the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answers
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Find the surface area of the square pyramid shown. Label the net to help you.
I have to show work
Answers
Answer: 40 inches squared
Labels are in the pictures
Step-by-step explanation:
To find the surface area, find the area of each side.
Square (base) : side * side = 4*4 = 16
Triangle (sides) : (base * height)/2
Assuming each side is a isosceles triangle, the base 4/2 = 2
(2*6)/2 = 12/2 = 6
Since there are 4 triangles, we can multiply 6 by 4 to get the combined area. We then add the area of the square to get the final result.
6*4 + 16 = 24+16 = 40

A box contains several copies of Mrs. Spencer's new pamphlet. The box weighs 2,000 grams. This chart shows the effect of adding or taking away a pamphlet. Pamphlets Added to the box(x) Effect on the Box's Weight (y) 0 0 1 6 2 12 3 18 Is this an example of continuous or discrete data? discrete continuous
Answers
Answer:
This example represents discrete data.
Step-by-step explanation:
Discrete data refers to information that can only take certain specific values. In this case, the number of pamphlets added to the box (x) can only take on integer values such as 0, 1, 2, 3. Similarly, the effect on the box's weight (y) is also given as specific values: 0, 6, 12, 18.
In contrast, continuous data would involve measurements that can take any value within a range, such as height, weight, or temperature.
Since the number of pamphlets added and the corresponding effect on the box's weight are presented as specific, separate values, the data in this example is considered discrete.
Consider the infinite geometric series infinity sigma n=1 -4(2/3)^n-1. In this, the lower limit of the summation notion is "n=1". PLEASE show your work I dont understand
1)write the first four terms of the series 2) does the series diverge or coverge 3) if the series has a sum find the sum
Answers
Answer:
To find the first four terms of the series, we can substitute the values of n from 1 to 4 in the given formula and simplify:
n=1: -4(2/3)^0 = -4(1) = -4
n=2: -4(2/3)^1 = -4(2/3) = -8/3
n=3: -4(2/3)^2 = -4(4/9) = -16/9
n=4: -4(2/3)^3 = -4(8/27) = -32/27
So the first four terms of the series are -4, -8/3, -16/9, -32/27.
To determine if the series converges or diverges, we need to find the common ratio r, which is the ratio of any term to its preceding term:
r = (-4(2/3)^n) / (-4(2/3)^(n-1)) = 2/3
Since the absolute value of the common ratio is less than 1, the series converges.
To find the sum of the series, we can use the formula for the sum of an infinite geometric series:
S = a / (1 - r)
where a is the first term and r is the common ratio. Substituting the values we found:
S = -4 / (1 - 2/3) = -4 / (1/3) = -12
So the sum of the infinite geometric series is -12.
Answer:
a) The first four terms of the series are:
-4, -8/3, -16/9, -32/27
b) The series converges.
c) The sum of the infinite geometric series is -12.
Step-by-step explanation:
Given infinite geometric series:
\(\displaystyle \sum^{\infty}_{n=1} -4 \left(\dfrac{2}{3}\right)^{n-1}\)
Therefore, the formula for the nth term of the sequence is:
\(a_n=-4 \left(\dfrac{2}{3}\right)^{n-1}\)
where:
-4 is the first term, a.2/3 is the common ratio, r.Calculate the first four terms of the series by substituting the n-values 1 through 4 into the nth term formula.
\(a_1 = -4 \left(\dfrac{2}{3}\right)^{1-1} = -4 \left(\dfrac{2}{3}\right)^{0}=-4\)
\(a_2 = -4 \left(\dfrac{2}{3}\right)^{2-1}= -4 \left(\dfrac{2}{3}\right)^{1}=-\dfrac{8}{3}\)
\(a_3 = -4 \left(\dfrac{2}{3}\right)^{3-1}= -4 \left(\dfrac{2}{3}\right)^{2}=-4 \left(\dfrac{4}{9}\right)=-\dfrac{16}{9}\)
\(a_4 = -4 \left(\dfrac{2}{3}\right)^{4-1}= -4 \left(\dfrac{2}{3}\right)^{3}= -4 \left(\dfrac{8}{27}\right)=-\dfrac{32}{27}\)
A geometric series converges if the absolute value of its common ratio is less than 1. As r = 2/3 and |2/3| < 1, the series converges.
Use the infinite geometric series sum formula to find sum of the infinite series.
\(\boxed{\begin{minipage}{5.5 cm}\underline{Sum of an infinite geometric series}\\\\$S_{\infty}=\dfrac{a}{1-r}$,\;\;for\;$|r| < 1$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the first term. \\ \phantom{ww}$\bullet$ $r$ is the common ratio.\\\end{minipage}}\)
Substitute a = -4 and r = 2/3 into the formula to find the sum of the infinite series:
\(\begin{aligned}\implies S_{\infty}&=\dfrac{-4}{1-\frac{2}{3}}\\\\ &=\dfrac{-4}{\frac{1}{3}}\\\\&=-4 \cdot \dfrac{3}{1}\\\\&=-\dfrac{12}{1}\\\\&=-12\end{aligned}\)
Therefore, the sum of the given infinite geometric series is -12.

Jason wants to plant 66 carrot seeds and 44 onion bulbs. He would like to plant them so
that there are the same number of plants in each row and each row only has one type of plant. a. What is the greatest number of plants he can have in each row? SHOW YOUR
WORK
Answers
Answer:
Step-by-step explanation:
Since we need an equal amount plants in each row, you have to find the greatest common factor (GCF) of 66 and 44.
The factors of 44 are: 1, 2, 4, 11, 22, 44
The factors of 66 are: 1, 2, 3, 6, 11, 22, 33, 66
Therefore, the greatest factor of 66 and 44 is 22. This means Jason will have 3 rows of carrot plants and 2 rows of onion plants. Each row will have 22 plants.
Jason can have a maximum of 22 plants in each row. This allows him to place 22 onion bulbs or 22 carrot seeds in each row.
We need to determine the greatest common divisor (GCD) of 66 and 44 to determine the maximum number of plants Jason can have in each row while still adhering to the requirements of having the same number of plants in each row and each row having only one type of plant.
The GCD denotes the maximum number of plants he is permitted to place in each row.
Using the Euclidean algorithm to find the GCD:
1. Divide the larger number by the smaller number:
66 ÷ 44 = 1 with a remainder of 22.
2. Divide the smaller number 44 by the remainder 22: 44 ÷ 22 = 2 with no remainder.
3. Since there is no remainder, the GCD is the divisor in the last division, which is 22.

For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).
Range: The range is the difference between the largest and smallest values in the dataset.
For Mountain View School:
Range: 9 - 0 = 9
For Seaside School:
Range: 9 - 0 = 9
Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.
For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4
For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5
To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.
Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice
For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.
For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.
Part B:
For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.
For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.
Part C:
If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

Too cold to grow certain crops and the increased droughts could reduce the amount of water available for irrigation are the correct option.
What is climate change?It is defined as the change in weather and atmosphere temperature that happens after a very long time run. The main reason for climate change is the burning of fossils fuel or coal, and the wood resulting increase in carbon-di-oxide.
Climate change leads to affect the agriculture in many different ways such as:
As the temperature increases in the atmosphere the water level on the land decreases resulting in less water available for agriculture.Increased droughts affect the crop and reduce the amount of water for irrigation.Increase in precipitation affects the crop.If the temperature is too low and there is no sunlight it will be hard to grow the crops.Whenever the climate changes new types of pests and insects evolved which will lead to affect agriculture.Thus, too cold to grow certain crops and the increased droughts could reduce the amount of water available for irrigation are the correct option.
