Answer:
a = 25
Step-by-step explanation:
The exterior angles of a polygon sum to 360°
Sum the exterior angles and equate to 360
a + a + 40 + 51 + 55 + 54 + 2a + 60 = 360, that is
4a + 260 = 360 ( subtract 260 from both sides )
4a = 100 ( divide both sides by 4 )
a = 25

A botanist wishes to estimate the typical number of seeds for a certain fruit. She samples 41 specimens and counts the number of seeds in each. Use her sample results (mean = 54.7, standard deviation = 5.3) to find the 90% confidence interval for the number of seeds for the species. Enter your answer as an open-interval (i.e., parentheses) accurate to one decimal place (because the sample statistics are reported accurate to one decimal place).
Answers
Answer:
(53.3; 56.1)
Step-by-step explanation:
Given that:
Sample size, n = 41
Mean, xbar = 54.7
Standard deviation, s = 5.3
Confidence level, Zcritical at 90% = 1.645
Confidence interval :
Xbar ± Margin of error
Margin of Error = Zcritical * s/sqrt(n)
Margin of Error = 1.645 * 5.3/sqrt(41)
Margin of Error = 1.362
Lower boundary = 54.7 - 1.362 = 53.338
Upper boundary = 54.7 + 1.362 = 56.062

m∠MYX =?? degrees
° m∠ZMW =?? degrees
Answers
Answer:
<ZMW =90
<MYX = 29
Step-by-step explanation:
Remark
A Rhombus has a lot of peculiar properties. One of them is that the diagonals intersect at right angles. That means <ZMW =90 degrees.
Since the angle XMY = 90 degrees, it follows that <MXY + <MYX = 90 degrees because the third angle of the triangle = 90.
<MXY = 61 is given
So 61 + <MYX = 90 Subtract 61 from both sides.
<MYX = 90 - 61
<MYX = 29
m<MYX=29°
m<ZMW=90 diagonal bisect each other perpendicularly
Step-by-step explanation:
m<MYX+m<MXY+m<XMY=180 sum of interior angle of the triangle
here
m<XMY=90° diagonal bisect each other perpendicularly
m<MYX+61°+90°=180
m<MYX=180-151=29°
at the school book fair, Henry brings $10.00. He purchases a book for $8.50, plus a 6% sales tax. How much money in change will henry receive ?

You purchase a bond with a coupon rate of 8.5% and par value of $2,000. The value of the bond rose to $2,500. What is the bond?
Answers
Answer:
The bond yield is 6.80%.
Step-by-step explanation:
Note: This question is not complete. The complete question is therefore provided before answering the question as follows:
You purchase a bond with a coupon rate of 8.5% and par value of $2,000. The value of the bond rose to $2,500. What is the bond yield?
The bond can now be calculated as follows:
Coupon payment = Coupon rate * Bond per value = 8.5% * $2,000 = $170
Bond yield = Coupon payment / Current value of the bond = $170 / $2,500 = 0.068, or 6.80%
Therefore, the bond yield is 6.80%.

Amy buy 6 tickets for a match, 3 adult and 3 children tickets. Each ticket costs £7.27. She gets £2.75 off on each children's ticket. How much does Amy finally pay for 6 tickets?
Answers
Answer:
$35.37
Step-by-step explanation:
Answer:
Amy pays £35.37 for 6 tickets
Step-by-step explanation:
since each ticket costs the same amount, we can do 6(£7.27) to find out how much she originally had to pay before she gets £2.75 off on each children's ticket
6(£7.27)=£43.62
now, since she gets £2.75 off on each children's ticket, and there are three children, to find out how much money she got off total:
3(£2.75)=£8.25
finally, we have to subtract £43.62-£8.25 to find the total amount Amy finally pays for 6 tickets
£43.62-£8.25=£35.37
so, Amy pays £35.37 for 6 tickets
