Stanley is building a rectangular fence 44feet of fencing. If the width is two less than half the length, what is the width of the fence? Write an equation and solve.
Answer:
The width of the fence measures 6 feet
Step-by-step explanation:
Firstly, we assign variables.
Let the width of the fence be represented by w and the length by l
Now let’s get what the length would be. width is 2 less than half length
w = l/2 - 2
or simply l/2 = w + 2
which is same as l = 2(w + 2)
Now the perimeter of the fencing is 44. The perimeter of a rectangle can be calculated using the formula
P = 2(l + w)
Now let’s insert what we have:
P = 44 and l = 2(w + 2)
44 = 2(2(w+2) + w)
44 = 2(2w + 4 + w)
44 = 2(3w + 4)
44 = 6w + 8
6w = 44-8
6w = 36
w = 36/6
w = 6 feet

1.3.7Rock-paper-scissorsHave you ever played rock-paper-scissors (or Rochambeau)? It’s considered a "fair game" in that the two players are equally likely to win (like a coin toss). Both players simultaneously display one of three hand gestures (rock, paper, or scissors), and the objective is to display a gesture that defeats that of your opponent. The main gist is that rocks break scissors, scissors cut paper, and paper covers rock, which explored players’ choices in the game rock-paper-scissors.Suppose that you play the game with three different friends separately with the following results: Friend A chose scissors 100 times out of 400 games, Friend B chose scissors 20 times out of 120 games, and Friend C chose scissors 65 times out of 300 games. Suppose that for each friend you want to test whether the long-run proportion that the friend will pick scissors is less than 1/3.
Complete Question
The complete question is shown on the first uploaded image
Answer:
The correct option is C
Step-by-step explanation:
From the question we are told that
The number of outcome is 3 (rock paper and scissors)
The number of game you and the first friend played is a = 400
The number of times friend A chose scissors is b = 100
The number of game you and the second friend played is c= 120
The number of times friend B chose scissors is d = 20
The number of game you and the third friend played is e = 300
The number of times friend B chose scissors is f = 65
Generally the probability of success of each outcome is
[tex]p = \frac{1}{3} = 0.33[/tex]
Generally the probability of failure of each outcome is
[tex]q = 1-p[/tex]
=> [tex]q = 1-\frac{1}{3}[/tex]
=> [tex]q = \frac{2}{3} = 0.67[/tex]
Generally the proportion of scissors chosen by friend A is mathematically represented as
[tex]p_1 = \frac{b}{a}[/tex]
=> [tex]p_1 = \frac{100}{400}[/tex]
=> [tex]p_1 = 0.25[/tex]
Generally the proportion of scissors chosen by friend B is mathematically represented as
[tex]p_2 = \frac{d}{c}[/tex]
=> [tex]p_2 = \frac{20}{120}[/tex]
=> [tex]p_2 = 0.167[/tex]
Generally the proportion of scissors chosen by friend B is mathematically represented as
[tex]p_3 = \frac{f}{e}[/tex]
=> [tex]p_3 = \frac{65}{300}[/tex]
=> [tex]p_3 = 0.2167[/tex]
Generally the standardized value for friend A is mathematically represented as
[tex]z_1 = \frac{p_1 - p}{\sqrt{\frac{p* q}{a} } }[/tex]
=> [tex]z_1 = \frac{0.25- 0.33}{\sqrt{\frac{0.33* 0.67}{400} } }[/tex]
=> [tex]z_1 = -3.4[/tex]
Generally the standardized value for friend B is mathematically represented as
[tex]z_2 = \frac{p_2 - p}{\sqrt{\frac{p* q}{c} } }[/tex]
=> [tex]z_2 = \frac{0.167- 0.33}{\sqrt{\frac{0.33* 0.67}{120} } }[/tex]
=> [tex]z_2 = -3.8 [/tex]
Generally the standardized value for friend C is mathematically represented as
[tex]z_3 = \frac{p_3 - p}{\sqrt{\frac{p* q}{e} } }[/tex]
=> [tex]z_3 = \frac{0.2167- 0.33}{\sqrt{\frac{0.33* 0.67}{300} } }[/tex]
=> [tex]z_3 = -4.17 [/tex]
Answer: C
reason: There are special rules to follow when an expression is raised to the power of 0 or 1. Remember these rules when using numerical expressions involving the exponents 0 and 1:
Any number raised to the power 0 is equal to 1. For example, 120 is equal to 1 and 300 is equal to 1. However, this rule does not apply when 0 is the base: 0 raised to any power other than 0 is equal to 0, and 00 is not defined.
Any number raised to the power 1 is equal to the number itself. For example, 121 is equal to 12, 301 is equal to 30, and 01 is equal to 0
A numerical expression contains numbers and operations but not the equality symbol (=). Here are some examples of numerical expressions:
15 + 4 − 2
56 ÷ 7 + 5 × 5 × 5
32 × 5 + 7
Numerical expressions can also be written in words, such as "nine times six minus seven" and "five divided by ten plus two."
Look at the expression 56 ÷ 7 + 5 × 5 × 5. Instead of writing 5 three times in the expression, we can replace it with a whole-number exponent. For that, we write 5 × 5 × 5 as 53:
56 ÷ 7 + 5 × 5 × 5
56 ÷ 7 + 53.
Let's write 2 × 3 × 3 × 3 × 3 × 3 × 3 with a whole-number exponent. Here, 3 is multiplied by itself and occurs 6 times in the expression. Instead of writing 3 six times, we can write 3 × 3 × 3 × 3 × 3 × 3 as 36. So, 2 × 3 × 3 × 3 × 3 × 3 × 3 is the same as 2 × 36.

