A large bakery makes cakes in two shifts: shift A and shift B. Suppose that, on average, cakes from shift A weigh
7.4 kg with a standard deviation of 0.2 kg. For shift B, the mean and standard deviation are 7.0 kg and 0.1 kg,
respectively.
Every day, the bakery takes an SRS of 25 cakes from each shift. They calculate the mean weight for each sample,
then look at the difference (A - B) between the sample means.

Subtract 11x - 4y from the sum of 15x + 15y and - 18x + 15y.
Answer:
-14x + 34y
Step-by-step explanation:
First, find the sum of the two expressions by adding like terms:
(15x + 15y) + (-18x + 15y)
= -3x + 30y
Now, subtract 11x - 4y, again by combining like terms:
(-3x + 30y) - (11x - 4y)
= -14x + 34y
So, the answer is -14x + 34y

What is Basic Proportionality Theorem?When a line parallel to one side of a triangle intersects the other two sides in distinct points, the other two sides are divided in the same ratio.
The fundamental proportionality theorem can be used to calculate the lengths of two sides of a triangle divided by a line drawn parallel to the third side. It can also be used to determine the relationship between two equiangular triangles.
We have
RT= x+ 4
TQ= x- 3
RV= x+ 10
As, TV || QS
By using Basic Proportionality Theorem
RT / TQ = RV / VS
(x+ 4) / (x- 3) = (x+ 10)/ x
x² + 4x = x² -3x + 10x - 30
4x - 7x = -30
-3x = -30
x= 10
Thus, the required value is 10.

Hello i need help please
Answer:
radius = 5 cm
height = 10 cm
Volume = 261.8 cm³
Step-by-step explanation:
Radius (r) = 5 cm
Height (h) = 10 cm
Volume of the cone (V) = ⅓πr²h
Plug in the values
V = ⅓*π*5²*10
V = ⅓*π*25*10
V = 261.8 cm³ (nearest tenth)
