Answer:
The dependent variable is distance, the equation is y = 33x, and the dragonfly will travel 792 miles
Step-by-step explanation:
ordered pairs: (0, 0) (2, 66) (4, 132) (6, 198)
slope of linear equation = change in y ÷ change in x
⇒ slope = (132 - 66) ÷ (4 - 2) = 33
Therefore, equation of the line: y = 33x
When x = 24, y = 33 × 24 = 792 miles
Distance is dependent on time, therefore distance is the dependent variable and time is the independent variable.

A bag contains 2 red marbles, 6 blue marbles and 7 green marbles. If two marbles are drawn out of the bag, what is the probability, to the nearest 100oth, that both marbles drawn will be red?
Answer:
0.01 (nearest hundredth)
Step-by-step explanation:
[tex]\mathsf{probability=\dfrac{number \ of \ favorable \ outcomes}{number \ of \ total \ outcomes}}[/tex]
Total number of marbles (total outcomes) = 2 + 6 + 7 = 15
⇒ Probability of the first marble being red = [tex]\dfrac{2}{15}[/tex]
As there is no replacement, the total number marbles is now 15 and there is only 1 red marble left.
⇒ Probability of the second marble being red = [tex]\dfrac{1}{14}[/tex]
So the probability of the 1st and 2nd marble being red is:
[tex]\dfrac{2}{15}\times \dfrac{1}{14} = \dfrac{1}{105}[/tex] = 0.01 (nearest hundredth)

What is the slope and y-intercept of this line?
y=−12x+7
Answer:
-12
Step-by-step explanation:
y = mx + b
the one being multiplied to x is the slope
Answer:
slope: -12
y-intercept: 7
Step-by-step explanation:
The slope-intercept form of the equation of a line is
y = mx + b
where m = slope, and b = y-intercept.
Your equation is
y = -12x + 7
Your equation is already in the slope-intercept form.
m = -12
b = 7
slope: -12
y-intercept: 7

You and your friends order a meal for $116.29. How much tip should you leave if you want to leave a 12% tip?
Answer:
$13.95
Step-by-step explanation:
$166.29 ×12/100
=$13.95 will be the tip.
Answer:
$13.95
Step-by-step explanation:
Convert the 12% to an actual number that can be used in a calculator. For percents, this is done by dividing the percent (in this case 12%) by 100%.So, the conversational term "12%" becomes 12% / 100% = 0.12 in terms of a real mathematical number. Then you need to find out what 12% of your $116.29 meal cost is.This is always done by multiplying 0.12 by $116.29, or 0.12 x $116.29=$13.95.
Damita says the equations 0.8x - 0.8 = 1.6 and 4/5 ( x - 1 ) = 1 (3/5) are the same. How can she show this without solving the equations?
To show that the equations are the same, we need to rewrite one of the equations as an equivalent equation of the second
Damita's claim is true
How to show the equations are the sameThe equations are given as:
0.8x - 0.8 = 1.6
4/5 ( x - 1 ) = 1 (3/5)
We need to rewrite one of the equations, as follows:
4/5 ( x - 1 ) = 1 (3/5)
Express as decimal
0.8 ( x - 1 ) = 1 + 0.6
Open the brackets
0.8x - 0.8 = 1.6
Now we have:
0.8x - 0.8 = 1.6 (the first equation) and 0.8x - 0.8 = 1.6 (the equivalent of the second equation)
The above shows that both equations are the same

Step-by-step explanation:
Describe two different ways that you could find the product 3x990
990 = 1000 - 10
so 3 x 990 = 3 x (1000 - 10) = 3 x 1000 + 3 x (-10) = 3000 - 30 = 2970
and
990 = 900 + 90
so 3 x 990 = 3 x (900 + 90) = 3 x 900 + 3 x 90 = 2700 + 270 = 2970

y-6=6(x-1)y-6=6x-6y=6xAn analyst wants to determine if there is any difference in the amount of time teenagers play video games between two years. To do this, he takes a random sample of teenagers and gathers the average time they spent playing video games the previous year and compares it to the average time they spent playing video games this year. Suppose that data were collected for a random sample of 15 teenagers, where each difference is calculated by subtracting the time spent playing video games this year from the time spent playing video games last year. Assume that the times are normally distributed. What is/are the critical value(s) of the t-test statistic for this hypothesis test, where α=0.10? Use a comma and a space to separate answers as needed.
Answer:
The critical value is [tex]t_{\frac{0.10}{2} , 14 } =[ - 1.761,1.761][/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 15
The level of significance is [tex]\alpha = 0.10[/tex]
The null hypothesis is [tex]H_o : \mu _1 = \mu_2[/tex]
The alternative hypothesis is [tex]H_a : \mu_1 \ne \mu_2[/tex]
Here [tex]\mu_1[/tex] is average time for previous year
[tex]\mu_2[/tex] is the average time for current year
Generally the degree of freedom is mathematically represented as
[tex]df = n -1[/tex]
=> [tex]df = 15 - 1[/tex]
=> [tex]df = 14[/tex]
Generally from the student t distribution table the critical value for [tex]\frac{\alpha }{2}[/tex] at a degree of freedom of [tex]df = 14[/tex] for a two tailed test is
[tex]t_{\frac{0.10}{2} , 14 } =[ - 1.761,1.761][/tex]

Consider the sequence 10, 2..
Create a totally different sequence that begins 10,2, ... For your sequence, write the next four terms and an equation for t(n). Cannot be arithmetic or geometric.
Answer: see below
Step-by-step explanation:
1) 10, 2, 1.2, 1.12, 1.112, 1.1112
[tex]t_n=\dfrac{t_{n-1}}{10}+1[/tex]
t₁ = 10
t₂ = 10/10 + 1 = 2
t₃ = 2/10 + 1 = 1.2
t₄ = 1.2/10 + 1 = 1.12
t₅ = 1.12/10 + 1 = 1.112
t₆ = 1.112/10 + 1 = 1.1112
2) 10, 2, -2, -4, -5, -5.5, ...
[tex]t_n=\dfrac{t_{n-1}}{2}-3[/tex]
t₁ = 10
t₂ = 10/2 - 3 = 2
t₃ = 2/2 - 3 = -2
t₄ = -2/2 - 3 = -4
t₅ = -4/2 - 3 = -5
t₆ = -5/2 - 3 = -5.5
