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
15m because if we add all of the you will get 12 but atleast you need some for backyard
Answer:
She can advertise for 10 days
Step-by-step explanation:
Here, we want to know for how long can Jackie advertise if she decides to buy a 4-line ad which will run for three days.
The total money she has or she wants to spend is $15.
Now if $4.35 will run for 3 days
then $15 will run for x days
4.35 * x = 15 * 3
4.35x = 45
x = 45/4.35
x = 10.34 which is approximately 10 to the nearest whole number
Answer:
Area of one of the triangles = 69.375 in² (Approx)
Step-by-step explanation:
Given:
One side of rectangle = 9.25 in
Other side of rectangle = 15 in
Diagonal create two equal right triangle.
Find:
Area of one of the triangles = ?
Computation:
⇒ Area of one of the triangles = 1/2 [One side of rectangle × Other side of rectangle]
⇒ Area of one of the triangles = 1/2 [9.25 × 15]
⇒ Area of one of the triangles = 1/2 [138.75]
⇒ Area of one of the triangles = 69.375 in² (Approx)
