Replace x and y with known values:
10 = a x b(1) and 20= axb(2)
We can find that a x b must equal 10
Replacing a and b with with numbers we find that a = 5 and b = 2
So now you Ming that in the equation you can find the answer would be (3,30)
Answer: 0.267
Step-by-step explanation:
The relative frequency is the number of times that we obtained a given outcome divided by the total numer of trials.
In this case we have 75 trials.
in 20 trials the outcome was a 3.
Then the relative frequency of the event "spin a 3" is:
p = 20/75 = 0.266... = 0.267
Answer:
27
Step-by-step explanation:
if you do the triangle formula bxh/2
9x6/2=27
Answer:
BC = 96
Step-by-step explanation:
Since AD is an altitude, then ∠ ADC = 90° , thus
4x + 10 = 90 ( subtract 10 from both sides )
4x = 80 ( divide both sides by 4 )
x = 20
Thus
BC = BD + DC
= 2x + 3x - 4
= 5x - 4
= 5(20) - 4 = 100 - 4 = 96
