Write −0.35 as a fraction in simplest form.
Answer:It equals -7/20 because Here's how to convert 0.35 to a fraction...There is not much that can be done to figure out how to write 0.35 as a fraction, except to literally use what the decimal portion of your number, the .35, means. Since there are 2 digits in 35, the very last digit is the "100th" decimal place. So we can just say that .35 is the same as -35/100. The fraction -35/100 is not reduced to lowest terms. We can reduce this fraction to lowest terms by dividing both the numerator and denominator by 5. Why divide by 5? 5 is the Greatest Common Divisor (GCD) or Greatest Common Factor (GCF) of the numbers 35 and 100. So, this fraction reduced to lowest terms is -7/20. So your final answer is: 0.35 can be written as the fraction -7/20 Hope this helps... Plz mark me brainliest if the answer is correct... Stay safe and have a great weekend!!! :D
Step-by-step explanation:
The simplest fraction form id the number -35 is -7/100.
To write -0.35 as a fraction in simplest form, we need to convert the decimal number into a fraction.
Count the number of decimal places. In this case, we have two decimal places.
Write the decimal as a fraction with the denominator as a power of 10. Since we have two decimal places, the denominator will be 10^2, which is 100.
Place the decimal number over the denominator. In this case, -0.35/100.
Simplify the fraction by dividing both the numerator and denominator by their greatest common factor (GCF). In this case, the GCF of 35 and 100 is 5.
Dividing both the numerator and denominator by 5,
-0.35/100 = -35/500
Further simplify the fraction if possible. In this case, we can divide both the numerator and denominator by 5 again:
-35/500 = -7/100
So, -0.35 as a fraction in simplest form is -7/100.

Noise levels at 3 airports were measured in decibels yielding the following data:
108,146,160
Required:
a. Construct the 90% confidence interval for the mean noise level at such locations. Assume the population is approximately normal.
b. Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.
Answer:
a) The 90% confidence interval for the mean noise level at such locations
(112.46 , 163.54)
b) The critical value that should be used in constructing the confidence interval
Z₀.₁₀ = 1.645
Step-by-step explanation:
Step(i) :-
Noise levels at 3 airports were measured in decibels yielding the following data
108 146 160
Mean of given data
[tex]x^{-} = \frac{108+146+160}{3} = 138[/tex]
x : 108 146 160
x-x⁻ : -30 8 22
(x-x⁻ )² : 900 64 484
Variance σ ² = ∑(x-x⁻ )²/ n-1
= [tex]\frac{900+64+484}{3-1}= 724[/tex]
Standard deviation
σ = √724 = 26.90
Step(ii):-
The 90% confidence interval for the mean noise level at such locations
[tex](x^{-} - Z_{0.90} \frac{S.D}{\sqrt{n} } , (x^{-} + Z_{0.90} \frac{S.D}{\sqrt{n} } )[/tex]
The critical value that should be used in constructing the confidence interval
Z₀.₁₀ = 1.645
[tex](138 - 1.645 \frac{26.90}{\sqrt{3} } , (138 + 1.645 \frac{26.90}{\sqrt{3} } )[/tex]
( 138 - 25.54 , 138 + 25.54 )

Jessica has a four-sided die, a six-sided die, and a 12-sided die. She rolls the three dice once. Let Z be the number of fours showing. Find E[Z] using the indicator method.
Answer:
The value of E [Z] is 0.50.
Step-by-step explanation:
The expected value is computed using the formula:
[tex]E(X)=\sum x\cdot P(X= x)[/tex]
Denote the three dices as follows:
X₁ = a four-sided die
X₂ = a six-sided die
X₃ = a 12-sided die
Define the indicator variables as follows:
[tex]I_{1}=\left \{ {{1;\ X_{1}=4} \atop {0;\ X_{1}\neq 4}} \right. \\\\I_{2}=\left \{ {{1;\ X_{2}=4} \atop {0;\ X_{2}\neq 4}} \right. \\\\I_{3}=\left \{ {{1;\ X_{3}=4} \atop {0;\ X_{3}\neq 4}} \right.[/tex]
The probability of rolling a 4 in the three dices are as follows:
[tex]P(X_{1}=4)=\frac{1}{4}\\\\P(X_{2}=4)=\frac{1}{6}\\\\P(X_{3}=4)=\frac{1}{12}[/tex]
Compute the value of E [Z] as follows:
[tex]E(Z)=E(I_{1})+E(I_{2})+E(I_{3})[/tex]
[tex]=(1\times\frac{1}{4})+(1\times\frac{1}{6})+(1\times\frac{1}{12})\\\\=\frac{3+2+1}{12}\\\\=\frac{6}{12}\\\\=\frac{1}{2}\\\\=0.50[/tex]
Thus, the value of E [Z] is 0.50.

