I need to find how much Julia will pay so I have to solve for 3x+5y=50X+5y=31 but if I do that The answer that it gives me I can’t plug it in because is in ( 19/2,43/10) but I need Ane specific answer how can I solve for this ?
Answers
The first step is to find the values of x and y. From the information given,
x is the cost of an adult ticket and y is the cost of a child ticket. The system of equations is shown below
3x + 5y = 50
x + 5y = 31
From the second equation,
x = 31 - 5y
We would substitute x = 31 - 5y into 3x + 5y = 50. We have
3(31 - 5y) + 5y = 50
By expanding the parentheses, we have
93 - 15y + 5y = 50
- 15y + 5y = 50 - 93
- 10y = - 43
Dividing both sides of the equation by - 10,
- 10y/- 10 = - 43/- 10
y = 4.3
Substituting y = 4.3 into x = 31 - 5y, we have
x = 31 - 5 * 4.3 = 31 - 21.5
x = 9.5
If an adult ticket costs $9.5, then the cost of 4 adult tickets is
4 x 9.5 = $38
(1) y - 11 = 4
(2) y = 2x + 3
Answers
Answer:
y = 15 , x = 6
Step-by-step explanation:
you can easily find y from first equation
Move y to the other side of the equation and reverse its sign
so (-11) changes to (+11) and now we have this equation
y = 15
now you must replace 15 instead of y in second equation ,then we have this equation
15 = 2x + 3
now we have to find x
move (+3) to other side of equation and reverse its sign
(+3) changes to (-3)
we have this equation now
15 - 3 = 2x
12 = 2x
x = 12 ÷ 2 = 6

Two litters of a particular rodent species have been born; first with two brownhaired and one gray-haired (litter 1) and the other with three brown-haired and two gray-haired (litter 2). We select a litter at random and then select an offspring at random from the selected litter. (i) What is the probability that the animal chosen is brown-haired
Answers
Answer:
The probability that the animal chosen is brown-haired is 0.6333.
Step-by-step explanation:
Denote the events as follows:
A : a brown-haired rodent
B : Litter 1
The information provided is:
\(P (A|B) =\frac{2}{3}\\\\P(A|B^{c})=\frac{3}{5}\)
The probability of selecting any of the two litters is equal, i.e.
\(P(B)=P(B^{c})=\frac{1}{2}\)
According to the law of total probability:
\(P(X)=P(X|Y_{1})P(Y_{1})+P(X|Y_{2})P(Y_{2})+...+P(X|Y_{n})P(Y_{n})\)
Compute the total probability of event A as follows:
\(P(A)=P(A|B)P(B)+P(A|B^{c})P(B^{c})\)
\(=[\frac{2}{3}\times\frac{1}{2}]+[\frac{3}{5}\times\frac{1}{2}]\\\\=\frac{1}{3}+\frac{3}{10}\\\\=\frac{10+9}{30}\\\\=\frac{19}{30}\\\\=0.6333\)
Thus, the probability that the animal chosen is brown-haired is 0.6333.

Here are two methods to make a 3-digit code.
Codes can have repeated digits.
Method A
For the first digit use an odd number between 0 and 10
For the last two digits use a multiple of 11
Method B
Use three digits in the order odd even odd
Do not use the digit zero
How many more codes can be made with method B than with method A?
In your working you must say how many codes can be made with
each method.
Answers
We can make 55 more codes in Method B than in Method A. In Method A we can make 45 codes and in Method B we can make 100 codes.
Method A:
For the first odd digit, we can have 1,3,5,7,9
For the last two digit we have options 11,22,33,44,55,66,77,88,99
So, for making the code we have 5 options for the first digit and 9 options for the second and the third digit.
Therefore, if we choose 1 as the first digit, we have 9 options for the second and third digits. Similarly for 3,5,7,9
Hence we will have 45 options in Method A
Method B:
For the first digit, we can have 1,3,5,7,9 as options.
For the second digit, we have 2,4,6,8 as an option
For the third digit, we have 1,3,5,7,9 as an option
Therefore, for the first digit, we have 5 options, the second digit 4 options and 5 options for the third digit.
So, we have 5*4*5 options
Hence, we have 100 options available in Method B

