Question 13 (3 points)

Mathematics
1 answer:
Aloiza [94]3 years ago
4 0

Answer:

sorry

Step-by-step explanation:

What is probability? Put simply, it is the chance of an event occurring. Probability is often expressed in quantifiable terms as either a percentage or a decimal: for example, the chance of a coin landing as heads is 50% . It is impossible to be certain you can correctly predict whether the coin will land heads or tails, which makes the act of flipping the coin a random event. We can however, calculate the probability of the coin landing heads or tails.

Which equations have the same value as 3/5 (30x-15)=72 select 3
const2013 [10]

Answer:

x=4.5

Step-by-step explanation:

Given the equation  \frac{3}{5}(30x-15)=72, we simplify as:

\frac{3}{5}(30x-15)=72\\\\18x-9=72

#We further simplify as multiples of 9(divide by 9 to solve for x):

18x-9=72\\\\2x-1=8\\\\2x=9\\\\x=4.5

Hence, from our simplification  the equation has the same value as x=4.5

a water tank is draining at a constant rate if after five minutes the tank is drained by 4.5 gallons what is the rate in gallons
vova2212 [387]

Answer:

The rate is 0.9 gallon per minute

Step-by-step explanation:

Here, we have 4.5 gallons drained in 5 minutes but we are interested in calculating the rate per minute

Let the amount drained per minute be x

4.5 gallons = 5 minutes

x gallon = 1 minute

Let’s cross multiply;

x * 5 = 4.5 * 1

5x = 4.5

x = 4.5/5

x = 0.9 gallons

Find g(x), where g(x) is the translation 8 units down of f(x)=x2.
SVEN [57.7K]

Answer:

g(x) = x² - 8

g(x) = 1(x-0)² - 8

Step-by-step explanation:

f(x) = x²

we translate this parent function 8 units down thus:

g(x) = f(x) - 8

g(x) = x² - 8

in the form a( x - h)² + k:

g(x) = 1(x-0) - 8

k = (-8)

As the change is constant rather than the variable of the quantity of "x" It is a movement of the whole f(x) function eight units down.

h = 0

Because, there is no information about a stretchment of the parent function in g(x)
