Answer:
13 : 33
Step-by-step explanation:
hearts : all shapes = hearts : (hearts + circles) = 13 : (13 +20) = 13 : 33
Answer:
The degrees of freedom associated with the critical value is 25.
Step-by-step explanation:
The number of values in the final calculation of a statistic that are free to vary is referred to as the degrees of freedom. That is, it is the number of independent ways by which a dynamic system can move, without disrupting any constraint imposed on it.
The degrees of freedom for the t-distribution is obtained by substituting the values of n1 and n2 in the degrees of freedom formula.
Degrees of freedom, df = n1+n2−2
= 15+12−2=27−2=25
Therefore, the degrees of freedom associated with the critical value is 25.
Answer with explanation:
→The Exact meaning of Probability is Chance.It Means ,that Something will happen or not in terms of rational numbers.
→As, Probability of an event lies between ,0 to 1, means ,the result is not Precise ,whether it will happen surely that is exactly 100% or it will not, that is 0%.Percentage of happening of anything lies between 0% to 100%.
→0 ≤ Probability ≤ 1,shows that ,if we represent it on the number line, it is Scattered from ,0 to 1.
These three reasons are enough to verify that, Probability can't be used to Predict exactly ,the result of an Activity.It is just representation in terms of rational number.
Once you get to "5" you start rounding up, so the least would be 250.
First solve for one variable
(I chose bottom equation because it’s easier)
Get y alone: Y = 5x
Now that we have y we can plug y into the top equation
Plug in 5x for y: 2x + 5x = 7
Solve for x: 7x = 7
X = 1
Now plug in the x value into the bottom equation to solve for y
Y = 5(1)
Y= 5
So, x = 1 and y = 5
