Answer:
1. John still has 3 Apples
2. John now has 845679,63 Apples (I'm not sure if you've written the number of the multiplying fairy right...).
3. If the * is multiplying:
John now has 25937228,2 Apples.
Step-by-step explanation:
Just use the calculator.
16/2 is 8
all you have to do is divide $3.20 by 2 and compare the 2 prices.
$3.20/2 is $1.60e better unit price is the 8oz bottle
Best way to solve would be using Elimination Method. Here's how to solve.
9x + 8y = 15
9x + 8y = 30
To cancel out a variable multiply one equation with -1.
9x + 8y = 15
-1(9x + 8y = 30)
Distribute.
9x + 8y = 15
-9x - 8y = -30
Add both equations together.
0 = -15
So no solution would be your answer. I hope this helps love! :)
Answer:
z= 2.38
P = 0.008656
Step-by-step explanation:
Here n= 500 and p~= 464/500= 0.928 and q`= 1- 0.928 = 0.072
We formulate our null and alternate hypothesis as
H0 = 0.9 ; H0 > 0.9
The degree of confidence = 90%
z₀.₀₅ = 1.645 for α= 0.05
We use the test statistic
z= x- np/√npq
z= 466-500 *0.9/ √500 * 0.9(1-0.9)
z= 466- 450/ √45
z= 16/6.7082
z= 2.38
As the calculated value of z= 2.38 is greater than α =1.645 so we reject H0.
If H0 is true the P value is calculated as
P = 1- Ф( 2.38)
P = 1-0.991344=0.008656
Answer:
Lauren tutors 42 students in total
Step-by-step explanation:
She tutors for 6 hours and she teaches 7 students an hour , so we just have to multiply 7 by 6 which is 42
