Answer:

Step-by-step explanation:

$\sf a^{m}*a^{n} =a^{m +n}\\\\a^{\frac{1}{n}}=\sqrt[n]{a}$

$\sf a^{-n}=\dfrac{1}{a^{n}}\\\\\dfrac{a^{n}}{a^{m}}=a^{n-m}\\\\\\a^{0}=1$

$\sf (a^{n})^{m} = a^{n*m}\\\\(a^{n}*b^{m})^{p}=a^{np}b^{mp}\\\\(ab)^{n}=a^{n}b^{n}$

I did these about 1 year ago but i think you subtract the 6 from 30 and then divide by 4, and that gives u 24/4 which is 6. i barely barely remember some so

What is the numerator of the simplified expression? 2 n 3n-2 3n+2

Nat2105 [25]

Answer:

The numerator is n; Choice B

Step-by-step explanation:

The first step would be to factorize the expression;

6n+4 to become;

2(3n+2)

This term cancels out with the 2 and 3n+2 in the numerator leaving n as the only term.

Find the slope using the formula. (3,-2) and (3, 6)

dangina [55]

Answer:

m = undef

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (3, -2)

Point (3, 6)

Step 2: Find slope m

Substitute: $m=\frac{6+2}{3-3}$
Add/Subtract: $m=\frac{8}{0}$
Divide: m = undef

When we divide anything by zero, we will get undefined. Therefore, this would be a vertical line.

The National Highway Traffic Safety Administration reported the percentage of traffic accidents occurring each day of the week.

Zigmanuir [339]

Answer:

Hence,

Test statistic $X^{2}$ = 9.269.

p value = 0.148

Sunday= 15.23%, Monday= 12.62%, Tuesday= 13.10%, Wednesday=11.67%,

Thursday= 13.10%, Friday= 16.19%, Saturday= 18.09%.

Step-by-step explanation:

relative observed Expected Chi square

Category frequency(p) $O_{i}$ Ei=total*p $(O-E)^{2}$ $R^{2}_{i} =(O_{i} -E_{i} )^{2} /E_{i}$

1 0.142857143 64.0 60.00 16.00 0.267

2 0.142857143 53.0 60.00 49.00 0.817

3 0.142857143 55.0 60.00 25.00 0.417

4 0.142857143 49.0 60.00 121.00 2.017

5 0.142857143 55.0 60.00 25.00 0.417

6 0.142857143 68.0 60.00 64.00 1.067

7 0.142857143 76.0 60.00 256.00 4.267

Total 1.000 420 420 556 9.269

Test statistic $X^{2}$ = 9.269.

p value = 0.148 from excel: chidist(9.269,6)

Percentage %= Frequency of traffic occur on category x 100 / Total number of frequency given.

Category Percentage%

Sunday 15.23%

Monday 12.62%

Tuesday 13.10%

Wednesday 11.67%

Thursday 13.10%

Friday 16.19%

Saturday 18.09%
