Answer:

I will explain how to do this.

Step-by-step explanation: For example A-B is going away from her home because the distance is changing and in the beginning it says Mary starts at her house. So now to continue, where the first letter meets the last letter ( in this scenario its A-B) you'll look at the space between it and count the ticks on the side where it says distance and use the number on the side to guide you. Now for time you'll do the same thing with the ticks on the side. But for where it goes down she is going the opposite way so it'll still be distance but she will be going back home, for the straight line that means she is not moving at all. Hope this helps :)

Answers

Answer:

[tex]\left|\begin{array}{c|c|c|c|c||c}$Country Visited&$UK& $France& $Spain& $Italy &$Total\\&&&&&\\$Number of Customers &968& 248& 2042& 742& 4000\\&&&&&\\$Number of sample&121&31&255&93&500\end{array}\right|[/tex]

Step-by-step explanation:

[tex]\left|\begin{array}{c|c|c|c|c||c}$Country Visited&$UK& $France& $Spain& $Italy &$Total\\$Number of Customers &968& 248& 2042& 742& 4000\\$Number of sample&&&&&&\end{array}\right|[/tex]

Since the company wants to survey 500 customers by the countries visited, the number of samples from each country will be proportional to the number of customers.

For UK, Number of Samples[tex]=\dfrac{968}{4000}X500=121[/tex]

For France, Number of Samples[tex]=\dfrac{248}{4000}X500=31[/tex]

For Spain, Number of Samples[tex]=\dfrac{2042}{4000}X500\approx 255[/tex]

For Italy, Number of Samples[tex]=\dfrac{742}{4000}X500\approx 93[/tex]

The completed table therefore is:

what is the length of a 45 arc

Answers

Answer:

1.5707

Step-by-step explanation:

i solved it using the furmola :

[tex]2\pi \times r \frac{45}{360} [/tex]

Answer:

a = 1.57 in

Step-by-step explanation:

We know that the length of the arc in a circle is proportional to its corresponding angle which means:

a corresponds to 45

2πr corresponds to 360

then

[tex]\frac{a}{45} = \frac{2\pi r}{360}[/tex]

then

a = (45÷360)×4×π

After reaching the summit, she descends 14 feet in 213 minutes. If she continues at this rate, where will Maggie be in relation to the summit after 8 minutes?

Answers

Complete Question

Maggie is rock climbing. After reaching the summit, she descends 14 feet in 213 minutes. If she continues at this rate, where will Maggie be in relation to the summit after 8 minutes?

Answer:

Maggie will be  [tex]x = 0.53 \ feet[/tex]  from the previous position

Step-by-step explanation:

From the question we are told that

   The distance of descent is  [tex]d = 14 ft[/tex]

    The time  taken is  [tex]t = 213 \ minutes[/tex]

So she descended 14ft  in  213 minutes

 So she would  descend x ft in 8 minutes

   Hence

              [tex]x = \frac{14 * 8 }{213}[/tex]

             [tex]x = 0.53 \ feet[/tex]

What is \text{P(not }3)P(not 3)start text, P, left parenthesis, n, o, t, space, end text, 3, right parenthesis? If necessary, round your answer to 222 decimal places.

Answers

Answer:

There is no enough information to determine probability of not having 3, P(not 3).

Suppose we were given the probability of having 3, P(3), we can easily find P(not 3).

The probability of success plus the probability of failure of an event is always equal to 1.

If p is the probation success, and q, of failure, then p + q = 1

So,

P(3) + P(not 3) = 1

That is

P(not 3) = 1 - P(3).

Find the area of the triangle

Answers

Answer:

14

Step-by-step explanation:

Base:4 + 3=7

hight:3

area of Triangle: b*h/2

therfore the answer is 14m squared

The triangle with a base of 4 and a height of 3 has an area of 6 square meters.

Based on the given information, we have a triangle with a base of 4 and a height of 3.

To calculate the area of the triangle, we use the formula:
Area = (base * height) / 2.

Substituting the values, we have
Area = (4 * 3) / 2    

        = 12 / 2
        = 6

Therefore, the area of the triangle is 6 square meters.

Answer: No

Step-by-step explanation: To find out if this ordered pair is a solution to the following inequality, simply plug the values in for x and y.

So we have -3 < -5(3) + 3(-3) or -3 < -15 + -9 or -3 < -24.

