Answer:
Step-by-step explanation:
We require more information by I will explain in principle:
If Type A has at least 300 hours and Type B at least 400 hours.
You need to determine the Probability density function of X and Y and then subtract 1 from both
This will give you the probability of the expression.
Answer:
(12+3x)x
Step-by-step explanation:
the other 3 can be simplified into 15x, but (12+3x)x = 12x+3x^2
Answer:
The density would be 2.89 g/ml
Step-by-step explanation:
To find this, we first need to find the mass of the rock. we can do this by subtracting the weight of the water and cylinder from the weight after the rock is added.
250g - 120g = 130g
Now we need to find the volume. To get this, we subtract the volume of the water before and after the rock is added.
75ml - 30ml - 45ml
Now we use the density formula and solve
D = m/v
D = 130g/45ml
D = 2.89 g/ml
Answer:
working hypothesis.
Step-by-step explanation:
Hypothesis is a technique in mathematics used to identify between two events. The event is tested for hypothesis using the null hypothesis and an alternative hypothesis is set to compare the results. If there are more than one hypothesis then there is working hypothesis technique used to identify the conclusion.
Answer:
Step-by-step explanation:
Equation of line
y = mx + c
m = slope and c is the intercept on y-axis
