Answer:
x = -7
Step-by-step explanation:
5-x=12
To solve for x, you must first make the equation equal to x (to make x alone on one side).
5 - x = 12
-5 -5
-x = 7
-x(-1)=7(-1)
x = -7
Answer:
hypotenuse = 17.46
Step-by-step explanation:
The Pythagorean Theorem is a^2+b^2=c^2.
Since we are finding the hypotenuse, we must plug in 16 and 7 since they represent the lengths of both side.
16^2+7^2=c^2
256+49=c^2
305=c^2
which means we have to find the square root of c^2 AND 305, round it to the nearest hundredth, which means that;
c=17.46
Answer:
The value of y given the values of x and z in the question is -734.85
Step-by-step explanation:
This is a joint variation question.
First, we are made to know that y varies jointly as x and z.
The equation for this can be written as;
y = k * x * z
Where k is the constant of proportionality.
Let’s calculate k first.
117 = k * (-3) * (-11)
33k = 117
K = 117/33 = 3.55
Now, we proceed to get what y is when x = -9 and z = 23
Let’s plug these values into the initial equation written.
y = k * x * z
We use the value of k calculated above;
y = 3.55 * (-9) * (23) = -734.85
Answer with explanation:
1.Mean of a Data set
2. Range = Maximum value in two conferences - Minimum value in two conference
= 12 - 0
=12
The mean number of wins for teams from the two conferences is 7.65.
The range in wins is 12.
