Answer:

half of pattern A + pattern B

Step-by-step explanation:

Its half of pattern A + pattern B

If we say when pattern A is 8 what is pattern b

8/2 + 8

4 + 8 = 12

This matches with the chart so half of pattern A + pattern B is correct

Rewrite 19/5 as a mixed number.<br> 1. 4^2/5<br> 2. 3^4/5<br> 3. 5^3/4<br> 4. 4^1/5

Nadusha1986 [10]

Answer:

3 4/5

3 1/5
16 1/5
31 1/4
4/5

Step-by-step explanation:

An improper fraction is converted to a mixed number by doing integer division and expressing the remainder as a fraction with the divisor as the denominator.

... 19/5 = (3·5 +4)/5 = 3 4/5

The expressions involving exponents are evaluated to mixed numbers according to the Order of Operations. The exponent is evaluated before division, so ...

1. 4^2/5 = (4^2)/5 = 16/5 = 3 1/5

2. 3^4/5 = (3^4)/5 = 81/5 = 16 1/5

3. 5^3/4 = (5^3)/4 = 125/4 = 31 1/4

4. 4^1/5 = (4^1)/5 = 4/5

_____

If you intended fractional exponents, according to the Order of Operations, you need to put that fraction in parentheses. The denominator of the fraction is the root of the base number to the numerator power.

... 4^(2/5) = (4^2)^(1/5) = 16^(1/5) = $\sqrt[5]{16}$

What is the quadratic regression equation for the data set? <br><br> PLEASEE HELP ME

Soloha48 [4]

You're trying to find constants $a_0,a_1,a_2$ such that $\hat y=a_0+a_1\hat x+a_2{\hat x}^2$ . Equivalently, you're looking for the least-square solution to the following matrix equation.

$\underbrace{\begin{bmatrix}1&6&6^2\\1&3&3^2\\\vdots&\vdots&\vdots\\1&9&9^2\end{bmatrix}}_{\mathbf A}\underbrace{\begin{bmatrix}a_0\\a_1\\a_2\end{bmatrix}}_{\mathbf x}=\underbrace{\begin{bmatrix}100\\110\\\vdots\\70\end{bmatrix}}_{\mathbf b}$

To solve $\mathbf{Ax}=\mathbf b$ , multiply both sides by the transpose of $\mathbf A$ , which introduces an invertible square matrix on the LHS.

$\mathbf{Ax}=\mathbf b\implies\mathbf A^\top\mathbf{Ax}=\mathbf A^\top\mathbf b\implies\mathbf x=(\mathbf A^\top\mathbf A)^{-1}\mathbf A^\top\mathbf b$

Computing this, you'd find that

$\mathbf x=\begin{bmatrix}a_0\\a_1\\a_2\end{bmatrix}\approx\begin{bmatrix}121.119\\-3.786\\-0.175\end{bmatrix}$

which means the first choice is correct.

Georgia said she could make 11 out of 20 blankets for a craft show. She has already made 3 blankets. What percent of the 20 blan

rewona [7]

Answer:

Step-by-step explanation:

Total she can make = 11

Amount she has already made = 3

Amount she still have to make = 11-3 = 8

% of the 20blanket she still have to make = 8/20×100

= 8×5

= 40%

Hence she Still need to make 40% of the 20blanket

How do you find change in y when given slope and change in y pls help WILL GIVE BRAINLIEST!!!

arlik [135]

The slope (m) is the change in Y over the change in X.

Slope = Y/X

The slope is given as -3/4 , so y would be 3 and X would be 4.

Y = 3
