at a local zoo, adult visitors pay $3 and children visitors pay $1. on one day, the zoo collected a total of $720. if the zoo had 420 visitors tgat day, how many adults and how many children visited?
Answer:
150 adults, 270 kids.
Step-by-step explanation:
We can make a set of equations with the given information:
Adult=X
Kids=Y
3x+1y=720
x=y=420
420-X=Y
3x+420-x=720
2x+420=720 720-420=300
300/2=150
X=150, there were 150 adult visitors which means there are 270 children
According to a Gallup poll in October 2015, having young children at home greatly influences whether women in the U.S. prefer to stay at home or work outside of it. More than half of women, 57%, who have a child younger than 18 would ideally like to stay home and care for their house and family, while 58% of those without young children would rather work outside the home. Having young children makes little difference in men's preferences, with close to three-quarters preferring to work regardless of their parenting status. Gallup states that their method has a margin of error of 0.031.
1. Give a point estimate for the proportion of all US women with a child under 18 that would like to stay at home.
2. Give an interval estimate for the proportion of all US women with a child under 18 that would like to stay at home.
3. What is the difference between a point estimate and an interval estimate?
A. A point estimate only tells us the best guess for theparameter; an interval estimate is more likely to be close to the parameter than a single point.
B. A point estimate only tells us the best guess for the parameter; an interval estimate also gives us a measure of how far away that guess is likely to be from the parameter.
C. A point estimate only tells us the parameter value; an interval estimate also gives us a measure of how far away that guess is likely to be from the parameter.
D. A point estimate only tells us the parameter value; an interval estimate also gives us a plausible range of values for the statistic.
E. A point estimate only tells us the parameter value; an interval estimate also gives us a plausible range of values for the parameter.

[tex]\^p = 0.57[/tex]
b
[tex]0.539 <p< 0.601[/tex]
c
The correct option is C
Step-by-step explanation:
The percentage of women who would like to stay at home and take care of their family due to the fact that they have a child younger than 18 is [tex]p_1 = 57\%[/tex]
The percentage of women who would rather work outside their home due to the fact that they don't have children is [tex]p_2 = 58\%[/tex]
The margin of error is [tex]E = 0.031[/tex]
Gnerally the point estimate of all US women with a child under 18 that would like to stay at home is mathematically represented as
[tex]\^ p = \frac{57}{100}[/tex]
[tex]\^ p = 0.57[/tex]
Gnerally the interval estimate for the proportion of all US women with a child under 18 that would like to stay at home is mathematically as
[tex]\^ p -E < p < \^ p +E[/tex]
=> [tex]0.57 -0.031 <p< 0.57 + 0.031[/tex]
=> [tex]0.539 <p< 0.601[/tex]

A single six sided die is rolled. Find the probability of rolling a number more than 2
Answer:
2/3
Step-by-step explanation:
outcomes are (1,2,3,4,5,6)
No. Of outcomes =6
no. More than 2 are : (3,4,5,6)
Therefore the probability is 4/6 = 2/3
The probability of rolling a number more than 2 is 2/3
What is probability?Probability is the measure of the chances of an event happening.
Probability of an event is calculated by dividing the number of favorable outcomes of the given event divided by the total number of given outcome
Let E be an event , Probability of the event E,
P(E) = outcomes favorable to E/ total outcomes
In an experiment a single six sided die is rolled
Therefore the possible outcomes are {1,2,3,4,5,6}
Total number of possible outcomes = 6
Let E be the of rolling a number greater than 2
Possible outcomes in E are {3,4,5,6}
number of favorable outcomes of E , n(E) = 4
The probability of E , P(E) = n(E) / total number of outcomes = 4/6 = 2/3
Therefore the probability of rolling a number more than 2 is 2/3 = 0.667

Nico and Albert are finishing up a science project. They measured the length in inches of three insects. They also found the average measurement of two more insects from a website. Bug Length Bug Length in inches Lady bug StartFraction 3 Over 8 EndFraction Ant One-fourth Firefly StartFraction 7 Over 8 EndFraction Honeybee 0.8 Deer tick 0.2 Which list shows the lengths from shortest to longest? 0.2, one-fourth, StartFraction 3 Over 8 EndFraction, 0.8, StartFraction 7 Over 8 EndFraction 0.2, one-fourth, StartFraction 3 Over 8 EndFraction, StartFraction 7 Over 8 EndFraction, 0.8 One-fourth, 0.2, StartFraction 3 over 8 EndFraction, StartFraction 7 Over 8 EndFraction, 0.8 0.8, one-fourth, StartFraction 3 Over 8 EndFraction, 0.2, StartFraction 7 Over 8 EndFraction
Answer:
Step-by-step explanation:
Given the length of the bugs as shown;
Lady bug = 3/8
Ant = 1/4
Firefly = 7/8
Honey bee = 0.8
Deer tick = 0.2
Before we arrange the length in ascending order (shortest to longest), we will have to represent them in percentage.
Lady bug = 3/8×100
= 300/8
= 37.5%
Ant = 1/4×100
Ant = 25%
Firefly = 7/8 × 100
Firefly = 87.5%
Honey bee = 0.8×100
Honey bee = 80%
Deer tick = 0.2×100
Deer tick = 20%
On rearranging in ascending order:
20%, 25%, 37.5%, 80%, 87.5%
Based on the insect
Deer tick, Ant, ladybug, honey bee, Firefly
Based on their length:
0.2, 1/4, 3/8, 0.8, 7/8

