Rafael writes an expression to represent “a number, n, decreased by thirty-one.” Then he evaluates that expression if n = 29. Which statements are true about the expression and its evaluation? Check all that apply.
The correct expression is 31 minus n.
This is a subtraction expression.
This is an addition expression.
To evaluate, substitute 29 for the variable in the expression.
To evaluate, substitute 31 for the variable in the equation.
To evaluate the expression, add 31 to 29.
The correct expression is n minus 31.
To evaluate the expression, subtract 31 from 29.

Answer:
The correct alternatives
This is a subtraction expression
The correct expression is n minus 31
To evaluate the expression, subtract 31 from 29.
Step-by-step explanation:
Rafael writes an expression to represent “a number, n, decreased by thirty-one.”
First you gotta know what means "decreased by thirty-one". It means that
there exist two numbers where the difference between them is 31.
The number [tex]n[/tex] decreased by 31 can be writen as
[tex]n-31[/tex]
The expression is therefore
[tex]n-x=31 \implies \boxed{x=n-31}, n, m \in \mathbb{R}[/tex]
Rafael evaluates the expression [tex](n-31)[/tex] for [tex]n=29[/tex]
[tex]n-31 = 29-31 = -2[/tex]

Solve the equation for all values of x in simplest form (x + 3)^2 = -16
Answers
Answer:
x = -7 or x = 1
Step-by-step explanation:
Given expression:
(x + 3)² = -16
Problem;
Solve for x;
Solution:
To solve for x; we use the factorization method;
Take -16 to the left of the equation;
(x + 3)² = -16
(x + 3)² + 16 = 0
(x+ 3)² + 4² = 0
if x² + y² = (x + y)(x - y)
So;
(x + 3 + 4) (x + 3 - 4) = 0
(x + 7)(x - 1) = 0
x + 7 = 0 or x - 1 = 0
x = -7 or x = 1
can you please help me solve this 1/3(x+6)=1/2(x-3)
Answers
Answer:
The answer is X=21
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
Simplify 1/3 and 1/2
It would look like [tex]\frac{(x+6)}{3} -\frac{(x-3)}{2}[/tex]
then[tex]\frac{21-x}{6}=0[/tex]
then mutiply 6 to each side and it will look like 21-x = 0
Last, subtract 21 from each side and it will be
21=x
which list shows the triangles in order from greatest area to least area
Answers
Answer:
H - Triangle Z, Triangle X, Triangle Y
Step-by-step explanation:
Triangle X area = rad(66.5) cm^3 ≈ 8.155cm^3
Triangle Y area = 8.15cm^3
Triangle Z area = (17.5/2)cm^3 = 8.75cm^3
8.75cm^3 > 8.155cm^3 > 8.15cm^3
Therefore:
Triangle Z area > Triangle X area > Triangle Y area
You need to borrow money for gas, so you ask your mother and your sister. You can only borrow money from one of them. Before giving you money, they each say they will make you play a game. Your sister says she wants you to flip a fair coin. She will give you $9 for heads and $21 for tails. Your mother says she wants you to roll a six-sided die. She will give you $5 times the number that appears on the die. Determine the expected value of each game and decide which offer you should take.
Answers
$105 for the dice game.
- > heads = $9
-> tails = $21
^ $9+$21=$30
dice game-
6 sides of a dice, she doubles it by 5.
1*5 + 2*5 + 3*5 + 4*5 + 5*5 + 6*5
^ 5+10+15+20+25+30= 105.
-> $105 for dice game.
you can easily get $9/$21 from your sister, but it won’t be as much from the dice, but you have more risk going with the dice since there’s 6 sides. the highest to get from your mother is $30 and the highest from your sister is $21, but the dice is the better deal.
The maximum amount you can get from your mother is $30, while the most amount you can get from your sister is $21, but the dice is the better bargain.
How to find that a given condition can be modeled by binomial distribution?Binomial distributions consist of n independent Bernoulli trials.
Bernoulli trials are those trials that end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))
Suppose we have random variable X pertaining to a binomial distribution with parameters n and p, then it is written as
[tex]X \sim B(n,p)[/tex]
The probability that out of n trials, there'd be x successes is given by
[tex]P(X =x) = \: ^nC_xp^x(1-p)^{n-x}[/tex]
The expected value of X is:
[tex]E(X) = np\\[/tex]

Your mother says she wants you to roll a six-sided die.

