Answer:

[tex]d =\frac{10}{3}t + 11[/tex]

Step-by-step explanation:

Given

Represent time with t and distance with d

The time at which he sets his timer is 0.

So:

[tex](t_1,d_1) = (0,11)[/tex]

After 3 seconds:

[tex](d_2,d_2) = (3,21)[/tex]

Required

Determine the linear equation

First, we need to determine the slope (m):

[tex]m = \frac{d_2 - d_1}{t_2 - t_1}[/tex]

Substitute in, values

[tex]m = \frac{21 - 11}{3 - 0}[/tex]

[tex]m = \frac{10}{3}[/tex]

Next, we determine the equation sing

[tex]d - d_1 = m(t - t_1)[/tex]

Where

[tex](t_1,d_1) = (0,11)[/tex]

[tex]m = \frac{10}{3}[/tex]

[tex]d - 11 =\frac{10}{3}(t - 0)[/tex]

[tex]d - 11 =\frac{10}{3}t - 0[/tex]

[tex]d - 11 =\frac{10}{3}t[/tex]

Add 11 to both sides

[tex]d - 11+11 =\frac{10}{3}t + 11[/tex]

[tex]d =\frac{10}{3}t + 11[/tex]

Hence, the linear equation is: [tex]d =\frac{10}{3}t + 11[/tex]

The linear equation used to represent Carlos distance (d) from his starting position after t seconds is d = 3t + 12

A linear equation is given by:

y = mx + b;

where y, x are variables, m is the rate of change and b is the y intercept.

Let d represent Carlos distance from his starting position after t seconds.

Given that He starts a timer when he is  12 feet from his starting position, hence b = 12 feet. After 3 seconds, Carlos is 21 feet from his starting position. Therefore:

21 = 3m + 12

3m = 9

m = 3 ft per second

The linear equation used to represent Carlos distance (d) from his starting position after t seconds is d = 3t + 12

Answer: f(x) = -3/2x -2

Step-by-step explanation:

Slope form of a line is y=mx+b, where b is the y-intercept and m is the slope. We find the y-intercept when we look at when x is 0 which would be -2. The slope is graphing to plots and determining if the slope is positive- going up- or negative- going down. The slope is going down and after using y2 - y1 / x2 - x1, I found the slope was -3/2.

Answer: 325

Explanation:

Let the number of adult tickets be x

( since there are an unknown amount of tickets for adults, we already know how many student tickets there are)

Let the number of student tickets be x+60

710=x+x+60

710=2x+60

 -60        -60

650=2x

650/2

= 325

Adult tickets=325

Student tickets=385

Answer:

A coefficient is the number that the variable is multiplied by.

The variable is the unknown value, often represented by a letter or symbol.

The constant is the number that is not affected by a variable value, hence the term "constant."

Using the logic above, we can conclude that 4 is the coefficient, x is the variable, and -12 is the constant.

Answer:

16, 8, 28, 84, 10, 16, and 96

Step-by-step explanation:

Bc its a parallelogram, the opposite sides are equal. so HI is equal to KJ which is 16. For GH its parallel to GJ so its 8. For the measure of KIH, we know that the measure of IKJ is 28, so the opposite side, it would be 28 for KIH. For the measure angle of KJI, the same applies, the opposite is KHI which is 84. KH is the opposite of JI which is 10. For HJ, you have half the line which we know from GJ is 8, so the other half would also be 8 making HJ 16 in total. For the measure angle of JIH, the opposite is JKH, we know that 28 makes up a small part of that. The angle KHI also distributes into this, 28+84=112. Each triangles angles should equal up to 180 so 180-112= 68 so the other side of 28 is 68. Now the 84 angle isn't completely distributed into the angle but we needed that to figure out the 68 part. So now that we have 28 and 68 we add that together and get 96.

Answer:

the options are not numbered so I have added each of the correct answers under their corresponding question number. the answers in bold letters are right options from the question.

Step-by-step explanation:

a.)

the width of the interval decreases, since the standard error decreases. this is the answer to this question. this happens to a confidence interval as the sample size gets increased. that is if every other thing remains the same.

b.

the answer to this question is that the interval gets wider since the t value required to Capture a larger proportion of the sampling distribution of the sample mean gets larger. so the last option is the answer to the question.

c.

the margin of error shows the degree of random sampling error that is in the result of a survey. the correct answer to this question is this:

in a confidence interval for a population mean, the margin of error describes the difference between the sample mean and the population mean. Due to the random sampling method, different sample means will be different.

d.

regarding this question, we use a z score because:

For large random samples the sampling distribution of the sample proportion is approximately normal.

e.

the answer to this is false.

thank you!
