Answer:
Number of cheesecakes local bakery expects to sell in a day = 14 (Approx.)
Step-by-step explanation:
Given:
Number sold Probability xP(x)
0 0.1 0
5 0.19 0.95
10 0.05 0.5
15 0.14 2.1
20 0.52 10.4
Find:
Number of cheesecakes local bakery expects to sell in a day
Computation:
Number of cheesecakes local bakery expects to sell in a day = Sum of xP(x)
Number of cheesecakes local bakery expects to sell in a day = 0 + 0.95 + 0.5 + 2.1 + 10.4
Number of cheesecakes local bakery expects to sell in a day = 13.95
Number of cheesecakes local bakery expects to sell in a day = 14 (Approx.)
Write 0.4 : 6 as a whole number ratio in it's simplest from.
______________________________________
The answer is 1/15.
______________________________________
Answer: 0.4 : 6 = 1 : 15
Step-by-step explanation: Change values to whole numbers.
Convert any decimal numbers to integers by multiplying both sides by 101 = 10 to eliminate all, 1, decimal places.
We then have:
0.4 : 6 = 4 : 60
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 4 and 60 is 4
Divide both terms by the GCF, 4:
4 ÷ 4 = 1
60 ÷ 4 = 15
The ratio 4 : 60 can be reduced to lowest terms by dividing both terms by the GCF = 4 :
4 : 60 = 1 : 15
Therefore:
0.4 : 6 = 1 : 15

Solve: 4 (x + 2.5) = 48
Answer:x=19/2
Step-by-step explanation:
4(x+2.5)=48
Step 1: Simplify both sides of the equation.
4(x+2.5)=48
(4)(x)+(4)(2.5)=48(Distribute)
4x+10=48
Step 2: Subtract 10 from both sides.
4x+10−10=48−10
4x=38
Step 3: Divide both sides by 4. 4x/4 = 38/4 = 19/2
Answer:
4(x + 2.5) = 48.
4x + 4 x 2.5 = 48.
4x + 10 = 48.
4x + 10 -10 = 48 -10
4x = 38
Divide both sides by 4.
X = 9.5.
X = 10 if approximated.

Students in a high school mathematics class decided their term project would be a study of the strictness of
the parents or guardians of students at their school. Their goal was to estimate the proportion of students in
their school who thought of their parents or guardians as “strict”. They do not have time to interview all
students in the school, so they plan to obtain data from a sample of students. Which of the following
describes the best design for this study?
A. Simulation
B. Observational study
C. Survey
D. Experiment
Answer:
The answer is observational study
The best design for this study will be an Observational study. Then the correct option is B.
What is the Observational study?An epidemiological survey draws conclusions from a sample of a population in disciplines like epidemiology, social sciences, psychology, and statistics when the regression coefficient is not within the researcher's control due to ethical considerations or practical limitations.
An analysis of the strictness of the parents or guardians of pupils at their school was chosen by students in a high school mathematics class as the topic for their term project. They wanted to determine how many pupils at their school saw their parents or guardians as "tight." Since they lack the time to speak with every kid in the school, they intend to gather information from a representative group of pupils.
The best design for this study will be an Observational study. Then the correct option is B.

is the domain of this situation?
Answer:
This means that the domain of this situation is [tex]m \in [0,200][/tex], that is, you can talk between 0 and 200 minutes in the month.
Step-by-step explanation:
Ace Telecommunications charges $0.12 per minute of phone use plus a monthly service fee of $8.00 for the phone service.
This means that the cost of speaking for m minutes is given by:
[tex]C(m) = 8 + 0.12m[/tex]
You can talk for no more than 200 minutes in a month.
This means that:
[tex]m \leq 200[/tex]
What is the domain of this situation?
The domain of a function is the input variable.
In function C(m), m is the input variable, and since you can talk for no more than 200 minutes in a month, the restriction for the input is [tex]m \leq 200[/tex].
This means that the domain of this situation is [tex]m \in [0,200][/tex], that is, you can talk between 0 and 200 minutes in the month.

A car has a velocity of 25 m/s and a mass of 3500 kg. What is the cars momentum?
Answer:
87,500 kg-m/s
Step-by-step explanation:
Momentum = Mass * velocity
3500*25 = 87,500
Answer:
87,500 kg.m/s.
Step-by-step explanation:
The formula for finding momentum is p= mv, meaning that to find the momentum of something, you need to multiply the velocity by the mass of the object. So, doing the math:
p=mv
p=3,500x25
p=87,500.