The expected value for a coin will be

The expected value for a dice will be
[tex]E(X) = 1 \times \dfrac{1}{6} = 0.1667[/tex]
You can easily receive $9/$21 from your sister, but it won't be as much as the dice, and you'll take a bigger risk with the dice because it has six sides.

Answers
Answer:
C. A loan finances the total purchase price of the car while a lease finances only the depreciated value and related fees
Step-by-step explanation:
He legit said it. (Just writing this for those who are blind)
One difference between obtaining a car with a lease or a loan is that: a loan finances the total purchase price of the car while a lease finances only the depreciated value and related fees.
What is the difference between a Loan and a Lease?A loan is suitable for a property that you wish to possess at the maturity date, i.e. anything with long-term worth.
On the other hand, a lease is ideal for items that deteriorate gradually and will not retain their worth beyond the period.
The most significant contrast between a lease and a loan is the manner in which the finance costs are paid.The interest on a loan is amortized throughout the period. i.e. your consumer pays more interest at the start and more principal in the end.
Although leasing is not free, the financing charges are predetermined all through the period and are not deducted from the borrowed amount.
From the information given:
One difference between obtaining a car with a lease or a loan is that: a loan finances the total purchase price of the car while a lease finances only the depreciated value and related fees.

Suppose that you are interested in estimating the average impact a job training program has on wages. After controlling for observed factors that influence wages, participation in the training program, you find that the coefficient for the training is 0.55 and the standard error is 1.06. Thus, we can infer that the training program has a positive and statistically significant impact on wages at a 95% confidence level.
a) true
b) false
Answers
Answer:
False
Step-by-step explanation:
From the question we are told that
The coefficient for the training is [tex]r = 0.55[/tex]
The standard error is [tex]SE = 1.06[/tex]
The confidence level is 95%
Generally the level of significant is mathematically represented as
[tex]\alpha =( 100 -95)\%[/tex]
=> [tex]\alpha = 0.05 [/tex]
Generally the critical value of [tex]\alpha = 0.05 [/tex] obtained from the normal distribution table is [tex]Z_{0.05} = 1.645[/tex]
Generally the test statistics is mathematically represented as
[tex]t = \frac{r }{SE}[/tex]
=> [tex]t = \frac{0.55}{1.06}[/tex]
=> [tex]t = 0.5189 [/tex]
Generally given that the [tex]t < Z_{\alpha }[/tex]
Hence there is no sufficient evidence to conclude that the program has a positive and statistically significant impact on wages at a 95% confidence level.

You move right 2 units and left 10 units. You end at (-5, -1). Where did you start?
Answers
Answer:
(-13,-1)
Step-by-step explanation:
Moving right means moving positively on the x-axis
Moving left means moving negatively on the x-axis
Follow the equation backwards using the x-coordinate:
Move left 10 units-- -5-10 = -15
Move right 2 units-- -15+2 = -13
Since the y-coordinate did not change, the point you started at is (-13,-1)

. Where does the line y = 3x + 5 cross the y-axis?
Answers
Answer: at 5
Step-by-step explanation: the 3 is the slope and the 5 is the y intercept. The y-intercept corresponds to the value of 5 when the x value is equal to 0
Based on what we know about the formula of a straight line, the line above would cross the y-axis at 5.
The formula for a straight line takes the form:
y = mx + c
m = Gradient
c = y-intercept
The line described takes the form of y = 3x + 5.
5 is therefore c in the formula of a straight line so we can infer that it is the point where the y-axis is crossed.
In conclusion, the y-axis is crossed at 5.
