X^2+10x+25= 24+25
(x+5)^2= 49
x+5= +-7 (plus or minus 7)
x= -7-5
x=-12
x=7-5
x=2
Final answer: x={-12, 2}
Answer:
1st question,<u> are you are able to cut the four pieces of licorice?</u> <u>if so cut them into 4 equal pieces and divide them among the 4 people</u>, making sure that each person gets an equal 9 pieces.
Step-by-step explanation:
9 pieces of licorice cut equally into 4 smaller bits then distributed throughout 4 people would play as this.
9x4=36
36/4 = 9
Each person would get 9 smaller pieces of licorice
Answer:
a. Mean = 6
Variance = 2.4
Standard Deviation = 1.55
b. P(X=16) = 0.124
Step-by-step explanation:
Given
n = Total shots = 10
p = Probability of success = 60%
p = 60/100
p= 0.6
q = Probability of failure
q = 1-p
q = 1 - 0.6
q = 0.4
a.
Mean = np
Mean = 10 * 0.6
Mean = 6
Variance = npq
Variance = 10 * 0.6 * 0.4
Variance = 2.4
Standard Deviation = √Variance
Standard Deviation = √2.4
Standard Deviation = 1.549193338482966
Standard Deviation = 1.55 --------- approximated
b.
We have X = 16
x = 10
Assume that the events "success" on the various throws are independent.
The 10th success came on the 16th attempt
So, the player had exactly 10 successes and 6 failures on 16th trial
So Probability = nCr 0.6^10 * 0.4^6
Where n = 15 and r = 9 (number of attempts and success before the 16th trial)
15C9 * 0.6^10 * 0.4^6
= 5005 * 0.0060466176 * 0.004096
= 0.123958563176448
= 0.124 ------ Approximated
Answer: The area is 64
Step-by-step explanation:
It’s 64 because when you divide the volume 480ft by the height 7.5ft you get the area as 64ft.
