X-Zs/\sqrt{x} \\X+Zs/\sqrt{x}

Where X is the mean and s is the standard deviation and x the sample size:

99-1.96\cdot{5}/\sqrt{22} \\99+1.96\cdot{5}/\sqrt{22}

The interval is (96.91, 101.09)

Answer:

<BCA = 44.4°

Step-by-step explanation:

Reference angle = <BCA = C

Opposite side length = x = 7 cm

Hypotenuse = y = 10 cm

Applying trigonometric ratio, we would have:

sin(C) = \frac{7}{10}

C = sin^{-1}(\frac{7}{10})

C = 44.427004

<BCA = 44.4° (to 3 SF)
