The answer would be 15 because half of 10 is 5 so you just have to do that to 30, half of 30 is 15

A farmer plants a new type of corn and wants to quickly determine the yield, or total number of ears of corn, for the
miss Akunina [59]

Answer:

The statement which is not true about the sample is;

The sample of 10 plants was a census of the corn plants

Step-by-step explanation:

The statement out of the given statements which is not true about the sample is "The sample of 10 plants was a census of the corn plants"

The 10 unique number corn which the farmer randomly selects of which he then count the number of ears in the corn and multiply by 100 so as to quickly arrive at an estimate of the total number of ears of corn for the crop, without individually counting the ears on each plant from the 100 plants

A census is a counting and individual enumeration procedure to collect and record characteristic information and details of the all the members that make up a given population

Therefore, the farmer is finding an estimate of the number of ears of in the plants rather than taking a census of the ears of corn on each plants in the population of 100 plants

Where do the lines intersect?
storchak [24]
They are intersecting at 0,0.
One square on that chart is 2 units.
You can see this since it goes -10 then skips one then goes to -6.
The one in between is -8.
On every side of the intersection there is a 2 or -2.
2 - 2 or -2 + 2, depending if it's positive or negative, is 0.
So the lines are intersecting at 0,0.
Hope this helps! :)

Help!!
Xelga [282]

Answer:

D. 63%

Step-by-step explanation:

the white marble was picked out 41 of the 65 times, so 41/65

divide 41 by 65 in your calculator and you get .6307

then multiply it by 100 because it asked for a percentage and you get 63%

Solve for x using the correct order operations
Mice21 [21]

Answer:

B: x = -12

Step-by-step explanation:

12 - (3 × 2)^2 + 4 × 3

Use PEMDAS, meaning solve what's in the parentheses first (P stands for parentheses)

12 - (6)^2 + 4 × 3

We get 6 because 3 × 2 = 6

Next step is solve any exponents (E for exponents)

12 - 36 + 4 × 3

We get 36 because 6 × 6 = 36 (the exponent was 2 meaning multiply the same number, 6, twice: 6 × 6)

Now we move on to multiplication and division (M for multiplication and D for division)

These are interchangable in that either can go first depending on its location in the equation

However, since there is no division in this problem we automatically skip to multiplication

12 - 36 + 12

We answered 12 because 4 × 3 = 12

Our last steps in PEMDAS are addition and subtraction (A for addition and S for subtraction)

These are also interchangable, but both are apparent in this problem

Now it depends on location

Whichever sign (addition or subtraction) is first in accordance from left to right is where we start first)

Subtraction is first

-24 + 12

Now we add -24 + 12

-12
