Answer:

13\dfrac{1}{4}\ inches

Step-by-step explanation:

To find the total length, you should add all lengths and calculate the sum. There are

3 buttons of length \frac{1}{4} inch

2 buttons of length \frac{3}{8} inch

4 buttons of length \frac{1}{2} inch

2 buttons of length \frac{5}{8} inch

3 buttons of length \frac{3}{4} inch

2 buttons of length \frac{7}{8} inch

2 buttons of length 1 inch

2 buttons of length 1\frac{1}{4} inches

Total length:

3\cdot \dfrac{1}{4}+2\cdot \dfrac{3}{8}+4\cdot \dfrac{1}{2}+2\cdot \dfrac{5}{8}+3\cdot \dfrac{3}{4}+2\cdot \dfrac{7}{8}+2\cdot 1+2\cdot 1\dfrac{1}{4}=\\ \\=\dfrac{3}{4}+\dfrac{3}{4}+2+\dfrac{5}{4}+\dfrac{9}{4}+\dfrac{7}{4}+2+2\cdot \dfrac{5}{4}=\\ \\=4+\dfrac{27}{4}+\dfrac{10}{4}=\\ \\=4+\dfrac{37}{4}=\\ \\=4+9\dfrac{1}{4}=\\ \\=13\dfrac{1}{4}

A poll was taken this year asking college students if they considered themselves overweight. A similar poll was taken 5 years ag
Katyanochek1 [597]

Answer:

At 5% significance level, it is statistically evident that    there is nodifference in the proportion of college students who consider themselves overweight between the two poll                                  

Step-by-step explanation:

Given that a poll was taken this year asking college students if they considered themselves overweight. A similar poll was taken 5 years ago.

Let five years ago be group I X and as of now be group II Y

H_0: p_x =p_y\\H_a: p_x \neq p_y

(Two tailed test at 5% level of significance)

                Group I            Group II              combined p

n                  270                 300                         570

favor            120                  140                          260

p                   0.4444            0.4667                   0.4561

Std error   for differene = \sqrt{\frac{0.4561(1-0.4561)}{570} } \\=0.0209

p difference = -0.0223    

Z statistic = p diff/std error =       -1.066

p value =0.2864

Since p value >0.05, we accept null hypothesis.

        At 5% significance level, it is statistically evident that    there is nodifference in the proportion of college students who consider themselves overweight between the two poll

The lowest point on the parabola is (0, -1).
astraxan [27]

Answer:

vertex

Step-by-step explanation:

vertex

If the coefficient a > 0, then the parabola opens upward and the vertex is the lowest point on the parabola. We say that k is the minimum value of the quadratic function. On the other hand, if the coefficient a < 0, then the parabola opens downward and the vertex is the highest point on the parabola.
