in an Internet service of 50 MBPS speed a mobile application file is downloaded in 1 minutes find the sizes of the file in GB
Answers
Answer:
Size in GB = 0.0061 GB (rounded to 4 decimal places)
Step-by-step explanation:
First, let's convert the internet speed from Mbps to GB per minute:
50 Mbps = 50/8 MBps (since 1 byte = 8 bits)
= 6.25 MBps
Therefore, the size of the file downloaded in 1 minute can be calculated as:
Size = Speed x Time
Size = 6.25 x 1
Size = 6.25 MB
To convert this to GB, we divide by 1024 since there are 1024 MB in 1 GB:
Size in GB = 6.25 / 1024
Size in GB = 0.0061 GB (rounded to 4 decimal places)

Answers
Answer:
Givens
AB + BC = AC
AB = 2(x + 1)
BC = 3x + 1
AC = 4(x + 2)
Substitute and Solve
AB + BC = AC
2(x + 1) + 3x + 1 = 4(x + 2) Remove the brackets on the left
2x + 2 + 3x + 1 = 4(x + 2) Collect the like terms on the left
5x + 3 = 4(x + 2) Remove the brackets on the right.
5x + 3 = 4x + 8 Subtract 4x from both sides.
5x - 4x + 3 = 8
x + 3 = 8 Subtract 3 from both sides
x =8 - 3
x = 5
Answers
AB=2(5 + 1) = 2 * 6 = 12
BC = 3x + 1 = 3*5 + 1 = 15 + 1 = 16

5. Lakita's test scores are 87, 96, 81, and 89.
What score does she need on the last test in
order to average 90 on her tests?
[5]
Answers
Answer: 97
Step-by-step explanation:
Average: All the numbers added divided by the number of numbers
Start adding the smallest grade in her notes: 87+96+81+89+81= 434/5= 86.8
Keep adding 1 to the last grade until you find a number that gives us an average of 90.
87+96+81+89+97+ 450
Then divide it by the amount of grades
450/5= 90

Answers
16 quarts is equal to 4 gallons.
The correct option is C.
To convert quarts to gallons, we divide the number of quarts by 4 (since there are 4 quarts in a gallon).
Given that we have 16 quarts, we can calculate:
16 quarts / 4 quarts/gallon
= 4 gallons
Therefore, 16 quarts is equal to 4 gallons.

A one-tailed hypothesis test with the t statistic Antisocial personality disorder (ASPD) is characterized by deceitfulness, reckless disregard for the well-being of others, a diminished capacity for remorse, superficial charm, thrill seeking, and poor behavioral control. ASPD is not normally diagnosed in children or adolescents, but antisocial tendencies can sometimes be recognized in childhood or early adolescence. James Blair and his colleagues have studied the ability of children with antisocial tendencies to recognize facial expressions that depict sadness, happiness, anger, disgust, fear, and surprise. They have found that children with antisocial tendencies have selective impairments, with significantly more difficulty recognizing fearful and sad expressions. Suppose you have a sample of 40 16-year-old children with antisocial tendencies and you are particularly interested in the emotion of disgust. The average 16-year-old has a score on the emotion recognition scale of 11.80. (The higher the score on this scale, the more strongly an emotion has to be displayed to be correctly identified. Therefore, higher scores indicate greater difficulty recognizing the emotion). Assume that scores on the emotion recognition scale are normally distributed.
The null hypothesis is that your sample of children with antisocial tendencies would have no more difficulty recognizing emotion than the general population of 16-year-olds. Stated using symbols:_________. This is a __________ tailed test. Given what you know, you will evaluate this hypothesis using a________ statistic.
Answers
Step-by-step explanation
The answers in bold is what was required from the question.
the null hypothesis using symbol:-
H₀ : μ = 11.80
the alternative hypothesis using symbol:-
H₁: μ ≠ 11.80
This is a one tailed test. Given what you know, you will evaluate this hypothesis using a t test statistic.
Alpha level = 0.05
Sample size = n
Degree of freedom = n-1 = 40-1 = 39
To use the t distribution we will have to find the critical value from the t table this value is 1.685

