Help pls I have no clue how

Goryan [66]

Answer:

Step-by-step explanation:

By using regression line calculator,

Equation of the regression line from the data given,

y = -0.38993x + 26.95184

Here, y = weekly hours of sport

x = Time to run

For x = 50 minutes,

y = -0.38993(50) + 26.95184

= 7.45534

≈ 8

Since, slope of the given regression line is negative, correlation will be negative (n).

Can someone please please help me with this question !!!

Alex_Xolod [135]

Answer: b and d

Step-by-step explanation:

Since the roots are x=2 and x=6, we can write the equation as

$f(x)=a(x-2)(x-6)$

Substituting in the coordinates of the vertex,

$-4=a(4-2)(4-6)\\\\-4=a(2)(-2)\\\\-4=-4a\\\\a=1$

So, the equation is $f(x)=(x-2)(x-6)$ .

On expanding, we get $f(x)=x^2 - 8x+12$

Write a proportion that can be used to convert 50 meters into kilometers. Solve the proportion

Levart [38]

So in a kilometer, there is 1,000 meters
so if you have 50 meters you can divide by 1,000 meters like:
50 meters/1 = 1 km/1,000 meters
which should get you 0.05 km
