Which expression is equivalent to 2(3x-8)?​

Answer:

its b Brother

Step-by-step explanation:

Answer:

3-(-6)​ = 9

Step-by-step explanation:

3-(-6) simplifies to 3 + 6.

We would have to distribute the outside negative into the inside to get rid of the parenthesis. Then, we would add.

[tex]3-(-6)\\\\-1 * -6 = 6\\\\3-(-6)=\boxed{3+6}=9[/tex]

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

$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:

16

Step-by-step explanation:

If the ratio is 3 red marbles to 4 blue marbles we can solve this using the following:

[tex]\frac{12}{b} = \frac{3}{4}[/tex]

[tex]12 * 4 = 3b\\48 = 3b\\\frac{48}{3} = b\\b = 16[/tex]

So we have 16 blue marbles.

Based on the ratio of red to blue marbles, the number of blue marbles in the bag is 16 marbles.

The bag has red marbles to blue marbles in a ratio of 3:4.

If there are 12 red marbles, the number of blue marbles can be found by direct proportion:

3   :   4

12  :   x

Cross-multiply:

3x  = 48

x = 48/3

x = 16 blue marbles

In conclusion, there are 16 blue marbles in the bag.

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).
