Answer:

6/12 (50%)

Step-by-step explanation:

If you roll greater than 3 you have a 3/6 chance of it, if you then roll a number less than 4 you have another 3/6 chance of it, therefore it should be 50% or 6/12

To find when the rocket will be at a certain height, we can set the equation for height, h(t), equal to the given height and solve for t.

For 24 meters:

-9.8t^2 + 36t = 24

-9.8t^2 + 36t - 24 = 0

We can solve for t using the quadratic formula:

t = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = -9.8, b = 36, and c = -24. Plugging in these values, we get:

t = (-36 ± sqrt(36^2 - 4(-9.8)(-24))) / 2(-9.8)

t ≈ 1.87 seconds or t ≈ 3.14 seconds

So the rocket will be at a height of 24 meters approximately 1.87 seconds after launch and again approximately 3.14 seconds after launch.

For 36 meters:

-9.8t^2 + 36t = 36

-9.8t^2 + 36t - 36 = 0

Using the quadratic formula again, we get:

t = (-36 ± sqrt(36^2 - 4(-9.8)(-36))) / 2(-9.8)

t ≈ 1.16 seconds or t ≈ 3.66 seconds

So the rocket will be at a height of 36 meters approximately 1.16 seconds after launch and again approximately 3.66 seconds after launch.

Answer:

The integer that describes the translation from B to B' is (-2,1)

Answer:

Step-by-step explanation:

Problem 1

The median weight of the Welsh corgis is 27 pounds. This is found in the table in row 1, column 2. Recall that the median is the middle most value, so that means 50% of the Welsh corgi weights will be less than 27 pounds, and also 50% of the weights are greater than 27 pounds.

========================================================

Problem 2

The Welsh corgis have the greater variation in weights. Why is this? There are two pieces of evidence:

The first of which is that the range for the first row (7) is larger than the range in the second row (2). The range is the difference between the max and min. The larger the range, the more spread out the data set will be.

The second piece of evidence is that the MAD (mean absolute deviation) for the Welsh corgis is larger compared to the MAD for the cocker spaniels group. The MAD is another way to measure the spread of a data set. Like the range, the larger the MAD gets, the more spread out the data is. It measures how far on average any given value is from the mean. It's similar to the standard deviation and variance, which are also measures of spread.

========================================================

Problem 3

Both dog breeds have the same mean value, and roughly the same median. Both the mean and median are measures of center. Based on just these two pieces of info alone, we could easily conclude that both dog groups have the same distribution more or less. Furthermore, we could conclude that both groups have roughly the same max weight value.

However, we discussed in problem 2 that the first group (Welsh corgi) is more spread out, so it's likely that could heavily imply that the min and max values are further from the center compared to the second group of dogs. Having a larger max would then mean that the corgi group has the largest weight.

In short, the answer is "Welsh corgi" due to this group having a greater spread, and that pushes the max further away from the center.

Answer:

Its c. c = 50.

Step-by-step explanation:

First, we need to figure out what the equation equals.

7 + 7/7 + 7*7 - 7 = x

PEMDAS

Parentheses, exponents, division/fraction, addition, subtraction.

7/7 = 1. So equation changed into 7 + 1 + 7*7 - 7 = x.

7*7 = 49. So equation changed again into 7 + 1 + 49 - 7.

Lets calculate it. 7 + 1 = 8 + 49 = 57 - 7 = 50. x = 50.

c is the only one who has a calculation of 50.

Answer:

No, because 1.875(25)-((25)+0.5(20))=11.875, which is less than 12.

Step-by-step explanation:

c = 25       d = 20

1.875(25) - (25+0.5*20) =

46.875 - 35 =

11.875

Answer:

:)

Step-by-step explanation:

a)

48 = d + 23

48 - 23 = d + 23 - 23

25 = d + 0

25 = d

b)

W - 13 = 28

W - 13  + 13 = 28 + 13

W + 0 = 41

W =  41

c)

\(9x = 72\\\\\frac{9x}{9} = \frac{72}{9}\\\\x = 8\)

d)

\(84 = 4n\\\\\frac{88}{4} = \frac{4n}{4}\\\\22 = n\)

Answer:

A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:

(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.

(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.

(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.

(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.

So, the pairings that always describe a function are:

(a person’s age in years, that same person’s height in inches)

(a person’s weight in pounds, that same person’s height in inches)

(a person’s height in centimeters, that same person’s height in inches)

These three pairings meet the criteria of a function, where each input corresponds to a unique output.

The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)

A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:

1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).

2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.

3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.

4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).

So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)

Let's say the test is 100 points.

The 70% mean means that the mean for the 30 students was 70 points.  That means 2100 points were scored between all 30 students. (70·30=2100)

20 boys had a mean of 62% or 62 points for our test.  That means the boys earned 62·20 points, or 1240 points.

That then means the girls earned 2100 - 1240 points, or 860 points.

Since there are 10 girls, 860/10 = 86 or 86% mean on the test.

Answer:

D (Alicia did 5 more jumping jacks per minute than Melissa.)

Step-by-step explanation:

Alicia's rate is 30 jumping jacks per minute. You can use the formula m=(y2-y1)/(x2-x1) to find the slope/rate. The two points in the table you can use are (1,30) and (2,60). You can plug those coordinates into the slope formula. (60-30)/(2-1)=30/1= 30 jumping jacks per minute.  To find the rate of change/slope for Melissa, you can use the same formula m=(y2-y1)/(x2-x1). The two points you could plug in are (0,0), and (4,100). (100-0)/(4-0)=100/4=25. Melissa does 25 jumping jacks per minute.

#SPJ1

Answer:

Step-by-step explanation:

To find the conditional frequency of someone who likes Flip-Frog game and is between 18 and 22 years old, we need to use the formula:

Conditional frequency = (Frequency of Flip-Frog players between 18 and 22) / (Total frequency of Flip-Frog players)

From the table, we see that the frequency of Flip-Frog players between 18 and 22 is 4, and the total frequency of Flip-Frog players is 9+4+12=25.

Therefore, the conditional frequency of someone who likes Flip-Frog game and is between 18 and 22 years old is:

Conditional frequency = 4 / 25 = 0.16 = 16%

Rounding to the nearest tenth, we get:

Conditional frequency = 16.0%

So, the answer is not one of the options given.
