H'(x) = 2f'(x)
h'(1) = 2*f'(1) = 2*4
h'(1) = 8
Answer:
12
Step-by-step explanation:
A 2 - sided counter ; (red, yellow)
A spinner (1,2,3,4,5,6)
Number of trials = 80
P(red and number > 3) :
P(red) = 1/2 ;
P(number >3) : numbers greater Than 3 = (4, 5, 6)
Hence, P(number <3) = 3 /6 = 1/2
Theoretical probability = 1/2 *1/2 = 1/4
Expected number of outcomes :
1/4 * number of trials
1/4 * 80 = 20
Experimental outcome :
Relative frequency = number of outcomes / number of trials
Relative frequency = 2/5
Hence,
2/5 = number of outcomes / 80
Cross multiply :
160 = number of outcomes * 5
Number of outcomes = 160 /5 = 32
Actual outcomes = 32
Difference between actual and expected :
32 - 20 = 12

Answer:
65.93
Step-by-step explanation:
Okay, first lets convert the money.
100 ÷ 1.43 = 69.9300699301 (69.93)
69.93 - 4 = 65.93

Answer:
The strip of 16 by 14 inches.
Let x be the corner of the square cut
Then the box would have height as x, length 16-2x and width 14-2x
Hence volume =
Use derivative to test to find x for maximum volume
V'(x) =
v"(x) =
Equate first derivative to 0
Solutions are
x= 2.483 and x = 7.517
Practically cutting more than 7 inches is not possible from 14 inches dimention
Hence 2.483 is the side of square and maximum volume
= 247.508
Step-by-step explanation:
