Illusion [34]

Answer: Yes, Brad has enough oranges.

Step-by-step explanation:

Given :

The orange required for one bowl = 12 oz

Thus orange required for 12 bowls = \frac{12}{1}\times 12=144oz

Oranges available with Brad for 12 bowls = 10 lb = 10\times 16=160oz

(1lb=16oz)

As organges required is less than oranges available with Brad, thus Brad has enough oranges.

Suppose that W1 is a random variable with mean μ and variance σ21 and W2 is a random variable with mean μ and variance σ2. From
vivado [14]

Answer:

Step-by-step explanation:

The concept of variance in random variable is applied in solving for the value of c for the estimator cW1 + (1 − c)W2 to be most efficient. Appropriate differentiation of the estimator with respect to c will give the value of c when the result is at minimum.

The detailed analysis and step by step approach is as shown in the attachment.

For 1983 through 1989, the per capita consumption of chicken in the u.S. Increased at a rate that was approximately linear. In 1
Volgvan

We have been given that in 1983, the per capita consumption was 39.7 pounds, and in 1989 it was 47 pounds.

Let us assume t=0 corresponds to year 1980.

Hence, we can express the given information as ordered pairs as (3,39.7) and (9,47).

We can to find a linear function passing through these points. Let us first find slope of the linear function:

m=\frac{y_{2}-y_{1} }{t_{2}-t_{1}} =\frac{47-39.7}{9-3} =\frac{7.3}{6} =\frac{73}{60}

We can write the required linear function as:

y-39.7=\frac{73}{60}(t-3)

Upon simplifying  this, we get:

y=\frac{73}{60}t+\frac{721}{20}

In order to find per capita consumption in 1995, we need to substitute t=15 in this function.

y=\frac{73}{60}(15)+\frac{721}{20}=54.3

Therefore, we would expect the per capita consumption of chicken in 1995 to be 54.3.
