Pls help

Karolina [17]

Answer:

D

Step-by-step explanation:

If we look at the right side of the equation we see that the y-intercept is 2, so we will place a point on (0,2).

Next, we look to see if the slope of the graph if positive or negetive, and to see what is the slope (2x).

Finally, we look at the inequality if it is greater than (>), less than (<), greater than or equal to (_>), or less than or equal to (<_).

*Note the following:

if < then the line is dotted and the shading will be under the line.

if > then the line is dotted and the shading will be above the line.

if <_ then the line is solid and the shading will be under the line.

if _> then the line is solid and the shading will be above the line.*

It is a lot of information if you look at it, but with practice it can be made easier.

If Javier has a car with a mass of 250,000 kg and it is acted upon with a force of 300 Newtons. What is the acceleration?

natima [27]

Answer:

The acceleration is 0.0012 meters/seconds²

Step-by-step explanation:

1. Let's review the information given to answer the question correctly:

Mass = 250,000 kg

Force = 300 Newtons

2. What is the acceleration?

Based on Newton's Second Law of Motion, let's recall that:

Force = Mass * Acceleration

Acceleration = Force/Mass

Replacing with the real values, we have:

Acceleration = 300/250,0000

Acceleration = 0.0012 meters/seconds² (we can't express acceleration using Newtons/kilograms as the unit).

Help please will mark brainless 25 points due today

harkovskaia [24]

here's the solution,

we know that, sum of measures of each interior angle of a triangle = 180°

Figure 1.

=》

$40 + 32 + 9x + 9 = 180$

=》

$81 + 9x = 180$

=》

$9x = 180 - 81$

=》

$x = \frac{99}{9}$

=》

$x = 11$

Figure 2. 

=》

$42 + 63 + 4x + 15 = 180$

=》

$120 + 4x = 180$

=》

$4x = 180 - 120$

=》

$4x = 60$

=》

$x = \frac{60}{4}$

=》

$x = 15$

Figure 3.

=》

$45 + 45 + 3x - 21 = 180$

=》

$3x + 69 = 180$

=》

$3x = 180 - 69$

=》

$3x = 111$

=》

$x = \frac{111}{3}$

=》

$x = 37$

Find the critical value from the Studentized range distribution for H0: μ1 = μ2 = μ3 = μ4 = μ5, with n = 35 at α = 0.01. Provide

Aleonysh [2.5K]

Answer:

t-value = 2.441

Step-by-step explanation:

Let's assume that this is a one-tailed test to calculate the critical value, the process is this:

Calculate alpha (α): α = 1 - (confidence level / 100) , but we already have this α=0.01
Find the critical probability (p*): p* = 1 - α/2 = 1-0.005=0.995
Then, the critical value would be shown as a t statistic, but for this we need:

degrees of freedom (df)= n-1=35-1=34

The critical t statistic (t*) or critical value is the t-value having degrees of freedom equal to 34 and a cumulative probability equal to 0.995.

From the attached table we can see:

t-value = 2.441