%fat 34.6 42.5 28.8 33.4 30.2 34.1 32.9 41.2 35.7
Use R to answer the following questions. Include your R code with your submission, and plots (where applicable, you can take screenshots) and submit electronically.
(a) Calculate the mean, median and standard deviation of age and %fat.
(b) Draw the boxplots for age and %fat and interpret the results.
(c) Draw a scatter plot and interpret the results.
(d) Check the distribution of these two attributes.
(e) Calculate the correlation between these two attributes. Are these attributes positively or negatively correlated?
(f) Compute their covariance. Interpret the results.
Answers
We used R to analyze age and %fat data, including mean, median, correlation, boxplots, and scatter plot.
(a) To calculate the mean, median, and standard deviation of age and %fat, you can use the following R code:
# create age and %fat vectors
age <- c(23, 23, 27, 27, 39, 41, 47, 49, 50, 52, 54, 54, 56, 57, 58, 58, 60, 61)
fat <- c(9.5, 26.5, 7.8, 17.8, 31.4, 25.9, 27.4, 27.2, 31.2, 34.6, 42.5, 28.8, 33.4, 30.2, 34.1, 32.9, 41.2, 35.7)
# calculate mean
mean_age <- mean(age)
mean_fat <- mean(fat)
# calculate median
median_age <- median(age)
median_fat <- median(fat)
# calculate standard deviation
sd_age <- sd(age)
sd_fat <- sd(fat)
(b) To draw the boxplots for age and %fat, you can use the following R code:
# create boxplots
boxplot(age, main="Boxplot of Age")
boxplot(fat, main="Boxplot of Body Fat Percentage")
Interpretation: The boxplot for age shows that the median age is around 50, with the range of ages from 23 to 61. The boxplot for %fat shows that the median percentage of body fat is around 31%, with a range from around 8% to 42%.
(c) To draw a scatter plot, you can use the following R code:
# create scatter plot
plot(age, fat, xlab="Age", ylab="% Fat", main="Scatter plot of Age and Body Fat %")
Interpretation: The scatter plot shows that there is a positive correlation between age and %fat, with older adults generally having a higher percentage of body fat.
(d) To check the distribution of age and %fat, you can use the following R code:
# check distribution with histograms
hist(age, main="Histogram of Age", xlab="Age")
hist(fat, main="Histogram of Body Fat Percentage", xlab="% Fat")
(e) To calculate the correlation between age and %fat, you can use the following R code:
# calculate correlation
cor(age, fat)
(f) To compute the covariance between age and %fat, you can use the following R code:
# compute covariance
cov(age, fat)

What operation do you think Diego’s used to calculate the lengths for his drawing?
Answers
1. Diego subtract 10 to each length as follows:
15 - 10 = 5
36 - 10 = 26
30 - 10 = 20
18 - 10 = 8
12 - 10 = 2
21 - 10 = 11
In this way only the side which length is 5 is correct
2. Jada scales the drawing by the next scale factor:
5/15 = 1/3
where 5 is the desired length and 15 is the length of the original side.
Then, the other lengths are:
36*1/3 = 12
30*1/3 = 10
18*1/3 = 6
12*1/3 = 4
21*1/3 = 7
3. Diego's procedure is incorrect, as it is seen in his drawing. Subtraction is not the correct way to scale a drawing. On the other hand, Jada's procedure is correct.

The ticket sales at a movie theater were $4,740. Adult tickets are $15, and senior tickets are $10. The
number of senior tickets sold was 37 less than twice the number of adult tickets. Determine the
number of adult tickets and number of senior tickets sold.
How many adult tickets were sold?
How many senior tickets were sold?
Answers
Answer: 291 with a remainder of 375
Step-by-step explanation: What you need to do first is multiply the senior tickets by 37 which is 370. Now subtract 4,740 by 370 which equals 4370. Then divide 4370 by 15. 4370 divided by 15 equals 291. Multiply 291 by 15 (just to find the remainder) which equals 4,365. 4,740 subtracted by 4,365 equals 375. So the answer is 375

Answer:
SA = 1,176 ft².
Step-by-step explanation:
To find the surface area of the triangular prism, we can solve for the rectangular base, both triangular faces, and lateral sides separately.
For the rectangular base: (Use formula l×w)
20 × 18 = 360 ft²
For the triangular faces: (Use formula 1/2(b·h)
1/2(18 × 12) = 108 ft²
Since there are two faces, we need to double the amount.
108 × 2 = 216 ft².
Finally, solve for the lateral sides:
20 × 15 = 300 ft².
There are two sides, so:
300 × 2 = 600 ft².
Add up all of these areas:
600 + 216 + 360 = 1,176 ft²

What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 - 9 is an equation.
We have,
5x + 3y = 4p _____(1)
y = 2x + p ____(2)
Substituting (2) in (1) we get,
5x + 3(2x + p) = 4p
5x + 6x + 3p = 4p
11x = p
x = p/11
Now,
y = 2x + p
y = 2(p/11) + p
y = 2p/11 + p
y = 13p/11
Thus,
x is p/11
