Answer:
Step-by-step explanation:
Given that
(3x) is raised to power 5
(3x)^5
Then,
Using indices
(AB)ⁿ = Aⁿ•Bⁿ
Then,
(3x)^5= 3^5•x^5
Then, 3^5 means=3×3×3×3×3=243
So,
(3x)^5= 243x^5
Answer: 0.5143
Step-by-step explanation:
Probability of students who are over 21 years old = 30% = 0.3
Probability of students who are under 21 years old = 100% - 30% = 70% = 0.7
Probability of drinking alcohol for over 21 = 80% = 0.8
Probability of not drinking alcohol for over 21 = 100%- 80% = 20% = 0.2
Let the probability of the students who are not over 21, that drink alcohol be p.
Total probability of a college student drinking alcohol = (0.3 × 0.8) + (0.7 × p)
0.6 = (0.3 × 0.8) + (0.7 × p)
0.6 = 0.24 + 0.7p
0.7p = 0.6 - 0.24
0.7p = 0.36
p = 0.36/0.7
p = 0.5143
The probability of the students who are not over 21, that drink alcohol is 0.5143.
Answer:
I have this same question do you have the answer??
Step-by-step explanation:
Answer:
? = 8a
The other blank textbox = 35
Step-by-step explanation:
You are using the distributive property which means multiplying the number in front of the parentheses to the equation within the parentheses.
The number in-front is '8' for this equation.
The equation within the parentheses is ( a + 5 )
8 ( a + 5 )
You multiply the 8 to the equation in the parentheses.
8 * a
8 * 5
8 * a = 8a
8 * 5 = 40
So,
? = 8
The other blank equals 40
Answer: The answer is 14
Step-by-step explanation:
For 2.5 they multiplied by 10 so you'd do that for 1.4 and the answer would be 14
