Answer:
Jiri is 12 years old
Step-by-step explanation:
To start off we need to make an equation. Since we know both of their ages add up to 48 and that Pamela's age is 3 times Jiri's age we can say x(Jiri's Age) + 3x(Pamela's age) =48 --> x+3x=48
Now we have the equation x+3x=48, and we need to solve it.
First combine like terms
4x=48
Now divide both sides by 4
x=12
And now since we are using Jiri's age as x we know Jiri is 12 years old.
It is 22 my guy because i think it is 22
Answer:
Step-by-step explanation:
it is a vertical translation.
for horizontal translation
f(x)=(x-12)²
Answer:
B. Median is greater than the mean and the majority of data points are to the right of the mean.
Step-by-step explanation:
Mean = sum(x × p(x))
= (1×0.1)+(2×0.15)+(3×0.2)+(4×0.45)+(5×0.1)
= 3.3
Probability of more than 3.3 is:
0.45 + 0.1 = 0.55 > 0.5
Answer:
x= 11/12
Step-by-step explanation:
12x - 1 = 10
12x = 10 + 1
12x = 11, divide 11 by 12
you can't divide it evenly so leave it as a fraction.
