the level of temperature of liquid in a thermometer is 26.52'c lower than the boiling poin. of water. what is the thermometer reading
The thermometer reading would be 73.48°C.
The boiling point of water is generally considered to be 100°C. According to the given information, the temperature of the liquid in the thermometer is 26.52°C lower than the boiling point of water. Therefore, to find the thermometer reading, we subtract 26.52 from 100.
100 - 26.52 = 73.48
Hence, the thermometer reading would be 73.48°C.
In this scenario, we are assuming that the thermometer is calibrated to measure temperature in Celsius. The boiling point of water at standard atmospheric pressure is 100°C, and the given information states that the liquid in the thermometer is 26.52°C lower than the boiling point.
By subtracting 26.52 from 100, we obtain a reading of 73.48°C.
Thermometers work by utilizing the principle that certain substances, such as mercury or alcohol, expand or contract with changes in temperature. The expansion or contraction is measured using a scale, which is marked with various temperature values.
In this case, the thermometer is calibrated in Celsius, so we refer to the Celsius scale. By subtracting 26.52 from 100, we find the temperature at which the liquid in the thermometer is settled, which is 73.48°C.

An agricultural company is trying to decide which type of fertilizer to use on its crops. The company concerned with the average yield on its crops as well as the variance of their yields. In a sample of 41 different fields with using fertilizer A, the average crop yield per acre is 185 tons with a standard deviation of 35 tons. In a separate sample of 61 different fields using fertilizer B, the average crop yield is 175 tons with a standard deviation of 28 tons. When testing the hypothesis that there is no difference between the average yields using the different fertilizers, if the test statistic is 1.53 and the critical value is 2.57 then what is your conclusion concerning the null hypothesis?
Answer:
We do not reject the null
Step-by-step explanation:
Given that :
Sample size, n = 41
Test statistic ; Zstatistic ;= 1.53
Critical value ; Zcritical ; = 2.57
The null hypothesis H0 ;
H0: μ1 - μ2 = 0
Alternative hypothesis, H1 ;
H1: μ1 ≠ μ2
Decision region :
Reject Null ; if |Zstatistic ≥ Zcritical|
Zstatistic > Zcritical
Result :
1.53 < 2.57
Zstatistic < Zcritical
Hence, we do not reject the null ; there is no significant evidence that there is difference in the average yield of the two samples.

The 99.5% confidence interval for the population mean is [74.681, 76.719].
How to calculate the confidence intervalConfidence Interval = (sample mean) ± (critical value) * (standard deviation / √sample size)
Using the given values:
Sample mean = 75.7
Standard deviation (σ) = 6.8
Sample size (n) = 353
Critical value (z) = 2.807
Confidence Interval = 75.7 ± 2.807 * (6.8 / √353)
In order to calculate the confidence interval accurately to 3 decimal places, we can substitute the values into the equation:
Confidence Interval = 75.7 ± 2.807 * (6.8 / √353)
Confidence Interval = 75.7 ± 2.807 * (6.8 / 18.794)
Confidence Interval = 75.7 ± 2.807 * 0.362

Describe Equation?In mathematics, an equation is a statement that shows that two expressions are equal to each other. An equation typically consists of two sides, the left-hand side (LHS) and the right-hand side (RHS), which are separated by an equals sign (=).
Equations are used to represent mathematical relationships and to solve problems in a variety of fields, including physics, engineering, economics, and finance. They can be linear or non-linear, and they may involve one or more variables.
Using the Pythagorean theorem in right triangle ABC, we have:
AC² = AB² + BC²
5² = y² + x²
x² = 25 - y²
Since angle BCA = 60 degrees, we know that:
tan(60) = y/x
√(3) = y/x
y = x√(3)
Substituting this into the equation x² = 25 - y², we get:
x² = 25 - 3x²
4x² = 25
x = √(25/4) = 5/2
And y = x√(3) = 5/2 ×√(3)
Therefore, AB = y = (5/2)√(3), BC = x = 5/2, and AC = 5.
Using the Pythagorean theorem in right triangle DEF, we have:
DF² = DE² + EF²
x² = y² + (4√3)²
x² = y² + 48
Since angle DEF = 60 degrees, we know that:
tan(60) = y/x
√(3) = y/x
y = x√(3)
Substituting this into the equation x² = y² + 48, we get:
x² = 3x² + 48
2x² = -48
x = √(-24) = 2i √(6)
And y = x √(3) = 2i√(18) = 2i 3√(2)
Therefore, DE = y = 2i 3√(2), EF = 4√3 and DF = x = 2i√6.

What is B^2+8b+7??
Can someone explain it step by step please?
Step-by-step explanation:
B^2+8b+7 is a quadratic expression. It can be factored as (b+7)(b+1).
To factor a quadratic expression, you can use the following steps:
1. Find two numbers that add up to the coefficient of the middle term (8) and multiply to the constant term (7).
2. Write the quadratic expression as a product of two binomials, with the two numbers you found in step 1 as the coefficients of the terms in each binomial.
In this case, the two numbers that add up to 8 and multiply to 7 are 7 and 1. So, we can factor B^2+8b+7 as follows:
(b+7)(b+1)
This means that B^2+8b+7 is equal to the product of (b+7) and (b+1).
Here is a step-by-step explanation of how to factor B^2+8b+7:
1. The coefficient of the middle term is 8.
2. The constant term is 7.
3. The two numbers that add up to 8 and multiply to 7 are 7 and 1.
4. Therefore, B^2+8b+7 can be factored as (b+7)(b+1).

a rectangular garden has dimensions of 5 feet by 12 feet. if the length and width of the garden are increased by the same amount, and the resulting area is 144 square feet, how much was each side increased?
Based on the data, we can infer that the difference in length after the garden increment is 4 feet on each side.
How to find how much the garden increased in length and width?To find how much the garden increased in length and width we must carry out the following procedure:
First of all we must calculate the area of the garden:
side * side = area5 * 12 = 60According to this result we know that the increase is more than half in the values. Therefore, we can add 3 or more feet to each side and recalculate the area of the garden.
5 + 3 = 812 + 3 = 158 * 15 = 120In this case we add 3 feet to each side and calculate the area that would give these side measurements 8 and 15. The area would be 120, you still wouldn't have enough length on the sides to have an area of 144.
5 + 4 = 912 + 4 = 1616 * 9 = 144In this case we add 4 feet on each side and calculate the area that would be given with these side measurements 9 and 16. The area would be 144, it would be the measurement mentioned in the statement.
