What is the length of the arc shown in​ red?

Answers

Answer:

≈ 18.8 cm

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

The central angle is equal to the arc subtending it, that is 60°

  arc = 2πr × [tex]\frac{60}{360}[/tex]

        = 2π × 18 × [tex]\frac{1}{6}[/tex]

        = 36π × [tex]\frac{1}{6}[/tex]

        = 6π ≈ 18.8 cm ( to 1 dec. place )

(a) What is the ratio of roses to daisies?

(b) What is the ratio of all flowers in the vase to daisies?

Answers

Answer:

a) 4:3

b) 7:3

Step-by-step explanation:

No. of roses= 8

No. of daisies = 6

Total no. of flowers = 14

a) Ratio of roses to daisies = No. of roses/No. of daisies

8/6

= 4/3

= 4:3

the sample proportion?
A. 0.53
B. 0.51
C. 0.49
D. 0.50

Answers

Answer:

0.50

Step-by-step explanation:

The sample proportion to be found for 98% confidence interval is

D. 0.50.

What is a confidence interval?

The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval.

Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test.

In statistics, confidence is another word for probability.

Given, Sample = (0.47, 0.53).

Confidence interval = 98%.

Therefore, The sample proportion is,

= (0.47 + 0.53)/2.

= 1/2.

= 0.5.

So, The sample proportion is 0.50.

Sariya and Kate went to lunch and their total bill was $36.96. If they
left a 20% tip. How much would their total bill be?

Answers

Answer:

$ 44.352

Step-by-step explanation:

The bill of both of them was $36.96. And they gave a tip of 20%. So , the total amount paid will be ,

=> Amount = Bill + 20% of Bill

=> Amount = $36.96 + 20% of $ 36.96

=> Amount = $36.96 + 1/5 * $36.96

=> Amount = $36.96 + $7.392

=> Amount = $ 44.352

Hence the amount paid by them is $44.352.

Answer:

$44.352

Step-by-step explanation:

Their bill = $36.96

Tip = 20% of $36.96

= 20/100 × 36.96

= $7.392

Hence, their total bill = $36.96 + $7.392

= $44.352

One experiment had 10 players spinning, another experiment had 100 players spinning. Which experiment is more likely to come closer to matching its theoretical probability.

Answers

Answer: Experiment with 100 players sprinting

Step-by-step explanation:

When it comes to experiments using samples to find out the effect of a variable on an entire population by finding out the representative effect on the sample, the larger the size of the sample, the better.

A larger sample comes closer to being the actual size of the population so when this larger sample is experimented upon, the results it gives will be closer to the results that would be gotten if we experimented on the entire population. The 100 player sprinting experiment would therefore come closer to matching its theoretical probability.

An isosceles triangle has an angle that measures 110°. Which other angles could be in that isosceles triangle? Choose all that apply: 110 55 35 15

Answers

Answer:

35 degrees

Step-by-step explanation:

An isosceles triangle has two opposite sides. If the two angles are equal , it means the triangle is an isosceles. Because 90 degrees is greater than 45 degrees, the two sides with the same length, would have a smaller length than the third side

sum of angles in a triangle = 180

180 - 110 = 70

since 2 angles would be equal

70 / 2 = 35

A butcher purchases 50 chicks at the rate of Ts.60 per chick.10 of them died and he sold remaining chicks at the rate of Rs.80 per chick. Find profit or loss percentage.

Answers

Answer: 6.25%

Step-by-step explanation:

50 chicks were purchased at Rs. 60. The total cost of the chicks is:

= 50 * 60

= Rs. 3,000

10 of the chicks died which means the farmer was left with 40 chicks.

These chicks are sold at Rs. 80. Total revenue from the sales are:

= 40 chicks * 80

= Rs. 3,200

The profit is:

= 3,200 - 3,000

= Rs. 200

The percentage is:

= Profit / Revenue

= 200 / 3,200

= 6.25%

Answer:

The answer is $20.

The way we find how much each cookie is is by dividing 8 by 10. We get 0.8. So now we know each cookie costs 80 cents. So, for 25 cookies, all we need to do is multiply 25 and 0.8. When multiplied, you get the answer $20.

Answers

To solve it would be 14/5 but if it’s simplify it would be 5x=14

Answer:

x = 14/5

Step-by-step explanation:

2x-4= -x-6/2

multiply by 2 on both sides to get rid of the fraction

4x-8= -x-6

add both sides by 8 and both sides by x to get the constants on the right and the variables on the left

4x+x=6+8

combine like terms/simplify

5x=14

divide both sides by 5 to isolate the x

x=14/5
