The answer is 4. A function cannot have the same x value twice- 1 has two (2), 2 has all (1), 3 has two (-3), so 4 is the only answer.

The rectangle has an area of x to the second power plus 13x + 36 sq.Meters and a length of x + 9 meters. What expression represe
elena-s [515]

Answer: the expression for the width is x + 4

Step-by-step explanation:

The area of the rectangle is expressed as

Area = x² + 13x + 36 square meters.

The length is expressed as

L = x + 9 meters

To determine the expression for the width of the rectangle, we would factorize the expression for the area. Hence

x² + 13x + 36 = 0

We would find two numbers such that their sum or difference is 13x and their product is 36x². The two numbers are 9x and 4x. Therefore,

x² + 9x + 4x + 36 = 0

x(x + 9) + 4(x + 9) = 0

(x + 4)(x + 9)

Therefore, the expression that represents the width of the rectangle is x + 4

ABCD IS A TRAPEZIUM <br><br> WORK OUT THE SIZE OF ANGLE CDA.
zvonat [6]

Answer:

The measure of angle CDA is 27.6\°

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle ABF

Applying Pythagoras Theorem

A.F^{2}=6.5^{2}-6^{2}

A.F^{2}=6.25

A.F=2.5\ cm

In the right triangle CED

CE=6\ cm

ED=23-(9+2.5)=11.5\ cm

so

tan(

substitute the values

tan(

The average survival time after diagnosis for a certain type of cancer on the standard treatment is two years. A medical researc
wolverine [178]

Answer:

The sample size is too small

Step-by-step explanation:

The answer is the last one: the sample size is too small. Since we only got 3 subjects to test, maybe one of them could live for a long time after the diagnosis of Cacer and that made the average survival time go up by a lot.

In order to obtain results with a significance level higher, you need a sample size of at least 20 subjects.

Now lets see why other options wouldnt be good answers:

  • For a small amount of subjects, it is unlikely to have errors in caculation
  • The sample size is given
  • We are not given information about the treatment and we dont even know if the subjects feel more confident with the new treatment. Also, if a Placebo effect works regularly, it shouldnt limit statistical sifgnificance
  • An increase in 2 years is huge in comparison with the previous survival time.
