The probability of spinning an odd number, not flipping heads, then not spinning a 6 is
__

Answers

Using it's concept, it is found that the probability of spinning an odd number, not flipping heads, then not spinning a 6 is:

[tex]p = \frac{20}{81} = 24.69\%[/tex]

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem:

There are 5 odd numbers in the spinner, out of 9, hence the probability of spinner an odd number is 5/9.The coin is fair, hence the probability of flipping tails = not heads is of 1/2.Out of the 9 numbers in the spinner, only one is six, hence the probability of not spinning a 6 is of 8/9.

Then, the probability of the compound event is:

[tex]p = \frac{5}{9} \times \frac{1}{2} \times \frac{8}{9} = \frac{20}{81} = 24.69\%[/tex]

Answers

Answer:

Step-by-step explanation:

We know that a straight angle is equal to 180°. Therefore, 120°+(a)=180°

We can solve for (a) by subtracting 120 from 180, which is 60.

180-120=60

m∠a+120°=180°

m∠a=60°

We know that the sum of all angles in a triangle is 180°.

Therefore, (a)+60°+(b)=180°

We know that (a) is equal to 60°, so our new equation is:

60°+60°+b=180°

60+60=120

180-120=60

m∠b+60°+60°=180°

m∠b=60°

Answer:

B

Step-by-step explanation:

I am not sure what your teacher wants but I guess you can say the following:

at n = 1, the cost is 4 dollars.

at n = 2, the cost is 8 dollars.

This trend is the same where the cost increases by 4 as n increases by 1. This means the C = 4n. We can check this by plugging values into the equation.

For the first row, C = 4, n = 1, and so the equation satisfies it. For the second row in the table, C = 8, n = 2, and so the equation works again. The other data points also agree using the equation.

Answer:

1: Tip, $2.23

2: Tax, $0.74

3: Total, $17.87

4: Split, $5.95

Step-by-step explanation:

To find the tip, you must multiply the tip percentage by the bill, (which has not been taxed yet). The tip is 15%, which is equivalent to 0.15. The tip multiplied by the bill (0.15×14.90) equals $2.23.

To find the tax, you do the same as you did with the tip. The tax is 5%, which equals 0.05. The tax multiplied by the bill, (0.05×14.90) equals $0.74. The total cost is the bill, tip, and tax added together, (14.90+2.23+0.74) equals $17.87. To find out how much each person will pay equally, you must divide the total bill by the amount of people, (17.87÷3) which equals $5.95.

Skye made a deposit of $625 into an account that earns 4% simple interest for 6 years. How much did Skye earn in interest at the end of 6 years?

Answers

Answer:

She will earn 150$

Step-by-step explanation:

4% = 0.04

0.04 x $625 = 25

Now we divide 25 by the number of years, which is 6.

6 x 25 = 150$

Therefore, Skye earns 150$ from interest over the course of 6 years.

a skydiver jumps out from the plane at 10,000 feet above the ground. the skydiver decends at a rate of 175 feet per seconds. how high in the air is the skydiver when he opens his parachute after 25 seconds?

Answers

Answer:

5625 feet

I hope it's helps you

Answer:

5625 feets

Step-by-step explanation:

Rate(feet/seconds) = height(feets)/time(seconds)

175 = x/25

x = 4375

After the skydiver opens his parachute the height reduces

Initial height – reduced height

10000 – 4375

= 5625 feets
