The weight of the heaviest 18% of fruits is 371.7 grams, and we can use deviation and the normal distribution curve to find this answer.

To answer this question, we need to use the concept of deviation and the normal distribution curve. We know that the mean weight of the fruit is 346 grams, and the standard deviation is 30 grams.

Since we want to find out the weight of the heaviest 18% of fruits, we need to look at the right side of the normal distribution curve. We know that 50% of the fruits will be below the mean weight of 346 grams, and 50% will be above it.

We can use a Z-score table to find out the Z-score corresponding to the 82nd percentile (100% - 18%). The Z-score is 0.89.

Now we can use the formula Z = (X - mean) / standard deviation to find out the weight of the heaviest 18% of fruits. Rearranging the formula, we get X = (Z * standard deviation) + mean.

Plugging in the values, we get X = (0.89 * 30) + 346 = 371.7 grams. Rounded to the nearest gram, the heaviest 18% of fruits weigh more than 372 grams.

In conclusion, the weight of the heaviest 18% of fruits is 371.7 grams, and we can use deviation and the normal distribution curve to find this answer.

The speed of object is 3.68m\s.

Given that,

Mass of the object =  5.2 kg,

Object that possesses 26.1 J of kinetic energy.

We have to find,

The speed of the object.

According to the question,

Kinetic energy is a form of energy that an object or a particle has by reason of its motion.

If work, which transfers energy, is done on an object by applying a net force, the object speeds up and there by gains kinetic energy.

Then, The formula of kinetic energy is given as,

\(K.E = \frac{1}{2} mv^{2}\)

Where, m = mass of the object

And v = speed of the object

Therefore, The speed of the object calculated as.

\(KE = \frac{1}{2} mv^{2} \\\\26.1 = \frac{1}{2} \times 5.2\times v^{2} \\\\26.1 = 2.6 \times v^{2} \\\\\frac{26.1}{2.6} = v^{2} \\\\v^{2} = 10.1\\\\v = \sqrt{10.1} \\\\v = 3.68\)

Hence, The speed of object is 3.68m\s.

Answer:

im pretty sure it would be -8-(-6)=-2 for the first one

Answer:

- 4

Step-by-step explanation:

2x + 5 = - 3 ( subtract 5 from both sides )

2x = - 8 ( divide both sides by 2 )

x = - 4

then the number from the set which is the solution to the equation is - 4

Answer:

I believe the answer for the first one is -3, 3, number 3 would be 12

Step-by-step explanation:

Because if you are dilating by 1/3 then you will be dividing by 3, so if your point A coordinates are -9,9 then that divided by 3 is -3,3

Number 3 is 12 because your total of units from point D to C is 18 and it says to dilate by scale factor of 2/3 which again means to divide by 2/3 making your new length 12 units.

Answer:

y = 1/2x + 2

Step-by-step explanation:

The y-intercept is 2 because it passes through the y axis at (0,2) and the slope if 1/2

Hope that helps and have a great day!

Answer:

\(y=\frac{1}{2}x+2\)

Step-by-step explanation:

To find the equation for the line, lets try to find the slope and y-intercept of the line.

From looking at the graph, we can see that the line intersects the y-axis at y = 2. So the y-intercept would be 2.

The slope of the line would be the rise divided by the run. Looking at the graph, we can see that for every 2 the line moves in the x-direction, it moves 1 in the y-direction. This means that the rise is 1 and the run is 2. So the slope would be 1/2.

So we now know that the slope is 1/2 and the y-intercept is 2, we can now plug the information into the slope-intercept form.

Slope-intercept form is:

y = mx + b

where m is the slope and b is the y-intercept.

Plugging in we get

\(y=\frac{1}{2}x+2\)

And now we have the equation of the line.

The total amount of lemonade Regan sells is 69/16 gallons and this can be determined by using the arithmetic operations.

Given :

   Mark sold 2 7/8 gallons of lemonade.

   Regan sold 2/3 as much lemonade as Mark.

The following steps can be used in order to determine the total amount of lemonade Regan sells:

Step 1 - The arithmetic operations can be used in order to determine the total amount of lemonade Regan sells.

Step 2 - According to the given data, Mark sold 23/8 gallons of lemonade.

Step 3 - Let the total amount of lemonade Regan sells be 'x'.

Step 4 - So, the value of 'x' can be calculated as:

x = 23/8 × 3/2

x = 63/16

The total amount of lemonade Regan sells is 69/16 gallons.

The probabilities are given as follows:

A probability is calculated as the division of the desired number of outcomes by the total number of outcomes.

