Answer:
Square B 9 × 7.5
Step-by-step explanation:
The computation is shown below:
9 × 7 = 63 > 55
8 × 5 = 40 < 55
5 × 10 = 50 < 55
As it can be seen that in only one condition the total of square feet is less and in the other conditions the total of square feet is more
Therefore the option Square B is correct
And, the rest of the options are incorrect

Answer:
Step-by-step explanation:
Definitions
Prime number: A whole number greater than 1 that cannot be made by multiplying other whole numbers.
Prime Factorization: Prime numbers that multiply together to make the original number.
The first few prime numbers are: 2, 3, 5, 7, 11, 13, 17, ...
To find which prime numbers multiply together to make 252, begin by dividing 252 by the first prime number, 2:
⇒ 252 ÷ 2 = 126
As 126 is not a prime number, we need to divide again.
⇒ 126 ÷ 2 = 63
As 63 is not a prime number, and 63 is not divisible by 2, try dividing it by the next prime number, 3:
⇒ 63 ÷ 3 = 21
As 63 is not a prime number, divide again.
⇒ 21 ÷ 3 = 7
As 7 is a prime number, we can stop.
Therefore, 252 is the product of:
⇒ 252 = 2 × 2 × 3 × 3 × 7
As 2 and 3 appear twice, we can write these using exponents:
⇒ 252 = 2² × 3² × 7

A restaurant manger surveyed a random sample of costumers to determine which drink they prefer. Fourteen chose tea and 36 chose soda.
Based on the results , we have to find how many of the 275 customers can be expected to prefer soda?
total customers x = 275
customers chose soda y= 36
customers chose tea z= 14
therefore out of 275 customer who prefer soda = (x * y)/(y+z)
Based on the given conditions, formulate: [tex]: \frac{275 * 36}{14+36} \\\\[/tex]
Calculate the product or quotient:[tex]\frac{9900}{14+36}[/tex]

Step-by-step explanation:
a match box has length x cm, width x +1 cm and height 3 cm. express its surface area as a function of x
Answer:
2x² + 14x + 6
Step-by-step explanation:
A match box is in the shape of a right rectangular prism so we can use the formula for the surface area of such a solid
A=2(wl+hl+hw)
where l = length, w=width and h = height
Substituting l = x, w = x+1 and height = 3 we get
wl = x(x + 1) = x² + x
hl = 3x
hw = 3(x + 1) = 3x + 3
So A = 2( x² + x + 3x + 3x + 3)
A = 2(x² + 7x + 3)
A = 2x² + 14x + 6

Here are the statistics for the high temperatures in a city during October:
mean of 65.3 degrees Fahrenheit
median of 63.5 degrees Fahrenheit
standard deviation of 9.3 degrees Fahrenheit
IQR of 7.1 degrees Fahrenheit
Recall that the temperature C, measured in degrees Celsius, is related to the temperature F, measured in degrees Fahrenheit, by C=5/9(F−32).
a. Describe how the value of each statistic changes when 32 is subtracted from the temperature in degrees Fahrenheit.
b. Describe how the value of each statistic further changes when the new values are multiplied by 5/9.
c. Describe how to find the value of each statistic when the temperature is measured in degrees Celsius.
Answer:
a. Describe how the value of each statistic changes when 32 is subtracted from the temperature in degrees Fahrenheit.
a) The mean will change and other quantities remain same.
b) The mean, standard deviation and IQR change.
c) The standard deviation and IQR change.
a. When 32 is subtracted from the temperature in degrees Fahrenheit:
The mean would change by subtracting 32 from the original mean of 65.3.The median would remain the same since subtracting a constant value does not affect the relative order of the data points.The standard deviation would remain the same since it is a measure of dispersion and does not depend on the shift of the data.The IQR would remain the same since it is based on the order statistics (including the median) and is not affected by a constant shift.b. When the new values (obtained after subtracting 32) are multiplied by 5/9:
The mean would change by multiplying the new mean by 5/9.The median would remain the same since scaling by a constant value does not affect the relative order of the data points.The standard deviation would change by multiplying the new standard deviation by 5/9 since it is a measure of dispersion and scales with the data.The IQR would change by multiplying the new IQR by 5/9 since it is based on the order statistics and scales with the data.c. To find the value of each statistic when the temperature is measured in degrees Celsius:
The mean and median would remain the same since the Celsius scale and Fahrenheit scale have a linear relationship, and shifting or scaling the data does not affect their relative values.The standard deviation would change by multiplying the new standard deviation by 5/9 since it scales with the data.The IQR would change by multiplying the new IQR by 5/9 since it scales with the data.Learn more about IQR here:

a researcher records the repair cost for 1313 randomly selected stereos. a sample mean of $85.52$85.52 and standard deviation of $10.81$10.81 are subsequently computed. determine the 90�% confidence interval for the mean repair cost for the stereos. assume the population is approximately normal. step 1 of 2 : find the critical value that should be used in constructing the confidence interval. round your answer to three decimal places.
The mean repair cost for the stereos is (79.47, 91.56) with a 90% confidence interval.
What is the critical factor?The critical factor for a 90% confidence interval for the true mean repair cost for stereos is given by;
Critical factor = (x-μ)/(s/√n)
where, x = sample mean repair cost
s = standard deviation of a sample
n = sample of stereos
μ = critical value
We have been given that a researcher records the repair cost for 13 randomly selected stereos. a sample mean of $85.52 and a standard deviation of $10.81 are subsequently computed.
Since we don't know the population standard deviation, we used t statistics to create the 90% confidence interval in this case.
So, the 90% confidence interval for the true mean repair cost, μ is ;
⇒ P(-2.015 < t₅ < 2.015) = 0.90
{As the critical value of t at 5 degrees of freedom are -2.015 & 2.015 with P = 5%}
⇒ P(-2.015 < (x-μ)/(s/√n) < 2.015) = 0.90
⇒ P(-2.015×(s/√n) < (x-μ) < 2.015×(s/√n)) = 0.90
⇒ P(x - 2.015×(s/√n) < μ < x + 2.015×(s/√n)) = 0.90
90% confidence interval for
⇒ μ = (x - 2.015×(s/√n) , x + 2.015×(s/√n))
Here, x = $85.52, s = $10.81, and n = 13
⇒ μ = (85.52 - 2.015×(10.81/√13) , 85.52 + 2.015×(10.81/√13))
⇒ μ = (79.47, 91.56)
Hence, the mean repair cost for the stereos is (79.47, 91.56) with a 90% confidence interval.
