<u><em>Answer: =30</em></u>
Step-by-step explanation:
This question it's about PEMDAS. This lesson it's about order of operations. p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract. It can also go left to right.
do calculate with exponent first.
2³=2*2*2=8
6+8*3
multiply left to right.
8*3=24
add left to right.
6+24
=30
Hope this helps!
Thanks!
Have a great day!
Answer:
2.6
Step-by-step explanation:
Given :
x 1 2 3 4
P(x) 0.3 0.2 ? 0.4
Σp(x) = 1
Hence, 0.3 + 0.2 +? + 0.4 = 1
0.9 +? = 1
? = 1 - 0.9
? = 0.1
For the mean :
E(X) = ΣX*P(X)
(1 * 0.3) + (2 * 0.2) + (3 *0.1) + (4* 0.4)
0.3 + 0.4 + 0.3 + 1.6 = 2.6
Hence, the mean = 2.6

Answer:
61,01%
Step-by-step explanation:
We must consider that her total energy intake is the addition of the energy given by the carbohydrates, fats and proteins she takes.
1g of carbohydrates contains 4kcal
1g of proteins contains 4kcal
1g of fat contains 9 kcal.
That is: 243 g of carbohidrates is equal to 972 kcal; 41g of fat is equal to 369 kcal and 63 g of proteins is equal to 252 kcal.
If we sum up all the calories she intakes in one day, the result is= 972kcal+369kcal+252kcal=1593kcal.
Now, we make a rule of 3: If 1593kcal is the 100% of the intake, then 972kcal = 972kcal*100%/1593kcal = 61,01%
3*P + (1/6%* 3p)=
Thats the formula
basically its: 3 * p + 1/6 of 3p
