Answer:
38°.
Step-by-step explanation:
A triangle adds up to 180°.
CAB= 78°
But we minus 78° from 46°:
32°.
As a triangle adds up to 180°,
110+32= 142°.
180-142= 38°.
To see if we are correct:
38+32+110= 180°.

Epidemiologic studies are of significant value to scientists who use the information from these studies to formulate dose-response estimates to predict the risk of various health outcomes or diseases.
By analyzing data on exposure levels and corresponding health effects in a population, researchers can establish the relationship between the dose (amount of exposure) and the response (risk or occurrence of the outcome). This allows them to estimate the potential risks associated with different levels of exposure to specific factors such as environmental pollutants, medications, lifestyle choices, or occupational hazards. These dose-response estimates help inform public health interventions, risk assessments, and policy-making decisions aimed at minimizing the occurrence and impact of health risks in populations.

a spinner is divided into 4 equal-size sections. the 4 sections are colored red, green, orange, and blue. if you spin the spinner once, what is the theoretical probability that you will spin green?
The theoretical probability of spinning green on the spinner, divided into 4 equal-size sections colored red, green, orange, and blue, is ¼ or 25%.
In this scenario, the spinner has four equal-size sections. Since each section is of equal size, the probability of landing on any specific section is the same. Therefore, the probability of spinning green, which is one out of the four possible outcomes, is 1/4 or 25%.
To calculate the theoretical probability, we divide the favorable outcomes (spinning green) by the total possible outcomes. In this case, there is one favorable outcome (green) out of four possible outcomes (red, green, orange, and blue), resulting in a probability of 1/4 or 25%.
It's important to note that theoretical probability is based on the assumption of equally likely outcomes and assumes a large number of trials. In practice, actual outcomes may deviate from theoretical probabilities due to factors like imbalances in the spinner or inherent randomness.

Step-by-step explanation:
use calculator to find both the compound amount and the interest on $7000 at 12% for 2 years. Interest is compounded quarterly. what is compound amount? round to the nearest cent as needed what is the Interest? Round to the nearest cent as needed
Compound amount = $8867.39
compound interest = $1867.39
EXPLANATION
Given:
Principal(p) = $7000 Rate(r) = 0.12 Time(t) = 2 n= 4
We can calculate the compound amount(A) using the formula below:
\(A=P(1+\frac{r}{n})^{nt}\)Substitute the values and evaluate.
\(A=7000(1+\frac{0.12}{4})^{4\times2}\)\(=7000(1+0.03)^8\)\(=7000(1.03)^8\)\(\approx8867.39\)Hence, the compound amount = $8867.39
We proceed to find the compound interest.
A = P + I
⇒ I = A - P
= 8867.39 - 7000
=1867. 39
Therefore, the compound interest = $1867.39

Rob ay all number have an even number of factor. Enrique ay ome number have an odd number of factor. Who i correct?
Marcia states that some numbers have an odd number of factors so Marcia is correct
Factors
A factor is a number that divides another number, leaving no remainder. In other words, if multiplying two whole numbers gives us a product, then the numbers are multiplying are factors of the product because they are divisible by the product. There are two methods of finding factors multiplication and division.
Odd Number and Even Number
Odd numbers are those numbers that cannot be divided into two equal parts, whereas even numbers are those numbers that can be divided into two equal parts. Examples of odd numbers are 3, 5, 7, 9, 11, 13, 15 Examples of even numbers are 2, 4, 6, 8, 10, 12, 14
Rob states that all numbers have an even number of factors.
Marcia states that some numbers have an odd number of factors.
Consider the number 36. It is given that,
1 × 36 = 36
2 × 18 = 36
3 × 12 = 36
4 × 9 = 36
6 × 6 = 36
The repeated factor is counted only once. So, the factors of 36 are given by 1, 2, 3, 4, 6, 9, 12, 18, and 36.
This tells us that 36 has 9 factors and has an odd number of factor. Then Marcia is correct