We have 10 numbers, out of which 7 are multiples of 10, hence the probability of drawing two multiples of 10 is of:

7/10 x 6/9 = 42/90 = 21/45.

(for the second number there are only 9 options, hence the division by 9).

The probability of getting a number less than 100 for both draws is of:

5/10 x 4/9 = 2/9.

The expressions that represent how many strawberries Jill needs for all the smoothies are 4x, 5x, and 6x. Each expression represents the number of strawberries required per smoothie multiplied by the number of friends Jill has.

Jill is experimenting with three different strawberry smoothie recipes. The first recipe uses 4 strawberries per smoothie, the second recipe uses 5 strawberries per smoothie, and the third recipe uses 6 strawberries per smoothie. To calculate the total number of strawberries Jill needs for all the smoothies, we need to multiply the number of strawberries per smoothie by the number of friends Jill has.

Since Jill has x friends, the expression 4x represents the total number of strawberries needed for all the smoothies using the first recipe. Similarly, the expression 5x represents the total number of strawberries needed for all the smoothies using the second recipe, and 6x represents the total number of strawberries needed for all the smoothies using the third recipe. Each expression accounts for the number of smoothies made per friend (x) multiplied by the number of strawberries per smoothie.

The provided function's definite integral from 0 to 10 is closest to 4.

The area of each zone that the function, the x-axis, and the two vertical lines at x = 0 and x = 10 bounds is added to form the definite integral of the function. The definite integral that results from adding up each of these areas is the one that is closest to 4. The area of the region above the x-axis is larger than the area of the region below the x-axis, which explains this. The area of the region above the x-axis is higher than the area below the x-axis because the function is rising across the interval. The overall area is closer to 4 since the area of the region below the x-axis is negative. As a result, 4 is the closest value for the definite integral of the 0–10 function.

Answer:

Step-by-step explanation:

To find the slope, you need to find the y-intercept first (or the place the line crosses over the y-line). After you've found the y-intercept (-1), you need to find the next point that the line crosses. This line has a positive slope, so you'll want to look for the next point towards the right. The next point was 1 up and 2 over.

Answer:

y = 2/5x - 1

Step-by-step explanation:

There are a couple of different ways to figure this out, but since you have a graph, the fastest way is to count the slope, or m in the formula, by counting the rise (units up) over run (units to the right), which is 2/5. Then, find the value of b by finding the y-intercept on the graph, or -1.

The correlation coefficient of 0.90 indicates a strong positive linear correlation between happiness and GPA of high school students.

A correlation coefficient measures the strength and direction of the relationship between two variables. In this case, the correlation coefficient of 0.90 indicates a strong positive linear correlation between happiness and GPA of high school students.

A positive correlation means that as one variable (in this case, happiness) increases, the other variable (GPA) also tends to increase. The magnitude of the correlation coefficient, which ranges from -1 to 1, represents the strength of the relationship. A value of 0.90 indicates a very strong positive linear correlation, suggesting that there is a consistent and significant relationship between happiness and GPA.

This means that as the level of happiness increases among high school students, their GPA tends to be higher as well. The correlation coefficient of 0.90 suggests a high degree of predictability in the relationship between these two variables.

It is important to note that correlation does not imply causation. While a strong positive correlation indicates a relationship between happiness and GPA, it does not necessarily mean that one variable causes the other. Other factors or variables may also influence the relationship between happiness and GPA.

145 balls would fit inside the bin.

Given:

The radius of the ball (r) = 16 cm

The height of the ball bin  = 210 cm

The opening at the top is a square that is 150 cm × 150 cm.

The side length of the square ball bin = 150 cm

To Find:

How many balls should fit inside the bin = ?

First we find the volume of the ball.

Let the volume of the ball be V1

The volume of the sphere = 4/3 × π × r³

Substituting the value,

⇒ V1 = 4/3 × π × 16³

⇒ V1 = 4/3 × π × 4096

⇒ V1 = (16348 × π) / 3

⇒ V1 = 17157.3 cubic centimeters

Now, we find the packing space per ball

= 190 percent of volume of one ball

= 190% of 17157.3

= 190/100 × 17157.3

= 1.9 × 17157.3

= 32598.9 cubic cm

Now, we find the volume of the container

The volume of the square prism (packing box )

= base area × height

= area of square × height

= 150² × 210

= 4725000 cubic centimeters

Now, we find the number of ball that can fit in the container

Number of ball = volume of the container / the packing space per ball

so,

⇒ Number of ball = 4725000 /  32598.9

⇒ Number of ball = 144.9

⇒ Number of ball ≈ 145

This means, approximately 145 balls should fit inside the bin.

Therefore, 145 balls would fit inside the bin.
