Her grandma will be there 40 minutes early. If you add the hours first, then it makes it 6:35. Add the 50 minutes, 7:25 is the arrival time.
Answer:
The variance is 
Step-by-step explanation:
From the question we are told that
The sample size is n = 21
The sum of squares is 
Generally the variance is mathematically represented as

substituting values


If you have a function y = f(x), the transformation along the x-axis is given by:
y = f(x+a) ⇒ This is the translation to the LEFT by 'a' units
y = f(x-a) ⇒ This is the translation to the RIGHT by 'a' units
So you have, f(x) = 5ˣ, translated 4 unit right will give g(x) = 5⁽ˣ⁻⁴⁾
Answer:
B
Step-by-step explanation:
To put an equation in point slope form, use the equation y-y1=m(x-x2)
If the equation is y-(-4)=2(x-(1))
Then the x value must be 1 and the y value must be -4. The answer is (1,-4)
Answer:
Step-by-step explanation:
y = total cost and x = number of tons
y = 125x + 7500
the total cost for transporting 15 tons...sub in 15 for x
y = 125(15) + 7500
y = 1875 + 7500
y = $ 9375 <===== total cost
