Answer:
x=14.28
Step-by-step explanation:
24^2+x^2=28^2, Pythagorean theorem
x^2=28^2-24^2
x^2=(28+24)(28-24)
x^2=52*4
x^2=204
x is around 14.28

Answer:
14 one fourths
Step-by-step explanation:
First, we convert 7/2 into a fraction with the denominator of a four. To do this, we multiply the top and bottom by 2. 7*2 is 14, and 2*2 is 4, which gives us 14/4. This means that there are 14 one fourths in 7/2. Hope this helps!
Answer:
14 fourths
Step-by-step explanation:
Hey There!
So to solve this problem we need to divide 7/2 by 1/4
[tex]\frac{7}{2}divided by\frac{1}{4} =14[/tex]
Therefore 14 fourths can go into 7/2

Complete each of the following statements with the letter that represents the expression.

(3x2 7x + 14) + (5x2 + 41 6) is equivalent to expression
(2x2 – 5x – 3) + (-10x2 + 2x + 7) is equivalent to expression
(12t2 – 2x – 13) + (-4x2 + 5x + 9) is equivalent to expression
Answer/Step-by-step explanation:
✔️(3x² - 7x + 14) + (5x² + 4x - 6)
3x² - 7x + 14 + 5x² + 4x - 6 (distributive property)
Add like terms
3x² + 5x² - 7x + 4x + 14 - 6
8x² - 3x + 8
Therefore:
✅(3x² - 7x + 14) + (5x² + 4x - 6) is equivalent to expression 8x² - 3x + 8.
✔️(2x² - 5x - 3) + (-10x² + 2x + 7)
2x² - 5x - 3 - 10x² + 2x + 7 (distributive property)
Add like terms
2x² - 10x² - 5x + 2x - 3 + 7
-8x² - 3x + 4
Therefore:
✅(2x² - 5x - 3) + (-10x² + 2x + 7) is equivalent expression to -8x² - 3x + 4
✔️(12x² - 2x - 13) + (-4x² + 5x + 9)
12x² - 2x - 13 - 4x² + 5x + 9
12x² - 4x² - 2x + 5x - 13 + 9
8x² + 3x - 4
Therefore:
✅(12x² - 2x - 13) + (-4x² + 5x + 9) is equivalent expression to 8x² + 3x - 4

Suppose John is a high school statistics teacher who believes that watching many hours of TV leads to lower test scores. Immediately after giving the most recent test, he surveyed each of the 24 students in his class and asked them how many hours of TV they watched that week. He then matched each student's test grade with his or her survey response. After compiling the data, he used hours of TV watched to predict each student's test score. He found the least-squares regression line to be

Suppose John is a high school statistics teacher who believes that watching many hours of TV leads to lower test scores. Immediately after giving the most recent test, he surveyed each of the 24 students in his class and asked them how many hours of TV they watched that week. He then matched each student's test grade with his or her survey response. After compiling the data, he used hours of TV watched to predict each student's test score. He found the least-squares regression line to be y" = -1.5x + 85.
He also calculated that the value of r, the correlation, was -0.61.
what is the correct value of the coefficient of determination R² and give a correct interpretation of its meaning
Answer:
Interpretation of coefficient of determination R² = 0.3721
R² = 0.3721, meaning 37.21% of the total variation in test scores can be explained by the least square regression line
Step-by-step explanation:
Given the data in the question;
the least square regression line is;
y" = -1.5x + 85
the correlation coefficient r = -0.61
Now, the coefficient of determination R² is square of correlation coefficient r
R² = -61²
R² = 0.3721
Please help solve this angle problem! It is due today!
Answer:
The answer is B.
Step-by-step explanation:
Two angles that add up to 90° are called complementary angles.
Angles A and B are complimentary angles. Complimentary angles are angles which add up to exactly 90 degrees.
They are often confused with supplementary angles, but supplementaries add up to 180.

Answer:
Nathan must order 21 sets of forks for the restaurant.
Step-by-step explanation:
Since Nathan needs to order some new supplies for the restaurant where he works, and the restaurant needs at least 571 forks since there are currently 361 forks, if each set on sale contains 10 forks, to determine the number of sets to buy you must perform the following calculation:
(571 - 361) / 10 = X
210/10 = X
21 = X
So Nathan must order 21 sets of forks for the restaurant.

Which shows the equation below written in the form ax^2+bx+c=0. x+9=4(x-1)^2
Answer:
[tex]4x^2 - 9x - 5 = 0[/tex]
Step-by-step explanation:
To place the equation in standard form, we expand the operations. So
[tex]4(x-1)^2 = x + 9[/tex]
[tex]4(x^2-2x+1) = x + 9[/tex]
[tex]4x^2 - 8x + 4 - x - 9 = 0[/tex]
Combining the like terms:
[tex]4x^2 - 9x - 5 = 0[/tex]

Find sequence 10 5/22, 9, 7 17/22, ___, 5 7/22
Answer:
6⁶/11
Step-by-step explanation:
adding -27/22 to the previous number will give you the next number in the sequence
10 5/22 + -27/22 = 9
9 + -27/22 = 7 17/22
7 17/22 + -27/22 = 6 6/11
6 6/11 + -27/22 = 5 7/22
