ms.vellejo has these cans of soup in her cabinet 1 can of tomato soup 4 cans of chicken soup 3 cans of cheese soup 2 cans of beef soup ms.velljo will randomly choose one can of soup what is the probililty that she will choose a can of beef or chicken soup
Answer:
There is a 40% chance that she will choose a can of beef soup, a 20% chance that she will choose a can of chicken soup, and a combined 60% chance that she will choose a can of beef or chicken soup.
Step-by-step explanation:
Since Ms. Vellejo has 1 can of tomato soup, 4 cans of chicken soup, 3 cans of cheese soup and 2 cans of beef soup in her cabinet, and she will randomly choose one can of soup, to determine what is the probililty that she will choose a can of beef or chicken soup, the following calculation must be performed:
1 + 4 + 3 + 2 = 10
Beef soup = 2 cans = 2/10 = 0.2 = 20%
Chicken soup = 4 cans = 4/10 = 0.4 = 40%
20 + 40 = 60
Thus, there is a 40% chance that she will choose a can of beef soup, a 20% chance that she will choose a can of chicken soup, and a combined 60% chance that she will choose a can of beef or chicken soup.
A population of 384 prairie dogs live in an area of 16 km2. What is the the population density?
Question 13 options:

what is 2/3 - 5/12 equal to
Answer:
8/12-5/12=3/12 or 1/4 :)
Answer:
1/4 = 0.25
Step-by-step explanation:
2/3 - 5/12
Least common multiple of 3 and 12 is 12. Convert 2/3 and 5/12 to fractions with denominator 12.
8/12 - 5/12
Since 8/12 and 5/12 have the same denominator, subtract them by subtracting their numerators.
8-5/12
Subtract 5 from 8 to get 3.
3/12
Reduce the fraction 3/12 to lowest terms by extracting and canceling out 3.

15% of customers that come to your
taco truck order two tacos. If 300 guests
come to your store, how many of them
will you expect to order two tacos?
Answer:
Number of customers (double taco)= 45
Step-by-step explanation:
Giving the following information:
Double taco order rate= 15% = 0.15
Total number of customers= 300
To calculate the number of customers that order two tacos, we need to use the following formula:
Number of customers (double taco)= Double taco order rate*total number of taco
Number of customers (double taco)= 0.15*300
Number of customers (double taco)= 45
Raina received a $90 gift card for a coffee store. She used it in buying some coffee that's cost $7.38 per pound. After buying the coffee, she had $53.10 left on her card. How many pounds of coffee did she buy?
Answer:
5 lbs
Step-by-step explanation:
90 - 53.10 = 36.90
She spent $36.90 on coffee. Since it cost $7.38 per pound, we can divide the total cost by 7.38 to figure out how many pounds she bought:
36.90 / 7.38 = 5
Raina bought 5 pounds of coffee.

NK Karate Club offers two different fees for their karate classes. Club members are charged a one-time membership fee of $32 and pay $4 per class. Non-members pay $8 per class. Let y represent the number of karate classes attended.
a. Write an expression to represent the cost for a non-member to attend y classes.
b. Write an expression to represent the cost for a member to attend y classes.
c. Set the two expressions equal to each other and solve the equation to determine how many classes result in the same cost for a member and non-member.
Answer:
a) x = 8y
b) x = 32 + 4y
c) 8y = 32 + 4y
Step-by-step explanation:
-4y -4y
8y = 32 + 4y
÷4 ÷4
4y = 32
y = 32
The expression represents the cost for a non-member to attend y classes is x=8y.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
Given that, Club members are charged a one-time membership fee of $32 and pay $4 per class. Non-members pay $8 per class.
Let y represent the number of karate classes attended.
a) The cost for a non-member to attend y classes is
Non-members pay $8 per class.
So, the expression is 8y
b) The cost for a member to attend y classes is
Club members are charged a one-time membership fee of $32 and pay $4 per class.
Now, the expression is 32+4y
c) Set the two expressions equal to each other, that is
8y =32 + 4y
8y-4y=32
4y=32
y=8
Therefore, the expression represents the cost for a non-member to attend y classes is x=8y.

