Select the correct answer. What is the range of the function f(x) = -4\x+ 11 - 5? A. (-4,-5) B. [-5,-) OC. (-4,-) OD. (-2,-4] Re
Y_Kistochka [10]

We are given the following function:

f(x)=-4\lvert x+1\rvert-5

This function is equivalent to the function:

g(x)=-4\lvert x+1\rvert

Together with a translation 5 units in the negative direction of the "x" axis. Since the range of g(x) is all the values of "y" that are smaller or equal to zero, if we translate 5 units in the negative direction of the y-axis the range is:

R(f(x))=\mleft\lbrace y\parallel y\mright?\le5\rbrace

or in interval notation:

R(f(x))=(-\infty,-5\rbrack

Wewaii [24]

Answer:

b=2

Step-by-step explanation:

First multiply everything in the parenthesis by the 2 outside of them then combine like variables to get the equation 5b-6=4 then subtract 6 from both sides then divide by 5 to get b=2.

Each year the US Environmental Protection Agency (EPA) releases fuel economy data on cars manufactured in that year. Below arc s
fomenos

Answer:

Follows are the solution to this question:

Step-by-step explanation:

Please find the complete question in the attachment file.

n_1 = 26 \\\\ x_1 = 16.12 \\\\s_1 = 3.58\\\\n_2 = 26\\\\ x_2 = 19.85 \\\\ s_2 = 4.51

H_0: u_1 = u_2\\\\H_1: u_1 \neq u_2

Using formula:

\to S^{2}_{p}=\frac{S^{2}_{1}(n_1 -1)+ S^{2}_{2}(n_2-1)}{n_1+n_2-2}

\to Sp^2 = \frac{((26-1) \times (3.58^2) + (26-1) \times (4.51^2))}{(26+26-2)}

          = \frac{((25) \times 12.8164 + (25) \times 20.3401 )}{(26+24)}\\\\ = \frac{(320.41 + 508.5025)}{(50)}\\\\ = \frac{(828.9125)}{(50)}\\\\=16.57825

\to Sp = 4.0716

Calculating the value of standard error:

\to SE = Sp \times \sqrt{\frac{1}{n_1}+\frac{1}{n_2}}

          =4.0716 \times \sqrt{\frac{1}{26}+\frac{1}{26}}\\\\=4.0716 \times \sqrt{\frac{1+1}{26}}\\\\=4.0716 \times \sqrt{\frac{2}{26}}\\\\=4.0716 \times \sqrt{\frac{1}{13}}\\\\=4.0716 \times 0.277 \\\\=1.1278332\\\\= 1.1293

Calculating the value of test statistic:

Formula:

\to t = \frac{(x_1-x_2)}{SE}

      = \frac{(16.12 -19.85)}{1.1293}\\\\= \frac{(-3.73)}{1.1293}\\\\=-3.303

Calculating the value of Degree of freedom:

= n_1+n_2 -2 \\\\= 26+26 -2 \\\\= 52 -2 \\\\= 50

Because the P-value is a 2-tailed test = 0.0018

Thus they reject H0, because of P-value < 0.05,

Yeah, certain data show clearly that the means are different.
