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.

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.

Step-by-step explanation:
[tex] composite =cuboid + 3d \: triangle \\ = (l \times w \times h) + ( \frac{1}{2} \times b \times h \times w) \\ = (12 \times 5 \times 7) + ( \frac{1}{2} \times (15 - 12) \times 7\times 5) \\ = (12 \times 5 \times 7) + ( \frac{1}{2} \times 3 \times7 \times 5) \\ [/tex]
The correct expression for finding the volume of the composite figure is 7×12×5 + (1/2)×3×7×5.
Correct option is (D).
What is Volume?Any three-dimensional solid's volume is the space it takes up. The shapes of these solids include cube, cuboid, cone, cylinder, and sphere.
As per the given diagram:
The dimensions of the composite figure are given.
Volume of the composite figure
= Volume of the cuboid + Volume of the triangular prism
= l×b×h + (1/2)×base×height×length
From the diagram:
= 12×7×5 + (1/2)×(15 - 12)×7×5
= 12×7×5 + (1/2)×3×7×5
= 7×12×5 + (1/2)×3×7×5
Hence, the correct expression for finding the volume of the composite figure is 7×12×5 + (1/2)×3×7×5.

At a school social, parents attended with their children, Everyone had a choice between a sweet snack and a salty snack. Here is a two-way table showing the number of adults and children who made each choice of snack.
Fill in the Blanks in the table with relative frequency by row. Round to the nearest percent!!!
Answer:
Adult sweet snack: 39%
Adult salty snack: 61%
Child sweet snack: 71%
Child salty snack: 29%
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%

Just curious, I want to see who can get this. tooooootttalllllly know it already
Assume that we have two variables a and b, and that: a = b
Multiply both sides by a to get: a2 = ab
Subtract b2 from both sides to get: a2 - b2 = ab - b2
This is the tricky part: Factor the left side (using FOIL from algebra) to get (a + b)(a - b) and factor out b from the right side to get b(a - b). If you're not sure how FOIL or factoring works, don't worry—you can check that this all works by multiplying everything out to see that it matches. The end result is that our equation has become: (a + b)(a - b) = b(a - b)
Since (a - b) appears on both sides, we can cancel it to get: a + b = b
Since a = b (that's the assumption we started with), we can substitute b in for a to get: b + b = b
Combining the two terms on the left gives us: 2b = b
Since b appears on both sides, we can divide through by b to get: 2 = 1

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.

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.

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
For 40 days in the summer, you are working in a small, student-run company that sends out merchandise with university branding to alumni around the world. Every day, you take a sample of 50 shipments that are ready to be shipped to the alumni and inspect them for correctness. Across all days, the average percentage of incorrect shipments is 5 percent. What would be the center line for a p-chart? multiple choice 40 50 0.05 2.5 None of these
Answer:
[tex]Center\ Line = 0.05[/tex]
Step-by-step explanation:
Given
[tex]n = 50[/tex] --- daily samples
[tex]days = 40[/tex]
Required
Determine the center line of the p-chart
The question states that, in all the 40 days; the average percentage of incorrect shipments is 5%
And the center line of a p chart is a measure of the expected value of all proportions
This implies that:
[tex]Center\ Line = 5\%[/tex]
[tex]Center\ Line = 0.05[/tex]
