what is the total if your tip is 20% and your subtotal is 7.47
Answers
Answer:
$8.96
Step-by-step explanation:
To find the total amount, multiply the percentage of the tip (20%) as 0.20 with 7.47
(7.47×0.20=1.494)
Add $1.49 to $7.47
(1.49+7.47=8.96)
And there is your total amount with a 20% tip!

The probability that more than one coin lands heads up is 0.9375.
What is a binomial distribution in probability?In an experiment with two possible outcomes, the likelihood of exactly x successes on n repeated trials is known as the binomial probability.
The binomial probability is [tex]^nC_xp^xq^{n-x}[/tex].
Given, Four fair coins are flipped and the number of heads that land face up are counted.
Let, 'p' be the probability of getting a head and 'q' be the probability of getting a tail,
So, p = 1/2 and q= 1/2.
Therefore, The probability that more than one coin lands heads up is,
P(X ≥ 1) = P(X = 1) + P(X = 2) + P(X = 3) + P(X = 3).
P(X ≥ 1) = [tex]^4C_1p^1q^3 + ^4C_2p^2q^2 + ^4C_3p^3q^1 + ^4C_4p^4q^0[/tex].
P(X ≥ 1) = [tex]^4C_1(1/2)^1(1/2)^3 + ^4C_2(1/2)^2(1/2)^2 + ^4C_3(1/2)^3(1/2)^1 + ^4C_4(1/2)^4(1/2)^0[/tex].
P(X ≥ 1) = 4(0.5×0.125) + 6(0.25×0.25) + 4(0.125×0.5) + 1(0.0625).
P(X ≥ 1) = 0.25 + 0.375 + 0.25 + 0.0625.
P(X ≥ 1) = 0.9375.
So, The probability of getting one or more heads is 0.9375.

Two dice are rolled. Find the probability of getting a. A sum of 5, 6, or 7 b. Doubles or a sum of 6 or 8 c. A sum greater than 8 or less than 3 d. Based on the answers to parts a, b, and c, which is least likely to occur
Answers
Answer:
The answer is below
Step-by-step explanation:
The possible outcome from rolling two dice is:
1,1 1,2 1,3 1,4 1,5 1,6
2,1 2,2 2,3 2,4 2,5 2,6
3,1 3,2 3,3 3,4 3,5 3,6
4,1 4,2 4,3 4,4 4,5 4,6
5,1 5,2 5,3 5,4 5,5 5,6
6,1 6,2 6,3 6,4 6,5 6,6
The total number of outcomes = 36
a)
P(sum of 5) = 4/36, P(sum of 6) = 5/36, P(sum of 7) = 6/36
Hence:
P(sum of 5 or sum of 6, or sum of 7) = P(sum of 5) + P(sum of 6) + P(sum of 7) = 4/36 + 5/36 + 6/36
P(sum of 5, 6, or 7) = 15 / 36
b)
P(doubles) = 6/36, P(sum of 6) = 5/36, P(sum of 8) = 5/36
Hence:
P(doubles or sum of 6 or sum of 8) = P(doubles) + P(sum of 6) + P(sum of 8) = 6/36 + 5/36 + 5/36
P(doubles or sum of 6 or sum of 8) = 16 / 36
c)
P(sum greater than 8) = 10/36, P(sum lesser than 3) = 1/36
P(sum greater than 8 or less than 3) = P(sum greater than 8) + P(sum lesser than 3) = 10/36 + 1/36
P(sum greater than 8 or less than 3) = 11 / 36
Part c has the least probability of occurrence, hence c is least likely to occur.

There is a difference between the percentage of volunteers selected from the college students.
Step-by-step explanation:
Step(i):-
Given that the Population proportion P= 12% = 0.12
Given that the 331 randomly selected students who receive financial aid, 43 of them volunteered their time.
Sample proportion
[tex]p = \frac{x}{n} = \frac{43}{331} = 0.1299[/tex]
Step(ii):-
Null Hypothesis:-H₀: P = 0.12
There is a difference between the percentage of volunteers selected from the college students.
Alternative Hypothesis:-H₁: P ≠ 0.12
There is no difference between the percentage of volunteers selected from the college students.
Step(iii):-
Test statistic
[tex]Z = \frac{p-P }{\sqrt{\frac{PQ}{n } } }[/tex]
[tex]Z = \frac{0.1299-0.12 }{\sqrt{\frac{(0.12)(0.88)}{331 } } }[/tex]
Z = 0.5543
Level of significance = 0.01
Critical value Z₀.₀₁ = 2.376

The graph for the given condition is attached below.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that, Tyler's cell phone plan costs $350 to start, then there is a $50 charge each month.
Suppose the number of months is x and the total amount is y, The obtained equation for the given condition is,
y=350+50x

Step-by-step explanation:
You need to distribute:
2(2x+9) = 5x + 72
4x + 18 = 72
Then subtract 18 from both sides of the equation. Step 2 dosnt do this.
