Answer:

The new weight-loss supplement was more effective on females in the study because only 85% of them failed to lose weight after two weeks, 15% of the females whereas failed to lose weight after two weeks.

Step-by-step explanation:

Male proportion that lose weight

p_m=38/50=0.76

Female proportion that lose weight

p_f=85/100=0.85

Proportion of females that failed to lose weight

p_{f2}=1-0.85=0.15

Answer:

Step-by-step explanation:

Males proportion who did not lose weight = 12/50 = 24%

Females proportion who did not lose weight = 15/100 = 15%

Thus we find this was effective for females compared to males.

he new weight-loss supplement was more effective on females in the study because only 15% of them failed to lose weight after two weeks, whereas 24% of the males failed to lose weight after two weeks.

So answer is Females, 15 and 24.

Find each value.Use a calculator is needed P(9,2) .P(5,5). P(7,7)
Andrews [41]
The answers are:
P(9, 2) = 72
P(5, 5) = 120
P(7, 7) = 5040

These are examples of permutations. The problems are asking us to find the total number of ways an event can happen.

In the first case, P(9, 2), we are asked to find the ways that 2 things can be chosen out of a group of 9.
9 x 8 = 72

P(5, 5) = 5 x 4 x 3 x 2 x 1 
P(7, 7) =  7 x 6 x 5 x 4 x 3 x 2 x 1

write an equation in slope intercept form for the line that passes through (4, -4) and is parallel to 3x+4x=2y-9
photoshop1234 [79]

Answer:

\large\boxed{y=\dfrac{7}{2}x-18}

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

Convert the equation of a line 3x + 4x = 2y - 9 to the slope-intercept form:

3x+4x=2y-9

7x=2y-9             <em>add 9 to both sides</em>

7x+9=2y       <em>divide both sides by 2</em>

\dfrac{7}{2}x+\dfrac{9}{2}=y\to y=\dfrac{7}{2}x+\dfrac{9}{2}

Parallel lines have the same slope. Therefore we have the equation:

y=\dfrac{7}{2}x+b

Put the coordinates of the point (4, -4) to the equation:

-4=\dfrac{7}{2}(4)+b

-4=7(2)+b

-4=14+b       <em>subtract 14 from both sides</em>

-18=b\to b=-18

Finally we have the equation:

y=\dfrac{7}{2}x-18

Find x. Give reasons to justify your solution. b Lines AB and CD are straight lines.
MArishka [77]

Answer:

x = 28

Step-by-step explanation:

Given that lines AB and CD are straight lines that intersects at O, it follows that the pair of opposite vertical angles formed are congruent.

Thus,

<AOD = <BOC

<AOD = 152°

<BOC = 3x + x + (x + 12) (angle addition postulate)

<BOC = 5x + 12

Since <AOD = <BOC, therefore,

152° = 5x + 12 (substitution)

152 - 12 = 5x (subtraction property of equality)

140 = 5x

140/5 = x (division property of equality)

28 = x

x = 28
