Answer: The required value is
[tex](f-g)(x)=x^2+8.[/tex]
Step-by-step explanation: The given functions are:
[tex]f(x)=2x^2+1,\\\\g(x)=x^2-7.[/tex]
We are given to find the value of [tex](f-g)(x).[/tex]
We know that, if s(x) and t(x) are any two functions of a variable x, then we have
[tex](s-t)(x)=s(x)-t(x).[/tex]
Therefore, we have
[tex](f-g)(x)\\\\=f(x)-g(x)\\\\=(2x^2+1)-(x^2-7)\\\\=2x^2+1-x^2+7\\\\=x^2+8.[/tex]
Thus, the required value is
[tex](f-g)(x)=x^2+8.[/tex]

Find the measure of the angle and please explain step by step
angle 4 is the same as angle 8
angle 7 & angle 8 has to equal 180 degree
so angle 7 and angle 4 also have to equal 180
angle 4 is 3 times the size of 7
lets call 7 (x)
so 4(x) = 180
180/4 =45
x=45
angle 7 is 45 degrees

If cba represents three numbers multiplied together, what property allows you to rearrange the factors to read abc?
The commutative property allows you to rearrange the factors of a multiplication problem.
Explanation:The property that allows you to rearrange the factors of a multiplication problem is the commutative property. This property states that the order of the factors can be changed without changing the product. In this case, if cba represents three numbers multiplied together, you can rearrange the factors to read abc because multiplying in any order will give you the same product.
For example, if c = 2, b = 3, and a = 4, then cba = 2 * 3 * 4 = 24. Rearranging the factors to abc gives abc = 4 * 3 * 2 = 24, which is the same product.

Estimate then find the product 7×7956
Final answer:
To estimate the product of 7 and 7956, round 7956 to 8000 and then multiply by 7 to get 56,000. The exact product, calculated using the multiplication algorithm, is 55,692.
Explanation:
To estimate the product of 7×7956, we can round 7956 to the nearest thousand which gives us 8000. Then, we multiply 7×8000 to get an estimated product of 56,000. To find the exact product, we multiply 7 by 7956 to get 55,692.
When calculating such a product, we use the multiplication algorithm where we multiply each digit of the second number by the first number and then add up the resulting values.
Here's how you would perform the multiplication step by step:
7×7 = 49, add the carried over 6 to get 55, write down 5 and carry over the 5.
After placing the digits in their correct positions, we get the final answer: 55,692. Therefore, the exact product of 7×7956 is 55,692.

the formula I=square root w/r gives the electric current I amperes that flows through an appliance, where W is the power in watts and R is the resistance in ohms. which set of numbers best describes the value of I for the given values of W and R? ( 42.) W=100,R=25 ( 43.)W=100,R=50
Final answer:
The value of I for the given values of W and R can be calculated using the formula I = [tex]\sqrt{(W/R)[/tex]. For W = 100 and R = 25, the value of I is 2 amperes. For W = 100 and R = 50, the value of I is approximately 1.41 amperes.
Explanation:
The formula I = [tex]\sqrt{(W/R)[/tex] gives the electric current in amperes that flows through an appliance, where W is the power in watts and R is the resistance in ohms.
To determine the value of I for the given values of W and R, we can simply substitute the values into the formula. For the first set of numbers, W = 100 and R = 25:
[tex]I = \sqrt{(100/25)} = \sqrt{(4)} = 2[/tex] amperes.
For the second set of numbers, W = 100 and R = 50:
[tex]I = \sqrt{(100/50)} = \sqrt{(2) }[/tex]≈ 1.41 amperes.
Therefore, the value of I for the first set of numbers (W = 100, R = 25) is 2 amperes, and the value of I for the second set of numbers (W = 100, R = 50) is approximately 1.41 amperes.

Linear regression describes the extent to which _______ predicts ________.
Linear regression describes the extent to which an independent variable predicts a dependent variable through a linear relationship.
Explanation:Linear regression describes the extent to which an independent variable (x) predicts a dependent variable (y) through a linear relationship.
For example, if we have data that shows the number of hours studied (x) and the test score (y) of students, linear regression can help us determine how well the number of hours studied predicts the test score.
The regression line is used to model the linear relationship between the independent and dependent variables in the population.

For a standard normal distribution, the probability of obtaining a z value between -1.9 to 1.7 is
P(X≤−1.9)=0.0287165598160018P(X≤−1.9)=0.0287165598160018
P(X≥1.7)=0.044565462758543P(X≥1.7)=0.044565462758543
P(−1.95996398454005≤X≤1.95996398454005)=0.95
Answer:
92.67% probability of obtaining a z value between -1.9 to 1.7.
Step-by-step explanation:
Normal probability distribution
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
For a standard normal distribution, the probability of obtaining a z value between -1.9 to 1.7 is
This probability is the pvalue of z = 1.7 subtracted by the pvalue of z = -1.9.
z = 1.7 has a pvalue of 0.9554.
z = -1.9 has a pvalue of 0.0287.
So there is a 0.9554-0.0287 = 0.9267 = 92.67% probability of obtaining a z value between -1.9 to 1.7.

box contains 15 items,4 of which are defective and 11 are good. Two items are selected. What is probability that the first is good and the second defective?
Final answer:
The probability that the first item selected is good and the second item is defective is 22/105.
Explanation:
To find the probability that the first item selected is good and the second item is defective, we need to consider the total number of items, the number of good items, and the number of defective items.
The total number of items is 15, with 11 being good and 4 being defective. When we select the first item, there are 15 options, out of which 11 are good. Therefore, the probability of selecting a good item first is 11/15.
After selecting the first item, there are now 14 items left in the box, with 10 being good and 4 being defective. When we select the second item, there are 14 options, out of which 4 are defective. Therefore, the probability of selecting a defective item second is 4/14, which simplifies to 2/7.
To find the probability that both events occur, we multiply the probabilities: (11/15) * (2/7) = 22/105.
