Jar 1 : 16 red, 4 blue....total = 20
P(blue) = 4/20 reduces to 1/5
jar 2 : 75 white,25 blue...total = 100
P(blue) = 25/100 reduces to 1/4
P(blue,blue) = 1/5 * 1/4 = 1/20 or 0.05 or 5%
20x2 = 40 in width
180-40= 140
140/2=70
70 inches
Answer:
B, $35.20
Step-by-step explanation:
32 increase 10% =
32 × (1 + 10%) = 32 × (1 + 0.1) = 35.2
Answer:
31.9secs
6,183.3m
Step-by-step explanation:
Given the equation that models the height expressed as;
h(t ) = -4.9t²+313t+269
At the the max g=height, the velocity is zero
dh/dt = 0
dh/dt = -9,8t+313
0 = -9.8t + 313
9.8t = 313
t = 313/9.8
t = 31.94secs
Hence it takes the rocket 31.9secs to reach the max height
Get the max height
Recall that h(t ) = -4.9t²+313t+269
h(31.9) = -4.9(31.9)²+313(31.9)+269
h(31.9) = -4,070.44+9,984.7+269
h(31.9) = 6,183.3m
Hence the maximum height reached is 6,183.3m
