No, the frequencies do not decrease from the maximum frequency to a low frequency

Answer:

Yes, all the requirements are met.

Step-by-step explanation:

Frequency Distribution is a graph or table which shows the frequency of different outcome.

Normal Distribution has bell like-shape.

Since here the value of frequency is less for score 50-69 then it increases from 70- 109 then the frequency is again decreasing from score 110-149. So the curve of frequency distribution when plotted appears like bell-shaped. Hence, It appears like a normal distribution.

Vertical angles are congruent. Option A

Vertical angles are pairs of angles formed by the intersection of two lines or line segments, where the angles are opposite each other and share a common vertex but do not share any sides.

Vertical angles are always congruent, meaning they have equal measures.

For instance, in an "X" shape formed by two intersecting lines, the angles opposite each other at the intersection are vertical angles.

Answer:

410

Step-by-step explanation:

The sum of 3/8 and 1/4 is 5/8. Therefore, any expression that sums up to 5/8 will have the same sum as 3/8 + 1/4.

To find the expression that has the same sum as 3/8 + 1/4, we need to first compute the sum of the given fractions. When summing fractions, we need the denominators to be the same. In this case, 8 and 4 could both be divisible by 2, so we need to convert the second fraction to have the denominator of 8:

3/8 + 2/8 = 5/8

Therefore, the expression that will have the same sum as 3/8 + 1/4 is any other expression that also amounts to 5/8. Examples could be 2/8 + 3/8 or even 5/8 + 0.

To find an expression with the same sum as 3/8 + 1/4, we need to find a common denominator and add the fractions. The expression with the same sum is 5/8.

To find an expression with the same sum as 3/8 + 1/4, we need to find a common denominator.

The least common multiple of 8 and 4 is 8, so we can rewrite 3/8 as 3/8 × 1 = 3/8 × 2/2 = 6/16.

Now we can add 6/16 + 1/4, which equals (6 + 4)/16 = 10/16.

Simplifying this fraction gives us 5/8. Therefore, the expression with the same sum as 3/8 + 1/4 is 5/8.

Answer:

79.25 square inches

Step-by-step explanation:

To find the area of the figure, split it into two shapes - a rectangle and a semi-circle.

The area of a rectangle is A = b*h. Substitute b = 10 and h = 4.

A = 4*10 = 40.

The area of a semi-circle is A =1/2 πr². Substitute r = 5 since the diameter is 10.

A =1/2 π5² = 12.5π = 39.25.

Add the two areas together.

39.25 + 40 = 79.25

Answer: The total is $12,250.

Step-by-step explanation: First, we will calculate the amount that Hillary has deposited over the past 35 years. She has deposited $200 for each of the past 35 years. The total that she has deposited is 200 x 35 = $7,000.

Her employer also deposits into her account 75% of what she has deposited. In order to calculate their contribution you need to multiply $7,000 x .75 = $5,250.

The total that has been deposited into the account is $7,000 + $5,250 = $12,250.

Hillary's total contribution over the 35 years was $84,000. The employer matched 75% of Hillary's contribution, totaling $63,000. The combined contribution of Hillary and her employer for 35 years is $147,000.

Hillary has been depositing $200 into her 401(k) per month for the past 35 years. For 35 years, there are a total of 35 times 12 months which equals 420 months. Given this, Hillary has contributed $200 times 420 months which is $84,000.

Her employer has a 75% match on all her contributions. This means they are adding another 0.75 times the $84,000, which equals $63,000.

Therefore, the total contribution by both Hillary and her employer over the 35 years is both amounts added together: "$84,000 (Hillary’s contribution) + $63,000 (Employer match) = $147,000".

Answer:

No 1 inch cubes will fit

28 one-half inch cubes will fit

Step-by-step explanation:

No cubes with a side length of 1 inch will fit because one dimension of the prism is only 1/2 inches, so we can't fit a 1 inch cube in anywhere.

Since one dimension is 1/2 inch, we can line up 1/2 inch cubes along the other 2 dimensions.  Let's say that the 1/2 inch dimension is the base, the 2 inch dimension is the height, and the 7/2 inch dimension is the length.

