Answer:

A function is shown where b is a real number. f(x)=x^2+bx+144 The minimum value of the function is 80. Create an equation for an equivalent function in the form f(x)=(x-h)^2+k.

What is the location of the point on the number line that is 2/5 of the way from A = -6 to B = 9

sammy [17]

The distance between is =|9|+|-6|=15.
We can find that
$\frac{2}{5} \times 15 = 6$
So 2/5 of the AB segment is 6 distance points away from A at point C=0.

Use the figure to find the measurements of the numbered angles

sineoko [7]

Angle 1 would 107° since a and b are parallel. Angle 2 would be 180° - 107° = 73°.

Perform the indicated operation. 10 3/7 + 19 5/9

DanielleElmas [232]

Given expression is

$10 \frac{3}{7} + 19 \frac{5}{9}$

Now convert mixed fraction as improper fraction as

$10 \frac{3}{7} + 19 \frac{5}{9} = \frac{10*7 + 3}{7} + \frac{19*9+5}{9}$
                                                         $= \frac{73}{7} + \frac{176}{9}$
                                                          $= \frac{73*9 + 176 * 7}{63}$
                                                         $= \frac{657 + 1232}{63} = \frac{1889}{63}$
Now we can convert $\frac{1889}{63 } = 29 \frac{62}{63}$

So the answer is $29 \frac{62}63}$

Select the correct answer. Twenty students in Class A and 20 students in Class B were asked how many hours they took to prepare

Lunna [17]

Answer:

B: The mean study time of students in Class B is less than students in Class A.

Step-by-step explanation:

To find out why answer B is the right answer, I will give you facts from each option.

Option A is false. The mean study time in Class A is 4.8. Meanwhile in Class B it is 4. For Class A, sum up the 20 study times which is 96 and divide them by 20, you will get 4.8 hours of mean study time. For Class B, the sum of the 20 study times is 80, which divided by 20 will be 4.

Option B is True. See previous explanation.

Option C is False. The median study time in Class B is 4. The median study time in Class A is 4.8,

Option D is False. The range in Class A is from 2 to 8. The range in Class B is from 2 to 7.

Option E is False: The mean and median study time of these classes is different.
