The probability of getting exactly 9 of them major in STEM is 0.139 or 13.9%.

The probability of getting at most 11 of them major in STEM is approximately 0.898 or 89.8%.

The probability of getting at least 11 of them major in STEM is approximately 0.318 or 31.8%.

a. Exactly 9 of them major in STEM.

In this case, the probability of success (a student majoring in STEM) is 0.27, and the number of trials is 35. The probability of exactly 9 students majoring in STEM is then given by the formula:

P(X = 9) = (35 choose 9) x (0.27)⁹ x (0.73)²⁶

where (35 choose 9) is the number of ways to choose 9 students out of 35, and (0.27)⁹ x (0.73)²⁶ is the probability of 9 successes and 26 failures. Evaluating this expression gives a probability of approximately 0.139 or 13.9%.

b. At most 11 of them major in STEM.

To calculate the probability that at most 11 students out of 35 major in STEM, we can use the cumulative binomial probability distribution. This distribution calculates the probability of at most X successes, where X is any number from 0 to the total number of trials.

The probability of at most 11 students majoring in STEM can be calculated as follows:

P(X <= 11) = P(X = 0) + P(X = 1) + ... + P(X = 11) = 0.898 or 89.8%.

c. At least 11 of them major in STEM.

The probability of less than 11 students majoring in STEM can be calculated using the cumulative binomial probability distribution, as in part (b). Specifically:

P(X < 11) = P(X = 0) + P(X = 1) + ... + P(X = 10)

Subtracting this probability from 1 gives the probability of at least 11 students majoring in STEM:

P(X >= 11) = 1 - P(X < 11) = 31.8%

Again, we can use the binomial distribution formula from part (a), or a binomial probability calculator or statistical software package to calculate this probability.

Answer:

Step-by-step explanation:

Let's just say this circle has value x.

x increases by 5%, or 0.05 of x.

x + 0.05x = 1.05x

1.05x now increases by 5% again:

1.05x + 0.05(1.05x) = 1.1025x

The total increase is equal to (1.1025-1)*100 = 10.25%

Answer:

  A:  (b) 320 is what percent of 400

  B:  80%

Step-by-step explanation:

Part A:

This is a reading comprehension question. You are told that ...

  $320 is the amount needed

  $400 is the amount earned

and you are asked to find ...

  what percent of the amount earned is the amount needed?

The question can be rephrased as ...

  the amount needed is what percent of the amount earned?

Filling in the amounts you are told, the rephrased question becomes ...

  $320 is what percent of $400 . . . . . matches choice (b)

__

Part B:

If we let x represent "what percent", then we can write the above question as ...

  320 = x · 400

Dividing by 400 gives ...

  320/400 = x = 0.80 = 80%

That is, 320 is 80% of 400.

If \(a = 0\), then \(y = ax^2+bx+c\) turns into \(y = 0x^2+bx+c\). That \(0x^2\) term goes away because it turns into 0, and adding 0 onto anything does not change the expression.

So  \(y = 0x^2+bx+c\) turns into \(y = bx+c\) which is a linear equation (b is the slope, c is the y intercept). It is no longer a quadratic as quadratic equations always graph out a curved parabola.

As an example, you could graph out \(y = 0x^2+3x+4\) and note how it's the exact same as \(y = 3x+4\), both of which are straight lines through the two points (0,4) and (1,7).

Answer:

√38

Step-by-step explanation:

√38

step 1: Check which squared numbers can be multiplied by another number to get 38.

Start with these numbers: 4, 9, 16, and 25

Step 2: Testing out the numbers

√25 × __ = 25 can't be divided by 38

√16 × ___ = 16 can't be divided by 38

√9 × ____ = 9 can't be divided by 38

√4 × ____= 4 can't be divided by 38

Step 3: Answer

After trying the square root numbers that could possibly work with √38 none work; which means √38 can't be simplified. So the answer is √38

THIS IS THE COMPLETE QUESTION BELOW;

In Littletown, the probability that a baseball team goes to the city playoffs is 0.30. the probability that the team goes to the state playoffs given that the team goes to the city playoffs is 0.20.

What is the probability that a randomly selected team from Littletown goes to the city and state playoffs?

A. 0.10

B.0.50

C. 0.66

D. 0.06

Answer:

OPTION D is correct

d)0.06

the probability that a randomly selected team from Littletown goes to the city and state playoffs is \(0.06\)

Step-by-step explanation:

The probability that a baseball team goes to city playoffs is 0.30.

P(baseball team goes to city playoffs)=0.30

The probability that the team goes to state playoffs given that the team goes to the city playoffs is 0.20.

P(team goes to state playoffs given that the team goes to the city playoffs)=0.20

From our knowledge of set, we know that

P(A | B)= P(A ∩ C)/P(C)

where A= city playoffs

B= state playoffs

P(State play off | city play off)=0.20

P(State play off ∩ city play off)/P(city play off,)=0.20

P(State play off ∩ city play off)/0.30 =0.20

P(State play off ∩ city play off)= 0.30 × 0.20

= 0.06

Hence,the probability that a randomly selected team from Littletown goes to the city and state playoffs is 0.06

Answer:

  y =  {-180, 2 8/11}

Step-by-step explanation:

I like to solve these using a graphing calculator. I generally start by writing the equation in the form ...

  f(y) = 0

This can be done by subtracting the right-side expression from both sides. The solution will be the horizontal intercepts of the graph:

  y = -180; y = 2 8/11

__

To solve this analytically, you need to recognize that this resolves into four equations, effectively two identical pairs. Each equation comes with a set of conditions (domain) for which it is applicable. Here is the expanded set of equations:

  1/3y -7 = 2/5y +5 . . . both positive: 1/3y -7 ≥ 0 and 2/5y + 5 ≥ 0

  7 -1/3y = 2/5y +5 . . . left side negative: 1/3y -7 ≤ 0 and 2/5y +5 ≥ 0

  1/3y -7 = -2/5y -5 . . . right side negative: 1/3y -7 ≥ 0 and 2/5y +5 ≤ 0

  7 -1/3y = -2/5y -5 . . . both sides negative: 1/3y -7 ≤ 0 and 2/5y +5 ≤ 0

__

The conditions resolve to ...

  1/3y -7 ≥ 0

  y -21 ≥ 0 . . . . . multiply by 3

  y ≥ 21 . . . . . . . add 21

and ...

  2/5y +5 ≥ 0

  y +25/2 ≥ 0 . . . . multiply by 5/2

  y ≥ -25/2 . . . . . subtract 25/2

Now, we are in a position to solve the equations and determine where the solution is applicable.

__

both positive

The domain will be y ≥ 21 and y ≥ -25/2, which is y ≥ 21.

Multiplying the equation by 15 gives ...

  5y -105 = 6y +75

  y = -180 . . . . . . . . . subtract 5y+75

This solution is not in the allowed domain.

__

left side negative

The domain will be y ≤ 21 and y ≥ -25/2, which is -25/2 ≤ y ≤ 21.

Multiplying the equation by 15 gives ...

  105 -5y = 6y +75

  30 = 11y . . . . . . . . . add y-75

  y = 30/11 . . . . . .  the solution is in the allowed domain

__

right side negative

The domain will be y ≥ 21 and y ≤ -25/2. This is the empty set.

__

both sides negative

The domain will be y ≤ 21 and y ≤ -25/2, which is y ≤ -25/2.

Multiplying the equation by 15 gives ...

  105 -5y = -6y -75

  y = -180 . . . . . . . . . . add 6y-105 . . . . the solution is in the allowed domain

__

Solutions to this equation are ...

  y = 30/11 = 2 8/11

  y = -180

Answer:

The circumference of a circle is given by the formula "C = pi x d" where "d" is the diameter and "pi" is the mathematical constant with an approximate value of 3.14.

In this problem, the diameter of the bicycle wheel is 60 centimeters, so its circumference is:

C = pi x d = 3.14 x 60 = 188.4 centimeters

When the wheel makes one revolution, it travels one circumference distance. Therefore, when the wheel makes 35 revolutions, it will travel:

distance = 35 x circumference = 35 x 188.4 = 6584 centimeters

We can convert centimeters to meters by dividing the distance by 100:

distance = 6584 ÷ 100 = 65.84 meters

Therefore, the wheel travels 65.84 meters when it makes 35 revolutions.

The mean absolute deviation (MAD) for the given data is 1/20. This means that, on average, each data point in the set differs from the mean by 1/20.

To find the mean absolute deviation (MAD) of a set of data, we need to calculate the average difference between each data point and the mean of the data set. Here's how we can calculate it for the given data:

Step 1: Find the mean (average) of the data set.

Mean = (1/4 + 5/8 + 3/8 + 3/4 + 1/2) / 5 = 2/5

Step 2: Calculate the difference between each data point and the mean.

Differences: |1/4 - 2/5|, |5/8 - 2/5|, |3/8 - 2/5|, |3/4 - 2/5|, |1/2 - 2/5|

Step 3: Calculate the absolute value of each difference.

Absolute Differences: 1/20, 1/40, 1/40, 1/20, 1/10

Step 4: Find the average of the absolute differences.

MAD = (1/20 + 1/40 + 1/40 + 1/20 + 1/10) / 5 = 1/20

The MAD provides a measure of the average amount of variation or dispersion in the data set. In this case, a MAD of 1/20 indicates that the data points are relatively close to the mean, with most values falling within 1/20 of the mean value.

2.2.1 Answer: Three other angles equal to x are:

Angle QRP: Since RQ = RT, triangle RQT is an isosceles triangle and angle QRP is equal to angle TRQ (x) by the Isosceles Triangle Theorem.

Angle QPR: Since TR is a tangent to the circle at R and OR is a radius, angle TRQ (x) is equal to angle QPR by the Alternate Segment Theorem.

Angle QPO: Since TQP is a straight line, angle QPO is supplementary to angle QPR and therefore also equal to x.

2.2.2 Answer: If x = 75°, then angle QRP = 75° and angle QPR = 75°. Since TQP is a straight line, angle QPO = 180° - 75° = 105°. In order for PTRO to be a cyclic quadrilateral, opposite angles must add up to 180°. However, angle TRO + angle TPO = 75° + 105° = 180° ≠ 180°. Therefore, PTRO is not a cyclic quadrilateral.
