75°, then determine the arc length of
Part B: If HY = 46 inches and mYX
YX
Answer:
[tex]\frac{115\pi }{6} \\or\\19.16666667\pi[/tex]
Step-by-step explanation:
Arc length is [tex]2\pi r*\frac{o}{360}[/tex]
r is 46 theta is 75
[tex]2(46)\pi *\frac{75}{360} \\92\pi *\frac{75}{360} \\\frac{6900\pi }{360} \\\frac{115\pi }{6} or 19.166666667\pi[/tex]
. y=-3x2 + bx + c; (1, 0)
find the unknown coefficients
Answer:
[tex]y = - 3 {x}^{2} + bx + c \\ when \: (1,0) \\ 0 = - 3( {1})^{2} + b(1) + c \\ 0 = - 3 + b + c \\ b + c = 3 - - - (.) \\ at \: (0,0) \\ 0 = c \\ c = 0 \\ hence \: b = 3[/tex]

The shape above is a trapezium, so we are going to use the formula for the area of a trapezium which is,
[tex]area = (\frac{a + b}{2} )h[/tex]
Plugging in our values,
[tex]area = ( \frac{2 + 8}{2} ) \times 3 = ( \frac{10}{2} ) \times 3 = 5 \times 3 = 15 {cm}^{2} [/tex]
So the area will be
[tex]15 {cm}^{2} [/tex]

Answer:
720°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 6 , then
sum = 180° × 4 = 720°

A student had 10 marks in mathematics. But he remembers only 7 of them:
1,1,2,2,3,4,5. The mode of the marks is 3 and the mean is 2.9. What are the
missing marks? Once you manage to find these marks, create a frequency
table for the students' scores and visualize the results with a bar chart.
Answer:
The missing marks are 3, 3, and 5.
Step-by-step explanation:
Since the mode is 3, that means it's the number that occurs most often. The numbers 1 and 2 occur twice so there must be at least 3 3's on the list. But since the mean is 2.9, the third mark cannot be a 3 because it will make the mean only 2.7 so the 3rd mark can be either a 4 or a 5. Using 5 will make the mean 2.9. I take it that you know how to make a bar graph for this problem.

8. When nominal GDP is $900 and the price index is 150, real GDP would equal
$60
$135
$600
$1,350
$6,000
Answer:
$600
Step-by-step explanation:
Gross domestic product is the total sum of final goods and services produced in an economy within a given period which is usually a year
Nominal GDP is GDP calculated using current year prices while Real GDP is GDP calculated using base year prices. Real GDP has been adjusted for inflation.
Price index measures how prices change over a period of time. It is a measure of inflation
Real GDP = (nominal / price index) x 100
($900 / 150) X 100 = $600
