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%

What is the y-intercept?<br> y-3=1\2(x+2)
Margaret [11]
Y-3=1/2(x+2)

To find the y-intercept, we must first get the equation in slope intercept form. Start off by distributing 1/2 into the parentheses.

y-3= 1/2x+1
Add 3 to both sides

y= 1/2x+4

The slope is whatever is in front of x, in this case, 1/2. The y-intercept is the number after that which would be 4

Amrita thinks of a number. She doubles it, adds 9 , divides her answer by 3 and finally subtracts 1 . She obtains the same numbe
maks197457 [2]

Answer:

Amrita's number is 6

Step-by-step explanation:

x               Double the unknown number

2x             Add 9

2x + 9       Divide the answer by 3

2/3x + 3   Subtract 1

2/3x + 2   Set this equal to the original number

2/3x + 2 = x

-2/3x       -2/3x   Subtract 2/3x from both sides

2 = 1/3x   Multiply both sides by 3

6 = x
