Answer:
x = 8
Step-by-step explanation:
The measures of the angles in a triangle add up to equal 180°
That being said we can create an equation to solve for x
( note that this is a right triangle indicated by the square. A right triangle has a right angle which has a measure of 90° )
180 = 90 + 5x + 5 + 5x + 5
now we solve for x using basic algebra
step 1 combine like terms
90 + 5 + 5 = 100
5x + 5x = 10
now we have 180 = 100 + 10x
step 2 subtract 100 from each side
180 - 100 = 80
100 - 100 cancels out
now we have 10x = 80
step 3 divide each side by 10
10x / 10 = x
80 / 10 = 8
we're left with x = 8

The correlation coefficient between two quantitative variables is approximately 0.02. What does the value of this correlation coefficient indicate about how well the model
fits the data?
O A. The correlation coefficient is not within the correct range.
O B. The model is a good fit.
OC. No conclusion can be drawn regarding how well the model fits the data.
The model is not a good fit.
Answers
Answer:
The model is not a good fit
Step-by-step explanation:
The correlation Coefficient is a metric used to evaluate the strength of the relationship between 2 variables, the correlation Coefficient ranges from - 1 to + 1 with values closer to either ±1 depicting the strongwr and better relationship. A value of 0 means no relationship exists and values close to zero means the relationship is weak. Wutb a correlation Coefficient value of 0.02, this value is very close to 0 and hence shows that the relationahip is extremely weak. Hence, the model is not a good fit.

If $1205 is borrowed for 11 years at an annual simple insterest rate of 11.3%, what is the total amount that must be repaid rounded to the nearest cent?
Answers
Answer:
If the interest is yearly $2702.87 will be owed
Step-by-step explanation:
first you would need to find out how much 11.3% of $1205 is which is $136.17. And since the interest is yearly you would multiply the $136.17 by the 11 years which would be $1497.87. Then you would add the amount that they borrowed to the interest that they would owe after 11 years which would be $1497.87 + $1205 = $2702.87. So after 11 years the total amount that must be repaid is $2702.87

As you see, 2/10 = 8/40
2/4 = x/40, multiply by 10
2/4 = 20/40
Then add because same denominator
Now you would get:
8/40 + 20/40 = 28/40
Answer:
8/40 + 20/40 = 28/40
Step-by-step explanation:
It's about finding the common denominator for the fractions.
we can easily see that 40 is a common denominator for denominators 10 and 4. 20 would work too, but 40 is "instantly seen".
2/10 = (2*4) / (10*4) = 8/40
2/4 = (2*10) / (4*10) = 20/40
8/40 + 20/40 = (8+20) / 40 = 28/40

Answers
Answer:
Step-by-step explanation:
Convert each number to its decimal equivalent for easier comparison with the other numbers:
1/8 = 0.125 1 (smallest)
2/4 = 0.50 3
8/4 = 2.0 4
3/15 = 0.20 2
2 2/7 = 2.28 6 (largest)
20/10 = 2.00 5 (next to largest)
The smallest number is 1/8 (see above), and the largest is 2.28 (2 2/7).

Answers
Answer:
Linear
Step-by-step explanation:
The type of function which is represented in the table is quadratic, the correct option is B.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
Linear function is a function whose graph is a straight line
We are given that;
The table
Now,
Looking at the table, we can see that each input value is paired with only one output value, so the relationship is a function. We can also see that the difference between the output values is not constant, so the function is not linear. The quotient of the output values is not constant either, so the function is not exponential. The quotient of the output values does not change in a predictable way, so the function is not logarithmic.
Therefore, by the function the answer will be quadratic.

There are two labeled weights of 4 grams and 12 grams the tree circles have the same weight what is the weight of each circle in grams
Answers
Answer:
The answer is below
Step-by-step explanation:
Let x represent the unknown weight of each of the circles, since there are three of those type of circles, hence the unknown weight is 3x.
From the diagram, the sum of the total weight at one side must be equal to the sum of the total weight at the other side so that they can be balanced, hence:
3x + 4 = 12
subtracting 4 from both sides:
3x + 4 - 4 = 12 - 4
3x = 8
Dividing through by 3:
3x/3 = 8/3
x = 8/3
The weight of each of the circle is 8/3 grams

NEED HELP ASAP!The maker of a cell phone screen protector would like to estimate the proportion of customers who file a warranty claim. To do so, they select a random sample of 200 customers and determine that the 96% confidence interval for the true proportion of customers who file a warranty claim to be 0.15 to 0.28. Which of the following can be accounted for by the margin of error of this interval?
response bias
nonresponse bias
sampling variation
undercoverage bias
Answers
Answer: sampling variation
Step-by-step explanation: took the quiz
The margin of error is given by the sampling variation of the proportion of customers
What is simple random sampling ( SRS )?The most accurate type of probability sampling is random sampling. Each person in a population has an equal probability of getting selected for the sample thanks to this method of sampling.
This kind of sampling is perfect for highly controlled investigations where it is unacceptable to have human bias in the selection of the sample.
Each sampling unit in a population has an equal probability of being included in the sample when using simple random sampling (SRS). As a result, each potential sample has an equal probability of being chosen.
Given data ,
Let the margin of error be represented as A
where the value of A is
The confident interval is = 96 %
And , the value of sample is of 200 customers
where the warranty claims from 0.15 to 0.28
So , the cell phone screen protector maker can be 96% confident that the interval from 0.15 to 0.28 captures true proportion of customers who file a warranty claim
Therefore , it is a sampling variation
Hence , the situation is a sample variation
