Answer:
39 sweets
Step-by-step explanation:
the sum of the ratio is
1+4+4= 9
to find the number of sweets shared we say
1/9*X=13 sweets
X=9*13
X=117
therefore Gavin and jim will share equal number of sweets
117-13
104 sweets. Jim gets 52 while Gavin gets 52 sweets.
How many more sweets does Gavin get over Stephen?
52-13
Gavin get 39 more sweets over Stephen. I hope that helps

Find the distance between the two points and simplest rational form (3,-4) (6,-7))
Answer:
[tex]D = 3\sqrt{2}[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (3,-4)[/tex]
[tex](x_2,y_2) = (6,-7)[/tex]
Required
Determine the distance between the two points
Distance (D) is calculated as:
[tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Substitute values for x's and y's
[tex]D = \sqrt{(6 - 3)^2 + (-7 - (-4))^2}[/tex]
[tex]D = \sqrt{(6 - 3)^2 + (-7 +4)^2}[/tex]
[tex]D = \sqrt{(3)^2 + (-3)^2}[/tex]
[tex]D = \sqrt{9+9}[/tex]
[tex]D = \sqrt{18}[/tex]
Express as 9 * 2
[tex]D = \sqrt{9*2}[/tex]
Split:
[tex]D = \sqrt{9}*\sqrt{2}[/tex]
[tex]D = 3*\sqrt{2}[/tex]
[tex]D = 3\sqrt{2}[/tex]
The cost of admission to the Baytown Zoo is $10.50 for each senior citizen, $15.75 for each adult, and $8.25 for each child. What if 2 more tickets for admission are purchased? If the two additional tickets cost $16.50, determine what type of tickets the family purchases. Explain how you can determine the answer without calculating.
Answer:
Child ticket
Step-by-step explanation:
Cost per senior citizen = $10.50
Cost per adult = $15.75
Cost per child = $8.25
Since the cost of the 2 additional ticket is $16.50
Then the only ticket of which two can be purchased with that amount is :
$16.50 / 2
= $8.25
Cost of children ticket.

Solving systems of equations by graphingStep-by-step explanation:
Where the 2 lines intersect is the solution set to the systems of equations.
If the 2 lines are parallel, then they will have no solution.
If the 2 lines are the same, then they will have infinite amount of solutions.
According to the graph, our lines are parallel. Therefore, we have no solution.
The points (10,16) and (30,48) form a proportional relationship. Find the slope of the line through the points. Then use the slope to graph the line.
Answer:
1.6
Step-by-step explanation:
Step one:
given data
x1=10
y1=16
x2=30
y2=48
Required
The slope of the given points
Step two:
The expression for the slope is
S= change in y/change in x
S= y2-y1/x2-x1
S= 48-16/30-10
S=32/20
S=1.6
Hence the slope is 1.6

What is the solution to the equation 1/4x+2=-5/8x-5?
O X=-8
O X=-7
O X=7
O X=8
Answer:
The solution to the equation [tex]\frac{1}{4}x+2=\frac{-5}{8}x-5[/tex] is [tex]\mathbf{x=-8}[/tex]
Option A is correct option.
Step-by-step explanation:
What is the solution to the equation [tex]\frac{1}{4}x+2=\frac{-5}{8}x-5[/tex]
Solving the equation
[tex]\frac{1}{4}x+2=\frac{-5}{8}x-5[/tex]
Subtracting 2 on both sides
[tex]\frac{1}{4}x+2-2=\frac{-5}{8}x-5-2\\\frac{1}{4}x=\frac{-5}{8}x-7[/tex]
Adding 5/8x on both sides
[tex]\frac{1}{4}x+\frac{5}{8}x=\frac{-5}{8}x-7+\frac{5}{8}x\\\frac{2x+5x}{8}=-7 \\\frac{7x}{8}=-7[/tex]
Multiply both sides by 8/7
[tex]\frac{7x}{8}\times \frac{8}{7}=-7 \times \frac{8}{7}\\x=-8[/tex]
So, we get x = -8
The solution to the equation [tex]\frac{1}{4}x+2=\frac{-5}{8}x-5[/tex] is [tex]\mathbf{x=-8}[/tex]
Option A is correct option.

Is the binomial a factor of the polynomial function?
f(x) = x^3 + 3x^2 – 25x – 75
Select Yes or No for each binomial.
Answer:
Yes, the binomial is a factor of the polynomial function.
Step-by-step explanation:
Consider the given polynomial.
Factor out the common term [tex]x^2[/tex] from the first two terms and [tex]-25[/tex] from the last two terms.
[tex]x^3 + 3x^2 -25x-75=x^2(x+3)-25(x+3)[/tex]
Factor out the polynomial.
[tex]x^2(x+3)-25(x+3)=(x+3)(x^2-25)[/tex]
Further, simplify.
[tex](x+3)(x^2-25)=(x+3)(x+5)(x-5)[/tex]
Therefore, [tex]x^3 + 3x^2 -25x-75=(x+3)(x+5)(x-5)[/tex]
A binomial factor is simply a factor with two terms, like (x - a).
Hence, the given polynomial function is binomial as it contains the factor with two terms, like (x - a).

Here is the full question:

[tex]streaked-shelled \ snails \ in \ t he \ sample \ will \ be[/tex]
[tex](a) 50\%. \ (b) 60\%. \ (c) 70\%.[/tex]
Answer:
(a) 0.2007
(b) 0.2510
(c) 0.2150
Step-by-step explanation:
Given that:
The sample size = 10
Sample proportion= 60% 0.6
Let X represents the no of streaked-shell snails.
[tex]X \sim Binom (n =1 0, p = 0.60)[/tex]
The Probability mass function (X) is:
[tex]P(X =x)= (^n_x) p^x(1-p)^{n-x}; x = 0,1,2,3...[/tex]
The Binomial probability with mean μ = np
= 10 * 0.6
= 6
Standard deviation σ = [tex]\sqrt{np(1-p)}[/tex]
= [tex]\sqrt{10*0.6*(1-0.6)}[/tex]
= 1.55
The probability that the percentage of the streaked-shelled snails in the sample will be:
a)
[tex]P(X = 0.5) = ^nC_x p^x (1 -p) ^{(n-x)}[/tex]
[tex]= ^{10}^C_5 * (0.6)^5(1-0.6)^{10-5}[/tex]
[tex]= \dfrac{10!}{5!(10-5)!} * (0.6)^5(1-0.6)^{10-5}[/tex]
= 0.2007
b)
[tex]P(X = 0.6) = ^nC_x p^x (1 -p) ^{(n-x)}[/tex]
[tex]= ^{10}^C_6 * (0.6)^6(1-0.6)^{10-6}[/tex]
[tex]= \dfrac{10!}{6!(10-6)!} * (0.6)^6(1-0.6)^{10-6}[/tex]
= 0.2510
c)
[tex]P(X = 0.7) = ^nC_x p^x (1 -p) ^{(n-x)}[/tex]
[tex]= ^{10}^C_7 * (0.6)^7(1-0.6)^{10-7}[/tex]
[tex]= \dfrac{10!}{7!(10-7)!} * (0.6)^7(1-0.6)^{10-7}[/tex]
