In a second period class, 37.5% of students like to bowl. in a fifth period class, 12 out of 29 students like to bowl. in which
Ierofanga [76]

The fifth period class has a greater fraction of students that like to bowl.

Any number in the form of p/q where p and q are integers and q is not equal to 0 is a rational number. Examples of rational numbers are 1/2, -3/4, 0.3, or 3/10.

Here we have,

In second period, 37.5% students like to bowl

∴, 37.5% = 37.5/100

= 375/1000

= 0.375 students like to bowl in second period

And in fifth period, 12 students out of 29 like to bowl

Therefore, 12/29 = 0.413 students like to bowl in fifth period

Hence, on comparison

0.375 < 0.413

= 375/1000 < 12/29

Thus, fifth period class has a greater fraction of student that like to bowl as compared to second period class.

Use the Remainder Theorem to find the remainder when P(x) = x^4 – 9x^3 – 5x^2 – 3x + 4 is divided by x + 3.
kirza4 [7]
P(x) = (x + 3)Q(x) + R 

<span> P(-3) = (0)Q(x) + R </span>

<span>i P(-3) = R </span>

<span>Now, P(-3) = (-3)⁴ - 9(-3)³ - 5(-3)² - 3(-3) + 4 
</span>So

<span>P(-3) = 81 + 243 - 45 + 9 + 4 </span>
<span>=. 292 
hope it helps</span>
