The functional equation of the line is f (x)=a*x+b
you have already a: -4 -->f (x)=-4 x+b
Now you can use the point (3;-3)
3 is the x-coordinate and -3 the f (x)-coordinate
--> -3 = -4*(3) + b Now you can solve it
-3 = -12+b (+12)
b = 9
ANSWER: f (x) = -4x + 9

Vladimir [108]

Answer:

24 hours

Step-by-step explanation:

Kristen = 8 hours

Kristen and Courtney = 6 hours

Courtney = x hours

in six hours kirsten can do 6/8 of the job

6/8 = 3/4

So kirsten is going to be doing 3/4 of the job

Courtney is only going to do 1/4 of the job

Number of hours it takes Courtney to do the job

6/x = 1/4

Cross product

6 * 4 = x * 1

24 = x

x = 24 hours

It will take Courtney 24 hours to type a 50-page paper on her own

The manager of the commercial mortgage department of a large bank has collected data during the past two years concerning the nu
ZanzabumX [31]

The <em>expected number of mortgages</em> approved per week and the standard deviation of the distribution are 2.019 and 0.024 respectively.

<u>The expected number of mortgages approved per week</u> :

  • <em>Mean = (Σfx ÷ Σf)</em>

Expected Number approved = 210 ÷ 104 = 2.019

Hence, it is expected that 2.019 mortageahes would be approved per week.

<u>The standard deviation</u> :

  • <em>Variance = [Σ(Xi - x)² ÷ Σf] </em>

  • <em>Standard deviation = √Variance</em>

Variance = (59.5414 ÷ 104) = 0.0005698

Standard deviation = √0.0005698

Standard deviation = 0.024

Therefore, the expected value and standard deviation are 2.019 and 0.024 respectively.
