Answer:
[tex]A=283.528736986[/tex]
Step-by-step explanation:
The formula for the area of a circle is:
[tex]A=\pi \times r^2[/tex]
Remember that the radius is half the diameter, we are given the diameter which is 19, which means we need to find the radius:
[tex]d=19[/tex]
[tex]19\times\frac{1}{2} =9.5[/tex]
[tex]r=9.5[/tex]
Substitute and solve:
[tex]A=\pi \times9.5^2[/tex]
[tex]9.5^2=9.5\times9.5=90.25[/tex]
[tex]\pi \times90.25=283.528736986[/tex]
[tex]A=283.528736986[/tex]
Since the question doesn't say to round the area is "283.528736986."

Find QR - Will mark brainliest
Answer:
26
Step-by-step explanation:
Answer:
QR = 30
Step-by-step explanation:
GHI ~ PQR means that PQR is the same shape and length ratios as GHI but is a different size.
All of the leg lengths of GHI are multiplied by something to get the leg lengths of PQR.
You're given the leg lengths 12 and 20. So you need to find out what 12 is multiplied by to get to 20. 12 * 5/3 = 20.
So multiply 5/3 by the other leg length 18.
18 * 5/3 = 30
So QR = 30

Some girls are standing in a circle. The teacher makes them do a headcount. Bianca says one, her neighbour says two and so on. If they count in a clockwise direction, Antonia says five. If they count in an anticlockwise direction, Antonia says eight. How many girls are forming the circle?
Answer:
11
Step-by-step explanation:
See the attached image: the outer numbers count girls clockwise, showing Antonia at point J. The inner numbers show counting anticlockwise, showing Antonia as number 8, then continuing the count past her.
Aha! The inner and outer numbers always sum to 13.
But anticlockwise #12 really counted herself as #1 (she's being counted twice), so there aren't 12 girls, there are 11.
If you're not convinced, draw a picture with, say, 5 girls in it, number them counting both ways.
A school is arranging chairs in rows for an assembly. $11$ chairs make a complete row, and right now there are $110$ chairs total. The school wants to have as few empty seats as possible, but all rows of chairs must be complete. If $70$ students will attend the assembly, how many chairs should be removed?
The number of chairs that should be removed, for there to be as few empty seats as possible but for all rows of chairs to be complete, is 33 chairs.
How to find the chairs to be removed ?The number of chairs that make up a row is 11 chairs and there are to be 70 students in attendance. The number of rows that would take the students is therefore:
= Number of students / Number of rows
= 70 / 11
= 6. 36
= 7 rows rounded up
The number of rows needed is 7 rows which means the number of chairs would be:
= 7 rows x 11 chairs per row
= 77 chairs
The number of chairs to be removed is:
= Total chairs - Chairs needed
= 110 - 77
= 33 chairs

N 2003, an organization surveyed adult Americans and asked about a certain war, "Do you believe the United States made the right or wrong decision to use military force?" Of the adult Americans surveyed, stated the United States made the right decision. In 2008, the organization asked the same question of adult Americans and found that believed the United States made the right decision. Construct and interpret a 90% confidence interval for the difference between the two population proportions, .
Complete question :
In March 2003, the Pew Research Group surveyed 1508 adult Americans and asked, "Do you believe the United States made the right or wrong decision to use military force in Iraq?" Of the 1508 adult Americans surveyed, 1086 stated the United States made the right decision. In August 2010, the Pew Research Group asked the same question of 1508 adult Americans and found that 618 believed the United States made the right decision. Construct and interpret a 90% confidence interval for the difference between the two population proportions
Answer:
(0.282 ; 0.338)
We are 90% confident that the proportion of adults in the U.S who believe that the United States made the right decision in 2003 lies between 0.282 and 0.338, higher than the proportion of adult Americans in 2010 who believe the same.
Step-by-step explanation:
Given :
p = x / n
p1 = 1086/1508 = 0.72
p2 = 618/1508 = 0.41
Confidence interval :
(p1 - p2) ± margin of error
Margin of Error = Zcrit*√p1(1-p1)/n1 + p2(1-p2)/n2
Zcrit at 90% = 1.645
1 - p1 = 1 - 0.72 = 0.28
1 - p2 = 1 - 0.41 = 0.59
MOE = 1.645*√(0.72*0.28)/1508 + (0.41*0.59)/1508
MOE = 1.645 * 0.0171492 = 0.0282105
(p1 - p2) = (0.72 - 0.41) = 0.31
Lower boundary = 0.31 - 0.0282 = 0.2818
Upper boundary = 0.31 + 0.0282 = 0.3382
(0.282 ; 0.338)
We are 90% confident that the proportion of adults in the U.S who believe that the United States made the right decision in 2003 lies between 0.282 and 0.338, higher than the proportion of adult Americans in 2010 who believe the same.

What is the value of k in the quadratic polynomial 3x2 2kx 3 if X − 12 is one of the zeroes of it?
The values of k are 3, – 3 for which roots of the quadratic equation are real and equal.
What is a quadratic equation?
An equation containing one term in which the unknown is squared and no term in which it is raised to a power higher than 2.
Given: 3x² + 2kx + 3 = 0
Comparing with standard quadratic equation ax² + bx + c = 0
a = 3 b = 2k c = 3
Given that the roots of the equation are real and equal
Thus, D = 0
Discriminant D = b² – 4ac = 0
(2k)² – 4.3.3 = 0
4k² – 36 = 0
4k² = 36
k² = 9 taking square root on both sides
k = 3 or k = – 3
Hence, The values of k are 3, – 3 for which roots of the quadratic equation are real and equal.

Lia bought 4 3/5 pound of trail mix. She gave 3/5 of it to her iter. How much did give away?
Lia gave away 3/5 of the trail mix, which is equal to 2 2/5 pounds.
Lia bought 4 3/5 pounds of trail mix. She gave 3/5 of it to her iter.Since Lia bought 4 3/5 pounds of trail mix, we can express this as 4 + 3/5 pounds, or 9/5 pounds.
To find out how much trail mix Lia gave away, we can multiply 9/5 by 3/5.
3. 3/5 multiplied by 9/5 is equal to 27/25.
To simplify this fraction, we can divide both the numerator and denominator by 3.
27/25 can be simplified to 9/5 or 2 2/5 pounds.
Therefore, Lia gave away 2 2/5 pounds of the trail mix.

If the length of ▁AB = -3y+54, the length of ▁BC = 5y+ 2, and the length of ▁CD is 6y + 9, find the value of y.
The value of 'y' in the isosceles trapezoid ABCD is 14 and this can be determined by using the properties of isosceles trapezoid.
What is Triangle ?
Triangle can be defined as which contains three sides, three angles and the sum of the angles is 180 degrees.
Given ,
ABCD is an isosceles trapezoid with legs AB and CD and base BC.
If the length of AB is (7y - 4),
the length of BC s (4y - 6),
and the length of CD is (8y - 18).
The two legs are of equal length In any isosceles trapezoid that means:
7y - 4 = 8y - 18
Add 18 on both sides in the above equation.
7y - 4 + 18 = 8y - 18 + 18
7y + 14 = 8y
Now, subtract 7y on both sides in the above equation.
7y + 14 - 7y = 8y - 7y
Simplify the above expression in order to get the value of 'y'.
