Answer:
The answer is <ACD = 68°
Step-by-step explanation:
Using the property that the sum of interior angles in a triangle is equal 180°,we have:
<DAC + <ACD + <ADC = 180°
[tex]2x + (180 - 4x) + 56 = 180 \\ - 2x + 56 = 0 \\ 2x = 56 \\ x = \frac{56}{2 } \\ x = 28[/tex]
Finally, calculating the angle <ACD, we have:
<ACD = 180 - 4x
<ACD = 180 - 4 . 28
<ACD = 180 - 112
ACD = 68°
Answer:
x = 28°
m∠ACD = 68°
Step-by-step explanation:
From inspection of the given diagram:
m∠FDC = 124°m∠EAB = 2xm∠ACG = 4xVertical Angle Theorem
When two straight lines intersect, the vertical angles are congruent.
⇒ m∠DAC = m∠EAB = 2x
Angles on a straight line sum to 180°:
⇒ m∠ACD + 4x = 180°
⇒ m∠ACD + 4x - 4x = 180° - 4x
⇒ m∠ACD = 180° - 4x
Exterior Angle Theorem
The exterior angle of a triangle is equal to the sum of the two non-adjacent interior angles of the triangle.
⇒ m∠DAC + m∠ACD = m∠FDC
⇒ 2x + (180° - 4x) = 124°
⇒ -2x + 180° = 124°
⇒ -2x + 180° - 180° = 124° - 180°
⇒ -2x = -56°
⇒ -2x ÷ -2 = -56° ÷ -2
⇒ x = 28°
To find m∠ACD, substitute the found value of x into the expression for the angle:
⇒ m∠ACD = 180° - 4x
⇒ m∠ACD = 180° - 4(28°)
⇒ m∠ACD = 180° - 112°
⇒ m∠ACD = 68°

A two-sample t-test for a difference in means was conducted to investigate whether defensive players on a football team can bench-press more weight, on average, than
offensive players. The conditions for inference were met, and the test produced a test statistic of t = 1.083 and a p-value of 0.15.
Based on the p-value and a significance level of a = 0.05, which of the following is the correct conclusion?
Submit
Reject the null hypothesis because 0.15 > 0.05. There is not convincing evidence that defensive players can bench-press more weight, on average, than
offensive players.
B
Reject the null hypothesis because 0.15 > 0.05. There is convincing evidence that defensive players can bench-press more weight, on average, than
offensive players
с
Fail to reject the null hypothesis because 0.15 > 0.05. There is not convincing evidence that defensive players can bench-press more weight, on average,
than offensive players,
D
Fail to reject the null hypothesis because 0.15 > 0.05. There is convincing evidence that defensive players can bench-press more weight, on average,
than offensive players
Fail to reject the null hypothesis because 0.15 > 0.05. There is convincing evidence that defensive players can bench-press the same amount of weight,
on average, as offensive players.
Answer:
Fail to reject the null hypothesis because 0.15>0.05
. There is not convincing evidence that defensive players can bench-press more weight, on average, than offensive players.
Step-by-step explanation:
Since P>a we can not reject the null hypothesis. We cannot conclude the alternative hypothesis in context.
Mike is a cashier. He works 35 hours and is paid a total of £217
What is Mike's hourly rate of pay? (2 marks)
Your answer
Answer:
Answer vary :
Mike is paid $6.20 per 1 hour.
Step-by-step explanation:
honestly in my opinion that’s the answer.
‘what is happening is we need to find out how much he is paid for only one hour.
knowing that mike is paid 217 in 35 hours we divide
- 217 divided by 35 = 6.2
and that’s the answer to check if it’s right we multiple 6.2 by 35
- 6.2 times 35 = 217
wich shows it is correct.
and that is how I came to that solution.
During each week, John buys 3 new art pieces. Write an equation that shows the relationship between the numbers of art pieces x and the total number of art pieces he owns y
select one
A. y = 3x
B. y = 9x
C. x = 3y
D. y = x
Answer:
The correct answer is A. y=3x.
The total amount of art pieces he owns is equal to three times the number of pieces x.

Which of the following tables represents a linear function with the same slope as y=2-3x?
Table (C) represents the same slope -3 as the line y = 2 - 3x.
What is slope?The value of the steepness or the direction of a line in a coordinate plane is known as the slope of a line, often known as the gradient. Given the equation of a line or the coordinates of points situated on the straight line, slope can be determined using a variety of techniques.
The formula for slope between two points (x₁, y₁) and (x₂, y₂) is,
m = (y₂ - y₁)/(x₂ - x₁)
The given equation is,
y = 2 - 3x
The slope of the equation m = -3.
To find the slope of the table, take any two points, because given line is straight line. Therefore, slope will be equal for every point.
(A)
Slope m = (5-2)/(1-0) = 3
(B)
Slope m = (8-10)/ 4-2 = -2 / 2 = -1
(C)
Slope m = (7-10)/1-0 = -3.
Hence, slope of table (C) is -3.

i need to find the 9th term of this sequence
9514 1404 393
Answer:
26,244
Step-by-step explanation:
The sequence is geometric with a common ratio of -3. The general term is ...
an = (a1)r^(n-1)
The first term is 4, so we have ...
an = 4·(-3)^(n-1)
For n=9, we find the 9th term to be ...
a9 = 4·(-3)^(9-1) = 4·3^8
a9 = 26,244

When -3 is raised to an even power, the sign of the product is positive, the same as 3 raised to that power.

Which of these describes the equation 3x + 7y = 8?
Select each correct answer.
A function
B. linear
C. nonlinear
D. proportional
E.
When x is 0, y is
F. When y is 2, x is 2 or -2.
According to the linear function concept, the correct answer is:
B. linear
Additionally:
When x = 0, [tex]\frac{8}{7}[/tex].When y = 2, x = -2.What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.In this problem, the function is:
[tex]3x + 7y = 8[/tex]
Placing into standard format:
[tex]7y = 8 - 3x[/tex]
[tex]y = \frac{8}{7} - \frac{3x}{7}[/tex]
Hence it is a linear function.
When x = 0:
[tex]y = \frac{8}{7} - \frac{3(0)}{7} = \frac{8}{7}[/tex]
When y = 2:
[tex]y = \frac{8}{7} - \frac{3x}{7}[/tex]
[tex]2 = \frac{8}{7} - \frac{3x}{7}[/tex]
[tex]8 - 3x = 14[/tex]
[tex]3x = -6[/tex]
[tex]x = -\frac{6}{3}[/tex]

Answer:
1402 tiles
Step-by-step explanation:
so in order to find the amount of glass tiles we will first need to find the surface area of the box
so the surface area formula for a rectangular prism is
2 (wl * hw* hl)
w- width
h- height
l- length
so the width would be 18centimeters
the height would be 7 cm
and the length would be 23 cm
therefore if we plug in the measurements into the equation it will give us a total surface area of
1402cm^2
therefore if Dimitri wants to cover the box with 1cm glass tiles then we take the 1402cm and divide it by 1cm leaving us with the same answer of
1402 tiles
