rodikova [14]
Cups of flour=15  3/4=15+ 3/4=(4*15+3)/4=63/4
Cups of sugar=10  1/2=(2*10+1)/2=21/2

We solve this problem by rule of 3:

63/4 cups of flour--------------100 people
x------------------------------------ 25 people

x=(63/4 cups of flout * 25 people)/100 people=1575/400 cups of  flour=
=63/16=(3*16+15)/16=3  15/16  cups of flour.

21/2 cups of sugar-----------------100 people
x-----------------------------------------25 people

x=(21/2 cups fo sugar * 25 people) / 100 people=525/200 cups of sugar= 21/8 =(2*8+ 5)/8=2   5/8 cups of sugar.

Answer:  3  15/16  cups of flour and 2  5/8 cups of sugar.

Assume that the weight of two year old babies have distribution that is approximately normal with a mean of 29 pounds and a stan
Lana71 [14]

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:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

We have to find the value of x such that the probability is 0.10

P(X < x)  

P( X < x) = P( z < \displaystyle\frac{x - 29}{3})=0.10  

Calculation the value from standard normal z table, we have,  

P(z < -1.282) = 0.10

\displaystyle\dfrac{x - 29}{3} = -1.282\\x = 25.154 \approx 25.15

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