Angle Z should be 20
Angle Y should be 55
Angle X should be 105
Please find the diagram in the attachment for a better understanding of the solution provided here.
We will use the Pythagoras' Theorem here. The right triangle is PQR. Because it is a right triangle, therefore, we can use the Pythagoras' Theorem here.
Thus, as required by you we have successfully proven that the value of PQ=16.7
2x^2 + 5x + 3
4x + 5x + 3
9x + 3
Answer:
17.6
Step-by-step explanation:
<u>Final Answer:</u>
mean = 4 sundaes
<u>Solution:</u>
each bowl of sundaes contains 3 sundaes.
- two scoops = 4 sundae bowls
- I scream = 6 sundae bowls
- dream scream = 2 sundae bowls
(plus 3, the number three represents how many sundae's there are in a bowl)
(divide it by 12, since there are 12 numbers in the data set)
Mean = (4 + 4 + 4 + 6 + 6 + 6 + 2 + 2 + 2 + 4 + 4 + 4) ÷ 12
= 48 ÷ 12 = 4
