masha68 [24]

Answer:

A. 2⅓ and D.1

Step-by-step explanation:

We are required to select the values of x that makes the inequality x>½ true.

A. 2⅓

B. 0

C.-1½

D. 1

E.-¾

Options C and E are negative numbers and are therefore less than the positive number ½.

Option B(i.e. 0) is also less than ½ or 0.5 and therefore do not satisfy the inequality given.

2) A bike racer completed a 20.0 kilometer race. She pedaled the first 5.0 kilometers with an average speed of 20.0 km/hr. She p

MakcuM [25]

Answer:

Step-by-step explanation:

Time = distance/speed

Considering the first stage,

Speed = 20km/hr

Distance = 5km

Time = 5/20 = 0.25 hour

Considering the second stage,

Speed = 10km/hr

Distance = 5km

Time = 5/10 = 0.5 hour

Considering the third stage,

Speed = 25km/hr

Distance = 5km

Time = 5/25 = 0.2 hour

Considering the third stage,

Speed = 20km/hr

Distance = 5km

Time = 5/20 = 0.25 hour

Therefore, the time it took the biker to complete the race is

0.25 + 0.5 + 0.2 + 0.25 = 1.2 hours

Answer:

Step-by-step explanation:

1) Find the Mean of all the numbers.

3+4+5+7+10+12+15=56

56/7=8 mean is 8

Now We Calculate Standard Deviation:

S= $\sqrt{(3-8)^2+(4-8)^2+(5-8)^2+(7-8)^2+(10-8)^2+(12-8)^2+(15-8)^2}$

You take each number from the problem i.e 3,4,5...

and then you subtract the mean from it and then square it.

S= $\sqrt{(-5)^2+(-4)^2+(-3)^2+(-1)^2+(2)^2+(4)^2+(7)^2}$

S= $\sqrt{25+16+9+1+4+16+49}$

S= $\sqrt{120}$

S= $\sqrt{120}/7$

7 is the amount of data units given in the problem.

120/7=17.1428571429

$\sqrt{17.1428571429}$ =4.1403933560541
