circumference is C = πd, d = diameter.

we know the diameter is 60, so one time around the track is just C = π60 which if you plug that in your calculator, we get C ≈ 188.4955592153876.

Answer: 188.4 meters

Step-by-step explanation:

Given : Juan ran all the way around a circular track one time.

The diameter  (d) of the track is 60 meters.

The formula for circumference of a circle is given by :-

C=\pi d

Then , the total distance run by Juan is given by :-

C=(3.14)(60)=188.4\text{ meters}\ \ \ \ [\text{Put }\pi=3.14]

Hence, the total distance run by Juan = 188.4 meters

A health psychologist knew that corporate executives in general have an average score of 2.55 with a standard deviation of 0.5 o
Mumz [18]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Population mean (μ) = 2.55

Population standard deviation (σ) = 0.5

Sample size (n) = 30

Sample mean (x) = 2.76

α = 0.05

STEP 1:

Stress score in general executive (s1)

Stress score in exercising executive (s2)

Null : s1 = s2

Alternative : s1 < s2

STEP 2:

Shape of distribution = normal

Population mean (μ) = 2.55

Population standard deviation (σ) = 0.5

Sample size (n) = 30

Sample mean (x) = 2.76

α = 0.05

Decision rule :

α = 0.05 which corresponds to a t score (t0) ;

df = n - 1 = 30 - 1= 30 at 0.05 = 1.699

If :

(Test statistic (t) > t0) ; reject the Null

(right tailed test)

Test statistic (t) :

(x - μ) / (σ/√n)

(2.76 - 2.55) / (0.5/√30)

0.21 / 0.0913

= 2.30

t > t0

2.30 > 1.699

t is more extreme than t0

Hence, reject the null at α = 0.05

What is the inverse of f(x)=−3x+5?
kotykmax [81]

Answer:

f-¹(x) = (4- x)/ 3

Step-by-step explanation:

inverse of a function is nothing but the value of x in terms of f(x)

like

if we write f(x) as y we'd get

y = - 3x + 5

so, ill express x in terms of y:-

y= -3x + 4

  • adding 3x on both sides of the equation

y + 3x = -3x + 3x + 4

  • subtracting y on both sides

y - y + 3x = 4 - y

3x = 4 - y

  • dividing the whole equation by 3

x = (4 - y)/ 3

soo, the inverse of the function is x = (4- y)/ 3

mostly we write the inverse in terms of x, hey! don't get confused, when i say this, I simply mean that we're gonna replace y with x and x with f-¹(x).

therefore,

f-¹(x) = (4- x)/ 3
