Given sin x=13/85 and tan x=13/84 .

olga55 [171]

ANSWER:

We know that,

tanΘ = sinΘ/cosΘ

cosΘ = sinΘ/tanΘ

So, cosΘ = 13/85 ÷ 13/84

13/85 × 84/13
84/85.

A standardized test was given to a set of high school juniors and the distribution of the data is bell shaped. The mean score is

stira [4]

Answer:

920 points.

Step-by-step explanation:

We have been given that the mean score for a standardized test is 800 and the standard deviation is 120. To qualify for a special summer camp for accelerated students, a student must score within the top 16% of all scores on the test.

First of all we will find probability of 0.16 using normal distribution table.

Using normal distribution our Z score will be 0.994458

Now we will use raw-score formula to find the score (x) that a student must make to qualify for summer camp.

$x=\text{Mean}+\text{ Standard deviation* Z score}$

Upon substituting our given values in above formula we will get,

$x=800+120\times 0.994458$

$x=800+119.33496$

$x=919.33496$

Upon rounding to nearest whole number we will get,

$x=920$

Therefore, a student must make 920 points to qualify for summer camp.
