Which pair of undefined terms is used to define the term parallel lines?

Answer:

A

Step-by-step explanation:

Because subtraction and addition are alike just how multiplication and division are.

The inverse of f(x) is (x+6)/5, the correct option is A

Suppose that the given function is

[tex]f:X\rightarrow Y[/tex]

Then, if function 'f' is one-to-one and onto function (a needed condition for inverses to exist), then, the inverse of the considered function is

[tex]f^{-1}: Y \rightarrow X[/tex]

such that:

[tex]\forall \: x \in X : f(x) \in Y, \exists \: y \in Y : f^{-1}(y) \in X[/tex]

It simply means, inverse of 'f' is undo operator, that takes back the effect of 'f'

Given;

f(x) = 5x - 6

f^-1 (x ) = x+6/5

Let, y = f(x) and rearrange making x the subject;

y = 5x - 6 ( add 6 to both sides )

y + 6 = 5x ( divide both sides by 5 )

x = (y+6)/5

Change y back into terms of x

x  = (x+6)/5

Therefore, the answer in inverse will be (x+6)/5

Answer:

2,3

Step-by-step explanation:

The slope of the line that passes through points (1, 1) and (7, 5) is 2/3.

Slope is a notation that shows that a surface of which one end or side is at a higher level than another surface.

The formula for slope of a line that passes through two points (x₁.y₁) and (x₂,y₂) is,

y₂ - y₁ = m(x₂ - x₁)

The given points are, (1, 1) and (7, 5).

The slope of the line is given by formula m = (y₂-y1)/(x₂-x₁)

m= (5-1)/(7-1)

m = 4/6

m = 2/3

The slope of the line that passes through points (1, 1) and (7, 5) is 2/3.

Answer:

The 95% confidence interval for the standard deviation is (0.14, 0.54).

Step-by-step explanation:

The complete data and question is:

Sloth CW Ratios ; {1.5 , 1.09 , 0.98 , 1.42 , 1.49 , 1.25}

The 95% confidence interval for the standard deviation of this data is  < σ <   (two decimals - include the leading zero) .

Solution:

Compute the sample standard deviation as follows:

[tex]\bar x=\frac{1}{n}\sum x=\frac{1}{6}\times 7.73=1.2883\\\\s=\sqrt{\frac{1}{n-1}\sum (x-\bar x)^{2}}=\sqrt{\frac{1}{6-1}\times 0.2387}=0.2185[/tex]

The (1 - α)% confidence interval for the variance is:

[tex]CI=\frac{(n-1)s^{2}}{\chi^{2}_{\alpha/2}}<\sigma^{2}<\frac{(n-1)s^{2}}{\chi^{2}_{1-\alpha/2}}[/tex]

Confidence level = 95%

⇒ α = 0.05

The degrees of freedom is,

df = n - 1 = 6 - 1 = 5

Compute the critical values of Chi-square:

[tex]\chi^{2}_{\alpha/2, (n-1)}=\chi^{2}_{0.025,5}=12.833\\\\\chi^{2}_{1-\alpha/2, (n-1)}=\chi^{2}_{0.975,5}=0.831[/tex]

*Use a Chi-square table.

Compute the 95% confidence interval for the variance as follows:

[tex]CI=\frac{(n-1)s^{2}}{\chi^{2}_{\alpha/2}}<\sigma^{2}<\frac{(n-1)s^{2}}{\chi^{2}_{1-\alpha/2}}[/tex]

     [tex]=\frac{5\times (0.2185)^{2}}{12.833}<\sigma^{2}<\frac{5\times (0.2185)^{2}}{0.831}\\\\=0.0186<\sigma^{2}<0.2873\\\\=\sqrt{0.0186}<\sigma<\sqrt{0.2873}\\\\=0.1364<\sigma<0.5360\\\\\approx 0.14<\sigma<0.54[/tex]

Thus, the 95% confidence interval for the standard deviation is (0.14, 0.54).

$200/5 lamps= $40 per lamp

Final answer: $40

Using the elimination principle, the cost of one lamp is $16

Let :

3a + 5b = 176 - - - - (1)

5a + 3b = 208 - - - (2)

Multiply (1) by 5 and (2) by 3

15a + 25b = 880 - - - - (3)

15a + 9b = 624 - - - - - (4)

Subtract (3) and (4)

16b = 256

b = (256 ÷ 16)

b = $16

Therefore, the cost of one lamp is $16

Answer:

32

Step-by-step explanation:

We are finding X and it connects to the base and the height, so it is going upward only a bit, so you add the base to the height or 26 + 6 = 32.

Answer:

32

Step-by-step explanation:

All you need to do is add 26 + 6=32

p = 27

r = 0

p(1+r3) = 27

27(1+0(3)) = 27

27(1+0) = 27

27(1) = 27

27 = 27

Answer:

Step-by-step explanation:

the "mean" just means the "average"

So if the average of four numbers  = 2.6

To find the total of the four numbers, you would multiply 2.6 by 4.

2.6 x 4 = 10.4

One of the four numbers is 5. (given in the question)

This means that the total of the remaining three numbers is:

10.4 - 5 = 5.4

Then divide 5.4 by 3 to find the average of the 3 numbers.

Mean of the other 3 numbers = [tex]\frac{5.4}{3}[/tex] = ?
