[tex]\boxed{\textsf{ The degree measure is \textbf{ 48}$^{\textbf{o}}$.}}[/tex]

Step-by-step explanation:

Here we are given radian measure which is 4π/15 radians . We know the relationship between Radian and Degree measure as ,

[tex]\qquad\boxed{\boxed{ \sf\pi rad = 180^o }}[/tex]

Put on the respective values ,

=> π rad = 180°

=> 1 rad = 180°/ π

=> 4π/15 rad = 180°/π × 4π/15

=> 4π/15 rad = 48 °

Answer:

Step-by-step explanation:

The experimental value of probability of the arrow landing on a section labeled with a multiple of 4 is 3/4 or 0.75

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

The probability that the arrow lands on a section labeled with a multiple of 4 is an experimental probability since it is based on the results of an actual experiment or trial.

The experimental probability is given by:

Experimental probability = Number of times the event occurred / Total number of trials

In this case, the event is the arrow landing on a section labeled with a multiple of 4, and the total number of trials is 60.

From the given information, we know that the arrow landed on a section labeled with a multiple of 4 on 45 out of 60 times.

So the experimental probability is:

Experimental probability = 45/60

Simplifying:

Experimental probability = 3/4

Hence , the experimental probability of the arrow landing a multiple of 4 is 3/4 or 0.75

Slope is -15/8

Final answer is -15/8

I hope this helps you!

Have  a nice day! :)

-

:D

Step-by-step explanation:

Slope is rise over run. This means your y is over your x. Start with subtracting your y values. It doesn't matter which way, just make sure you do the same with the x values. For this, I'll do it 6 - -9. The two negatives cancel out and make a positive, so your y value is 15. Now, do the same to the x values. -9 - -1 is -8. You're left with 15/-8. Since this can't be simplified, this is your final answer. Hope I helped!

Answer:

Step-by-step explanation:

Since x=-4 plug in the -4 into the equation to find y,

-5(-4)-4y=16

20-4y=16                                                                                                                             -20       -20                                                                                                                   __________

-4y=-4

-4y/-4=-4/-4

___________

y=1

So now you found both x and y so plug in both now to check if both are correct.

-5(-4)-4(1)=16

20-4=16

16=16

So both y and x are correct.

Answer:

A) v = T/2 - 5

Step-by-step explanation:

T = 10+2v

2v = T-10

v = (T-10)/2 = T/2-5

The equation that describes no. of DVDs that Ingrid can rent is A.              v = (T/2) - 5.

An equation states that terms on both sides of the equality sign are equal.

The monthly membership costs 10 dollars, and The rent for each DVD costs 2 dollars.

No. of DVDs that can be rented is denoted by v based on T.

The equation that describes the total cost of renting DVDs is,

T = 2v + 10.

∴ The equation that describes no. of DVDs that can be rented is

2v = T  - 10.

v = (T/2) - 5.

Answer:

9 Years

Step-by-step explanation:

Answer:

The change after five years is equal to -$100

Step-by-step explanation:

If the insurance payment is equal to P = N dollars, where P is a real number, we know that after one year, the payment decreaces by $20, so the new payment is:

P = N - $20

Then, after 5 years, the $20 dollars are discounted five times, so the payment will be:

P = N -5*$20 = N - $100

Then the total change after 5 years is equal to those $100 that are being subtracted in the last equation.
