Answer:
-1/4
Step-by-step explanation:
The slope-intercept form is y
=
m
x+b
,
where m is the slope and b is the y-intercept.
y
=
m
x
+
b
Using the slope-intercept form, the slope is 4.
4 m

The equation of a perpendicular line to
y
=

It would also be 18 degrees
The intensity of a fire alarm that measures 125 dB loud is 268,337.29
<h3>Formula and expressions</h3>
Given the expression L=10 logI
where;
- L is the loudness
- I is the intensity of the sound.
Given the following parameters
L = 125dB
Substitute the given parameters into the following
L=10 logI
125 = 10logI
logI = 125/10
logI = 12.5
I = e^12.5
I = 268,337.29
Hence the intensity of a fire alarm that measures 125 dB loud is 268,337.29

Answer:
(0.5793, 0.6363)
Step-by-step explanation:
Given that a poll of 793 adults aged 18 or older asked about purchases that they intended to make for the upcoming holiday season. One of the questions asked about what kind of gift they intended to buy for the person on whom they would spend the most. Clothing was the first choice of 482 people.
i.e. sample proportion p= 

Std error of p = 
For 90% Z crtiical = 1.645
Hence margin of error = 1.645 * std error = 0.0285
Confidence interval 90%
= proportion ±margin of error
=
-6a-48 that would be it because you are only distributing the -6
