Select the store with the least expensive ice cream per scoop. Choose 1 answer

geniusboy [140]

Answer:

Store A

Step-by-step explanation:

A) The price per scoop is the slope, or 0.75 dollars, or 75 cents.

B) The slope is y2 - y1 / x2 - x1. Plugging in the values, we get 8-8 / 3-3 = 1. Therefore, the price per scoop is 1 dollar.

C) Two points on the graph are (2,3) and (4,6). Their slope is (6 - 3) / (4 - 2) = 3/2 = 1.5. The price peer scoop is 1.5 dollars.

The cheapest ice cream per scoop is Store A.

hope this helps! <3

Multiply the exponents.
So 10 ×4/5=
40/5
=8
Thus (243k^10)^4/5 is 243k^8

Meth Barie's ice cream shop wants to decide whether to introduce a new ice cream flavor. They randomly selected 15 customers at

Marianna [84]

Answer:

Meth Barie's ice cream shop should not introduce the new ice cream flavor.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 4.01

Sample mean, $\bar{x}$ = 4.4

Sample size, n = 15

Alpha, α = 0.1

Sample standard deviation, s = 1.6 minutes

First, we design the null and the alternate hypothesis

$H_{0}: \mu \leq 4.01\\H_A: \mu > 4.01$

We use one-tailed t test to perform this hypothesis.

Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}} }$

Putting all the values, we have

$t_{stat} = \displaystyle\frac{4.4 - 4.0}{\frac{1.6}{\sqrt{15}} } = 0.968$

Option B) 0.968

Rejection region:

Now, $t_{critical} \text{ at 0.10 level of significance, 9 degree of freedom } = 1.345$

So the rejection region would be a value of t-statistic greater than 1.345.

Option B) t > 1.345

Conclusion:

Since,

$t_{stat} < t_{critical}$

We fail to reject the null hypothesis and accept the null hypothesis. Meth Barie's ice cream shop should not introduce the new ice cream flavor.

(4m-3n)^2 Multiplying Polynomials

Sindrei [870]

Answer:

4m²-24mn+9n²

Step-by-step explanation:

Separate equation out so it is (4m-3n)×(4m-3n)
FOIL (First, Outside, Inside, Last) your polynomial
Should have equation 4m²-12mn-12mn+9m²
Combine like terms
Result: 4m²-24mn+9m²