(Simplify your answer. Type your answer in standard form, using integer
coefficients with A20.)
Answer:
[tex]x = 8[/tex]
Step-by-step explanation:
Given
See attachment for graph
Required
The line graph
First, consider the following points on the graph.
[tex](x_1,y_1) = (8,0)[/tex]
[tex](x_2,y_2) = (8,8)[/tex]
First, calculate the slope.
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{8-0}{8-8}[/tex]
[tex]m = \frac{8}{0}[/tex]
[tex]m =[/tex] undefined
Since, the slope is undefined; we simply consider only the value of x.
The line equation is:

9x+10y =1 9x-6y=-15 solve using elimination
Answer:
I. x = -1
II. y = 1
Step-by-step explanation:
Given the following algebraic expressions;
9x + 10y = 1 .......equation 1
9x - 6y = -15 ......equation 2
To solve using the elimination method, we would subtract eqn 1 from eqn 2.
(9x - 9x) + (-6y - 10y) = (-15 - 1)
0x - 16y = -16
-16y = -16
16y = 16
y = 16/16
y = 1
Next, we would find the value of x;
From eqn 1;
9x + 10y = 1
Substituting the value of y, we have;
9x + 10(1) = 1
9x + 10 = 1
9x = 1 - 10
9x = -9
x = -9/9
x = -1
which of the following is a quadrantal angle
Question:
Which of the following is a quadrantal angle?
a) π/2 b) π/3 c) 2π/3 D) 4π/5
Answer:
[tex](a)\ \frac{\pi}{2}[/tex]
Step-by-step explanation:
Required
Which of a to d is a quadrantal angle
An angle is said to be quadrantal if and only if the angle has its terminal side on the x or y axis.
Such angles (in degrees) are: 90, 180, 270, etc.
So, we have:
[tex](a)\ \frac{\pi}{2}[/tex]
[Convert to degrees]
[tex]\frac{\pi}{2} = \frac{180}{2}[/tex]
[tex]\frac{\pi}{2} = 90[/tex]
Hence:
[tex](a)\ \frac{\pi}{2}[/tex] is a quadrantal angle

If you invest 3,500 in a savings account that pays 4% simple interest how much will the new balance be after including interest?
Answer:
New balance = 3640
Step-by-step explanation:
Given the following data;
Interest rate = 4% = 4/100 = 0.04
Principal = 3500
To find the new balance;
First of all, we would find the amount at the interest rate;
New amount = interest rate * principal
New amount = 0.04 * 3500
New amount = 140
Now, to find the new balance;
New balance = principal + new amount
New balance = 3500 + 140
New balance = 3640
LifeCharge Batteries claims that their batteries last an average of 210 hours when used in a hand held gaming system, with a standard deviation of about 9 hours. An independent quality control company took a sample of 34 batteries, and used the same hand held gaming system that LifeCharge used to record the time the batteries lasted.
1. Assuming the claim is true, what is the probability that the value of the sample mean is greater than 251.7 hours.
2. The sample mean was found to be 251.7, what does this say about the claim?
A. The sample mean is quite far off from the mean claimed, casting doubt on the current mean.
B. The sample mean is sufficiently close to the mean claimed, supporting the current mean.
C. The sample mean found does not truly support nor cast doubt on the current mean.
Answer:
The answer is "0.0023 and Choice a"
Step-by-step explanation:
In point a:
The central limit theorem:
[tex]\mu_{X}= 250\\\\\sigma_{X}=\frac{\sigma}{\sqrt{n}}=\frac{6}{\sqrt{100}} =0.6\\\\P(\bar{X}>251.7)\\\\=P(z>\frac{251.70-250}{0.6})\\\\=P(z>2.83)\\\\=1-0.9977\\\\=0.0023[/tex]
In point b:
The chance is lower than 0.05. This means that it is very rare to see the average sample above 251.8 if the argument is valid, that is why the means of the sample is far away from the common claimed and casts doubt on the actual mean.

Determine the third sides
(7): We have
[tex]b = 5[/tex]
[tex]a = 15[/tex]
[tex]c=??[/tex]
To find c, we make use of Pythagoras theorem
[tex]c^2 = a^2 + b^2[/tex]
[tex]c^2 = 5^2 + 15^2[/tex]
[tex]c^2 = 250[/tex]
[tex]c = \sqrt{250[/tex]
[tex]c = 15.81[/tex]
(8): We have
[tex]c = 20[/tex]
[tex]a = 12[/tex]
[tex]b = ??[/tex]
To find c, we make use of Pythagoras theorem
[tex]c^2 = a^2 + b^2[/tex]
[tex]20^2 = 12^2 + b^2[/tex]
[tex]400 = 144 + b^2[/tex]
