The total number of pieces of fruit that they bought should be 72.
The calculation is as follows:
Here we assume 3 bags of apples with 4 apples in each bag [tex](3 \times 4 = 12)[/tex]
And, 3 bunches of bananas with 4 bananas in each bunch [tex](3 \times 4 = 12)[/tex]
Now
= 12 + 12
= 24 pieces of fruit
Since
4 + 4 + 4 (12) apples + 4 = 4 + 4 (12) bananas
So,
= 12 + 12
= 24
here we need to multiplied by 3
So, [tex]= 24 \times 3[/tex]

A point $(x, y)$ with integer coordinates is randomly selected such that $0 \le x \le 8$ and $0 \le y \le 4$. what is the probability that $x + y \le 4$? express your answer as a common fraction.
Answer:
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
A point (x, y) with integer coordinates is randomly selected such that [tex]0 \le x \le 8 \:and\: $0 \le y \le 4$.[/tex]
The possible pairs of (x,y) are:
(0,0),(0,1),(0,2),(0,3),(0,4)
(1,0),(1,1),(1,2),(1,3),(1,4)
(2,0),(2,1),(2,2),(2,3),(2,4)
(3,0),(3,1),(3,2),(3,3),(3,4)
(4,0),(4,1),(4,2),(4,3),(4,4)
(5,0),(5,1),(5,2),(5,3),(5,4)
(6,0),(6,1),(6,2),(6,3),(6,4)
(7,0),(7,1),(7,2),(7,3),(7,4)
(8,0),(8,1),(8,2),(8,3),(8,4)
The Total Possible Outcomes n(S)= 45
The pair (x, y) that satisfies the given condition (say event A: [tex]x + y \le 4[/tex]) are:
[tex](0,0),(0,1),(0,2),(0,3),(0,4)\\(1,0),(1,1),(1,2),(1,3)\\(2,0),(2,1),(2,2)\\(3,0),(3,1)\\(4,0)[/tex]
n(A)=15
Therefore:
[tex]P(A)=\frac{n(A)}{n(S)} =\frac{15}{45} =\frac{1}{3}[/tex]
Final answer:
To find the probability that a randomly selected point with integer coordinates satisfies "x + y ≤ 4", we counted the number of qualifying points and divided by the total number of possible points. With 15 points meeting the condition out of 45 possible points, the probability is 1/3.
Explanation:
The probability question asks for the likelihood that a point (x, y) with integer coordinates will satisfy the condition "x + y ≤ 4" when 0 ≤ x ≤ 8 and 0 ≤ y ≤ 4. To solve this, we first count the total number of possible points with integer coordinates within the given ranges for x and y. Since x can take 9 values (0 through 8) and y can take 5 values (0 through 4), there are 45 possible points (9 times 5).
Next, we identify the points that satisfy the condition "x + y ≤ 4". These points are (0,0), (0,1), (0,2), (0,3), (0,4), (1,0), (1,1), (1,2), (1,3), (2,0), (2,1), (2,2), (3,0), (3,1), and (4,0), which results in a total of 15 points satisfying the condition.
The probability is therefore the number of satisfying points divided by the total number of possible points, which is 15/45 or simplified to 1/3. Thus, the probability that a randomly selected point with integer coordinates will have "x + y ≤ 4" is 1/3.
If a rectangle is 4 inches wide and 7 inches long. When the length and width are increased by the same amount, the area is increased by 26 square inches. What are the new dimensions.
Answer:
New length = [tex]2+7=9[/tex] inches
New width = [tex]2+4=6[/tex] inches
Step-by-step explanation:
Given:
Length of rectangle is 7 inches
Width of a rectangle is 4 inches
The area is increased by 26 square inches when the length and width are increased by the same amount.
To find: new length and width
Solution:
With length of rectangle is 7 inches and width of a rectangle is 4 inches,
area = 7×4 = 28 inches
Let length and width be increased by x inches
New length = x + 7 inches
New Width = x + 4 inches
New area = [tex](x+7)(x+4)=x^2 +11x+28[/tex]
Also, new area = 28 + 26 = 54 square inches.
So,
[tex]28+11x+x^2 =54\\x^2+11x-26=0\\x^2 +13x-2x-26=0\\x(x+13)-2(x+13)=0\\(x-2)(x+13)=0\\x= 2, -13[/tex]
As dimension can not be negative, [tex]x=-13[/tex] is rejected.
So, [tex]x=2[/tex]
New length = [tex]2+7=9[/tex] inches
New width = [tex]2+4=6[/tex] inches
Final answer:
The new dimensions of the rectangle are 6 inches by 9 inches, after increasing both the original width and length by 2 inches to achieve the new area of 54 square inches.
Explanation:
Solution to the Rectangle Problem
The original rectangle is 4 inches wide and 7 inches long, with an area of 28 square inches (since area = width imes length). When both the length and width are increased by the same amount, the area is 28 inches + 26 inches = 54 square inches. Let's denote the increase in dimension by 'x', thus the new dimensions are (4 + x) inches and (7 + x) inches. The new area is then (4 + x)(7 + x) = 54. Expanding this, we get 28 + 11x + x2 = 54. Simplifying, x2 + 11x - 26 = 0.
To find 'x', we can solve the quadratic equation. Factoring the quadratic, we get (x + 13)(x - 2) = 0, giving us two potential solutions for 'x': -13 and 2. However, since a negative increase in dimension is not possible, we only consider x = 2. Hence, the new dimensions of the rectangle are 6 inches by 9 inches.
Which describes the effect of the transformations on the graph of ƒ(x) = x2 when changed to ƒ(x) =1/2(x − 5)2 + 7?
A) stretched vertically, shifted left 5 units, and shifted down 7 units
B) stretched vertically, shifted right 5 units, and shifted up 7 units
C) compressed vertically, shifted left 5 units, and shifted down 7 units
D) compressed vertically, shifted right 5 units, and shifted up 7 units
The graph is stretched vertically, shifted left 5 units, shifted up 7 units.
We have to determine the effect of the transformations on the graph of ƒ(x) = x^2 when changed to ƒ(x) =1/2(x − 5)^2 + 7
What is the vertex form of the quadratic equation?The vertex form of the quadratic equation is f(x) = a(x-h)^2 + k.
ƒ(x) =1/2(x − 5)^2 + 7 compare with vertex form therefore we have
a=1/2,h=5 k=7.
a=1/2 means the closer to zero the a value, the wider, so this will stretch vertically.
h=5 and this means that the graph is shifted left 5 units.
k=7 this means that the graph is shifted up 7 units.
The answer is stretched vertically, shifted left 5 units, shifted up 7 units.

