Before conducting the test, the doctor determines that the power of the test to reject the null hypothesis when μ = 98 using α = 0.01 and n = 10 is 0.2474.

You and two of your friends go to eat pizza

together. There are two deals:

1. 10% off of 1 pizza )

2. 30% off of 3 pizzas

Do you want to each pay separately and get

10% off of your bill, or do you want to split the

bill 3 ways and get 30% off of 3 pizzas?

Write a response that convinces your teacher

Answers

Answer:

The second deal offers a lower cost for the three friends.

Step-by-step explanation:

Let consider that each pizza has a price [tex]c_{o}[/tex]. Now, we proceed to check the total cost for each case, the better choice is whose total cost after discounts is the lowest.

Case 1 - 10 % off of 1 pizza (Split costs and buy 3 pizzas separately)

[tex]C = 0.9\cdot C_{o} + 0.9\cdot C_{o} + 0.9\cdot C_{o}[/tex]

[tex]C = 2.7\cdot C_{o}[/tex]

The cost for each person is:

[tex]c = \frac{C}{3}[/tex]

[tex]c = 0.9\cdot C_{o}[/tex]

Case 2 - 30 % off of 3 pizzas (Split costs and buy 3 pizzas in a row)

[tex]C = 0.7\cdot (3\cdot C_{o})[/tex]

[tex]C_{o} = 2.1\cdot C_{o}[/tex]

The cost for each person is:

[tex]c = \frac{C}{3}[/tex]

[tex]c = 0.7\cdot C_{o}[/tex]

The second deal offers a lower cost for the three friends.

If the equation of a circle is (x + 4)2 + (y - 612 = 25, its center point is
(4,6)
(4,6)
(4,-6)

Answers

Answer:

Center point: [tex](-4,6)[/tex]

Radius: [tex]r=5[/tex]

Step-by-step explanation:

The equation of a circle is [tex](x-h)^2+(y-k)^2=r^2[/tex] where [tex](h,k)[/tex] is the center point of the circle and [tex]r[/tex] is the radius of the circle.

Given our equation [tex](x+4)^2+(y-6)^2=25[/tex], we can see that [tex](h,k)[/tex] is [tex](-4,6)[/tex] and since [tex]r^2=25[/tex], our radius is  [tex]r=\sqrt{r^{2} } =\sqrt{25} = 5[/tex]

Therefore, the center point is [tex](-4,6)[/tex] and the radius is [tex]r=5[/tex]

Solve for the length of x

Answer:

[tex]\boxed {\boxed {\sf x\approx 63.7}}[/tex]

Step-by-step explanation:

This is a right triangle. We know this because there is a small square in the corner representing a 90 degree/right angle. Therefore, we can use the right triangle trigonometry ratios.

sinθ= opposite/hypotensue cosθ= adjacent/hypotenuse tanθ= opposite/adjacent

We are given angle A which measures 37 degrees.

Side BC which measures 48 is opposite angle A and the unknown side, x, is next to or adjacent to angle A.

We should use tangent.

[tex]tan \theta= \frac{opposite}{adjacent}}[/tex]

[tex]tan37= \frac {48}{x}[/tex]

Since we are solving for x, we must isolate the variable. First, cross multiply. Multiply the first numerator and the second denominator, then the first denominator and second numerator.

[tex]\frac {tan37}{1}=\frac {48}{x}[/tex]

[tex]tan37*x=48*1[/tex]

[tex]tan37*x= 48[/tex]

x is being multiplied by the tangent of 37. The inverse of multiplication is division, so we divide both sides by the tangent of 37.

[tex]\frac {tan37 *x}{tan37}=\frac{48}{tan37}[/tex]

[tex]x= \frac{48}{0.7535540501}}[/tex]

[tex]x=63.69815144[/tex]

Even though it is not specified, let's round to the nearest tenths place. The 9 in the hundredth place tells us to round the 6 up to a 7.

