The manager of a fast food restaurant is supposed to serve coffee that is 160 degrees Fahrenheit. A random sample of 20 cups of coffee reveal that the mean temperature is 151 degrees Fahrenheit with a standard deviation of 3 degrees. The manager would like to conduct a t-test for the population mean temperature of all cups of coffee served at this restaurant. Are the conditions for inference met?

No, the random condition is not met.
No, the 10% condition is not met.
No, the Normal/large sample condition is not met.
Yes, all conditions for inference are met.

Answer:

Approximately 3 times, Jake will be able to hit the ball in a game of 10 balls

Step-by-step explanation:

Batting average determine the % share of time the bat hit the ball.

Jake's probability of hitting a ball = 0.34

Jake plays 10 games.

Probability of hitting a ball in a game is

10 * 0.34 = 3.4

Approximately 3 times, Jake will be able to hit the ball in a game of 10 balls

Answer:

P(A or B) = 39%

Step-by-step explanation:

If A and B are mutually exclusive, they cannot occur at the same time, therefore their probabilities are added. This means P(A or B) = P(A) + P(B) = 23% + 16% = 39%

Answer:

p = 10

Step-by-step explanation:

3p + 10 + 5p = 90

8p + 10 = 90

90 - 10 = 80

80 / 8 = 10

Answer:

The answer is "The claim is plausible because 3 head movements per minute are contained within the interval".

Step-by-step explanation:

The wet-growing process of creation, located in western Florida, is researched by animal researchers. Food production is the process of finding food. The researchers had collected a sampling of 63 lizards with the number of head motions per minute to investigate such behavior. The sample-based confidence interval of 95% is given as hand gestures of 2.7±0.62 per minute. Depending on the interval, a statement of 3 hand gestures is plausible per minute then within the interval, there have been three head motions per minute.

Step-by-step explanation:

Answer:

12.5

Step-by-step explanation:

50÷4=12.5

Answer:

≈ 7.07m

Step-by-step explanation:

Let the length of a side of a square

= a metre

a² = 50 m²

[tex] \sf{a = \sqrt{50m {}^{2} }}[/tex]

[tex] \sf{ = \sqrt{2 \times 5 \times 5m {}^{2} }}[/tex]

[tex] \sf{ = 5 \sqrt{2m} }[/tex]

≈ 5x 1.414

≈ 7.07 m

therefore

side of triangle

[tex] \sf \: = 5 \sqrt{2m} [/tex]

B. 24 in ^2

Step-by-step explanation:

To find this follow these steps:

1. find the area of the first square: 6 inches times 3 inches so you get 18 inches squared

2. Find the area of the second square : 3 inches times 2 inches you get 6 inches squared

Have a wonderful day!

Answer: C-26

Step-by-step explanation: First you need to figure out how many total cars he needs to sell through the year by multiplying 12 by 18. This should get you 216. Now, we need to add all of his actual stats that we have so far to get a total of 190 cars sold. We know he needs 216 total by the end of the year, so we just have to subtract 190 from 216 to get our answer, 26.

Answer:

The probability you will get a head at least once is 50%.

Step-by-step explanation:

Since the question is asking about the probability you will get, we can assume we’re answering based on theoretical probability. This type of probability is based on logic.

A coin always has two sides, one with head and the other with tails. So we can easily represent this as half and half. 1/2 as a fraction. 0.5 as a decimal. 50% as a percent. This means that P(H) will be equal to any one of these as they are all the same. The same can be said for the probability that a head does not appear, in other words, a tail appears. The reason being that the probability is split evenly between the two. This will again mean that P(T) will equal to any one of those.

So, A = 50% and B = 50%. The probability you will get a head at least once is 50%.

Answer:

Centre is [tex](7,11)[/tex]

Radius is [tex]6[/tex]

Step-by-step explanation:

The general equation for a circle is written in the form [tex](x-a)^2+(y-b)^2=r^2[/tex] , where [tex](a,b)[/tex] is the centre of the circle, and [tex]r[/tex] is the radius.

For your circle, [tex](x-7)^2+(y-11)=36[/tex], we can compare it with the general equation to find the centre and radius.

[tex]-a = -7[/tex]

[tex]-b = -11[/tex]

[tex]r^2 = 36[/tex]

Therefore, [tex]a=7[/tex], [tex]b=11[/tex] and [tex]r=6[/tex].

Centre at [tex](a,b)[/tex] which is [tex](7,11)[/tex] .

Answer:

x = 4

y = 10

Step-by-step explanation:

3x + 2y = 32 (Multiply this equation by -3)

9x - 3y = 6

-9x - 6y = -96

9x - 3y = 6

-9y = -90

y = 10

3x + 2y = 32

3x + 2(10) = 32

3x + 20 = 32

3x = 32 - 20

3x = 12

x = 4

Way 1

By reducing  the length of the side 4 to 3.60

Way 2

By increasing the length of side 7 to 7.21

Step-by-step explanation:

The complete question is attached in the image

Solution

1.

Both the triangles are right angled triangle

For triangle 1

[tex]7^2 = 2^2 + a^2\\49 = 4 + a^2\\a^2 = 45\\a = 3\sqrt{5}[/tex]

For triangle 2

[tex]4^2 = x^2+x^2\\2x^2 = 4*4\\x^2 = 8\\x = 2\sqrt{2}[/tex]

Yes both their methods works.

Step-by-step explanation:

Trust me

Answer: Question 1 : x + 3 = 14 and x = 14 - 3

Question 2: y/5 = 60 and y = 60 x 5

Solve each eqaution

2x = 5 : answer : x = 5/2

y + 1.8 = 14.7 (subtract 1.8 on each side) : answer = 12.9

6 = 1/2z (combine terms) Answer 12

3 1/4 = 1/2 + W (Convert mixed numbers to improper fractions) answer = -1 9/13

2.5t = 10 : answer : 4

2.5t-(10)=0

t=10/2.5

(For 3 I can't draw the diagram asked. sorry)

21.2 - 0.82 = 20.38

2.05 x 0.004 = 0.00820.

Lin is right. Jada method 60 divided by 4 (1/4 of 60) which gives you 15. Andre method: 25/100 x 60 = 50.

Answer:

your answer is 628.32cm :)

Answer:  I think it is 628.32

Step-by-step explanation: You have to multiply the radius by two to get the diameter and then multiply that by 3.14(PI)

100 x 2=200    

3.14 x 200=628.32
