The average of 7 numbers is 60. The average of the first three numbers is 50, while the average of the last three is 70. What mu
Svetradugi [14.3K]

From the last two facts, we get

\dfrac{x_1+x_2+x_3}3=50\implies\dfrac{x_1+x_2+x_3}7=\dfrac{150}7

\dfrac{x_5+x_6+x_7}3=70\implies\dfrac{x_5+x_6+x_7}7=30

Then

\dfrac{x_1+x_2+\cdots+x_6+x_7}7=60\implies\dfrac{x_4}7=60-\dfrac{150}7-30\implies\boxed{x_4=60}

Solve angle X to 1 dp
geniusboy [140]

Answer:

x ≈ 57.8°

Step-by-step explanation:

using the Sine rule in the triangle

\frac{11}{sinx} = \frac{8}{sin38} ( cross- multiply )

8 × sinx = 11 × sin38° ( divide both sides by 8 )

sinx = \frac{11sin38}{8} , then

x = sin^{-1} ( \frac{11sin38}{8} ) ≈ 57.8° ( to 1 dec. place )