https://brainly.com/question/525947
Final answer:
The graph of f(x) = x^2 undergoes a vertical compression, horizontal shift to the right by 5 units, and a vertical shift up by 7 units to become f(x) = 1/2(x - 5)^2 + 7, corresponding to option B.
Explanation:
When comparing the original function f(x) = x^2 with the transformed function f(x) = 1/2(x − 5)^2 + 7, we can analyze the effects of transformation as follows:
Vertical Compression: The coefficient 1/2 in front of (x − 5)^2 causes a vertical compression by a factor of 1/2 compared to the original function.
Horizontal Shift: The term (x − 5) inside the function indicates a horizontal shift to the right by 5 units.
Vertical Shift: The constant +7 added outside the square indicates the graph is shifted up by 7 units.
Therefore, the correct description of the transformations applied to f(x) = x^2 to obtain f(x) = 1/2(x − 5)^2 + 7 is option B: compressed vertically, shifted right 5 units, and shifted up 7 units.

Of 58 cities, 3 have a lake and 23 have a river running through them. What fraction of these 58 cities have a lake or a river running through them?
Out of 58 cities, 26 have either a lake or a river, which simplifies to a fraction of 13/29 of the cities having one of these features.
Explanation:To find the fraction of 58 cities that have either a lake or a river running through them, we need to determine how many cities have at least one of these features. It is important to check if any city has both a lake and a river, but since the question does not provide this information, we will assume that there are no cities that have both. The question tells us that 3 cities have a lake and 23 have a river. We simply add these counts together to find the total number of cities with at least one water feature.
The calculation would be:
3 (cities with a lake) + 23 (cities with a river) = 26 (cities with a lake or a river)
To find the fraction of the 58 cities that have a lake or a river, we divide the number of cities with a water feature by the total number of cities:
26 (cities with a lake or a river) / 58 (total cities) = 13/29 (simplified fraction).
Final answer:
Of the 58 cities, 26 have either a lake or a river, which means the fraction of cities with a lake or a river is 26/58.
Explanation:
To determine what fraction of the 58 cities have a lake or a river running through them, we must consider that the question does not specify whether some cities might have both a lake and a river. Assuming that the cities with lakes and the cities with rivers do not overlap, we simply add the number of cities with each feature.
There are 3 cities with a lake and 23 with a river. To find the total number of cities with either a lake or a river, we add these two numbers together:
3 (cities with a lake) + 23 (cities with a river) = 26 (cities with a lake or a river).
Now, to find the fraction of the 58 cities that have a lake or a river, we divide the number of cities with water features by the total number of cities:
26 / 58 = fraction of cities with a lake or a river running through them.

Step-by-step explanation:
Eiko is wearing a magic ring that increases the power of her healing spell by 30% without the ring her healing spell restores H health points which expressions could represent how many health points the spell restores when eiko is wearing the magic ring
When wearing the magic ring, health points increase by 30% more.
Some expressions that could represent how many health points the spell restores are:
1.3(H)
H + 0.3(H)
Hope this helps!! :)
The healing spell with the magic ring restores 130% of the health points, represented as 1.30 imes H.
If Eiko's healing spell restores H health points without the magic ring, then with the ring, the spell's power increases by 30%. Thus, the total healing power with the ring can be expressed as H + 0.30 x H, which can also be simplified to 1.30 x H. This means, with the ring, Eiko would restore 130% of the health points that the spell would normally heal without the ring.

