Using descriptive statistics, you have found out that it takes an average of 40 minutes to complete a mid-term examination in IS

choli [55]

Answer:

b. exam completion time is negatively skewed

Step-by-step explanation:

A data distribution is said to be negatively skewed when <em>median</em> value of the distribution is higher than the <em>average</em> value of the distribution.

In this example

average mid-term completion time is 40 minutes

median mid-term completion time is 55 minutes.

thus median > mean, so the mid-term completion time is negatively skewed. Negatively skewed distributions are also called left-skewed.

A triangle has squares on its three sides as shown below. What is the value of x? Three squares having side lengths 3 cm, x cm,

Pani-rosa [81]

Answer:

The value of x is 5 centimeters.

Therefore, option 3 is correct.

Step-by-step explanation:

A triangle has three sides 3,x and 4 cms

Since the triangle is right angle triangle so, it will follow the Pythagoras theorem:

$hypotenuse^2=side^2+side^2$ (1)

We have been given three sides x,3 and 4

On substituting the values in (1) we get:

$x^2=3^2+4^2$

$x^2=9+25$

$\Rightarrow x=5$

Hence, the value of x is 5 centimeters.

Therefore, option 3 is correct.

Please look at the attachment for the figure.

Product A is a 8oz bottle of cough medicine that sells for $1.36. Product B is a 16oz bottle of medicine that costs 3.20 which p

Sauron [17]

Product A= 8oz = 1.36 x 2= 2.72. 16oz = 2.72

product B= 16oz= 3.20

so Product A has the lower unit price.

Write an equation of a parabola that opens to the left, has a vertex at the origin, and a focus at (–4, 0).

8_murik_8 [283]

Answer:

$y^{2}=-16x$

Step-by-step explanation:

we know that

The standard equation of a horizontal parabola is equal to

$(y-k)^{2}=4p(x-h)$

where

(h,k) is the vertex

(h+p,k) is the focus

In this problem we have

(h,k)=(0,0) ----> vertex at origin

(h+p,k)=(-4,0)

so

h+p=-4

p=-4

substitute the values

$(y-0)^{2}=4(-4)(x-0)$

$y^{2}=-16x$