the probability that any one egg is not spoiled in a carton of 6 eggs is 75%
Answer:
This might seem like an obvious thing to do, but Murphy points out that the date printed on the packaging isn't always an expiration date. A carton of eggs may not always need to be thrown out as soon as the date passes. The date is usually just an indicator of the egg's freshness.
"The expiration dates are not expiration dates. Sometimes they are, but most of the time, the printed date is a best used-by date or sell-by date," Murphy tells INSIDER. "So, that does not always mean that the eggs have gone bad. Food can be bad before the date. Eggs and other dairy products are temperature sensitive. If you left your carton of eggs out on the counter for an extended period of time, the eggs would actually go bad before the date."
Per Murphy, "bad," however, means that you shouldn't eat the egg because it has the potential to make you sick. But, eggs can still be fresh even if they have passed their sell-by or used-by date.
"The fresher an egg is, like a lot of things, the better it tastes. In terms of freshness, a company can put a sell-by date or best used-by date on the carton. There is no regulation on that. The date is a good indicator of freshness," said Murphy. "The closer you get to the date, the less fresh the eggs are going to be. But, just because you've hit that date or gone beyond it doesn't mean that the eggs are necessarily bad."
Step-by-step explanation:
The easiest way to tell whether or not a carton of eggs has gone bad is to do the float test. To conduct the float test, take one egg and place it in a bowl of room temperature water, according to Murphy. If the egg sinks to the bottom and lies flat on its side, it is still fresh. If the egg stands up on its end like it's standing up, then the egg has gone bad.
"When an egg is first laid and it's truly really fresh, it's completely full there is very little air inside. But, egg shells are porous. So, as time goes by the inside starts to evaporate and is replaced by air," said Murphy. "The amount of air in the egg depends on what happens to the egg when it is dropped into water. Generally, if an egg actually floats that's the point when an egg has gone bad."

Find the differential of the function
a. y=x4sin(9x)
b. y=x4sin(9x).
Answer:
We want to find:
[tex]y'*dx = dy[/tex]
Where:
[tex]y = x^4*sin(9x)[/tex]
Remember that when we have a function like:
f(x) = g(x)*h(x)
The derivation gives:
f'(x) = g'(x)*h(x) + g(x)*h'(x)
In this case we can define:
f(x) = y
g(x) = x^4
h(x) = sin(9x)
These functions are easy to differentiate:
g'(x) = 4*x^3
h'(x) = 9*cos(9*x)
Then we have:
[tex]y' = \frac{dy}{dx} = 4x^3*sin(9x) + x^4*9cos(9x)[/tex]
Then we can write:
[tex]dy = (4x^3*sin(9x) + 9x^4*cos(9x))dx[/tex]

A ramp has a horizontal distance of 10 feet and a vertical rise of 3 feet. Find the length of the ramp. Round to the nearest tenth.
Answer:
Step-by-step explanation:
Tye length of the ramp can be gotten using Pythagoras theorem.
Horizontal distance = 10ft.
Vertical distance = 3ft
Length of the ramp² = 10²+3²
Length of the ramp² = 100+9
Length of the ramp² = 109
L² = 109
L =√109
L = 10.44ft
Hence the length of the ramp is 10.4ft to the nearest tenth
• The volume of a cube is 17 cubic inches. What expression represents the length of one side of the cube?
(remember the cube problem from the review yesterday!)
If the volume of a cube is an integer value of cubic inches, when will the length of one side of the cube be
irrational?
Step-by-step explanation:
The volume of a cube is 17 cubic inches.
The formula used to find the volume of a cube is given by :
[tex]V=x^3[/tex]
x is the side of the cube
[tex]x=(V)^{1/3}\\\\x=(17)^{1/3}\\\\x=2.57\ \text{inches}[/tex]
The fraction that cannot be written in the form of p/q is irrational no. If the cube root a number is not possible, then the length is considered to be irrational.
