The correct statement is,
⇒ The finding is significant at both α = 0.05 and α = 0.01.
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Given that;
For a hypothesis test of H₀, p = 0.35 against the alternative,
And, Hₐ: p > 0.35, the z test statistic is found to be 2.45.
Now, We get;
P(z < 2.45) = 0.9929
Hence, Significant is,
⇒ 1 - 0.9929 = 0.0071
Thus, Significant at both 0.05 and 0.01 because both are greater than 0.0071.
So, The correct statement is,
⇒ The finding is significant at both α = 0.05 and α = 0.01.

Step-by-step explanation:
The lines represent the lines of symmetry where the image can be reflected upon. Hence it is reflectional.
The dot in the middle of the image tells us that the image can be rotated about the dot to produce the exact same image. Hence it is rotational.
The answer is both rotational and reflectional.
Answer:
I broke it to phrases. Make sure to read both.
It is rotational symmetry. This is because rotational symmetry means it is able to be rotated, and looks the same. This is true with this figure. The lines demonstrate that it is an equal dimensioned 2D shape.
It is ALSO reflection symmetry because this means it can be split through the center and looks exactly the same, as if it was a reflection. This is true here too because it has the same amount of lines split through the same angle on each side making it equal. You can also see a line already going through the shape, and as you can see if you look at see side it looks equal, like a reflection.
The answer is D.

Bill Ding plans to build a new hardware store. He buys a rectangular lot that is 50 ft by 200 ft, the 50-ft dimension being along the street. The store is to have 4000 ft2 of floor space. Construction costs $100 per linear foot for the part of the store along the street and only $80 per linear foot for the parts along the sides and back. To what dimensions should Bill build the store to minimize construction costs
Answer:
Length a = 59.62
Width b = 67.09
Cost = $10,734.4
Step-by-step explanation:
Solution:
Let a be the length and b be the width.
Area of the rectangle = a x b
a x b = 4000
Cost of the construction:
Cost = 100a + 80(a + 2b)
Cost = 100a + 80a + 160b
Cost = 180a + 160b Equation of the Cost of the construction.
Now, we need a and b to calculate the minimum cost required to build a lot.
From the area = a x b
we have,
a x b = 4000
b = 4000/a
Putting this equation into the cost of the construction.
We get:
Cost = 180a + 160 x (4000/a)
Cost = 180a + 640000/a
Differentiating with respect to a, we get
[tex]C^{'}[/tex] = 180 - 640000/[tex]a^{2}[/tex]
Putting [tex]C^{'}[/tex] = 0
180 - 640000/[tex]a^{2}[/tex] = 0
Taking LCM
180[tex]a^{2}[/tex] - 640000 = 0
Solving for a
180[tex]a^{2}[/tex] = 640000
[tex]a^{2}[/tex] = 640000/180
[tex]a^{2}[/tex] = 3555.55
Taking square root
a = 59.62
As we know,
b = 4000/a
putting the minimum value of a = 59.62
b = 4000/59.62
b = 67.09
So, now we have both the dimensions a and b
Putting the values of a and b we will get the cost of the construction.
Cost = 180a + 160b
Cost = 180(59.62) + 160(67.09)
Cost = $10,734.4
Hence, $10,734.4 will be the minimum cost of the construction for Bill Ding.

To solve the problem we must know about the volume.
What is Volume?Volume is described as the total amount of space taken by an object. It is a scalar quantity and it is 3 dimensional.
The amount of cereal inside a cereal box has volume.
As we know that the cereal box has space inside to hold something therefore, the cereals or something can be put inside this that will make the space inside the box. Also, the box has length, breadth, and height, therefore, it is 3 dimensional.

Your balance sheet shows $6,400 worth of inventory in hair products. Items are recorded in inventory at cost, and the average cost per unit is $2.43. How many units of hair products do you have ?
Answer:
Units of hair products = 2634 units
Step-by-step explanation:
Given that:
Worth of products in the inventory = $6400
Average cost per unit = $2.43
Number of units = [tex]\frac{Total\ worth}{Per\ unit\ cost}[/tex]
Number of units = [tex]\frac{6400}{2.43}[/tex]
Number of units = 2633.73
Rounding off to nearest whole number = 2634 units

The answer is B.
For A. its not true, the two triangles show that XW and RS are equivalent.
For C. its not true, the two triangles show that m<R is equal to m<X, not m<R=m<Y.
For D, its not true, the two triangles show that m<X is equal to m<R, not m<R=m<Y.
The two triangles show SSA, which prove that the triangle is equivalent. So, then, corresponding sides are considered equivalent. As a result, you can assume that ST=WY.
