Answer:

The probability the Rams scored at least 20 points is 62.5%

Step-by-step explanation:

Data form histogram:

No. of points                        No. of games

0-9                                                 2

10-19                                              4

20-29                                            5

30-39                                            3

40-49                                            2

Now we are supposed to find the probability the Rams scored at least 20 points

So, we are supposed to find the probability the Rams scored 20 or more than 20

So, Total no. of games = 2+4+5+3+2=16

No. of games where score is 20 or more than 20 =5+3+2 = 10

So,  the probability the Rams scored at least 20 points = [tex]\frac{10}{16}=0.625[/tex]

So, the probability the Rams scored at least 20 points is 62.5%

Answer:

900 min = 15 hours

Step-by-step explanation:

when we convert the velocities of the ships into miles/ min we get

45mph = 45m/60min = 0.75m/min

36mph = 36m/60min = 0.6m/min

The equations determining the distances  of the ships from the port M (set at x=0) are

D1 = 0.75t (for 45mph ship)

D2 = 162 + 0.6(t-45) (for 36mph ship)

The solution to these equation lie at t= 900 minutes; therefore the two ships will meet 900 minutes after the departure of the first ship.

Answer:

y=27 when x=2

Step-by-step explanation:

y varies inversely as the cube of x

y=k(1/X^3)

y=1 when x=6

y=k(1/X^3)

1=k(1/6^3)

1=k(1/216)

k=1÷1/216

K=1×216/1

k=216

find y when x=2

y=k(1/X^3)

y=216(1/2^3)

y=216(1/8)

y=216/8

y=27

Sarra watched 80% of the show.

Step-by-step explanation:

12÷15×100

Answer:

80%

Step-by-step explanation:

You have to take the total number of TV show episodes and divide it by the amount the person watched, in this case 15/12. Next, you have to multiply the answer you get by 100, in this case 0.8*100, this leads you to move the decimal point two places to the right giving you 80%.

Many students seem puzzled by function notation well after it has been introduced, and ask “why can’t we just write

y = 3x instead of

f(x) = 3x ?”. To motivate the use of function notation and improve understanding, I advocate using multi-variable functions instead of single-variable functions in introducing this notation. My introduction usually proceeds something like this:

Answer:

The distance formula

Step-by-step explanation:

This was kind of vague, but I'll try my best.

You can use the distance formula! It is basically the pythagorean theorem.

Here's the steps,

1. draw a right triangle from the corners. If you have graph paper, this should be relatively easy.

2. locate the hypotenuse, that is the distance.

3. next use the pythagorean theorem/ distance formula (same thing)

4. Except, instead of a and b and c, replace them with

(Change in x)²+(change in y)²= distance²

Now plug in the values

Now you're done!

Step-by-step explanation:

Answer:

Dr Khan will add 5 liters of 20% acetic acid solution.

Step-by-step explanation:

Dr Khan is combining two solutions of acetic acid with the given concentrations of 20% and 60% respectively.

Let the amount of 20% acetic acid, he added to get 10 liters of 40% solution = 'a' liters

Volume of 60% solution used will be = (10 - a) liters

Now the equation will be,

Amount of solution (1) × 20% + Amount of solution (2) × 60% = Amount of final solution × 40%

[tex]a\times \frac{20}{100}+(10-a)\times \frac{60}{100}=10\times \frac{40}{100}[/tex]

20a + 60(10 - a) = 400

20a + 600 - 60a = 400

600 - 40a = 400

40a = 600 - 400

a = [tex]\frac{200}{40}[/tex]

a = 5 liters

Therefore, Dr Khan will add 5 liters of acetic acid to get 40% acetic acid solution.

Solution:

Let the amount of 20% acetic acid, he added to get 10 liters of 40% solution = 'a' liters

Volume of 60% solution used will be = (10 - a) liters

Equation will be,

Amount of solution (1) × 20% + Amount of solution (2) × 60% = Amount of final solution × 40%

a*20/100+(10-a)*60/100=10*40/100

20a + 60(10 - a) = 400

20a + 600 - 60a = 400  

600 - 40a = 400

40a = 600 - 400            

a=200/40

a = 5 liters

Thus, Dr Khan  need to create 5 liters of acetic acid to get 40% acetic acid solution.
