The value of u is -144

Solution:

Given that,

$-24 = u \div 6$

We have to solve for "u"

From given,

$-24 = u \div 6$

Convert the division problem into multiplication, by changing the division sign to multiplication sign. Then invert the number to right of division sign

Thus we get,

$-24 = u \times \frac{1}{6}\\\\\frac{u}{6} = -24$

Isolate for u

$u = -24 \times 6\\\\On\ multiplying\ both\ we\ get\\\\u = -144$

Thus the value of u is -144

A rhombus, which is a quadrilateral with 4 equal sides, is plotted on the coordinate plane. The coordinates of the vertices are:

vova2212 [387]

Answer:

Each side of the Rhombus is 5 units

Step-by-step explanation:

Since the sides of a rhombus area all equal in length;

Then, the length of a side is enough to get the lengths of the other sides

Mathematically, finding the distance between two points out of what we are given will be enough to get the measure of one of the side of the rhombus

We apply the distance formula appropriately to get the distance between the side of the Rhombus

D = √(x2-x1)^2 + (y2-y1)^2

let us use the points (-1,0) and (4,0)

D = √(4 + 1)^2 + (0-0)^2

D = √25

D = 5

A study of 1000 randomly selected flights of a major airline showed that 769 of the flights arrived on time. What is the probabi

Anni [7]

Answer:

There are 23.1% probability of flights getting delayed.

Step-by-step explanation:

Given:

Number of samples of flights selected = 1000

Number of flights arrived on time = 769

We need to find the probability of flight being delayed.

Solution:

Now we will first find the number of flights which are delayed.

number of flights which are delayed can be calculated by subtracting Number of flights arrived on time from Number of samples of flights selected.

framing in equation form we get;

number of flights which are delayed = $1000-769 =231$

Now we will find the probability of flight being delayed.

probability of flight being delayed can be calculated by dividing number of flights which are delayed from the Number of samples of flights selected and then multiply by 100.

framing in equation form we get;

probability of flight being delayed = $\frac{231}{1000}\times 100 = 23.1\%$
