There are 90 hats all together. from just red the fraction is 20/90. 20 divide by 90 = .22
there is a 22% chance.
Y = mx + b is the format for this equation, where <em>m</em> is the slope and <em>b</em> is the y-intercept. with that information, (-1) would be your slope, taking the assumed coefficient of 1 from the x, and the y-intercept is 5.
Answer:
12 & 18
Explanation:
My Asian friend Ryen, actually just told me answer,so there you go.
Or, 6x2=12
and 6x3=18
That works too
Answer:
0.25feet
Step-by-step explanation:
The equation is not well written. Let the equation of the height be modelled as;
h = -16d²+8d+4
The velocity of the ball is zero at its maximum height.
Velocity = change in displacement/time
v = dh/dd
Differentiate
v = -32d+8
Since dh/dd = v = 0
0 = -32d+8
Add 32d to both sides
0+32d = 8
32d = 8
Divide both sides by 32
32d/32 = 8/32
d = 1/4
d = 0.25feet
Hence the maximum height of the tennis ball is 0.25feet
Note that the modeled equation was assumed. You can apply the same calculation to any equation given
