1.0 and 1/1

Step-by-step explanation:

Answer:

decimal : 1

fraction :  1

Step-by-step explanation:

Percentage is always out of 100

100%

to convert from percentage to a fraction, you just put 100 and the bottom of that number;

[tex]\frac{100}{100}[/tex] ; this is equal to 1

to convert percentages to a decimal, we divide by 100;

100 ÷ 100 = 1

Answer:

B) Cluster Sampling.

Step-by-step explanation:

Cluster sampling refers to a methodology for probability sampling, in which researchers split the populace into several study groups or one can say clusters. And after this investigators pick random groups for collecting and analyzing data, using a systematic random or simple random sampling technique, depending on the research subject. As per the question, instead of 200 grids selected a cluster of 30 grids for the research and therefore it is a classic of cluster sampling.

Answer:

Um its 2.83

Step-by-step explanation:

This is a 5th grade quesion

The value of each digit in a number is known as the place value. The 5 in 350. The value of √8 rounded off to the nearest hundredth is 2.83.

The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.

Identification of the place value of a digit in a number:

Given √8 whose approximate values to its nearest hundredth can be written as,

The value of √8 = 2.8284271247

Round 2.8284271247 to its nearest hundredth.

We have,

2.8(2)84271247

2 is in the hundredth place.

We will round 284  to its nearest hundredth.

It will round to either 200 or 300.

Since it is 284 is more than 250 we will round to 300.

Therefore, 2.8300 is our answer.

Thus, the value of √8 rounded off to the nearest hundredth is 2.83.

Answer:

y = 5/2x + 5

y = 5/2x - 9.5

Step-by-step explanation:

We need to solve for the y in the expresion of 2x + 5y = 25

[tex]2x + 5y = 25\\y = (25 - 2x)/5 \\y = 5 - 2/5x[/tex]

now we re-arrenge the factors in the form y = ax + b

y = -2/5x + 5

we reverse "a"

y = 5/2 + a

And now, we use a point in the other formula to solve for a:

original line:

y = 5 - 2/5x

X = 0 then Y = 5

now we solve for the general equation of the perpendicular equation:

[tex]y - y_1 = m ( x - x_1)[/tex]

[tex]y - 5 = 5/2 (x - 0)\\y = 5/2x + 5[/tex]

If we use a different point we get a different formula:

original line:

y = 5 - 2/5x

X = 5 then Y = 3

[tex]y - 3 = \frac{5}{2}(x - 5)\\y - 3 = \frac{5}{2}x -12.5 \\y = \frac{5}{2}x - 9.5[/tex]

ANSWER 32

(3p-6) is next to the right angle so I assume it is = to 90 degrees

(3p-6)=90 also means 3p=90+6 Which is 3p = 96

96/3 is 32

p = 32

for proof do

3 times 32 minus 6 and see if it = 90

d−14=34 shows that when we add sold drawing we get the total drawings

Step-by-step explanation:

We have been given that Rosa brought d drawings to an art show.

After selling 14 of them, she had 34 left.

We have to form a equation such that when we add 14 in 34 we get the total of drawings.

d-14=34d−14=34 (1)

Equation (1) shows that when we add sold drawing we get the total drawings

Answer:

d-14=34. 34+14=48. 48-14=34 which is our total

Answer:

87°

Step-by-step explanation:

if an angle is complementary that means that equals 90°.

and we know one part of the angles, so then we take 90° - 3° and we get 87°.

Answer:

The measure of its complementary angle is 87°

Step-by-step explanation:

We know this because the sum of two complementary angles is always equal to 90°, so:

90 - 3 = 87

Therefore, your final answer will be 87°
