<span>h(x)=4x2−7x−17
a get like this:
</span>h(x)=f(x)−g(x) =6x2−3x−9-(2x2+4x+8)=6x2−3x−9-2x2-4x-8=4x2−7x−17

A bullet train travels at a speed of 365km/h. In August 2001, Singapore’s record for the man’s sprint was set at 10.37 second. H
Vera_Pavlovna [14]

Answer:

It is 91.01 m/s faster than the Singaporean sprinter

Convert km/hr to m/s

U get 101.38m/s (speed of bullet train)

Speed of the Singaporean sprinter is 10.37m/s

So subtracting the train speed from the sprinter's speed,

101.38 - 10.35= 91.01m/s

Six different​ second-year medical students at Bellevue Hospital measured the blood pressure of the same person. The systolic re
mixer [17]

Answer: range= 26, variance= 80 and standard deviation= 8.94

Step-by-step explanation:

Range = highest - lowest

Range = 146 - 120

Range= 26

Let m be mean

M=mean=sum/n

Mean=(120+134+146+127+138+133) / 6

M=798/6

M=133

The standard deviation sample formula:

S.D = sqrt( Summation of |x-m|^2 / n-1)

Let start finding:

|x-m|^2

For 1st: |120-133|^2=169

For 2nd: |134-133|^2=1

For 3rd: |146-133|^2=169

For 4th: |127-133|^2=36

For 5th: |138-133|^2=25

For 6th: |133-133|^2=0

Summation of |x-m|^2 = 400

The standard deviation formula is :

S.D = sqrt( Summation of |x-m|^2 / n-1)

S.D= sqrt(400 / 5)

S.D=sqrt(80)

S.D= 8.94

Variance = (Summation of |x-m|^2 / n-1)

Variance= 400/5

Variance= 80
