A box has a total surface area of $100.$ The length of the box is equal to twice its width, as well as equal to $3$ less than it
CaHeK987 [17]

Answer:

Formula:  width x depth x height

Step-by-step explanation:

times 100 and 3. As we know that the formula for a box is  width x depth x height.

We need to measure the box from all side so 4 sides. so times the 2 number by 2 cause there is 4 sides each.

Hope this helps

ale4655 [162]

Answer: 4/5 of a box of candy

Step-by-step explanation:

Justine sold 1¹/₅ times the ²/₃ of a box of candy that Grayson sold.

Justin sold;

= 1¹/₅ * ²/₃

= 6/5 * 2/3

= 12/15

= 4/5 of a box of candy

Based on a research​ survey, when 1020 adults were asked about hand​ hygiene, 44% said that they wash their hands after using pu
aleksley [76]

Considering that the subjects are chosen without replacement, they are not independent, and the probability cannot be found using the binomial distribution.

The binomial distribution and the hypergeometric distribution are quite similar, as:

  • They find the probability of exactly x successes on n repeated trials.
  • For each trial, there are only two possible outcomes.

  • The difference is that the binomial distribution is for independent trials, that is, in each trial, the probability of success is the same, while the hypergeometric distribution is for dependent trials.
  • If the sample is without replacement, the trials are not independent, thus the hypergeometric distribution is used, not the binomial.

Which of the following expression expressions is equivalent to cos3x/sinxcosx?
77julia77 [94]
Correct Option:
Option B

Solution:
The given expression is:

\frac{cos(3x)}{sin(x)cos(x)}

cos(3x) can be written as cos(2x +x). Expanding it, we get:

cos(3x) = cos(2x+x) \\  \\ 
cos(3x) =cos(2x)sin(x)-sin(2x)cos(x)

Using this value of cos(3x) in given equation, we get:

\frac{cos(3x)}{sin(x)cos(x)} \\  \\ 
= \frac{cos(2x)sin(x)-sin(2x)cos(x)}{sin(x)cos(x)} \\  \\ 
= \frac{cos(2x)sin(x)}{sin(x)cos(x)}- \frac{sin(2x)cos(x)}{sin(x)cos(x)}  \\  \\ 
= \frac{cos(2x)}{cos(x)} - \frac{sin(2x)}{sin(x)} \\  \\ 
=sec(x)cos(2x)-csc(x)sin(2x)

In June, Meg runs a race 10 seconds faster than she did in April. Let y represent her finishing time for the race in April. Whic
Marina CMI [18]
Answer: The expression that represents Meg's finishing time in June is "y - 10".

The problem started with Meg running in April. She had a time in April and we called it "y".

Now, Meg ran again in June. In June, she did 10 seconds faster. So it makes since that we need to subtract 10 from her April time, "y". Therefore, the expression is simply "y - 10".
