Select the correct augmented matrices. Liam wants to buy a car and pay for it in three installments. The total cost of the car i

s $29,000. Two times the first installment is $1,000 more than the sum of the third installment and three times the second installment. Liam must pay 15% interest on the second and the third installments: the interest will amount to $2,100. If x, y, and z represent the first, second, and third installments, respectively, identify the augmented matrices that model Liam's situation.

Given: The car's total expense is 29,000 dollars, payable in three parts, labeled x, y, and z. Objective: Determine the values of x, y, and z. It's established that double the first installment equals $1,000 more than the total of the third installment alongside three times the second installment. This leads to the equation: 2x = $1,000 + z + 3y. By rearranging: z = 2x - 3y - 1,000. We also have the equation x + y + z = $29,000 + $2,100 or x + y + z = $31,100. From this point, we simplify and proceed to solve for x, y, and z step by step.

"The difference between five-halves of a number<br> and 17 is 48."
Inessa [12570]
Let the number be x. The equation x/5 - 17 = 48 leads to (x - 85)/5 = 48. Multiplying gives x - 85 = 240, so x = 240 + 85, resulting in x = 325.

Rachel found this rate of change for the scenario represented in the table.
babunello [11817]
THE FUNCTION IS CONTINUOUS - True
The table indicates that for every hour indicated, there is a corresponding amount of juice (cups) provided. The graph would represent a linear progression between the hours of 4 and 8 without any discontinuities.

TIME IS THE DEPENDENT VARIABLE - False
Time acts as the independent variable since it remains unaffected by any other factors. Conversely, the number of cups is contingent upon the hours, categorizing it as a dependent variable.

THE SCENARIO IS CHARACTERIZED BY
A LINEAR FUNCTION AS THE RATE OF CHANGE IS CONSTANT - True
The rate of change is a steady 53 cups per hour, indicating a linear function.

AS TIME INCREASES, THERE ARE FEWER CUPS OF JUICE POURED EACH HOUR - False
Since the rate of change is positive, the cups poured each hour will actually increase.

FOR EACH EXTRA HOUR, 53 CUPS OF JUICE ARE POURED - True
The hourly difference in cups poured is consistently 53.

A house cleaning service claims that it can clean a four bedroom house in less than 2 hours. A sample of n = 16 houses is taken
Zina [12379]

Response:

Option B is correct

Step-by-step breakdown:

H_0: x bar =2\\H_a: x bar

(One-tailed test at a significance level of 5%)

n = 16 and x̄ = 1.97

s = 0.1

Standard error of the mean = \frac{s}{\sqrt{n} } \\=0.025

Difference in means = 1.97-2 =-0.03

t statistic = Difference in means/se = -1.2

degrees of freedom = 16 - 1 = 15

p-value = 0.124375

(B) do not reject the null hypothesis since the test statistic (-1.2) is > the critical value (-1.7531).
