Answer:
$6.25
Step-by-step explanation:
Each football costs the same amount, and each basketball costs the same amount.
Let the cost of:
Footballs = f
Basketballs = b
Hence, we have the following system of equations
At the first store, the coach paid $110 for 5 footballs and 14 basketballs.
5f + 14b = 110
At the second store, the coach paid $82.50 for 10 footballs and 6 basketballs.
10f + 6b = 82.50
What was the cost in dollars of each basketball?
5f + 14b = 110..... Equation 1
10f + 6b = 82.50.....Equation 2
We solve using Elimination method.
Multiply Equation 1 by 10 and Equation 2 by 5 to eliminate f
50f + 140b = 1100.... Equation 3
50f +30b = 412.5.......Equation 4
Subtract Equation 4 from Equation 3
110b = 687.5
b= 687.5/110
b = $6.25
Therefore, the cost of one basketball in dollars = $6.25
Multiply and simplify
3√50 x √22

if each value of the data of the poplation function is doubled which of the following is not correct?
A. the mean is doubled
B. the mode is doubled
C. the variance is doubled
D. the median is doubled
Answer:
The variance is doubled; C
Step-by-step explanation:
Here, we want to select what will be wrong if every number in the dataset is doubled
A. This is correct
The mean is the average of the numbers which is calculated by dividing the sum of the numbers by the count of the numbers
By doubling the numbers, we have simply doubled the sum while the count is same
So what we have as the result of the division will be 2 times what we had initially making the mean doubled
B. The mode is doubled
Yes, this is correct
The mode is the highest in frequency
Doubling all numbers will not double their frequencies but their values. So the number that was the mode in the previous case will be the same but now doubled
D. The median is doubled
This is correct
The median deals with the middle number.
Since all numbers are doubled in the present case, the median to is also doubled along side as the numbers are now twice what they were evenly
C. This is wrong
The variance has to do with the spread of data
We are actually subtracting values
Since we are doubling across board, the difference between the numbers is the same as this, the variance cannot change
We can look at this from the angle that all others are measures of central tendency looking at having a central figure while the variance is a measure of spread.

PLSSS HELP ANSWER, THE QUESTION IS IN THE SCREENSHOT
Since the room temperature is 22 degrees Celsius,
[tex]\frac{dT}{dt}=k(T-22)[/tex]
Solving the differential equation,
[tex]\frac{1}{T-22} dT=k dt \\ \\ \int \frac{1}{T-22} dT=\int k dt \\ \\ \ln|T-22|=kt+C[/tex]
When t=0, the temperature is 100 degrees.
[tex]\ln 78=C \\ \\ \implies \ln|T-22|=kt+\ln 78[/tex]
When t=1, the temperature is 80 degrees.
[tex]\ln 58=k+\ln 78 \implies k=\ln(29/39) \\ \\ \implies \ln|T-22|=t \ln(29/39)+\ln 78[/tex]
Setting t=4,
[tex]\ln|T-22|=4\ln(29/39)+\ln 78 \\ \\ T=22+e^{4\ln(29/39)+\ln 78} \approx \boxed{46}[/tex]
add to both sides: add what to both sides 8+1/9x+ =-4+
Answer:
Step-by-step explanation:
Now add - x to both sides by the addition rule. Remember, adding the same quantity to both sides of an inequality does not change its direction.

Select all that apply. There are 11 boys and 15 girls in a class. Which of the following show the ratio of girls to boys? 15.15
Answer:
15:11
Step-by-step explanation:
well, girls to boys would be 15 to 11 because there are 15 girls and 11 boys. it cant be simplified further, so its 15:11
edit: I've noticed that it sounds like I'm saying girls is first because there are more, but it's because the question asks for girls to boys, not because there are more girls
Answer:
11:15
Step-by-step explanation:
Finding a ratio is very simple, all you have to do is take the first number, put a :, and then put the second number.
The : can also be replaced with a . or / so the answer to this question might also be seen as:
11/15
11.15
