Suppose 250 randomly selected people are surveyed to determine if they own a tablet. Of the 250 surveyed, 98 reported owning a t

SashulF [63]

Answer:

The true proportion for the population would be between 0.386 and 0,398 (0.392±0.06) in 95% confidence level.

Step-by-step explanation:

Confidence interval for true population proportion can be computed as p±ME where

p is the sample proportion ( $\frac{98}{250}=0.392$ )
ME is the margin of Error from the mean

and margin of error (ME) can be found using the formula

ME= $\frac{z*\sqrt{p*(1-p)}}{\sqrt{N} }$ where

z is the corresponding statistic in 95% confidence level (1.96)
p is the sample proportion ( $\frac{98}{250}=0.392$ )

N is the sample size (250)

Using the numbers

ME= $\frac{1.96*\sqrt{0.392*0.608}}{\sqrt{250} }$ ≈ 0.06

Then the true proportion for the population would be p±ME = 0.392±0.06 in 95% confidence level.

Mary is selling chocolate bars to raise money. She earns $3 for each solid milk chocolate bar sold and $4 for each caramel-fille

m_a_m_a [10]

Answer:

3m + 4c

Step-by-step explanation:

Whenever a word problem says the word earn that means the slope, also known as the rate of change, will be positive. Knowing this you can determine that both the caramel and milk chocolate slopes will be positive. After figuring all that out the only thing left to do is to make the equation. You know you have two slopes, and each slope needs a variable, so you will have to look back at the question. It is given that m represents the milk chocolate and c represents the caramel. Now all you have to do is make the slope the coefficient to the corresponding variable. The milk chocolates are 3 dollars, so the 3 goes in front of the m and the caramel chocolates are 4 dollars, so teh 4 goes in front of the 4. Since both slopes are positive no negatives or minus signs will be used in the equation. Knowing all this information you can now create the expression 3m + 4c.

URGENT! Write as an expression and simplify: the tripled product of 6a and b^2

sp2606 [1]

Answer:

$216(a)^3b^{6}$

Step-by-step explanation:

Remember that product means multiply..

we have

$(6ab^{2})(6ab^{2})(6ab^{2})=(6ab^{2})^3$

$(6ab^{2})^3=(6)^3(a)^3(b^{2})^3\\ (6ab^{2})^3=216(a)^3b^{6}$

The orbit of the space is approximatly a circle with a radius of 4100 mi. How far do the astronauts travel with each orbit?

Verdich [7]

Answer:

25748 km

Step-by-step explanation:

The distance at which astronauts travel can be obtained by calculating the Circumference of the circle.

Circumference of a circle = 2πr ; π = 3.14

Radius = 4100 km

Circumference of a circle = 2 * 3.14 * 4100

Circumference of the circle = 25748 km

Hence, astronauts travel a distance of 25748 km
