Answer:
1.72 grams.
Step-by-step explanation:
We have been given that Gomez found the masses of three rocks for a science project. The first rock had a mass of 19.28 grams the second rock had a mass of 25.3 grams and the third rock had a mass of 46.3 grams.
First of all, we will add the masses of 1st and 2nd rock to find the combined mass of both rocks.
Now we will subtract the combined mass of both rocks from the mass of 3rd rock.
Therefore, the mass of the 3rd rock is 1.72 grams greater than the combined mass of the other two rocks.

Answer:
The function p = 75h represents this situation.
Step-by-step explanation:
We know the equation of linear equation in the slope-intercept form is
where
m = rate of change = slope
b = y-intercept
- Let 'h' be the number of hours
- Let 'p' be the pay
Given that Lian is paid SR 75 per hour.
so the rate of change of slope = m = 75
As there is no initial condition, so b = 0
as
y = mx+b
Now, mapping the information data into the slope-intercept form
- p = y
- m = 75
- h = x
- b = 0
Thus, the equation becomes
p = 75h
Therefore, the function p = 75h represents this situation.
VERIFICATION:
Given the equation
p = 75h
for h = 1
p = 75(1)
p = 75
Thus, Liam is paid SR 75 per hour.
To find the expected value of the distribution, we multiply each outcome by it's probability. Doing this, we get that the expected value of defects on a skateboard is of .
Outcomes and probabilities:
0 defects, 9/10 probability
1 defect, 1/20 probability
2 defects, 1/25 probability
3 defects, 1/100 probability.
Expected value:
Dividing both numerator and denominator by 4:
Thus, the expected value of defects on a skateboard is of .
