Jlenok [28]

Answer: 174 red chips

Step-by-step explanation:

A bag contains a total of 300 red chips and white chips. A student chooses a chip out of the bag, then records the color, and places the chip back in the bag. By doing this, the student recorded 29 red chips and 21 white chips.

To predict the number of red chips in the bag using this method goes thus:

Number of red chips picked= 29

Number of white chips picked= 21

Total number of chips= 29+21 = 50

So, the student picked 29/50. Out of 300 chips, number of reds that will be picked will be:

= 29/50 × 300

= 29 × 6

= 174 red chips

Citrus2011 [14]

Answer:

the answer is option B

Step-by-step explanation:

To find dy/dx the equation here is

first multipled by derivative of second + second multipled by derivative of first

y = x*sinx

dy/dx = x * derivative of sinx + sinx * derivative of x

derivative of x with respect to x is 1

derivative of sinx with respect to x is cosx

therefore

dy/dx = x * cosx + sinx * 1

= x * cosx + sinx
