Answer:
(I think) it's 10 cms because total perimeter is 30 centimeters so there will be 5 on two sides making 10,30-10=20 and 20/2=10 which makes a total of 30 (5+5+10+10)
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
Answer:
The answer is 2 hope this helped!
Step-by-step explanation:
A = base * height
A = 10 *17
A =170
170 is the correct answer
The answer is 1,000. 500(2)= 1000
