Answer: 360minutes

Step-by-step explanation:

Speed = space/time ; time = space/speed

space = 600km

speed: 100km/h

time = 600km/100km/h = 6hours

Since 1hour = 60minutes

6hours = 6x60minutes = 360 minutes

Answer: 360minutes

3(2+7) - 9 x 7 = 3+8 x 2 x 2 - 4 = 16 ÷ 2 x 5 x 3 ÷ 6 = Please answer! ✨✨
Thepotemich [5.8K]

Answer:

At first, we have 3 expressions that are equal.

3(2+7) - 9 \cdot 7= 3+8 \cdot 2 \cdot 2 - 4

6+21 - 63= 3+32 - 4

-36=31

-36\neq 31

This is not true.

A sample of small bottles and their contents has the following weights (in grams): 4, 2, 5, 4, 5, 2, and 6. What is the sample v
Inessa05 [86]

Answer:

What is the sample variance of bottle weight 2.33

Step-by-step explanation:

First find the mean. The mean of the bottle weight is obtained by taking the ratio of the sum of ages and total number of ages.

Mean = (4+2+5+4+5+2+6) / 7

          = 28 / 7

          = 4

Sample Variance = \frac{\left[\begin{array}{ccc}(4-4)^{2} +(2-4)^{2} +\\(5-4)^{2} + (4-4)^{2} +\\(5-4)^{2} + (2-4)^{2} +\\(6-4)^{2}\end{array}\right]}{7-1}

                             =\frac{0+4+1+0+1+4+4}{6}

                             = 2.33
