3. Over the weekend, Jada made three times as much money babysitting than Han did mowing lawns. Jada made an additional $27 selling lemonade. From babysitting and selling lemonade, she has a total of $96. If the equation 3x + 27 = 96 represents this situation, what does the variable x represent?
Answers
Answer:
X is the amount Han made mowing lawns
because it said that she earned 3xs the amount he did. So you would take what he made times three plus the extra 27 she made from selling lemonade

Which is the most accurate way to estimate 66% of 46?
A: 2/3 x 47
B: 1/3 x 45
C: 1/3 x 47
D: 2/3 x 45
Answers
Answer:
30 Don't use your calculator.
Step-by-step explanation:
This is an estimation question, so you have to throw your calculator out of your reach.
You have to know that 66% is nearly 2/3 So the correct answer cannot be B or C
It must be A or D.
The problem is that 3 doesn't go into 46 so you have to change it to something that is divisible by 3. Of the numbers given, the best one is 45
2/3 * 45 = 2 * 15 = 30
How close is that (remember you have to give 30 as your answer)?
The actual answer is 30.36 which makes your estimate very good.

Mr. And Mrs. Doran have a genetic history such that the probability that a child being born to them with a certain trait is 81%. If they have four children, what is the probability that exactly four of their four children will have that trait? Round your answer to the nearest thousandth.
Answers
Answer:
0.430 (nearest thousandth)
Step-by-step explanation:
Using binomial probability relation :
p = 0.81
n = 4
x = 4
1 - p = 1 - 0.81 = 0.19
Recall ;
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 4) = 4C4 * 0.81^4 * 0.19^(4-4)
P(x = 4) = 1 * 0.43046721 * 1
P(x = 4) = 0.43046721
P(x = 4) = 0.430 (nearest thousandth)
When adding polynomials, you combine like terms. Then put the polynomial in standard form. true or false
Answers
Answer:
True
Step-by-step explanation:
Polynomials are expressions containing one or more variables that are raised to powers beyond 2.
In standard form, a polynomial may be arranged based on the power of the variable. For example
X^3 + 2x^2 + 5
The above polynomial has been arranged in standard form. To add or subtract two polynomials, the two expressions are rearranged to combined like terms and then organized in standard form

how would you do log(3250) without a calculator
Answers
Answer:
Step-by-step explanation:
It depends on what level you are. Logs are most easily developed by using a series for the natural logarithms (instead of base 10, you use base e). Even that is a difficult process using a series that you won't be introduced to until your second calculus course..
For now, I'd be content to use a calculator. The series does not converge terribly quickly.
The probability that a student guesses the correct answer to a five-choice multiple choice question is P(correct)=0.2. How many correct answers should a student expect to guess on a test with 60 five-choice multiple choice questions?

x = 12 cm
Step-by-step explanation:
Based on the tangent and secant theorem,
8² = 4(4 + x)
Solve for x
64 = 16 + 4x
Subtract 16 from both sides
64 - 16 = 4x
48 = 4x
Divide both sides by 4
48/4 = 4x/4

If ∠1 and ∠2 are complementary angles, and m∠1 = 74°; find m∠2
Answers
Answer:
m∠2 = 16°
Step-by-step explanation:
m∠1 + m∠2 = 90°
(Complementary angles)
74° + m∠2 = 90°
m∠2 = 90° - 74°
m∠2 = 16°
The measure of the angles 2 is 16 degrees
How to find complementary anglescomplementary angles sum up to 90 degrees.
Given one of the angles to be 74 degrees, hence;
m<1 + m<2 = 90 degrees
74 + m<2 = 90
m<2 = 90 - 74
m<2 = 16 degrees
Hence the measure of the angles 2 is 16 degrees
