Answer:
No, the two events "being in high school" and "GPA above 3.0" are not independent.
Step-by-step explanation:
If two events A,B are independent
P(high school | above 3.0) =
P(high school) =
So,0.35 ≠ 0.6
Since P(high school | above 3.0) ≠ P(high school), the events "being in high school" and "GPA above 3.0" are not independent.
The grocer prepared total 110 samples.
<em><u>Explanation</u></em>
Suppose, the total number of samples the grocer prepared is
By lunchtime, the grocer has given out 5 fewer than half the total number of samples. So, the number of samples given out by lunchtime
Now, it is given that she gives out 50 samples before lunch. That means...
So, the total number of samples the grocer prepared is 110.
Answer:
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−5−5(6x−8)=−5x+19
−5+(−5)(6x)+(−5)(−8)=−5x+19(Distribute)
−5+−30x+40=−5x+19
(−30x)+(−5+40)=−5x+19(Combine Like Terms)
−30x+35=−5x+19
−30x+35=−5x+19
Step 2: Add 5x to both sides.
−30x+35+5x=−5x+19+5x
−25x+35=19
Step 3: Subtract 35 from both sides.
−25x+35−35=19−35
−25x=−16
Step 4: Divide both sides by -25.
−25x

Answer:
69.12
Step-by-step explanation:
i used a calculator and the formula
Half of the cards are red and half of them are black
so the answer is 1/2
or you can say that 26 are red and 26 are black
26/52 = 1/2
