What function is represented by the mapping diagram shown?

O A. F(x)= x+3
O B. F(x)= x-3
O C. F(x) = 3x
O D. F(x) = 1

Answer:

x ≈ 7.2

Step-by-step explanation:

Given a tangent- secant from an external point to the circle, then

the the square of the measure of the tangent is equal to the product of the external part of the secant and the entire secant, that is

x² = 4(4 + 9) = 4 × 13 = 52 ( take the square root of both sides )

x = [tex]\sqrt{52}[/tex] ≈ 7.2 ( to the nearest tenth )

Step-by-step explanation:

1. x= 11.7 μ = 7

2. z11.7 = 1.3

3. A

4. B

The value of the z-score is 1.33.

The z-score is defined as the mean (average) values, measured in terms of standard deviations from the mean.

The formula is used to calculate z-score is;

Z-score = (X-μ)/σ

We have, mean = 7 and σ =3.522 and X is  11.7.

Substitute all the values in the formula;

Z-score = (X-μ)/σ

= (11.7-7)/3.52

= 4.7/3.52

= 1.33

Hence, the value of the z-score is 1.33.

Answer:

That amount is 6 STUDENTS out of 24 students.

Step-by-step explanation:

Please see the attached files for more information.

Final answer:

To calculate the amount representing 25% of the 24 students Kaitlyn sampled, an equation using equivalent fractions and cross-multiplication is set up. The equivalent fractions are 25/100 and x/24. After cross-multiplying and solving for x, we find that 6 students (x) raised more than a certain amount for the charity.

Explanation:

If Kaitlyn wants to make the statement that 25% of the 24 students she sampled raised over a certain amount for the charity, we would need to determine what number of students that percentage represents. To calculate this, we use the phrase “part over total, times one hundred, equals percent.” Applying this to Kaitlyn's situation, we would set up an equation using equivalent fractions and then cross-multiply to find the part.

For the equivalent fraction, we have 25/100 (since 25% is the same as 25/100) and we let the part be x/24 (where x is the number of students who raised over a certain amount). The equation would then be 25/100 = x/24.

By cross-multiplying, we have 25 * 24 = 100 * x, which simplifies to 600 = 100x. Therefore, after dividing both sides of the equation by 100, we find that x = 6. Thus, Kaitlyn is saying that 6 out of the 24 students raised more than a certain amount for the charity.

Answer: expanded factor form would be 6 x 100 + 7 x 10 + 4 x 1 + 2 x 0.1 +8 x 0.01 +1 x 0.001

Step-by-step explanation:

It depends on what the percents are measuring but the difference is that a percent increase=more of something and a percent decrease=less of something. The difference are in the numbers/quantity.

So the right answer is 3.

Answer:

1. a=1 b=9 c=20

(x+5) (x+20)

2. a=1 b=2 c=-8

(x-2)(x+4)

Step-by-step explanation:

When you use the box method, follow these steps (only usable when a=1)

(i'll be using x^2+9x+20 as an example)

be sure to understand that the formula is ax^2+bx+c

1. the top left corner is a, so put x^2

2. the bottom right is the c, or the y intercept. that would be 20 when using x^2+9x+20

3. find 2 numbers that when multiplied equal c and when added equal b. in this problem, 4(5)=20 and 4+5=9, so 4 and 5 belong in the remaining 2 boxes. make sure to add the x after each term, since these terms are b.

4. find to common term in each row of the box (x^2 and 4x share x, and 5 and 20 share 5) and then the common terms in the columns (x^2 and 5x share x and 4 and 20 share 4)

this should give you (x+4)(x+5)

Answer:

c because one is acute the other is scalene

Answer:

case A. Three angles measuring 25,65,and 90

sum of a internal angles=25+65+90-----> 180° is ok

That dimensions can create infinity similar triangles

case B. Three angles measuring 50,50,and 50

sum of a internal angles=50+50+50----> 150°  is not a triangle

therefore

That dimensions cannot create a triangle

case C. Three sides measuring 5 in,12 in,and 14 in

Applying the Triangle Inequality Theorem

5+12>14 -- >  is ok

14+5>12 --- > is ok

12+14>5 --- > is ok

That dimensions can create only one unique triangle

Answer:20 and 14

Step-by-step explanation:

Final answer:

The two numbers sought are 27 and 7, with 27 being the larger number and 7 being the smaller number, 20 less than 27. This is determined by setting up a system of equations based on the given conditions and solving for the two unknowns.

Explanation:

The question involves finding two numbers based on the conditions given: the sum of the two numbers is 34, and the smaller number is 20 less than the larger number. Let's denote the larger number as x and the smaller number as y. According to the conditions, we have two equations: x + y = 34 and y = x - 20.

We can substitute the second equation into the first to find the value of x: x + (x - 20) = 34, which simplifies to 2x - 20 = 34. Adding 20 to both sides gives us 2x = 54, and dividing both sides by 2 yields x = 27. Now that we know the larger number, we can find the smaller number by substituting x into the second equation: y = 27 - 20, which gives y = 7. Therefore, the two numbers are 27 and 7.

Answer:

61.69?

Step-by-step explanation:

Are you asking what 31% of 119 is? If so, then the answer would be 61.69.

Because (119)0.31=61.69

(To make a percent, you take a decimal out of 1, and multiply. 0.31 would be 31, because we would multiply it by 100, becuase you can only get to 100%. Then you woukd do the opposite, reverse it by dividing by 100. Which then, you would get 0.31)

Answer:

it is about 1.13 so the closest would be letter A.

Step-by-step explanation:

[tex]A=4\pi r^{2}[/tex] We plug it into this formula

[tex]r=\frac{1}{2} \sqrt{\frac{A}{\pi } } =\frac{1}{2} *\sqrt{\frac{16}{\pi } }[/tex] This gives us ≈1.12838

6. 02 rad. is the value of conversion of the angle 0 = 345° to radians.

Here, we have,

given that,

Convert the angle theta = 345° to radians.

To convert from degrees to radians, multiply the number of degrees by π/180.

This will give you the measurement in radians.

If you have an angle that's 90 degrees, and you want to know what it is in radians, you multiply 90 by π/180. This gives you π/2.

here, angle = 345°

We convert degrees to radian by multiplying by (π/ 180)

=(345)×(π/ 180)

=( 345/180)×(π)

=1.9166π

=1.9166×3.14

=6.018 rad

≈6.02 rad .
