Help needed I need the answer with work shown for the graphs

andreyandreev [35.5K]

top left: speed = 2.7 miles per hour = 2.7 MPH

top right: speed = 0 miles per hour = 0 MPH

bottom left: speed = 4 miles per hour = 4 mi/h

bottom right: speed = 2 miles per hour = 2 mi/h

and so, the fastest is bottom left. And pay attention in class! i'm in highschool and Iearned this in 6th grade!

Step-by-step explanation:

key: speed= distance/time

distance= speedxtime

time=distance/speed

top left: 8/3= 2.66667 MPH= 2.7 MPH

top right: 0/8= 0 MPH= 0 MPH

bottom left: 8/2= 4 MPH= 4 MPH

bottom right: 8/4= 2 MPH= 2 MPH

The probabilities can be calculated using an online calculator or tables, depending on which is more readily available.

QUESTION A

$P(Z>1.48)$

Using calculators, the probability will be:

$P(Z\gt1.48)=0.069$

QUESTION B

$P(Z\leq1.94)$

Using calculators, the probability will be:

$P(Z\leq1.94)=0.974$

QUESTION C

$P(-0.76Using calculators, the probability will be:[tex]P(-0.76\lt Z\lt2.05)=0.756$

1. A 30 ft. ladder is leaning against a building. The ladder reaches the bottom of a window that is located 15 ft. above the gro

____ [38]

Answer: 30°

Step-by-step explanation:

1. You know that:

- The length of the ladder is 30 feet.

- The window is located 15 feet above the ground.

2. Then, you can draw a right triangle as the one shown in the figure attached. So, you can calculate the angle asked as following:

$sin^{-1}\alpha=\frac{opposite}{hypotenuse}$

Where:

α: the angle of the ladder with the ground.

opposite=15 feet

hypotenuse=30 feet

3. When you substitute values, you obtain:

$sin^{-1}\alpha=\frac{15}{30}$

$\alpha=30$ °
