Answer:
x² - 6x + 9
Step-by-step explanation:
(a - b)² =a² - 2ab + b²
a = x and b = 3
(x - 3)² = x² - 2*x*3 + 3²
= x² - 6x + 9
Answer:

6, 13, 20, 27 ...
Answer:
349
Step-by-step explanation:
[tex]a_{n} = a_{1} + (n - 1)d[/tex]
n = 50 [tex]a_{1}[/tex] = 6 d = 13 - 6 = 7
[tex]a_{50}[/tex] = 6 + (50 - 1)(7)
= 6 + 49(7)
= 6 + 343
= 349
Answer:
formula as mentioned above...
Step-by-step explanation:
N=50,a=6,d=difference between no. that is 8
so,
x50=6+8(50-1)
x50=6+8(49)
x50=6+392=398 Answer

A researcher wants to see if a kelp extract helps prevent frost damage on tomato plants. One hundred tomato plants in individual containers are randomly assigned to two different groups. Plants in both groups are treated identically, except that the plants in group 1 are sprayed weekly with a kelp extract, while the plants in group 2 are not. After the first frost, 12 of the 50 plants in group 1 exhibited damage and 18 of the 50 plants in group 2 showed damage. Let p1 be the actual proportion of all tomato plants of this variety that would experience damage under the kelp treatment, and let p2 be the actual proportion of all tomato plants of this variety that would experience damage under the no-kelp treatment.

Complete question is;
A researcher wants to see if a kelp extract helps prevent frost damage on tomato plants. One hundred tomato plants in individual containers are randomly assigned to two different groups. Plants in both groups are treated identically, except that the plants in group 1 are sprayed weekly with a kelp extract, while the plants in group 2 are not. After the first frost, 12 of the 50 plants in group 1 exhibited damage and 18 of the 50 plants in group 2 showed damage. Let p1 be the actual proportion of all tomato plants of this variety that would experience damage under the kelp treatment, and let p2 be the actual proportion of all tomato plants of this variety that would experience damage under the no-kelp treatment. Is there evidence of a decrease in the proportion of
tomatoes suffering frost damage for tomatoes sprayed with kelp extract? To determine
this, yo u test the hypotheses H0: p1 = p2, Ha: p1 < p2. The p - value of your test is
A) greater than 0.10.
B) between 0.05 and 0.10.
C) between 0.01 and 0.05.
D)between 0.001 and 0.01.
E) below 0.001.
Answer:
B) between 0.05 and 0.10.
Step-by-step explanation:
We are given;
Number of plants in group that exhibited damage = 12
Number of group 1 plants; n₁ = 50
Number of plants in group 2 that exhibited damage = 18
Number of group 2 plants; n₂ = 50
Proportion of plants in group 1 that exhibited damage; p₁^ = 12/50 = 0.24
Proportion of plants in group 2 that exhibited damage; p₂^ = 18/50 = 0.36
Pooled proportion; p¯ = (12 + 18)/(50 + 50) = 0.3
q¯ = 1 - p¯
q¯ = 1 - 0.3 = 0.7
Z-score will be;
z = ((p₁^ - p₂^) - 0)/√((p¯•q¯)×((1/n₁) + (1/n₂))
Plugging in the relevant values;
z = (0.24 - 0.36)/√((0.3 × 0.7) × ((1/50) + (1/50))
z = -0.12/0.092
z = -1.3
From z-distribution table attached, we have;
p-value = 0.0968

Can someone plz help
Answer:
47.3
Step-by-step explanation:
A triangles angles add up to 180 degrees
At 42.7 and 90 and you get 132.7
Subtract 132.7 from 180 and you get 47.3 degrees.
Answer:
A. 47.3°
Step-by-step explanation:
The sum of all the angles in a triangle equals 180°, so we need to subtract 42.7° and 90° from 180° to get ∠N.
180° - 90° - 42.7° = 47.3°
∠N = 47.3°

are given the sets A = (even numbers less than 10) and B = (multiples of 3 greater than 3) A:name the communities A and B B:describe the community A n B
Answer:
A n B = {6}
Step-by-step explanation:
Given he sets A = (even numbers less than 10) and B = (multiples of 3 greater than 3)
A = {2, 4, 6, 8}
B = {3, 6, 9, 12, 15...}
A n B includes the numbers are are common to both sets i.e number that we can find in both A and B.
From the set given, we can see that the only number that exists in both set is 6, hence;
A n B = {6}

Answer:
[tex]6\frac{2}{3}[/tex]
Step-by-step explanation:
When one multiplies fractions, one must first ensure that both fractions are in the improper fraction format. This can be done by multiplying the number next to the fraction by the denominator of the fraction then adding the result to the numerator,
[tex]8\frac{1}{3} * \frac{4}{5}\\\\= \frac{24+1}{3} * \frac{4}{5}\\\\= \frac{25}{3}*\frac{4}{5}[/tex]
Now cross simplify, remove factors that the numerator and denominator have in common,
[tex]\frac{5}{3}*\frac{4}{1}[/tex]
Finally, multiply, multiply the numerator of the first fraction with the numerator of the second fraction, and the denominator of the first fraction with the denomaintor of the second fraction.
[tex]\frac{20}{3}[/tex]
Convert the result to a mixed number. This can be done by dividing the numerator by the denominator, write the result to the left of the fraction, and the remainder as the numerator,
[tex]6\frac{2}{3}[/tex]

what would the volume be if the diameter is 6 and the height is 8 of a cylinder in inches
Plss show all work step by step
Answer:
72π
Step-by-step explanation:
Please see the attached image. r is the radius and h is the height.
The radius is half the diameter, so it is 6/2=3.
The height is given, 8.
Knowing the radius is 3 and the height is 8, all we need to do is plug it into the formula.
Volume=π3^2*8
=72π

If laura bought 2.1 pounds of apples is the price per pound of apples greater than or less than $1? How can you tell?
Answer:
The price per pound of apples is greater than $1.
Step-by-step explanation:
Three coworkers decided to buy fruit to share at lunchtime. Antonii spent $1.47 on bananas. Laura spent $2.88 on apples. Suzanne spent $2.85 on oranges. If Laura bought 2.1 pounds of apples, is the price per pound of apples greater than or less than $1? how can you tell?
To find the price of apples per pound, we need to divide the total amount paid by Laura ($2.88) with the total pounds of apples (2.1 pounds) bought.
Price of apples per pound = $2.88/2.1
price of apples per pound= $1.37142857
Since the price of apples per pound is $1.37, therefore, the price per pound of apples is greater than $1.
We can simply tell that the price per pound of apples is greater than $1 because 2.88 is greater than 2.1. So when we will divide 2.88 by 2.1, then we will get a number greater than 1.
(hope this helps can i plz have brainlist :D hehe)
The cost of one pound of apple is $1.37.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, Laura spent $2.88 on apples.
If Laura bought 2.1 pounds of apples
Cost of 1 pound apple =2.88/2.1
= $1.37
1.37>1
Therefore, the cost of one pound of apple is $1.37.
