Answer:

(3x - 4) (2x + 15)

Step-by-step explanation:

6x² + 37x - 60

Using "splitting the middle term" method,

we get;

6x² + 45x - 8x - 60

= 3x (2x + 15) - 4 (2x + 15)

= (3x -4) (2x + 15)

I need help with this one <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%20" id="TexFormula1" title=" \frac{1}{3} "
Vanyuwa [196]
To solve this questions, we can turn 2 into a fractions.

2 as a fraction is 2/1 (because 2 divide by 1 is still 2)
We can now use this to get our answer. 

1/3  ÷ 2/1 
=  1/3 × 1/2    (flip the fraction and then multiply)
= 1/6          (1 x 1 / 3 x 6)

Or 0.16666.. as a decimal

Inferential statistical tests are used for all of the following except: a. describing a sample with means and standard deviation
Anika [276]

Answer:

a. Describing a sample with mean and standard deviation.

Step-by-step explanation:

Statistics can be categorized into descriptive and inferential statistics.

descriptive statistics uses data for descriptions through numerical analysis. It can be further divided in four parts.

  • Measures of Central Tendency ( Mean, Median, and Mode)
  • Measures of Frequency (Count, Percent, Frequency)
  • Measures of Position (Percentile Ranks, Quartile Ranks.)
  • Measures of Dispersion ( Range, Standard Deviation)

Inferential statistics however is based on assumptions and conclusions and generalizations drawn from samples or checks.

options b to d are all examples of inferential statistics while option a is an example of descriptive statistics.

Which inequality is true when the value of R is 18? I'ma shower the answers i can choose in the picture ​
musickatia [10]

Answer:

See below:

Step-by-step explanation:

Hello! We can check to see if the inequality is true by replacing r with 18 as we have been told to find them in which 18 as r makes the equation true.

So our equations to test for are:

-r-3>-6\\-r+3

We can input 18 as r and then we see the following are correct:

1. No, as a -21 is not greater than -6

2. Yes, as -15 is less than 6.

3. No, as 21 is not greater than 6

4. No, as -15 is not greater than 6.

Cheers!

-16 + the quotient of a<br> number and -4 is -3
alexira [117]

Answer:

76

Step-by-step explanation:

let the number be x

Then 16 + x/-4 = -3, so

x/-4 = -16-3 = -19 (add -16 on both sides)

x = -4*-19 = 76 (multiply by -4 on both sides)
