There are 44 books per shelf and there are 8 shelves. 1/4 of these books are novels. How many novels will there be?

Answers

Answer 1

Answer: 88 Novels

Explanation:

Since there are 44 books per shelf and there are 8 shelves, we have a total of 44*8 or 352 books. Since only a quarter of them (1/4) are novels, we will multiply (1/4) and 352 together to get, 352*(1/4) equals 88 novels

Which best describes the graphs of the line that passes through (0,2) and (6,4) and the line that passes through (2,1) and (5,7)?

Answers

Answer:

The line which has slope 1/3 is a shallow line.

The line which has slope 2 is a steep line.

Both are increasing.

Step-by-step explanation:

Compare the lines by finding the slope between each pair of points.

Using the slope formula, substitute the points.

[tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{4-2}{6-0} = \frac{2}{6} = \frac{1}{3}[/tex]

[tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{7-1}{5-2} = \frac{6}{3} = 2[/tex]

The line which has slope 1/3 is a shallow line.

The line which has slope 2 is a steep line.

A group of students were asked whether they take French class, Art class, both classes or neither classes. The table shows the probabilities of the results

Art | Not Art | Total
French | 0.2 | 0.4 | 0.6
Not French | 0.35| 0.05 | 0.4
Total | 0.55 | 0.45 | 1.00

Let A represent taking French class and B represent taking Art class.

Which statement is true?

A. Taking Art class and taking French class are not independent events because P(A|B)=P(A) and P(B|A)=P(B) .

B. Taking Art class and taking French class are independent events because P(A|B)=P(A) and P(B|A)=P(B) .

C. Taking Art class and taking French class are independent events because P(A|B)≠P(A) and P(B|A)≠P(B) .

D. Taking Art class and taking French class are not independent events because P(A|B)≠P(A) and P(B|A)≠P(B) .<<<<<<<

Answers

Answer: D. Taking Art class and taking French class are not independent events because P(A|B)≠P(A) and P(B|A)≠P(B) .

Step-by-step explanation:

We know that for dependent events A and B , the conditional probability of getting a given that B is given by :-

[tex]P(A|B)=\dfrac{P(A\cap B)}{P(B)}[/tex]

From the given table, if A represent taking French class and B represent taking Art class.

Then P(A)=0.6

and P(B)=0.55

[tex]P(\cap B)=0.2[/tex]

Now, [tex]P(A|B)=\dfrac{0.2}{0.55}=0.036363\approx0.036[/tex]

[tex]P(B|A)=\dfrac{P(A\cap B)}{P(A)}=\dfrac{0.2}{0.6}=0.33333\aprox0.333[/tex]

Clearly, [tex]P(A|B)\neq P(A)[/tex]

[tex]P(B|A)\neq P(B)[/tex]

Therefore taking Art class and taking French class are not independent events because P(A|B)≠P(A) and P(B|A)≠P(B) .[ By definition of independent events]

The correct statement is D; Taking Art class and taking French class are not independent events.

Consider A represent taking a French class and B represents taking an Art class.

The formula to determine whether two events are independent or not is P(A and B) = P(A) x P(B),

where P(A and B) is the probability of both events happening together, P(A) is the probability of event A happening, and P(B) is the probability of event B happening.

D. Taking Art class and taking French class are not independent events because P(A|B)≠P(A) and P(B|A)≠P(B).

This statement is incorrect because the formula to determine whether two events are independent or not is;

P(A and B) = P(A) x P(B),

not P(A|B) ≠ P(A) and P(B|A) ≠ P(B).

Using the values in the table:

P(A) = 0.6 (taking French class)

P(B) = 0.55 (taking Art class)

P(A and B) = 0.2 (taking both classes)

P(A and B) ≠ P(A) x P(B)

0.2 ≠ 0.6 x 0.55

The correct statement is option D.

Describe a square using geometric vocabulary

Answers

Answer:

parallelogram with equal diagonals that bisect the angles

Step-by-step explanation:

A square is a geometric shape with four equal sides and four right angles. Its diagonals are equal and bisect each other at right angles. The perimeter is calculated as 4 times the side length, and the area is the side length squared.

A square is a fundamental geometric shape, characterized by several distinct properties:

A square has four equal sides, meaning each side has the same length.It has four right angles, with each angle measuring 90 degrees.The diagonals of a square are equal in length and bisect each other at right angles, dividing the square into four right-angled isosceles triangles.The perimeter of a square can be calculated as 4 times the length of one side (P = 4s).The area of a square can be calculated as the side length squared (A = s²).

For example, if each side of a square is 2 feet long,

area= 2 feet x 2 feet = 4 square feet.

These geometric properties make squares an important figure in mathematics and are often found in various structures and designs, emphasizing clarity and symmetry.

Solve −3.5 = x 4 for x using the multiplication property of equality.

Answers

Answer:

x = -14

Step-by-step explanation:

-3.5 = x/4

In the right side, the fraction x/4 means x divided by 4. We want x alone, so we multiply both sides by 4.

-3.5 * 4 = x/4 * 4

-14 = x

Answer: x = -14

The solution to the equation -3.5 = x/4for x using the multiplication property of equality is x = -14.

What is multiplication property of equality?

Multiplication property of equality is an equality property which states that if both the sides of an equation are multiplied by the same number, the expressions on the both sides of the equation are equal.

So,

-3.5 = x/4

multiply both sides by 4

-3.5 × 4 = x/4 × 4

-14 = x

Therefore, x equals negative 14.

A boat travels 60 miles downstream in the same time it takes to go 36 miles upstream the speed of the boat in Stillwater is 15 mph greater than the speed of the current find the speed of the current

Answers

Final answer:

To find the speed of the current, we can set up equations for the boat's downstream and upstream speeds and solve for the current speed.

Explanation:

To find the speed of the current, let's assume the speed of the boat in still water is x mph. Since the boat's speed downstream is 60 mph, we can set up the equation:

(x + c) * t = 60

Where 'c' represents the speed of the current, and 't' represents the time taken. Similarly, the equation for the upstream speed of the boat (36 mph) can be written as:

(x - c) * t = 36

Simplifying these equations, we get:

x + c = 60/t

x - c = 36/t

Adding these equations, we obtain:

2x = 96/t

Solving for x, we get:

x = 48/t

Substituting this value back into one of the original equations, we can solve for t:

(48/t) + c = 60/t

Simplifying, we find:

c = 12/t

Therefore, the speed of the current is inversely proportional to the time taken for the downstream and upstream journeys.

Final answer:

The spiciness of chili is determined by comparing the proportion of chili powder to tomato sauce. Jack consistently uses 222 teaspoons of chili powder per cup of sauce, whereas Marsha's ratio varies, but never exceeds 126.86 teaspoons per cup. Therefore, Jack's chili is spicier.

Explanation:

To determine whose chili is spicier, we must compare the ratio of chili powder to tomato sauce used by Jack and Marsha. Jack uses 222 teaspoons of chili powder for every 1 cup of tomato sauce. For Marsha, we'll have to establish the ratios based on her table.

When Marsha uses 444 teaspoons of chili powder, she uses 3.5 cups of tomato sauce. So, her ratio for this batch is 444/3.5 = 126.86 teaspoons of chili powder per cup of sauce.When Marsha uses 888 teaspoons her ratio is 888/7 = 126.86 teaspoons per cup.When she uses 1212 teaspoons, her ratio is 1212/10.5 = 115.43 teaspoons per cup.

Regardless of the quantity she makes, Marsha's ratio never goes below 115.43, which is less than Jack's ratio of 222. So, Jack's chili is spicier than Marsha's.

The Pythagorean theorem states that in a right-angled triangle, the sum of the squares of the two smaller sides is equal to the square of the hypotenuse.

The length of the diagonal can be found as follows:

A football field is rectangular in shape.

The diagonal of a rectangle divides it into two right-angled triangles.

Therefore, the diagonal becomes the hypotenuse of the right-angled triangles.

Therefore, diagonal² = length² + width²

diagonal² = 10,000 + 3600 yards²