Papa Fred's Pizza has found that the menu time to deliver a pizza is 21.2 minutes with a
standard deviation of 6.1 minutes. They want to have a guaranteed delivery time. In order to
deliver 99% within the guaranteed time you need to find the time represented by the 99
percentile. What is this value?
Answer:
That time is 35.4 minutes.
Step-by-step explanation:
The mean time of delivery follows a Normal Distribution pattern.
So we need to apply Z-scores to find out.
99% confidence in delivery time means P(z > value) = 0.01 = 1%
So z > 2.325
so. Pr [ (x - 21.2) / 6.1 > 2.325 ] = 1%
so x > 2.325*6.1 + 21.2
x > 35.3825 minutes would be out of the 99th percentile
Final answer:
To calculate the 99th percentile of pizza delivery times, use the z-score corresponding to a 0.99 probability and apply the formula X = μ + (z * σ), where X represents the delivery time, μ is the mean, and σ is the standard deviation.
Explanation:
The student is asking for the 99th percentile of the pizza delivery time, given that the times are normally distributed with a mean of 21.2 minutes and a standard deviation of 6.1 minutes. To find the 99th percentile, one would typically use a z-score table or a statistical software to find the z-value that corresponds to the 0.99 probability. Once the z-score is found, the formula X = μ + (z * σ) is used to calculate the specific time that corresponds to the 99th percentile, where X is the delivery time, μ is the mean delivery time, σ is the standard deviation, and z is the z-score. Since the student is asking for a guaranteed delivery time that covers 99% of the deliveries, this time will be longer than the average to account for the variability represented by the standard deviation.

Answer:
5.83 or E
Step-by-step explanation:
Use Pythagorean theorem. 5^2+3^2=c^2 because the diameter is perpendicular it cuts the chord in half.
25+9=c^2
34=c^2
5.83
Answer:
x = 5.83.
Step-by-step explanation:
The diameter bisects the vertical chord so the right triangle has legs 3 and 5.
So x^2 = 3^2 + 5^2
x^2 = 34
x = 5.83.
That is odd - if we work it out another way we get a different answer. I guess that must be because the numbers given in the diagram are not possible.
If we use the intersecting chords theorem, we get (3+6)*3 = 27
= 5 * y where y is the other leg of the right triangle giving y = 5.4
and then this will give x = 6.18.
The polygons in each pair are similar. Find the missing side length.
Answer:
12
Step-by-step explanation:
If you flip the polygon on the right so it looks like the polygon on the left, the scale factor for the small polygon to the big polygon is 32/40 or 4/5.
Now use that scale factor, 4/5, to find the missing length
4/5 = ?/15
5*3 = 15 so 4*3 = ?
? = 12
The missing side of the given polygon is 12 units.
What is Polygon?
In geometry, a polygon is any closed curve made up of a collection of continuous line segments (sides) without any intersections. Triangles (three sides), quadrilaterals (four sides), and pentagons are the three simplest polygons (five sides).
If you flip the polygon on the right so it looks like the polygon on the left, the scale factor for the small polygon to the big polygon is 32/40 or 4/5.
Let x be the missing side of the polygon.
Now use that scale factor, 4/5, to find the missing length.
4/5 = x/15
5*3 = 15 so 4*3 = x
x = 12
therefore, 12 is the missing side of the given polygon.

The human eye can sharply see objects within a 15 Dagrees horizontal angle either side of the direction of focus. Arlo is designing a video presentation to be shown on a cylindrical screen that viewers will stand inside. The screen circumference is 120 feet. What is the maximum width of an image that can be viewed clearly in a glance from somewhere in the viewing area?
Answer:
Maximum width of image that can be viewed clearly on the cylindrical screen is 10 ft
Step-by-step explanation:
Here we have
Circumference of screen = 2πr = 120 ft
Angle that can be viewed horizontally either side of focus = 15°
Total angle view = 30°
Size of image that can be viewed = Object within 30° of focus
Maximum width of image that can be viewed clearly = Perimeter of 30° arc section of cylinder
Maximum width of image that can be viewed clearly = 30/360×120 ft = 10 ft.
Maximum width of image that can be viewed clearly on the cylindrical screen = 10 ft.

Answer: C, 120°
Step-by-step explanation:
If MATH is an isosceles Trapezoid, and the measurement of Angle A is 60°, then the Measurement of Angle M would be equivalent to the Measurement of Angle A. Then, using the Same Side Interior Theorem, the Measurement of Angle H would be equal to 180°- 60° (The Measurement of Angle M), which is equal to 120°, C.
