Answer:
a) en cuántas filas la suma es igual?
2+7+2+0+2=13
0+1+6+1+0=8
2+0+2+8+1=13
es igual en dos filas la primera y la última
b)en cuántas columnas la suma es igual?
2+0+2=4
7+1+0=8
2+6+2=8
0+1+8=9
2+0+1=3
es igual en dos columnas la segunda y la tercera
listo :)
Step-by-step explanation:
Y-2=1/4(x+8) is your answer
Explanation
Desmos
$0.25 you just have to multiply .65 times 5 for site A which is $3.25 and for sure b just plug in 5 for x and multiply by .60 which gives you $3.00 so site A gives you $0.25 more
Answer:
E(x)=0.15
V(x)=0.3075
S(x)=0.5545
Step-by-step explanation:
The mean of a discrete variable is calculated as:
where are the values that the variable can take and are their respective probabilities.
So, if we call x the number of defective transistors in cartons, we can calculate the mean E(x) as:
Because there are 0 defective transistor with a probability of 0.92, 1 defective transistor with a probability of 0.03, 2 defective transistors with a probability of 0.03 and 3 defective transistors with a probability of 0.01.
At the same way, the variance V(x) is calculated as:
Where
So, the variance V(x) is equal to:
Finally, the standard deviation is calculated as:
1. My number has two digits.
- 59 is a two-digit number. ✔
2. Double my number is less than 150.
- Double of 59 is 118, which is less than 150. ✔
3. I am not divisible by 12.
- Since 59 is an odd number, hence it is not divisible by 12. ✔
4. My digits are different from each other.
- The digits 5 and 9 are different. ✔
5. The second digit in my number is divisible by an odd number.
- 9 is divisible by an odd number, i.e. 3. ✔
6. My first digit is less than my second digit.
7. My digits add up to 14.
Therefore, the required number is .
