Suppose ACT Reading scores are normally distributed with a mean of 21.3 and a standard deviation of 5.9. A university plans to a

Mekhanik [1.2K]

Answer:

30.0

Step-by-step explanation:

Given our data is normally distribute with $\mu=21.3$ and $\sigma=5.9$

-Top 7% is given by find the z-value corresponding to p=(1-0.07)=0.93

-We substitute our values in the equation below;

$z=\frac{\bar X-\mu}{\sigma}\\\\\\=\frac{X-21.3}{5.9}, z_{0.035}=1.476\\\\\therefore 1.476=\frac{X-21.3}{5.9}\\\\X=5.9\times 1.476+21.3\\\\=30.0084\approx30.0$

Hence, the minimum score required for the scholarship is 30.0

Answer:

1) $65\textdegree$

2) $44\textdegree$

3) $107\textdegree$

4) $82\textdegree$

Step-by-step explanation:

1) Since the whole angle is $180\textdegree$ , and to find the other angle, which is labeled as $x$ , you subtract $115\textdegree$ from $180\textdegree$ :

$180 - 115 = 65$

$x = 65\textdegree$

2) Since you already have two angle measures $46\textdegree$ and $90\textdegree$ , you add them up and subtract it from $180\textdegree$ to get the angle measure for $x$ :

$46 + 90 = 136$

$180 - 136 = 44$

$x = 44\textdegree$

3) Same thing from number 1. Subtract $73\textdegree$ from $180\textdegree$ :

$180 - 73 = 107$

$x = 107\textdegree$

4) Same thing from number 2. Add $52\textdegree$ and $46\textdegree$ and subtract it from $180\textdegree$ :

$52 + 46 = 98$

$180 - 98 = 82$

$x = 82\textdegree$
