Answer:

Step-by-step explanation:

The gray shadowed area is below descending function and the line is dashed.

It means<u> coefficient x is m<0</u> and the sign of inequality is y <

So the inequality wich fit it is <u>y < -1/2x + 2</u>

The blue shadowed area is above ascending function and the line is uninterrupted.

It means<u> coefficient x is m>0</u> and the sign of inequality is y ≥

So the second inequality of system (<u>y ≥ 3x - 1)</u> also match.

109 seals

Step-by-step explanation:

Let

x -----> approximate total seals in the area

we know that

In a survey, you count 58 seals, 16 of which were marked

Using proportion

Find out how many seals are in the area , if there are 30 marked seals

$\frac{58}{16} =\frac{x}{30}\\\\x=58(30)/16\\\\x=108.75\ seals$

Round to the nearest whole number

$108.75\ seals=109\ seals$

Exercise 2

nadezda [96]

Answer:

a) 0.72

b) 0.98

Step-by-step explanation:

We are given the following information in the question:

P(passing maths exam) = P(m) = 0.9

P(passing Spanish exam) = P(s) = 0.8

It is assumed that the results of the two exams are independent of each other.

a) probability that she passes both exams

By assumption of independence, we can write:

$P(\text{passes both exam} = P(M\cap S) \\=P(M)\times P(S) = 0.8\times 0.9 = 0.72$

0.72 is the probability that Josie will pass both the exams.

b) probability that Josie passes at least one of the exam

$P(\text{at least one of the exams}) = P(M\cup S)\\= P(M) + P(S) - P(M\cap S)\\= 0.9 + 0.8 - 0.72 = 0.98$

0.88 is the probability that Josie passes at least one of the exams.
