \ \ \ \ \ 0.2\ \ \ \ \ \ \ \ \ 0.2$ `

In point b:

$\to P(x$

In point c: $\to P(X+Y$

In point d:

$\to P(X=0,Y=1)+P(X=0,Y=2)+P(X=0,Y=3)+P(X=0,Y=0)+P(X=1,Y=0)+P(X=2,Y=0)+P(X=3,Y=0)+P(X=4,Y=0) \\\\ \to 0.03+0.04+0.02+0.01+0.02+0.03+0.02+0.02=0.19$

Simon score 4x10^2 points in a game. Joe scored 2x10^3 points in the same game. whose score is higher? how much higher?

Alexxandr [17]

Answer:

Joe scored higher by 1600

Step-by-step explanation:

Given

$Simon = 4 * 10^2$

$Joe = 2 * 10^3$

Solving (a): Which is higher?

First, we need to convert both numbers to whole numbers

$Simon = 4 * 100$

$Simon = 400$

$Joe = 2 * 10^3$

$Joe = 2 * 1000$

$Joe = 2000$

2000 is greater than 400;

Hence, Joe score higher

Solving (b): By how much?

We simply calculate the difference

$Difference = Joe - Simon$

$Difference = 2000 - 400$

$Difference = 1600$

Find two different ways to show how you know either 3/4 is greater than 2/3

Fed [463]

You can change them into fractions with the same denominator: multiply 3/4 by 3 and 2/3 by 4

3/4 = 9/12
2/3 = 8/12

You could also convert them to decimals.
3/4 = 0.75
2/3 = 0.667

3/4 is greater than 2/3

Brooke and Lamont ran a half marathon, Brooke finished in 1 hour 45

AURORKA [14]

Answer: brooke had the faster time

Step-by-step explanation:

This is because if you convert 1 hour 45 into minutes it would be stated as 105 minutes and if you do 115 - 105 you are left with 10 which the bigger number is the fastest so it would be brooke the reason I subtracted was to see if they were not similar. Hope this helps :)
