Intervals
A numeric interval consists of a set of numbers (in case they are whole or integer numbers) or a range of numbers that fulfill a rule or condition.
We are given a graph where the interval (-∞,-2] can be identified. This means the numbers that are less or equal to -2 belong to the solution.
From the numbers given in the options, we should only select those who are less than or equal to 2:
A. -2
D. -4
E. -10
Options B and C are not correct because 0 and 5 don't lie on the solution interval
An exercise machine with an original price of $890 is on sale at 24% off.
a. What is the discount amount?
b. What is the exercise machines sale price?
The discount amount is $213.6
The sale price for the exercise machines is $676.4
How to calculate the discount amount ?The first step is to calculate the discount amount
890 × 24/100
= 890 × 0.24
= 213.6
The next step is to calculate the sale price
890(1-0.24)
890(0.76)
676.4
Hence the discount amount is $213.6 and the sale price of the exercise machine is $676.4

Originally the price is 849 the store offers a 20% discount and a 6% sales tax
The total cost of the computer is 719.95 if Originally the price is 849 the store offers a 20% discount and a 6% sales tax
What is Algebraic expression ?
Algebraic expression can be defined as combination of variables and constants.
To find the purchase total, multiply the price by the percent paid and add the percent of tax.
The store offers a 20% discount
This means you pay 80% of the price. So the discounted price is 0.80(849) = 679.2.
Find the tax to be paid by multiplying 0.06(679.2) = 40.752.
Add the tax for the final total.
679.2 + 40.752 = 719.95
Hence, The total cost of the computer is 719.95 if Originally the price is 849 the store offers a 20% discount and a 6% sales tax

Graph the point on the graph.
Answer:
see below
Step-by-step explanation:
To graph this equation, start at the origin (0,0) since there is not y-intercept.
Because slope is characterized by rise/run ( i.e. how many units up or down depending on whether it is positive or negative and then however many units to the right.
Because the rise (up and down, numerator) is 1, we know that we will go up one unit.
The run (side to side, denominator) is 4, so we will go to the right 4 units.
This makes the first point (4, 1).

What is mathematical expression?
Expression in math is defined as the collection of the numbers, variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is;
''The expression negative one eighth j plus two thirds minus the expression five thirds j plus nine twelfths.''
Now, We can write the expression in mathematical form as;
⇒ (- 1/8 j + 2/3) - (5/3 j + 9/12)
Solve the expression as;
⇒ - 1/8 j + 2/3 - 5/3 j - 9/12
⇒ - 1/8 j - 5/3 j + 2/3 - 9/12
⇒ j (-1/8 - 5/3) + 2/3 - 3/4
⇒ j (- 3 - 40)/24 + (8 - 9)/12
⇒ j (-43/24) + (- 1/12 )
This can be written as;
''negative 43 over 24 times j plus negative 1 over 12''
Therefore, The value of the expression after simplify will be,
''negative 43 over 24 times j plus negative 1 over 12.''
Option D is true.
2. The expression is given as;
3(−4.5b − 2.1) − (6b + 0.6)
Solve the expression as;
3(−4.5b − 2.1) − (6b + 0.6)
3 x -4.5b - 3 x 2.1 - 6b - 0.6
- 13.5b - 6.3 - 6b - 0.6
- 13.5b - 6b - 6.3 - 0.6
- 19.5b - 6.9
Thus, The expression is equivalent to 3(−4.5b − 2.1) − (6b + 0.6) will be;

2) The mean mathematics SAT score in 2012 was 514 with a standard deviation of 117 ("Total group profile," 2012). Assume the mathematics SAT score is normally distributed. a. State the random variable. b. Find the probability that a person has a mathematics SAT score over 700. c. Find the probability that a person has a mathematics SAT score of less than 400. d. Find the probability that a person has a mathematics SAT score between a 500 and a 650. e. Find the mathematics SAT score that represents the top 1% of all scores.
The mathematics SAT score representing the top 1% of all scores is approximately 780.
a. The random variable in this case is the mathematics SAT score.
b. To find the probability that a person has a mathematics SAT score over 700, we need to calculate the z-score first.
The z-score is calculated as \(\frac{(X - \mu )}{\sigma}\),
where X is the value we're interested in, μ is the mean, and σ is the standard deviation.
In this case, X = 700, μ = 514, σ = 117.
Using the formula, the z-score is \(\frac{(700 - 514)}{117 } = 1.59\).
To find the probability associated with this z-score, we can consult a standard normal distribution table or use a calculator.
The probability is approximately 0.0564 or 5.64%.
c. To find the probability that a person has a mathematics SAT score of less than 400, we again calculate the z-score using the same formula.
X = 400, μ = 514, and σ = 117.
The z-score is \(\frac{(400 - 514) }{117 } = -0.9744\).
Looking up the probability associated with this z-score, we find approximately 0.1635 or 16.35%.
d. To find the probability that a person has a mathematics SAT score between 500 and 650, we need to calculate the z-scores for both values.
Using the formula, the z-score for 500 is \(\frac{(500 - 514)}{117 } = -0.1197\),
and the z-score for 650 is \(\frac{(650 - 514)}{117 } = 1.1624\).
We can then find the area under the normal curve between these two z-scores using a standard normal distribution table or calculator.
Let's assume the probability is approximately 0.3967 or 39.67%.
e. To find the mathematics SAT score that represents the top 1% of all scores, we need to find the z-score corresponding to the top 1% of the standard normal distribution.
This z-score is approximately 2.33.
We can then use the z-score formula to calculate the corresponding SAT score.
Rearranging the formula,
\(X = (z \times \sigma ) + \mu\),
where X is the SAT score, z is the z-score, μ is the mean, and σ is the standard deviation.
Substituting the values,
\(X = (2.33 \times 117) + 514 = 779.61\).
Rounded to the nearest whole number, the mathematics SAT score representing the top 1% of all scores is approximately 780.

40 x 2.5 = 100
30 x 2.5 = 75
75/100 = 3/4

A researcher is exploring the notion that there is an economy of scale in raising children. While having one child might add to a family's financial stress, the second or third one might not be as "expensive" since they would already be sharing one roof, could share clothing, etc. The researcher has access to a large community of parents where 15% have one child under 18 in their home, 65% of parents have two children, and 20% of parents have three or more children. Rounded to the nearest whole number, the probability that any given family who is selected has two or more children at home is ________ %?
Answer:
The probability is \(G = 85% \)
Step-by-step explanation:
From the question we are told that
The percentage of parents that have one child under 18 in their homes is k = 15%
The percentage of parents that have two children is T = 65%
The percentage of parents that have three or more children is Y = 20%
Generally the probability that any given family who is selected have two or more children at home is mathematically evaluated as
\(G = T + Y\)
=> \(G = 65% + 20% \)
=> \(G = 85% \)
