Is x+y is an algebraic expression?
Answer:
It depends on the definition of "algebraic expression", and especially the meaning of "algebraic" you take to use in your context. If you talk from a high-school perspective, then yes, x+y−π is an algebraic expression, because... well, it looks like algebra and has algebraic-looking characters.

Answer:
It landed at a height of 14 feet
Step-by-step explanation:
Given
[tex]y = -\frac{1}{8}x^2 +4x[/tex] --- Path of a t-shirt
[tex]3y = 2x - 14[/tex] --- height of bleachers
Required
Height when t-shirts land in bleachers
[tex]3y = 2x - 14[/tex]
Make y the subject
[tex]y = \frac{2}{3}x - \frac{14}{3}[/tex]
Substitute [tex]y = \frac{2}{3}x - \frac{14}{3}[/tex] in [tex]y = -\frac{1}{8}x^2 +4x[/tex]
[tex]\frac{2}{3}x - \frac{14}{3} = -\frac{1}{8}x^2 +4x[/tex]
Multiply through by 24
[tex]16x- 112 = -3x^2 +96x[/tex]
Express as:
[tex]3x^2 + 16x -96x- 112 = 0[/tex]
[tex]3x^2 -80x- 112 = 0[/tex]
Using a calculator:
[tex]x = 28[/tex] or [tex]x = -\frac{4}{3}[/tex]
x can not be negative:
So:
[tex]x = 28[/tex]
Substitute [tex]x = 28[/tex] in [tex]y = -\frac{1}{8}x^2 +4x[/tex] to calculate the height it landed
[tex]y = -\frac{1}{8} * 28^2 + 4 * 28[/tex]
[tex]y = 14[/tex]

The law of cosines tells you ...
e² = d² +f² -2df·cos(E)
e² = 196 +81 -252cos(52°) ≈ 121.853
e ≈ √121.853 ≈ 11.04

Step-by-step explanation:
this is the answer
The Complete table with relative frequency by row is shown below.
What is Relative Frequency?The ratio (fraction or proportion) of the number of times a data value occurs in the set of all outcomes to the total number of outcomes is referred to as the relative frequency.
The number of times an event occurs divided by the total number of events occurring in a particular scenario is described as relative frequency. The relative frequency calculation is as follows:
Relative Frequency = Subgroup Frequency/Total Frequency.
The Relative Frequency table is:
Adult (Sweet Snack) : 57/ 145 x 100 = 39.31%
Adult (Salty Snack) = 88/145 x 100 = 60.68%
Child(Sweet Snack) : 77/108 x 100 = 71.29%
Child (Salty Snack) = 31/108 x 100 = 28. 70%

There are an infinite number of answers for this equation:
63 - X = 34
Answer: No, the answer is 29, this is false.
Step-by-step explanation: 63-x=34
subtract 63 from both sides
34-63= -29
-x=-29
divide both sides by the negative and you get 29
plug in 29 for x, 63-29=34

Find the area of the shaded region in the image below. Write your answer as a simplified polynomial in standard form.
Answer:
6x^2+17x+9
Step-by-step explanation:
you have to subtract the area of the white rectangle from the area of the entire rectangle
to find the area of the inner rectangle do (2x-3)*(x+1)=2x^2-3x+2x-3=2x^2-x-3
to find the area of the entire rectangle do (4x+6)*(2x+1)=8x^2+12x+4x+6=8x^2+16x+6
(8x^2+16x+6)-(2x^2-x-3)=8x^2+16x+6-2x^2+x+3=6x^2+17x+9
A honeybee colony that contains 50,000 bees in late fall
may have only 10,000 bees at the end of winter. What
percent of the bees live through the winter season?
a. 5%
b. 20%
c. 25%
d. 50%
Answer:
The answer is B. 20%
Step-by-step explanation:
50,000×0.20= 10,000
10,000÷50,000= 0.20
0.2= 20%
Given:
Number of bees in late fall = 50,000 bees
Number of bees after winter = 10,000 bees
To find:
Percent of bees that live through winter
Steps:
To find the percent of bees that live through winter,
percent of bees that live through winter = [tex]\frac{Number 'of' bees' after' winter}{Number 'of' bees' in' late 'fall}*100[/tex]
= [tex]\frac{10,000}{50,000}*100[/tex]
= [tex]\frac{1}{5}*100[/tex] (the zeros get canceled out)
= [tex]\frac{100}{5}[/tex]
= 20%
Therefore only b) 20% of bees survive through winter.

Evelyn is making bows from blue and white ribbon. She uses 6 in. of blue ribbon
for every 9 in. of white ribbon. Evelyn has 82 in, of blue ribbon and 114 in. of white
ribbon. Which color of ribbon will she run out of first? Explain.
Answer:
White
Step-by-step explanation:
W: 114/9 ≈ 12.67 9-inch ribbons
12.67(6) = 76 < 82
Evelyn will run out of white ribbon first as she can use it for 12 times compared to 13 times.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, She uses 6 in. of blue ribbon and has a total of 82 inches,
So, The number of times she can use is,
= (82/6) times.
= 13.66 times.
Similarly, The number of times she can use the white ribbon is,
= (114/9) times.
= 12.66 times.
Therefore, She will run out of white ribbons first.

Why would anyone want a bound on the margin of error of a point estimate p-hat or x-bar?
Explain this in terms of the population distribution, and also explain in terms of the sampling distribution of the point estimate.
Here are some notes i have from some sources i hope these notes will be able to help you achieve the grade you wanted to good luck!
-The bound on error of estimation, B , associated with a confidence interval is (z critical value) ·(standard error of the statistic) . ... Sample Size The sample size required to estimate a population proportion to within an amount B with 95% confidence is The value of may be estimated by prior information.
-P-value and margin of error are not same.
-A margin of error tells you how many percentage points your results will differ from the real population value. For example, a 95% confidence interval with a 4 percent margin of error means that your statistic will be within 4 percentage points of the real population value 95% of the time.
-The margin of error determines how reliable the survey is or how reliable the results of the experiment are. ... This is captured in statistics as margin of error. The higher the margin of error, the less likely it is that the results of the survey are true for the whole population.
-Population distribution means the pattern of where people live. World population distribution is uneven. Places which are sparsely populated contain few people. Places which are densely populated contain many people.
