In science class, Savannah measures the temperature of a liquid to be 50∘ Celsius. Her teacher wants her to convert the temperature to degrees Fahrenheit. What is the temperature of Savannah's liquid to the nearest degree Fahrenheit
Final answer:
To convert the temperature of Savannah's liquid from Celsius to Fahrenheit, use the equation °F = (°C × 9/5) + 32. Savannah's temperature in Celsius is 50°, so her temperature in Fahrenheit is 122°F.
Explanation:
To convert the temperature from Celsius to Fahrenheit, you can use the equation:
°F = (°C × 9/5) + 32.
In this case, Savannah's temperature in Celsius is 50°. Using the equation, we can calculate her temperature in Fahrenheit as:
°F = (50 × 9/5) + 32 = 122°F.
Therefore, the temperature of Savannah's liquid to the nearest degree Fahrenheit is 122°F.
Savannah's liquid, initially measured at 50°C, converts to 122°F using the formula F = C x (9/5) + 32.
Explanation:Converting Celsius to FahrenheitTo convert the temperature from degrees Celsius to degrees Fahrenheit, we use the conversion formula: F = \( C \times \frac{9}{5} + 32 \), where F is the temperature in degrees Fahrenheit and C is the temperature in degrees Celsius.
In Savannah's case, she measured the temperature as 50°C. Applying the conversion formula:
First, multiply the Celsius temperature by \( \frac{9}{5} \)50 \times \frac{9}{5} = 90Then, add 32 to this result to find the Fahrenheit temperature.90 + 32 = 122Therefore, the temperature of Savannah's liquid to the nearest degree Fahrenheit is 122°F.
A sample of size 40 is taken from an infinite population whose mean and standard deviation are 68 and 12 respectively. the probability that the sample mean is larger than 70 equals:
To solve this problem, we can use the z statistic to find for the probability. The formula for z score is:
z = (x – u) / s
Where,
u = the sample mean = 68
s = standard deviation of the samples = 12
x = sample value = 70
In this case, what is asked is the probability that the sample mean is larger than 70, therefore this corresponds to the right of z on the graph of normal distribution.
z = (70 – 68) / 12
z = 2 / 12
z = 0.17
Therefore finding for P at z ≥ 0.17 using the standard distribution tables:
P (z = 0.17) = 0.5675
But this is not the answer yet since this is the P to the left of z. Therefore the correct one is:
P (z ≥ 0.17) = 1 - 0.5675
P (z ≥ 0.17) = 0.4325 = 43.25%
The probability that the sample mean is larger than 70 is 43.25%
The probability that the sample mean is larger than 70 for a sample size of 40 from a population with a mean of 68 and standard deviation of 12 is approximately 14.69%.
To determine this probability, we can use the Central Limit Theorem (CLT), which states that the distribution of sample means will be approximately normal if the sample size is large enough (n ≥ 30 is a common benchmark).
The standard error of the mean is calculated using the formula:
SE = σ / √n
Where σ is the population standard deviation and n is the sample size.
In this case:
σ = 12
n = 40
Therefore,
SE = 12 / √40 ≈ 1.8974
The z-score is calculated using the formula:
z = (M - μ) / SE
Where M is the sample mean,
μ is the population mean,
SE is the standard error.
Given,
μ = 68
M = 70
Therefore,
z = (70 - 68) / 1.8974 ≈ 1.054
Using the z-table, we find the probability that a z-score is less than 1.054 is approximately 0.8531.
However, we need the probability that the sample mean is greater than 70, so we subtract this from 1,
1 - 0.8531 ≈ 0.1469
Thus, the probability that the sample mean is larger than 70 is approximately 0.1469, or 14.69%.
How many cubic feet of space is there in a warehouse that is 610 feet wide by 140 feet deep and has an 18 foot ceiling?
Final answer:
The warehouse has a volume of 252,000 cubic feet, calculated using the corrected dimensions of 140 feet in length, 100 feet in width, and an 18-foot ceiling.
Explanation:
To calculate the volume of a warehouse, we use the formula for the volume of a rectangular prism, which is length × width × height. However, the question contains a typo about the width of the warehouse.
We are informed that the correct width is 100 feet, not 610 feet.
Given the corrected dimensions (140 feet by 100 feet with an 18 foot ceiling), we can now calculate the volume of the warehouse.
Volume = length × width × height
= 140 feet × 100 feet × 18 feet
= 252,000 cubic feet.
Therefore, the warehouse has a volume of 252,000 cubic feet of space.

Step-by-step explanation:
In Algebra, the following notations have to be considered.
Algebra is a branch of mathematics that deals with the computation of numbers irrespective of the signs involved.
- × - = +
+ × - = -
- × + = -
+ × + = +
Therefore,
1. 6.314 - 9.77 = -3.456
2. -5.118 - (-4.1) = -5.118 + 4.1 = -1.018
3. x + y for x = 75.9 and y = 2.65.
This requires substitution
75.9 + 2.65 = 78.55
4. -x + y for x = 75.9 and y = 2.65
= -75.9 + 2.65
= -73.25

To find the total number of different sets of five courses, multiply the number of choices for each course category: 2 (Humanities) × 2 (Sociology) × 6 (Science) × 6 (Math) × 8 (Music). This results in 1152 different sets of five courses.
To determine the number of different sets of five courses possible, we need to consider the choices available for each category:
- Humanities: 2 choices
- Sociology: 2 choices
- Science: 6 choices
- Math: 6 choices
- Music: 8 choices
The total number of different sets of five courses can be found by multiplying the number of choices in each category together. Here is the calculation:
2 × 2 × 6 × 6 × 8
Let's calculate this step-by-step:
1. 2 × 2 = 4
2. 4 × 6 = 24
3. 24 × 6 = 144
4. 144 × 8 = 1152
Therefore, the number of different sets of five courses possible is: 1152

the ratio of the corresponding side of two regular polygons is 3:4 the area of the larger polygon is 320 m squared what is the area of the smaller polygon?
The area of the smaller polygon with a side ratio of 3:4 is 180 m2 for the smaller polygon.
When dealing with the areas of similar polygons, if the ratio of corresponding sides is given, such as 3:4 in this case, the ratio of their areas is the square of the ratio of their sides. This is because the area is a two-dimensional measure, so each dimension is scaled by the ratio.
Given that the area of the larger polygon is 320 , we establish that the scale factor is 3 for the smaller polygon and 4 for the larger one.
To find the area of the smaller polygon, we use the fact that the ratio of the areas is (3/4)2 = 9/16.
This means that the area of the smaller polygon is 9/16 times the area of the larger polygon. Therefore, focusing on the comparison of areas, we calculate:
Area of smaller polygon = (9/16) x Area of larger polygon
= (9/16) x 320
Area of smaller polygon = 180
How many square meters are in 350 square centimeters?
To convert 350 square centimeters to square meters, divide by the conversion factor that 1 square meter equals 10,000 square centimeters, resulting in 0.035 square meters.
Explanation:To convert 350 square centimeters to square meters, we should remember that 1 square meter is equal to 10,000 square centimeters because 1 meter is equal to 100 centimeters and for area, we need to square that conversion (100 cm × 100 cm).
We start with the given quantity of 350 square centimeters. Then, we use the conversion factor 1 square meter is 10,000 square centimeters to perform the calculation, which gives us:
350 cm² × (1 m² / 10,000 cm²) = 0.035 m².
Therefore, 350 square centimeters is equal to 0.035 square meters.
