How would you describe the shape of the distribution of the data? How is it skewed?

Answer:

the normal distribution is a symmetric distribution with no skew. ... A left-skewed distribution has a long left tail. Left-skewed distributions are also called negatively-skewed distributions. That's because there is a long tail in the negative direction on the number line.

A rock is thrown up from the ground at a velocity of 84 feet per second. The formula h = -16t2 + 84t gives the rock's height in

kenny6666 [7]

Answer:

h = 110.24 m

Step-by-step explanation:

It is given that,

A rock is thrown up from the ground at a velocity of 84 feet per second. The formula $h = -16t^2 + 84t$ gives the rock's height in feet after t second.

We need to find the maximum height of the rock. For maximum height put $\dfrac{dh}{dt}=0$

So,

$\dfrac{d( -16t^2 + 84t)}{dt}=0\\\\-32t+84=0\\\\t=\dfrac{84}{32}\\\\t=2.62\ s$

Put t = 2.62 s in the equation of height. So,

$h = -16(2.62)^2 + 84(2.62)\\\\h=110.24\ m$

So, the maximum height of the rock is 110.24 m.

Answer:

Height of the cliff = 13.66 m

Step-by-step explanation:

Let the height of the cliff is 'x' m and distance between the base of the cliff and the boat is 'y' m.

From right triangle AOC,

tan 30° = $\frac{\text{Opposite triangle}}{\text{Adjacent side}}$

$\frac{1}{\sqrt{3}}=\frac{x}{y}$

y = $x\sqrt{3}$ ------(1)

From right angle triangle BOC,

tan 45° = $\frac{x}{y-10}$

$1=\frac{x}{y-10}$

x = y - 10

y = x + 10 -------(2)

From equations (1) and (2),

$x\sqrt{3}=x+10$

$x(\sqrt{3}-1)=10$

$x=\frac{10}{\sqrt{3}-1 }$

x = 13.66 m

Therefore, height of the cliff is 13.66 m.

Use the figure below to answer questions 10-11.

Anton [14]

The two marked angles are complementary angles. This means that the angles are equal.

Hence, X + 1 = 2X - 3.

By rearranging, X = 4.

The map uses a scale 1 inch = 880 ft. On the map, How many inches represent 2 miles?

andrew-mc [135]

Answer:

$12\ inches$

Step-by-step explanation:

<u>Step 1: Determine how many ft are in 2 miles</u>

$1\ mile = 5280\ ft$

$2\ miles = 5280\ ft * 2$

$2\ miles = 10560\ ft$

<u>Step 2: Determine how many 880 ft's are in 10560 ft</u>

$10560\ ft / 880\ ft$

$12$

Answer: $12\ inches$
