One day on Sesame Street, a friendly rabbit brought big bird a tube of toothpaste that contained one gallon of toothpaste. If a regular toothpaste cost $1.39 for 2.7 ounce tube what is the value of the sesame steeet tube to the nearest cent?
The sesame street tube bought by the blue bird costs $177.92 which contained one gallon of toothpaste.
Given,
cost of regular toothpaste = $1.39 for 2.7 ounce tube
But the bird took a tube of toothpaste that contained one gallon of toothpaste.
One gallon = 128 ounces
∴the total price at which the toothpaste is brought = price of normal toothpaste × one gallon(128 ounces)
= 1.39 × 128
=$177.92
Here we can observe that a gallon contains 128 ounces. so we need to multiply to the initial cost of the toothpaste to get the final amount of the toothpaste bought by the bird.
Hence the price at which the bird bought the toothpaste is $177.92

The area of the square LMNP is 50 square units
How to determine the area of the square?The circumference of the circle is given as:
C = 10π
Circumference is calculated as:
C = 2πr
So, we have:
2πr = 10π
Divide by 2π
r = 5
This represents the length OM
The length PM is calculated as:
PM = 2 * OM
This gives
PM = 2 * 5
PM = 10
The length (PN) of the square is then calculated as:
PM = PN√2
This gives
10 = PN√2
Square both sides
100 = PN^2 * 2
Divide by 2
50 = PN^2
Rewrite as:
PN^2 = 50
Hence, the area of the square LMNP is 50 square units

Answer:
1/40 or 0.025
Step-by-step explanation:
the weight of baby el is 200
the weight of mama el is 8000
take 200/8000 and simplify.
if you divide the top by 200 then divide the bottom by 200
200 divided by 200 is 1
8000 divided by 200 is 40
so the simplest fraction is 1/40

Lowest score earned to be qualified for an interview is 92.82
X : Marks scored in interview
X ~ N(80,100)
Here we need to find x such that P(X > x) = 0.10
using standard normal table,
we get P( z > 1.282) = 0.10
It's always easy to use Standard normal distribution to solve questions of normal distribution because standard normal is special case of normal distribution with mean 0 and standard deviation 1.
To convert x (which follows Normal distribution) to standard normal use: [tex]\frac{x-\mu}{\sigma} \sim N(0,1)[/tex]
so, [tex]z = 1.282 = \frac{x-\mu}{\sigma}[/tex]
hence,
[tex]x = 1.282 * \sigma + \mu \\x = 1.282 * 10+_80 \\x = 92.82 \\[/tex]

Levi needed to get his computer fixed. He took it to the repair store. The technician at
the store worked on the computer for 5.5 hours and charged him $59 for parts. The
total was $361.50. Which equation could be used to determine c, the cost of labor per
hour?
Answer:
$55
Step-by-step explanation:
Let c = cost of labour per hour
1) Set up an equation, where hours is denoted by c.
5.5c + 59 = 361.50
5.5c = 361.50 - 59
5.5c = 302.50
c = 302.50/5.5
c = 55
Therefore, the technician took $55 per hour.

When the value of the population standard deviation is unknown, we estimate it with ________ to conduct inference about a population mean.
sample standard deviation.
the sample standard deviation is used to estimate σ in the confidence interval formula. The quantity 1.96σ/ √n is often called the margin of error for the estimate.
Standard deviation (or σ) is a measure of how much the data extends from the mean. A low standard deviation means that the data is gathered around the mean, and a high standard deviation means that the data is more distributed.
Standard deviation is important because it shows how the values are distributed in a particular dataset. Whenever I analyze a dataset, I am interested in finding the following metrics: The center of the dataset. The most common ways to measure the "intermediate" are mean and median.

Solve the system of equations. 5x y = 9 3x 2y = 4 (−2, 5) (1, 4) (2, −1) (4, −4)
The solution of the system of equations that is given is (2,-1).
Given a system of equations are 5x+y=9 and 3x+2y=4.
A system of linear equations (or linear system) is a collection of one or more linear equations involving the same variables. A solution to a linear system is an assignment of values to the variables such that all the equations are simultaneously satisfied.
The given equations are
5x+y=9 ......(1)
3x+2y=4 ......(2)
Here, the substitution method is used to solve the system of equations.
Find the value of y from equation (1) by subtracting 5x from both sides.
5x+y-5x=9-5x
y=9-5x
To find the value of x substitute the value of y in equation (2).
3x+2(9-5x)=4
Apply the distributive property a(b+c)=ab+ac as
3x+2×9-2×5x=4
3x+18-10x=4
Combine the like terms on the left side as
-7x+18=4
Subtract 18 from both sides and get
-7x+18-18=4-18
-7x=-14
Divide both sides by -7 and get
(-7x)÷(-7)=(-14)÷(-7)
x=2
Substitute the value of x in equation (1) and get
5(2)+y=9
10+y=9
Subtract 10 from both sides
10+y-10=9-10
y=-1
Hence, the solution of system of equations 5x+y=9 and 3x+2y=4 is (2,-1).

0.5(4x - 8) = 2x + 5
There is no value of x that makes the equation 0.5(4x - 8) = 2x + 5 true. The solution is "no solution."
To solve for the value of x in the equation 0.5(4x - 8) = 2x + 5, follow these steps:
Step 1: Distribute the 0.5 on the left side of the equation:
0.5 * 4x - 0.5 * 8 = 2x + 5
Simplify:
2x - 4 = 2x + 5
Step 2: To isolate the variable term "x" on one side of the equation, move the constant terms to the other side. In this case, subtract 2x from both sides:
2x - 2x - 4 = 2x - 2x + 5
Simplify:
-4 = 5
Step 3: The equation simplifies to -4 = 5, which is not true. This means that the equation has no solution, and there is no value of x that satisfies the equation.
Therefore, there is no value of x that makes the equation 0.5(4x - 8) = 2x + 5 true. The solution is "no solution."

B) P(X>=7)=[tex]C_{10,7} (0.57)^{7} (0.43)^{3} +C_{10,8} (0.57)^{8} (0.43)^{2} +C_{10,9} (0.57)^{9} (0.43)^{1} +C_{10,10} (0.57)^{10} (0.43)^{0}[/tex]
=0.18012+0.081+0.0258+0.0036
=0.29
C)P(X<=5)=[tex]C_{10,1} (0.57)^{1} (0.43)^{9} +C_{10,2} (0.57)^{2} (0.43)^{8} +C_{10,3} (0.57)^{3} (0.43)^{7} +C_{10,4} (0.57)^{4} (0.43)^{6} +C_{10,5} (0.57)^{5} (0.43)^{5}[/tex]
=0.00285+0.0146205+0.0432+0.126+0.21168
=0.3983.
Hence the probability that the number of residents that recognize the brand is not 4 is 0.86 , the probability that at least 7 people will recognize the brand is 0.29 and the probability that at most 5 people will recognize the coffee shop is 0.39.
