Answer:

Step-by-step explanation:

The interquartile range is the middle 50% of the data.

To find the interquartile range, we must first find the lower and upper quartiles.

In this case, the lower quartile is 76.5, and the upper quartile is 94.5.

Subtracting 76.5 from 94.5 gives us the answer of 18.

Let me know if this helps!

Which of the expressions are equivalent to the one below? 5x(3+7)

MArishka [77]

3×(2+6)+4×5 is/= 44,

3×2+3×6+4×5=44

5×4+3×(6+2)=44

(6+2)×3+4×5=44

3×2+(6+4)×5= 56

So your answers are A, B, and C.

jerry is a judge. He hears 5 cases every 2 3/8 hours. Jerry hears caese at a constant rat. How many cases does he hear per hour

faust18 [17]

Answer:

The number of cases heard by Jerry per hour is $2\frac{21}{500}$

Step-by-step explanation:

The rate of hearing the cases is 5 cases in 2 3/8 hours.

Now, $2\frac{3}{8} = 2+\frac{3}{8} = 2 + 0.375 = 2.375$

⇒The judge hears 5 cases in 2.375 hours.

So, the number of cases per hour = $= \frac{\textrm{Total Number of cases heard}}{\textrm{Number of Hours}} = \frac{5}{2.375}$

= 2.105

Also, $2.105 = 2 + 0.105 = 2 + \frac{105}{1000} = 2+\frac{21}{500} = 2\frac{21}{500}$

Hence, the number of cases heard by Jerry per hour is $2\frac{21}{500}$

Answer:

7. -

a. 3.5 or 7/2 hours

b. 24.5

c. After 7 hours (and at the beginning when t=0)

8. -

a. 4 seconds

b. 1 second

c. 54 meters

Step-by-step explanation:

7. M(t)=-2t^2+14t

M’(t)=-4t+14

-4t+14=0

4t=14

2t=7

t=7/2

b) M(7/2)=24.5

M(t)=0

-2t^2+14t=0

t^2-7t=0

t(t-7)=0

t=0, 7

h(t)=0

-6t^2+12t+48=0

t^2-2t-8=0

(t-4)(t+2)=0

t=-2, 4

t=4

h(t)=-6t^2+12t+48

h’(t)=-12t+12

h’(t)=0

-12t+12=0

12t=12

t=1

c) h(1)=54