Suppose the temperature inside a three dimensional ball is proportional to the square root of the distance from the center. Find a formula for the average temperature in the ball. What is the limit of the average temperature as the ball gets larger?
Answer:
The formula for the average temperature in the ball is [tex]\bar T = \frac{2\cdot k\cdot R^{1/2}}{3}[/tex]. The limit of the average temperature for the ball does not exist.
Step-by-step explanation:
According to the statement, we have the following direct relationship:
[tex]T \propto \sqrt{r}[/tex]
[tex]T = k\cdot \sqrt{r}[/tex] (1)
Where:
[tex]T[/tex] - Temperature, measured in degrees Celsius.
[tex]r[/tex] - Distance from the center, measured in meters.
[tex]k[/tex] - Proportionality constant, measured in degrees Celsius per meter.
Under the assumption that ball is a continuous entity, we find that average temperature in the ball ([tex]\bar T[/tex]), measured in degrees Celsius, is represented by the following integral equation:
[tex]\bar T = \frac{1}{R}\cdot \int\limits^{R}_{0} {T(r)} \, dr[/tex] (2)
By applying (1) in (2), we find that:
[tex]\bar T = \frac{k}{R}\cdot \int\limits^{R}_{0} {\sqrt{r}} \, dr[/tex]
[tex]\bar T = \frac{2\cdot k}{3\cdot R}\cdot (R^{3/2})[/tex]
[tex]\bar T = \frac{2\cdot k\cdot R^{1/2}}{3}[/tex]
If the ball gets larger, then the limits associated to the average temperature diverges to the infinity as maximum exponent of the numerator of the rational function ([tex]n = \frac{1}{2}[/tex]) is greater than the maximum exponent of the denominator ([tex]n = 0[/tex]). Therefore, the limit of the average temperature for the ball does not exist.

Answer:x = 7
Step-by-step explanation:
Similar figures have sides that are proportional. Setting up a proportion for the sides of the figures will help solve for 'x':
Cross-multiply: 3(x + 1) = 6(x - 3)
Distribute: 3x + 3 = 6x - 18
Combine like terms: 21 = 3x
Solve for 'x': x = 7

In the statistic department of UCI, there are 60 graduate students in total, 45 PhD students and 15 master students. Among master students, 40% of them are international students. Among PhD students, 20% are international students. (a) What is the proportion of international students in the statistic department? (b) What is the proportion of master students among all domestic students.
Answer:
(a) The proportion of international students in the statistic department is 25%.
(b) The proportion of master students among all domestic students is 20%.
Step-by-step explanation:
The following can first be obtained from the question:
Total number of graduate students = 60
Number of PhD students = 45
Number of Master students = 15
Percentage of international students among the master students = 40%
Percentage of international students among the PhD students = 20%
Number of international master students = Number of Master students * Percentage of international students among the master students = 15 * 40% = 6
Number of international PhD students = Number of PhD students * Percentage of international students among the PhD students = 45 * 20% = 9
The questions can now be answered as follows:
(a) What is the proportion of international students in the statistic department?
This can be calculated as follows:
Total number of international students = Number of international master students + Number of international PhD students = 6 + 9 = 15
Total number of graduate students = 60
Proportion of international students in the statistic department = Total number of international students / Total number of graduate students = 15 / 60 = 0.25, or 25%
Therefore, the proportion of international students in the statistic department is 25%.
(b) What is the proportion of master students among all domestic students.
This can be calculated as follows:
Total number of graduate students = 60
Total number of international students = Number of international master students + Number of international PhD students = 6 + 9 = 15
Total number of domestic students = Total number of graduate students - Total number of international students = 60 - 15 = 45
Number of Master students = 15
Number of international master students = Number of Master students * Percentage of international students among the master students = 15 * 40% = 6
Number of domestic master students = Number of Master students - Number of international master students = 15 - 6 = 9
Proportion of master students among all domestic students = Number of domestic master students / Total number of domestic students = 9 / 45 = 0.20, or 20%
Therefore, the proportion of master students among all domestic students is 20%.
