If 5% of a number equals 8, find 50% of that number.
Answer:
80 will be the answer.
Step-by-step explanation:
Let the number be x.
5% of x=8
(5/100)*x=8
x=(8*100)/5
x=160
Now,
50% of 160
=(50/100)*160
=80

One consequence of the popularity of the Internet is that it is thought to reduce television watching. Suppose that a random sample of 45 individuals who consider themselves to be avid Internet users results in a mean time of 1.98 hours watching television on a weekday. Determine the likelihood of obtaining a sample mean of 1.98 hours or less from a population whose mean is presumed to be 2.35 hours.
This question is incomplete, the complete question is;
One consequence of the popularity of the Internet is that it is thought to reduce television watching. Suppose that a random sample of 45 individuals who consider themselves to be avid Internet users results in a mean time of 1.98 hours watching television on a weekday. Determine the likelihood of obtaining a sample mean of 1.98 hours or less from a population whose mean is presumed to be 2.35 hours.
Assume that the standard deviation for "time spent watching television on a weekday" is 1.93 hours.
Answer:
the likelihood of obtaining a sample mean of 1.98 hours or less is 0.0985
Step-by-step explanation:
Given the data in the question;
x" = 1.98
μ = 2.35
s = 1.93
n = 45
so, p( x" < 1.98 ) = P( (x" - μ)/(s/√n) )
we substitute in our values,
p( x" < 1.98 ) = P( (1.98 - 2.35) / (1.93/√45) )
= p( -0.37 / 0.2877
= P( - 1.29 )
from standard normal table,
P( - 1.29 ) = 0.0985
Therefore, the likelihood of obtaining a sample mean of 1.98 hours or less is 0.0985

Charlie's business makes $1,051.75 on average each day. What should Charlie expect the business
to make in three weeks?
Answer:
$22,086.75 if he works 7 days a week! BUT in case of the scenerio where he works 5 days a week: $15776.25.
Step-by-step explanation:
Ok bro.
Depending on what kind of buisness he has here are the answers:
If he works 7 days a week, that means he works 21 days. 21 * $1,051.75 =
$22,086.75
If he works 5 days a week, that means he works 15 days. 15 * $1,051.75 =
$15776.25

Answer: Fourth Choice. -2
Step-by-step explanation:
Given
( -9 | 6 + ( -10 ) | ) / 2 · 3²
Expand (-10) parenthesis
= ( -9 | 6 - 10 | ) / 2 · 3²
Expand (-9|6-10|) parenthesis
= ( -9 | -4 | ) / 2 · 3²
= ( -36 ) / 2 · 3²
Simplify the denominator and get answer
= -36 / 2 · 9
= -36 / 18
= -2
Hope this helps!! :)

What is the area in square units of the figure shown below??help asap!don't share links or anything pleasee
Answer:
area equals 36 and 3 fourths because if you cut the triangle off of one of the sides and add it to the other side it makes a rectangle then you do length times width to find regular area of a rectangle.

Answer:
276yd^2
Step-by-step explanation:
14*12 + 9*12 = 168+108 = 276
Answer:
It’s 276 yd square
Step-by-step explanation:
you would have to split the shape into two different shapes.
9x12=108
12x14=168
then you would add both areas to get 276 which is the total area for this shape.

Find the area of this triangle.
Round to the nearest tenth.
7 in
133
13 in
[ ? ) in2
Answer:
33.3 in²
Step-by-step explanation:
Apply the formula for finding the area of triangle that has an included angle and two given sides, which is, Area = ½*a*b*Sin*C
Where,
a = 7 in
b = 13 in
C = 133°
Plug in the values
Area = ½*7*13*Sin(133)
Area = 33.2765935 ≈ 33.3 in² (nearest tenth)

2. Find the length of a side of a square if its area is:
a. 81 square inches
b. cm
c. 0.49 square units
d. m² square units
Answer:
9 inches ; 0.7 units ; m units
Step-by-step explanation:
The area of a square is give as :
The square of the side length of the square ; that is ;
Area of square = s² ;
Where s =! Side length of the square
Hence ;
A square with area = 81 in²
Length of its side = sqrt(81) = 9 inches
Area of square = 0.49 unit²
Length of its side = sqrt(0.49) = 0.7 units
Area of square = m² unit²
Length of its side = sqrt(m²) = m units
A factory produces bags of rubber bands. A bag of rubber bands has five different sizes: extra large (XL), large (L), medium (M), small (S), and extra small (XS). A quality control specialist collects a random sample of 450 rubber bands from the bagging machine and calculates a chi-square goodness-of-fit test to see if the frequencies for each size in the sample match the hypothesized distribution. The quality control specialist will test his sample against the following null hypothesis.H0:pXL=0.10,pL=0.20,pM=0.40,pS=0.20,pXS=0.10 How many medium rubber bands are expected in the random sample of 450 rubber bands?
Answer:
The expected frequency is 90
Step-by-step explanation:
If the given probabilities are taken as observed
pXL=0.10, 450*0.1= 45
pL=0.20, 450*0.2= 90
pM=0.40, 450*0.4= 180
pS=0.20, 450*0.2= 90
pXS=0.10 450*0.1= 45
We can assign the expected frequencies to be 450/5= 90 each
The chi square goodness fit test can be calculated as
Observed Expected (o-e) (o-e)² (o-e)² /e
45 90 -45 2025 22.5
90 90 0 0 0