We can stack the cubes 4 high, (2 inches of height with 1/2 inch being the cube height, there are 4 halves in 2).

We can place 7 cubes along the length (7/2 inches = 3.5 inches.  There are 7 halves in 3.5).  

So we can have 4(7) = 28  one half inch cubes can fit in to the prism

Answer:

option D

D. x = 5, y = 2

Step-by-step explanation:

Given in the question two equation,

Equation 1

5.3x + y = 28.5

Equation 2

4.2x + 3.1y = 27.2

rearrange equation 1 in terms of y

y = 28.5 - 5.3x

Substitute the value of y in equation 2

4.2x + 88.35 - 16.43x = 27.2

4.2x - 16.43x = 27.2 - 88.35

-12.23x = -61.15

x = 61.15/12.23

x = 5

put value of x in any of the equation

y = 28.5 - 26.5

y = 2

Step-by-step explanation:

You can superimpose a triangle in this situation.  The height from the ground to the top of the ladder along the wall is one leg of the triangle, the distance the ladder is from the wall is the other leg, and the length of the ladder is the hypotenuse.  

Use Pythagorean theorem to solve, which is a² + b² = c² where a, and b are the legs, and c is the hypotenuse...

We have

7² + 24² = c²

   49 + 576 = c²

       625 = c²

        25 = c

Answer:

x = 5√3; y = 5

Step-by-step explanation:

Finding y:  The sine function links the 30° angle, the 10 unit hypotenuse and the side opposite the angle, y:

sin 30° = 1/2 = y/10

Solve the equation of ratios

1        y

-- = -----  using cross-multiplication first:  2y = 10 → y = 5

2     10

We can now find x either by using a similar approach and the cosine function or by using the Pythagorean Theorem:

x² + y² = 10² = 100  →  x² = 100 - y²  =  100 - 5²  = 75

If x² = 75, then x = ±√75 = ± (√25)·(√3)   →  ±5√3

Since lengths are always positive,   take x = 5√3 as the answer.

Answer:

Reflection across the line y=x followed by translation 10 units to the right and 4 units up.

Step-by-step explanation:

Triangle ABC has vertices at points A(-6,2), B(-2,6) and C(-4,2).

1. The reflection across the line y=x has the rule

(x,y)→(y,x).

Thus,

2. The translation 10 units to the right and 4 units up has the rule

(x,y)→(x+10,y+4).

Thus,

Points A'B'C' are exactly the vertices of the triangle A'B'C'.

The sequence of transformations that maps triangle ABC to triangle A’B’C’ is a reflection across the y-axis, followed by a translation 8 units to the right and 10 units up.

The sequence of transformations that maps triangle ABC to triangle A’B’C’ is a reflection across the y-axis, followed by a translation 8 units to the right and 10 units up.

First, the reflection across the y-axis changes the x-coordinate to its opposite. So, the new coordinates of point A are (-2, 5), the new coordinates of point B are (-3, 2), and the new coordinates of point C are (-5, -1).

Next, the translation moves the triangle 8 units to the right and 10 units up. So, the new coordinates of point A are (6, 15), the new coordinates of point B are (5, 12), and the new coordinates of point C are (3, 9).

Answer:

Step-by-step explanation:

Each factor corresponds to a zero of the function.

If (x+4) is set = to 0, the corresponding root is x = -4.

If (-7x - 60) is set = to 0, the corresponding root is x = -60/7.

The factors (-7x-60)(x+4) represent the roots or solutions of the original quadratic equation in its expanded form, which are obtained by setting each factor equal to zero and solving for x.

The factors (-7x-60)(x+4) in the factored form represents the roots of a quadratic equation. In a quadratic equation of the form ax² + bx + c = 0, the roots or solutions of the equation can be obtained by factoring the quadratic expression. In this case, the equation being factored must have been -7x² - 28x - 60x - 240 = 0. The roots are the values that make each factor equal to zero, so the roots of the original equation are obtained by solving -7x-60 = 0 and x+4 = 0, to get x = -60/(-7) = 8.57 and x=-4.
