Answer:

Because if you think about it , 5×3 is 15 so you divide 15 by 3 which gives you 5 then you replace 3 with a 1

Step-by-step explanation:

3 (5x +1 )

Answer is :

(15x)+3

Reasoning: In PEMDAS, multiplication/ division (left to right) comes before add/ subtract (left and right) , meaning it will only matter IF we put x+3 in parenthesis.

Answer:

About 220 minutes.

What you have to do is divide 17 by 12 and multiply it by 155. After that, round the decimal up since the decimal part still counts as time.

Use technology and the given confidence level and sample data to find the confidence interval for the population mean mu. Assume

Sphinxa [80]

Answer: (1.55, 6.45)

Step-by-step explanation:

The confidence interval for population mean is given by :-

$\overline\ {x}\pm\ z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$

Given : Significance level : $\alpha: 1-0.99=0.01$

Critical value : $z_{\alpha/2}=2.576$

Sample size : n=41

Sample mean : $\overline{x}=4.0\text{ kg}$

Standard deviation : $\sigma=6.1\text{ kg}$

Then, 99% confidence interval for population mean will be :_

$4\pm\ (2.576)\dfrac{6.1}{\sqrt{41}}\\\\\approx4\pm2.45\\\\=(4-2.45, 4+2.45)=(1.55, 6.45)$

Two parallel lines are crossed by a transversal.

patriot [66]

Answer:

C. $m=102$

Step-by-step explanation:

We have been given an image of two parallel lines crossed by a transversal. We are asked to find the measure of m.

We can see that angle that measure 78 degrees and angle m are consecutive interior angles.

Since we know that consecutive interior angles are supplementary, so we can set an equation to find the measure of m as:

$78^{\circ}+m^{\circ}=180^{\circ}$

$78^{\circ}-78^{\circ}+m^{\circ}=180^{\circ}-78^{\circ}$

$m^{\circ}=102^{\circ}$

Therefore, the value of m is 102 and option C is the correct choice.