A tank contains 100 kg of salt and 1000 L of water. A solution of a concentration 0.05 kg of salt per liter enters a tank at the rate 99 L/min. The solution is mixed and drains from the tank at the same rate.
Required:
a. Find the amount of salt in the tank after 3.5 hours.
b. Find the concentration of salt in the solution in the tank as time approaches infinity.
Correct question is;
A tank contains 100 kg of salt and 1000 L of water. A solution of a concentration 0.05 kg of salt per liter enters a tank at the rate 9 L/min. The solution is mixed and drains from the tank at the same rate.
Required:
a. Find the amount of salt in the tank after 3.5 hours.
b. Find the concentration of salt in the solution in the tank as time approaches infinity.
Answer:
A) y(3.5) = 40.11 kg of salt
B) Concentration as time approaches infinity = 0.05 kg/l
Step-by-step explanation:
We are given;
Mass of salt; m_s = 50 kg
Volume of water; v_w = 1000 L
Rate at which salt enters = 0.05 kg/L × 9 L/min. = 0.45 kg/min
Since the solution drains at same rate as it enters, then;
Rate at which salt goes out = 9y/1000
Where y is the concentration in the tank.
Thus, the differential equation of the amount of water in the tank will be;
dy/dt = Rate at which salt enters - Rate at which salt goes out
dy/dt = 0.45 - (9y/1000)
Simplifying this gives;
dy/dt = (9/1000)(50 - y)
Rearranging, we have;
dy/(50 - y) = dt(9/1000)
Integrating both sides gives;
In(50 - y) = 9t/1000 + A
If we do exponents of both sides, we will get;
50 - y = Ae^(-9t/1000)
At initial conditions, y = 0 and t = 0.
Thus;
A = 50
Thus, quantity of salt in tank will be written as;
50 - y = 50e^(-9t/1000)
Making y the subject gives;
y = 50 - 50e^(-9t/1000)
At t = 3.5 hours = 210 minutes
y = 50 - 50e^(-9 × 180/1000)
y(3.5) = 40.11 kg of salt
As t approaches infinity, it means t will be zero. Thus;
y = 50 - 50e^(-9 × 0/1000)
y = 50 kg
Concentration = 50/1000 = 0.05 kg/l

Looking out from a balcony, the angle of elevation to the top of the next building is
approximately 22 degrees. The angle of depression to the bottom of the building is
approximately 29 degrees. If the building is 200 feet away, how tall is it?
Answer:
191.67 feets
Step-by-step explanation:
From. The attached picture :
Height x can be obtained using trigonometry :
Tan 22 = x / 200
0.4040262 = x / 200
x = 0.4040262 * 200
x = 80.805245 feets
For height, y :
Tan 29 = x / 200
0.5543090 = x / 200
y = 0.5543090 * 200
y = 110.86181 feets
Building height = x + y
Building height = 80.805245 + 110.86181 = 191.67 feets

Find the measure of angle A:
Find the measure of angle B:
Answer:
Measure of angle A is 65 degrees and measure of angle B is 37 degrees.
Step-by-step explanation: First add all of the degrees of excluding x (4+(-9)) which is -5. Then subtract that from 180 since that is the sum of all the angles in a triangle which gives you 185. Then divide it by the number of "x's" that there are which is 5 which gives you 37. So angle B is x which is 37 degrees and angle a is 2(37)-9 which is 65 degrees. Hope this helps.
Mr. and Mrs. Doran have a genetic history such that the probability that a child being born to them with a certain trait is 0.8. If they have three children, what is the probability that exactly two of their three children will have that trait? Round your answer to the nearest thousandth
Answer:
0.384 = 38.4% probability that exactly two of their three children will have that trait.
Step-by-step explanation:
For each children, there are only two possible outcomes. Either they have the trait, or they do not. The probability of a child having the trait is independent of any other child. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Mr. and Mrs. Doran have a genetic history such that the probability that a child being born to them with a certain trait is 0.8.
This means that [tex]p = 0.8[/tex]
Three children:
This means that [tex]n = 3[/tex]
What is the probability that exactly two of their three children will have that trait?
This is P(X = 2).
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{3,2}.(0.8)^{2}.(0.2)^{1} = 0.384[/tex]
0.384 = 38.4% probability that exactly two of their three children will have that trait.

Six chicken nuggets have 204 calories. How many calories are in 9 chicken nuggets
Answer:
306 calories
Step-by-step explanation:
By looking at the problem, we can conclude the number of chicken nuggets and the calories are directly related, when the amount of chicken nuggets go up, the calories also go up, proportionally. Because of this, we can set up an equation:
6 / 204 = 9 / x
Where x is the amount of calories in 9 chicken nuggets.
Now, we can simplify by cross multiplying:
6x = 1836
x = 306 calories
Answer:
