Answer:

The root of the equation is x=2.  

Step-by-step explanation:

Given : Equation 3x+1=7

To find : Solve for x?

Solution :

Step 1 - Write the equation

3x+1=7

Step 2 - Subtract 1 both side,

3x+1-1=7-1

3x=6

Step 3 - Divide the equation by 3,

\frac{3x}{3}=\frac{6}{3}

x=2

Therefore, The root of the equation is x=2.

What is the measure of ∅?<br><br>A. 2.5 π radians<br>B. 2.5 radians<br>C. 4 radians<br>D. 5 radians​
natka813 [3]

Answer:

C. 4 radians

Step-by-step explanation:

20=\frac{\pi (Ctrl.Angle)(5)}{180}

Ctrl Angle = ∅

∅ = \frac{(20)(180)}{5\pi } =\frac{3600}{5\pi } =\frac{720}{\pi }

in radians:

∅ = \frac{720}{180} =4

Hope this helps

3. A researcher randomly selects a sample of 61 former student leaders from a list of graduates of UNCG who had participated in
Sophie [7]

Answer:

not statistically significant at ∝ = 0.05

Step-by-step explanation:

Sample size( n )  = 61

Average for student leader graduates to finish degree ( x') = 4.97 years

std = 1.23

Average for student body = 4.56 years

<u>Determine if the difference between the student leaders and the entire student population is statistically significant at alpha</u>

H0( null hypothesis ) : u = 4.56

Ha : u ≠ 4.56

using test statistic

test statistic ; t = ( x' - u ) / std√ n

                        = ( 4.97 - 4.56 ) / 1.23 √ 61

                        = 2.60

let ∝ = 0.05 , critical value = -2.60 + 2.60

Hence we wont fail to accept  H0

This shows that the difference between the student leaders and the entire student population is not statistically significant at ∝ = 0.05

7 + (2 + 6) 2 ÷ 4 ⋅ (1/2)^4<br><br> A: 23<br> B: 18<br> C: 9<br> D: 8
Drupady [299]

Answer:

D: 8

Step-by-step explanation:

7 + (2 + 6) ^2 ÷ 4 ⋅ (1/2)^4

According to PEMDAS

We to parentheses first

7 + (8)^ 2 ÷ 4 ⋅ (1/2)^4

Then we do exponents

7 + 64 ÷ 4 ⋅ (1/16)

The multiply and divide from left to right

7+64 ÷ 4 ⋅ (1/16)

7+16 ⋅ (1/16)

Then add and subtract from left to right

7+1

8
