Answer:
25.15 ponds is the weight of two year old baby corresponds to 10th percentile.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 29 pounds
Standard Deviation, σ = 3 pounds
We are given that the distribution of weight of two year old babies is a bell shaped distribution that is a normal distribution.
Formula:

We have to find the value of x such that the probability is 0.10
P(X < x)
Calculation the value from standard normal z table, we have,

Thus, 25.15 ponds is the weight of two year old baby corresponds to 10th percentile.
John sold 30U

Answer:
Step-by-step explanation:
a³-b³=(a-b)(a²+ab+b²)
6³-1=6³-1³=(6-1)(6²+6*1+1²)=5×43
so 6³-1 is divisible by 5.
Answer:
Y=4
Step-by-step explanation:
Because the two triangles are congruent you can set the two expressions equal to each other and solve from their.
step 1 ) 8Y = 6Y + 8
step 2 ) isolate the variable to one side 8Y-6Y= 8 => 2Y = 8
step 3 ) solve for Y 2Y/2 = 8/2
Solution Y=4
