Answer:


choosing 1 red marble

; choosing 1 white marble, replacing it, and choosing another white marble

; and choosing 1 white marble


Step-by-step explanation:


There are 2+3+5 = 10 marbles.  The probability of choosing 1 blue marble is 2/10 = 1/5; this is not greater than 1/5.


The probability of choosing 1 red marble is 3/10; this is greater than 2/10, which is the same as 1/5.


The probability of choosing 1 red marble is 3/10; not replacing it and choosing a blue marble would then be a probability of 2/9.  Together this is a probability of 3/10(2/9) = 6/90 = 3/45; this is smaller than 9/45, which is the same as 1/5.


The probability of choosing 1 white marble is 5/10 = 1/2; replacing it and choosing another white marble would be 1/2.  Together this is a probability of 1/2(1/2) = 1/4; this is greater than 4/20, which is the same as 1/5.


The probability of choosing 1 white marble is 5/10 = 1/2.  This is greater than 2/10, which is the same as 1/5.


hope this helps

Probably the last two, cause there's so many white marbles and there's three red ones so like, you could probably pull a red so that your chance of getting blue in the last answer is higher

Which is the equation in slope-intercept form for the line that passes through (3, 7)
quester [9]

Answer:

y =  -  \frac{5}{3} x + 12

Step-by-step explanation:

First, rewrite the given equation in the form of y=mx+c.

m is the gradient while c is the y-intercept.

3x-5y=8

5y= 3x -8

y =  \frac{3}{5} x -  \frac{8}{5}

Thus, the gradient of the given equation is ⅗.

The product of the gradients of perpendicular lines is -1.

(gradient of line)(⅗) = -1

gradient of line= -1 ÷⅗

gradient of line= -  \frac{5}{3}

y =  -  \frac{5}{3} x + c

To find the value of c, substitute a coordinate.

When x=3, y=7,

7 =  -  \frac{5}{3} (3) + c

7= -5 +c

c= 7+5

c= 12

Hence, the equation of the line is y =  -  \frac{5}{3} x + 12.

Can someone please answer the problem in the picture?
Elenna [48]

Answer:

Rate of change is 6/7      Initial value: 6

Step-by-step explanation:

To find the slope (which is the rate of change), use (y1 - y2)/(x1 - x2).

x1 and y1 will be (0, 6)    

x2 and y2 will be (7, 0)

Note that x1 x2 y1 y2 can be any points on the line, I just chose these because they were x and y-intercepts.

(6 - 0)/(0 - 7)  =  6/7

The initial value is simply the y-intercept, which is 6.
