mestny [16]

Percentage of Lemonade = 100 - (15 + 5)
= 100 - 20 = 80%

Now, We have to calculate the 80% of total amount of the drink i.e., 300 ml

So, 300 * 80%
= 300 * 0.80 [ 80% = 0.80 ]
= 240

In short, Your Answer would be: 240 ml

Hope this helps!

6+6x + 6x = - 42 <br> what x equals

ankoles [38]

Answer:

x = -4

Step-by-step explanation:

Add like terms:

6 + 6x + 6x = -42

12x + 6 = -42

Subtract 6 from both sides:

12x = -48

Divide each side by 12:

x = -4

Which equation, when graphed, has x-intercepts at (2, 0) and (4, 0) and a y-intercept of (0, â€"16)? f(x) = â€"(x â€" 2)(x â€" 4

zmey [24]

To find the equation, for the x-intercepts at (2, 0) and (4, 0) and a y-intercept of (0, –16) we have to find the nature of the curve.

The correct option is f(x) = –2(x – 2)(x – 4).

Given:

The x-intercepts at (2, 0) and (4, 0).

The y-intercept of (0, –16).

The nature of the graph is quadratic curve. Write the general equation for x-intercept.

$y=a(x-2)(x-4)$

Where is $a$ number

Substitute 0 for $x$ .

$y=a(0-2)(-4)\\y=8a$

We have y-intercept of (0, –16).

$-16=8a\\a=-2$

The equation would be,

$f(x) = -2(x - 2)(x - 4).$

Thus, the correct option is f(x) = –2(x – 2)(x – 4).

each of the 20 balls is tossed independently and at random into one of the 5 bins. let p be the probability that some bin ends u

amm1812

if p is the probability that some bin ends up with 3 balls and q is the probability that every bin ends up with 4 balls. pq is 16.

First, let us label the bins with 1,2,3,4,5.

Applying multinomial distribution with parameters n=20 and p1=p2=p3=p4=p5=15 we find that probability that bin1 ends up with 3, bin2 with 5 and bin3, bin4 and bin5 with 4 balls equals:

5−2020!3!5!4!4!4!

But of course, there are more possibilities for the same division (3,5,4,4,4) and to get the probability that one of the bins contains 3, another 5, et cetera we must multiply with the number of quintuples that has one 3, one 5, and three 4's. This leads to the following:

p=20×5−2020!3!5!4!4!4!

In a similar way we find:

q=1×5−2020!4!4!4!4!4!

So:

pq=20×4!4!4!4!4!3!5!4!4!4!=20×45=16

thus, pq = 16.
