Answer:
B
Step-by-step explanation:
The probability of obtaining a 3 is
P(3) =
Then after 30 spins the predicted number of times it should land on 3 is
30 × = 5
Answer:
1) Change the length of side AB to 2 feet
Step-by-step explanation:
Given that both structures are similar, it follows that the ratio of their corresponding lengths are equal.
To find out what should be the correct length of AB that she should change to, set up the proportion showing the ratio of 2 corresponding lengths of both structures. Thus:
We will assume AB is unknown.
PR = 7.5 ft
AC = 2.5 ft
PQ = 6 ft
Plug in the values into the equation
Cross multiply
Divide both sides by 7.5
The architect should change the length of AB to 2 ft
First you multiply 2.20 and 2.5 which gives you 5.5, then you multiply 2.20 and 1.2 which gives you 2.64, after the multiplying, you add your totals (5.5 + 2.64) and that equals 8.14. So he spent a total of $8.14 on apples.
Answer: that's false

Answer:
3(27) = 3(25 + 2) = TURE
Step-by-step explanation:
Left side: Use long multiplication:
| | 3
× | 2 | 7
Multiply 7 by the digit in the top row:
| | 3
× | 2 | 7
| 2 | 1
Multiply 2 by the digit in the top row:
| | 3
× | 2 | 7
| 2 | 1
| 6 | 0
Add:
Answer: 81
Right Hand: Simplify the following:
3 (25 + 2)
Hint: | Evaluate 25 + 2.
25 + 2 = 27:
3×27
Hint: | Multiply 3 and 27 together.
3×27 = 81:
