x = 5
Step-by-step explanation:
Answer:
n = 24
q = 8
Step-by-step explanation:
Let:
n = nickels
q = quarters
5n + 25q = 320
n + q = 32
n = 32 - q
Substitute (to solve for q):
5(32 - q) + 25q = 320
160 - 5q + 25q = 320
160 + 20q = 320
20q = 320 - 160
20q = 160
q = 160 ÷ 20
q = 8
Substitute (to solve for n):
n = 32 - q
n = 32 - (8)
n = 24
Answer:
a. 0.6899
b. 0.1642
Step-by-step explanation:
a. Given the probability of success is 0.94 for an expert and that the number of pairs, n=6:
-Each attempt is independent and therefore the probability of the events is calculated as:

Hence, the probability of correctly identifying the 6 matches is 0.6899
b.Given the probability of success is 0.74 for a novice and that the number of pairs, n=6:
-Each attempt is independent and therefore the probability of the events is calculated as:

#Hence, the probability of correctly identifying the 6 matches is 0.1642
*I have used the sample size of 6(due to conflicting info/question size).
Factor x+5 out of 3x (x+5)+4(x+5)
And you get (x+5)(3x+4)
Answer:
Impossible to tell as you have not informed us about f(x)
Step-by-step explanation:
In any case -f(x) will mirror f(x) over the x axis.
