If z=14 and x=83 , then what is the value of y?

LenaWriter [7]

Answer:

y = 152

Step-by-step explanation:

The chord- chord angle x is half the sum of the arcs intercepted by the angle and its vertical angle, that is

$\frac{1}{2}$ (y + z) = 83 ( multiply both sides by 2 to clear the fraction )

y + z = 166

y + 14 = 166 ( subtract 14 from both sides )

y = 152

lord [1]

Answer:

The answer is "(27.030,29.770)"

Step-by-step explanation:

$(\bar{x}) = 28.4$

$(n)= 49$

$(\sigma) = 6$

$(CI) = \bar{x}\pm z^*_{\frac{\alpha}{2}} \frac{\sigma}{\sqrt{n}}$

$z^*_{\frac{\alpha}{2}}\ for \ 89\%\ confidence = 1.598 \\\\\text{Using z table }\\\\ NORM.S.INV(1-\frac{(1-0.89)}{2})$

$CI = 28.4 \pm 1.598 \times \frac{6}{\sqrt{49}}=(27.030,29.770)$
