<h3><u>Question:</u></h3>

In a video game, Clare scored 50% more points than Tyler. If c is the number of points that Clare scored and t is the number of points that Tyler scored, which equations are correct? Select all that apply.

the options are

A. c=1.5t

B.c=t+0.5

C. c=t+0.5t

D. c=t+50

E.c=(1+0.5)t

<h3><u>Answer:</u></h3>

Options A, C, E are correct

The correct equations are c = 1.5t and c = t + 0.5t and c = (1 + 0.5)t

<h3><u>Solution:</u></h3>

Let "c" be the number of points clare scored

Let "t" be the number of points tyler scored

Given that,

Clare scored 50% more points than Tyler

Points scored by clare = points tyler scored + 50% of Tyler points

c = t + 50 % of t

Therefore, on solving, we get

c = t + \frac{50}{100} \times t\\\\c = t + 0.5t

Thus option c is correct

On simplfying we get,

c = t + 0.5t = 1.5t

c = 1.5t

Thus option A is correct

c = t + 0.5t

On taking "t" as common we get,

c = t(1 + 0.5)

Thus option E is also correct

How quickly do synthetic fabrics such as polyester decay in landfills? A researcher buried polyester strips in thes oil for diff
ad-work [718]

Answer:

no enough evidence to draw up a conclusion

Step-by-step explanation:

Data:

let: \mu _{1} = decay after 2 weeks

    \mu _{2} = decay after 16 weeks

Making the hypotheses:

Null hypothesis; H_{o} = \mu _{1}  - \mu _{2} = 0

the deviation = 0.05

the standard difference  = 4

Conditions:

The normal distribution curve can be plotted on a graph and the plot shows that the distribution is a skewed distribution.

Then,

t = \frac{(123.8-16.4)-0}{\sqrt{\frac{4.6^{2} }{5}+\frac{16.09^{2} }{5}   } } \\  = 0.989

Therefore, it can be concluded that 0.1983 > 0.05. This presents our failure to reject the null hypothesis.

Thus, there is not enough evidence to conclude that polyester decays more in less than 2 weeks.

Answer:

Last option: increasing: -2 < x < 0 and x> 3/2;

decreasing: x < -2 and 0 < x < 3/2

Step-by-step explanation:

The function given is an absolute cubic function. (Pictured below).

We can determine from the graph that the equation increases over the interval:

increasing: -2 < x < 0 and x> 3/2;

decreasing: x < -2 and 0 < x < 3/2
