To find the value of z such that 0.11 of the area lies to the right of z, use the standard normal probability table. The value of z is approximately 1.96.
To find the value of z such that 0.11 of the area lies to the right of z, we can use the standard normal probability table. The area to the right of z is equal to 1 minus the area to the left of z.
Using the information given, the area to the left of z that corresponds to a value of 0.025 is 0.975. The area to the left of 1.96, which can be found using the standard normal probability table, is 0.975.
Therefore, the value of z is approximately 1.96.

Answer:
If Connor makes x dollars in sales, he will make 0.05x + 300 that week.
He makes $408.75 in a week if he makes $2175 in sales.
Step-by-step explanation:
y = 0.05x + 300
y = 0.05(2175) + 300
y = 408.75

Answer:
Step-by-step explanation:
Coordinates of points A and C are (-8, 6) and (2, 5).
If a point B intersects the segment AB in the ratio of 2 : 5
Then coordinates of the point B will be,
x =
and y =
where and are the coordinates of the extreme end of the segment and a point divides the segment in the ratio of m : n.
For the coordinates of point B,
x =
=
y =
=
Therefore, coordinates of pint B will be,
The coordinates of B on segment AC such that AB=2/5AC are given by line segment division theorem as ((2x2 + 5x1) / 7 , (2y2 + 5y1)/ 7), where A is (x1, y1) and C is (x2, y2).
The question is asking for the coordinates of point B on line segment AC such that the length of AB is 2/5 times the length of AC.
Since we don't have any specific coordinates for points A, B and C, we can't determine exact coordinates for point B. However, we can describe how to find B based on given points A and C.
If A and C have coordinates (x1, y1) and (x2, y2), respectively, then the coordinates of B can be found using the theorem of line segment division. This theorem says that the coordinates of the point dividing a line segment in the ratio m:n are given by:
((mx2 + nx1) / (m+n) , (my2 + ny1)/ (m+n))
Given the ratio is 2:5, m is 2 and n is 5, substitute the values into the formula:
((2x2 + 5x1) / (2+5) , (2y2 + 5y1)/ (2+5))
So, point B is at ((2x2 + 5x1) / 7 , (2y2 + 5y1)/ 7).

Express the given biconditional as the conjunction of two conditionals.
A.
If it is a pentagon, then it has five sides. If it is a polygon, then it is a pentagon.
B.
If it is a pentagon, then it is a polygon. If it is a polygon, then it is a pentagon.
C.
If it is a pentagon, then it is a polygon. If it is a polygon, then it has five sides.
D.
If it is a pentagon, then it has five sides. If the polygon has five sides, then it is a pentagon
Answer:
D. If it is a pentagon, then it has five sides. If the polygon has five sides, then it is a pentagon
Step-by-step explanation:
Given statements;
A polygon is a pentagon if and only if it has five sides.
Therefore, this bi-conditional statement is premised on two "if"s,
If it is a pentagon then we are dealing with a body with 5 sides.
And if such body has five sides, it is a polygon called pentagon
The correct option is D
Choice A, B and C are logically flawed.
A. If it is a pentagon, then it has five sides. If it is a polygon, then it is a pentagon.
The emboldened part we do not know.
B. If it is a pentagon, then it is a polygon. If it is a polygon, then it is a pentagon
The emboldened part is flawed.
C. If it is a pentagon, then it is a polygon. If it is a polygon, then it has five sides.
We do not know if all pentagons have 5 sides.
The conjunction of two conditional statement for the biconditional 'A polygon is a pentagon if and only if it has five sides' is 'If it is a pentagon, then it has five sides' and 'If a polygon has five sides, then it is a pentagon'.
The given biconditional statement 'A polygon is a pentagon if and only if it has five sides' can be split into two conditional statements as follows: 'If it is a pentagon, then it has five sides' and 'If a polygon has five sides, then it is a pentagon'.
These two separate conditional statements show both possible directions of the biconditional statement. Option D correctly represents these two conditions as the conjunction of two conditional statements.
