Answer:
5.5 ft
Step-by-step explanation:
because its 4ft for every 1ft there's a ratio of 1:4 so 22 represents the 4 part of the ratio, hence 22 divided by 4 gives us 5.5 on the base
Answer:
y = (1/3)x + 4
Step-by-step explanation:
Two points on this line are (0, 4) and (3, 5).
As we move from the first point to the second, x increases by 3 and y increases by 1. Thus, the slope, m, of the line is m = rise / run = 1/3.
Use the slope-intercept equation: y = mx + b.
If we use the data from the point (0, 4), we get:
4 = (1/3)(0) + b, so that b = 4. The desired equation is y = (1/3)x + 4.

Answer:
a
b
Step-by-step explanation:
From the question we are told that
The mean value is 
The standard deviation is 
Considering question a
The sample size is n = 9
Generally the standard error of the mean is mathematically represented as
=> 
=> 
Generally the probability that the sample mean hardness for a random sample of 9 pins is at least 51 is mathematically represented as
=> 
From the z table the area under the normal curve to the left corresponding to 2.5 is
=> 
=>
Considering question b
The sample size is n = 40
Generally the standard error of the mean is mathematically represented as
=> 
=> 
Generally the (approximate) probability that the sample mean hardness for a random sample of 40 pins is at least 51 is mathematically represented as
=> 
=> 
From the z table the area under the normal curve to the left corresponding to 5.2715 and
=> 
So
=>
Answer:
$1.15
Step-by-step explanation:
add the cost of all of the items: 1 + 3.50 + 3.50 + 1 = 9
multiply 9 by the given discount: 9 x 0.15 = 1.35
you get 1.15, this is the dollar price of the discount
