jake performed an experiment to find out which type of chocolate melts the fastest, milk chocolate or dark chocolate. He tested
antoniya [11.8K]

Answer:

The correct option is;

After 64 seconds, ABOUT HALF of the brands of milk chocolate ARE LIKELY to melt, and NONE of the brands of dark chocolate ARE LIKELY to melt

Step-by-step explanation:

Here we have  for the milk chocolate

Min = 29 s

Lower quartile Q₁ = 44 s

Median = 64 s

Upper quartile Q₂ = 93 s

Max = 129 s

For the dark chocolate

Min = 210 s

Lower quartile Q₁ = 237 s

Median = 259 s

Upper quartile Q₂ = 295 s

Max = 320 s

As seen from the values of the box plot, after the median time of 64 seconds which represents half of the test results of the milk chocolate about half of the brands of milk chocolate are likely to melt, while the dark brands only start to melt after 210 seconds.

Therefore the correct option is

After 64 seconds, ABOUT HALF of the brands of milk chocolate ARE LIKELY to melt, and NONE of the brands of dark chocolate ARE LIKELY to melt.

Make a frequency distribution and find the relative frequencies for the following number set. Round the relative frequency to th
Pani-rosa [81]

Solution: We have to find the Frequency and Relative frequency of the given data:

Frequency is the number of times a number occurs.

Relative Frequency is the number of times a number occurs divided by the total number of items.

Therefore, the frequency and relative frequency are calculated as below:

Number       Frequency          Relative Frequency

20                       1                     \frac{1}{31} \times 100 =3.2\%

21                        4                    \frac{4}{31} \times 100 =12.9\%

22                       2                    \frac{2}{31} \times 100 =6.5\%

23                       4                    \frac{4}{31} \times 100 =12.9\%

24                       3                    \frac{3}{31} \times 100 =9.7\%

25                       2                    \frac{2}{31} \times 100 =6.5\%

26                       3                    \frac{3}{31} \times 100 =9.7\%

27                       5                    \frac{5}{31} \times 100 =16.1\%

28                       3                    \frac{3}{31} \times 100 =9.7\%

29                       4                    \frac{4}{31} \times 100 =12.9\%

Total                  31

Find the value or values of the Y in the quadratic equation y squared + 4 y + 4 equals 7
QveST [7]
Y² + 4y + 4 = 7
             - 7  - 7
 y² + 4y - 3 = 0
               y = -(4) ± √((4)² - 4(1)(-3))
                                   2(1)
               y = -4 ± √(16 + 12)
                                 2
               y = -4 ± √(28)
                            2
               y = -4 ± 2√(7)
                            2
               y = -2 ± √(7)
               y = -2 + √(7)    U    y = -2 - √(7)

The graph below represents Function R
Phoenix [80]

Option A: The rate of change of Function R is less than the rate of change of Function S because \frac{2}{3} is true.

Explanation:

The function S=3x-1

The equation for function R can be determined using the slope formula,

y=mx+b

The y-intercept is the value of y, when x = 0.

Thus, the y-intercept is b=1.

To determine the slope, let us substitute the coordinates (0,1) and (3,3).

Because, the points on the straight line have the same slope.

Thus, we have,

m=\frac{y_2-y_1}{x_2-x_1} \\m=\frac{3-1}{3-0} \\m=\frac{2}{3}

Thus, m=\frac{2}{3} and b=1

Let us substitute these values in the formula y=mx+b, we get,

y=\frac{2}{3} x+1

Hence, the equation of R is y=\frac{2}{3} x+1

The equation of S is y=3x-1

Comparing the slope of these two equations, we have,

\frac{2}{3}

This means that the slope of R is less than the slope of S.

Hence, The rate of change of Function R is less than the rate of change of Function S because \frac{2}{3}

Thus, Option A is true.
