Answer:

The scooter travels 15 feet in 1 second

The scooter travels 45 feet in 3 seconds

The scooter travels 60 feet in 4 seconds

The scooter travels 75 feet in 5 seconds

Step-by-step explanation:

First, let's find the number of feet the scooter travels in 1 second

(30 : 2) ÷ 2 = 15 : 1

Now that we have the unit rate, we can easily find the answers to the other questions.

(15 : 1) x 3 = 45 : 3

(15 : 1) x 4 = 60 : 4

(15 : 1) x 5 = 75 : 5

Step-by-step explanation:

Inequality shows a relationship between two numbers or two expressions.

The inequality that could be used to determine the mean number of miles, m, he would need to run each day for 4 more days to achieve his goal is

15 + 4m ≥ 35

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥  

We have,

His goal for this week is to run a minimum of 35 miles.

So far this week, he has already run 15 miles.

The inequality that could be used to determine the mean number of miles, m, he would need to run each day for 4 more days to achieve his goal.

15 + 4m ≥ 35

4m = number of m miles run in 4 days.

Thus,

The inequality that could be used to determine the mean number of miles, m, he would need to run each day for 4 more days to achieve his goal is

15 + 4m ≥ 35

Answer:

Only option D is one of the transformations needed.

Step-by-step explanation:

The graph of f(x)=x^2 is a positive parabola with x=0 as the zero in ordinates and also 0 as a zero x. This is, the graph passes in (0,0) and this is the only point it crosses both axis, then for every x value we will gave a positive f(x).

Here I attach a graph that shows both, f(x)=x^2 and g(x)=-x^2+16x-44.

As you can see, for transforming f(x) in g(x) we need to reflect it over the x axis, as g is open downwards. Then, as the quadratic term is still being x^2 we do not wide it (as you see in the graph both curves are equally widened).

Then, we can also see that the graph is shifted right, so we do not shift it left 8 units (notice that we shift it right 8 units).

So, after reflecting over the x axis and shifting right we need to shift it UP, as we can see the graph is over the x axis.

So, the three transformations needed are:

1. reflect over the x axis

2. shift right 8 units

3. shift up 20 units.

So, from the options you proposed we chose only d, to which we MUST add the transformations noted above.

Sorry for the mistake!

Step-by-step explanation:

289.76-54.88-54.88=180/2=90

Perimeter is the sum of the length of the sides used to make the given figure. The length of the field is 90 meters.

Perimeter is the sum of the length of the sides used to make the given figure.

Given that the width of the field is 54.88 meters and the perimeter of the field is 289.76 meters. Therefore, we can write the perimeter as,

Perimeter = 2(Length + Width)

289.76 meters = 2(Length + 54.88 meters)

289.76meters / 2 = Length + 54.88 meters

144.88metes = Length + 54.88 meters

Length = 144.88 meters - 54.88 meters

Length = 90 meters

Hence, the length of the field is 90 meters.

Answer:

We use students' t distribution therefore degrees of freedom is v= n-2

Step-by-step explanation:

Confidence Interval Estimate of Population Regression Co efficient β.

To construct the confidence interval for β, the population regression co efficient , we use b, the sample estimate of β. The sampling distribution of b is normally distributed with mean β and a standard deviation σ.y.x / √(x-x`)². That is the variable z = b - β/σ.y.x / √(x-x`)² is a standard normal variable. But σ.y.x  is not known so we use S.y.x and also student's t distribution rather than normal distribution.

t= b - β/S.y.x / √(x-x`)² = b - β/Sb    [Sb = S.y.x / √(x-x`)²]

with v= n-2 degrees of freedom.

Consequently

P [ - t α/2<  b - β/Sb  < t α/2] = 1- α

or

P [ b- t α/2 Sb<   β  < b+ t α/2 Sb] = 1- α

Hence a 100( 1-α) percent confidence for β the population regression coefficient for a particular sample size n <30  is given by

b± t α/2 Sb

Using the same statistic a confidence interval for α can be constructed in the same way for  β  replacing  a with b and Sa with Sb.

a± t α/2 Sa

Using the t statistic  we may construct the confidence interval for U.y.x for the given value X0 in the same manner

Y~0 ± t α/2(n-2) SY~

Y~0= a+b X0

Answer: yes

explanation: it starts at the origin of 0,0, which means its a proportional relationship

The correct graphs which represents a function is shown in ''Option B.''

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

There are four graphs are shown in image.

Now, We can check all the graph by vertical line test.

If the vertical line cut only at one point of the graph, then, it shows the function.

If the vertical line cut more than one point of the graph, then, it cannot shows the function.

Hence, By vertical line test,

The correct graphs which represents a function is shown in Option B.

What is Multiplication?

Along with addition, subtraction, and division, multiplication is one of the four basic arithmetic operations. In mathematics, multiplication is the repeated addition of groups of equal size.

Here given, Brianna makes a model of the Eiffel Tower for a school project.

It is also given that the model is 25 cm wide at the bottom and Brianna used a scale of 1 centimeter for every 5 meters.

By multiplication, we can find the actual length of Eiffel tower

Here 1 centimeter for every 5 meters.

So, 25 centimeter means (5×25) = 125 meters.

Therefore, the actual length of the Eiffel tower is 125 meters.

Answer:

Yes, this is a function.

No, this is not a linear function.

Step-by-step explanation:

A function is a process or a relation that associates each element x of a set X, the domain of the function, to a single element y of another set Y

Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable.
