Answer:

50 cm² and 56 cm²

Step-by-step explanation:

The area (A) is calculated as

A = $\frac{1}{2}$ × d₁ × d₂ ( d₁ and d₂ are the length of the diagonals )

(2)

A = $\frac{1}{2}$ × (8 + 2) × (5 + 5)

= 0.5 × 10 × 10

= 5 × 10

= 50 cm²

(3)

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

= 0.5 × 14 × 8

= 7 × 8

= 56 cm²

The picture that does not contain enough information to prove that ΔABC = ΔDEF is

(3) Picture (3)

Step-by-step explanation:

The given information in picture (3) is the Angle-Side-Side of ΔABC corresponds with the Angle-Side-Side of ΔDEF,

However, the condition of Angle-Side-Side of ΔABC, is not sufficient to prove that ΔABC is congruent to ΔDEF congruency because the length of the unknown side can have two possible values

From a large number of actuarial exam scores, a random sample of scores is selected, and it is found that of these are passing s

Mnenie [13.5K]

<u>Supposing 60 out of 100 scores are passing scores</u>, the 95% confidence interval for the proportion of all scores that are passing is (0.5, 0.7).

The lower limit is 0.5.
The upper limit is 0.7.

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $\alpha$ , we have the following confidence interval of proportions.
