Answer: 0.0895
Step-by-step explanation:
Let p= population proportion.
Given : Sample size : n= 500
p= 0.47
Required probability = [tex]P(\ha{p}>0.50)[/tex]
[tex]=P(\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}>\dfrac{0.50-0.47}{\sqrt{\dfrac{0.47(1-0.47)}{500}}}) \\\\=P(z>1.344)\ \ \ [z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}]\\\\=1-P(z<1.344)\\\\=1-0.9105\approx0.0895[/tex]
Hence, required probability = 0.0895
Joshua is planning to make a large consumer purchase. If the item costs x dollars in his home state of West Virginia, where the tax rate is 6%, the function f(x) = 0.06x + x represents his total costs. Write a function g(x) to represent Joshua’s total costs if he decides to make the purchase in his neighboring state of Virginia, where the tax rate is 5%. How will the graph of g(x) differ from f(x)?
Answer:
g(x)=.05x+x
The graphs will be very similar but f(x) first one should increase a little faster

Answer:
Last year there were 550 bison in the heard and this year it is 10% larger.
10% is also 10/100 or 0.10
To find 10% of the heard last year
550 x.0.10 = 55. To find the number in the heard this year add 550 (last year) + 55 (10% growth) = 605 or,
to find how many there are now last years heard size was 100% of the heard or 1.00. To find any percent more add it to 1.00 and multiply by the starting amount.
550 x 1.10 = 605
For the second example.
If there are 550 bison in the heard this year, and this year was a decrease of 10% from last year we can express last year's number like this.
550 = (x - (x * 0.10)) simplify;
550 = 1x - 0.10x
550 = 0.90x
Divide both sides by 0.90
x = 611.11 but it's hard to have 0.11 of a bison so realistically 611 bison last year. Subtract 10% or 61 and you indeed have 550 this year.

Of 10 students surveyed in school,7 picked summer as their favorite season.If the school has 350 students,how many can be expected to prefer summer
Answer:
245
Step-by-step explanation:
This is a ratio
7/10 = 70% = the kids who picked summer which leaves off as 30% for an unknown season
7 : 10
245 : 350
The 7 is how many students chose summer, and the 10 is the number of students there are in general
The 245 is the number of students who chose summer, and the 350 is the number of students there are in general
All we had to do was see how many times 10 goes into 350, which is 35 times. So we multiply 10 by 35 and we get 350. Now whatever we do on one side, we need to do it to the other. So 7 times 35 gives us 245. And that's how I know that out of the 350 students there are in total, 245 of them chose summer.
Hope this helped!

Step-by-step explanation:
2log(x)=log(64)
By logarithms properties

log(x²)=log(64)
When you have log or ln in both sites, you delete them and...
x²=64

The dimensions of a rectangular swimming pool can be represented as (3x - 8) feet and (8x + 7) feet.
Select one answer that represents the area of the swimming pool
Answer:
Area of pool = 24x²-43x-56 square feet
Step-by-step explanation:
Given that:
Dimensions of rectangular swimming pool = 3x - 8 and 8x + 7
Area of the swimming pool can be calculated by multiplying the dimensions.
Area of pool = (3x-8)(8x+7)
Area of pool = 3x(8x+7)-8(8x+7)
Area of pool = 24x²+21x-64x-56
Area of pool = 24x²-43x-56
Hence,
Area of pool = 24x²-43x-56 square feet
The plans or an apartment complex were laid out on the first quadrant of a coordinate plane. The complex will have two postal delivery centers. One center is located at (1, 5), and the other is located at (10, 17). If each grid unit equals 100 yards, how far apart are the postal delivery centers?
Answer:
1500yards
Step-by-step explanation:
Distance between two coordinates is expressed as;
D = √(x2-x1)²+(y2-y1)²
Given the coordinates (1,5) and (10, 17)
D = √(10-1)²+(17-5)²
D = √(9)²+(12)²
D = √81+144
D= √225
D = 15 units
Since 1 unit = 100yards
15 units = x
x = 15(100)
x = 1500 yards
Hence the delivery centres are 1500yards apart

What is probability?"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."
The formula of the probability of an event A is:P(A) = n(A) / n(S)
where, n(A) is the number of favorable outcomes and n(S) is the total number of events in the sample space.
For given question,
Number on dice = 1, 3, 3, 4, 4
⇒ S = {1, 3, 3, 4, 4}
total outcomes n(S) = 5
Let event A: getting 1 on dice
⇒ n(1) = 1
Using the formula of probability,
P(A) = n(A) / n(S)
⇒ P(A) = 1/5
⇒ P(A) = 0.2

A movie theater charges 10.50 per person for admission. In one hour, the theater raised $19.11 in admission fees. Write and solve an equation to find how many people visted in a hour.
Answer:
a. C = $ 10.50x b. 2 persons
Step-by-step explanation:
a. Write an equation to find how many people visited in a hour
Let x be the number of persons admitted in one hour. Since the movie theater charges 10.50 per person for admission, then the total admission fees would be C = charge per person × number of persons = $ 10.50 × x = $ 10.50x.
C = $ 10.50x
b. Solve an equation to find how many people visited in a hour
Given that C = $19.11, and C = $ 10.50x, so,
x = C/($10.50)
substituting C into the equation, we have
x = $19.11/$10.50
x = 1.82
Since we cannot have a decimal number of persons, x is rounded up to the nearest whole number. So,
x = 1.82
x ≅ 2
So, two people visited the theater in one hour.

A shoe store has a markup rate of % and is selling a pair of shoes for $. Find the price the store paid for the shoes.
Answer: $76
Step-by-step explanation:
Stores buy goods from others and sell it at a higher price to make profit. The difference between the price they bought it for and the one they will sell is the markup.
The markup percentage represents that markup in terms of the original cost.
If the price now is 75% higher than the original price, assume the original price to be x.
Expression is:
x + (x * 75%) = 133
x + 0.75x = 133
1.75x = 133
x = 133/1.75
x = $76
