Answer:

f^{-1}(x)=\dfrac{x+3}{4}

Step-by-step explanation:

Given: f(x)=4x-3

We need to find the inverse.

Step 1: Set f(x)=y

y=4x-3

Step 2: Switch x and y

x=4y-3

Step 3: Solve for y

x+3=4y

y=\dfrac{x+3}{4}

Hence, The inverse of given function is y=\dfrac{x+3}{4}

<span>f(x) = 4x - 3
.
The problem asks you to find f(-1).
.
All that this is telling you to do is to evaluate f(x) when x equals -1. So, just go to the
given f(x) and substitute -1 for every x. 
.
Starting with:
.
f(x) = 4x - 3</span>

The Blazers hockey team has won 7 of its first 12 games.
Step2247 [10]

Answer:

The Rockets' team has the better record.

Step-by-step explanation:

  • The Blazers hockey team has played 12 games but they won only 7 out of the 12 games, so that means that they loss the other 5 games. So that makes the Blazers record 7 wins and 5 losses.

  • The Rockets' team has played 8 games but they won only 5 out of the 8 games, so that means that they loss the other 3 games. So that makes the Rockets' record 5 wins and 3 losses.

  • So, the Rockets' team has the better record because they loss less games than the Blazers team did.

What is the measurement of N?<br> A) 45° <br> B) 90° <br> C) 100° <br> D) 180°
puteri [66]
N would equal 45° since the tiny square means its 90°. 90-45=45.

Which of the following is NOT true for a hypothesis test for​ correlation? Choose the correct answer below. A. If ​|r|less than
pantera1 [17]

Answer:

Answer explained

Step-by-step explanation:

From the information, the true statements for a hypothesis test for correlation is,

If the​ P-value is less than or equal to the significance​ level, we should reject the null hypothesis and conclude that there is sufficient evidence to support the claim of a linear correlation.

If |r| less than or equals critical value, we should fail to reject the null hypothesis and conclude that there is not sufficient evidence to support the claim of a linear correlation.

If the​ P-value is greater than the significance​ level, we should fail to reject the null hypothesis and conclude that there is not sufficient evidence to support the claim of a linear correlation.

<u>Explanation</u>

According to the decision rule of P-value approach, observe that if the​ P-value is less than or equal to the significance​ level, then there is evidence to reject the null hypothesis and conclude that there is sufficient evidence to support the claim of a linear correlation.

Similarly, if the​ P-value is greater than the significance​ level, we should fail to reject the null hypothesis and conclude that there is not sufficient evidence to support the claim of a linear correlation.

According to the critical value approach, observe that if the test statistic value is greater than the critical value, then there is evidence to reject the null hypothesis and conclude that there is sufficient evidence to support the claim of a linear correlation.

- If |r| greater than critical value, we should fail to reject the null hypothesis and conclude that there is not sufficient evidence to support the claim of a linear correlation.  

<u>Explanation </u>

Based on the decision rules of the hypothesis test, the false statement about the test for a correlation is, if |r| less than or equals critical value, we should fail to reject the null hypothesis and conclude that there is not sufficient evidence to support the claim of a linear correlation.

Using elimination method, what will be the value of y after solving -x - y = 5 and -x + 4y = 15?
natka813 [3]

9514 1404 393

Answer:

  y = 2

Step-by-step explanation:

The variable x can be eliminated by subtracting the first equation from the second.

  (-x +4y) -(-x -y) = (15) -(5)

  5y = 10 . . . . . . . simplify

  y = 2 . . . . . . . . . divide by 5

PLEASE HELP ME!!!!
Damm [24]

Answer:

  • sin C=h/a
  • substitution property of equality
  • commutative property of multiplication

Step-by-step explanation:

Because two points determine a line, you can draw altitude​ BD perpendicular to AC with height h. By the definition of a sine ratio, <u>sin(C) = h/a</u>, which can be rearranged into​ a·sin(C) = h​. The area of △ABC is A=1/2bh. The <u>substitution property of equality</u> can be used to write A=1/2b(a sinC), which becomes A=1/2ab(sinC) by the <u>commutative property of multiplication</u>.

___

The mnemonic SOH CAH TOA reminds you that the sine ratio is ...

  Sin = Opposite/Hypotenuse

Here, the side of the right triangle opposite angle C is designated "h", the height of ∆ABC. The hypotenuse of that right triangle is side "a". So ...

  sin(C) = h/a

__

The substitution property of equality lets you replace any expression with its equal. Here, we have h=a·sin(C), so we can use a·sin(C) in place of h in the formula for triangle area:

  1/2bh = 1/2ba·sin(C)

__

The commutative property of multiplication lets you rearrange the order of the factors in a product, so ...

  ba = ab

and

  A = 1/2ba·sin(C) = 1/2ab·sin(C)
