Answer:
7
Step-by-step explanation:
first you get the area of the square which is 4 then you get the area of the triangle which would be 3 because 2x3=6 then divide by 2 because its a triangle and add the areas of both and its 7

Hi, could anyone help please ? I can't manage to get this right...
So everything you have now is right so far:
[tex]\cos(24) = \frac{z}{118}[/tex]
Multiply 118 to the left side to isolate z
[tex]118\cdot\cos(24) = z[/tex]
z = 50.05
Hope this helps
Recently many companies have been experimenting with telecommuting, allowing employees to work at home on their computers. Among other things, telecommuting is supposed to reduce the number of sick days taken. Suppose that at one firm, it is known that over the past few years employees have taken a mean of 5.4 sick days. This year, the firm introduces telecommuting. Management chooses a simple random sample of 80 employees to follow in detail, and at the end of the year, these employees average 4.5 sick days with a standard deviation of 2.7 days.
a) Describe the population in the context of this problem
b) Describe the parameter u in the context of this problem.
c) Describe the sample in the context of this problem.
d) Describe the statistic in the context of this problem
e) The firm would like to know if there is evidence that the true mean number of sick days for all employees of the firm has decreased after telecommuting was introduced. State the hypotheses. Use ?-0.10.
f) Check the assumptions. If you don't know if an assumption is satisfied based on the information provided, then state "We must assume
g) Calculate the test statistic
h) Find the p-value.
i) Make a decision.
j) State the conclusion in terms of the problem.
Answer:
A.) Population : All employees at a firm
B.) μ = 5.4
C.) Sample : 80 employees at a firm
D.) Sample mean, x bar = 4.5
Step-by-step explanation:
From the question :
E.)
H0: μ ≥ 5.4
H1 : μ < 5.4
F.)
If Pvalue < α ; Reject H0
G.)
Test statistic :
(xbar - μ) ÷ (s/sqrt(n))
(4.5 - 5.4) ÷ (2.7/sqrt(80))
-0.9 ÷ 0.3018691
= - 2.98
H.)
Pvalue fro Zscore calculator, α = 0.10 = 0.002882
I.)
Decision :
0.002882 < 0.10
Since, Pvalue < α ; We reject the Null
J.)
We Can conclude that the true mean number of sick days for all employees of the firm has decreased after telecommuting was introduced

if f(x) and g(x) are inverse function, find f(g(x)).
Answer:
The answer is x.
Step-by-step explanation:
Inverse functions undo each other, so if f(x) spits out a number, g(x) reverses that and gives you x again.

During a 20 kilometer hike, Deana consumed 3 3/4 quarts of water.
What was Deana's average water consumption in quarts per kilometer?
Answer:
16.7
Step-by-step explanation:
The amount of water consumed is 334 quarts
The distance is 20km
Therefore the average water consumption can be calculated as follows
= 334/20
= 16.7
Hence the consumption rate is 16.7 quarts/km
Explain why the denominator 8 in 8/4 is not changed when adding the fractions.

"Solve the following system of equations."
-5x+3y=22
-6x+7y=23
I have to figure out x and y
Answer:
x = - 5, y = - 1
Step-by-step explanation:
Given the 2 equations
- 5x + 3y = 22 → (1)
- 6x + 7y = 23 → (2)
Multiplying (1) by - 6 and (2) by 5 , then adding will eliminate the x- term
30x - 18y = - 132 → (3)
- 30x + 35y = 115 → (4)
Add (3) and (4) term by term to eliminate x
0 + 17y = - 17
17y = - 17 ( divide both sides by 17 )
y = - 1
Substitute y = - 1 into either of the 2 equations and solve for x
Substituting into (1)
- 5x + 3(- 1) = 22
- 5x - 3 = 22 ( add 3 to both sides )
- 5x = 25 ( divide both sides by - 5 )
x = - 5

xy=80 solve log x- log y=1
Question: Solve for x and y in the equation.
xy=80 and log x - 2 log y =1
Answer:
x = 40, y = 2
Step-by-step explanation:
xy = 80.......................... Equation 1
logx-2logy = 1
logx-logy² = 1
Applying the laws of logarithm,
log(x/y²) = log10
x/y² = 10
x = 10y²......................... Equation 2
Substitute the value of x in therms of y equation 2 into equation 1
10y²(y) = 80
10y³ = 80
y³ = 8
y = [tex]\sqrt[3]{8}[/tex]
y = 2.
Substitute the value of y into equation 1
2x = 80
x = 80/2
x = 40
Therefore,
x = 40, y = 2

Justine signed up for a gym membership. The gym charges a one-time fee of $59 plus a monthly fee. Justine determines that she will pay a total of $557 for her gym membership after one year. How much does the gym charge per month?
The gym charges $41.5 per month.
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now it is given that,
One time fee of gym = $59
Justine will pay after one year = $557
So, gym fees per year = $557 - $59
⇒ gym fees per year = $498
∴ gym fees per month = gym fees per year / 12
⇒ gym fees per month = $498/12
⇒ gym fees per month = $41.50
Thus,the gym charges $41.50 per month.

Answer:
C, y =8x
Step-by-step explanation:
As you can see from the table, y is basically x multiplied by 8 at all instances.
Answer: y=8x
Step-by-step explanation:
y=8x means that the number in the y column (the total cost) equals whatever is in the x column (number of tickets) times by 8. The reason you do times is because in algebra when a number is next to a letter it means times.
So, you can test it using the data in the table:
16=2×8
24=3×8
32=4×8 etc.
And we know it works.
