Answer:
The 90% confidence interval for the difference in mean (μ₁ - μ₂) for the two bakeries is; (<u>49</u>) < μ₁ - μ₂ < (<u>289)</u>
Step-by-step explanation:
The given data are;
Bakery A
<em> </em>= 1,880 cal
s₁ = 148 cal
n₁ = 10
Bakery B
<em> </em>= 1,711 cal
s₂ = 192 cal
n₂ = 10
df = n₁ + n₂ - 2
∴ df = 10 + 18 - 2 = 26
From the t-table, we have, for two tails, = 1.706
≈ 178
Therefore, we get;
Which gives;
Therefore, by rounding to the nearest integer, we have;
The 90% C.I. ≈ 49 < μ₁ - μ₂ < 289
You have to draw a corrdinate plane to figure it out. then connect the units
I’m not sure if this is what you meant but here you go! Sorry if it’s wrong :(
The answer is -3 1/8 (the last part)
I think it’s A. i’m not very sure tho
<h2><u><em>Answer: meters.

</em></u></h2><h2><u><em>Step-by-step explanation: Let L be the length of the rectangle. We have been given that the rectangle has an area of square meters and a width of meters. Since we know that area of a rectangle is the product of its length and width. To find the length of our given rectangle we will divide the area of the rectangle by the width of our rectangle. Let us factor out our numerator by splitting the middle term. Upon canceling out x-7 from numerator and denominator we will get, Therefore, the length of our rectangle will be metered.</em></u></h2>
