The solution to the ordered pair (3,15) is the equation y = 5x, which is letter A. This is found by substituting the value of the x into the equation and solving for y. The equation y = 5x satisfies the ordered pair (3,15) because if you substitute x with 3, the equation becomes y = 5(3) which is 15.
Answer:
Use SOH-CAH-TOA method and figure out which sign you need. SOH- Sin, CAH- Cos, TOA- Tan.
Also,
SOH- opposite/hypotenuse
CAH- adjacent/hypotenuse
TOA- opposite/adjacent
Look at the angle and see which terms you have already. For example, if you had opposite the angle and the adjacent side, you would choose tangent because its TOA. Hope that helps!
Answer:
The answer is "36"
Step-by-step explanation:
Given:
Square the above value:
Let the require value be x, then
P(z > x) = 0.025
1 - P(z < x) = 0.025
P(z < x) = 1 - 0.025 = 0.975
P(z < x) = P(z < 1.96)
x = 1.96
Therefore, <span>the positive critical value that corresponds to a right tail area of 0.025</span> is 1.96
