Step-by-step explanation:
The required integer that represents paying a bill of $55 would be "55".
What are Integers?Integers are defined as the collection of Whole Numbers Integers is represented by the symbol Z.
Integers are numbers that can be written without a fractional or decimal component, such as -3, -2, -1, 0, 1, 2, 3, and so on. They include the positive whole numbers (1, 2, 3, etc.), the negative whole numbers (-1, -2, -3, etc.), and zero.
We have to write an integer to represent the given situation.
As per the question, the integer represents the amount of money being paid in dollars.

Step-by-step explanation:
Residences of U.S. Citizens According to the U.S. Census, 67.5% of the U.S. population were born in their state of residence. In a random sample of 203 Americans, what is the probability that fewer than 126 were born in their state of residence? Round the final answer to at least four decimal places and intermediate -value calculations to two decimal places.
P ( X < 126)=?
Answer:
P(X < 126) = 0.0418
Step-by-step explanation:
To solve this question, we use the binomial approximation to the normal to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
Can be approximated to a normal distribution, using the expected value and the standard deviation.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
Normal probability distribution
Problems of normally distributed distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
When we are approximating a binomial distribution to a normal one, we have that [tex]\mu = E(X)[/tex], [tex]\sigma = \sqrt{V(X)}[/tex].
Sample of 203, 67.5% of the U.S. population were born in their state of residence.
This means that [tex]n = 203, p = 0.675[/tex]
So, for the approximation:
[tex]\mu = E(X) = np = 203*0.675 = 137.025[/tex]
[tex]\sigma = \sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{203*0.675*0.325} = 6.67[/tex]
What is the probability that fewer than 126 were born in their state of residence?
Using continuity correction, this is P(X < 126 - 0.5) = P(X < 125.5), which is the pvalue of Z when X = 125.5. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{125.5 - 137.025}{6.67}[/tex]
[tex]Z = -1.73[/tex]
[tex]Z = -1.73[/tex] has a pvalue of 0.0418
So
P(X < 126) = 0.0418

(CO 2) A random selection from a deck of cards selects one card. What is the probability of selecting a spade
Answer:
[tex]P(Spade) = 0.25[/tex]
Step-by-step explanation:
Given.
In a deck, there are:
[tex]Cards = 52[/tex]
[tex]Spade= 13[/tex]
Required
Determine the probability that a selected card is a spade
This is represented as: P(Spade) and it is calculated using:
[tex]P(Spade) = \frac{Spade}{Cards}[/tex]
Substitute 13 for Spade and 52 for Cards
[tex]P(Spade) = \frac{13}{52}[/tex]
[tex]P(Spade) = 0.25[/tex]
Hence, the required probability is 0.25
Is it linear or exponential
Answer: exponential
Step-by-step explanation: the x in the equation is an exponent
Answer:
Exponential.
Step-by-step explanation:
The function shown is h(x) = 8(1/3)^x.
Essentially this is showing powers of 1/3 multiplied by 8.
This would not make a line, as it involves an exponent.
As a result, this function is exponential, because of the exponent involved.
What is 1/2 divided by 1/3
Answer:
[tex]\frac{3}{2}[/tex]
Step-by-step explanation:
[tex]\frac{1}{2}[/tex] ÷ [tex]\frac{1}{3}[/tex]
The reciprocal of [tex]\frac{1}{3}[/tex] is 3, so finding the reciprocal will replace the division sign with a multiplication sign.
= [tex]\frac{1}{2}[/tex] x 3
= [tex]\frac{3}{2}[/tex] or 1[tex]\frac{1}{2}[/tex] or 1.5

Answer:
a) The equation of the straight line passing through the origin and having slope m=-5
y = -5x
b) The equation of the straight line in slope-intercept form
y = 2 x -1
Step-by-step explanation:
Step(i):-
We know that the equation of the straight line passing through the point (x₁, y₁) and having slope 'm'
y - y₁ = m(x-x₁)

Gabby picked out a handful of jellybeans. She chose 8 red, 3 yellow, 5 black, and 2 orange. What is the ratio of yellow jellybeans to total jellybeans?
Answer:
The ratio of yellow jellybeans to total jellybeans is 1:6.
Step-by-step explanation:
The ratio of yellow jellybeans to total jellybeans is given by the number of yellow jellybeans divided by the number of total jellybeans.
In this question, we have that:
There are 3 yellow jellybeans.
In total, there are 8 + 3 + 5 + 2 = 18 total jellybeans.
So the ratio is:
3/18 = 1/6 = 1:6
The ratio of yellow jellybeans to total jellybeans is 1:6.

Use the graph to write the explicit rule of the arithmetic sequence.
A)
ƒ(n) = 3 + 1(n – 1)
B)
ƒ(n) = 7 + 3(n – 1)
C)
ƒ(n) = 7 + (–2)(n – 1)
D)
ƒ(n) = 2 + (–7)(n – 1)
Answer:
[tex]f_n=7+\left(-2\right)\left(n-1\right)[/tex]
Therefore, option C is true.
Step-by-step explanation:
From the graph, we get the sequence
7, 5, 3, 1, ...
Here,
a₁ = 7 is the first element.
An arithmetic sequence has a constant difference 'd' and is defined by
[tex]f_n=a_1+\left(n-1\right)d[/tex]
computing the differences of all the adjacent terms
[tex]5-7=-2,\:\quad \:3-5=-2,\:\quad \:1-3=-2[/tex]
The difference between all the adjacent terms is the same and equal to
[tex]d=-2[/tex]
substituting a₁ = 7 and d = -2 in the nth term of the sequence
[tex]f_n=a_1+\left(n-1\right)d[/tex]
[tex]f_n=7+\left(-2\right)\left(n-1\right)[/tex]
Therefore, option C is true.

A weather balloon is 529 meters above the ground. Two weather stations, A and B, monitor the balloon’s progress. A weather balloon is 529 meters above the ground. Weather stations A and B are on the ground to form a triangle. A horizontal line is drawn at the top of the triangle to form angle v on the left and angle w on the right. The angle formed with A is x and the angle formed with B is y. A vertical line is drawn from the weather balloon to the ground to form a right angle and split the distance between A and B into 2 parts. The distance from A to the vertical line is 229 meters, and the distance between the vertical line and point B is 347 meters. Compare the measures of the different angles of elevation and depression that are labeled in the diagram. Which statements are true? Check all that apply.
