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.
0.21 is less than half because a half is 0.5.
So 0.21 is less than 0.5 because the tenths place is less than 5 which makes 0.21 smaller than a half
The value x in the equation h(x) = 4x-4 is, x =1
<h3>What is polynomial?</h3>
Polynomial functions are functions of a single independent variable.
To solve for x
Since h(x) =0
substitute h(x) into equation
h(x) = 4x - 4
0=4x - 4
Add 4 to both sides
4x = 4
Divide both side by 4
4x/4 = 4/4
x = 1
therefore, the value of X= 1

Here is you answer using matrixes
Answer:
20 kilograms of dough
Step-by-step explanation:
Given that;
12 kilograms working 6 hours
Rate = 12/6 kilogram per hour = 2 kilogram per hour
So,
In 10 hours he would produce;
Amount of dough = Time × rate
Time = 10 hours
= 10 hours × 2 kilograms per hour
= 20 kilograms of dough
