Answer:

As the calculated z does not fall in the critical region we fail to reject H0 and conclude that there is sufficient evidence that the average past-due amount for customers who have been called previously about their bills is now no larger than $23.

Step-by-step explanation:

As the standard deviation for the past due amounts is 63

The sample size n= 67

1) Formulate the null and alternate hypothesis

H0: u ≤ 23 against the claim Ha: u > 23

2)  The test statistics is

Z= x- u / σ/ √n

z= 20- 23/ 63/ √67

z= 0.00581

z= 0.006

3) The significance level ∝= 0.1

4) The critical value for ∝= 0.1 is Z > ±2.33

5) As the calculated z does not fall in the critical region we fail to reject H0 and conclude that there is sufficient evidence that the average past-due amount for customers who have been called previously about their bills is now no larger than $23.

my guess it's 4

(x+7) (x-3)

The value of k for which f(x + 3) = x^2+kx-21 for the considered function f(x) is found to be k = 4

You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.

It is given that:

[tex]f(x) = x^2 -2x - 24[/tex]

and [tex]f(x+3) = x^2 + kx - 21[/tex]

Putting x = x+3 in the definition of f(x), we get:

[tex]f(x+3) = (x+3)^2 -2(x+3) -24\\\\f(x+3) = x^2 + 6x + 9 -2x -6 - 24\\\\f(x+3) = x^2 + 4x -21[/tex]

Comparing it with [tex]f(x+3) = x^2 + kx - 21[/tex], we see that k is having value as 4 for the considered function.

Thus, the value of k for which f(x + 3) = x^2+kx-21 for the considered function f(x) is found to be k = 4

Answer:

Mean = $54.67

Step-by-step explanation:

How to Find the Mean

Add up all data values to get the sum

Count the number of values in your data set

Divide the sum by the count

The mean is the same as the average value in a data set.

Mean Formula

The mean x of a data set is the sum of all the data divided by the count n.

mean=x¯¯¯=∑ni=1xin

Solve

Add up all data values to get the sum

$29 + $58 + $15 + $129 + $75 + $22 = $328

Count the number of values in your data set

$29 and $58 and $15 and $129 and $75 and $22 = 6

Divide the sum by the count

328 ÷ 6 = 54.6666666667

Nearest tenth = 54.67

Therefore, the Mean = $54.67

x1 = -4

x2 = 3

Step-by-step explanation:

[tex]x^{2} + x = 12\\x^{2} +x-12=0\\x^{2} +4x-3x-12=0\\x*(x+4)-3(x+4)=0\\(x+4)*(x-3)=0\\x+4= 0 \\x-3=0\\x=-4 \\x=3\\x1=-4 \\x2=3[/tex]

Step-by-step explanation:

=> x² + x = 12

=> x² + x -12 = 0

=> x² + 4x - 3x -12 = 0

=> x ( x + 4)-3(x + 4) = 0

=> ( x + 4)(x-3)=0

=> x = 3 , -4

Answer:

35 members

Step-by-step explanation:

In a tennis club the ratio number of junior members : number of senior members is 7 : 10

From the above ratio

Number of junior member = 7

Number of senior members = 10

There are 18 more senior members than junior members.

S = 18 + j

10 + 18 = 28 senior members

Hence,

Total number of members = 28 senior members + 7 junior members

= 35 members
