Example: Oranges are sold in a bag of 5 for $2. The ratio of roanges to cost is 5:2 if i had 20 oranges for ? cost it would look like: 5/2=20/?
Answer:
x = -1
, y = 5
Step-by-step explanation:
Solve the following system:
{5 x + 3 y = 10 | (equation 1)
x = y - 6 | (equation 2)
Express the system in standard form:
{5 x + 3 y = 10 | (equation 1)
x - y = -6 | (equation 2)
Subtract 1/5 × (equation 1) from equation 2:
{5 x + 3 y = 10 | (equation 1)
0 x - (8 y)/5 = -8 | (equation 2)
Multiply equation 2 by -5/8:
{5 x + 3 y = 10 | (equation 1)
0 x+y = 5 | (equation 2)
Subtract 3 × (equation 2) from equation 1:
{5 x+0 y = -5 | (equation 1)
0 x+y = 5 | (equation 2)
Divide equation 1 by 5:
{x+0 y = -1 | (equation 1)
0 x+y = 5 | (equation 2)
Collect results:
Answer: {x = -1
, y = 5

Answer:
a. Discrete
b.Continuous
Step-by-step explanation:
a. A discrete random variable has a countable number of possible values.
-The probability of each value of a discrete random variable is between 0 and 1, and the sum of all the probabilities is equal to 1.
-The number of free dash throw attempts are countable. Hence, a Discrete Random Variable.
b. -A continuous random variable is a random variable where the data can take infinitely many values.
-A continuous random variable is a random variable is qualitative in nature.
-The amount of rainfall will take different values in different April months. Hence Continuous Random Variable.
Answer:
Solution is 34
Step-by-step explanation:
to find f(8) you plug in 8 for x in the equation
f(x)=4(8)+2=34
hope this helps.
