A test consists of six

1 answer:

5 0

True/false questions grant a 50% chance for each question. If there are 6 questions, the probability of getting 3 right is 50%. You can find the answer by multiplying the percentages for each outcome.

50% × 50% = 25%

The student ultimately has a 25% chance of getting 3 of the 6 true/false questions correct.

Find the areas of the trapezoids

Sholpan [36]

Answer:

12 units²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = $\frac{1}{2}$ h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 4 ( perpendicular distance between the bases ) and

b₁ = SR = 2, b₂ = TA = 4 , then

A = $\frac{1}{2}$ × 4 × (2 + 4) = 2 × 6 = 12 units²
