Answer:
The two numbers are x = 8 and y = 5
Step-by-step explanation:
Let the two numbers be x and y
The difference of two numbers is 3 is represented as:
x - y = 3------------------Equation 1
Their sum is 13 is represented as:
x + y = 13----------------Equation 2
x - y = 3------------------Equation 1
Using method of Elimination by subtracting Equation 1 from Equation 2
x-x + y-(-y) = 13 - 3
2y = 10
y = 10/2
y = 5
Substituting y = 5 in Equation 2
x + 5 = 13
x = 13 - 5
x = 8
∴ The two numbers are x = 8 and y = 5
If two samples are selected from the same population, the two samples have exactly the same t statistics if the samples are same size and have the same variance and mean
The t-statistic is the ratio of the departure of the estimated value of a parameter from its hypothesized value to its standard error.
Variance is the expectation of the squared deviation of a random variable from its population mean or sample mean.
Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers
Hence, If two samples are selected from the same population, the two samples have exactly the same t statistics if the samples are same size and have the same variance and mean

Answer:
So you are given the function, f(x) = 3x - 4. You will plug in the value given and solve and write the answer down in the box.
f(x) = 3x - 4 ---> f(5), f(2), f(1), f(10), and f(-1) value given
f(5) = <u>3(5)</u> - 4
f(5) = <u>15 - 4</u>
f(5) = 11
f(2) = <u>3(2)</u> - 4
f(2) = <u>6 - 4</u>
f(2) = 2
f(1) = <u>3(1)</u> - 4
f(1) = <u>3 - 4</u>
f(1) = -1
f(10) = <u>3(10)</u> - 4
f(10) = <u>30 - 4</u>
f(10) = 26
f(-1) = <u>3(-1)</u> - 4
f(-1) = <u>-3 - 4</u>
f(-1) = -7

Answer:
2/3 I think, If not please tell me !
Answer:
smallest is 3L
biggest is 12L
Step-by-step explanation:
here is what i got, i hope it helps!
Pail=4 glasses
Jug=3 glasses
Glass=1 glass
4+3+1=8glasses
24L÷8glasses= 3L in each glass
pail=12L (4×3)
jug=9L (3x3)
glass=3L (1×3)
12L+9L+3L=24L
