Answer:
plain = $10.50
pepperoni = $12.50
Step-by-step explanation:
x = pepperoni
y = plain
3x + 2y = 58.5
2x + 4y = 67
using substitution method, I multiplied the first system by -2 to get:
-6x - 4y = -117
+ 2x + 4y = 67
-4x = -50
x = $12.50
2(12.5) + 4y = 67
25 + 4y = 67
4y = 42
y = $10.50
Answer:
Two-tailed test.
Step-by-step explanation:
There are two types of tests:
One-tailed tests and two-tailed tests.
When we only test if the mean is less or more than a value, we have a one-tailed test.
When we test if the mean is different from a value, we have a two-tailed test.
If you were to conduct a test to determine whether there is evidence that the proportion is different from 0.30, which test would you use?
Test if it is different, so a two-tailed test.
Answer:
384 inches²
Step-by-step explanation:
The surface area of a cube is found by using 6a².
6 = the number of sides in a cube
a = the given dimension (in this case, 8 inches long)
SA = (6)8²
SA = 6(64)
SA = 384

<span>4(13.5) / 3(10) = 1.8
Example
1. 9(499) = 4491 = (200 + 299)9
For the basic properties examples are:
Addition, you can have 6 + 107 = 113 </span>
Commutative Property by moving: 107 + 6 = 113
Associative Property by grouping: (3 + 3) + (100 + 7 ) = 113
Distributive Property by allotting: 2 (3) + 107 = 113
Multiplication, you can have 6 x 107 = 642
Commutative Property by moving: 107 x 6 = 642
Associative Property by grouping: (3 + 3) x (100 + 7 ) = 642
<span>Distributive Property by allotting: 2(3) x 107 = 642<span>
