Any line parallel to this line can be written as y=-2/3x+c and passes through (9,6).thus 6=-2/3(9)+c.c-6=6.c=12.equation is y=-2/3x+12.

Imagine that James has been bowling for over 10 years and never gets any better or any worse. The probability that he will bowl

vichka [17]

Answer:

5.01%

Step-by-step explanation:

In order to calculate a sequence of events you need to multiply the probability of each event happening with one another in decimal form. In this scenario, the probability of James bowling a strike is 55% meaning that the probability of James NOT bowling a strike is 45%. We want to know the probability of James NOT bowling a strike for 3 attempts and then bowling a strike on his fourth attempt. We first turn these probabilities into decimal form by dividing them by 100. And then multiply...

55 / 100 = 0.55

45 / 100 = 0.45

0.45 * 0.45 * 0.45 * 0.55 = 0.05011875

Multiply by 100 to get percentage.

0.05011875 * 100 = 5.01%

Is this relation a function?why or why not?[(-5,7),(-2,1),(0,3),(4,7)]

julsineya [31]

Answer:

No, every relation is not a function.

Step-by-step explanation:

Every function is a relation because there are two points (x,y) somehow related to each other.

But every relation is not a function

The given ordered pairs are the function

Since, we are getting different value of y for ecah x.

The condition for function is we should get different value of y for each x.

Plz help<br>will give the brainliest<br>need step by step explanation

ddd [48]

Answer:

A = 25 units²

Step-by-step explanation:

First, figure out where the lines intersect.

Let's start with x = 0 and y = x:

because x = 0, substitute x in y = x

y = 0 so the intersection point of these two lines is (0,0)

With, x + y = 10 (or y = 10 - x) and x = 0:

substitute x again y = 10 - 0, so y = 10 and the intersection point is (0,10)

The last point has to be found by setting y = x and x + y = 10 (y = 10 - x) equal to each other: x = 10 - x

solve for x: x = 10 - x

2x = 10

x = 5

find y: y = 10 - 5

y = 5 and the intersection point is (5,5)

Now that you have the vertices of the triangle, you can find the area. (0,0) and (0,10) are on the y-axis and has a length of 10 units; this is your base. To find the height, you need to picture the triangle on the coordinate plane. Point (5,5) lines up with the midpoint (0,5) of the side with (0,0) and (0,10). From this, you can see that the height is 5 units.

Use the triangle area formula: A = 0.5bh

A = 0.5(10)(5)

= 0.5 × 50

A = 25 units²

How do we determine the strength of a correlation?

Sladkaya [172]

$\huge\underline{\red{A}\green{n}\blue{s}\purple{w}\pink{e}\orange{r} →}$

Correlation coefficient measures the strength of that relationship.

Calculating a Pearson correlation coefficient requires the assumption that the relationship between the two variables is linear.

The relationship between two variables is generally considered strong when their r value is larger than 0.7.
