Answer:

x<-4

Step-by-step explanation:

There is an open circle where -4 is, so the maximum would be -5. There would be no minimum, so you can say that x is less than -4.

Answer:

x<-4

Step-by-step explanation:

The arrow shows an open circle around -4 meaning it's not equal to -4. And we see the arrow going left, meaning x<-4.

Hope this helps :^)

A college football coach has decided to recruit only the heaviest 15% of high school football players. He knows that high school

Alla [95]

Answer:

The coach should start recruiting players with weight 269.55 pounds or more.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 225 pounds

Standard Deviation, σ = 43 pounds

We are given that the distribution of weights is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

We have to find the value of x such that the probability is 0.15

$P( X > x) = P( z > \displaystyle\frac{x - 225}{43})=0.15$

$= 1 -P( z \leq \displaystyle\frac{x - 225}{43})=0.15$

$=P( z \leq \displaystyle\frac{x - 225}{43})=0.85$

Calculation the value from standard normal z table, we have,

$P(z < 1.036) = 0.85$

$\displaystyle\frac{x - 225}{43} = 1.036\\\\x = 269.548 \approx 269.55$

Thus, the coach should start recruiting players with weight 269.55 pounds or more.

What does this equal tox= -9

Len [333]

I'm guessing you mean which equation Equals -9

In each equation you are needing to get rid of X so you divide on both sides

A) -45=5x

-45/5=x
-9=x

and I double checked to make sure nothing else equaled -9 so Your answer Is A

Hope this helped!

While pushing a shovel into the ground with a force of 555 newtons ant an angle of 44 ∘ 44 ∘ to the ground. Find the magnitudes

Nataly [62]

The Horizontal component is 554.889N and the vertical component is

9.8235 Newton

<h3>Resolution of Forces</h3>

Given Data

Force = 555 Newton

Angle of Applied force = 44°

Fx = Horizontal component of the applied force

Fy = the vertical component of the applied force

Resolving the vertical force

Fy = 555 sin44°

Fy = 555 *0.01770

Fy = 9.8235 Newton

Resolving the horizontal force

Fx = 555 cos 44°

Fx = 555 *0.9998

Fx = 554.889 Newton
