Answer:
(x, f(x)) = (1, 6), (2, 11), (3, 18), (4, 27)
Step-by-step explanation:
Each figure consists of two small squares and a square that has a side length of 1 more than the figure number. That is, ...
f(x) = (x +1)^2 +2
You can count the squares in figures 1-3. Figure 4 will be 2 more squares than 5^2 = 25, so will be 27 squares.
(x, f(x)) = (1, 6), (2, 11), (3, 18), (4, 27)
What's 2/5 divided by 4 ( simplest form)
Answers
Answer:
1/10
Step-by-step explanation:
[tex]\frac{2}{5} \div 4 = \frac{2}{5} * \frac{1}{4}[/tex]
we multiply by the reciprocal when we work with fractions and division.
Now you just multiply across.
Therefore, you have 2/20, which simplifies to 1/10.
A fraction is a part of a whole.
It is expressed as a quotient, in which the numerator is divided by the denominator.
The simplest form of 2/5 divided by 4 is 1/10.
What is a fraction?A fraction is a part of a whole.
It is expressed as a quotient, in which the numerator is divided by the denominator.
Example: 2/3, 5/7, 1/3
We have,
2/5 ÷ 4
= (2/5) / 4
= 2 / (4 x 5 )
We cancel the common factor from the numerator and denominator.
= 2 / (2 x 2 x 5)
= 1 / (2 x 5)
= 1 / 10
We see that there is no common factor to be canceled out from the numerator and the denominator.
= 1/ 10 is our simplest form.
Thus the simplest form of 2/5 divided by 4 is 1/10.

29+2x=x+24
Subtract both sides by 29
29+2x-29=x+24-29
2x=x-5
Subtract both sides by x
2x-x=x-5-x

correctly factor the expression 15a-6b+36 using the greatest common factors
Answers
Answer:
3 ( 5a - 2b + 12)
Step-by-step explanation:
15 = 3 * 5
6 = 2 * 3
36 = 2 * 2 * 3 * 3
GCF = 3
15a - 6b + 36 = (3* 5 * a) - (3 *2 * b) + (3 * 12)
= 3 ( 5a - 2b + 12)
Answer:
3 ( 5a - 2b + 12)
Step-by-step explanation:
15 = 3 * 5
6 = 2 * 3
36 = 2 * 2 * 3 * 3
GCF = 3
15a - 6b + 36 = (3* 5 * a) - (3 *2 * b) + (3 * 12)
= 3 ( 5a - 2b + 12)

dally should be equal to the equation 2y + 5z = 32. Sean's parents have decided to use both equations to determine the number
of hours Sean should study and relax What is an equivalent equation to the addition of Sean's mother's equation and Sean's father's
equation? Select all that apply.
Answers
Answer and explanation:
We add both equations to get a simultaneous equation
y+4z=16
2y+5z=32
We solve the equations using elimination method:
Multiply equation 1 by 5 and equation 2 by 4 to cancel out z
5y+20z=80
8y+20z=160
-3y=-80
Y=26.7
Substitute y=26.7 in equation 1
26.7+4z=16
4z=16-26.7
z= -2.67
y+z=26.7+(-2.67)= 24.03

The _________ of a hypothesis test is the probability (1minus beta) of rejecting a false null hypothesis.
Answers
Answer:
Power
Step-by-step explanation:
An hypothesis is usually formulated at the beginning of research, it is usually in line with the problem statement and gives the possible outcome.
An hypothesis is either accepted or rejected.
Power in hypothesis is the probability of rejecting null hypothesis when it is false. It helps in making a correct decision by rejecting the null hypothesis when it is not true.
power ranges between 0 to 1 when it is close to 1 it is said to be very strong and has the probability of rejecting a null hypothesis when it is not true.
Power helps to avoid a type II error in statistics.

What is the highest common factor?The Highest Common Factor (HCF) of two numbers is the highest possible number that is divisible by both numbers.
In other words, the highest common factor is the common factor between the two numbers but it should be the highest among all common factors.
As per the given,
Ramon has 27 tomato plants, 15 cucumber plants, and 6 basil plants.
Factors of 27 = 1, 3, 9, and 27.
Factors of 15 = 1, 3, 5 and 15
Factors of 6 = 1, 2, 3 and 6
The GCF of 27,15 and 6 is 3.
Thus, only three raws are possible.
Hence "The greatest number of rows that can be formed in the garden will be 3".
