Answer:
(155.301 ; 159.299)
Step-by-step explanation:
Xbar = 157.3
Sample size, n = 234
Population standard deviation, σ = 15.6
The confidence interval :
Xbar ± standard Error
Standard Error = Zcritical * σ/√n
Zcritical at 95% = 1.96
Standard Error = 1.96 * (15.6/√234) = 1.999
Lower boundary : 157.3 - 1.999 = 155.301
Upper boundary : 157.3 + 1.999 = 159.299
(155.301 ; 159.299)

Ross has a plan to increase the number of sit-ups he does by the same percent each
week. The table shows his goal for each week of the plan.
Which expression gives the goal for the 52nd week?
Answer:
20•2^51
Step-by-step explanation:
The expression that gives the goal for the 52nd week is 20(2)⁵¹.
Week 1 2 3 4 5
Goals 20 40 80 160 320
This means the numbers are goals are increasing geometrically.
What is a geometric progression?A geometric progression is a series in which any element after the first is obtained by multiplying the preceding element by a constant called the common ratio.
We know the nth term of a GP = arⁿ⁻¹
Where a is the first term and r is the common ratio.
In our problem, a=20 and r=40/20=2
So, the 52nd term of the GP = 20(2)⁵²⁻¹
The 52nd term of the GP =20(2)⁵¹
Hence, the expression that gives the goal for the 52nd week is 20(2)⁵¹.

One hexagonal prism has dimensions that are triple the dimensions of a similar hexagonal prism. If the volume of the smaller prism is 4.75 cm3, what is the volume of the larger prism?
4.75 cm3
14.25 cm3
42.75 cm3
128.25 cm3
Answer:
128.25 cm³
Step-by-step explanation:
Volume of an hexagonal prism:
The volume of an hexagonal prism is given by:
[tex]V = \frac{3\sqrt{3} a^2h}{2}[/tex]
In which a and h are the dimensions.
Triple the dimensions
This means that the volume will be multiplied by 3^3, 27(as there are 3 terms which are dependent of the dimensions, a² and h).
If the volume of the smaller prism is 4.75 cm3, what is the volume of the larger prism?
27*4.75 = 128.25 cm³
128.25 cm³ is the answer

Andrew picks one marble at a time from a box and replaces it. He
repeats this process 25 times and records the results in the table. Based
on the table, which color marble has an experimental probability of 1/5?
4
Green
10
Answer:
Yellow.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes. Experimental probability is found taking into account previous experiments.
In this question:
6 + 5 + 4 + 10 = 25 total marbles.
The experimental probabilities are:
6/25 probability it is red.
5/25 = 1/5 probability it is yellow. Thus, the answer is yellow.
4/25 probability it is blue.
10/25 = 2/5 probability it is green.
The diameter of a circular mirror is 20 inches what is the area of the mirror? use 3.14?
Answer:
20/2 = 10
10 squared is 100 (10 x 10)
100 x (pi) = 314.159265359
But if we were to use 3.14 it would be 314
In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Joseph sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below. 103 visitors purchased no costume. 161 visitors purchased exactly one costume. 7 visitors purchased more than one costume. Based on these results, express the probability that the next person will purchase more than one costume as a decimal to the nearest hundredth.
The probability that the next person will purchase more than one costume is 0.03
How to solve for the probabilityWe have the following details to solve the problem with
The people that did not purchase any costume = 103
Those that purchased exactly one costume = 161
Those that purchased more than one costume = 7
The total number of persons that we have here would be
103 + 161 + 7
= 271
We are to find the probability that the next would purchase more than 1 costume.
This is given as:
7 / 271 = 0.0258
To the nearest hundredth = 0.03
Hence, 0.03 is the probability that the next person is going to buy more than one costume.

Answer:
81%
Step-by-step explanation:
27 no costume, 112 exactly one costume, 3 more than one costume.
27+112+3=142
There were a toal of 142 customers. 112+3=115 visitors purchased one or more costumes costumes.
Probability the next visitor will purchase one or more costumes:
115/142=0.809859
0.809859 times 100% = 80.9859%
which rounds to 81%
The probability as a percent to the nearest whole number is 81%
A number cube labeled 1 through 6 rolled three times. What is the probability that the first roll is a 1, the second roll is a 2, and the third roll is greater than 4?
Answer:
about 2/216 or 1/108
Step-by-step explanation:
the probability of it rolling 1 is 1/6. The probability of it rolling a 2 is 1/6. 1/6 times 1/6 is 1/36. the probability of it rolling a number greater than 4 is 2/6 since 5 and 6 are greater than 4. 1/36 times 2/6 is 2/216. Simplified is 1/108

Sharon is painting her house. she needs 5
gallons of brown paint for every 7 gallons of white paint. How many gallons of white paint does she need if she already bought 14 gallons of brown paint?
A. 10 gallons
B. 19.6 gallons
C. 16 gallons
D. 25 gallons
Answer:
19.6, B
Step-by-step explanation:
To solve, we need to figure out how many gallons of white paint she needs for every gallon of brown paint.
We are given this equation.
5 gallons of brown paint = 7 gallons of white paint
Divide both sides by 5.
1 gallon of brown paint = 7/5 gallons of white paint = 1.4 gallons of white paint
Now, using this, substitute 14 into the left side.
14 gallons of brown paint = 1.4 * 14 gallons of white paint
14 gallons of brown paint = 19.6 gallons of white paint
Thus, the answer is B, 19.6 gallons

A math teacher at George Washington Middle School asked boys in the 6th and 7th grades to report their shoe size. She used the results to create these histograms
Which conclusion best supported by the histograms?
A as boys get older, shoe sizes become more normally distributed with fewer large outliers.
B As boys get older, shoe size range, defined by the minimum and maximum, decreases
C As boys get older, shoe sizes increase and the distribution remains relatively unchanged.
D As boys get older, shoe size distribution becomes more spread with more large outliers
Answer:
As boys gets older, shoe sizes becomes more normally distributed with fewer large outliers.
Step-by-step explanation:
A visual analysi ls of the histogram distribution provided, we can observe that size distribution of 6 graders is positively skewed (right tailed) as outliers seems more to the right(large sizes). However, the second graph is balanced with a normal or symmetric distribution representing older age (7th graders). Hence, we can conclude that as the boys gets older, they attain normality in terms of their shoe sizes. And the outliers which are characterized by the first histogram having vanished or reduced.
