Taj asked 27 classmates whether they know how to write calligraphy. He used a calculator to compare the number of classmates who said yes to the total number he surveyed. The calculator showed the result as 0.111111111. How many students know how to write calligraphy?

A simple algebra equation!

You have to replace each x with 4, so the equation would look like this:

-4·4+1.5·4-2.5-2·4-6.5

Evaluate the terms, you get:

-16+6-2.5-8-6.5

Then you add and subtract where needed:

-10-16 = -27

And that's the final answer!

ANSWER: 27

Answer:

24.5

Step-by-step explanation:

35% of 70 is  24.5

so 70 plus 24.5 = 94.5

===========================================================

Explanation:

Add up the numbers in the second column:

4+19+25+32 = 80

There are 80 people being surveyed in the table.

Of those 80 people surveyed, 32 of them exercised for more than 136 minutes.

The probability of selecting someone who exercised for more than 136 minutes is the fraction 32/80 = (16*2)/(16*5) = 2/5

----------

Multiply this probability with the larger sample size of 300 to get

(2/5)*300 = 0.4*300 = 120

We estimate that 120 people would exercise for more than 136 minutes.

Note that 120/300 = 2/5.

Answer:

E

Step-by-step explanation:

"S" stands for "side" and "A" stands for "angle"

SAS = side angle side

The order is important because the angles must be between the two congruent sides.

One pair of congruent sides is AC = CE as shown by the single tickmarks.

The other pair of congruent sides is BC = CD shown by the double tickmarks

The congruent angles are the vertical angles BCA and DCE. Vertical angles are always congruent. Note how these angles are sandwiched between the tickmarked sides.

Answer:

The answer is  

her score was in the top 85% of all test takers' scores.

Step-by-step explanation:

Percentile is the relative standing in a set of data from the lowest values to highest values.

If your score is in the 85th percentile, it means that 85% of the scores are below your score and 15% are above your score.

Answer:

A. Her score was better than those of 85% of all test takers.

Step-by-step explanation:

This means that 85% of the students scored lower on the test, so approximately 15% scored higher.

Answer:

HOPE THIS HELPS

Step-by-step explanation:

You need to first plot the points on the graph.

Since, it says you need to reflect across x axis, you need same number of square units.

For example, P has the coordinates( -2,3 ). -2 lies on the x axis, so the point doesn't go neither left nor right. It is 3 squares above the x axis, so the reflected point should be 3 squares below the x axis. Likewise, you can do the other points.

Hope it helps :)

Answer: everything looks correct from my side

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

We have the graph of the function f(x).

We want to determine which of the given is true of the graph from [tex]x=g[/tex] to [tex]x=\infty[/tex].

So, essentially, we are focusing on the last curve (see image below).

First, since the curve is above the x-axis, the curve is positive.

Second, since the curve is curving upwards, this means that it must be increasing. Another way to think about this is to think about the slope of our curve. While we can't calculate the exact slope, the average slope will be positive, so our function is increasing.

So, our answer is A.

And we're done!

What is the decimal equivalent to -3 3/12

[tex]\huge\rm{ANSWER:}[/tex]

[tex]\huge\rm{SOLUTION:}[/tex]

To begin, keep in mind that - 3 3/12 is a mixed number, also known as a mixed fraction. It has a valid fraction as well as a complete number.

The following is a list of the numbers in a mixed fraction:

[tex]\huge \rm{ - 3}[/tex] the whole number.

[tex]\huge \rm{ 3}[/tex] the numerator

[tex]\huge \rm{ 12}[/tex] the denominator

Follow these procedures to convert -3 3/12 from a mixed number to a decimal number:

Divide the denominator by the numerator to convert the correct fraction to decimal.

3 ÷ 12 = 0.25

To get the entire number of the mixed fraction, multiply it by this decimal number.

-3 + 0.25 = - 3.25

Therefore, the decimal equivalent to -3 3/12 is -3.25

Answer:

5040°

Step-by-step explanation:

assuming you mean the sum of the interior angles.

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 30 , then

sum = 180° × 28 = 5040°

Answer:

Step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 6 by 5 and keep only what is to the left of the decimal point:

6 / 5 = 1.2000 = 1

Step 2 - Find New Numerator

the answer from Step 1 by the denominator and deduct that from the original numerator.

6 - (5 x 1) = 1

Step 3 - Get Solution

Keep the original denominator and use the answers from Step 1 and Step 2 to get the answer. 6/5 as a mixed number is:

Step-by-step explanation:

Length of board will be 32 1/2 inch.

What is Addition?

A process of combining two or more numbers is called addition.

Given that;

Length of board after cutting are;

7 1/2 inches, 10 1/2 inches, 9 inches, and 5 1/2 inches.

Now, Total length of board is calculated as sum of all cut lengths.

So, Total length of board = 7 1/2 +10 1/2 + 9 + 5 1/2

                                      = 15/2 + 21/2 + 9 + 11/2

                                      = 47/2 + 9

                                      = 65/2

                                      = 32 1/2

Thus, Length of board will be 32 1/2 inch.

Step-by-step explanation:

Answer:

C 13

Step-by-step explanation:

2 right-angled triangles. so, Pythagoras applies for both.

c² = a² + b²

with c being the Hypotenuse (the side opposite of the 90° angle).

starting with the small triangle we have

5² = 3² + x-part²

x-part² = 5² - 3² = 25 - 9 = 16

x-part = 4 cm

the markers indicate that x-part as the third side of the small triangle is exactly as long as the other part of x.

that means

x = 2 × x-part = 2 × 4 = 8 cm

for the large triangle we then get

y² = x² + 15² = 8² + 225 = 64 + 225 = 289

y = 17 cm

and so,

y - x = 17 - 8 = 9

but that is not an answer option.

and now it dawned on me : x was not meant to be the whole third side of the large triangle. x is supposed to be only the upper part of that side, above the small triangle.

in essence, x is what I originally called "x-part".

so, the Pythagoras calculations remain basically the same, but we should name things differently like

5² = 3² + small-side²

small-side = 4 cm

x = small-side = 4 cm

long-side = 2 × small-side = 2 × 4 = 8 cm

y² = long-side² + 15² = 8² + 15² = 64 + 225 = 289

y = 17 cm

and the actual y - x = 17 - 4 = 13 cm
