The average in January is -36°
The average in July is 17° warmer
So add 17 to -36
The average in July is -19°C
Answer:
D
Step-by-step explanation:
To be an arithmetic sequence, the numbers have to be added or subtracted by a constant number. D is not the answer because -2+6 equals 4, but 4+6 doesn't equal -6, so D cannot be a arithmetic sequence.
Answer: The answer is (B) They show direct variation because y=x+2 and 10-5=12-7.
Step-by-step explanation: We are given two points (5 7) and (10, 12) and we are to select the correct statement about the two given points.
Since we have
7 = 5 + 2 and 12 = 10 + 2, so we can directly say that the equation of the line passing through the two points will be
y = x + 2.
Since we can directly find the relation between x and y, so we can say that they show direct variation because y=x+2 and 10-5=12-7.
Thus, the correct option is (B).
Applying the trigonometry ratios, the correct option is: B. none of these are correct.
<h3>What are the Trigonometry Ratios?</h3>
The trigonometry ratios are SOH CAH TOA, which are used for solving a right triangle.
Use the trigonometry ratio to find out which option is correct.
Cos Z = adj/hyp = 61/CZ, so option A is incorrect.
Sin Z = opp/hyp = 73/CZ, so option C is incorrect.
Tan Z = opp/adj = 73/61, so option D is incorrect.
Thus, the answer is: B. none of these are correct.
