D. a set of cards has 25 cards with stars, 15 cards with squares, and 10 cards with circles. find the probability of each event
Dvinal [7]

Answer:

look below

Step-by-step explanation:

The probability of each of the cards can be found by dividing each of them by the sum of all the numbers:

P of picking card with star:

25/50=0.5

Card with square:

15/50=3/10=0.3

Card with circle: 10/50=1/5=0.2

We can then put these values into parts a,b,c, and d:

a) 3/10 chance or 30%

b) 1/5 chance or 20%

c) 1/2+1/5=7/10 chance or 70%

d) 1-0.3-0.2=1/2 chance or 50%

need help.. The midpoint of GH is M(-6,-3). One endpoint is H (-4,4) Find the coordinates of endpoint G.
iren2701 [21]

Answer:

The coordinates of G are: (-8, -10)

Step-by-step explanation:

Mid point formula:

x = \dfrac{x_1+x_2}{2}\\y = \dfrac{y_1+y_2}{2}

Where,

(x,y) are the coordinates of the mid point of the points (x_1,y_1)  and (x_2,y_2).

As per question statement, we are given that:

x_2=-4\\y_2=4

and

x=-6\\y=-3

To find:

x_1 = ?\\y_1 = ?

Solution:

Let us use the mid point formula:

-6 = \dfrac{x_1-4}{2}\\\Rightarrow -12=x_1-4\\\Rightarrow x_1=-12+4\\\Rightarrow \bold{x_1=-8}

-3 = \dfrac{y_1+4}{2}\\\Rightarrow -6=y_1+4\\\Rightarrow y_1=-6-4\\\Rightarrow \bold{y_1=-10}

The coordinates of G are: (-8, -10)
