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%

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.

A company in South Dakota manufactures hard hats used in the mining industry. They record measurements on all the hats they produce for quality control and planning purposes. The measurements they collect include hat size, circumference of the hat, and lengths of the major and minor axes. Meaning, the company wants to predict size of hat given the circumference. What is the response variable
Answer:
Response variable is the hats because it is the variable that is being predicted.
Step-by-step explanation:
A response variable is the subject/variable that responds to the various changes being made in an experiment. For example, if we are testing the effect of some drugs on people's emotions. The response variable here will be "emotions" because it is the subject that responds to the substance of the experiment.
Now, applying that to our question, the size of the hats will be the response variable because it is the variable in the experiment that the company is trying to predict from the circumference.
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.

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

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.

Which describes the cost to produce one item?
A. Benefit
B. Unit price
C. Fixed cost
D. Unit cost
Unit cost describes the cost to produce one item.
What is Cost?A cost is the value of money that has been used up to produce something or deliver a service
The unit cost is the cost associated with producing a single unit of a product or service.
It includes the direct and indirect costs of producing one item.
Direct costs can include the cost of raw materials, labor, and any other direct cost involved in the production of the item.
Indirect costs can include expenses like rent, utilities, equipment, and any other cost that is not directly associated with the production of a single unit, but is still necessary for the production process.
Hence, Unit cost describes the cost to produce one item.

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.

The area of the triangle below is 3/25 square feet. What is the length of the base? Express your answer as a fraction in simplest form.
2/5 ft is the height
Answer:
b = 0.6 ft
Step-by-step explanation:
area = 3/25
area = 1/2bh
3/25 = 1/2b(2/5)
1/2b = (3/25)/(2/5) = 15/50 = 3/10 or 0.3
b = 2(0.3) = 0.6 ft
The length of the base as a fraction in the simplest form is 3/5 feet.
What is a Triangle?Every three-sided polygon having three edges and three vertices is referred to as a triangle in geometry. The most important attribute of a triangle is that its interior angles sum to 180 degrees. This characteristic is known as the triangle's angle sum property. Every triangle has a length, base and height.
As per the given data:
Area of the triangle (A) = (3/25) sq feet
Height of the triangle (h) = (2/5) feet
A = (1/2) × base × height
(3/25) = (1/2) × base × (2/5)
base = (3 × 2 × 5)/(25 × 2)
base = 15/25
base = 3/5 feet
Hence, the length of the base as a fraction in the simplest form is 3/5 feet.
