Answer:

Step-by-step explanation:

Let “x” be the weight of the bottle and “y” is weight of honey.

We know the total weight of bottle full of honey is 1000 g.

So Equation 1 is x + y = 1000 g

And with half of the honey, we know the total weight is 600g.

Equation 2: x + (y/2) = 600 g

y/2=600 - x

y= 2 (600 - x)

y= 1200 - 2x

We can replace “y” with 1200 - 2x in Equation 1:

x + 1200 - 2x = 1000

x = 200 g

Weight of the bottle is 200 g.

Answer:

A. Mean = 402.5

B. Variance = 77,556.25

C. Standard Deviation = 278.49

Step-by-step explanation:

Let's calculate the mean, variance and standard deviation of the set of numbers given:

A. Mean = (45 + 340 + 400 + 825)/4 = 1,610/4 = 402.5

B. Variance [(45 - 402.5)² + (340 - 402.5)² + (400 - 402.5)² + (825 - 402.5)²]/4 = [(127,806.25 + 3,906.25 +6.25 + 178,506.25/4 = 77,556.25

C. Standard Deviation = √Variance = √77,556.25 = 278.49

The head of a computer science department is interested in estimating the proportion of students entering the department who wil

olya-2409 [2.1K]

Answer:

Step-by-step explanation:

From the given information:

At 95% Confidence interval level,Level of significance $\alpha$ 0.05, the value of Z from the standard normal tables = 1.96

Margin of Error = 0.10

Let assume that the estimated proportion = 0.5

therefore; the sample size n can be determined by using the formula: $n =(\dfrac{Z}{E})^2 \times p\times (1-p)$

$n =(\dfrac{1.96}{0.1})^2 \times 0.5\times (1-0.5)$

$n =(19.6)^2 \times 0.5\times (0.5)$

n = 96.04

n $\approx$ 96
