To meet the goal, the company should adjust the mean and/or standard deviation so that the probability of cans having a volume less than 355ml is less than 2.5%.

A probability is a numerical representation of the likelihood or chance that a specific event will take place.

We can use the z-score formula to find the probability of cans having a volume less than 355 ml.

z-score = (355 - 358.2) / 1.8 = -1.78

Probability of cans having a volume less than 355ml = P(z < -1.78) = 0.0372

The company is not meeting its goal since the probability of cans having a volume less than 355ml is 0.0372 which is greater than 2.5%.

Two numbers are in the ratio 8cm:1m, he greater number is 3,125.

A ratio in mathematics demonstrates how many times one number is present in another. A ratio can have any number of quantities, such as counts of people or things or measurements of length, weight, time, etc. Both numbers must be positive in most situations. An ordered pair of integers, a fraction with the first number in the numerator and the second in the denominator, or the value represented by this fraction are all examples of ratios.

Given that, Two numbers are in the ratio 8cm:1m and smaller number is 250.

let the greater number is x.

ratio = 8cm/1m

= 8cm/100cm

= 1/12.5 or 1:12.5

1/12.5 = 250/x

⇒ x = 250 * 12.5

⇒ x = 3,125

So, the greater number is 3,125.

The mean decreases by 2.9°. Therefore, option D is the correct answer.

In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.

Given that, the average high temperatures in degrees for a city are 58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57.

Here, average = Sum of all the observations/Number of observations

= (58+61+71+77+91+100+105+102+95+82+66+57)/12

= 965/12

New average = 965+42.5/12+1

The quadratic equation to find the width of the rectangle by formulating the area and length value is 2w² - w - 91 = 0.

What is area?

An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.

The value for the area of the rectangle is given as = 91 in²

Let the width for the rectangle be = w

Then the length of the rectangle is 1 less than twice its width, l = (2w - 1)

The formula for the area of the rectangle is -

Area = length × width

Substitute the values to get the equation for width -

91 = (2w - 1) × w

Use the arithmetic operation of multiplication -

91 = w(2w - 1)

91 = 2w² - w

Rearrange in quadratic form -

2w² - w - 91 = 0

Therefore, the equation is obtained as 2w² - w - 91 = 0.

The coordinates of the image of the parallelogram are:

There are two ways of reflection.

Along x-axis:

(x, y) – (x, -y)

Along y-axis:

We have,

Parallelogram CDEF with vertices:

C = (-4, -4)

D = (-2, 0)

E = (6, 1)

F = (4, -3)

The parallelogram is reflected over the line y = 2.

This means,

The y-coordinates will change and the x-coordinate will remain the same.

Now,

C = (-4, -4)

There are 6 units between y = 2 and y = -4 so,

C' = (-4, 2 + 6) = (-4, 8)

D = (-2, 0)

There are 2 units between y = 2 and y = 0 so,

D' = (-2, 2 + 2) = (-2, 4)

E = (6, 1)

There are 1 units between y = 2 and y = 1 so,

E' = (6, 2 + 1) = (6, 3)

F = (4, -3)

There are 5 units between y = 2 and y = -3 so,

Answer:

Step-by-step explanation:

That"ll be 37% hope this helps:))

Step-by-step explanation:

To solve this problem, we can use the law of cosines. The law of cosines states that for any triangle with sides a, b, and c, and an angle C opposite side c,

c² = a² + b² - 2abcos(C)

In this problem, we can consider the man's starting point as the origin, and the distance he travels in the first leg as the first side of the triangle (a = 4km). The distance he travels in the second leg is the second side of the triangle (b). The angle between the two legs is the angle opposite side c, which is 90 degrees since the man changes direction from due west to southwest.

Therefore, we can use the law of cosines to find the distance he traveled in the second leg:

c² = a² + b² - 2abcos(90)

c² = 4² + b²

c = √(4² + b²)

c = √(16 + b²)

We know that the bearing of the second leg is 197 degrees, which is equivalent to a bearing of -163 degrees, since bearing measurements are taken clockwise from due north.

So we can use the law of cosines to find the distance he traveled in the second leg:

b = √(c² + a² - 2ac cos (-163))

We can now plug in the values we know:

b = √(c² + 4² - 24c*cos(-163))

We can now solve for c:

c = √(b² + 16 - 8bc)

The man is then southwest of his starting point, so the distance from his starting point to the final point is c.

There are 52 cards in a deck.

There are 3 face cards of each of 4 suits in a deck, so there are 12 face cards in a deck.

Taking all cards at once is the same as taking one card at a time with no replacement.

First card: p(face card) = 12/52 = 3/13

Now there are 11 face cards and a total of 51 cards left.

Second card: p(face card) = 11/51

Now there are 10 face cards and a total of 50 cards left.

Third card: p(face card) = 10/50 = 1/5

Now there are 9 face cards and a total of 49 cards left.

Fourth card: p(face card) = 9/49

Now there are 8 face cards and a total of 48 cards left.

Fifth card: p(face card) = 8/48 = 1/6

Since each drawing of a card is an independent event, the overall probability of drawing 5 face cards is the product of the individual probabilities.

p(5 face cards) = 3/13 × 11/51 × 1/5 × 9/49 × 1/6

p(5 face cards) = 33/108290 = 0.000305

what are expressions?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.

e.g. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.

The Raichu card was made 8 years ago.

To calculate this, we need to take into account the age of the Mewtwo card, the Snorlax card, and the Raichu card.

The Mewtwo card is twice as old as the Snorlax card, so the Mewtwo card is two years old. The Raichu card is five times as old as the Snorlax card, so it must be ten years old.

Since the Raichu card is two years older than the Mewtwo card, it must be eight years old. Therefore, the Raichu card was made eight years ago.

Similarly here we have take that xy|z means xy is a factor of z,

=> x × ym = z, and ym is an integer by closure hence x is a factor of z such that x|z.

Similarly here we can also y * xm = z, and consider xm is an integer, hence y is a factor of z, i.e. y|z.

Where in the third one, we can take x|y means there exists a constant is written as y = kx

Where as y|x means there exists a constant written as x = cy

When we compare these, then we get,

The slope of the line represented by 4x-7y=62 is 4/7. A line's steepness is measured by its slope. The mathematical expression for slope is "rise over run."

Option A is correct.

In mathematics, a line's slope is the ratio of the change in the y coordinate to the change in the x coordinate. The net change in the y-coordinate and the net change in the x-coordinate, respectively, are denoted by the symbols delta y and delta x.

          We are given equation as 4x-7y=62

First, let's write it in the slope-intercept form .In general, slope-intercept form is                                    y=mx + b

where m is the slope

So, writing the equation in the form, we get

                                    ⇒-7y = 62-4x

                                        ⇒7y = 4x-62

                                          ⇒y = 4x/7-62/7

Now, matching the equation with the general form,

                                          m = 4/7

Hence, the slope of the line represented by 4x-7y=62 is 4/7.
