<span>.. P(at least 2 of 3 baskets) 
= P(2 of 3 baskets) + P(3 of 3 baskets) 
= (basket)(basket)(no basket) + (basket)(no basket)(basket) + (no basket)(basket)(basket) + (basket)(basket)(basket) 
= (0.8)(0.8)(0.2) + (0.8)(0.2)(0.8) + (0.2)(0.8)(0.8) + (0.8)(0.8)(0.8) 
= 3(0.8)(0.8)(0.2) + 0.8^3 
= 0.384 + 0.512 
= 0.896

Answer:

0.64

Step-by-step explanation:

He makes two from three throws, so he makes three throws or two throws.

We add the probabilities:

0.2*0.8^2+0.8^3

then this is equal to 0.64.

HELPPPPPPPP PLSSSS I HAVE 30 BEFORE THIS IS DUE

Answer:

The line equation in slope-intercept form is:

y\:=-\frac{2}{5}x+4

Hence, option D is true.

Step-by-step explanation:

Given the points

  • (0, 4)
  • (5, 2)

Finding the slope between the points

\left(x_1,\:y_1\right)=\left(0,\:4\right),\:\left(x_2,\:y_2\right)=\left(5,\:2\right)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

m=\frac{2-4}{5-0}

m=-\frac{2}{5}

As the y-intercept is obtained by setting the value x = 0.

As we know that when x = 0, the vale of y-intercept y = 4

so the y-intercept is b = 4.

As the slope-intercept form is

substituting the slope m = -2/5 and the y-intercept b=4

y  = mx+b

y\:=-\frac{2}{5}x+4

Therefore, the line equation in slope-intercept form is:

y\:=-\frac{2}{5}x+4

Hence, option D is true.
