Answer:
should be 27
Step-by-step explanation:
60% of 180 is 108
25% of 108 is 27
Origin = (0,0)
To find the units of distance subtract the given pair from origin
(0,4) - (0,0) = 4
Answer:
I am 76 years old.
Step-by-step explanation:
If my age is x years then:
200 - 2x = 48
-2x = - 152
x = 76.
Answer:
Step-by-step explanation:
The given parameters can be represented as:
Solving (a): P(x < 3)
This is calculated as:
----- i.e. all probabilities less than 3
So, we have:
Solving (b): Expected number of events
This is calculated as:
So, we have:
Express as decimal
Approximate to the nearest integer
Answer:
Step-by-step explanation:
First let's re-write the equation:
f(x) = 3x² - 5x + 4
If f(-2). then we can re-write the equation as:
f(-2) = 3(-2)² - 5(-2) + 4
We must solve for exponent first: (-2)² = 4
f(-2) = 3(4) - 5(-2) + 4
Then solve for multiplication:
f(-2) = 12 + 10 + 4
Finally addition:
f(-2) = 26
that means that in a function, if X = -2, then F is equal to 26
