Answer:
see explanation
Step-by-step explanation:
The intercepts are where the line crosses the x and y axes.
To find the x- intercept ( where the line crosses the x- axis) let y = 0 in the equation and solve for x, that is
0 + 5 = - 2x
5 = - 2x ( divide both sides by - 2 )
x = - = - 2.5 ← x- intercept ⇒ (- 2.5, 0 )
To find the y- intercept ( where the line crosses the y- axis ) let x = 0 in the equation and solve for y, that is
y + 5 = 0 ⇒ y = - 5 ← y- intercept ⇒ (0, - 5 )
Answer:
34°
Step-by-step explanation:
1. First, let's find the measure of ∠1 because since r || s, that means ∠1 = ∠7 because they're both alternate exterior angles. Alternate exterior angles are congruent.
2. (Solving for ∠1)
3. Now, since we know ∠1 = ∠7, ∠7 = 34°.
Answer:
Step-by-step explanation:
Data provided in the question:
Number of cups of tea offered = 3
Number of cups marked = 9
Number of cups tasted by each = 4
Now,
The probability that a contestant does not taste all of the samples
= contestant tastes only 2 samples of tea
=
C₆⁴ = number of ways to choose 4 cups out of 6 cups of two samples
C₃² = number of ways to choose which 2 samples will be tasted
[ as 2 samples × 3 cups each = 6 cups ]
C₉⁴ = Number of ways to choose 4 cups out of 9
=
Hence,
the correct answer is option (B) 5/14
