x/y + 3z^2 for x= 2/3, y= 6/7, and z=3
=2/3 / 6/7 + 3(3^2)
=2/3 * 7/6 + 3(9)
= 7/9 + 27
= 7/9 + 243/9
= 250/9
answer is a. 250/9
Answer:
x=11/9 hope this helped <3
Step-by-step explanation:
Let's solve your equation step-by-step.
34x+2x=44
Step 1: Simplify both sides of the equation.
34x+2x=44
(34x+2x)=44(Combine Like Terms)
36x=44
36x=44
Step 2: Divide both sides by 36.
Answer:
Second barn: 912 bricks
Third barn: 1826 bricks
Fourth barn: 1402 bricks
Step-by-step explanation:
(English question: The barn consists of 1259 bricks. The second barn has 347 bricks less. The third has 567 bricks more than the first barn and the fourth barn has 490 bricks more than the second barn. How many bricks consists of the second, third and fourth barn.)
If the second barn has 347 bricks less than the first barn, so the second barn has:
1259 - 347 = 912 bricks
The third barn has 567 bricks more than the first barn, so the third barn has:
1259 + 567 = 1826 bricks
The fourth barn has 490 bricks more than the second barn, so the fourth barn has:
912 + 490 = 1402 bricks
Answer:
1.66
Step-by-step explanation:
Calculation to find the standard deviation for the random variable X of the number of students who work full time in samples of size
Using this formula
Standard deviation(X)=√np(1−p)
Where,
n represent the number of students=16
p represent the percentage of all students who work full time=22
Let plug in the formula
Standard deviation(X)=√16(0.22)(1−0.22)
Standard deviation(X)=√(3.52)(0.78)
Standard deviation(X)=√2.7456
Standard deviation(X)=1.656
Standard deviation(X)=1.66 (Approximately)
Therefore the standard deviation for the number of students who work full time in samples of size 16 will be 1.66
