Each year, a radio station awards a prize vacation to one of its listeners. The prize winner has the option of choosing a vacation to Hawaii, New York, California, or Alaska. In the past, 35% of winners chose Hawaii, 25% chose New York, 25% chose California, and the remaining winners chose Alaska. If the radio station uses 40 chips in four different colors to model this situation, how many colored chips should they use to represent each vacation option
The colored chips they used to represent each vacation option are:
Hawaii: 14 blue chips
New York: 10 yellow chips
California: 10 red chips
Alaska: 6 green chips
How many colored chips should they use to represent each vacation option?The radio station awarded 40 different colored chips to 100% winners.
To know how many colored chips should they use to represent each vacation option the following steps are taken:
Hawaii = ( 35/100) × 40
= 14 blue chips
New York = (25/100) ×40
= 10 yellow chips
California = (25/100) ×40
= 10 red chips
Alaska = (15/100) × 40
= 6 green chips

A line that includes the point (0, –16) has a slope of–17/2. What is its equation in slope - intercept form?
The equation in slope-intercept form with slope --17/2 passing through the point (0, -16) is 2y = -17x -32
What is slope?The slope of a line is the ratio of the amount that y increases as x increases some amount. Slope tells you how steep a line is, or how much y increases as x increases. The slope is constant (the same) anywhere on the line.
Equation of straight line in slope-intercept form is y = mx + c
y = -16, x = 0, m(slope) = -17/2 c = y-intercept
-16 = 0(-17/2) + c
c = -16
Equation of line becomes
y = -17x/2 -16

What is the probability of tossing a coin three times and getting heads
each time? *
Answer:
probability of tossing a coin 3 times and getting heads each time is 1/8
Step-by-step explanation:
A coin has 2 sides (heads and tails) therefore you have a 50% chance of getting either heads or tails for each toss. Therefore, the probability of getting heads for 1 toss is 1/2. Now, tossing it 3 times and getting heads each time essentially means you would have to do (1/2)×(1/2)×(1/2) which would give you 1/8 as the probability of tossing a coin 3 times and getting heads each time.

what is a congruent polygon
A congruent polygon refers to two or more polygons that have the same shape and size. There must be an equal number of sides between two polygons for them to be congruent.
Congruent polygons have parallel sides of equal length and parallel angles of similar magnitude. When two polygons are congruent, they can be superimposed on one another using translations, rotations, and reflections without affecting their appearance or dimensions. Concluding about the matching sides, shapes, angles, and other geometric properties of congruent polygons allows us to draw conclusions about them.

A container in the shape of a cylinder is 15. 5cm high and has a diameter of 12. 8cm. How many millilitres of chocolate milk will the container hold if it is filled to the top? About how many litres would that be?
The container will hold 5,998.144 milliliters of chocolate milk. It will hold approximately 5.998 liters of chocolate milk.
Given that the container is in the shape of a cylinder and has a height of 15.5 cm and a diameter of 12.8 cm. So the radius of the container is r= 1/2 of the diameter=12.8/2=6.4 cm. The formula for the volume of a cylinder is given by;
`V = πr²h`
where `π` is a constant value approximately equal to 3.14, `r` is the radius of the cylinder, and `h` is the height of the cylinder.
In this problem, `r=6.4 cm` and `h=15.5 cm`. Thus, the volume of the cylinder can be calculated as;`V = πr²h``V = 3.14 × 6.4² × 15.5``V = 5,998.144 cm³`
Therefore, the container can hold 5,998.144 cubic cm of chocolate milk. We can convert this volume to milliliters by multiplying by 1,000.1 cm³ = 1 ml`5,998.144 cm³ = 5,998.144 × 1 ml/ 1cm³ = 5,998.144 ml`
So, the container will hold 5,998.144 ml of chocolate milk. To find the volume in liters, we can divide the volume in milliliters by 1,000.1 L = 1,000 ml`5,998.144 ml = 5,998.144 / 1,000 L = 5.998144 L`
Therefore, the container will hold approximately 5.998 liters of chocolate milk (rounded to three decimal places).

Given the pre-image ABCD and the image after a dilation, A'B'C'D', what is true about the polygons? Check all that apply.
The length AB is 2.
The length A'B' is 3.
The image is smaller than the pre-image.
The scale factor is Three-halves.
The scale factor is Two-thirds.
For the given dilation of the polygons the correct answer are The length AB is 2. The length A'B' is 3. The scale factor is Three-halves.
What is dilation?Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is a picture with the same shape as the original. Yet, there is a variation in the shape's size. The initial form should be stretched or contracted during a dilatation. The phrase "scale factor" describes this transition.
The distance formula for the coordinates is given as:
d(A, B) = |x1 - x2|
From the figure we observe that,
d(A, B) = |2 - 4|
d(A, B) = |-2|
d(A, B) = 2 units.
Hence, option A is correct.
Also, the length of A'B' is:
d(A', B') = |3 - 6| = |-3| = 3 units.
Hence, option B is correct.
The original shape is called the pre-image in a transformation (in this example, a dilation), and the transformed shape is called the image.
The third response is untrue since the picture is larger than the pre-image.
The scale factor of the images is:
2k = 3
k = 3/2.
Hence, option 4 is correct.
The last option is also false, as the scale factor is already determined.
Hence, for the given dilation of the polygons the correct answer are The length AB is 2. The length A'B' is 3. The scale factor is Three-halves.

On the planet of Mercury, 4 -year-olds average 2.8 hours a day unsupervised. Most of the unsupervised children live in rural areas, considered safe. Suppose that the standard deviation is 1.5 hours and the amount of time spent alone is normally distributed. We randomly survey one Mercurian 4-year-old living in a rural area. We are interested in the amount of time X the child spends alone per day. (Source: San Jose Mercury News) Round all answers to 4 decimal places where possible. a. What is the distribution of X?X∼N ( b. Find the probability that the child spends less than 1.1 hours per day unsupervised. c. What percent of the children spend over 4.6 hours per day unsupervised. \% (Round to 2 decimal places) d. 64% of all children spend at least how many hours per day unsupervised? hours.
64% of all children spend at least 3.376 hours per day unsupervised.
a. The distribution of X is X~N(2.8,1.5^2) with a mean of 2.8 hours and a standard deviation of 1.5 hours.
b. Let Z = (X - μ)/σ be the standard normal variable associated with X.
The probability that the child spends less than 1.1 hours per day unsupervised is P(X < 1.1)= P(Z < (1.1 - 2.8)/1.5) = P(Z < -1.1333) = 0.1285 (rounded to four decimal places).
c. We want to find the percentage of children who spend over 4.6 hours per day unsupervised.
Therefore, we need to find P(X > 4.6).
We can find this using the standard normal variable Z by the formula,
P(X > 4.6) = P(Z > (4.6 - 2.8)/1.5)
= P(Z > 1.2)
= 0.1151.
Therefore, the percentage of children who spend over 4.6 hours per day unsupervised is 11.51%.
d. To find the number of hours spent alone by 64% of all children,
we need to find the z-score associated with the 64th percentile.
We can find this using a table of standard normal probabilities.
The z-score associated with the 64th percentile is approximately 0.3853.
Therefore, we have (X - μ)/σ = 0.3853.
Solving for X, we have
X = 0.3853(1.5) + 2.8
= 3.376.
Therefore, 64% of all children spend at least 3.376 hours per day unsupervised.
