Hello Kid!

The better estimate for the height of a desk is a meter, 1 meter, a kilometer is .62 of a mile...therefore they are way too big of unit of measurements.
Hope this helps!

elena-14-01-66 [18.8K]

Answer:

10.75

11

Step-by-step explanation:

the mean is the average, so add up all of the values and divide by 8 because there are 8 values :

(11 + 17 + 14 + 11 + 4 + 7 + 11 + 11)/8 = 10.75

the median is the middle value when the numbers are written in ascending or descending order :

4, 7, 11, 11, 11, 11, 14, 17

we can cross out the values on the ends, to get to the middle. if we do this, we are left with 11, 11

find the average of these numbers :

which is 11.

Elan Coil [88]

Answer:

13. 9.77 inches (rounded to 3 s.f.)

14. 249m² (rounded to 3 s.f.)

Step-by-step explanation:

13. To find the arc length, the formula is the angle of the arc out of 360° multiplied by the circumference of the full circle. Circumference of circle: pi × r × 2

\frac{80}{360} × pi × 7 × 2 = 3\frac{1}{9}pi

                       = 9.77 inches (rounded to 3 s.f.)

14. To find the sector area, the formula is the angle of the sector out of 360° multiplied by the area of the full circle. Area of circle: pi × r × r

\frac{285}{360} × pi × 10 × 10 = 79\frac{1}{6}pi

                          = 249m² (rounded to 3 s.f.)

Answer: 136 units squared

Step-by-step explanation:

I will assume this is a rectangular prism since it isn't specified.

The surface area of a rectangular prism: SA = 2(lw+lh+wh).

Plugging in your dimensions: SA = 2(7*2 + 7*6 + 2*6) = 2(14+42+12) = 2(68) = 136 units squared.

Determine the next three terms in the following sequence: 2, 3, 5, 8, ____, ____, ____,... a. 13, 19, 26 b. 12, 17, 23 c. 12, 16
Olenka [21]

Answer:

B. 12,17,23

Step-by-step explanation:

2,3,5,8, _,_,_

2,3 is increased by 1

3,5 is increased by 2

5,8 is increased by 3.  theres our pattern, each time it increases it follows the next number so the next 3 numbers it would be increased by is. 4,5,6.

Now knowing it is 4,5,6 we need to add, start adding.

8+4=12. Which answers have 12 in them? B and C.

We know 12 is the next number, now we add 5 to that.

12+5=17.

B has 17 but C doesn't, so that tells you its most likely going to be B. To make sure add 6 to 17.

17+6=23. Its true that it is B, as B is 12.17.23.
