a package of  8 eggs costs $1.98 hmmmmmmmm how much is it for just 1 egg from that pack?

well, how many times does 8 go into 1.98?   1.98 ÷ 8 = 0.2475.

the package of 18 eggs, has the <u>same unit price</u>, namely each egg in that package costs the same as each individual egg on the other one.

well, we know the price of each egg on the other is 0.2475, how much will it be for all 18 eggs on that package?  0.2475 * 18.

so, you see, we first get the unit price, from the first package, and use that to get the price of the second package.

It would be A. because to find out how much 18 eggs would cost you would need to figure out by dividing $1.98 and 8.
hope this helped :)

Which of the following is the solution set to the equation: 2x(x-3)(4x+1)=0?
Troyanec [42]

Answer:

(1) {-1/4, 0, 3}

Step-by-step explanation:

Step 1: Factor left side of equation.

2x(4x+1)(x−3)=0

Step 2: Set factors equal to 0.

2x=0 or 4x+1=0 or x−3=0

x=0 or x= −1/4 or x=3

The cost of a daily newspaper varies from city to city. However, the variation among prices remains steady with a standard devia
My name is Ann [436]

Answer:

|t| =|-0.96|=0.96< 2.718

since calculated' t' value is less than tabulated value 't'.

we accept null hypothesis at 1 % level of significance.

The data support the claim that the mean cost of a daily news paper is  $1.00

Step-by-step explanation:

<u>Step:-(1)</u>

Given the sample size n = 12

Given Twelve costs yield a mean cost of $0.95 with a standard deviation of $0.18

mean of the sample(x⁻) = $0.95

Standard deviation of sample (S) = $0.18

Given claim that the mean cost of a daily newspaper is $1.00.

The mean of the population 'μ' =  $1.00.

<u>Null hypothesis:</u>-H₀:'μ' =  $1.00.

<u>Alternative hypothesis</u>: H₁:'μ' ≠  $1.00.

<u>level of significance ∝ = 0.01</u>

<u>Step2:-</u>

<u>The test statistic </u>

t = \frac{x^{-}-u_{0}  }{\frac{S}{\sqrt{n} } }

t = \frac{0.95-1 }{\frac{0.18}{\sqrt{12} } }

on calculation, we get

t = -0.96

|t| =|-0.96|=0.96

Degrees of freedom γ = n-1 = 12-1 =11

tₐ =  2.718

Calculated value t = 0.96

Tabulated value t at 0.01 level for 11 degrees for two tailed test = 2.718

since calculated' t' value is less than tabulated value 't'.

<u>conclusion</u>:-

<u>we accept null hypothesis at 1 % level of significance.</u>

<u>The data support the claim that the mean cost of a daily news paper is  $1.00</u>

Which cross-sectional shape do you find the most surprising? Which shape do you find the least surprising ? Explain why
natita [175]

Answer:

The circles were the least surprising because the base of the cone is a circle. The curves that look like bent rods were the most surprising, because I have not seen geometric figures like those before.
