Answer:
x = 2/15
Step-by-step explanation:
first, create a formula or expression
16x - 7 = x - 5
move x, subtract it
15x - 7 = -5
add 7
15x = 2
divide by 15
x = 2/15

Billy saw 6 tigers and 9 lions at the zoo. What is the ratio of tigers to lions that Billy saw, and what is the
significance of this ratio?
A. 1:3, because the cats Billy saw were in groups of threes
B. 2:3, because Billy saw two-thirds as many tigers as lions
C. 2:3, because two-thirds of the cats Billy saw were tigers
D. 1:3, because Billy saw 3 fewer tigers than lions at the zoo
Answer:
D
Step-by-step explanation:
The correct ratio is 1;3 so that eliminates B and C. The problem doesn't state anything about Billy seeing groups of tigers so D is the only logical answer.

Which pair of angles must be supplementary
1 and 5
5 and 3
4 and 5
4 and 1
The supplementary angle pairs are: angles 4 and 5
What are supplementary angles?Two angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. Which means, if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.
We know that Two Angles are Supplementary when they add up to 180 degrees.
In the given diagram , the pair of angles must be supplementary that are:
angles 1 and 8
angles 2 and 7
angles 4 and 5
angles 3 and 4
angles 1 and 2
angles 7 and 8
angles 3 and 6
angles 5 and 6

Consider a communication source that transmits packets containing digitized speech. After each transmission, the receiver sends a message indicating whether the transmission was successful or unsuccessful. If a transmission is unsuccessful, the packet is resent. Suppose a voice packet can be transmitted a maximum of 8 times. Assuming that the results of successive transmissions are independent of one another and that the probability of any particular transmission being successful is p, determine the probability mass function of the number of times a packet is transmitted.
Answer:
The probability mass function is
[tex]F(x) = [ \left \ 8 } \atop {x}} \right. ] * p^x * q^{n - x }[/tex]
Step-by-step explanation:
From the question we are told that
The maximum transmission time is [tex]n = 8[/tex]
Generally the number of times a packet is transmitted follows a binomial distribution given that the the results of successive transmissions are independent of one another and that the probability of any particular transmission being successful is p
Generally the probability mass function is mathematically represented as
[tex]F(x) = [ \left \ 8 } \atop {x}} \right. ] * p^x * q^{n - x }[/tex]
Here x can take values x = 0 , 1 , 2 , 3 , ... , 7

Lia has a red ribbon that is 2 1/12 long she has a blue ribbon that is 4 times inches long
Answer:
The answer would be 8 1/3!
Step-by-step explanation:
This is because when you multiply you would convert 2 1/12 to an improper fraction of 25/12 and multiply it by 4/1 to get 100/12 which equals 8 with a remainder of 4/12 simplified to 1/3 so your answer is 8 1/3!

Find the equation of a line that contains the points (3,1) and (5,-4). Write the equation in slope-intercept form
Answer:
y= -5x/2+17/2.... (x is between -5/2)
slope intercept= mx+b
y= -5x/2+17/2
Step-by-step explanation:
The equation of line in slope intercept form which passes through the points (3,1) and (5,-4) is [tex]-\frac{5}{2} x+\frac{17}{2}[/tex] .
What is the equation of line in slope intercept form?
The equation of line in the form of [tex]y = mx + b[/tex], is called slope intercept form of a line.
How to find equation of line from two points?The equation of line from two points is given by
[tex]y -y_{1} = \frac{y_{2} -y_{1} }{x_{2}-x_{1} } (x-x_{1} )[/tex]
According to the given question
We have two points (3,1) and (5, -4)
Therefore, the equation of line which passes through the points (3,1) and (5, -4) is given by
[tex](y -1)=\frac{-4-1}{5-3} (x-3)[/tex]
⇒[tex](y-1)=\frac{-5}{2}(x-3)[/tex]
⇒[tex]y -1=\frac{-5}{2}x+\frac{15}{2}[/tex]
⇒[tex]y =-\frac{5}{2} x+\frac{15}{2} +1[/tex]
⇒[tex]y = -\frac{5}{2}x+\frac{17}{2}[/tex]
Hence, the equation of line in slope intercept form which passes through the points (3,1) and (5,-4) is [tex]-\frac{5}{2} x+\frac{17}{2}[/tex] .

Is this correct and why?
Answer:
For a given confidence level, t* is never smaller than z*.
Step-by-step explanation:
t* and z* are the critical value of a confidence interval. For example, at 95% confidence, z* = 1.96. This is because 95% of a normal curve is within ±1.96 standard deviations.
A student's t distribution has the same bell-curve shape as a normal distribution, but is shorter and wider, which is why t* is always larger than z*. As the sample size increases to infinity, the distribution approaches normal.
2x+3y=11, solve for y
Answer:
Let's see what to do buddy...
Step-by-step explanation:
[tex]2x + 3y = 11[/tex]
Subtract the sides of the equation minus 2x :
[tex]3y = 11 - 2x[/tex]
Divided the sides of the equation by 3 :
[tex] \frac{3}{3}y = \frac{ - 2x + 11}{3} \\ \\ y = - \frac{2}{3}x + \frac{11}{3} [/tex]
