Melissa has a student dictionary on her desk. Her dictionary contains 99 pages. In this dictionary, more words start with the letter "S" than any other letter, occupying 11 full pages.

If she opens up the dictionary at random, what is the probability that the page contains words starting with "S"?

Answers

Answer 1

Answer:

I believe it is 1/9 or 11.1%

Step-by-step explanation:

11/99 /(divided by) 11 = 1/9

1/9 converted to a decimal is 0.1 (it's repeating- I am not sure how to do that on brainly w/ the fancy - over it, so it's 0.111111111...)

so as a percent, it makes it 11.1% (repeating) or 11 [tex]\frac{1}{9}[/tex]% (which is a more exact solution)

now if you need a ratio, it would be 1:9

hope this helps :)

The value of y is directly proportional to the value of x. If y = 45 when x = 140, what is the value of y when x = 70?​

Answers

Step-by-step explanation:

Y is directly proportional to X" can be rewritten as a mathematical expression of the form Y = KX

"K" is the constant of proportionality and must be determined from the initial information.

If Y = 45 when X=140 means 45 = 140K

K = 45/140 = 0.32

Now that we know the value of K, we can use it to calculate the value of Y when X=70

Y = (0.32)(70) = 22.4

find an equation and the slope of the line that passes through (5,2) and is perpendicular to the x-axis

y=2; The slope is undefined.

x=5; The slope is 0.

y=2; The slope is 0.

x=5; The slope is undefined.

Answers

Solution: x = 5; The slope is undefined.

The slope that is perpendicular to the x-axis is undefined.

Explanation:

Given point: (5,2)

Since the line is perpendicular to the x-axis, then, the line is vertical.

Hence, x = 5

Answer:

x = 5, the slope is undefined

Step-by-step explanation:

Hello!

To be perpendicular to the x-axis, the line has to intersect at a 90° angle, causing it to be a vertical line with an undefined slope.

This removes the two middle options, as they have a slope of 0.

Consequently, looking at the two options, y=2, and x=5, y=2 would give us a parallel line to the x-axis, as we are drawing a line through all points with a y-coordinate of 2.

The correct option is x=5.

f(x)=−2x+16
g(x)=4x+10
please give me the intersection points

Answers

Answer:

(1, 14)

Step-by-step explanation:

The intersection is when both functions have same coordinates

f(x) = g(x)

Substitute to get

- 2x + 16 = 4x + 104x + 2x = 16 - 106x = 6x = 1

The y- coordinate is

y = - 2(1) + 16 = -2 + 16 = 14

So the intersection point is (1, 14)

Answer:

(1, 14)

Step-by-step explanation:

Given functions:

[tex]\begin{cases}f(x)=-2x+16\\g(x)=4x+10\end{cases}[/tex]

Substitute the function notation for y to create a system of equations:

[tex]\begin{cases}y=-2x+16\\y=4x+10\end{cases}[/tex]

To find the points of intersection of the given functions, solve the system of equations.

Multiply the first equation (function f(x)) by 2:

[tex]\implies 2y=-4x+32[/tex]

Add this to the second equation (function g(x)) to eliminate x:

[tex]\begin{array}{r l}4x+10 & = y\\+ \quad -4x+32 & = 2y\\\cline{1-2} 42 & = 3y\end{array}[/tex]

Solve for y:

[tex]\implies 3y=42[/tex]

[tex]\implies y=14[/tex]

Substitute the found value of y into one of the equations and solve for x:

[tex]\implies 4x+10=14[/tex]

[tex]\implies 4x=4[/tex]

[tex]\implies x=1[/tex]

Therefore, the point of intersection of the given functions is (1, 14).

Question 14 of 15
Len wants to learn more about red kangaroos. Which of the following is a
statistical question Len could ask?
O A. How tall is a red kangaroo?
O B. Are there red kangaroos in Asia?
• C. Are red kangaroos an endangered species?
O D. What iS the tallest red kangaroo ever recorded?

Answers

Answer:

A statistical question Len could ask is "How tall is a red kangaroo?"

Step-by-step explanation:

A statistical question is something that we can ask and test hypotheses about using collected data. There will not be a specific answer, but rather multiple answers and we can average them in a sampling distribution.

Let's examine each question:

"How tall is a red kangaroo?"

There is not a specific height for each kangaroo, so we can take the averages of many different samples and find the "true mean" in the sampling distribution. This is a good example of a statistical question because data can be collected on red kangaroos and means can be calculated.

"Are there red kangaroos in Asia?"

"Are red kangaroos an endangered species?"

What is the tallest red kangaroo ever recorded?"

These are all examples of non-statistical questions. They are "yes" or "no" questions, and we cannot take multiple samples to determine the answer. Rather, there is a single answer that we do not need to test hypotheses or perform any statistical calculations.

Step-by-step explanation:

Area of Rectangle: Area = Length * Width

Given information:

Area = 22 in^2Length = 2x - 1Width = x - 4

Put that into the Formula.

Area = Length * Width

22 in^2 = (2x - 1) * (x - 4)

Solve.

22 in^2 = (2x - 1) * (x - 4)

[tex]22 = (2x^2 - 9x + 4)\\2x^2 - 9x - 18 = 0[/tex]

Factor it.

(2x^2 - 9x - 18) = 0

(2x + 3)(x-6) = 0

[tex]x=-\frac{3}{2} ,6[/tex]

Plug that into the Length and Width to find the actually Length and Width.

Length:
