Answer:
The owner's prediction is Not Correct .. Based on the samples, about 35% of the books sold each week are fiction books.Step-by-step explanation:
The owner of a bookstore predicts that over 50% of the books she sells each week are fiction books.
Based on the table of randomly selected sample we see that in week 1 there are 50 fiction books out of total 150 books.
so, the percentage of fiction books are:
[tex]\dfrac{50}{150}\times 100\\\\=33.33\%[/tex]
Similarly in the second week i.e. week 2 the number of fiction books are 55 out of 150 books so, the percentage of fiction books in week 2 are:
[tex]\dfrac{55}{150}\times 100\\\\=36.66\%[/tex]
Hence,
The owner's prediction is Not Correct .. Based on the samples, about 35% of the books sold each week are fiction books.

The formula that relates the length of a ladder, L, that leans against a wall with distance d from the base of the wall and the height h that the ladder reaches up the wall is mc024-1.jpg. What height on the wall will a 15-foot ladder reach if it is placed 3.5 feet from the base of a wall? 11.5 feet 13.1 feet 14.6 feet 15.4 feet
Answers
Answer: 14.6 feet
Step-by-step explanation:
Since, here a ladder which has the length 15 foot and it is far from the base of the wall by 3.5 feet.
Here L represents the length of the ladder while d represents the distance of the ladder from the base of the wall. ( shown in figure)
While h represents height that the ladder reaches up the wall.
Thus, L= 15 foot, d= 3.5 foot
Then on applying Pythagoras theorem,
[tex]L^2=d^2+h^2[/tex]
⇒[tex]15^2=3.5^2+h^2[/tex]
⇒[tex]225=12.25+h^2[/tex]
⇒[tex]h^2=21.75[/tex]
⇒[tex]h=14.5859521458[/tex]≈ 14.6 foot
Thus,height that the ladder reaches up the wall= 14.6 foot ( approx)

Use elimination to solve the system of equations given by 3x + 4y = 5 and 21x + 28y = 35.
Answers
(0 = 0) is a true statement, it means that the system of equations has infinitely many solutions.
The correct option is (C).
To solve the system of equations using elimination, we'll manipulate one or both equations to eliminate one of the variables, either \(x\) or \(y\). Let's start by using elimination to eliminate \(x\).
Given the system of equations:
[tex]\[ \begin{cases} 3x + 4y = 5 \quad \quad \quad \quad \quad (1) \\21x + 28y = 35 \quad \quad \quad (2)\end{cases} \][/tex]
We can see that if we multiply equation (1) by 7, we can eliminate (x) when we add the equations together:
[tex]\[ 7(3x + 4y) = 7 \times 5 \][/tex]
[tex]\[ 21x + 28y = 35 \][/tex]
Now, we can rewrite equation (1) as:
[tex]\[ 21x + 28y = 35 \quad \quad \quad \quad \quad (3) \][/tex]
Now, we'll subtract equation (2) from equation (3):
[tex]\[ (21x + 28y) - (21x + 28y) = 35 - 35 \][/tex]
[ 0 = 0 ]
Since (0 = 0) is a true statement, it means that the system of equations has infinitely many solutions.
So, the correct answer is option C: Infinitely Many Solutions.

Laura bought a square canvas to paint a picture of her cat one side measured 22 centimeters what is tha area of the canvas
Answers
To start, squares are a shape in which all of its sides are congruent to one another. Knowing the length of one side would mean that you would know the length of all the other sides.
Because you know that one side measures 22 cm, you can conclude that all the other sides of the square are also at a length/width of 22 cm.
Next, you will find the area of the square.
Because the area formula is Area=Length * Width, you can easily find the area of the square by multiplying 22*22 since the length and width of any square is the same.
When you simplify 22*22, you should get 484.
Therefore, the area of the square canvas would be 484 cm squared.

The tank shown is made of steel. It does not have a cover. Find the area of steel sheet used to make the tank.
Answers
.. 2*(6.5 ft +28 ft) = 69 ft
so the lateral area of the tank is
.. 69 ft * 13 ft = 897 ft^2
The area of the bottom is
.. 6.5 ft * 28 ft = 182 ft^2
The total area is 897 ft^2 +182 ft^2 = 1079 ft^2.
then 6.5 * 13 * 2= 169 ft squared
and then find the last two sides which are
28 * 13= 364 ft squared
Finally you have to add all the above areas so, 182+169+364= 717 ft squared

Abigail flipped a coin 20 times, and it landed with heads facing up 13 times. What percent of the coin flips landed with heads facing up.
Answers
Divide:
13/20=0.65=65%
Hope this helped☺☺
The percentage of times Abigail's coin landed on heads is 65%, which is found by dividing the number of successful outcomes (head flips) by the total number of trials (total flips) and then multiplying by 100.
Explanation:The calculation you're asking for is one of percentage, which is a basic concept in mathematics often related to probability and statistics. We determine the percentage of times the coin landed on heads by dividing the number of successful outcomes (the coin landing on heads) by the total number of trials (the total coin flips), and then multiplying that result by 100 to convert the decimal to a percentage.
Here's a step-by-step way to do it:
Firstly, count the number of times the coin landed on heads, which is 13. Next, count the total number of coin flips, which is 20. Divide the number of successful outcomes (head flips) by the total trials (total flips). In this case, 13 ÷ 20 = 0.65. Finally, to convert this decimal to a percentage, multiply by 100. So, 0.65 × 100 = 65%.
So, 65% of Abigail's coin flips landed with heads facing up.

A circular garden has a circumference of 44 yards. Lars is digging a straight line along a diameter of the garden at a rate of 7 yards per hour. How many hours will it take him to dig across the garden?
Answers
plz give me the brainliest
It will take almost 2 hours to dig across the garden.
What is circumference of circle?"It is the length of the boundary of the circle."
Formula for the circumference of circle:[tex]c = 2\times \pi \times r[/tex]
What is rate?"It is the distance covered per unit times."
For given question,
A circular garden has a circumference of 44 yards.
⇒ C = 44
⇒ 2 × π × r = 44
⇒ 2 × r = 14.01 yards
We know, the diameter of the circle is d = 2 × r
This means, the diameter of the circular ground is 14.01 yards.
here, the rate (s) = 7 yards per hour
Using the formula of rate,
[tex]\Rightarrow s=\frac{d}{t}\\\\\Rightarrow 7=\frac{14.01}{t}\\\\ \Rightarrow t= 2.001\\\\ \Rightarrow t\approx 2~~hours[/tex]
Therefore, it will take him almost 2 hours to dig across the garden.
