In order to determine the average price of hotel rooms in Atlanta, a sample of 63 hotels were selected. It was determined that the test statistic (z) was $-1.53. We would like to test whether or not the average room price is significantly different from $110. Population standard deviation is known to us. Compute the p-value.

Answer:

904.8cm

Step-by-step explanation:

The volume of a sphere is given as

[tex] \frac{4}{3}\pi {r}^{2} [/tex]

There is only one variable, the radius, which we are given in the problem.

since the radius is 6 cm, we can plug that in to the formula

[tex] \frac{4}{3} \pi {6}^{2} [/tex]

Put this into the calculator, and we see that the volume is 904.8cm rounded to the nearest tenth.

Answer:

36.5

Step-by-step explanation:

y= -x²+73x-520

which can be represented as ax²+bx+c

a= -1, b= 73, c = -520

for maximum value of y,

the formula is

c - (b² / 4a)

= -520 - (73² / 4×(-1))

= -520 - (5329 / -4)

= -520 + 1332.25

= 812.25

Solving for x,

812.25 = -x²+73x-520

or, x²-73x+ 1332.25 = 0

Solving,

x= 36.5

Answer:

6x and 1x or x

Step-by-step explanation:

the highest common factor of 6x and 66xy in 6x

6x ÷ 6x = 1

66xy ÷ 6x = 11y

the lowest common factor of 6x and 66xy is 1x or x

6x÷ 1x =6

66xy÷ 1x = 66y

6x÷ x = 6

66xy ÷ x = 66y

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

mpho is the 50th fastest and slowest runner in her school.

Now,

Since, mpho is the 50th fastest and slowest runner in her school.

Hence, Total number of students = (50 + 50) - 1

                                                   = 100 - 1

                                                   = 99

Thus, There are 99 students in her school.

Answer:

slope= rise over run means divide rise by run

Answer:

when there is a linear equation and line. first, find where you see a point that has whole numbers. graph them or circle them. Next, go to point to pint using the lines. do not use the slanted line. go up (rise) and count how many boxes you passed (be careful it could go by 2's) and then go across to the other point (run). count how many boxes you passed. now you put the up number or rise number over the run number. Rise/run. you'll get a fraction, simplified it if needed.

or do slope form which is just find 2 points that have whole numbers. Label the first one (x1,y1) and the second one (x2,y2) the you do (Y2 - Y1) over (X2 - X1). you'll get a fraction and you'll simplified it if needed

formula for area of triangle is A = height (straight line from the base to the tip, not the length of one of the sides) x length of base / 2 ( A= hb/2)

Answer:

A =  2 outcomes B = 4 outcomes C = 7 outcomes

Step-by-step explanation:

A has two outcomes because when you flip a coin you can only land on heads or tails

B has four outcomes becuase when picking a random season there are only four possible seasons to be picked.

C has seven outcomes becuase when picking a random day of the week there are only 7 possible days that can be picked,

Answer: The probability of the pointer lands on red(R) both spin =

Step-by-step: The number of parts = 6

The pointer is spun twice.

To find the probability of the pointer lands on red(R) both spin.

Formula

Probability of an event = number of required outcomes ÷ the total number of outcomes.

P(A and B) = P(A)×P(B)

Now,

For one spin,

A = RED comes.

For second spin,

B = RED comes

So,

P(A) = and P(B) =

Then,

P(A and B) = × =

Hence, the probability of the pointer lands on red(R) both spin =

Answer:

$16

Step-by-step explanation:

Given data

The cost price of the shoe= $20

Discount = 20%

Let us find the amount of the 20% discount

=20/100*20

=0.2*20

=$4

Hence the selling price will be

=20-4

=$16

Step-by-step explanation:

9 + y^2 = 49

y^2 = 40

y = √40 = 2√10

4.5/3 = 2√10/5x

22.5x = (3) 2√10

22.5x = 6√10

x = 6√10/22.5 = 3√10/11.5

The tangent line and radius or diameter of the circle intersect at a right angle and the tangent intersects the circle at a single point only. Then the correct option is A, B, and D.

It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

The tangent line and radius or diameter of the circle intersect at a right angle.

And the tangent line intersects the circle at a single point only.

The number of the tangent line depends on the point from which the tangent is drawn.

Answer:

Well there if you look at the choices given its only 4.71 and 8.52. According to the model is looks like we need to find the hypotnuse which is the longest lightning of any triangle. But here’s the thing, in every triangle if you add the two legs, the sum of that number has to be GREATER then the hypotnuse or it wouldn’t stick. If your dd 2+3 together you get 5. Only the last option is greater then 5. The final answer is 8.52.

Remeber, you CAN’T use the Pythagorean theroum on any triangle with out a 90 degree angle. Pythagorean Theorem only works for right triangles. This is why the first option is given to trick you.

Answer:

For some sets of data, some of the largest value, smallest value

, first quartile, median, and third quartile may be the same. For instance, you might have a data set in which the median and the third quartile are the same. In this case, the diagram would not have a dotted line inside the box displaying the median. The right side of the box would display both the third quartile and the median. For example, if the smallest value and the first quartile were both one, the median and the third quartile were both five, and the largest value was seven, the box plot would look like:

In this case, at least

25

25

% of the values are equal to one. Twenty-five percent of the values are between one and five, inclusive. At least

25

25

% of the values are equal to five. The top

25

25

% of the values fall between five and seven, inclusive.

Answer:

First, create a scale that includes all the numbers- that being, you can plot both the minimum and maximum values on it.

Next, draw a line of a set height (I tend to use 2 squares in my work) where the median is. Next, draw similar lines, at the same height, for the rest of the values- both quartiles and the maximum values. You can obviously do this in whatever order you like, but that's how I do it.

Next, join up the tops and bottoms of the quartiles, with the median in the middle, and connect the middles of the quartiles to their corresponding minimum or maximum values.

Voila, my friend. You have a box plot.
