Answer:
-18
Step-by-step explanation:
Answer:
Step-by-step explanation:
for 1 cube of 6 sides, it takes 5 grams
so 1 side is 5/6th grams
now how many sides of small cubes are shown is 42
42*5/6=35 grams
Answer:
The probability is 0.97682
Step-by-step explanation:
We start by finding the z-values of the runner times given.
Mathematically;
z-score = (x-mean)/SD
From the question, mean = 13 seconds and SD = 0.3 seconds
So for 12.4 seconds, we have;
z = (12.4-13)/0.3 = -0.6/0.3 = -2
For 14 seconds, we have;
z = (14-13)/0.3= 1/0.3 = 3.33
So the probability we want to calculate is;
P(-2<z<3.33)
We can find this using the standard normal distribution table
Mathematically;
P(-2<z<3.33) = P(z<3.33) - P(z < -2)
Using the standard normal distribution table, the value of this is;
P(-2<z<3.33) = 0.97682
Answer:
The slope is 
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
we have the points
(-2, 7) and (4, 9)
substitute the values in the formula
Simplify
Answer:
b=24
Step-by-step explanation:
VT^2 + (2b)^2 = 67^2
VT^2 + (b+24)^2 = 67^2
-> (2b)^2 = (b+24)^2
-> 2b = b+ 24
-> b = 24