The US Census reported that it takes workers an average of 28 minutes to get home from work with standard deviation 5 minutes. A random sample of 10 workers in a large metropolitan area showed an average time to get home from work to be 32 minutes. Is this evidence that workers in the large city take longer than 28 minutes to get home from work.
Using the z-distribution, as we have the standard deviation for the population, to test the hypothesis, it is found that this is evidence that workers in the large city take longer than 28 minutes to get home from work.
What are the hypothesis tested?At the null hypothesis, it is tested if the mean time is of 28 minutes, that is:
[tex]H_0: \mu = 28[/tex]
At the alternative hypothesis, it is tested if the mean time is greater than 28 minutes, that is:
[tex]H_1: \mu > 28[/tex].
What is the test statistic?The test statistic is given by:
[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
The parameters are:
[tex]\overline{x}[/tex] is the sample mean.[tex]\mu[/tex] is the value tested at the null hypothesis.[tex]\sigma[/tex] is the standard deviation of the sample.n is the sample size.In this problem, the values of the parameters are given by:
[tex]\overline{x} = 32, \mu = 28, \sigma = 5, n = 10[/tex]
Hence:
[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{32 - 28}{\frac{5}{\sqrt{10}}}[/tex]
[tex]z = 2.53[/tex]
What is the decision?Considering that we have a right-tailed test, as we are testing if the mean is greater than a value, with a standard significance level of 0.05, the critical value is of [tex]z^\ast = 1.645[/tex].
Since the test statistic is greater than the critical value, it is found that this is evidence that workers in the large city take longer than 28 minutes to get home from work.

Solve for x:
3*4+-9-x=10
Answer:
-7
Step-by-step explanation:
first multiply 3 and 4 because PEMDAS
so it now looks like
12 - 9 - x = 10
now minus 12 and 9
3 - x = 10
move x to the other side by adding x to both sides
3 = 10 + x
and move 10 to the other side by subtracting 10 to both sides
3 - 10 = x
x = -7
now check

A salt mixture has 8 parts water and 2 parts salt. Suppose one part of each is added. What is the new ratio of salt to
water?
A. 2 to 9
B. 3 to 8
C. 3 to 9
D. 9 to 3
Answer: C. 3 to 9
You simply add 1 to each given value (8 and 2)
The ratio 9 to 3 represents the ratio of water to salt, so 3 to 9 is the ratio of salt to water.
Edit: Realized I had the parts mixed up, but the solution has been fixed
Rule In Out 89 88 77 61 50 39 22

The Product Rule: If there are n(A) ways to do A and n(B) ways to do B, then the number of ways to do A and B is n(A) × n(B). This is true if the number of ways of doing A and B are independent; the number of choices for doing B is the same regardless of which choice you made for A.
Suppose f is a linear function such that f(4) = 8 and f(7) = 3. Find the equation for f
Answer:
f(x) = -5/3 x +44/3
Step-by-step explanation:
helo : let f(x)= ax+b
f(4) = 8 means : a(4)+b=8 and f(7) = 3 means : a(7)+b=3
you have this system : 4a +b = 8....(*)
7a+b = 3 ....(**)
solve this system use (*) : b = 8 -4a and use (**) : b = 3-7a
so : 8-4a = 3-7a
-4a+7a = 3-8
3a = -5 so a = -5/3
but b =8-4a so : b= 8-4(-5/3) =8+20/3 =44/3
f(x) = -5/3 x +44/3

This means [tex](9,1) \to (-1,9)[/tex] meaning (9,1) rotates to (-1,9)
Notice that (9,1) on figure S corresponds to (-1,4) on figure T.
This means after arriving to (-1,9), we need to somehow apply a shifting translation to get to (-1,4)
To get from (-1,9) to (-1,4) we shift the point down 5 units.
-----------------------
To recap:
We rotated (9,1) around the origin 90 degrees counterclockwise to get to (-1,9)Then we shifted (-1,9) down 5 units to get to (-1,4)If you apply that rotation and shifting rule to each of the four corner points of figure S, then you'll end up with figure T.
Figure S is known as the preimage while figure T is the image.
X degree + X degree + (2x+3)degree + (2x+3) degree= 360 degrees
Answer:
Step-by-step explanation:
x + x + 2x + 3 + 2x + 3 = 360
6x + 6 = 360
Divide by 6
x + 1 = 60
x = 60 - 1 = 59
18. A cell phone manufacturer found that,

An airliner carries 200 passengers and has doors with a height of 72in. Height of men is normally distributed with a mean of 69 in, and a standard deviation of 2.8 in. and half of 200 passengers are men. Find z score of the sample means. Find the probability that mean height of 100 men is less than 72 in.
Answer:
Step-by-step explanation:
a) 0.6406; b) 1.000; c) C. The probability from part (a) is more relevant because it shows the proportion of male passengers that will not need to bend; d) B. Since men are generally taller than women, a design that accommodates a suitable proportion of men will necessarily accommodate a greater proportion of women.
