Answer:

d.every word in the first sentence of the first page of every chapter.

Step-by-step explanation

the sample space means the set of total possible outcomes or ALL possible outcomes.

so here, the situation is about the teacher reading a sentence.

the favorable outcome is the set which has all the words that the students would not know from all the words read by the teacher or simply from the sample space.

since the teacher reads the first sentence on the first page in every chapter , all the words in that sentence will be sample in this situation.

What are the integer solutions to the inequality below?<br> <img src="https://tex.z-dn.net/?f=3%5Cleq%203x-4%5C%20%20%5Ctextless

Rudik [331]

Given:

The compound inequality is:

$3\leq 3x-4$

To find:

The integer solutions for the given compound inequality.

Solution:

We have,

$3\leq 3x-4$

Case 1: $3\leq 3x-4$

$3+4\leq 3x$

$\dfrac{7}{3}\leq x$

$2.33...\leq x$ ...(i)

Case 2: $3x-4$

$3x-2x$

$x$ ...(ii)

Using (i) and (ii), we get

$2.33...$

The integer values which satisfy this inequality are only 3 and 4.

Therefore, the integer solutions to the given inequality are 3 and 4.

Find the value of each variable using sine and cosine. Round your answers to the nearest tenth.

Alisiya [41]

Answer:

x ≈ 9.5 , y ≈ 15.3

Step-by-step explanation:

sin32° = $\frac{opposite}{hypotenuse}$ = $\frac{x}{18}$ ( multiply both sides by 18 )

18 × sin32° = x , then

x ≈ 9.5 ( to the nearest tenth )

cos32° = $\frac{adjacent}{hypotenuse}$ = $\frac{y}{18}$ ( multiply both sides by 18 )

18 × cos32° = y , then

y ≈ 15.3 ( to the nearest tenth )
