The slope of a linear function of the table of values given above is calculated as: m = 3.

The slope of a linear function is calculated as change in y over change in x. Note that f(x) is also the same as variable "y".

To calculate the slope, pick any two pairs of values from the table given, i.e. (2, 3) and (3, 6):

Slope of the linear function (m) = change in y / change in x = 6 - 3 / 3 - 2

Slope (m) = 3/1

Slope (m) = 3.

Answer: C. 96

Step-by-step explanation:

I took 8×3×4=96

Since the height is 5 in and it already took up one inch, that means just 4 more inches to go hence the 4 in the multiplication.

The requried class average is 83.2 points.

To find the class average, we need to calculate the total number of points earned by all the students and divide by the total number of students.

The 12 students who scored 80 points earned a total of 12 × 80 = 960 points.

The 8 students who scored 88 points earned a total of 8 × 88 = 704 points.

The total number of points earned by all the students is 960 + 704 = 1664 points.

The total number of students is 12 + 8 = 20.

To find the class average, we divide the total number of points by the total number of students:

average = total points / total students

average = 1664 / 20

average = 83.2

Therefore, the class average is 83.2 points.

Answer:

A

Step-by-step explanation:

The opposite of an integer is the number on the opposite side of the number line with the same distance from zero. So, the integers that are opposites are 14 and -14, 17 and -17, 32 and -32, and 15 and -15. This is because these pairs have the same absolute value but different signs. For instance, the absolute value of 14 is 14, and the absolute value of -14 is also 14. Therefore, -14 is the opposite of 14. Similarly, -17 is the opposite of 17 and so on.

Answer:

215

Step-by-step explanation:

To solve this expression, we must first use the order of operations. We begin with the parentheses and evaluate 23-11, giving us 12. Then, we divide 48 by 12, which equals 4. Finally, we multiply 4 by 38, resulting in 152. We add this to 63, giving us a final answer of 215. Thus, the solution to 63+48÷(23-11)×38 is 215.

The mode is the number that appears most.

Answer: 7

Answer:

7

Step-by-step explanation:

The mode is the most frequently occurring value in a set of data. In this case, the number 7 occurs twice, which is more than any other number, so the mode is 7. It is worth noting that if there were no values that occurred more than once, then there would be no mode for the data set. In this case, the data set has a single mode, but it is possible for a data set to have multiple modes if there are multiple values that occur with the same highest frequency.

Using a standard normal distribution table or calculator, we can find the p-value associated with z = 4.39 to be less than 0.0001.

For test the claim that half of all teens have made new friends online, we can use a hypothesis test.

Null hypothesis:

The proportion of teens who have made new friends online is equal to 0.5.

Alternative hypothesis:

The proportion of teens who have made new friends online is not equal to 0.5.

We will use a one-sample proportion test with a significance level of 0.01.

For calculate the test statistic, we can use the formula:

z = (p - P₀) / sqrt(P₀ * (1 - P₀) / n)

where p is the sample proportion, P₀ is the hypothesized proportion (0.5), and n is the sample size.

Using the given information, we have:

p = 0.57

P₀ = 0.5

n = 1060

Plugging these values into the formula, we get:

z = (0.57 - 0.5) / sqrt(0.5 x 0.5 / 1060)

z = 4.39

Hence, Using a standard normal distribution table or calculator, we can find the p-value associated with z = 4.39 to be less than 0.0001.

Since the p-value is less than the significance level of 0.01, we reject the null hypothesis and conclude that there is sufficient evidence to suggest that more than half of all teens have made new friends online.

When about 60.2 liters of fuel are added to each car, the two vehicles will have the same mass.

Let x be the number of liters of fuel needed for the two vehicles to have the same mass.

The first vehicle's total mass with fuel is: 1295 + 0.737x

The total weight of the second vehicle with gasoline is: 1290 + 0.820x

We want the two masses to be equal so that we may equalize the two expressions and solve for x:

295 + 0.737x = 1290 + 0.820x

0.083x = 5

Wyatt paid 1.2422 times the amount of subtotal x, including tax and tip.

We have,

The amount of tax applied to the bill is 6% of the subtotal, or 0.06x.

The total bill (including tax) is.

x + 0.06x = 1.06x

To find the amount of tip Wyatt left on the total bill, we need to multiply the total bill by 17% (or 0.17):

0.17(1.06x) = 0.1802x

The expression in terms of xx that represents the total amount that Wyatt paid is:

= x + 0.06x + 0.1802x

Total amount = 1.2422x

The graph of f(x) = x(x+5)(x+3) / (x+3)(x+5) bears resemblance to the line y=x since both plots share similar linear characteristics.

Both the numerator and denominator of f(x) = x(x+5)(x+3) / (x+3)(x+5) cancel out the factors (x+3) and (x+5), giving us a simplified expression for the function, f(x) = x.

A line with a slope of 1 passes through the origin in an upward direction. When we examine the graph of y=x, which is a straight line passing through the origin with a slope of 1, it becomes apparent that adding 1 to x also adds 1 to y.

Since the simplified expression is merely f(x) = x, we can deduce that the graph of this function follows a linear path passing through the origin with a slope of 1.

In conclusion, the graph of f(x) = x(x+5)(x+3) / (x+3)(x+5) bears resemblance to the line y=x since both plots share similar linear characteristics.
