Answer:
2.7>217/100
Step-by-step explanation:
The weights of eight puppies have the following statistics:
mean: 10
median: 7.5
mode: 7
List one set of possible weights in the table below.
Answer:
7, 7, 7, 7.5, 7.5, 14, 20, 10
Step-by-step explanation:
Since the median has to be 7.5, you know that the 4th and 5th numbers have to average out to 7.5. In simpler terms, the two numbers have to add up to 15 so that when you divide them by 2, you get 7.5. Then you know that the mode is 7. So, the magority of the numbers have to be 7. This is why I made the first 3 numbers 7. Then you know that the mean is 10, so all the numbers have to add up to 80. So, if you add up the numbers you have so far you get 36. This means that the remaning numbers have to add up to 44. Here you can really choose any numbers you want, as long as they add up to 44. That is why I chose, 14, 20, and 10. Lastly to check the numbers you put in, find the mean, median and mode. If they all match up with median: 7.5, mean: 10, and mode: 7, then your numbers work! Hope that helps!

One possible data set can be -
8, 7, 8, 7, 8, 7, 15, 7, 13
We have the following statistics for weights of eight puppies -
Mean: 10
Median: 7.5
Mode: 7
We have to list the set of possible weights for eight puppies.
Define Mean, Median and Mode for a given set of data.The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.
The median is the middle value when a data set is ordered from least to greatest.
The mode is the number that occurs most often in a data set.
According to the question, we have -
Number of puppies = 8
Mean = 10
Median = 7.5
Mode =7
Assume the sum of weights of all puppies be x. Therefore -
[tex]$\frac{x}{8} = 10[/tex]
x = 80
Now -
Mode = 7 → This means that the number 7 has occurred the most in the set.
Median = 7.5 → This means that 7 is the middle value when a data set is ordered from least to greatest. The data set can be -
8, 7, 8, 7, 8, 7, 15, 7, 13
Hence, one possible data set can be -
8, 7, 8, 7, 8, 7, 15, 7, 13

is 5:7. There are 36 students in the
class. How many more girls than boys
are there?
Answer:
tbh i may be too late but the answer is 6
Step-by-step explanation:
the ratio 5:7 in the question is basically saying for every 5 boys are 7 girls
if you multiply the number of boys by 5 ( which would equal 15) you would have 21 girls, 15 + 21 equals 36. 21- 15= 6 giving us the anser

You deposit $300 in a savings account. The account earns. 1% simple interest per year. What is the interest earned after 3 years? The balance after 3 years?
Please help, urgent
Answer:
9.09, 309.09
Step-by-step explanation:
Year1 300x.01=3. Balance is 303/(300+3)
Year2 303x.01=3.03 balance is 306.03
Year3 306.03x.01=3.06 balance=309.09
Answer:
Interest earned = $9
Balance after 3 years = $309
Step-by-step explanation:
For simple interest, the formula is I = PRT, where I is the interest earned or paid, P is the principal amount borrowed/deposited, R is the rate as a decimal, and T is the time in years.
I = PRT
I = (300)(0.01)(3)
I = 9
Add that to the amount deposited to start, and you have the balance aftere 3 years. $300 + 9 = $309

The length of a rectangular vegetable bed is 3 feet more than twice the width. The length of the fence around the bed is 36 feet. Find the length and width, and a specific equation to find it if the width is x.
Answer:
width = 5 feet
length = 13 feet
Step-by-step explanation:
length of a rectangular vegetable bed is 3 feet more than twice the width
l = 2x + 3
length of the fence around the bed is 36 feet
p = 2(l + x)
36 = 2(l + x)
18 = l + x
Substitute for l
18 = (2x + 3) + x
18 = 3x + 3
15 = 3x
x = 5
l = 2(5) + 3 = 13
Answer:
width= 5
length=13
equation (x is rectangle) = 18=(2x+3)+x

Mixing two kinds of candy the price of which was $2 and $4 per pound, Ella got a 10-lb mix of candy, which cost $2.90 per pound. How many pounds of each candy were used for the mix?
Answer:
4.5 pounds of candy y
5.5 pounds of candy x
Step-by-step explanation:
Given
Let x and y represent the two candies
[tex]x + y = 10[/tex] --- the sum of both candies
[tex]2x + 4y =29[/tex] ---- the worth of candies
Required
The pound of each
[tex]x + y = 10[/tex]
Make x the subject
[tex]x = 10 - y[/tex]
Substitute [tex]x = 10 - y[/tex] in [tex]2x + 4y =29[/tex]
[tex]2(10 - y) + 4y = 29[/tex]
Open bracket
[tex]20 - 2y + 4y = 29[/tex]
[tex]20 + 2y = 29[/tex]
Collect like terms
[tex]2y = 29 - 20[/tex]
[tex]2y = 9[/tex]
Solve for y
[tex]y = 9/2[/tex]
[tex]y = 4.5[/tex]
Recall that: [tex]x = 10 - y[/tex]
[tex]x = 10 - 4.5[/tex]

The proportion of adults who own a cell phone in a certain Canadian city is believed to be 65%. Forty adults are to be selected at random from the city. Let Xbe the number in the sample who own a cell phone. Under the assumptions given, the distribution of X is
A. Bin(40,0.65)
B. N(26,14)
C. Bin(40,26)
D. N(40,14)
Answer:
A. Bin(40,0.65)
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they have a cell phone, or they do not. The probability of an adult having a cell phone is independent of any other adult having a cell phone. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
In function of its parameters, the distribution is written as: Bin(n,p).
The proportion of adults who own a cell phone in a certain Canadian city is believed to be 65%
This means that [tex]p = 0.65[/tex]
Forty adults are to be selected at random from the city.
This means that [tex]n = 40[/tex].
Thus, we have Bin(40,0.65), and the correct answer is given by option A.

Round your answer to the nearest tenth of a cubic meter.
Answer:
7,329.60m³
Step-by-step explanation:
Volume of a cone = 1/3πr²h
r is the radius
h is the height
Given
r = 19.3m
h = 18.8m
Substitute
V = 1/3 * 3.14 * 19.3² * 18.8
V = 21,988.82968/3
V = 7,329.6 cubic meter

Police body cameras: A survey of New York State residents asked about police officers having to wear video cameras on duty. The question stated, "Do you agree or disagree that police officers should carry video cameras for the purposes of filming their activities while on duty?" Most (88%) respondents agreed with this statement. Do Californians share the same opinion? A California-based civil rights group conducted a similar survey by randomly selecting 500 California residents, and 425 agreed that police officers should carry video cameras for the purposes of filming their activities while on duty. Conduct a hypothesis test to determine if the proportion of California residents who agree is different from New York residents. Use a 5% significance level to make your decision. Use the applet (at the top of this Checkpoint) to determine the P-value. Which of the following is an appropriate conclusion based on the results?
a. The survey provides strong evidence that the proportion of California residents who agree that police officers should carry video cameras for the purposes of filming their activities while on duty is significantly different from the proportion of New York residents.
b. The survey suggests that the proportion of California residents who agree that police officers should carry video cameras for the purposes of filming their activities while on duty is 85%.
c. Of the California residents surveyed, 85% agree that police officers should carry video cameras for the purposes of filming their activities while on duty, but this is not strong enough evidence to conclude that the proportion of California residents who agree is significantly different from the proportion of New York residents.
d. This survey suggests that 88% of California residents surveyed agree that police officers should carry video cameras for the purposes of filming their activities while on duty.