What is the area of a trapezoid with a height of 10 and B1 of 9 and B2 of 4

Answers

Answer: 65

Step-by-step explanation: In this problem, we're given that the height of a trapezoid is 10 and the bases has lengths of 9 and 24 and we're asked to find the area of the trapezoid. Since we're given the lengths of the bases, let's use our formula for the area of a trapezoid which involves the bases.

Area of a trapezoid is shown at the bottom your screen.

Now plug the information into the formula.

Simplify inside parentheses first.

Then multiply 1/2 by 10 to get 5.

Then you have (5)(13) which is 65.

So the area of the trapezoid is 65.

-Combine like terms:

[tex]6x - 7 + 20x + 5 = 180\textdegree[/tex]

[tex]26x - 2 = 180\textdegree[/tex]

Add both sides by 2:

[tex]26x - 2 + 2 = 180\textdegree + 2[/tex]

[tex]26x = 182\textdegree[/tex]

Identify the center and radius of each. Photo attached.

Answers

Answer:

Center ~ ( -4, 3 ), Radius ~ 2; Option A

Step-by-step explanation:

~ We know that the standard circle equation ( x - a )^2 + ( y - b )^2 = r^2  provided r ⇒ radius of the circle, centered at ( a, b ) ~

1. If we are given the circle formula ( x + 4 )^2 + ( y - 3 )^2 = 4, it would be that the center points ( a, b ) would be the inverse of 4 and -3, provided the formula is -a and -b: center ( -4, 3 )

2. Now the radius in the formula ( x - a )^2 + ( y - b )^2 = r^2, is noted by r such that in ( x + 4 )^2 + ( y - 3 )^2 = 4, r^2 is 4 ⇒ r = √4 = 2

3. We now know that the center of this circle is ( -4, 3 ) with a radius of 2, and the only graph that represents that function is the first graph ~

Answer: Center ~ ( -4, 3 ), Radius ~ 2

A student wants to save at least $5000 for college. She begins with a savings account set up by her parents containing $2,500. Each month she deposits an additional $50 into the account. Fill in the first blank with the correct expressions that make the statement true.
(Attached is the statement and the choices)

Answers

Answer: She deposits 50 dollars per month right? But as known her parents deposited her 2,500. So, it will take her 50 months to complete the amount of  5000 dollars needed for college.

Step-by-step explanation: Im not good with equations but here  we go.

First: AS we know the account already had 2,500, and every month she deposits 50$.

What we can do is to divide 2,500 divided by 50 which will be 50.

y = -9x - 14
x-intercept
y-intercept:​

Answers

Answer: The x intercept is (-14/9,0)  which means the x intercept is -14/9. The y intercept is -14.

Step-by-step explanation:

the x intercept is when y is 0  so using the equation we could solve for x by putting in 0 for y.

0=--9x - 14

+ 14        +14

14= -9x  

x= -14/9

The y intercept is when x is zero so using the same method we will put in 0 for x in the equation and solve for y.

y= -9(0) - 14

y= 0-14

y= -14

The students are doing a fundraiser to help out a friend. They are selling chocolate and cookies for $3 and $2.50 respectively. The cookies were presold to 60 people. At least how many of the chocolates must be sold to collect $255?

Answers

Answer:

At least 18 chocolates sold to collect $225

Step-by-step explanation:

~ Let's say x ⇒ the number of chocolates, y ⇒ the number of cookies ~

1. We can see that the number of chocolates/ cookies * the cost of chocolates/cookies = the total cost of chocolates/cookies. Provided this, it would be that 3x and 2.5y would represent the cost of chocolates and cookies.

2. It is given that there was $225 sold from chocolates and cookies, so we can say that 3x + 2.5y = 225 from this assumption.

3. That being said it is also known that the cookies were sold to 60 people, so we can assume that 60 cookies were sold out, 1 were person. With this information we can see that 3x ⇒ 3 * 60 = 180 ⇒ cost of cookies sold

4. Now we can substitute this value of 3x into the equation 3x + 2.5y = 225, as such: 3x + 2.5y = 225 ⇒ 180 + 2.5y = 225, and now we can solve for y ~

180 + 2.5y = 225,

2.5y = 225 - 180,

2.5y = 45,

y = 45/2.5,

y = At least 18 chocolates sold to collect $225
