Step-by-step explanation:
no it's not.....
........
Answer:
no
Step-by-step explanation:
there should always be even number of 0 if it wants to be a perfect square.
3 * 3 =9
30 * 30 =900. .......(2 0's)
300 * 300 = 9000...(4 0's and so on)
9000 does not meet this criteria so it isn't a perfect square.

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 decre
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

Step-by-step explanation:
A silo is a composite of a cylindrical tower with a cone for a roof. What is the volume of the silo if the radius of the base is 30 feet, the height of the roof is 12 feet, and the height of the entire silo is 60 feet?
147,026.5 ft
135,716.8 ft
180,955.7 ft
169,646.0 ft
Answer:
The volume of the silo is approximately 147,026.6 ft.³.
The most correct option is 147,026.5 ft.³
Step-by-step explanation:
The given dimensions of the silo are;
The shape of the silo = Composite figure of tower and roof
The shape of the tower = Cylindrical
The shape of the roof = Cone
The radius of the base of the silo, 'r' = 30 feet
The height of the cone roof of the silo, h₁ = 12 feet
The height of the entire silo = 60 feet
For the cone roof, we have;
The volume of a cone, V = 1/3 × Base area × Height
The volume of the cone roof, V₁ = 1/3×π·r² × h₁
∴ V₁ = 1/3 × π × (30 ft.)² × 12 ft. ≈ 11,309.7336 ft.³
For the cylindrical tower, we have;
The height of the entire silo = The height of the tower + The height of the roof
∴ The height of the tower = The height of the entire silo - The height of the roof
The height of the tower, h₂ = 60 ft. - 12 ft. = 48 ft.
The volume of a cylinder = Area of base × Height
The volume of the cylindrical tower, V₂ = π·r² × h₂
∴ V₂ = π × (30 ft.)² × 48 ft. ≈ 135,716.803 ft.³
The volume of the cylindrical tower, V₂ ≈ 135,716.803 ft.³
The volume of the (entire) silo, Vₙ = V₁ + V₂
∴ Vₙ = 11,309.7336 ft.³ + 135,716.803 ft.³ = 147,026.573 ft.³
The volume of the (entire) silo, Vₙ ≈ 147,026.6 ft.³.
Answer:
147,026.5 ft.³

Alan types at a rate of 30 words per minute. How many words does he type in 3 minutes? words
Answer:
90 words
Step-by-step explanation:
Based on the information we have already, we can assume Alan types the same amount of words per minute meaning, all we have to do here is multiply.
30 words per minute x 3 minutes = 90 words
The vertex of this parabola is at (-5, 4). Which of the following could be its
equation?
(-5, 4)
A. y* -(x + 5)2 - 4
B. y = -(x - 5)2 - 4
C. y = -(x - 5)2 + 4
D. y = -(x + 5)2 + 4
Answer:
D
Step-by-step explanation:
Because the x-coordinate of the vertex is negative, only A or D could be the correct equation for this parabola. D is correct because its constant (4) matches the y-coordinate of the vertex (-5, 4).
Answer:
y = -(x + 5)2 + 4

Ratio tables what’s the missing ratio
Answer:
16
Step-by-step explanation:
To solve we must first find what the given ratios equal
8/5 = 1.6
40/25 = 1.6
48/30 = 1.6
this means that x/10 = 1.6
To find x... multiply both sides of this equation my 10 to get x alone
x=1.6×10
x=16

Answer:
g. 9−7+{−2+3−[4−2+(3+2)−7]+8} = 11
h. – {- [ (14 - 7) - (32 - 41)]} = + 16
i. – [(-8 + 3) + (- 21 – 12)] = + 38
j. 500 – {( 6 – 18 + 4 + 3 + 16 - 10 – 2) – 5 } = 506
k. (9 + 7 – 2 + 4) – ( 9 -12 ) =21
Step-by-step explanation:
These questions are solved by solving the small brackets, then square brackets and then the curly brackets.
g. 9−7+{−2+3−[4−2+(3+2)−7]+8}
= 9−7+{−2+3−[4−2+(5)−7]+8} Solving inner small brackets
= 9−7+{−2+3−[9−2−7]+8} Solving outer square brackets
= 9−7+{−2+3−0 +8} Solving curly brackets
=9−7+{9} Adding like terms ( adding positive terms)
= 18-7
= 11
h. – {- [ (14 - 7) - (32 - 41)]}
= – {- [ (14 - 7) - (-9)]} Solving inner small brackets
= – {- [ (7) +9]} Solving inner small brackets
= – {- [ 16 ]} Solving outer square brackets
= – {- 16 } Solving curly brackets
= + 16 (-*-= +)
i. – [(-8 + 3) + (- 21 – 12)]
= – [(-8 + 3) + (- 33)] Solving inner small brackets
= – [(-5 - 33)] Solving inner small brackets
=– [( - 38 )] Solving outer square brackets
= + 38 (-*-= +)
j. 500 – {( 6 – 18 + 4 + 3 + 16 - 10 – 2) – 5 }
= 500 – {( 6 + 4 + 3 + 16 – 18 -10 – 2) – 5 } Solving inner small brackets
= 500 – {( 29 – 30) – 5 } Solving inner small brackets
= 500 – {( – 1) – 5 } Solving inner small brackets
= 500 – { – 6} Solving curly brackets
= 500 + 6 (-*-= +)
= 506
k. (9 + 7 – 2 + 4) – ( 9 -12 )
= (9 + 7 + 4– 2 ) – ( -3 ) Solving inner small brackets
= (20 – 2 ) – ( -3 ) Solving inner small brackets
= (18 ) – ( -3 ) (-*-= +)
= 18 +3

If you answer I will mark you Brainliest!
Answer:
divide the figure into two parts.
area of triangle = 1/2×base×height
area of triangle = 1/2×3×3
area pf triangle = 4.5 units²
area of square = side²
area of square = 3²
area of square = 9unit²
Answer:
The figure is made up of a square and a triangle.
We will find both of their areas separately and then combining them will give us the required area.
Area of the triangle : ½ × base × height
= ½ × 3 × 3
= ½ × 9
= 4.5 units²
Area of the square : (side)²
= 3²
= 9 units²
Now, required area = (4.5 + 9) units²
= 13.5 units²
