Study the following frequency distribution table.

m_a_m_a [10]

Answer:

Option C is correct.

f = 2

Step-by-step explanation:

The mean is the sum of variables divided by the number of variables

Mean = (Σfx)/(Σf)

xi | 15 | 17 | 20 | 30 | 10 + f

fi | 4 | 4 | 6 | 5 | 6

Σfx = (15×4) + (17×4) + (20×6) + (30×5) + [(10+f)×6] = 60 + 68 + 120 + 150 + 60 + 6f = (458 + 6f)

Σf = 4 + 4 + 6 + 5 + 6 = 25

Mean = 18.8

18.8 = (458+6f) ÷ 25

458 + 6f = 25 × 18.8 = 470

6f = 470 - 458 = 12

f = (12/6) = 2

Hope this Helps!!!

Andre and Elena are each saving money. Andre starts with $100 in his savings account and adds $5 per week. Elena starts with $10

Tomtit [17]

Answer:

Andre have more money after 4 weeks and after 6 week they have same amount of money.

Step-by-step explanation:

When Andre =100 then Elena =10.

After 4 week,

Andre = 100+(5*4)=100+20=120

In this time Elena = 10+(20*4) =10+80 = 90

After more 2months Andre have more 5+5=10

Then his total balance will be 120+10=130.

Than Elena after 2 week have 20+20=40.

Then her total balance will be 90+40=130.

That's mean 4 weeks+ extra 2 weeks total 6 weeks

How long did it take to reach the bottom of the slope

mafiozo [28]

To solve this we are going to use the kinematic equation for final velocity: $V_{f}=V_{i}+at$
where
$V_{f}$ is the final velocity
$V_{i}$ is the initial velocity
$a$ is the acceleration
$t$ is the time

We know for our problem that the the velocity at the beginning of the slope is $2.0ms^{-1}$ , so $V_{i}=2.0$ . We also know that the speed ad the bottom of the slope is $20ms^{-1}$ , so $V_{f}=20$ . We also know that the acceleration is $6ms^{-2}$ , so $a=6$ . Lets replace those values in our formula and solve for $t$ :
$V_{f}=V_{i}+at$
$20=2+6t$
$6t=18$
$t= \frac{18}{3}$
$t=3$ seconds

We can conclude that it takes the roller coaster 3 seconds to reach the bottom of the slope.
