<span>f(k) = k2 + 2k + 1 = (k+1)^2
The range is what the function gives to you f(k)=25=5^2 or (-5)^2
f(k)=64=8^2 or (-8)^2

You need to find the k values for these boundary values to find the domain. 
Good luck :)</span>

Find the inner product for (7, 2) * (0, -2) and state whether the vectors are perpendicular.
Andrews [41]

Answer: A

Step-by-step explanation:

To find the inner product of two vectors (a,b) and (c,d) you would use the equation (a * c) + (b * d)

So for (7,2) and (0,-2) the inner product would be

(7 * 0) + (2 * -2)

= 4

The vectors are only perpendicular when the inner product is equal to 0. Since it is equal to -4 in this case, the vectors are not perpendicular.

A -4; no

10 (2y + 2) - y = 2 (8y - 8)
Ede4ka [16]

Answer:

10(2y+2)= 10.2y+10.2

20y+20-y

2(8y-8)=2.8y-2.8

20y+20-y=16y-16

20y-16y-y=-20-16

3y=-36

36/3y=?

y=-12

Hi All,
tangare [24]

Answer:

a) modal number of teachers in a car is 3

b) median number of teachers in a car is 3

c) mean number of teachers in a car is 2.5

Step-by-step explanation:

  • modal number is 3 because that is the highest frequency of  numbers of cars
  • median number is 3 because it is the middle number when you expand the frequency table.
  • mean number is 2.5 because that is the approximate average of all the numbers.

Use the given information to bound the p-value of the F statistic for a one-tailed test with the indicated degrees of freedom. F
lianna [129]

Answer:

The range of the <em>p</em>-value is: 0.050 < <em>p</em>-value < 0.100.

Step-by-step explanation:

For checking the equivalence of two population variances of independent samples, we use the <em>f</em>-test.

The test statistic is given by:

F=\frac{S_{1}^{2}}{S_{2}^{2}}\sim F_{\alpha, (n_{1}-1)(n_{2}-1)}

It is provided that the hypothesis test is one-tailed.

The computed value of the test statistic is:

<em>F</em> = 4.23.

The degrees of freedom of the numerator and denominator are:

df_{1}=4\\df_{2}=5

Use MS-Excel to compute the <em>p</em>-value as follows:

Step 1: Select function fX → F.DIST.RT.

Step 2: A dialog box will open. Enter the values of f-statistic and the two degrees of freedom.

*See the attachment below.

Step 3: Press OK.

The <em>p</em>-value is, 0.0728.

The range of the <em>p</em>-value is:

0.050 < <em>p</em>-value < 0.100