The translation of the polygon is 6 units to the left
What is Translation?A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.
A translation in the coordinate plane moves every point on a figure a given distance in a given direction. The position of any point (x, y) on the figure changes to (x + a, y + b), where a and b are real numbers.
Given data ,
Let the polygon be represented as ABCD
Now , the coordinates of the polygon is given as
The coordinate of A = A ( 1 , 3 )
The coordinate of B = B ( 3 , -1 )
The coordinate of C = C ( 7 , -1 )
The coordinate of D = D ( 5 , 3 )
Now , the translated polygon is having the coordinates as
The coordinate of A' = A' ( -5 , 3 )
The coordinate of B' = B' ( -3 , -1 )
The coordinate of C' = C' ( 1 , -1 )
The coordinate of D' = D' ( -1 , 3 )
So , the translation rule is ( x , y ) → ( x - 6 , y )
And , the figure is translated 6 units to the left

3. The t test for two independent samples - Two-tailed example
“Bullying,” according to noted expert Dan Olweus, “poisons the educational environment and affects the learning of every child.” Bullying and victimization are evident as early as preschool, with the problem peaking in middle school. Suppose you are interested in the emotional well-being of not only the victims but also bystanders, bullies, and those who bully but who are also victims (bully-victims). You decide to measure depression in a group of victims and a group of bully-victims using a 26-item, 3-point depression scale. Assume scores on the depression scale are normally distributed and that the variances of the depression scores are the same among victims and bully-victims.
The group of 30 victims scored an average of 21.5 with a sample standard deviation of 10 on the depression scale. The group of 27 bully-victims scored an average of 25.8 with a sample standard deviation of 9 on the same scale. You do not have any presupposed assumptions about whether victims or bully-victims will be more depressed, so you formulate the null and alternative hypotheses as:
H0
: μvictims
– μbully-victims
= 0
H1
: μvictims
– μbully-victims
≠ 0
You conduct an independent-measures t test. Given your null and alternative hypotheses, this is a test. To use the Distributions tool to find the rejection region, you first need to set the degrees of freedom. The degrees of freedom is .
The critical t-scores that form the boundaries of the rejection region for α = 0.01 are ± .
In order to calculate the t statistic, you first need to calculate the standard error under the assumption that the null hypothesis is true. In order to calculate the standard error, you first need to calculate the pooled variance. The pooled variance is s2p
= . The standard error is s(M1 – M2)
= .
The t statistic is .
The t statistic in the rejection region. Therefore, the null hypothesis is . You conclude that victims have a different mean depression score than bully-victims. Thus, it can be said that these two means are different from one another.

Pooled variance is :
\(s^{2}_{p}=\frac{(n_{1}-1)s_{1}^{2}+\left ( n_{2}-1 \right )s_{2}^{2}}{n_{1}+n_{2}-2}=72.8696\)

Answers
The equation -1/8 = -1/8 means that both sides of the equation have the same value, which they do.
The negative sign in front of the fractions means that they are less than zero. The fraction 1/8 means one divided by eight, which is a small quantity.
So, -1/8 means a small negative quantity and -1/8 means the same small negative quantity.

. The length of a rectangle is represented by 4x and the width by 2x + 1 Determine the perimeter of the rectangle as a simplified expression in standard form. (hint: perimeter=2w+21)
Answers
The perimeter of the rectangle can be expressed as 12x+2
What is perimeter of a rectangle?The perimeter of a rectangle is the total distance covered by its boundaries or the sides. Since there are four sides of a rectangle, thus, the perimeter of the rectangle will be the sum of all four sides.
The perimeter of a rectangle is given as 2(l+w)
where l is the length and w is the width.
If the length is represented by 4x and width by 2x+1, therefore the perimeter of the rectangle = 2(4x+2x+1)
= 2( 6x+1)
= 12x+2
the perimeter can also be found by adding all the four sides, this means that
perimeter = 4x+4x+2x+1+2x+1=8x+4x+2= 12x+2
therefore the perimeter of the rectangle is 12x+2.

Rewrite 14 1/3 as an improper fraction
Answers
Answer:
Step-by-step explanation:
((14×3) + 1 )/3 = (43/3)
14 1/3 can be expressed as 43/3, which is an improper fraction.
To rewrite 14 1/3 as an improper fraction, we need to convert the mixed number into a fraction.
First, we multiply the whole number (14) by the denominator of the fraction (3) and add the numerator (1). This gives us the numerator of the improper fraction. The denominator remains the same.
14 × 3 = 42
Next, we add the numerator (1) to the result we obtained above.
42 + 1 = 43
Therefore, the improper fraction equivalent to 14 1/3 is 43/3.
In the fraction 43/3, the numerator (43) represents the total number of parts we have, and the denominator (3) represents the size of each part. It indicates that we have 43 equal parts of size 1/3.
