Multiply 3800 by 14 by 6.4% and you will get your answer
Answer:
The statistic would be given by:
(1)
And replacing we got:
Step-by-step explanation:
Information given
n=421 represent the random sample taken
estimated proportion of adults that would erase all of their personal information online if they could
is the value that we want to test
z would represent the statistic
Hypothesis to test
We want to check if Most adults would erase all of their personal information online if they could, then the system of hypothesis are :
Null hypothesis:
Alternative hypothesis:
The statistic would be given by:
(1)
And replacing we got:
Answer:
-2.0000 times -2.000 = 4
Step-by-step explanation:
Th area of a right triangle is A = 1/2 (ab), where a and b are the legs of the right angle. So area of the base is, A = 1/2 (9 x 12) = 108 cm2. With 2 bases, total area of base is 108 times 2, which is equal to 216 cm2. The other side of the triangular base nypotenuse) can be computed by Phythagorean theorem. Hypotenuse = square root of sum of the suare of 9 and 12. This is equal to 15 cm. There are other 3 rectangular faces with the following dimensions: 9 by 10 cm, 12 by 10 cm and 15 by 10 cm. Area of the other faces are 90, 120 and 150 cm2, by multiplying the length and width, only. Total area is 576 cm2.
Answer:
The coordinates of point Q' are: Q'(-3, 5)
Step-by-step explanation:
When a point P(x, y) is rotated 90° counterclockwise around the origin, we flip x and y and reverse the sign of y.
Thus,
The rule to rotate a point P(x, y) after a rotation 90° counterclockwise around the origin is:
P(x, y) → P'(-y, x)
In our case, rectangle PQRS is rotated 90° counterclockwise about the origin.
The rectangle has the coordinates:
We need to determine the coordinates of the point Q’.
Using the rule to rotate a point P(x, y) after a rotation 90° counterclockwise around the origin is:
P(x, y) → P'(-y, x)
Thus, coordinates of the point Q’ will be:
Q(5, 3) → Q'(-3, 5)
Therefore, the coordinates of point Q' are: Q'(-3, 5)
