1.) Phoebe has a hunch that older students at her high school are more likely to bring
a bag lunch than younger students, because they have grown tired of cafeteria
food. she takes a simple random sample of 80 sophomores and finds that 52 of
them bring a bag lunch. a simple random sample of 104 seniors reveals that 78 of
them bring a bag lunch. Does this data provide convincing evidence to support
Pheobe's hunch at the 5% significant level?

2.)Interpret the P-value in context

Answers

Answer 1

The data in this experiment is not convincing enough to prove the hypothesis.

What is convincing evidence?

In an experiment, convincing evidence means the data collected is relevant and accurate enough to prove the hypothesis. For the data to be considered convincing it should:

Prove the hypothesis: This condition is satisfied because the data collected can prove older students are more likely to bring a bag lunch.Be collected using random samples: This condition is satisfied because students were selected randomly.Consider the standard or norma: This condition is met because the research compares the number of sophomore students that bring a bag lunch vs the number of seniors.7

Moreover, the P-value should be always smaller than the significant level. In the case of this study, the P-value is 0.069, which means it is greater than the significant level 0.05 and this causes the data is not convincing enough.

Hey please help me this is an Angle sum theorem!!!

Answers

Answer:

900° and 1260°

Step-by-step explanation:

The sum of the interior angles of a polygon is calculated as

sum = 180° (n - 2) ← n is the number of sides

(2)

Here n = 7 , then

sum = 180° × 5 = 900°

(3)

Here n = 9 , then

sum = 180° × 7 = 1260°

Step-by-step explanation:

here's your solution

==> area of trapezium = 1/2*(sum of parrel side)*distance between them

==> area of trapezium = 1/2(7.7 + 14.3)*8.6

==> area of trapezium = 1/2*22*8.6

==> area = 11*8.6

==> area = 94.6 ft.sq

Answers

Answer:

Choice C

Step-by-step explanation:

The Equation of a circle is (x-h)^2+(y-k)^2=r^2, where h and k are the x and y coordinates respectively of the center of the circle, and r is the radius. Because the center here is (2, -5), we have (x-2)^2+(y- - 5)^2, and the two minuses become (y+5)^2. This eliminates A and B. The radius is 4, so r^2=16, and thus, we get C.

Answers

Hello!

This question is about which values you are changing when you are transforming an equation.

Let's go through the parent function for an absolute value equation and its various transformations.

[tex]y=a|b(x-c)|+d[/tex]

Since we are only looking at horizontal and vertical transformations, we only need to worry about the c and d values.

The c value of a function determines a function's horizontal position, and the d value of a function determines a function's vertical position.

One thing to note here is that the c value is being subtracted from the x value, meaning that if the function is being transformed to the right, you would actually be subtracting that value, while the d value behaves like a normal value, if it is being added, the function is transformed up, and vice versa.

Now that we know this, let's write each expression.

a) [tex]y=|x+2|+1[/tex]

b) [tex]y=|x+2|-1[/tex]

c) [tex]y=|x+3|[/tex]

d) [tex]y=|x+1|[/tex]

POSSIBLE POINTS: 0.71 An MP3 player has 60 songs stored on it. Of the songs, 21 are rock, 9 are rap, 18 are dance, and 12 are country. If songs are played randomly, find the probability of each event. A rap song is played​

Answers

Answer:

outcome for rock = 21/60 = 7/20

outcome for rap = 3/20

outcome for dance = 3/10 or 6/20

outcome for country 1/5, 2/10 or 4/20

Step-by-step explanation:

possible outcomes = 21+9+18+12 = 60

outcome for rock = 21/60 = 7/20

outcome for rap = 3/20

outcome for dance = 3/10 or 6/20

outcome for country 1/5, 2/10 or 4/20

The probability of playing a rap song is 3/20.

What is probability?

Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.

For the given situation,

0.71 An MP3 player has 60 songs.

The sample space is the number of songs stored in MP3 player.

⇒ [tex]n(s)=60[/tex]

Number of rock songs, [tex]n(rock)=21[/tex]

Number of rap songs, [tex]n(rap)=9[/tex]

Number of dance songs, [tex]n(dance)=18[/tex]

Number of country songs, [tex]n(country)=12[/tex]

Formula for the probability of an event is [tex]P(e)=\frac{n(e)}{n(s)}[/tex]

Probability of playing a rock song, [tex]P(rock)=\frac{21}{60}[/tex]

⇒ [tex]\frac{7}{20}[/tex]

Probability of playing a rap song, [tex]P(rap)=\frac{9}{60}[/tex]

⇒ [tex]\frac{3}{20}[/tex]

Probability of playing a dance song, [tex]P(dance)=\frac{18}{60}[/tex]

⇒ [tex]\frac{9}{20}[/tex]

Probability of playing a country song, [tex]P(country)=\frac{12}{60}[/tex]

⇒ [tex]\frac{1}{5}[/tex]

Hence we can conclude that the probability of playing a rap song is 3/20.

Answers

Answer:

6x + 11x - 10

Step-by-step explanation:

So in order to solve this expression, we have to distribute the numbers in each set of parenthasis

Step 1 : break down each mini-espression you're solving

(2x+5)(3x-2)

each term is multiplied by both terms in the other set of parenthasis.

(2x · 3x) + (2x · -2) + (5 · 3x) + (5 · -2)

Step 2 : Solve each idividual piece

(2x · 3x) = 6x²

(2x · -2) = -4x

(5 · 3x) = 15x

(5 · -2) = -10

Step 3 : Put it all together amd simplify

6x² - 4x + 15x - 10

6x² + 11x - 10

What is 1 × 10 − 3 written in standard form? math

Answers

Answer:

7

Step-by-step explanation:

When working with order of operations, use the acronym 'PEMDAS' (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)

The equation should basically be done in that order.

There are no parenthesis,

no exponents,

But there IS multiplication.

1 x 10 = 10.

So now, what is left over is 10 - 3.

There addition, but there IS subtraction.

10 - 3 = 7.

7 is what is left over.

Therefore, 1 x 10 - 3 in standard form is 7.
