Answer:

Step-by-step explanation:
∠1 = ∠2
∠3 = ∠4
∠JKN = ∠1 + ∠2 = 8x + 2
∠MKN = ∠3
∠MKL = ∠4 = 3x + 5
So, ∠3 = 3x + 5

Answer:
D
Step-by-step explanation:
Exponential decay occurs when the base is less than 1 but greater than 0.
3/2 = 1.5 and is greater than 1.
-3/2 is not greater than 0 and is not exponential
-2/3 is not greater than 0 and is not exponential
2/3 is less than 1 and greater than 0. This is decay.
Answer: 8

Answer:
$392
Step-by-step explanation:
Given the expression :
Total cost = 20a + 13c
a = adult
c = student
The total cost for 4 adults and 24 students
a = 4 ; c = 24
Total cost :
20(4) + 13(24)
80 + 312
= $392
Answer:
At the 0.05 level of significance, the claim made by Blue Diamond is true
Step-by-step explanation:
Given that the Blue Diamond Company advertises that their nut mix contains (by weight) 40% cashews, 15% Brazil nuts, 20% almonds and only 25% peanuts.

(Two tailed chi square test at 5% significance level)
Chi square is calculated as (Obs_exp)^2/Expected
Cashews Brazil nuts Almonds Peanuts Total
Observed 5 6 6 3 20
Expected 40% 15% 20% 25% 1
Expected 8 3 4 5 20
Chi square 1.125 3 1 0.8 5.925
df = 3
p value = 0.1153
Since p value >0.0 we accept null hypothesis.