Marbeya scored a 90% on the last exam; the class average was 70% with a standard deviation of 15%. Based on this, what do you know about Marbeya's z score
Marbeya's z score when she scored a 90% on the last exam is 1.33.
Z scoreZ score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
\(z=\frac{x-\mu}{\sigma}\)
Where x is the raw score, μ is the mean and σ is the standard deviation.
Given that μ = 70% = 0.7, σ = 15% = 0.15
For x = 90% = 0.9:
z = (0.9 - 0.7)/0.15 = 1.33

Answer:
80
Step-by-step explanation:
Plot the data and find a line of best fit.
The line will have an equation in the form y = mx + b, where m is the slope of the line and b is the y-intercept.
To find a line of best fit, you would typically use a technique called linear regression. Linear regression involves fitting a straight line to the data that minimizes the overall distance between the line and the data points.
This line represents the best linear approximation of the relationship between the variables. To perform linear regression, you would need a set of data points that represent the relationship between two variables.
You can then use statistical software or tools like Excel to calculate the line of best fit. The line will have an equation in the form y = mx + b, where m is the slope of the line and b is the y-intercept.
Once you have the equation of the line, you can use it to make predictions or estimate values based on the given data.
It is important to note that the line of best fit may not pass through all the data points but rather represents the overall trend or relationship between the variables. It is also crucial to consider the assumptions and limitations of linear regression when interpreting the results.

if the sides of a square are lengthened by 3 m, the area becomes 81 m. find the original side length
The value of the original side length is, 6 m
Here, We have to given that;
All the sides of a square have lengthened by,
⇒ 3 m
And, the area of a square becomes,
⇒ 81 m²
Since, We know that;
A square is a two dimension figure with 4 equal sides, 4 corners and 4 right angles. The sides of the square are equal and parallel to each other.
Now, We can assume that,
the original side length is,
⇒ x
Hence, We can formulate by given condition,
⇒ (x + 3)² = 81
Taking square root both side,
⇒ x + 3 = √81
⇒ x + 3 = 9
Subtract 3 both side,
⇒ x = 9 - 3
⇒ x = 6 m
Therefore, We get;

In a short sentences please, Prove that the sum of two rational numbers is rational. THANK YOU!!!
The sum of two rational numbers is rational because the sum of any two fractions with rational numerators and denominators can be expressed as a fraction with a rational numerator and denominator.
How does this work?A rational number is any number that can be expressed as a ratio of two integers, where the denominator is not equal to zero. For example, 1/2, -3/4, 6/5, and 0 are all rational numbers.
When we add two rational numbers together, we can use the following formula:
a/b + c/d = (ad + bc) / bd
where a, b, c, and d are integers and b and d are not equal to zero.
This formula tells us that the sum of two rational numbers is also a rational number. The numerator of the sum is found by cross-multiplying the fractions, and the denominator of the sum is found by multiplying the denominators.
For example, if we want to add 1/2 and 2/3 together, we can use the formula above:
1/2 + 2/3 = (1 x 3 + 2 x 2) / (2 x 3) = 7/6
Therefore, the sum of 1/2 and 2/3 is 7/6, which is also a rational number. This formula can be used to prove that the sum of any two rational numbers is also a rational number.

A rational number is a number that can be written as \(\dfrac{a}{b}\) where \(a,b\in\mathbb{Z}\) and \(b\not=0\).
If one number is \(\dfrac{a}{b}\) and the other is \(\dfrac{c}{d}\), where \(b,d\not=0\), their sum is \(\dfrac{a}{b}+\dfrac{c}{d}=\dfrac{ad+bc}{bd}\). Since the set of integers is closed under addition and multiplication, we can write that \(\dfrac{ad+bc}{bd}=\dfrac{e}{f}\) where \(e,f\in\mathbb{Z}\) and \(f\not=0\), thus proving the sum of two rational numbers is a rational number.

Water makes up about 60% of the average adult's body weight. Represent this percent by shading in the squares.
Answer:
shading three boxes
Step-by-step explanation:
It is given that :
The body weight of an average adult = 60%
We have to show this by shading the square boxes shown.
There are 5 square boxes in total which makes up 100%.
So divide 100 by 5, we can 20% for each box.
So, 20% + 20% + 20% will give us 60%
Therefore, shading three boxes will give us 60% which is the water percent in an average adult's body weight.
This is represented by the figure below.
