breast cancer in premenopausal women. They report a p-value of 0.058. PROPOSITION ONE: The results suggest a statistically significant association between broccoli consumption and reduced risk of breast cancer at the 5% significance level; PROPOSITION TWO: The results prove the null hypothesis at the 5% significance level.
a. PROPOSITION ONE is true and PROPOSITION TWO is true
b. PROPOSITION ONE is true and PROPOSITION TWO is false
c. PROPOSITION ONE is false and PROPOSITION TWO is true
d. PROPOSITION ONE is false and PROPOSITION TWO is false

Answer:

c. PROPOSITION ONE is false and PROPOSITION TWO is true

Step-by-step explanation:

In this question, we have that:

pvalue of 0.058

Significance level of 0.05

The pvalue is larger than the significance level, which means that there is no statistically significant association(Propostion One is false), and the null hypothesis is not rejected, that is, it is proved, so Proposition Two is true.

This means that the correct answer is given by option C.

From midnight to 2:00 am, the temperature rose 1.15°C each hour. If the temperature at 2:00 am was -2.7°C, what was the temperat
malfutka [58]

Answer: -5 degrees Celsius

Step-by-step explanation:

Temp at 2:00am = -2.7

2:00am is two hours after midnight

During that time the temperature has risen by 1.15 degrees every hour so has risen in total by:

1.15x2 = 2.3 degrees

-2.7-2.3=-5

It was -5 degrees at midnight

If EG=67, then EF=?<br> There is a picture below
ikadub [295]
If EG=67 we have (3x+7)+(5x-4)=67
let's simplify
67 = (3x + 7) + (5x - 4) \\ 67 = 8x + 3 \\ 64 = 8x \\  \frac{64}{8}  = x \\ 8 = x
now we know x is 8 we can use this to find EF
since EF=3x+7
3(8) + 7 = 24 + 7 = 31
so we have EF is 31!

Answer:

<u>Given function:</u>

  • f(x) = (-x + 2)(x + 1)(x +2)

<u>We can rewrite it as:</u>

  • f(x) = - (x - 2)(x + 1)(x +2)

<u>Zeros are:</u>

  • - (x - 2)(x + 1)(x +2) = 0
  • x - 2 = 0 ⇒ x = 2
  • x + 1 = 0 ⇒ x = -1
  • x + 2 = 0 ⇒ x = -2

As leading coefficient is negative the function is decreasing.

As the function is of degree 3, it is odd.

<u>Considering the above two factors we can define the shape of the graph:</u>

  • It is decreasing function with one local minimum and one local maximum.

<em>See the graph and zero's reflected.</em>
