Answer:
plz mark the brainliest plzz
Weights of other two children = 36 kg and 30 kg
What is ratio?A ratio can be defined as the relationship or comparison between two numbers of the same unit to check how bigger is one number than the other one.
Given,
Ratio of weight of three children = 6:5:4
Weight of lightest child = 24kg
Let the common factor of the ratio is x
then ratio = 6x:5x:4x
4x is weight of lightest child
4x = 24kg
x = 24/4
x = 6kg
then weight of other two children
= 6x and 5x
= 6(6) and 5(6)
= 36kg and 30kg
Hence, 36 kg and 30 kg are the weights of other two children.

The answer would be 30 because the triangle is 10, the circle is 5, and each black triangle is 2 which would be 10 plus 5 which is 15 then times 2 which is 30.
Answer:
20?
Step-by-step explanation:
If 3 triangles = 30 they we could assume that each triangle = 10
10 + 10 + 10 = 30
If one triangle = 10 then the 2 circles would = 5 in the 2nd equation
10 + 5 + 5 = 20
If 1 circle = 5 then the 1 full squares would = 4
5 + 4 + 4 = 13
1 triangle = 10 , 1 circle = 5, Half a square = 2
10 + 5 * 2 = ?
Using PEMDAS we would multiply 2 and 5 first to get 10
10 + 10 = 20

Let x represent the regular price of the cell phone. Use the word bank below to complete each blank. [Click on the phrase to fill in the blank. You do NOT need to type.] A.] Suppose only the 20% discount applies. Find a function \large f\left(x\right) that models the purchase price of the cell phone. f(x)
Answers
Answer:
[tex]f(x) = 0.80x[/tex]
Step-by-step explanation:
Given
[tex]x \to price[/tex]
[tex]discount \to 20\%[/tex]
[tex]coupon = \$50[/tex]
Required
The function f(x) if only the discount applies
20% discount implies that the price will be reduced by 20%.
So, the function is:
[tex]f(x) = Price - Price * Discount[/tex]
[tex]f(x) = x - x * 20\%[/tex]
Factorize
[tex]f(x) = x(1 - 20\%)[/tex]
Express percentage as decimal
[tex]f(x) = x(1 - 0.20)[/tex]
[tex]f(x) = x(0.80)[/tex]
[tex]f(x) = 0.80x[/tex]

tell whether the given value is a solution of the inequality . 2n > 16; n=9
(please help with this question i will mark you brainliest! )
Answers
========================================================
Explanation:
Let's replace n with 9 to see if we get a true inequality or not.
2n > 16
2*9 > 16
18 > 16
We get a true statement since 18 is indeed larger than 16. Therefore, n = 9 is a solution.
------------
Here's another way to tackle the problem:
We can isolate n as if solving an equation. Divide both sides by 2 to do this. The inequality sign does not flip (it only does so if you divide both sides by a negative number).
So we get...
2n > 16
2n/2 > 16/2
n > 8
The solution set is any number larger than 8. Since n = 9 fits the description, that's one of the infinitely many solutions.
------------

Let XX be a random variable that is equal to the number of heads in two flips of a fair coin. What is \text E[X^2]E[X 2 ]
Answers
Answer:
Step-by-step explanation:
From the given information, it is likely that the random variable(X) have the values below:
Let head be H
Let tail be T
So;
X(HH) = 2;
X(HT) = 1;
X(TH) = 1;
X(TT) = 0
The distribution can now be computed as:
[tex]p(X= TT) = \dfrac{1}{4}[/tex]
[tex]p(X=TH) = \dfrac{1}{4}[/tex]
[tex]p(X=HT) = \dfrac{1}{4}[/tex]
[tex]p(X=HH)= \dfrac{1}{4}[/tex]
Now, the expected value that is equivalent to the number of heads when the coin is flipped twice is:
[tex]E(X) = p(TT)*X(TT)+p(TH)*X(TH)+p(HT)*X(HT)+p(HH)*X(HH)[/tex]
[tex]E(X) = \dfrac{1}{4}\times 0 + \dfrac{1}{4}\times 1 + \dfrac{1}{4}\times 1 + \dfrac{1}{4}\times 2[/tex]
[tex]E(X) = 0 + \dfrac{1}{4}+ \dfrac{1}{4} + \dfrac{1}{2}[/tex]
[tex]E(X) =\dfrac{1+1+2}{4}[/tex]
[tex]E(X) =\dfrac{4}{4}[/tex]
E(X) = 1
[tex]E(X^2) = p(TT)*X(TT)^2+p(TH)*X(TH)^2+p(HT)*X(HT)^2+p(HH)*X(HH)^2[/tex]
[tex]E(X^2) = \dfrac{1}{4}\times 0^2+ \dfrac{1}{4}\times 1^2 + \dfrac{1}{4}\times 1^2 + \dfrac{1}{4}\times 2^2[/tex]
[tex]E(X^2) = 0 + \dfrac{1}{4}+ \dfrac{1}{4} + \dfrac{4}{4}[/tex]
[tex]E(X^2) =\dfrac{1+1+4}{4}[/tex]
[tex]E(X^2) =\dfrac{6}{4}[/tex]
[tex]E(X^2) =1.5[/tex]
Finally; To compute E²[X]
E²[X] = E[X]²
E²[X] = 1²

Great Foods will soon begin producing a new line of puppy food. The marketing department predicts that the demand function will be D(p) = −14.99p + 985.27 and the supply function will be S(p) = 90.85p− 6.39
What price per unit should be charged in order to have equilibrium between supply and demand?
$___
Answers
======================================================
Explanation:
Equilibrium is reached when supply and demand are equal. So when D = S.
Let's solve for p
D = S
-14.99p+985.27 = 90.85p-6.39
-14.99p-90.85p = -6.39-985.27
-105.84p = -991.66
p = -991.66/(-105.84)
p = 9.36942554799698
p = 9.37
