If a regular polygon has one exterior angle measuring 1°, then it has_______ sides.

Answers

Answer 1

Answer: The measure of the exterior angle of a regular polygon is given by the formula $(360)/(n)$ where $n$ is the number of sides.
To find the number of sides of a polygon with the exterior angle measuring $1^(\circ)$ we have to solve the equation $(360)/(n)=1$ .

$(360)/(n)=1|\cdot n\nn=360$

It has 360 sides.

Tom has offered to sell Julian his motorcycle for $1,200. Julian knows this is a very good deal, since the same motorcycle can be purchased at the dealership for $1,800. Since Julian doesn’t have $1,200 and Tom does not accept credit cards, they both think a cash advance might be a good idea. Julian’s credit card company can offer him a cash advance for the $1,200 he needs at an interest rate of 26%. He would then pay off the balance in 24 months. Should Julian use the cash advance to purchase the motorcycle? a. No. Julian would be paying too much in interest to warrant using a cash advance. b. Yes. Even with the interest, the total cost of the motorcycle would be less than at the dealership. c. Yes. The interest rate on the cash advance is low. Julian will not have to pay much interest on the cash advance. d. No. The high interest rate on the cash advance would make the purchase of the motorcycle almost twice than the price at the dealership.

A pilot flew a jet from location A to B, a distance of 2500 meter,on the return trip the average speed was 20 percent faster than the outbound speed,the round-trip took 9 hours 10 minutes . What is the jet's speed from A to B.

Answers

Answer: The jet's speed from A to B would be 5.5 km/hr.

Step-by-step explanation:

Since we have given that

Distance = 2500 meter

Outbound speed be x

Average speed be $(100+20)/(100)x=(120)/(100)x=1.2x$

Time = 9 hours 10 minutes = $9(10)/(60)=9(1)/(6)=(55)/(6)$

According to question, it becomes,

$(2.5)/(x)+(2.5)/(1.2x)=(55)/(6)\n\n(1.2x+x)/(1.2x^2)=(55)/(6* 2.5)\n\n(2.2x)/(1.2x^2)=(11)/(3)\n\n(2.2)/(1.2x)=(11)/(3)\n\n2.2* 3=1.2x\n\n6.6=1.2x\n\n(6.6)/(1.2)=x\n\nx=5.5\ km/hr$

Hence, the jet's speed from A to B would be 5.5 km/hr.

A chocolate factory produces mints that weigh 10 grams apiece. The standard deviation of the weight of a box of 10 mints is 3 grams. You buy a box of mints that weighs 95 grams. What is your confidence that the box you bought did not come from the factory?A 90%
B 95%
C 10%
D 5%

Answers

Answer: Option 'A' is correct.

Step-by-step explanation:

Since we have given that

Population Mean weight ( $\mu$ )= 10 grams a piece

Standard deviation of the weight of a box = 3 grams

Number of mints = 10

We need to buy a box of mints that weighs 95 grams.

Sample mean is given by

$x=(95)/(10)=9.5\ grams$

First we find out the standard error which is given by

$s=(\sigma)/(√(n))\n\n=(3)/(√(10))\n\n=0.94868$

Since it is normal distribution, so, we will find z-score.

$z=(x-\mu)/(s)\n\nz=(9.5-10)/(0.94868)\n\nz=-0.527\n\nz=-0.53$

The area to the left of a z-score of -0.53 = 0.29805.

So, it may be 90% or 95 % confidence.

For 95% confidence level,

$\alpha=(1-0.95)/(2)=0.025$

Similarly,

For 90% confidence level,

$\alpha=(1-0.90)/(2)=0.05$

We have little confidence that the box he bought did not come from the factory. that is much smaller than 0.05.

So, it is safe to assume 90% confidence.

So, we will get 90% confidence, critical value = 1.645

Margin of error is given by

$(Standard\ deviation)* (critical\ value)\n\n=0.94868* 1.645\n\n=1.56$

So, confidence interval will be

(10-1.56,10+1.56)

=(8.44,11.56)

Hence, Option 'A' is correct.

The right answer for the question that is being asked and shown above is that: "C 10%." A chocolate factory produces mints that weigh 10 grams apiece. The standard deviation of the weight of a box of 10 mints is 3 grams. You buy a box of mints that weighs 95 grams.
