A board game has 26 tiles labeled with alphabet letters. Players draw 1 tile at a time. Over 260 different drawings, how many times are players likely to draw either a vowel or the letter Y? Show your work.
Please help me, this is due soon and I don't understand it!
Answer: The probablty is is 41221/26 or 0.00669%
Step-by-step explanation:
Drawing tiles from the bag at one time is mathematically equivalent to drawing one tile 4 times inculding the vowel, without replacement.
If we get one of these 4 letters on draw 1, then on draw 2, we'll have 3 possible successful draws out of the 25 tiles left.
This pattern continues down to draw 4. Since each draw is independent, we just multiply the probabilities together:
Your goal this year is to earn a B or better in Algebra
class. If you do, your parents said they would give you
$200. Write an inequality to represent the grades you
can earn and receive money from your parents for it.
Then explain the graph for the inequality. Hint;
Remember you cannot earn higher than a 100 in any
class.
Your score must be at least 80 for your parent to give you $200
The inequality that represents the your score is 80 <= x <=100
How to determine the inequalty?In a grading system;
A score of 80% would earn a student a B grade
This means that:
If you want to earn a B or better in Algebra class, then you have to score at least 80 in the Algebra class i.e 80 or above
So, the inequality is:
x >= 80
Given that the score cannot exceed 100; the inequality becomes
x >= 80 and x <=100
Rewrite as:
80 <= x and x <=100
Combine both inequalities
80 <= x <=100
Hence, the inequality that represents the student score is 80 <= x <=100

Abram needs to build a window frame. He needs 2 pieces of lumber that are 4 3/4 feet long and 2 more that are 3 1/3 feet long. How much lumber does Abram need in all?
Answer:
16 1/6 feet of lumber
Step-by-step explanation:
- 2 pieces of lumber that are 4 3/4
- 2 pieces of lumber that are 3 1/3
4 3/4 * 2 = 9 1/2
3 1/3 * 2 = 6 2/3

Answer:
Set of numbers: 5, 6, 8, 10, 11, 15, 17, 25, 29, 29, 41, 50, 51, 52, 52, 54, 56, 57, 57
Mean: 32.89
Median: 29
Mode: 29, 52, 57
Range: 52
Step-by-step explanation:
The numbers are already ordered for us, so to find the mean, we need to add the numbers and divide the sum by the number of numbers. This gives us about 32.89.
The median is the middle number in the set, so right in the middle of the set is 29.
The range is the biggest number minus the smallest number, which would be 57-5 = 52.
Mode is the value or values in the data set that occur most frequently, which would be 29, 52, and 57, because they all occur the same number of times.

A measure of central tendency (measure of center) is a value that attempts to describe a set of data by identifying the central position of the data set (as representative of a "typical" value in the set).
What is a measure of centre?
A measure of central tendency (measure of center) is a value that attempts to describe a set of data by identifying the central position of the data set (as representative of a "typical" value in the set). We are familiar with measures of central tendency called the mean, median and mode.
Measures of variation describe the width of a distribution. They define how spread out the values are in a dataset. They are also referred to as measures of dispersion/spread.

2 lines intersect to form 4 angles. Clockwise, from top left, the angles are: x degrees, 105 degrees, z degrees, y degrees.
Which equations are true for the values of x, y, and z in the figure? Select all that apply.
x° + 105° = 180°
x° = z°
105° – y° = 90°
x° + y° + z° = 180°
180° – z° = y°
x° + y° = 105°
Eli is a dental sales representative who wants to distribute 16 brochures and 14 pamphlets to local dental offices. He wants to deliver the same combination of brochures and pamphlets to each office, without having any materials left over. What is the greatest number of dental offices Eli can distribute materials to?
Answer:
14/16 can be reduced to 7/8
that's about it, he can visit 2 dental offices.
both numbers can't be split up into nicer packets, like 3 or 5. only the 14 is divisible by 7, but not the 16.
this means he can't leaves 3 there, 3 there, because that will leave as rest
other scenario: he throws 2 brochures right into the recycling bin and visits up to 14 dental offices
Answer:
The answer is two offices are the greatest number he can distribute to.
2 is the reciprocal of 1/2
And 1/2 is our multiplier.
As we are not provided his maximum amount of brochures and pamphlets held, we are given one set of numbers being ratio 16:14
Step-by-step explanation:
16+14 = 30 combined brochures and pamphlets.
1/2 x 16 = 8 brochures maximum each dental office
and 1/2 x 14 = 7 pamphlet maximum each dental office
ratio = 8:7 combination shown as ratio
therefore reciprocal of 1/2 = 2

y=-1/3+5
Step-by-step explanation:
Notice that the answers they give you to choose from are all lines in slope y-intercept form, it would be very simple to just find the answer finding yourself the slope and y-intercept of the line in question.
Since they give you two points and for the line, use them to find the slope of the line that goes through them, with the formula:
Therefore, the slope of the line must be
Now, find the y-intercept (b) using the general form of a line with the given slope:
Use one of the given coordinate points to request that the line passes through it. For example, through the point (-3,6) (when x = -3, y must be 6):
then the y-intercept must be 5. Therefore our line is : which appears listed as your second choice.

Camille unpacked 24 boxes and then took a break. She had completed 40% of the unpacking. How many total boxes did she need to unpack?
PLZ SHOW WORK**
If 24 boxes = 40 percent
we can say that
12 boxes is 20%
since she finished 40% and now (100%-40% = 60%) we know she needs to unpack 60 %.
As i said:
24 box = 40%
12 box = 20 %
add em up and
36 box = 60%
She needed to unpack 60 boxes( 36+24 = 60)

In Ponce De Leon Park, there is a flag pole that is exactly 50 feet tall. Nearby, there is a pine tree that appears to be nearly as tall as the flag pole. On a sunny afternoon, the flag pole is casting a 15-foot-long shadow on the ground. The pine tree is casting a 12-foot-long shadow on the ground at the same time.
Answer:
10 feet higher.
Pine tree measure = 40 feet in height
Step-by-step explanation:
This is because the Flag pole of 50 feet in measure cast a shadow of 15feet and nearby to the pine tree (meaning same dilation would occur for such shadow) where pine tree shadow is given measure of 12 feet.
Flag Pole multiplier = 50 / 15 = 3 1/3
Pine Tree true measure = 12 x 3 1/3 = 40 feet in height
Solve for x in the diagram below
Answer:
x = 12
Step-by-step explanation:
The 2 angles add up to 90 degrees, so 3x + x + 42 = 90
3x + x + 42 = 90
Subtract 42 from both sides:
3x + x = 48
3x + x = 4x, so
4x = 48
Divide both sides by 4:
x = 12
