Answer:
50
Step-by-step explanation:
Suppose that the kids get $x_1,x_2,x_3,x_4,x_4$ pieces of candy, respectively (each twin received $x_4$ pieces). Then we seek all quadruples $(x_1,x_2,x_3,x_4)$ satisfying
\[x_1+x_2+x_3+2x_4 = 6.\]We proceed by casework, based on the number of candies the twins receive.
If $x_4 = 0$, then there are 6 candies to distribute to 3 kids. This is like arranging 6 C's and 2 |'s (dividers), so there are $\binom{8}{2} = 28$ possible distributions.
If $x_4 = 1$, there are 4 candies remaining for the other 3 kids, so there are $\binom{6}{2} = 15$ possible distributions.
If $x_4 = 2$, there are 2 candies remaining, so there are $\binom{4}{2} = 6$ possible distributions.
If $x_4 = 3$, there are 0 candies remaining, for 1 possible distribution.
Adding all of these results from the separate cases, there are a total of
\[28 + 15 + 6 + 1 = \boxed{50}\].

Can people help with (5a), (5b), (5c), (6a), and (6b)
｡☆✼★ ━━━━━━━━━━━━━━ ☾
5a.
8x = 2/3
Divide by 8 on both sides
x = (2/3) / 8
x = 1/12
5b.
1.5 = 2x
Divide by 2 on both sides
x = 1.5 / 2
x = 3/4
5c.
5x = 2/7
Divide both sides by 5
x = (2/7) / 5
x = 2/35

What are the coordinates of the vertex of a parabola whose equation is y−4=2(x+7)2 ?
Question 5 options:
a) (7, -4)
b) (-7, 4)
c) (4, -7)
b) (-4, 7)
The coordinate of the vertex of the parabola y - 4 = 2(x+7)² is (-7,4)
The coordinate of the vertex?The equation of the parabola is given as:
y - 4 = 2(x+7)²
Add 4 to both sides
y = 2(x+7)² + 4
A parabola is represented as:
y = a(x- h)² + k
Where, the vertex is:
vertex = (h,k)
By comparison, we have:
Vertex = (-7,4)
Hence, the coordinate of the vertex is (-7,4)

Find the domain of the function.
y = [tex]\sqrt{x} + 1[/tex]
Answer:
[0, infinity)
Step-by-step explanation:
A square root can only use positive numbers, otherwise it becomes imaginary. A function needs to be real to output real values. Therefore, the domain is everything from 0 onwards.

In circle A shown below, the measure of ∠BAD is 148°: Circle A with angle BAD measuring 148 degrees; points B, C, D lie on Circle A. If m Arc BC is 96°, what is m Arc CD ?
Answer:
52°
Step-by-step explanation:
In the figure attached, Circle A is shown. There we can see that:
∠BC + ∠CD = ∠BAD
We know that Arc BC measures 96° and arc BAD measures 148°. Replacing this data into the equation and solving for Arc CD, we get:
96° + ∠CD = 148°
∠CD = 148° - 96°
∠CD = 52°
Answer:
The answer is 52

{(0, 3), (-2, 15), (4, 21)}
Answer:
{0, -3), (2, 9), (4, 21)}
Step-by-step explanation:
if x = 0 ⇒ y = 6x - 3 = 6(0) - 3 = 0 - 3 = -3
if x = 2 ⇒ y = 6x - 3 = 6(2) - 3 = 12 - 3 = 9
if x = 4 ⇒ y = 6x - 3 = 6(4) - 3 = 24 - 3 = 21

Consider triangle QRS. The legs each have a length of 10 units. What is the length of the hypotenuse of the triangle?
Answer:
14.14
Step-by-step explanation:
10^2+10^2=x^2
x=square root 200
Solution,
Hypotenuse=?
Perpendicular=10 units
Base=10 units
Using the Pythagoras theorem,
H^2=p^2+b^2
or,h^2= (10)^2+(10)^2
or,h^2=100+100
or,h^2=200
or,h=√200
h=10√2 or 14.14

Answer:
You would need $23.87.
Step-by-step explanation:
Divide $20.46 by 6 which equals $3.41. Multiply $3.41 by 7 and you get $23.87.
Answer:
You would need $23.87
Step-by-step explanation:
Cost for 6 books is 20.46
Finding the unit cost:
the cost of one single book will be amount for 6books ÷ 6
= 20.46 ÷ 6
= 3.41
We need to find the cost of 7 books so now that we know it for one book, we multiply that amount by 7
Therefore,
3.41 x 7
= 23.87 dollars
An isosceles triangle has two angle measurements of 80 and 50 degrees. Could more than one triangle be drawn that fits these conditions? Explain.
Answer:
Step-by-step explanation:
In an isosceles triangle, the base angles are equal. This also means that two sides of the triangle are equal in length. Since the sum of the angles in a triangle is 180 degrees, it means that the third angle of the given triangle is
180 - (80 + 50) = 50 degrees
Therefore, the base angles of the isosceles triangle are 50 degrees each. For more triangles with these conditions to be drawn, only the lengths of the equal sides can be increased or decreased. This would in turn increase the length of the third side. Therefore, isosceles triangles of the same angles but different sizes can be drawn.

The volume V of a rectangular prism of a particular height varies jointly as the
length I and the width w, and V = 224 ft when I = 8ft and w = 4 ft.
Find I when V = 210 ft' and w = 5ft.
Answer:
6ft
Step-by-step explanation:
Volume of rectangular prism = l x w x h, where h is height. So, we have to work out the height of the first prism in the following way. 224 divided by ( 8 x 4), which gives 7. So, to find l in the second prism, we have to :
L x W x H = 210
L x 5 x 7 = 210
L x 35 = 210
L = 210 divided by 35 = 6

Answer:
like fishing dislike fishing
male 0.62 0.38
female 0.38 0.62
Step-by-step explanation:
To compute column relative frequencies you have to divide the value of each column by the total of each column, as follows:
like fishing dislike fishing
male 35/56 = 0.62 15/39 = 0.38
female 21/56 = 0.38 24/39 = 0.62

Hartley has two 4-section spinners, each labeled 1-4. She will spin both spinners a total of 96 times. For each pair of numbers where the pointers of the spinners land on, Hartley will subtract the smaller number from the greater number.
How many possible total outcomes are there?
How many times should Hartley spin a difference of 1?
How many times should Hartley spin a difference of 0?
Answer:
1) Total outcomes of 1 time = 16
2) 36 times
3) 24 times
Step-by-step explanation:
1) Total outcomesIf both spinners are spinning together, and are labelled from 1 to 4, the the outcome are:
{(1, 1), (1, 2), (1, 3), (1, 4), (2, 1), (2, 2), (2, 3), (2, 4), (3, 1), (3, 2), (3, 3), (3, 4), (4, 1), (4, 2), (4, 3), (4, 4)}
We can count them to find total no. of outcomes
Total outcomes = 16
2) When Difference = 1Following combinations have a difference of 1
{(1, 2), (2, 1), (2, 3), (3, 2), (3, 4), (4, 3)}
n = 6
Probability of getting such combination is: 6/16
How many times Harvey would get such a combination out of 96 times?
[tex]\frac{6}{16}\cdot96=36[/tex]
3) When Difference = 0Following combinations have a difference of 0
{(1, 1), (2, 2), (3, 3), (4, 4)}
n=4
Probability of getting such combination is: 4/16
How many times Harvey would get such a combination out of 96 times?
[tex]\frac{4}{16}\cdot96=24[/tex]
