When given a set of cards lying face down that spell M, A, T, H, F, A, N, determine the probability of randomly drawing a consonant.

six halves
six sevenths
five sevenths
two sevenths

Answers

Answer: five sevenths

Step-by-step explanation:

To determine the probability of randomly drawing a consonant from the set of cards, we first need to identify the consonants in the given letters: M, A, T, H, F, A, N.

From this set of letters, the consonants are M, T, H, F, and N. There are 5 consonants out of a total of 7 letters.

To calculate the probability, we divide the number of favorable outcomes (drawing a consonant) by the total number of possible outcomes (drawing any letter).

The probability of randomly drawing a consonant is:

Number of favorable outcomes: 5 consonants

Total number of possible outcomes: 7 letters

Therefore, the probability of randomly drawing a consonant is 5/7.

Expressing it as a fraction, the probability is five sevenths.

Therefore, the correct answer is five sevenths.

Two trains, Train A and Train B, weigh a total of 346 tons. Train A is heavier than Train B. The difference of their weights is 238 tons. What is the weight of each train?

Answers

Answer:

A=292, B=64

Step-by-step explanation:

A+B=346 equ 1

A>B

A-B=238 equ 2

A=238+B

input into equ 1

238+B+B=346

238+2B=346

collect like terms

2B=346-238

2B=108

divide both sides by 2

B=54

A=238+B

A=238+54

A=292

5)= U(-3,0), M(-1,4), L(-2,0)

6)= R(-4,2), D(-4,5), L(0,2)

Step-by-step explanation:

The x shouldn't change. If this isn't correct, I apologize. But I'm sure I calculated this right.

The coordinates of the figure after a translation of 5 units up is U' ( -3 , 1 ) , M' ( -1 , 4 ) and L' ( -2 , 0 )

The coordinates of the figure after a translation of 3 units up is R' ( -4 , 0 ) , D' ( -4 , 4 ) , L' ( 0 , 3 ) and F' ( 0 , 0 )

What is Translation?

A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.

A translation in the coordinate plane moves every point on a figure a given distance in a given direction. The position of any point (x, y) on the figure changes to (x + a, y + b), where a and b are real numbers.

Given data ,

Let the translated figure be represented as A

Now , the coordinates of the figure are

The coordinates of the figure are U ( -3 , -4 ) , M ( -1 , -1 ) and L ( -2 , -5 )

And , when the translation is up , the y coordinate increases by d units

The coordinates of the figure after a translation of 5 units up is U' ( -3 , 1 ) , M' ( -1 , 4 ) and L' ( -2 , 0 )

The coordinates of the figure are R ( -4 , -3 ) , D ( -4 , 0 ) and L ( 0 , 0 ) and F ( 0 , -3 )

And , when the translation is up , the y coordinate increases by d units

The coordinates of the figure after a translation of 3 units up is R' ( -4 , 0 ) , D' ( -4 , 3 ) , L' ( 0 , 3 ) and F' ( 0 , 0 )

Hence , the translation is solved

To compare the measures of center of two data sets as a multiple of their measures of variation, their measures of variation must be similar. Why do you think this is true?

Answers

To compare two data sets, their variation must be similar because the variation will affect many other variables, including the mean.

What is the variation?

When referring to data, the variation is about how much the data variates or the range of the data. For example, if you ask people about their age, the data can spread from 10 years old to 90 years old.

Why is variation important?

This affects other variables when analyzing data such as the mean, which implies you can only compare two sets of data if the variation is similar.

A biologist is studying the growth of a particular species of algae. She writes the following equation to show the radius of the algae, f(d), in mm, after d days:

f(d) = 9(1.04)d

Part A: When the biologist concluded her study, the radius of the algae was approximately 12.81 mm. What is a reasonable domain to plot the growth function? (4 points)

Part B: What does the y-intercept of the graph of the function f(d) represent? (2 points)

Part C: What is the average rate of change of the function f(d) from d = 3 to d = 9, and what does it represent?

Answers

Answer:

Step-by-step explanation:

Part A: A reasonable domain to plot the growth function would be from 0 to a reasonable maximum number of days, such as 30 or 60, depending on the duration of the study.

Part B: The y-intercept of the graph of the function f(d) represents the initial radius of the algae when d = 0, which would be 9 mm.

Part C: To find the average rate of change of the function f(d) from d = 3 to d = 9, we can calculate the difference in the function values at these two points and divide it by the difference in the input values. The average rate of change represents the average growth rate of the algae over that time period.

Solve For Z & X

Answer choices for Z -
$1.51
$25.08
$33.93
$26.59

Answer choices for X -
$22.35
$1.27
$3.72
$383.66

Answers

To solve for Z and X simultaneously, you can use the following equation: Z + X = 59.5 You can then compare the four given answer choices for Z and X to determine which ones satisfy the equation. For example, $1.51 + $22.35 = $23.86, which is not equal to 59.5, so neither of these answer choices is correct. However, $25.08 + $3.72 = $28.80 which is equal to 59.5, so the correct answer choices for Z and X are $25.08 and $3.72, respectively.

Which quadrilaterals always have diagonals that bisect opposite angels? A. Parallelograms B. Rectangles C. Rhombi D. Squares

Answers

Answer:

All of the above

Step-by-step explanation:

All of the given quadrilaterals have diagonals that bisect each other

Answer:

C. Rhombi

D. Squares

Step-by-step explanation:

You want to know which quadrilaterals always have diagonals that bisect opposite angles.

Angle bisector

In order for a diagonal of a quadrilateral to bisect opposite angles, it must be equidistant from the sides of the angles. In effect, the sides of the angle must be the same length, and the angle-bisecting diagonal must be perpendicular to the other diagonal.

This will be the case for a kite, rhombus, or square. Among the answer choices are ...

RhombiSquares

Additional comment

A kite has two pairs of congruent adjacent sides. The angle-bisecting diagonal bisects the angle between the congruent sides. The diagonals are not necessarily the same length, and one is bisected by the other. That is, a kite is not a parallelogram.

A rhombus is a kite with all sides congruent. The diagonals bisect each other. A rhombus is a parallelogram. Both diagonals are angle bisectors.

A square is a rhombus with equal-length diagonals.

A spinner with repeated colors numbered from 1 to 8 is shown. Sections 1 and 8 are purple. Sections 2 and 3 are yellow. Sections 4, 5, and 6 are blue. Section 7 is red. Determine the theoretical probability of the spinner not landing on yellow, P(not yellow).

Answers

Answer: 0.75 or [tex]\frac{3}{4}[/tex]

Step-by-step explanation: Well there are 2 section colored purple, 2 sections yellow, 3 sections are blue, and 1 section is red.

First lets find the number of favorable outcomes, which would be outcomes with out yellow. 6 out of 8 sections do not have yellow therefore the amount of favorable outcomes is 6.

Now for the total amount of outcomes which is 8.

If we input those numbers in this formula [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex] so [tex]\frac{6}{8}[/tex] we get 0.75 or [tex]\frac{3}{4}[/tex].
