Answer:
(a) 93.19%
(b) 267.3
Step-by-step explanation:
The population mean and standard deviation are given as 502 and 116 respectively.
Consider, <em>X</em> be the random variable that shows the SAT critical reading score is normally distributed.
(a) The percent of the SAT verbal scores are less than 675 can be calculated as:
Thus, the required percentage is 93.19%
(b)
The number of SAT verbal scores that are expected to be greater than 575 can be calculated as:
So,
Out of 1000 randomly selected SAT verbal scores, 1000(0.2673) = 267.3 are expected to have greater than 575.
Answer:
<em>r</em>=2<em>p</em>
Step-by-step explanation:
If <em>r </em>is ruler and <em>p </em>is pen, ruler equals pen times 2, so its <em>r</em>=2<em>p</em>
<em>Solution</em><em>,</em>
<em>7</em><em>x</em><em>-</em><em>1</em><em>4</em><em>=</em><em>2</em><em>x</em><em>+</em><em>1</em><em>1</em>
<em>or,</em><em>7</em><em>x</em><em>-</em><em>2</em><em>x</em><em>=</em><em>1</em><em>1</em><em>+</em><em>1</em><em>4</em>
<em>or,</em><em>5</em><em>x</em><em>=</em><em>2</em><em>5</em>
<em>or,</em><em>X=</em><em>2</em><em>5</em><em>/</em><em>5</em>
<em>X=</em><em>5</em>
<em>The </em><em>answer</em><em> </em><em>is</em><em> </em><em>5</em><em>.</em>
