Answer:
∠a and ∠d; ∠b and ∠c
Step-by-step explanation:
The two triangles as similar triangles and the scale factor is 2 : 1
The sides measuring 6 and 3 are corresponding sides
The sides measeuring 8 and 4 are ocrreposnding sides
⇒ ∠a and ∠d are corresponding angles
The sides measuring 8 and 4 are corresponding sides
The sides measeuring 4 and 2 are ocrreposnding sides
⇒ ∠b and ∠c are corresponding angles
Answer: 4
Step-by-step explanation:8 + 9 = 17 you take what he paid 13 and subtract 13 from 17 and you get 4. 4 is how many dollars off he got.
Answer:
<u></u>
Explanation:
Following the fundamental counting principle, the number of selection options is the product of the number of the different selection options for the 11 men by the number of different selection options for 17 women.
1. Number of different selection options for 11 men
Since the order does not matter (i.e. for 11 given men it is the sae any order in which they are selected), the number of different selections is given by the formula of combinations:
You want to select 11 men from a sample of 15 men, then:
2. Number of different selection option for 17 women
Following the same reasoning, to select 17 women from the sample os 21 women:
<em>3. Number of different selection options available if 11 men and 17 women are to be selected bor the trial:</em>
As explained above, compute the product: C(15,11) × (C21,17):
- 1,365 × 5,985 = 8,169,525 ← answer
Answer:
9.
Step-by-step explanation:
3^-2 / 3^-4 = 3^(-2 - -4)
= 3^(-2+4)
= 3^2
= 9.
