to be a parallelogram its front sides must be equal to each other

so, we equalize the length of two sides that are face to face

\begin{gathered} 5w-25=w+15 \\  \\  \end{gathered}

and solve for w

\begin{gathered} 5w-w=15+25 \\ 4w=40 \\ w=\frac{40}{4} \\  \\ w=10 \end{gathered}

the value of w must be 10

In a class, 60% of the students are girls. There are 18 girls in the class.
N76 [4]

Answer:

The answer is 30

Step-by-step explanation:

If you were to do 50% of 30, it would be 15 students that are girls. There's 18 students that are girls though, so the extra 10% would make 18 students in the class girls. The remaining 40% would be 12 boys. So basically you're taking 10% from one side and putting it in the other because 50% of 30 is 15 (well this is at least how I would do it, I don't know how others would do it though)

A 5-column table has 4 rows. The first column has entries A, B, C, Total. The second column is labeled X with entries 45, 20, 25
Setler [38]

Answer:

Step-by-step explanation:

To see if two events are independent you can use the formula P(a|b) = P(a)

In this problem P(C|Y) = 35/75 = .4667 and P(C) = 110/300 = 3.667,

therefore C and Y are not independent events because P(C∣Y) ≠ P(C).

The answer is choice D