[tex]x\approx 63.7[/tex]

Each card in a set of cards has one of the letters from the word MATHEMATICS. The cards are shuffled. Suppose you draw a card from the set of cards, record the letter, return the card to the set, and shuffle the cards. You repeat this experiment 22 times. Would you expect the experimental probability of drawing a vowel to be the same as the theoretical probability? YES or NO and Explain you answer

Answers

Answer:

No

Step-by-step explanation:

Theoretical probability is the expected probability of anything. For example we expect a probability of 1/6 for each number when we roll a die .

Experimental Probability is the one that is obtained by the actual experimenting of rolling the die.

The theoretical probability is the example of perfect probability and experimental probability  is the example of actual occurrence.

Their formulas are

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

Experimental Probability =  number of favorable outcomes/ total number of actual outcomes

If we a roll a fair die several times we may get 2 repeated number of times or any other number that is on the die.

So the experimental probability is bit different from the theoretical probability.

Now if the cards are shuffled and the experiment is repeated 22 times

experimental probability of drawing a vowel  would not  be the same as the theoretical probability because n is small.

If n→1000 or more

n→∞

According to K. Pearson or Buffon when n tends to infinity the  theoretical probability becomes equal to experimental probability.

They experimented this on a coin and put forward their results.

[tex]log_b 1 = log_b b^0[/tex]

Multiply by 0

[tex]log_b 1 = 0[/tex]

Answer:

logb 1 = 0

Step-by-step explanation:

Suppose that logb 1 = x.

Using the definition of a logarithm, bx = 1.

The only way a number that’s not equal to 1 can be raised to a power and equal 1 is if the exponent is 0. So, x = 0.

Therefore, logb 1 = 0.

B) 16.8 in

C) 18.2 in

D) 20.1 in

Answers

See the diagram of the circumscribed polygon attached below:

Answer:

A. 14.2 in.

Step-by-step explanation:

Perimeter = 3.7 + 3.6 + 3.4 + 1.9 + g

Let's find g.

a = 1.9 in. (Tangents drawn from an external point of a circle are congruent)

b = 3.4 - 1.9 = 1.5 in.

b = c = 1.5 in. (Tangents drawn from an external point)

d = 3.6 - 1.5 = 2.1 in.

d = e = 2.1 in. (Tangents drawn from an external point)

f = 3.7 - 2.1 = 1.6 in.

f = g = 1.6 in. (Tangents drawn from an external point)

✔️Therefore,

Perimeter = 3.7 + 3.6 + 3.4 + 1.9 + 1.6 = 14.2 in.

Parts for an automobile repair cost ​$173. The mechanic charges ​$32 per hour. If a person receives an estimate for at least ​$253 and at most ​$285 for fixing the​ car, what is the time interval that the mechanic will be working on the​ job?

Answers

Answer:

58

Step-by-step explanation:

The time interval for the mechanic for this job is at least 2 hours and 30 minutes or at most 3 hours and 30 minutes.

What is at least and at most concept ?

At least means lower limit of a given contrast and at most means higher limit of a given contrast.

According to the given question parts for an automobile repair cost ​173 dollars and the mechanic charges 32 dollars per hour.

Given the person receives a cost of at least 253 dollars.

∴ The mechanic's total rate is ( 253 - 173 ) dollars which is = 80 dollars.

Also given the mechanic charges 32 dollars per hour so the time mechanic work for is at least (80/32) hours which is = 2.5 hours or 2 hours and 30 minutes.

In the later case when the owner receives a bill of 285 dollars the total rate of mechanic is

= ( 285 - 173 ) dollars.

= 112 dollars.

So, the mechanic have worked for (112/32) hours which is

= 3.5 hours or 3 hours and 30 minutes.

Rate (Quilts per Hour) Time (Hours) Fraction Completed Renee One-sixteenth x Genera One-twelfth x 6 hours 6 and six-sevenths hours 8 and six-sevenths hours 28 hours

This is calculated as:

1/ number of hours for Renee + 1/ number of hours for Geneva = 1/ Total number of hours that they can do it together

= 1/16 + 1/12 = 1/T

Lowest common denominator = 192
