It would be -4. subtracting a positive is the same as adding a negative
First you convert 1/4 so it would have the same denominator as 3/8:
1/4=2/8
Now you compare the fractions
2/8 ? 3/8
3/8 is more, so the dish with 3/8 of an orange has more.
Hope this helps!
Using the t-distribution, the critical value needed is: t = 2.2622.
<h3>How to find the critical value for the t-distribution?</h3>
The critical value is found using a calculator, with two parameters:
- The number of degrees of freedom, which is one less than the sample size.
For this problem, we have a confidence level of 95% and 10 - 1 = 9 df, hence the critical value is t = 2.2622.

Answer:
$8.77
Step-by-step explanation:
Total cost = 2.89 + 18.4*1.75
= 2.89 + 32.2
= $35.09
Amount paid by each person = $35.09/4
= $8.77
Answer:
<h2>SA = 5645cm²</h2>
Step-by-step explanation:
We have three pairs of congruent rectangles
9cm × 4m; 9cm × 5cm and 4m × 5cm
We know 1m = 100cm, therefore 4m = 400cm
The formula of an area of a rectangle l × w:
A = l · w
Substitute:
A₁ = 9cm · 4m = 9cm · 400cm = 3600cm²
A₂ = 9cm · 5cm = 45cm²
A₃ = 4m · 5cm = 400cm · 5cm = 2000cm²
Calculate the surface area:
SA = A₁ + A₂ + A₃
SA = 3600cm² + 45cm² + 2000cm² = 5645cm²
