Solve the proportion and round your answer to the nearest tenth.

GalinKa [24]

Answer:

y = 1.1

Step-by-step explanation:

Proportion is a statement that two ratios are equal.

It can be written in two ways:

Two equal fractions $\frac{a}{b}$ = $\frac{c}{d}$

Two equal sides a: b = c: d.

We can use cross products to find a missing term in it.

Let us solve the question

∵ The proportion statement is $\frac{7.7}{15.4}$ = $\frac{y}{2.2}$

→ Use the cross multiplication to find y

∵ y × 15.4 = 7.7 × 2.2

∴ 15.4y = 16.94

→ Divide both sides by 15.4 to find y

∵ $\frac{15.4y}{15.4}$ = $\frac{16.94}{15.4}$

∴ y = 1.1

<em>No need to round it to the nearest tenth because the answer has no hundredth to round it to the tenth</em>

If f(x) -V7-3, complete the following statement (round your answer

nikklg [1K]

Answer:

- 1.67

Step-by-step explanation:

f(x) = $\frac{3}{7+2}$ - $\sqrt{7-3}$

= $\frac{3}{9}$ - $\sqrt{4}$

= $\frac{1}{3}$ - 2

= - 1 $\frac{2}{3}$

= -1.6666666

= -1.67

In a large statistics course, 74% of the students passed the first exam, 72% of the students pass the second exam, and 58% of th

11111nata11111 [884]

Answer:

Required probability is 0.784 .

Step-by-step explanation:

We are given that in a large statistics course, 74% of the students passed the first exam, 72% of the students pass the second exam, and 58% of the students passed both exams.

Let Probability that the students passed the first exam = P(F) = 0.74

Probability that the students passed the second exam = P(S) = 0.72

Probability that the students passed both exams = $P(F \bigcap S)$ = 0.58

Now, if the student passed the first exam, probability that he passed the second exam is given by the conditional probability of P(S/F) ;

As we know that conditional probability, P(A/B) = $\frac{P(A\bigcap B)}{P(B) }$

Similarly, P(S/F) = $\frac{P(S\bigcap F)}{P(F) }$ = $\frac{P(F\bigcap S)}{P(F) }$ {As $P(F \bigcap S)$ is same as $P(S \bigcap F)$ }

= $\frac{0.58}{0.74}$ = 0.784

Therefore, probability that he passed the second exam is 0.784 .
