Multiply 9 by 1/9.
19^1 so in other words, 19.
Answer:
Null Hypothesis, 
: P = 4.1%
Alternate Hypothesis, 
: P > 4.1%
Step-by-step explanation:
We are given that a psychologist claims that more than 4.1% of the population suffers from professional problems due to extreme shyness.
<u><em>Let p = true percentage of the population that suffers from extreme shyness.</em></u>
So, Null Hypothesis, : P = 4.1%
Alternate Hypothesis, : P > 4.1%
Here, <em><u>null hypothesis states that</u></em> % of the population who suffers from professional problems due to extreme shyness is equal to 4.1%.
On the other hand, <u><em>alternate hypothesis states that</em></u> more than 4.1% of the population suffers from professional problems due to extreme shyness.
So, the above hypothesis would be appropriate for conducting the test.
10/2 is equal to 5, so you would plot a point on 5
-9/2 is equal to -4.5 so you plot a point on -4.5
We know that
original volume of a cylinder=pi*r²*h
volume=1692.46 in³
1692.46=pi*r²*h
<span>if the radius becomes three times as large
so
r=3*r
new volume=pi*(3*r)</span>²*h----> 9*pi*r²*h
new volume=9*original volume
new volume=9*1692.46----> 15232.14 in³
the answer is
the new volume is 15232.14 in³
<h3><u>Answers in Step-By-Step</u></h3>
Step-by-step explanation:
A; the admission price is $15
For adults its 2x
For students its x
and for children under 3 years old its 1/2x
to find the weekend money replace "x" with 15 as the money.
Adults: 2 * 15
students: 15
infants: 1/2 * 15
Do the math
2 * 15 = 30
15 = 15
1/2 * 15 = 7.5
B; A group of 4 adults, 5 students, and 2 children under the age of 3 visits the theme park on Sunday.
for each adult is $30
each student is $15
and children under 3 is $7.50
Do the math
30 * 4 = 120
15 * 5 = 75
2 * 7.5 = 15
120 + 75 + 15 = $210
C; If a student's weekday cost's $18, find the total admission cost that group B) has to pay.
Adult: 18 * 2
Student: 18
infant: 1/2 * 18
do the math
18 * 2 = 36
18 = 18
1/2 * 18 = 9
each adult is $36
each Student is $18
each infant is $9
4 adults, 5 students, 2 children under 3
4 * 36 = 144
5 * 18 = 90
9 * 2 = 18
144 + 90 + 18 = 252
The total would come out to $252
