Answer:

So the rectangle's width = 8 m

Step-by-step explanation:

Given:

Length = 14 m

Perimeter= 44 m

To Find:

Width = ?

Solution:

We are given the length and perimeter of a rectangle and have to find the value of width. This we can find by the formula of perimeter of rectangle

So the formula for it is

Perimeter = 2( length + width)

Putting the values

44 = 2(14+width)

it becomes

44 = 28 + 2*width

subtracting 28 from both sides

44-28 = 28 -28 + 2*width

16 = 2*width

Dividing both sides by 2

16/2 = width

8 = width

width = 8 m

Javier volunteers in community events each month. He does not do more than five events in a month. He attends exactly five event

mezya [45]

Answer:

The probability of Javier volunteers for less than three a month is 25%

Step-by-step explanation:

According to the questions,

The probability of Javier to attend exactly 5 events :-

P ( x = 5 ) = 25% = $\frac{1}{4}$

The probability of Javier to attend exactly 4 events :-

P ( x = 4 ) = $\frac{1}{4}$

The probability of Javier to attend exactly 3 events :-

P ( x = 3 ) = $\frac{1}{4}$

The probability of Javier to attend exactly 2 events :-

P ( x = 2 ) = $\frac{3}{20}$

The probability of Javier to attend exactly 1 events :-

P ( x = 1 ) = $\frac{1}{20}$

The probability of Javier to attend no events :-

P ( x = 0 ) = $\frac{1}{20}$

Now we have to calculate the probability of Javier volunteers for less than three P ( x < 3 ).

P ( x < 3 ) = P ( x = 0 ) + P ( x = 1 ) + P ( x = 2 )

P ( x < 3 ) = $\frac{1}{20} + \frac{1}{20} + \frac{3}{20}$ $= \frac{1 + 1 + 3}{20}$ = $\frac{5}{20}$ = $\frac{1}{4}$ = 0.25 = 25 %.

nordsb [41]

Answer: Stratified sampling

Step-by-step explanation:

Stratified sampling is a random sampling method in which the population is divided into non-coinciding groups are called strata and a sample is picked out by some design within each stratum.

Given: A researcher wants to survey people from different age groups to analyze voting patterns.

Thus he will make different groups according to different ages to analyze voting patterns that are called stratum.

Thus, Stratified sampling best accomplish this goal.

ALGEBRA HELP!! Write an exponential function represented by the table.

marysya [2.9K]

Answer:

y=-50*0.2^x

Step-by-step explanation:

the formula for an exponential function is:

y=a*b^x

what do we multiply -50 by to get -10?

-50x=-10

x=-10/-50

x=1/5

x=2/10

x=0.2

This initial value here is -50, it is the first in the table

y=-50*0.2^x
